Starting a new card from boilerplate-card with devcontainer

Note: this is available only in vscode ensure you have the Remote Containers extension installed.

  1. Fork and clone the repository.
  2. Open a devcontainer terminal and run npm start when it's ready.
  3. The compiled .js file will be accessible on http://127.0.0.1:5000/boilerplate-card.js.
  4. On a running Home Assistant installation add this to your Lovelace resources:
- url: 'http://127.0.0.1:5000/boilerplate-card.js'
  type: module

Change "127.0.0.1" to the IP of your development machine.

Bonus

If you need a fresh test instance you can install a fresh Home Assistant instance inside the devcontainer as well.

  1. Run the command container start.
  2. Home Assistant will install and will eventually be running on port 9123
