+# Node.js Component for Diploi
+
+A generic Node.js component that can be used to run any Node.js app.
+
+Uses the official [node](https://hub.docker.com/_/node) Docker image.
+
+## Operation
+
+### Development
+
+Will run `npm install` when component is first initialized, and `npm run dev` when deployment is started.
+
+### Production
+
+Will build a production ready image. Image runs `npm install` & `npm build` when being created. Once the image runs, `npm start` is called.
