<p>Escodegen (<a href="http://github.com/estools/escodegen">escodegen</a>) is an</p>
<p><a href="http://www.ecma-international.org/publications/standards/Ecma-262.htm">ECMAScript</a></p>
<p>(also popularly known as <a href="http://en.wikipedia.org/wiki/JavaScript">JavaScript</a>)</p>
<p>code generator from <a href="https://developer.mozilla.org/en/SpiderMonkey/Parser_API">Mozilla's Parser API</a></p>
<p>AST. See the <a href="https://estools.github.io/escodegen/demo/index.html">online generator</a></p>
<p>for a demo.</p>

<h4>Install</h4>

<p>Escodegen can be used in a web browser:</p>

<p> <script src="escodegen.browser.js"></script></p>

<p>escodegen.browser.js can be found in tagged revisions on GitHub.</p>

<p>Or in a Node.js application via npm:</p>

<p> npm install escodegen</p>

<h4>Usage</h4>

<p>A simple example: the program</p>

<p> escodegen.generate({</p>
<p> type: 'BinaryExpression',</p>
<p> operator: '+',</p>
<p> left: { type: 'Literal', value: 40 },</p>
<p> right: { type: 'Literal', value: 2 }</p>
<p> });</p>

<p>produces the string <code>'40 + 2'</code>.</p>

<p>See the <a href="https://github.com/estools/escodegen/wiki/API">API page</a> for</p>
<p>options. To run the tests, execute <code>npm test</code> in the root directory.</p>

<h4>Building browser bundle / minified browser bundle</h4>

<p>At first, execute <code>npm install</code> to install the all dev dependencies.</p>
<p>After that,</p>

<p> npm run-script build</p>

<p>will generate <code>escodegen.browser.js</code>, which can be used in browser environments.</p>

<p>And,</p>

<p> npm run-script build-min</p>

<p>will generate the minified file <code>escodegen.browser.min.js</code>.</p>
