webpack/examples/require.resolve/README.md

Packs CommonJs/AMD modules for the browser. Allows to split your codebase into multiple bundles, which can be loaded on demand. Support loaders to preprocess files, i.e. json, jade, coffee, css, less, ... and your custom stuff.

# example.js

``` javascript
var a = require("./a");

// get module id
var aId = require.resolve("./a.js");

// clear module in require.cache
delete require.cache[aId];

// require module again, it should be reexecuted
var a2 = require("./a");

// vertify it
if(a == a2) throw new Error("Cache clear failed :(");
```

# a.js


``` javascript
module.exports = Math.random();
```
