Goal of example is to show how create reactive REST services on Lightbend stack with Akka and Slick.
Example contains complete REST service for entity interaction.
This application is fully tested with Unit and it tests.you don't need to launch server locally for development.my recommendation is to write a test before changes and work via TDD.to ensure that application working properly, you should run it :
All business logic is located in
core package, every package inside is related to some domain.Service classes contains high level logic that related to data manipulation, that means that service must not implement storaging and querying for the data.for storaging there are Storage classes that always have interface with two implementation, production one and in-memory one.that's needed to fasten tests of services and make it independent from each other.
To generate code coverage report, please run :
sbt clean coverage test coverageReport. then you will have HTML pages with reports in
Application packaging implemented via sbt-native-packager plugin.currently in
build.sbt enabled two types :docker and universal.
To package application as a universal app, use :
sbt universal:packageBin. Application zip archive will be generated in
To package application as docker image, use
sbt docker:publishLocal.it will generate and push application image into your local docker store.for information about publishing to external store, please, read plugin documentation.
If you want to launch application locally (its not recommended) you need to start Postgres instance locally and fulfill some env variables :
JDBC_URL- url to your database
JDBC_USER- database username
JDBC_PASSWORD- database password
After that, just run
sbt run and enjoy hacking.for better expirience you can use
sbt reStart that will give you ability to restart application without restarting of sbt.
Easiest way to deliver your application, is to do it with docker.Publish image into the store and then use docker-compose file with structure like in
Application deployed on heroku and can be accessed by URL http://akka-http-rest.herokuapp.com/.
First request can take some time, because heroku launch up project.
You can see documentation for this example on Apiary.
