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`.
