Oxc ESTree

ESTree compatibility layer for serialization and interoperability.

Overview

This crate provides compatibility with the ESTree AST specification, primarily for serialization purposes. It enables oxc AST nodes to be serialized to and from JSON in ESTree format, facilitating interoperability with other JavaScript tools.

Key Features

ESTree compatibility: Convert oxc AST to/from standard ESTree format
Serialization support: JSON serialization/deserialization via serde
Tool interoperability: Enable integration with ESTree-based tools
Optional feature: Only enabled when serialize feature is active

Usage

Architecture

ESTree Specification

ESTree is a community standard for representing JavaScript AST nodes. This crate ensures oxc's AST can be represented in this standard format while maintaining compatibility with the broader JavaScript tooling ecosystem.

Design Principles

Compatibility: Full compatibility with ESTree specification
Optional overhead: Only included when serialization is needed
Type safety: Maintains Rust's type safety during conversion
Performance: Efficient serialization with minimal overhead

Use Cases

IDE integration: Language servers communicating via JSON
Tool interoperability: Working with Babel, ESLint, and other ESTree tools
Data exchange: Transferring AST data between different systems
Debugging: Human-readable AST representation

When the serialize feature is disabled, this crate provides only a placeholder trait to support derive macros without overhead.
