I don&#x27;t understand why so many people use Gulp and file-system watchers during development. You have a web server, why not use it?<p>In our apps, when you request &#x2F;app.js or &#x2F;app.css or whatever, it goes through the tools (Browserify and SASS in our case) and delivers the transpiled versions on the fly.<p>We use a little NPM package called Staticr [1] to declare the pipelines so that the on-the-fly version used during development is identical to the production-time one. In production, we simply run Staticr against the pipelines, which produces the necessary minified files.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;bjoerge&#x2F;staticr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bjoerge&#x2F;staticr</a>
