Example Node.js API using Express, TypeScript, Vue, and PostgreSQL

This example application shows how to create a Node.js Express web app using TypeScript. Please read Use TypeScript to Build a Node API with Express to see how this app was created.

Requirements

• Install Node.js version 8+
• Install Docker (or some other instance of PostgreSQL)

Development setup

• Clone or download this repository
• Install modules using npm install
• Copy .env.sample to .env
• Set up PostgreSQL with Docker. With docker installed, use the following two commands to create an instance of PostgreSQL for the application. Feel free to change the name and password for the database.

docker pull postgres:latest
docker run -d --name guitar-db -p 5432:5432 -e 'POSTGRES_PASSWORD=p@ssw0rd42' postgres

• Modify .env to match your PostgreSQL server connection and credentials

• Initialize the PostgreSQL database by running npm run initdb

• Create a free Okta Developer Account

• Set up a new Okta application

  1. In the Applications section, click "Add Application"
  2. Select "Web" and click Next
  3. Name your application, and set the Login Redirect URIs to http://localhost:8080/authorization-code/callback. By default, the web application will run locally at http://localhost:8080. Click Save.

• On the Application screen under the General tab you will find a section for "Client Credentials." You will need to copy the values for "Client ID" and "Client secret" and paste them into the .env file for OKTA_CLIENT_ID and OKTA_CLIENT_SECRET, respectively.

• Copy the URL for your Okta developer account (e.g. https://dev-123456-admin.oktapreview.com) and paste it into the .env file as the value for OKTA_ORG_URL. Remove -admin from the URL. The setting should look similar to:

OKTA_ORG_URL=https://dev-123456.oktapreview.com

Launching application

To run the application in development mode:

npm run dev

By default, the web application should now be running at http://localhost:8080.
