Overview

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:

> var esprima = require('esprima');
> var program = 'const answer = 42';

> esprima.tokenize(program);
[ { type: 'Keyword', value: 'const' },
  { type: 'Identifier', value: 'answer' },
  { type: 'Punctuator', value: '=' },
  { type: 'Numeric', value: '42' } ]
  
> esprima.parseScript(program);
{ type: 'Program',
  body:
   [ { type: 'VariableDeclaration',
       declarations: [Object],
       kind: 'const' } ],
  sourceType: 'script' }

For more information, please read the complete documentation.

Changed npmignore to add the whole test directory and remove innecessary directories

The test directory isn't needed at all when installed this package as a dependency and are 8MB we could save from network and disk. Also the .git directory is ignored by default, so there's no need to add it.

SOS esprima 404 error

Hi @ariya how are you? I'm sorry for opening this PR, but since I haven't found a place to post an issue with esprima, it was the only way I found to post this problem.

I'm trying to install all dependencies in my react project, but when I run npm install I'm getting some errors related to esprima:

npm ERR! 404 Not Found - GET https://codeload.github.com/ariya/esprima/legacy.tar.gz/master npm ERR! npm ERR! 404 npm ERR! npm ERR! 404 'esprima@https://github.com/ariya/esprima/tarball/master' is not in the npm registry. npm ERR! npm ERR! 404 You should bug the author to publish it (or use the name yourself!) npm ERR! npm ERR! 404 npm ERR! npm ERR! 404 Note that you can also install from a npm ERR! npm ERR! 404 tarball, folder, http url, or git url.

Can you please help me with this error?
