## What it is
ts-morph is a TypeScript library that wraps the TypeScript Compiler API to simplify programmatic navigation and manipulation of TypeScript and JavaScript code. It provides an easier interface for static analysis, AST traversal, and automated code changes.

## Use cases
- write codemods that refactor TypeScript code automatically
- analyze TypeScript source files and query the AST
- generate TypeScript code programmatically
- build custom linters or static analysis tools
- rename or move symbols across a codebase
- extract type information from source files

## When to choose
- you need to programmatically edit or generate TypeScript/JavaScript code
- the raw TypeScript Compiler API feels too low-level and verbose
- you're building code analysis, refactoring, or migration tooling

## When to avoid
- you only need to transpile or type-check code without AST manipulation
- you're working with languages other than TypeScript/JavaScript
- you need runtime code instrumentation rather than static analysis

## Facets
- artifact type: library
- maturity: active
- function: parser, developer-tools, code-review
- domain: developer-tools, parsers, programming-languages
- platform: cross-platform
- tags: typescript-compiler-api, ast-manipulation, code-generation, static-analysis, codemod, nodejs, deno
