What is it?
ts-morph provides a higher-level interface over the TypeScript Compiler API, making it easier to navigate syntax trees, inspect types and symbols, and manipulate source code programmatically. It is aimed at tools that generate, refactor, or analyze TypeScript and JavaScript projects.
The repository is a monorepo. The main ts-morph package is the Compiler API wrapper, and @ts-morph/bootstrap is a separate library for setting up the Compiler API quickly.
The project is written in TypeScript and is distributed under the MIT license. It also links to a TypeScript AST Viewer website for exploring syntax trees.
Key features
- 01Navigate and inspect TypeScript and JavaScript syntax trees with a simpler API.
- 02Read types and symbols from source files.
- 03Make programmatic code changes such as adding or modifying declarations.
- 04Provide a separate bootstrap package for quick Compiler API setup.
Use cases
- Building code generators that emit TypeScript files.
- Writing refactoring or migration scripts for large codebases.
- Running static analysis checks on TypeScript projects.
