React is a popular framework for creating user interfaces in modular components. In this sample application, you will create a web application using Express and React to serve web pages in Node.js, complete with standard best practices, including a health check and application metric monitoring.
This code pattern contains 12 popular UI patterns that make it very easy to construct a dashboard application.
This app contains an opinionated set of components for modern web development, including:
After you have created a new git repo from this git template, remember to rename the project.
Edit package.json and change the default name to the name you used to create the template.
Make sure you are logged into the IBM Cloud using the IBM Cloud CLI and have access to you development cluster. If you are using OpenShift make sure you have logged into OpenShift CLI on the command line.
npm i -g @garage-catalyst/ibm-garage-cloud-cli
Use the IBM Garage for Cloud CLI to register the GIT Repo with Jenkins
igc register
To get started building this application locally, you can either run the application natively or use the IBM Cloud Developer Tools for containerization and easy deployment to IBM Cloud.
Install the latest Node.js 6+ LTS version.
Once the Node toolchain has been installed, you can download the project dependencies with:
npm install
cd client; npm install; cd ..
npm run build
npm run startModern web applications require a compilation step to prepare your ES2015 JavaScript or Sass stylesheets into compressed Javascript ready for a browser. Webpack is used for bundling your JavaScript sources and styles into a bundle.js file that your index.html file can import.
Webpack
For development mode, use webpack -d to leave the sources uncompress and with the symbols intact.
For production mode, use webpack -p to compress and obfuscate your sources for development usage.
Gulp
Gulp is a task runner for JavaScript. You can run the above Webpack commands in by running:
gulpTo run your application locally:
npm run startYour application will be running at http://localhost:3000. You can access the /health and /appmetrics-dash endpoints at the host.
You may see this warning when running ibmcloud dev run:
Warning: connect.session() MemoryStore is not
designed for a production environment, as it will leak
memory, and will not scale past a single process.
When deploying to production, it is best practice to configure sessions to be stored in an external persistence service.
