[![npm version](https://badge.fury.io/js/escodegen.svg)](http://badge.fury.io/js/escodegen)
[![Build Status](https://secure.travis-ci.org/estools/escodegen.svg)](http://travis-ci.org/estools/escodegen)
[![Dependency Status](https://david-dm.org/estools/escodegen.svg)](https://david-dm.org/estools/escodegen)

Escodegen ([escodegen](http://github.com/estools/escodegen)) is an
[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
(also popularly known as [JavaScript](http://en.wikipedia.org/wiki/JavaScript))
code generator from [Mozilla's Parser API](https://developer.mozilla.org/en/SpiderMonkey/Parser_API)
AST. See the [online generator](https://estools.github.io/escodegen/demo/index.html)
for a demo.
### Install
Escodegen can be used in a web browser:
<script src="escodegen.browser.js"></script>
escodegen.browser.js can be found in tagged revisions on GitHub.
Or in a Node.js application via npm:
npm install escodegen
### Usage
A simple example: the program
escodegen.generate({
type: 'BinaryExpression',
operator: '+',
left: { type: 'Literal', value: 40 },
right: { type: 'Literal', value: 2 }
});
produces the string `'40 + 2'`.
See the [API page](https://github.com/estools/escodegen/wiki/API) for
options. To run the tests, execute `npm test` in the root directory.
### Building browser bundle / minified browser bundle
At first, execute `npm install` to install the all dev dependencies.
After that,
npm run-script build
will generate `escodegen.browser.js`, which can be used in browser environments.
And,
npm run-script build-min
will generate the minified file `escodegen.browser.min.js`.
