## Distribution
This library is implemented as a ES6 module and also distributed as a CommonJS module, UMD module and a compiled script for browsers. If your system does not pick one automatically for you, you can pick one in the **dist/** folder.
- The CommonJS is the one used by Node. It is served in the "main" field of this library's package.json
- The UMD module is compatible with Node, AMD and browsers. It is served in the "browser" field.
- The compiled dist is browser-only and should be the one served by CDNs.
- The "module" field points to "./index.js" and should be the default entry point.
This library is a ES6 module also distributed as a CommonJS module, UMD and a compiled script for browsers.
If you are using a module bundler to compile a module that depends on **endianness** you might need to specify what is the correct entry point as some bundlers will assume "browser". In general, you should point to "module".
- The **CommonJS** is the one used by Node. It is served in the "main" field of package.json
- The **UMD** module is compatible with Node, AMD and browsers. It is served in the "browser" field.
- The **compiled dist** is browser-only and should be the one served by CDNs.
- The **ES6** dist is **endianness.js**, served as "module" in package.json
### webpack example:
```javascript
module.exports = {
entry: './index.js',
resolve: {
// tells webpack to use 'module' or 'main'
// not 'browser'
mainFields: ['module', 'main']
},
...
};
```
You may load both **endianness.umd.js** and **endianness.min.js** in the browser with ```<script>``` tags.
