Showcase how to create a Todo list where the different tasks are created, read, updated, or deleted from the database.

TODO Application with Quarkus

This is an example application based on a Todo list where the different tasks are created, read, updated, or deleted from the database. Default this application for convenience purposes uses an in-memory database called H2 that allows you to run this application without depending on an external database being available. However, the H2 database is not supported to run in native mode, so before you do the native compilation, you will have to switch to the postgresql branch.

Branches:

• master - use H2 (in memory), no native support
• postgresql - use posgresql, support native mode

Compile and run on a JVM

mvn package
java -jar target/todo-backend-1.0-SNAPSHOT-runner.jar

Then, open: http://localhost:8080/

Development mode

mvn quarkus:dev

Then, open: http://localhost:8080/

Compile to Native and run with PostgresSQL ( in a container )

Compile:

git checkout --track origin/postgresql
mvn clean package -Pnative

Run:

docker run --ulimit memlock=-1:-1 -it --rm=true --memory-swappiness=0 \
    --name postgres-quarkus-rest-http-crud \
    -e POSTGRES_USER=restcrud \
    -e POSTGRES_PASSWORD=restcrud \
    -e POSTGRES_DB=rest-crud \
    -p 5432:5432 postgres:10.5
