Escodegen is an ECMAScript (JavaScript) code generator that produces JavaScript source code from ESTree/Mozilla Parser API abstract syntax trees. It runs in Node.js and browsers and is part of the estools tooling ecosystem.
Use cases
- generate JavaScript source code from an AST
- implement a transpiler or code transformer
- pretty-print ESTree ASTs back into JS
- build code generation tools for linters or codemods
- emit JS code programmatically in a browser
When to choose
- you have an ESTree AST and need to emit JavaScript source
- you are building transpilers, codemods, or AST-based code tools
- you need a mature, widely used JS code generator with browser support
When to avoid
- you need to parse JavaScript rather than generate it
- you need generation for non-JavaScript languages
- you need actively developed support for the newest ECMAScript syntax
