Bitcore and most official submodules work in the browser, thanks to [browserify](http://browserify.org/) (some modules are not fully compatible with web browsers).
*Note:* You probably don't want to use this method, but `bitcore-build`, as explained above. This is left here as documentation on what happens under the hood with `bitcore-build`.
When developing a module that will depend on Bitcore, it's recommended to exclude Bitcore in the distributed browser bundle when using browserify and to use the `--external bitcore` parameter. It will produce a smaller browser bundle, as it will only include the JavaScript that is nessessary, and will depend on the Bitcore browser build which is better for distribution.
See the [main file](https://github.com/bitpay/bitcore/blob/master/index.js) for bitcore for a complete list, as well as the [Bitcore Documentation](index.md).
This will output a file `module-name.js` with only the code loaded from `index.js` (bitcore.js will need to be loaded beforehand, which is around 145KB gzipped)
