Repository containing thin-edge.io flows to illustrate flows in a more production-like environment which covers;

• Repository structure that defines multiple
• Writing flows in TypeScript
• Using 3rd party dependencies within flows
• Transpile TypeScript to ES2018
• Writing unit test and run them, using Jest
• Packaging individual flows

The repository also uses Github workflows to run Pull Request checks, and also using an automated release process using release-please.

Feel-free to copy this repository and modify it to your liking, or you can also contribute new examples by raising a Pull Request.

You can build the flows locally with the following steps which requires nodejs >= 20.

1. Install the dependencies (using npm ci instead of npm install to install the exact versions defined in the package-lock.json file)

   npm ci

2. Build all the flows

   npm run build-all

3. Publish the flows (locally) so that they can be either uploaded to Cumulocity or manually installed

   npm run publish

   The files are located under the dist/ directory

   $ ls -c1 dist/
