perf(diagnostics): migrate to allocation-optimized oxc-miette ( #23094 )
...
## Summary
Adopts the allocation-optimized oxc-miette diagnostic APIs (oxc-miette v3):
- `OxcDiagnostic` stores labels in `miette::Labels` (1–2 inline, no `Vec`); **drops the `smallvec` dependency**.
- `Diagnostic::labels`/`related` return owned inline containers; `code`/`help`/`note`/`url` return `Cow<str>`; `SourceCode::read_span` returns the concrete `MietteSpanContents` — all consumer call sites updated (linter `fixer`/`lib`/`runtime`/`tsgolint`, `oxc_napi`, napi/parser, oxlint LSP, coverage).
- `usize → u32` span conversions for the u32 `SourceSpan`.
## Allocation impact (parser benchmark)
`just allocs` — **~33% fewer sys allocations, no change in reallocations**:
| File | Sys allocs (before → after) | Sys reallocs |
|------|---|---|
| checker.ts | 5303 → 3543 | 10 (unchanged) |
| antd.js | 5392 → 3720 | 221 (unchanged) |
| App.tsx | 632 → 444 | 13 (unchanged) |
| pdf.mjs | 518 → 356 | 67 (unchanged) |
| binder.ts | 281 → 169 | 0 (unchanged) |
(The inline `Labels` removes the per-diagnostic `Vec`; an earlier `Box<str>` realloc regression was fixed in oxc-miette before this snapshot was taken.)

fix(oxfmt): avoid JS promise rejects for all TSFN call sites ( #23107 )
...
Fixes #20525 , (thanks @oxura !)
```sh
# Many files that route to the Prettier `formatFile` callback and fail to parse
mkdir -p /tmp/repro
for i in $(seq 1 500); do printf '<template><div></template>' > /tmp/repro/broken$i.vue; done
# Run repeatedly with default concurrency
for run in $(seq 1 10); do node apps/oxfmt/dist/cli.js --write /tmp/repro; done
```
Within a few runs it crashes non-deterministically (exit codes varied: 133 / 138 / 139, and sometimes 2 = clean error report), with the same fatal as #20525 :
```
# Fatal error in , line 0
# Check failed: object_ != kGlobalHandleZapValue. (or: node->IsInUse())
...
napi_reference_unref
<napi::error::Error as ...Drop>::drop
core::ptr::drop_in_place<napi::error::Error>
oxfmt::core::external_formatter::wrap_format_file::{{closure}}
```
Each broken file makes the `formatFile` callback reject; the resulting `napi::Error` is dropped on the TSFN await path and reaches `napi_reference_unref` during teardown → V8 fatal check.
After this fix (callback resolves errors as data), the same workload runs clean.

refactor(linter): share "alway" | "never" option across rules ( #23099 )
...
Skipped two rules because their defaults are "never".
- `react/jsx-boolean-value`
- `eslint/unicode-bom`
Tried to avoid the `Clone` derive 🤞 and simplified `operator-assignment`.
Sadly some docs are getting removed. Feel free to close the issue if the docs are preferred over a shared option.

feat(linter/unicorn): support no-null checkArguments option ( #23098 )

- Support `checkArguments` in `unicorn/no-null`, defaulting to upstream behavior of checking direct call and constructor arguments.
- Allow direct `null` call/constructor arguments when `checkArguments: false`, while still reporting nested `null` values.
- Port the missing upstream Unicorn cases and update generated config artifacts.

### Highlights
We are introducing `@codspeed/playwright`, for walltime benchmarking and
profiling of end to end browser applications through playwright.
Here's an example usage, but head to the
[docs](https://codspeed.io/docs/benchmarks/nodejs/playwright ) for more
information
```typescript
import { bench, type Page } from "@​codspeed/playwright-plugin";
import electronExecutable from "electron";
import path from "node:path";
import { fileURLToPath } from "node:url";
const __dirname = path.dirname(fileURLToPath(import.meta.url));
const appRoot = path.resolve(__dirname, "..");
async function waitUntilSettled(page: Page): Promise<void> {
await page.waitForFunction(() => {
const main = document.getElementById("main");
return !!main && !main.classList.contains("loading");
});
}
await bench(
"inbox-search-archive-threads",
async ({ page }) => {
await page.fill("#search", "update");
await waitUntilSettled(page);
await page.click("#select-visible-btn");
await page.click("#archive-btn");
await waitUntilSettled(page);
await page.click('#sidebar nav button[data-view="threads"]');
await waitUntilSettled(page);
},
{
target: {
kind: "electron",
appPath: path.join(appRoot, "out/main/index.js"),
cwd: appRoot,
},
beforeRound: async ({ page }) => {
page.setDefaultTimeout(180_000);
await page.waitForSelector("#main");
await waitUntilSettled(page);
},
},
);
```
Note: this plugin is only compatible with the walltime instrument.

feat(linter): add schema for simple rule configurations ( #22948 )
...
I asked AI to remove rules from the list which has the configuration syntax like:
```
serde_json::from_value::<XConfig<Self>>(value).map(XConfig::into_inner)
```
This pattern is safe to remove, because the right config is already auto generated.
Part of the command:

feat(linter): add right schema for eslint/max-* rules ( #22923 )
...
Adds richer JSON-schema/TypeScript typing for ESLint `max-*` rule configurations so oxlint’s published configuration schema (and the website snapshot) can validate and document these rules more accurately.

feat(linter): fill schema with rule configurations ( #22907 )
...
This PR is a proof-of-concept to enrich the generated Oxlint configuration JSON schema (and corresponding generated TS types) with per-rule configuration shapes instead of defaulting everything to `DummyRule`, while temporarily skipping rules whose schema generation hasn’t been validated.
The 3 rules are new and do not get skipped. (I generated the list from an old commit), verified that the generated output is the expected user configuration for each rule.
All other rules are skipped and will be enabled in future PRs.

refactor(semantic): add SemanticBuilder::new_compiler / new_linter presets ( #23019 )
...
## Summary
Adds two named constructor presets to `SemanticBuilder` that bake in the options each use case needs, so the configuration lives in one place instead of being repeated at call sites:
- **`SemanticBuilder::new_compiler()`** — compiler pipeline. Enables syntax-error checking; leaves linter-only analyses (control flow graph, class table) off.
- **`SemanticBuilder::new_linter()`** — linter. Enables syntax-error checking, the control flow graph, and the class table.
The presets are applied at the real pipeline entry points:
- `new_linter()` → the linter service build.
- `new_compiler()` → `oxc::Compiler`, and the napi parser/transform bindings.
Everywhere else keeps `SemanticBuilder::new()` and turns on only the features it needs (mangler, minifier, formatter, transformer plugins, examples, tests, ...). Individual options can still be overridden after a preset (e.g. the linter service overrides `check_syntax_error` with its runtime flag).
Behavior is preserved at every migrated site. Node-store access is intentionally untouched in this PR.
## Verified
- Builds across the affected crates + napi; clippy clean; `oxc_linter` tests pass; full `cargo coverage` with no snapshot changes.

fix(linter/plugins): make spreading Token instances keep loc property ( #22947 )
...
Follow-up of #22238 , same logic applied to `Token` class
## Problem
`Token` instances are object-pooled and reused across files, similar to
`Comment`.
Their `loc` property is defined as a **prototype getter**, which means
it is not an own
property and is therefore invisible to the spread operator:
```js
const spread = { ...token };
"loc" in spread; // false ❌
```
This silently drops `loc` whenever a JS plugin (or rule) spreads a token
— e.g. when
building a diagnostic from `{ ...token, message: "…" }`.
`JSON.stringify` had the same problem and was patched with a `toJSON()`
workaround.
A separate `Object.defineProperty(Token.prototype, "loc", { enumerable:
true })` call
was used to make `loc` show up in `for…in` iteration, but it still
didn't fix spread.
## Fix
Define `loc` as an own accessor property on every `Token` instance using
`__defineGetter__`. Own properties are visible to spread,
`JSON.stringify,` and
`for…in` iteration, so all three work without any extra workarounds.
The getter function is defined in the class static block and captured in
a `const`
(`getTokenLoc`). Using a `const` rather than a `let` lets V8 skip
reassignment checks
at the `defineGetter(this, "loc", getTokenLoc)` call site — a pattern
already
established in the codebase for `resetLoc`.
As a result:
- `toJSON()` is removed — `JSON.stringify` now works via the own
property directly.
- `Object.defineProperty(Token.prototype, "loc", { enumerable: true })`
is removed —
no longer needed.
## Test
A spread assertion is added to the existing `tokens` fixture:
```js
const spread = { ...firstToken };
assert("loc" in spread); // was false before this fix
assert.deepEqual(spread.loc, firstToken.loc);
```

fix(linter/plugins): make spreading Comment instances keep loc property ( #22238 )
...
## Summary: Fixing unicorn/expiring-todo-comments via jsPlugin
## Problem
The `unicorn/expiring-todo-comments` rule failed when run through
oxlint's jsPlugin system with error:
```TypeError: Either `node` or `loc` is required```
The rule spreads Comment instances (`{...comment}`) to process each line of multi-line comments, but lost the `loc` property because:
- Comment's `loc` was a prototype getter (not an own enumerable property)
- Spread only copies own enumerable properties
## Solution
Define `loc` as an own accessor property on every `Comment` instance using
`__defineGetter__`. Own properties are visible to spread, `JSON.stringify,` and
`for…in` iteration, so all three work without any extra workarounds.
The getter function is defined in the class static block and captured in a `const`
(`getCommentLoc`). Using a `const` rather than a `let` lets V8 skip reassignment checks
at the `defineGetter(this, "loc", getCommentLoc)` call site — a pattern already
established in the codebase for `resetCommentLoc`.
As a result:
- `toJSON()` is removed — `JSON.stringify` now works via the own property directly.
- `Object.defineProperty(Comment.prototype, "loc", { enumerable: true })` is removed —
no longer needed.
## Test Results
- ✅ unicorn/expiring-todo-comments rule works (detects expired TODOs)
- ✅ updated comments fixture pass
- ✅ All untouched existing tests pass

docs(oxfmt): annotate each config option with supported languages ( #22953 )

refactor(formatter_core): purify core and define rules ( #22952 )
...
The Printer never consumes these; they belong with each language formatter.
- Evict `Quote` (each formatter owns `QuoteStyle`)
- `normalize_string` takes a quote byte
- Evict `Expand` / `BracketSpacing` / `TrailingCommas` into oxc_formatter and oxc_formatter_json
- JSON's `TrailingCommas` is now two-variant (`Always`/`Never`)
- collapse Prettier's `all`/`es5` at each translation layer
- Rename `util/` -> `spec/` (pure shared helpers)
- Split `SourceText`: mechanical access stays in core, JS/TS lexis moves to `SourceTextExt`
- Drop the `oxc_syntax` dependency from core
All behaviros, Prettier conformance are unchanged.

perf(linter/plugins): create global prop vars at top level of modules ( #22928 )
...
Oxlint's JS-side code is processed by a TSDown plugin that transforms global property accesses to `const`s imported from `globals.ts`. e.g.:
```js
function foo(obj) {
return Object.keys(obj);
}
```
is transformed to:
```js
import { ObjectKeys } from "./utils/globals.ts";
function foo(obj) {
return ObjectKeys(obj);
}
```
The purpose of this transform is:
1\. Better perf - avoid a property lookup/check on each call.
2\. More robust in the face of user code (plugins) altering globals e.g. `Object.keys = function myWeirdFunction() {}`.
While delving into the assembly that V8 produces while reviewing #22238 , I discovered that in fact the transform was having a _negative_ effect on perf, because TSDown puts the global `const`s in a separate chunk `global.js`. Because the consts are in a different module, this actually makes them _more_ costly to access, rather than less.
In fact, it turns out that TurboFan doesn't insert a check at all in the original code - it instead has machinery to trigger de-opt if the global is reassigned. So the original perf rationale for this transform was completely misguided - it doesn't in fact produce a perf gain at all! We still want to keep it for the robustness advantage, but we don't want it to be perf _loss_, as it was before this PR.
This PR fixes the perf by instead defining consts inline in each file. The example above is now transformed to:
```js
const ObjectKeys = Object.keys;
function foo(obj) {
return ObjectKeys(obj);
}
```
This also removes the need to manually maintain the `globals.ts` file. It's now automatic.
Additionally, improve the transform in a few minor ways:
1. Support deeper nested global props e.g. `Object.prototype.toString`.
2. Skip converting e.g. `Array.prototype.slice.call(arguments)` (because `.call` requires `this`, so `ArrayPrototypeSliceCall(arguments)` is incorrect).
3. Do replace methods which take `this` (e.g. `Promise.resolve`) when they're not used in a method call.
Note: The robustness advantage of this transform may appear to be marginal, and not worth the bother of having this transform at all. Personally, I think it's worthwhile. Oxlint JS-side code has access to a slice of Rust's memory as a `Uint8Array`. Writing to that buffer could cause UB, reading/writing out of bounds, or other serious problems on Rust side, so IMO it's critical to protect against that in every way we can.

perf(linter/plugins): define class #loc setter functions as consts ( #22919 )
...
Micro-optimization.`Token` and `Comment` classes create functions defined in static blocks to reset the value of `#loc` private property on class instances. Copy these functions into `const` vars, to avoid checks at these functions' call sites. Previously they were stored in `let` bindings, which incurs a check at each call site (because the value might have been re-assigned). The difference in Turbofan-optimized code is just an 8-byte load and a comparison, but why keep that when we can lose it?
Discovered the perf difference while digging into #22238 .
