Book API

Docker

Launches the app and database containers. The database and tables will be created and seeded with example data, including an admin with the username admin and the password Adminl#1. These admin credentials should be passed as the Basic Auth Header to the /users/token endpoint in order to retrieve the login token. The login token should then be used as the Bearer Token for all other endpoints.

Make sure the .env file is loaded using godotenv.Load().

The following commands must be run from inside the project root:

Run

docker-compose up

Run in background

docker-compose up -d

Stop

docker-compose down

If you need to make changes to the app (e.g. to the .env file) you can stop the process using

docker-compose down --remove-orphans --volumes

... then rebuild using

docker-compose up --build

Local

To run locally (without Docker):

1. Create a local Postgres database
2. Change the settings in the .env file to match the local database
3. Make sure the .env file is loaded as godotenv.Load("../../.env")
4. From insise the cmd/book-api directory run: go run main.go

The database tables will created and seeded with example data, including an admin with the username admin and the password Adminl#1. These admin credentials should be passed as the Basic Auth Header to the /users/token endpoint in order to retrieve the login token. The login token should then be used as the Bearer Token for all other endpoints.
