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`.
