Use TypeScript to Build a Node API with Express
- Tutorial referenct at post: https://developer.okta.com/blog/2018/11/15/node-express-typescript
- Sign up for a free Okta Developer account
- You will get a URL similar to https://dev-123456.oktapreview.com.
- Save this URL for later
- You will also use this URL to login to your Okta account
- Create docker container postgres (ref blog post)
You will need to create an application in Okta:
- Log in to your Okta account, then navigate to Applications and click the Add Application button
- Select Web and click Next
- Give your application a name (e.g. "Simple Node Authentication")
- Change the Base URI to
http://localhost:3000and the Login redirect URI tohttp://localhost:3000/authorization-code/callback, then click Done - Save your client ID and client secret for later
Your Okta application should have settings similar to the following:
Now create a file called .env in the project root and add the following variables, replacing the values with your own from the previous steps.
# Set to production when deploying to production
NODE_ENV=development
# Node.js server configuration
SERVER_PORT=8080
HOST_URL=http://localhost:8080
SESSION_SECRET=[YOUR SECRET SESSION]
# Okta configuration
OKTA_ORG_URL=https://dev-228303.okta.com
OKTA_CLIENT_ID=[YOUR CLIENT ID]
OKTA_CLIENT_SECRET=[YOUR CLIENT SECRET]
# Postgres configuration
PGHOST=localhost
PGUSER=postgres
PGDATABASE=postgres
PGPASSWORD=p@ssw0rd42
PGPORT=5432
Now run the application:
npm install
npm run dev
