Getting started

You are almost done, only a few steps left:

1. Create a new repository on GitHub with the name ioBroker.cab

2. Initialize the current folder as a new git repository:

   git init
   git add .
   git commit -m "Initial commit"

3. Link your local repository with the one on GitHub:

   git remote add origin https://github.com/BrummF/ioBroker.cab

4. Push all files to the GitHub repo:

   git push origin master

5. Head over to src/main.ts and start programming!

Best Practices

We've collected some best practices regarding ioBroker development and coding in general. If you're new to ioBroker or Node.js, you should check them out. If you're already experienced, you should also take a look at them - you might learn something new :)

Scripts in package.json

Several npm scripts are predefined for your convenience. You can run them using npm run <scriptname>

Script name	Description
build	Re-compile the TypeScript sources.
watch	Re-compile the TypeScript sources and watch for changes.
test:ts	Executes the tests you defined in *.test.ts files.
test:package	Ensures your package.json and io-package.json are valid.
test:unit	Tests the adapter startup with unit tests (fast, but might require module mocks to work).
test:integration	Tests the adapter startup with an actual instance of ioBroker.
test	Performs a minimal test run on package files and your tests.
lint	Runs ESLint to check your code for formatting errors and potential bugs.

Writing tests

When done right, testing code is invaluable, because it gives you the confidence to change your code while knowing exactly if and when something breaks. A good read on the topic of test-driven development is https://hackernoon.com/introduction-to-test-driven-development-tdd-61a13bc92d92. Although writing tests before the code might seem strange at first, but it has very clear upsides.

The template provides you with basic tests for the adapter startup and package files. It is recommended that you add your own tests into the mix.

Publishing the adapter

Since you have chosen GitHub Actions as your CI service, you can enable automatic releases on npm whenever you push a new git tag that matches the form v<major>.<minor>.<patch>. The necessary steps are described in .github/workflows/test-and-release.yml.

To get your adapter released in ioBroker, please refer to the documentation of ioBroker.repositories.

Test the adapter manually on a local ioBroker installation

In order to install the adapter locally without publishing, the following steps are recommended:

1. Create a tarball from your dev directory:

   npm pack

2. Upload the resulting file to your ioBroker host
3. Install it locally (The paths are different on Windows):

   cd /opt/iobroker
   npm i /path/to/tarball.tgz

For later updates, the above procedure is not necessary. Just do the following:

1. Overwrite the changed files in the adapter directory (/opt/iobroker/node_modules/iobroker.cab)
2. Execute iobroker upload cab on the ioBroker host
