### Browserify integration
protobuf.js integrates into any browserify build-process. There are a few possible tweaks:
* If performance is a concern or IE8 support is required, you should make sure to exclude the browserified `buffer` module and let protobuf.js do its thing with Uint8Array/Array instead.
* If you do not need int64 support, you can exclude the `long` module.
* If your application does not rely on the following modules and/or package size is a concern, you can also exclude `process` , `_process` and `fs`.
* If you have any special requirements, there is [the bundler](https://github.com/dcodeIO/protobuf.js/blob/master/scripts/bundle.js) as a reference.
