Oxc AST (Abstract Syntax Tree) Nodes

Supports JavaScript, TypeScript and JSX.

Types

AST types are similar to estree and typescript-eslint's definition, with a few notable exceptions:

• Identifier is replaced with explicit BindingIdentifier, IdentifierReference, IdentifierName, per ECMAScript Specification.
• AssignmentExpression.left Pattern is replaced with AssignmentTarget.
• Literal is replaced with BooleanLiteral, NumericLiteral, StringLiteral etc.

Field order of types follows "Evaluation order" defined by ECMAScript spec. For TypeScript types, we follow how field order is defined in tsc.

Oxc's visitors (Visit, VisitMut, Traverse) visit AST node fields in same order as they are defined in the types here.

Parsing

You can obtain an AST by parsing source code with a Parser from oxc_parser.
