esprima
A high-performance, standard-compliant ECMAScript parser for lexical and syntactic analysis.
What is esprima?
Esprima is a high-performance, standard-compliant ECMAScript parser written in JavaScript. It enables lexical analysis (tokenization) and syntactic analysis (parsing) of JavaScript code, producing a standardized abstract syntax tree (AST) for further processing. It solves the need for a reliable, fast parser to build tools like linters, compilers, and code transformers.
JavaScript tooling developers, library authors, and engineers building code analysis, transformation, or validation tools that require parsing JavaScript or JSX.
Developers choose Esprima for its strict ECMAScript standard compliance, high performance, and adoption of the ESTree AST format, ensuring interoperability and reliability. Its extensive testing and experimental JSX support make it a robust choice for modern JavaScript tooling.
