Quarkus RESt API example

This project uses Quarkus to build REST APIs.

For the tutorials check the below links,

• Secure REST APIs in Quarkus using Basic Auth

Running the application in dev mode

First start the docker:

$ cd docker && docker-compose up -d

Then create tables with some predefined data,

$ ./db_initializer.sh

Finally, you can run your application in dev mode that enables live coding using:

$ ./mvnw quarkus:dev

Interacting with APIs

The app runs on localhost:8080. You can interact with the APIs via Swagger localhost:8080/swagger-ui

Alternatively you can use CURL as follows,

# get list of users (secured, accessible to users with 'ADMIN' or 'USER' role)
$ curl --anyauth --user leo:1234 localhost:8080/v1/users/

# get a specific user (secured, accessible to users with 'ADMIN' or 'USER' role)
$ curl --anyauth --user leo:1234 localhost:8080/v1/users/2

# create a user (open)
$ curl --request POST 'localhost:8080/v1/users' --header 'Content-Type: application/json' \
--data-raw '{
	"firstName": "Tom",
	"lastName": "Cruise",
	"age": 57
}'

# edit a user (secured, accessible to users with 'ADMIN' role only)
$ curl --anyauth --user admin:admin --request PUT 'localhost:8080/v1/users/1' --header 'Content-Type: application/json' \
--data-raw '{
	"firstName": "Leonardo",
	"lastName": "DiCaprio",
	"age": 46
}'

# delete a user (secured, accessible to users with 'ADMIN' role only)
$ curl --anyauth --user admin:admin --request DELETE 'localhost:8080/v1/users/2'

Debugging the application

To debug the app, run the following command first,

$ ./mvnw quarkus:dev -Ddebug

This activates debug on port 5005. Then use your IDE to connect to localhost:5005 to debug the application.
