# Browser Builds Bitcore and most official submodules work in the browser, thanks to [browserify](http://browserify.org/) (some modules are not fully compatible with web browsers). The easiest and recommended way to use them, is via [Bower](http://bower.io/), a browser package manager, and get the release bundles. For example, when building an app that uses `bitcore` and `bitcore-mnemonic`, you do: ```sh bower install bitcore-lib bower install bitcore-mnemonic ``` You can also use a `bower.json` file to store the dependencies of your project: ```json { "name": "Your app name", "version": "0.0.1", "license": "MIT", "dependencies": { "bitcore-lib": "^0.13.7", "bitcore-mnemonic": "^1.0.1" } } ``` and run `bower install` to install the dependencies. After this, you can include the bundled release versions in your HTML file: ```html ``` ## Building Custom Bundles If you want to use a specific version of a module, instead of a release version (not recommended), you must run browserify yourself. You can get a minified browser bundle by running the following on the project root folder. ```sh browserify --require ./index.js:bitcore-lib | uglifyjs > bitcore-lib.min.js ``` ```sh browserify --require ./index.js:bitcore-mnemonic --external bitcore-lib | uglifyjs > bitcore-mnemonic.min.js ``` In many of the modules you can also run the command to build a browser bundle: ```sh gulp browser ```
