A JavaScript library for generating and consuming source maps, the standard format mapping generated code back to original sources. It provides both high-level (SourceNode) and low-level (SourceMapGenerator/SourceMapConsumer) APIs and works in Node.js and the browser.

Use cases

• generate source maps for a transpiler or minifier
• map stack trace positions back to original source files
• read and query mappings from an existing source map
• combine or transform source maps in a build tool
• embed original source content in generated source maps

When to choose

• you are building a compiler, bundler, or minifier that must emit source maps
• you need to resolve generated positions to original sources programmatically
• you need a battle-tested, widely-adopted source map implementation for Node or the browser

When to avoid

• you only need source map support inside an existing bundler that already provides it
• you need a language other than JavaScript/TypeScript ecosystem tooling
• you need source map generation for CSS-only or other specialized formats with dedicated tooling
