Inspiration API

An experimental API designed to improve my own skills at using both Scala and the Play Framework.

Running Locally

The service depends on the use of SBT and Docker.

Docker Setup

Launch a PSQL docker image exposed on port 5432

  • docker-compose up -d

Setup default tables automatically with provided script

  • psql -h localhost -U user inspiration_db -f dbsetup.sql

Note that the JDBC DB connection requires 2 env vars to be set:

  • DB_USER
  • DB_PASS

These will vary depending on your local postgres setup.

val connectionUrl = s"jdbc:postgresql://localhost:5432/inspiration_db?user=${sys.env("DB_USER")}&password=${sys.env("DB_PASS")}"

API Start

  • In one terminal run the command sbt run
  • In another terminal curl the inspiration endpoint: curl localhost:9000/inspiration

A basic html page is provided at the index route if you load up localhost:9000 in a browser you will see instructions for the available endpoints

Available Endpoints

GET

/inspiration - returns a single string containing a random quote featuring the author.

curl localhost:9000/inspiration

POST

/inspiration - adds post data to postgres DB - requires user to specify author and quote

curl -X POST -H 'Content-Type: application/json' -d '{"author": "dmcm", "quote": "quotation of the year"}' localhost:9000/inspiration

PUT

/inspiration - updates data in postgres DB - requires user to specify index, author and quote

curl -X PUT -H 'Content-Type: application/json' -d '{"index": 5, "author": "dmcm", "quote": "quotation of the year"}' localhost:9000/inspiration

DELETE

/inspiration/:index - deletes entry from postgres DB - requires user to specify index within url

curl -X DELETE localhost:9000/inspiration/6

Docker

The service can be run from a Docker container:

# build and tag image locally
docker build -t inspiration_api:v1 .

# port forwarding Docker to localhost:9000
docker run -ti -p 9000:9000 --network="host" <docker-image-id>

# publish docker image to docker hub
docker push <docker-repo>
