Development

Prerequisites

To develop it4all, you need to have installed the following programs (names of packages in Ubuntu in brackets):

1. Git (git)
2. (Open-)JDK 11 (default-jdk or openjdk-11-jdk)
3. NodeJS with NPM (nodejs, npm)
4. Docker (docker.io) (Do not forget to add yourself to group "docker" on Linux with sudo usermod -aG docker $(whoami) and log yourself out and in again)
5. Docker-compose (docker-compose)
6. sbt

sudo apt install git openjdk-11-jdk nodejs npm docker.io docker-compose

First start

# Clone the repository on the [GitLab](https://gitlab2.informatik.uni-wuerzburg.de/bje40dc/it4all.git) of the institute of computer science of the university of Wuerzburg
git clone https://gitlab2.informatik.uni-wuerzburg.de/bje40dc/it4all.git

cd it4all

# Create a folder for solutions needed by docker
mkdir -p data/web/solutions

# Set up all containers with docker-compose
docker-compose up -d

# Start the server with
sbt run

# install frontend dependencies
cd react-ui
npm i

# start frontent
npm run start

Following starts

Since the containers are all built and started, you can just restart the server with

sbt run

Common Commands for the sbt/Play Framework - Console

reload - Reload the complete Configuration of the Project (needed for changes in conf/application.conf or build.sbt)

compile - Compile all sources

clean - Delete generated files (e. g. .class)

test - Run JUnit-Tests of the Project

run - Start Application in Development mode

IntelliJ Idea IDE

Install Scala Tools Plugin for IntelliJ Idea and import the build.sbt-file

Deployment to production (Ubuntu Server)

Prerequisites

• JRE (default-jre)
• Docker with docker-compose (docker.io, docker-compose)

Running

• Create docker containers:

  docker-compose up -d

• Create solution dir or reset ownership (recursively) on data/web

• Perform first start with db init

  bin/it4all -Dplay.http.secret.key="<random string>" -Dplay.evolutions.db.default.autoApply=true

• Subsequent starts without db update:

  bin/it4all -Dplay.http.secret.key="<random string>"
