Heimdall is the main micro-service that is responsible for user-management, ingestion of problems from endpoints, providing API endpoints for main user interface, interaction with task-runners, code submission and evaluation. Since this service basically handles all requests from the client, it's named Heimdall.

Architecture

Running the app

There are two methods to run the application. First is by building the package locally and second is using the official docker image.

# clone the repository
git clone https://github.com/YashKumarVerma/rc-heimdall
cd rc-heimdall

# install dependencies
yarn install

# start development server
yarn start:dev

Running from docker requires a hosted postgres instance (you can use a docker container for the same, just configure the network accordingly). Also note that heimdall depends on judge0 and task-runner for it's operation. While testing, use something like webhook.site to listen for outgoing requests.

# fetch the latest published image
docker pull yashkumarverma/rc-heimdall

# launch a container in production mode 
docker run -d \
    -p 80:80 \
    --name heimdall \
    -e NODE_ENV='production' \
    -e DB_HOST='some-domain.postgres.database.azure.com' \
    -e DB_USERNAME='username@xyz' \
    -e DB_PASSWORD='secure-password' \
    -e DB_NAME='postgres'\
    -e JUDGE_ENDPOINT='http://127.0.0.1:1974' \
    -e JUDGE_CALLBACK='http://52.171.196.193/judge/callback'\
    -e RUNNER_ENDPOINT_EXEC='http://127.0.0.1:8000/run' \
    -e RUNNER_ENDPOINT_SEED='http://127.0.0.1::8000/sync' \
