| # vm-browserify |
| |
| emulate node's vm module for the browser |
| |
| [](https://travis-ci.org/browserify/vm-browserify) |
| |
| # example |
| |
| Just write some client-side javascript: |
| |
| ``` js |
| var vm = require('vm'); |
| |
| $(function () { |
| var res = vm.runInNewContext('a + 5', { a : 100 }); |
| $('#res').text(res); |
| }); |
| ``` |
| |
| compile it with [browserify](http://github.com/substack/node-browserify): |
| |
| ``` |
| browserify entry.js -o bundle.js |
| ``` |
| |
| then whip up some html: |
| |
| ``` html |
| <html> |
| <head> |
| <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> |
| <script src="/bundle.js"></script> |
| </head> |
| <body> |
| result = <span id="res"></span> |
| </body> |
| </html> |
| ``` |
| |
| and when you load the page you should see: |
| |
| ``` |
| result = 105 |
| ``` |
| |
| # methods |
| |
| ## vm.runInNewContext(code, context={}) |
| |
| Evaluate some `code` in a new iframe with a `context`. |
| |
| Contexts are like wrapping your code in a `with()` except slightly less terrible |
| because the code is sandboxed into a new iframe. |
| |
| # install |
| |
| This module is depended upon by browserify, so you should just be able to |
| `require('vm')` and it will just work. However if you want to use this module |
| directly you can install it with [npm](http://npmjs.org): |
| |
| ``` |
| npm install vm-browserify |
| ``` |
