Hi all.

I am trying out Homey app development, and I am trying to use some of the principles and practices I am used to from web applications. So I installed eslint, typescript and other tools to be able to write in similar fashions to how I am used to. However, doing this made the homey-app go from 2 MB to 14 MB (so far), and now it takes over 30 seconds just to start it up.

Also, I feel it is a little impractical to close and restart the app every time I need to test a code change.

Is there a more practical way? A watch mode (similar to when developing web applications with webpack) or something else making the development environment a bit more practical.

Make sure those are listed in `devDependencies` in `package.json`. When they are, they should be removed from the file that gets uploaded to Homey.

This has been on the wish list for developers [for more than 4 years now](https://github.com/athombv/node-athom-cli/issues/7), but Athom never bothered. But hey, at least the developer website got a cool permanent dark theme…

Ah, I had it all in `devDependencies`, except the `eslint` package, now it got back down to 2MB. Thanks 😃
