 <p>I am not really sure what you mean by integrating bootstrap with Meanjs, according to me it is already integrated in the default app. If you go to <code>config/assets/default.js</code> and <code>config/assets/production.js</code> (one is for development and the other for production) under <code>client.lib.css</code> and <code>client.lib.js</code> the bootstrap modules are specified. These modules are loaded in <code>modules/core/server/views/layout.server.view.html</code> just under the comments <code>&lt;!-- Application CSS Files --&gt;</code> and <code>&lt;!--Application JavaScript Files--&gt;</code> when the application starts.</p> <p>If you want to upgrade to the latest Bootstrap just change the version number in your <code>bower.json</code> file and run the command <code>bower update</code>. </p>
