Esprima is a high-performance, standard-compliant ECMAScript (JavaScript) parser written in TypeScript/JavaScript, producing ESTree-format ASTs and supporting tokenization. It supports ECMAScript 2019 with experimental JSX support and optional node location tracking.
Use cases
- parse javascript source code into an ast
- tokenize js code for lexical analysis
- build a javascript linter or static analysis tool
- transform or rewrite javascript code via its syntax tree
- analyze jsx syntax in react code
- extract code structure for autocomplete or visualization
When to choose
- you need a mature, heavily tested, standard-compliant JS parser with ESTree output
- you need tokenization as well as parsing
- you need node location info (line-column and index)
- your target is ECMAScript 2019 or earlier
When to avoid
- you need support for the latest ECMAScript features beyond ES2019
- you need robust JSX or TypeScript parsing in production
- you want an actively evolving parser with frequent updates
