Overview

Package tsparser implements processor.Processor for TypeScript and JavaScript source files (.ts, .tsx, .js, .jsx) using tree-sitter.

Mapping onto the language-neutral model: classes become Structs, interfaces and type aliases and enums become Interfaces (aliases carry their right-hand side in Alias), and both function declarations and consts initialized with a function become Functions. Exported means the symbol carries an `export` modifier or appears in an `export { ... }` / `export default` clause.

The per-file call records (Result.CallGraph) feed callgraph.Aggregate, the AST-only fallback tier: plain identifier calls, `new` expressions, and JSX elements with capitalized names (component renders) are recorded; member calls like api.log() are not, since without type information they are mostly external noise.

Functions

func BuildCallGraph

func BuildCallGraph(root string, relPaths []string) (*callgraph.CallGraph, error)

BuildCallGraph builds the module-wide TS/JS call graph for the given files (paths relative to root). It is the precise tier for TypeScript: imports are resolved per file (relative specifiers, barrel re-exports, tsconfig baseUrl/paths aliases), so calls, new-expressions, and JSX component renders connect to the declaration they actually reference, and calls into npm packages are counted as external dependencies — mirroring what the go/packages builder provides for Go, minus type inference: only identifier calls, this.method() calls, and member calls on imported names resolve; calls through arbitrary local variables do not.

Types

type Processor

type Processor struct{}

Processor implements processor.Processor for TypeScript/JavaScript files.

func (*Processor) Process

func (p *Processor) Process(ctx context.Context, path string, src []byte) (*processor.Result, error)

Process parses one file and extracts its API surface and call records. Plain .ts uses the typescript grammar (where `<T>expr` casts are legal); .tsx, .jsx, and .js use the tsx grammar, which accepts JSX.

func (*Processor) Supports

func (p *Processor) Supports(ext string) bool

Supports reports whether the file extension is handled by this processor.
