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 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.
