Example CRUD Application

First, install the dependencies

npm install

A Postgres DB is needed, so if you are using Docker, then you can start a postgres db easily.

docker run --name os-postgres-db -e POSTGRESQL_USER=luke -e POSTGRESQL_PASSWORD=secret -e POSTGRESQL_DATABASE=my_data -d -p 5432:5432 centos/postgresql-10-centos7

In this example, the db user is luke, the password is secret and the database is my_data

You can then start the application like this:

DB_USERNAME=luke DB_PASSWORD=secret ./bin/www

Then go to http://localhost:8080

Other options:

• npm run dev same as npm start but with pretty output log.
• npm run dev:debug shows debug information.

First, make sure you have an instance of Openshift setup and are logged in using oc login.

Then create a new project using the oc commands

oc new-project fun-node-fun

For this example, you will also need a postgres db running on your Openshift cluster.

oc new-app -e POSTGRESQL_USER=luke -ePOSTGRESQL_PASSWORD=secret -ePOSTGRESQL_DATABASE=my_data centos/postgresql-10-centos7 --name=my-database

Then run npm run openshift to deploy your app

Run the following command to show the newly exposed route that you can navigate:

oc get route nodejs-rest-http-crud
NAME                    HOST/PORT                                        PATH   SERVICES                PORT   TERMINATION   WILDCARD
nodejs-rest-http-crud   nodejs-rest-http-crud-opentel.apps-crc.testing          nodejs-rest-http-crud   8080                 None
