Dakar

Fully reactive online travel agency made with Spring Boot 2 (w/ WebFlux), Angular, GraphQL, CouchBase, Maven, CircleCI, and Docker.

The goal is to learn as much as possible about new tech while creating a small but hopefully helpful travel agency fully made in reactive programming.

Maven Central Repo

https://mvnrepository.com/artifact/com.dakar/dakar

Docker hub

https://hub.docker.com/repository/docker/dakarinternational/dakar

Github Release

https://github.com/DaKarInternational/DaKar/releases/tag/3.0.0

On way to launch the app

1. build jar
   mvnw clean install -DskipTests

2. build docker
   ./mvnw dockerfile:build

3. launch test db
   docker-compose up -d couchtest

4. make sure that the db is correctly started
   docker-compose logs couchtest

5. launch the app within your IDE
   mvnw spring-boot:run -Dspring.profiles.active=local

If you have some network issues with Docker, you may consider having a look at your hosts file
add couch-dakar in your /etc/hosts

Some test endpoints

Functional controller
http://localhost:8080/test5/

Functional controller :
http://localhost:8080/test1/afghanistan

Functional controller -> hateoas w/ assembler:
http://localhost:8080/test2/afghanistan

Functional controller -> hatoas w/ generics:
http://localhost:8080/test3/afghanistan

Functional controller -> GraphQL:
http://localhost:8080/graphql

Functional controller -> i18n:
http://dakar.lambla.eu:8080/welcome/fr/message
http://localhost:8080/welcome/fr/message

Couchbase:
http://localhost:8091/

Limitations

• Swagger with spring webflux
• GraphQL subscriptions with spring webflux

Some useful commands

Docker setup:

sudo systemctl start docker  
sudo usermod -a -G docker $USER  
sudo reboot  
docker pull dreaserdocker/dakar
docker-compose pull
docker login

List all images

docker images

Build the test couchbase image independently of the rest using docker

docker build -f Dockerfile.testdb . -t testdb

Build and launch the couchbase using docker-compose

docker-compose up -d couch // to launch only the db

Launch all docker-compose services

docker-compose up

To launch the db

Either you launch a new container with a couchbase and do all that

create cluster
create bucket named 'test'
create index

CREATE PRIMARY INDEX ON `test`  

create user 'test' with password = 'password'

Or you just

docker-compose up -d couchtest  

docker-compose stop couchtest  

docker exec -ti couch-test /bin/bash  
tail -f /opt/couchbase/var/lib/couchbase/logs/http_access_internal.log  

Or

docker-compose -f docker-compose-prod.yml exec couch bash

docker image prune
docker volume prune
docker-compose -f docker-compose-prod.yml rm -v

Generate the javadoc

./mvnw javadoc:javadoc

Maven deploy

./mvnw clean package source:jar javadoc:jar deploy

Maven build and push the docker

./mvnw dockerfile:build dockerfile:push 

List all containers

docker-compose ps  
docker ps --all

Delete all containers

docker rm $(docker ps -a -q)

Delete all images

docker rmi $(docker images -q)

Some examples of GraphQl queries

// all jouneys  
query {
    allJourney{
        destination
    }
}

// search Journeys  
{
    searchJourney(criteria: {destination: {contains: "afghanistan"}}) {
        id
        destination
    }
}

// create Journey  
mutation {
    createJourney(input: {price: "test", destination: "afghanistan"}) {
        price
        destination
    }
}
