| |
| 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`. |
