Node application that proxies requests to NASA's Astronomy Picture Of the Day API and caches responses using Redis.

An API key for api.nasa.gov is required. A key can be generated in about 5 seconds at: https://api.nasa.gov/#signUp

Redis is running inside docker.

Start up redis using docker-compose:

docker-compose up

To run the server on port 3000:

NASA_API_KEY=<nasa-api-key-here> npm start

Hit the root endpoint with or without a date. Any request made with a date will have its response cached for 60 minutes.

curl http:https://localhost:3000/?date=2019-10-28

To deploy to PCF, the following must be setup:

• A space with the following services available to bind:
  • Redis for PCF (https://network.pivotal.io/products/p-redis)
  • Credhub Service Broker (https://docs.pivotal.io/credhub-service-broker) configured with:
    • {"NASA_API_KEY":"<YOUR NASA API KEY>"
• After initial deploy, these services must be bound and the app re-staged

Deploy via:

./deploy.sh

Additionally, you can monitor the deploy using:

./monitor.sh

This is useful to make sure zero-downtime deployments are working as expected.
