Astring is a tiny, fast, dependency-free JavaScript code generator that produces JavaScript source code from ESTree-compliant ASTs. It supports modern ECMAScript up to ES2024 and stage 3 proposals, with optional source map and comment generation.

Use cases

• generate JavaScript code from an AST
• print an ESTree AST back to source code
• build a custom JavaScript transpiler or codemod
• regenerate code after AST transformations
• fast codegen alternative to Babel or Escodegen
• generate source maps for generated JavaScript

When to choose

• you need a small, fast, dependency-free code generator for ESTree ASTs
• you are building a transpiler, minifier, or codemod tool on top of Acorn or Meriyah
• performance matters more than pretty-printed formatting

When to avoid

• you need formatted or style-preserving output like Prettier
• you need to parse JavaScript rather than generate it
• you need to generate code for other languages
