pack_delivery_api

This is an API that uses the packages below to create an API:

• HTTP Router: https://github.com/go-chi/chi
• CORS checks: https://github.com/go-chi/cors
• Request id generation(KSUID): https://github.com/segmentio/ksuid
• Logging: https://github.com/sirupsen/logrus

Running the API

To be able to use postgres locally without SSL, comment the following lines of code in db/db.go:

	TLSConfig: &tls.Config{
		InsecureSkipVerify: true,
	},

This disables ssl connection with the postgres instance locally. It is used in the deployed version of the app to ensure communication with the DB is encrypted.

Exploring the API

To take a look at the API structure and try out endpoints, go to http://localhost:8080/api/v1/swagger/index.html

There are two options to run the API:

Using go cli commands

1. Make sure you have Postgres running
2. Add your env variables(check config/config.go) for db credentials
3. Run make migrate(this will run migrations and then run the server)
4. Go to localhost:8080 to access the API

Using Docker

1. Run docker-compose up. This will create two containers: one for the Postgres db, and another for the API.
2. Go to localhost:8080 to access the API

Running the tests

To run tests, run go test ./controllers ./services
