The ESTree Spec is a community-maintained specification for the JavaScript AST (Abstract Syntax Tree) format originally produced by SpiderMonkey's parser API. It serves as the lingua franca standard that JavaScript parsing and code-manipulation tools like ESLint, Babel, and Acorn align to.

Use cases

• understand the AST node format produced by JavaScript parsers
• build a tool that manipulates JavaScript source code via ASTs
• check how a new JavaScript syntax feature should be represented as AST nodes
• implement a JavaScript parser compatible with the ESTree format
• write codemods or linters that traverse JavaScript syntax trees

When to choose

• you are building or using JavaScript parsing, linting, transpiling, or code-generation tools and need the canonical AST node definitions
• you want to propose or track how new ECMAScript syntax maps to AST structures

When to avoid

• you need an actual parser implementation rather than a specification document
• you need AST specs for languages other than JavaScript
