NOTE

This fork/clone of esprima tracks the original closely, but adds support for parsing JISON action code blocks, which MAY contain JISON-specific identifiers in the JavaScript code, e.g. $1, @1, #1 and #ID#.

Esprima (esprima.org, BSD license) is a high performance, standard-compliant ECMAScript parser written in ECMAScript (also popularly known as JavaScript). Esprima is created and maintained by Ariya Hidayat, with the help of many contributors.

Features

Full support for ECMAScript 2017 (ECMA-262 8th Edition)
Sensible syntax tree format as standardized by ESTree project
Experimental support for JSX, a syntax extension for React
Optional tracking of syntax node location (index-based and line-column)
Heavily tested (~1500 unit tests with full code coverage)

API

Esprima can be used to perform lexical analysis (tokenization) or syntactic analysis (parsing) of a JavaScript program.

A simple example on Node.js REPL:

1> var esprima = require('esprima');
2> var program = 'const answer = 42';
3
4> esprima.tokenize(program);
5[ { type: 'Keyword', value: 'const' },
6  { type: 'Identifier', value: 'answer' },
7  { type: 'Punctuator', value: '=' },
8  { type: 'Numeric', value: '42' } ]
9  
10> esprima.parse(program);
11{ type: 'Program',
12  body:
13   [ { type: 'VariableDeclaration',
14       declarations: [Object],
15       kind: 'const' } ],
16  sourceType: 'script' }
