TSQuery is a TypeScript library that ports the ESQuery API to TypeScript, letting you query a TypeScript AST using CSS-style selectors. It supports node type selectors, attribute matching, combinators, and pseudo-classes for pattern-based syntax matching.

Use cases

• find all identifiers named X in a TypeScript file
• query TypeScript AST with CSS-like selectors
• write custom lint rules that match syntax patterns
• search code for specific AST node patterns
• extract class declarations or function signatures from TypeScript source
• build codemods that select nodes to transform

When to choose

• you need pattern-based searching over TypeScript source code
• you're building linting, refactoring, or codemod tooling on the TypeScript compiler API
• you already know ESQuery or CSS selectors and want the same ergonomics for TS ASTs

When to avoid

• you need to query JavaScript or other languages' ASTs (use ESQuery or a language-specific tool)
• you need full TypeScript type information rather than syntax patterns
• you want a GUI-based code search tool
