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 app contains an opinionated set of components for modern web development, including:
You can deploy this application to IBM Cloud or build it locally by cloning this repo first. Once your app is live, you can access the /health endpoint to build out your cloud native application.
Click Deploy to IBM Cloud to deploy this same application to IBM Cloud. This option creates a deployment pipeline, complete with a hosted GitLab project and a DevOps toolchain. You can deploy your app to Cloud Foundry, a Kubernetes cluster, or a Red Hat OpenShift cluster. OpenShift is available only through a standard cluster, which requires you to have a billable account.
IBM Cloud DevOps services provides toolchains as a set of tool integrations that support development, deployment, and operations tasks inside IBM Cloud.
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 10+ LTS version.
Once the Node toolchain has been installed, you can download the project dependencies with:
npm installModern 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.
To run your application locally:
npm run startYour application will be running at http://localhost:3000. You can access the /health endpoint at the host.
Install IBM Cloud Developer Tools on your machine by running the following command:
curl -sL https://ibm.biz/idt-installer | bash
Create an application on IBM Cloud by running:
ibmcloud dev createThis will create and download a starter application with the necessary files needed for local development and deployment.
Your application will be compiled with Docker containers. To compile and run your app, run:
ibmcloud dev build
ibmcloud dev runThis will launch your application locally. When you are ready to deploy to IBM Cloud on Cloud Foundry or Kubernetes, run one of the following commands:
ibmcloud dev deploy -t buildpack // to Cloud Foundry
ibmcloud dev deploy -t container // to K8s clusterYou can build and debug your app locally with:
ibmcloud dev build --debug
ibmcloud dev debugYou 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.
