Visualization Tool

Development Environment

To start the development environment, you need a Docker runtime, e.g. Docker Desktop and Nix.

Setting up the dev environment

1. Make sure that Docker is running
2. Start the Postgres database with docker-compose up
3. Run the setup script:

yarn setup:dev

Dev server

Once the application's set up, you can start the development server with

yarn dev

👉 In Visual Studio Code, you also can run the default build task (CMD-SHIFT-B) to start the dev server, database server, and TypeScript checker (you'll need Nix for that to work).

Postgres database

If the database server is not running, run:

docker-compose up

Building the Embed script /dist/embed.js

Currently, the embed script is not automatically built when the dev server starts.

Run the following command when you're changing the source file in embed/index.ts.

yarn dev:rollup

Currently, this only bundles and initializes iframe-resizer but could be used to render charts without iframes (using custom elements or render to a generic DOM element) in the future.

Database migrations

Database migrations are run automatically when the production app starts. In development, you'll have to run them manually:

yarn db:migrate:dev

Migrations are located in db-migrations/. Write SQL or JS migrations and follow the naming convention of the existing files XXXXX-name-of-migration.{sql|js}. Migrations are immutable, you will get an error if you change an already-run migration.

For detailed instructions, please refer to the postgres-migrations documentation.

Versioning

New versions of package.json are built on GitLab CI into a separate image that will be deployed to the integration env.

yarn version

This will prompt for a new version. The postversion script will automatically try to push the created version tag to the origin repo.

Deployment

Heroku

If a Heroku app is set up (as Git remote heroku), deploy with

git push heroku master -f

Build instructions are defined in heroku.yml.

For details, see https://devcenter.heroku.com/articles/build-docker-images-heroku-yml

Abraxas

With your Abraxas credentials ...

1. Log in to https://uvek.abx-ras.ch/
2. This will prompt to open the F5 VPN client (you can download the client software once logged in). The VPN connection will be opened automatically.
3. Use Microsoft Remote Desktop to log in to the Abraxas Jump Server:
   • Remote address: 192.168.99.9
   • User: cmb\<YOUR_USER_NAME>
4. Once logged in, you should find yourself on a Windows desktop.
5. Using PuTTY (a terminal app on the desktop), connect to cmbs0404.cmb.lan via SSH. Again, use the same credentials.
6. Congrats, you are on the Abraxas dev server!

Useful commands to use:

• cd /appl/run -> go to the directory containing the docker-compose.yml
• sudo /usr/local/bin/docker-compose logs web -> display logs of the web service
• sudo /usr/local/bin/docker-compose up -d -> Rebuild services and restart after a configuration change
• sudo /usr/local/bin/docker-compose pull web -> Pull latest web image manually (should not be needed much)
• etc. (remember to use sudo for all Docker commands)

Docker (anywhere)

To pull the latest image from the GitLab registry, run:

docker login registry.ldbar.ch -u <username> -p <deploy_token>

# Pull/Run manually
docker pull registry.ldbar.ch/interactivethings/visualization-tool:master
docker run -it registry.ldbar.ch/interactivethings/visualization-tool:master

Or use docker-compose. Simplified example docker-compose.yml:

version: "3"
services:
  web:
    image: "registry.ldbar.ch/interactivethings/visualization-tool:master"
    ports:
      - "80:3000"
    restart: always
    env: DATABASE_URL=postgres://postgres@db:5432/visualization_tool
  db:
    image: "postgres:11"
    ports:
      - "5432:5432"
