fix(parser): do not omit < token opening type argument list (#26328)
Fix tokens produced when `<<` opens a type argument list. e.g.: ```typescript type Bar = ReturnType<<T>(x: T) => number>; ``` Previously only 1 `<` token was produced between `ReturnType` and `T`. This PR corrects that so 2 `<` tokens are produced. TS-ESLint get this wrong too - hence why this wasn't noticed before, as our conformance tests compare to TS-ESLint. PR submitted to fix TS-ESLint: https://github.com/typescript-eslint/typescript-eslint/pull/12821 In meantime, this PR skips the erroneously failing ESTree tokens conformance tests. We can can re-enable those tests once the fix lands in TS-ESLint. |

fix(estree): emit decorators on FormalParameterRest (#25582)
This PR adds support for emitting `decorators` when serializing an ast to ESTree (both with/without raw transfer).
Given the following code:
```
class C { method(@dec ...args) {} }
```
Before we emitted the following ESTree shape:
```json
"params": [
{
"type": "RestElement",
"decorators": [],
"argument": {
"type": "Identifier",
"decorators": [],
"name": "args",
"optional": false,
"typeAnnotation": null,
},
"optional": false,
"typeAnnotation": null,
"value": null,
}
],
```
Now we emit:
```json
"params": [
{
"type": "RestElement",
"decorators": [
{
"type": "Decorator",
"expression": { "type": "Identifier", "name": "dec" }
}
],
"argument": {
"type": "Identifier",
"decorators": [],
"name": "args",
"optional": false,
"typeAnnotation": null,
},
"optional": false,
"typeAnnotation": null,
"value": null,
},
],
```

test(napi/parser): fix TypeScript test case splitting (#25492)
#25488 copied the code from `napi/parser` for splitting TypeScript test fixtures. AI reviewer correctly pointed out that it was clearly broken: https://github.com/oxc-project/oxc/pull/25488#discussion_r3754102027 Turns out all this code was pointless. It looks up the error codes TypeScript provides for its fixtures, but that's not needed here. And in any case (according to Claude at least) the logic wasn't correctly ported from the Rust version, so it wouldn't work anyway. So this PR just deletes it all. If #25488 is merged, this will keep the 2 copies in sync with each other. |

feat(ast)!: group class heritage into ClassHeritage (#25360)
## Summary
- Groups `Class::super_class` and `Class::super_type_arguments` into `Class::heritage`.
- Introduces `ClassHeritage` containing the superclass expression and its optional TypeScript type arguments.
- Makes superclass type arguments without a superclass expression unrepresentable.
## Breaking Change
The Rust AST changes from:
```rust
pub struct Class<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub r#type: ClassType,
pub decorators: Vec<'a, Decorator<'a>>,
pub id: Option<BindingIdentifier<'a>>,
#[ts]
pub type_parameters: Option<Box<'a, TSTypeParameterDeclaration<'a>>>,
pub super_class: Option<Expression<'a>>,
#[ts]
pub super_type_arguments: Option<Box<'a, TSTypeParameterInstantiation<'a>>>,
#[ts]
pub implements: Vec<'a, TSClassImplements<'a>>,
pub body: Box<'a, ClassBody<'a>>,
#[ts]
pub r#abstract: bool,
#[ts]
pub declare: bool,
pub scope_id: Cell<Option<ScopeId>>,
}
```
to:
```rust
pub struct Class<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub r#type: ClassType,
pub decorators: Vec<'a, Decorator<'a>>,
pub id: Option<BindingIdentifier<'a>>,
#[ts]
pub type_parameters: Option<Box<'a, TSTypeParameterDeclaration<'a>>>,
pub heritage: Option<ClassHeritage<'a>>,
#[ts]
pub implements: Vec<'a, TSClassImplements<'a>>,
pub body: Box<'a, ClassBody<'a>>,
#[ts]
pub r#abstract: bool,
#[ts]
pub declare: bool,
pub scope_id: Cell<Option<ScopeId>>,
}
pub struct ClassHeritage<'a> {
pub expression: Expression<'a>,
#[ts]
pub type_arguments: Option<Box<'a, TSTypeParameterInstantiation<'a>>>,
}
```
## Why?
ECMAScript defines the complete `extends` clause as `ClassHeritage`:
```text
ClassHeritage : extends LeftHandSideExpression
```
TypeScript additionally permits type arguments on the heritage expression:
```ts
class Derived extends Base<T> {}
```
Previously, the AST stored the expression and type arguments independently:
```text
Class {
super_class: Some(Base),
super_type_arguments: Some(<T>),
...
}
```
This allowed an invalid state to be constructed:
```text
Class {
super_class: None,
super_type_arguments: Some(<T>),
...
}
```
Superclass type arguments cannot exist without an `extends` expression.
The parser already treated these fields as a pair. It parsed a class heritage entry and then split its expression and type arguments into two independent fields. Builders and transforms therefore had to preserve their relationship manually.
Grouping them into `ClassHeritage` makes the syntactic dependency explicit and prevents consumers from observing or constructing contradictory class heritage.
## Class heritage forms
A class without an `extends` clause has no heritage:
```js
class Base {}
```
```text
Class {
heritage: None,
...
}
```
A class extending an expression has heritage without type arguments:
```js
class Derived extends Base {}
```
```text
Class {
heritage: Some(ClassHeritage {
expression: Base,
type_arguments: None,
}),
...
}
```
TypeScript type arguments belong to the same heritage structure:
```ts
class Derived extends Base<T> {}
```
```text
Class {
heritage: Some(ClassHeritage {
expression: Base,
type_arguments: Some(<T>),
}),
...
}
```
The heritage expression may be any valid class heritage expression:
```js
class Derived extends mixin(Base) {}
class NullDerived extends null {}
```
## How to migrate
Code that previously accessed the superclass expression directly:
```rust
if let Some(super_class) = &class.super_class {
// ...
}
```
can use the compatibility accessor:
```rust
if let Some(super_class) = class.super_class() {
// ...
}
```
Code that needs both parts should access the grouped heritage:
```rust
if let Some(heritage) = &class.heritage {
let expression = &heritage.expression;
let type_arguments = heritage.type_arguments.as_deref();
}
```
Mutating consumers should update the nested fields:
```rust
if let Some(heritage) = &mut class.heritage {
heritage.type_arguments = None;
}
```
Common migrations:
| Previous representation | New representation |
| --- | --- |
| `class.super_class` | `class.heritage.as_ref().map(\|h\| &h.expression)` or `class.super_class()` |
| `class.super_type_arguments` | `class.heritage.as_ref()?.type_arguments` or `class.super_type_arguments()` |
| `class.super_class.is_some()` | `class.heritage.is_some()` |
| Mutate `class.super_class` | Mutate `class.heritage.expression` |
| Clear `class.super_type_arguments` | Clear `class.heritage.type_arguments` |
| Pass superclass and type arguments separately to a `Class` builder | Construct and pass `ClassHeritage` |
| Clone both fields independently | Clone `class.heritage` |
```ts
superClass: Expression | null;
superTypeArguments?: TSTypeParameterInstantiation | null;
```
No `heritage` property or `ClassHeritage` node is added to the ESTree output.

feat(ast)!: narrow TSInterfaceHeritage::expression to TSTypeName (#24360)
## Summary
Narrow `TSInterfaceHeritage` from a general JavaScript `Expression` to `TSTypeName`.
```rust
pub struct TSInterfaceHeritage<'a> {
pub type_name: TSTypeName<'a>,
pub type_arguments: Option<Box<'a, TSTypeParameterInstantiation<'a>>>,
}
```
## Breaking Change
The Rust AST field changes from:
```rust
expression: Expression<'a>
```
to:
```rust
type_name: TSTypeName<'a>
```
## Why?
The current AST can represent shapes such as:
```ts
interface A extends foo() {}
interface A extends A + B {}
interface A extends new Foo() {}
interface A extends true {}
```
Which is an overly wide type since all of the above variants are invalid.
This PR tightens up the AST, making these invalid variants irrepresentable.
## How to migrate?
This should be a trivial migration:
1. instead of accessing `expression` on `TSInterfaceHeritage`, now access `type_name`
2. change any pattern matching on the `type_name` field to use `TypeName` (this is a smaller subset so should allow deleting code!)

feat(ast)!: remove duplicated VariableDeclarator::kind (#25319)
## Summary
- Removes `VariableDeclarator::kind`.
- Makes `VariableDeclaration::kind` the single source of truth for every declarator in its declaration list.
- Makes contradictory parent and child declaration kinds unrepresentable.
## Breaking Change
The Rust AST changes from:
```rust
pub struct VariableDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub kind: VariableDeclarationKind,
pub declarations: Vec<'a, VariableDeclarator<'a>>,
#[ts]
pub declare: bool,
}
pub struct VariableDeclarator<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
#[estree(skip)]
pub kind: VariableDeclarationKind,
#[estree(via = VariableDeclaratorId)]
pub id: BindingPattern<'a>,
#[ts]
#[estree(skip)]
pub type_annotation: Option<Box<'a, TSTypeAnnotation<'a>>>,
pub init: Option<Expression<'a>>,
#[ts]
pub definite: bool,
}
```
to:
```rust
pub struct VariableDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub kind: VariableDeclarationKind,
pub declarations: Vec<'a, VariableDeclarator<'a>>,
#[ts]
pub declare: bool,
}
pub struct VariableDeclarator<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
#[estree(via = VariableDeclaratorId)]
pub id: BindingPattern<'a>,
#[ts]
#[estree(skip)]
pub type_annotation: Option<Box<'a, TSTypeAnnotation<'a>>>,
pub init: Option<Expression<'a>>,
#[ts]
pub definite: bool,
}
```
## Why?
A variable declaration has one declaration kind shared by every declarator in its declaration list:
```js
const first = 1, second = 2;
```
Previously, the AST stored that kind on both the parent declaration and every child declarator:
```text
VariableDeclaration {
kind: Const,
declarations: [
VariableDeclarator { kind: Const, ... },
VariableDeclarator { kind: Const, ... },
],
}
```
This allowed contradictory ASTs to be constructed:
```text
VariableDeclaration {
kind: Const,
declarations: [
VariableDeclarator { kind: Var, ... },
],
}
```
Different consumers read different copies:
- Code generation used `VariableDeclaration::kind`.
- Semantic binding used `VariableDeclarator::kind`.
- Lint rules, transforms, and minifier passes used a mixture of both.
As a result, one AST could be emitted as `const` while its binding was treated as function-scoped `var`.
Transforms also had to keep the copies synchronized manually. For example, const-to-let normalization updated the parent and then looped through every declarator to update each child. Explicit resource management performed similar paired mutations for `using` declarations.
Keeping the kind only on `VariableDeclaration` removes this synchronization requirement and prevents consumers from observing conflicting declaration semantics.
## Declaration forms
The declaration kind now belongs exclusively to the node that owns the declaration list:
```js
let value;
```
```text
VariableDeclaration {
kind: Let,
declarations: [
VariableDeclarator { id: value, ... },
],
}
```
Multiple declarators share the same parent kind:
```js
const first = 1, second = 2;
```
```text
VariableDeclaration {
kind: Const,
declarations: [
VariableDeclarator { id: first, ... },
VariableDeclarator { id: second, ... },
],
}
```
## How to migrate
Code that previously read the kind from a declarator:
```rust
if declarator.kind.is_const() {
// ...
}
```
should now read it from the containing declaration:
```rust
if declaration.kind.is_const() {
// ...
}
```
Consumers operating through an AST node store should retrieve the parent `VariableDeclaration`:
```rust
let AstKind::VariableDeclaration(declaration) =
nodes.parent_kind(declarator.node_id())
else {
unreachable!();
};
let kind = declaration.kind;
```
Common migrations:
| Previous representation | New representation |
| --- | --- |
| `declarator.kind` | Containing `declaration.kind` |
| Match `VariableDeclarator::kind` during semantic binding | Read the parent `VariableDeclaration` from ancestry |
| Pass `kind` to `VariableDeclarator::new` | Remove the `kind` argument |
| Update parent and every child kind | Update only `VariableDeclaration::kind` |
| Recover kind after detaching a declarator | Capture or pass the parent kind before detaching it |
| Inspect a symbol’s declarator kind in lint rules | Resolve its parent declaration through the node store |
When constructing declarators, use the generated kindless `VariableDeclarator` builders and place them inside a `VariableDeclaration` carrying the required kind.

feat(ast)!: split TS external modules & Namespace Declarations (#25284)
## Summary
- Splits `TSModuleDeclaration` into two dedicated declaration nodes:
- `TSExternalModuleDeclaration` for string-literal modules and module augmentations.
- `TSNamespaceDeclaration` for identifier-based `module` and `namespace` declarations.
- Removes `TSModuleDeclaration`, `TSModuleDeclarationName`, `TSModuleDeclarationBody`, and `TSModuleDeclarationKind`.
- Makes invalid combinations of names, bodies, and declaration kinds unrepresentable.
- Ensures only namespace declarations introduce a normal binding.
- Updates all AST consumers, generators, traversal, formatting, code generation, semantic analysis, lint rules, transforms, and serialization.
- Keeps normal and eager-raw ESTree output compatible: both declarations remain `TSModuleDeclaration` nodes.
- Allows experimental lazy raw deserialization to expose the two new node types directly.
## Breaking Change
The Rust AST changes from:
```rust
pub enum Declaration<'a> {
VariableDeclaration(Box<'a, VariableDeclaration<'a>>) = 32,
FunctionDeclaration(Box<'a, Function<'a>>) = 33,
ClassDeclaration(Box<'a, Class<'a>>) = 34,
TSTypeAliasDeclaration(Box<'a, TSTypeAliasDeclaration<'a>>) = 35,
TSInterfaceDeclaration(Box<'a, TSInterfaceDeclaration<'a>>) = 36,
TSEnumDeclaration(Box<'a, TSEnumDeclaration<'a>>) = 37,
TSModuleDeclaration(Box<'a, TSModuleDeclaration<'a>>) = 38,
TSGlobalDeclaration(Box<'a, TSGlobalDeclaration<'a>>) = 39,
TSImportEqualsDeclaration(Box<'a, TSImportEqualsDeclaration<'a>>) = 40,
}
pub struct TSModuleDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub id: TSModuleDeclarationName<'a>,
pub body: Option<TSModuleDeclarationBody<'a>>,
pub kind: TSModuleDeclarationKind,
pub declare: bool,
pub scope_id: Cell<Option<ScopeId>>,
}
```
to:
```rust
pub enum Declaration<'a> {
VariableDeclaration(Box<'a, VariableDeclaration<'a>>) = 32,
FunctionDeclaration(Box<'a, Function<'a>>) = 33,
ClassDeclaration(Box<'a, Class<'a>>) = 34,
TSTypeAliasDeclaration(Box<'a, TSTypeAliasDeclaration<'a>>) = 35,
TSInterfaceDeclaration(Box<'a, TSInterfaceDeclaration<'a>>) = 36,
TSEnumDeclaration(Box<'a, TSEnumDeclaration<'a>>) = 37,
TSExternalModuleDeclaration(Box<'a, TSExternalModuleDeclaration<'a>>) = 38,
TSNamespaceDeclaration(Box<'a, TSNamespaceDeclaration<'a>>) = 39,
TSGlobalDeclaration(Box<'a, TSGlobalDeclaration<'a>>) = 40,
TSImportEqualsDeclaration(Box<'a, TSImportEqualsDeclaration<'a>>) = 41,
}
pub struct TSExternalModuleDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub id: StringLiteral<'a>,
pub body: Option<Box<'a, TSModuleBlock<'a>>>,
pub declare: bool,
pub scope_id: Cell<Option<ScopeId>>,
}
pub struct TSNamespaceDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub id: BindingIdentifier<'a>,
pub body: TSNamespaceDeclarationBody<'a>,
pub kind: TSNamespaceDeclarationKind,
pub declare: bool,
pub scope_id: Cell<Option<ScopeId>>,
}
pub enum TSNamespaceDeclarationBody<'a> {
TSNamespaceDeclaration(Box<'a, TSNamespaceDeclaration<'a>>) = 0,
TSModuleBlock(Box<'a, TSModuleBlock<'a>>) = 1,
}
pub enum TSNamespaceDeclarationKind {
Module = 0,
Namespace = 1,
}
```
The corresponding inherited `Statement` variants, `AstKind` variants, builders, and visitor methods have also changed.
## Why?
`TSModuleDeclaration` previously represented two declaration families with different syntax and semantics:
```ts
declare module "foo" {}
declare module "*.css";
module Foo {}
namespace Foo {}
namespace Foo.Bar {}
```
The shared representation allowed invalid states such as:
- A namespace with a string-literal name.
- An external module with an identifier name.
- An identifier namespace without a body.
- A dotted external module.
- An external module containing another module declaration as its body.
- A declaration whose `kind` disagreed with its name.
Consumers also had to inspect `id` before determining whether the node introduced a binding or represented an external module.
The two declaration families have stronger independent invariants:
### External modules
- Always have a string-literal name.
- Never introduce a normal binding identifier.
- May omit their body.
- Cannot use dotted names.
- Use module-body import and export rules.
### Namespace declarations
- Always have a binding identifier.
- Always have a body.
- May contain nested namespace declarations for dotted names.
- Explicitly preserve the `module` or `namespace` spelling.
- Introduce a namespace/module symbol.
- Use namespace-body restrictions.
Dedicated nodes encode these differences directly.
## Declaration forms
External modules use `TSExternalModuleDeclaration`:
```ts
declare module "foo" {}
declare module "*.css";
module "foo" {}
```
Identifier-based declarations use `TSNamespaceDeclaration`:
```ts
module Foo {}
namespace Foo {}
```
Dotted namespaces are represented as nested namespace declarations:
```ts
namespace Foo.Bar {}
```
```rust
TSNamespaceDeclaration {
id: Foo,
body: TSNamespaceDeclarationBody::TSNamespaceDeclaration(
TSNamespaceDeclaration {
id: Bar,
body: TSNamespaceDeclarationBody::TSModuleBlock(...),
// ...
}
),
// ...
}
```
Only `TSExternalModuleDeclaration::body` is optional.
## ESTree compatibility
Normal serialization and eager raw deserialization continue to emit the existing ESTree shape:
```ts
interface TSModuleDeclaration {
type: "TSModuleDeclaration";
id: BindingIdentifier | StringLiteral | TSQualifiedName;
body: TSModuleBlock | null;
kind: "module" | "namespace";
declare: boolean;
global: false;
}
```
Dotted namespaces continue to serialize as a single `TSModuleDeclaration` with a `TSQualifiedName`.
Experimental lazy raw deserialization is not compatibility-preserving. It now exposes `TSExternalModuleDeclaration` and `TSNamespaceDeclaration` directly, with separate constructors, layouts, and visitor type IDs.
## How to migrate
Code that previously matched all forms through one variant:
```rust
if let Declaration::TSModuleDeclaration(declaration) = declaration {
// ...
}
```
should now match the required declaration family:
```rust
match declaration {
Declaration::TSExternalModuleDeclaration(declaration) => {
// String-literal external module
}
Declaration::TSNamespaceDeclaration(declaration) => {
// Identifier-based module or namespace
}
_ => {}
}
```
The same applies to `Statement` and `AstKind`:
```rust
Statement::TSExternalModuleDeclaration(declaration)
Statement::TSNamespaceDeclaration(declaration)
AstKind::TSExternalModuleDeclaration(declaration)
AstKind::TSNamespaceDeclaration(declaration)
```
Common field migrations:
| Previous representation | New representation |
| --- | --- |
| `TSModuleDeclarationName::StringLiteral(id)` | `TSExternalModuleDeclaration::id` |
| `TSModuleDeclarationName::Identifier(id)` | `TSNamespaceDeclaration::id` |
| `body: None` | Only valid on `TSExternalModuleDeclaration` |
| `TSModuleDeclarationBody::TSModuleBlock` | External `body` or `TSNamespaceDeclarationBody::TSModuleBlock` |
| `TSModuleDeclarationBody::TSModuleDeclaration` | `TSNamespaceDeclarationBody::TSNamespaceDeclaration` |
| `TSModuleDeclarationKind::Module` | External module, or `TSNamespaceDeclarationKind::Module` |
| `TSModuleDeclarationKind::Namespace` | `TSNamespaceDeclarationKind::Namespace` |
| Inspect `id` to determine binding behavior | Match `TSNamespaceDeclaration` |
| `declaration.id()` for string modules | Now returns `None` |
| `visit_ts_module_declaration` | `visit_ts_external_module_declaration` or `visit_ts_namespace_declaration` |
When constructing nodes, use the generated `TSExternalModuleDeclaration` or `TSNamespaceDeclaration` builders rather than recreating the previous shared representation.

fix(napi): omit parser header from WASI declarations (#25254)
## Summary - generate the parser WASI declaration without the root package's custom DTS header - remove the resulting invalid `./generated/visit/visitor.d.ts` import from `parser.wasi.d.cts` - allow `@napi-rs/cli` 3.8.2 to validate and publish the WASI binding package Failed job: https://github.com/oxc-project/oxc/actions/runs/30810594648/job/91677775732 The custom header describes the root `oxc-parser` JavaScript wrapper (`Visitor` and `visitorKeys`), not the raw platform binding package, so it should not be present in the WASI binding declaration. |

feat(ast)!: introduce ExportDeclaration, ExportFromDeclaration (#25095)
## Summary
Split the overloaded Rust `ExportNamedDeclaration` into syntax-specific AST nodes:
- `ExportDeclaration` for exported declarations
- `ExportNamedDeclaration` for local exports
- `ExportFromDeclaration` for re-exports
## Breaking Change
The Rust AST changes from:
```rust
pub struct ExportNamedDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub declaration: Option<Declaration<'a>>,
pub specifiers: Vec<'a, ExportSpecifier<'a>>,
pub source: Option<StringLiteral<'a>>,
pub export_kind: ImportOrExportKind,
pub with_clause: Option<Box<'a, WithClause<'a>>>,
}
pub enum ModuleDeclaration<'a> {
// ...
ExportNamedDeclaration(Box<'a, ExportNamedDeclaration<'a>>),
// ...
}
```
to:
```rust
pub struct ExportDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub declaration: Declaration<'a>,
}
pub struct ExportNamedDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub specifiers: Vec<'a, ExportSpecifier<'a>>,
pub export_kind: ImportOrExportKind,
}
pub struct ExportFromDeclaration<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub specifiers: Vec<'a, ExportSpecifier<'a>>,
pub source: StringLiteral<'a>,
pub export_kind: ImportOrExportKind,
pub with_clause: Option<Box<'a, WithClause<'a>>>,
}
pub enum ModuleDeclaration<'a> {
// ...
ExportDeclaration(Box<'a, ExportDeclaration<'a>>),
ExportNamedDeclaration(Box<'a, ExportNamedDeclaration<'a>>),
ExportFromDeclaration(Box<'a, ExportFromDeclaration<'a>>),
// ...
}
```
## Why?
The previous node represented three distinct syntax forms through optional and mutually exclusive fields:
```text
export const value = 1; -> ExportDeclaration
export { value }; -> ExportNamedDeclaration
export { value } from "mod"; -> ExportFromDeclaration
```
This allowed invalid combinations such as declarations with specifiers or sources, and import attributes without a source. The new nodes make these states unrepresentable and remove repeated `declaration`/`source` branching from consumers.
## How to migrate
Match the syntax-specific `ModuleDeclaration`, `Statement`, or `AstKind` variant instead of inspecting optional fields. Generated builders, visitors, traversal ancestors, and formatter wrappers now expose corresponding APIs for all three nodes.
Common field migrations:
| Previous representation | New representation |
| --- | --- |
| `declaration: Some(declaration)` | `ExportDeclaration { declaration }` |
| `declaration.as_ref()` | `&export.declaration` |
| `source.is_none()` for local exports | Match `ExportNamedDeclaration` |
| `source: Some(source)` | `ExportFromDeclaration { source }` |
| `source.as_ref().unwrap()` | `&export.source` |
| `with_clause` | Only available on `ExportFromDeclaration` |
| Stored `export_kind` on exported declarations | `ExportDeclaration::export_kind()` |
| `ExportNamedDeclaration::boxed_plain_declaration(...)` | `ExportDeclaration::boxed(...)` |
| `ExportNamedDeclaration::boxed(..., None, specifiers, None, ...)` | `ExportNamedDeclaration::boxed(..., specifiers, ...)` |
| `ExportNamedDeclaration::boxed(..., None, specifiers, Some(source), ...)` | `ExportFromDeclaration::boxed(..., specifiers, source, ...)` |

feat(ast)!: introduce ArrowFunctionBody enum (#24987)
## Summary
- Introduces `ArrowFunctionBody` to represent concise expression and block bodies explicitly.
- Removes the `ArrowFunctionExpression::expression` boolean.
- Makes invalid arrow body combinations unrepresentable.
## Breaking Change
The Rust AST changes from:
```rust
pub struct ArrowFunctionExpression<'a> {
pub expression: bool,
pub body: Box<'a, FunctionBody<'a>>,
}
```
to:
```rust
pub enum ArrowFunctionBody<'a> {
FunctionBody(Box<'a, FunctionBody<'a>>) = 64,
INHERIT(Expression<'a>),
}
pub struct ArrowFunctionExpression<'a> {
pub body: ArrowFunctionBody<'a>,
}
```
Concise arrow bodies are now stored directly as expressions instead of synthetic `FunctionBody` and `ExpressionStatement` nodes. Block bodies continue to use `FunctionBody`.
## Why?
The previous representation required consumers to maintain this implicit invariant:
```text
expression == true
→ no directives
→ exactly one statement
→ that statement is an ExpressionStatement
```
Invalid combinations could cause panics, skipped work, or fallback behavior. The enum encodes the grammar directly and makes those invalid states unrepresentable.
Concise expressions also now have `ArrowFunctionExpression` as their direct traversal ancestor, without synthetic `FunctionBody` or `ExpressionStatement` nodes.
## How to migrate
Use the arrow body accessors or match on `ArrowFunctionBody` rather than inspecting `expression` and synthetic statements.
Common field migrations:
| Previous representation | New representation |
| --- | --- |
| `arrow.expression` | `arrow.is_expression()` |
| `arrow.get_expression()` | `arrow.get_expression()` |
| `&arrow.body.statements` | `arrow.get_function_body().map(\|body\| &body.statements)` |
| `&mut arrow.body.statements` | `arrow.get_function_body_mut().map(\|body\| &mut body.statements)` |
| Synthetic expression statement in `arrow.body` | Direct `ArrowFunctionBody` expression variant |
| `arrow.body = function_body` | `arrow.body = ArrowFunctionBody::FunctionBody(function_body)` |
| Expression-to-block conversion | Create a `FunctionBody` containing a return statement |
| Block-to-expression conversion | Assign the expression directly to `arrow.body` |
| Builder `(expression, body)` arguments | Pass a single `ArrowFunctionBody` |

feat(ast_visit): add Utf8ToUtf16::convert_program_and_comments (#24859)
Add a method `Utf8ToUtf16::convert_program_and_comments`, and use it in a couple of places. This is marginally faster than `convert_program` followed by `convert_comments`, as it avoids branching on the same condition twice. |

fix(estree): handle empty spans serializing ImportMeta and NewTarget (#24775)
Follow-on after #24557. Handle when `ImportMeta` / `NewTarget` has an empty span (`SPAN`). This code path is not exercised at present, but it seems a good idea to be prepared for when we may serialize AST after transformation. |

docs(napi/parser): remove erroneous comment (#24730)
Remove a comment which said something that isn't true! ASM analysis shows that the mask does not remove the bounds check on accessing the array. |

feat(minfier): drop last break from last switch case (#24673)
After many trial and errors, this seem to be the best way to remove break stmts in switch cases, This change targets only last break in last case of switch smts if its unlabelled this change differs from #23914 as its no longer targets all branches as that should not be no longer necessary if all cases are correctly rewritten https://github.com/oxc-project/oxc/issues/24672 ----- cases like `switch (a) { case 3: if (b) break; }` are not changed ----- ref: #17544 |

feat(ast)!: split MetaProperty into ImportMeta and NewTarget (#24557)
## Summary
- replace the generic Rust MetaProperty AST node with dedicated ImportMeta and NewTarget nodes
- preserve the ESTree MetaProperty shape and generated public TypeScript types
- update parser, formatter, codegen, lint, transform, minifier, traversal, and React compiler consumers
## Summary
Remove `MetaProperty` AST node, in favour of two separate nodes (`ImportMeta` and `NewTarget`)
## Breaking Change
The Rust AST field changes from:
```rust
pub struct MetaProperty<'a> {
pub node_id: Cell<NodeId>,
pub span: Span,
pub meta: IdentifierName<'a>,
pub property: IdentifierName<'a>,
}
```
to:
```rust
/// /// `import.meta` in `console.log(import.meta);`.
pub struct ImportMeta {
pub node_id: Cell<NodeId>,
pub span: Span,
}
/// `new.target` in `function F() { return new.target; }`.
pub struct NewTarget {
pub node_id: Cell<NodeId>,
pub span: Span,
}
```
## Why?
The current AST could represent shapes such as:
```
foo.bar
```
By constructing the node manually. However this doesn't make sense, and is invalid.
## How to migrate?
1. Replace any `Expression::MetaProperty` matches/checks with the dedicated `Expression::ImportMeta` and `Expression::NewTarget` varients
2. Replace any `new_meta_property` construction with the new `new_import_meta` or `new_new_target` APIs.
3. Inspecting the `meta`/`property` identifier names is no longer required.

feat(parser): add ParseOptions::enable_ident_hashes (#24491)
Adds `ParseOptions::enable_ident_hashes` (default `true`) and `Ident::new_unhashed` in `oxc_str`, and turns it off in the parse-only paths of the `oxc-parser` napi crate and the JS/JSON formatters. ### Why `Ident`'s precomputed hash (#19143) is a parse-time investment that pays off in semantic analysis — but parse-only consumers (parse + serialize, formatting) pay it for nothing. Profiling against other native parsers showed identifier hashing at 3.5-4.6% of parse time. Measured on M-series (yuku-style native harness, 50 warmup + 300 runs, median): | fixture | default | option off | |---|---|---| | react.development.js | 0.156 ms | 0.152 ms (−2.3%) | | binder.ts | 0.383 ms | 0.370 ms (−3.5%) | | App.tsx | 1.140 ms | 1.111 ms (−2.5%) | | checker.ts | 7.862 ms | 7.499 ms (−4.6%) | | typescript.js | 25.07 ms | 24.16 ms (−3.6%) | ### Contract Unhashed `Ident`s store hash `0`; `Eq`/`Hash`/`ContentEq` include the stored hash, so unhashed and hashed `Ident`s of the same string do not compare equal. Semantic analysis (or anything relying on `Ident` hashing) must not run on an AST parsed with the option disabled. Default behavior is unchanged. Every `Ident` the parser creates funnels through the `ParserImpl::ident()` helper, so the option applies uniformly. This covers identifiers lexed directly (`parse_identifier_kind`, `parse_private_identifier`) as well as those reconstructed from a `&str`/`Str` — import/export specifier locals, JSX element/member names, the TS `intrinsic` type name, TS import-type option keys (`with`/`assert`), and the `import x = this` recovery path — which would otherwise always be hashed through `Into<Ident>`. Exhaustively checked by parsing the test262/babel/typescript/misc/prettier corpora (96.5k files, 5.6M identifiers) in both option states and walking every `Ident` in the AST. On 64-bit platforms `Ident::new_unhashed` compiles to a no-op: an unhashed `Ident` has the same layout and bit representation as `&str`. ### Opt-outs - **napi `oxc-parser`** ties `enable_ident_hashes` to whether semantic errors are requested. Both parse entry points run `SemanticBuilder` only when `showSemanticErrors` is set, so the common parse-and-serialize path skips hashing while the semantic-errors path keeps it. Serialized output is unchanged — the hash is internal to `Ident` and never emitted. - **JS and JSON formatters** turn it off: they never run semantic analysis and only read `Ident::as_str` / compare idents against string literals. Exception: the JS formatter keeps hashes when built with the `detect_code_removal` feature, whose check runs `SemanticBuilder` on the formatter-parsed AST. |

refactor(napi): don't force tokio_rt on the napi binding crates (#24475)
## What
Stop forcing `tokio_rt` on oxc's napi binding crates.
`tokio_rt` was enabled as a blanket default on the workspace `napi` dependency, so **every** napi crate pulled in tokio. But the napi binding crates don't use a tokio runtime:
- no `#[napi] async fn` exports and no `tokio::` usage anywhere in the napi crates
- the only async surface is `oxc_parser_napi`'s `parse_async`, which is a libuv-backed `AsyncTask` / `Task` (napi4), **not** a tokio future
## Change (2 lines)
- workspace `Cargo.toml`: `napi = { version = "3", features = ["tokio_rt"] }` → `napi = { version = "3" }` — napi's own `default` already provides `napi4` + `dyn-symbols`, which covers `AsyncTask`
- `napi/parser/Cargo.toml`: drop the now-redundant `features = ["async"]`
## Effect
- oxc's napi crates (`oxc_napi`, `oxc_parser_napi`, `oxc_transform_napi`, `oxc_minify_napi`) no longer link tokio → smaller npm binaries
- downstream consumers that share the same `napi` (e.g. a bundler wiring napi's pluggable async-runtime SPI) are no longer forced to pull tokio in via Cargo feature unification
- crates that genuinely want napi's tokio async (`oxlint`, `oxfmt`) keep opting in explicitly via `features = ["async"]`
## Verification
- `cargo check --workspace` — green
- `cargo tree -i tokio` shows tokio gone from all four napi crates' normal dependency trees; `napi` now resolves to just `default` (`napi4` + `dyn-symbols`)
- CI validates the JS-side async parse (`parse_async`) tests

<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Low Risk**
> Dependency-feature-only change with explicit opt-in preserved for crates that need napi async; async parse paths use `Task`/`AsyncTask`, not Tokio futures.
>
> **Overview**
> Removes **`tokio_rt`** from the workspace **`napi`** dependency so NAPI binding crates no longer inherit Tokio through Cargo feature unification. **`napi/parser`** also drops the redundant **`features = ["async"]`** on its **`napi`** line.
>
> Published NAPI crates (`oxc_parser_napi`, `oxc_transform_napi`, etc.) should link a smaller native addon while **`parse`** / **`parse_raw`** keep using **`AsyncTask`** / **`Task`** (napi4), not napi’s Tokio async runtime. Crates that need napi async (**`oxlint`**, **`oxfmt`**, playground) still enable **`features = ["async"]`** locally.
