title: How to deploy NextJs (SSR) using "Output File Tracing" feature to Azure App Service?
body: <p>I have deployed my Next.js project to the Azure App service that needs to include &quot;node_modules&quot; to run the production (&quot;npm start&quot;).</p>
  <p>But.. I found that the &quot;node_modules&quot; size is so big (354,3 MB on disk).</p>
  <p>And then I saw that we could use the <a href="https://nextjs.org/docs/advanced-features/output-file-tracing" rel="nofollow noreferrer">&quot;Output File Tracing&quot;</a> feature to reduce the size of deployments drastically.</p>
  <p>So how can I use that feature? I think that will affect my Azure Pipeline and Release</p>
