TypeScript Sample Application

This repository provides a simple starting point for running TypeScript applications on OpenShift. It can also be applied to applications that use Babel or other transpilers.

A blogpost that runs through the details of this repository and OpenShift can be found here.

You can use this repository as a template, just click the green "Use this template" button at the top of this page on GitHub.

Running on OpenShift via NodeShift

To use this method of deployment you'll need:

NodeShift is a neat CLI that simplifies deployment of Node.js applications on OpenShift. This project incldues NodeShift in devDependencies.

You can run the following to deploy it on an OpenShift instance:

$ git clone git@github.com:evanshortiss/openshift-typescript-example.git ts-openshift

$ cd ts-openshift

# Ensure you are logged into your openshift instance
$ oc login

# Choose the project you'd like to deploy this applicaion into
$ oc new-project ts-example

# Build, deploy, and expose an endpoint for the service
$ npm run nodeshift -- --expose

If you're deploying on a locally running instance of OpenShift you might need to do the following to bypass the self-signed certificate issues:

$ npm run nodeshift -- --expose --strictSSL=false

Run Locally without Docker

To run this application locally you'll need:

  • Node.js v12 or later
  • npm v6 or later
  • Git

Execute the following commands to start the program locally:

git clone git@github.com:evanshortiss/openshift-typescript-example.git ts-openshift

cd ts-openshift

npm instal
npm run build
npm start

If you're developing locally, start a live reload server like so:

npm run start-dev

Build Locally using Source-to-Image (s2i)

To perform the following steps you'll need:

With both tools installed, execute the following commands to run your application locally. This will create a container that matches the one created using an OpenShift Build.

# Run the s2i build script
./scripts/s2i.sh

# Run the container image
docker run -p 8080:8080 quay.io/evanshortiss/openshift-s2i-typescript-example

Running Local Dev Mode using Docker Compose

To perform the following steps you'll need:

Run the docker-compose up command from the root of the repository to start Node.js and Redis containers.

The application will be available on port 8080.
