Not only is it important that you write your component to be cross-platform, you must also test your component on all platforms.

If you are trying to test a library after you've published it, check out managing public libraries.


Once you've created an Adalo component with npx create-adalo-component, you can immediately test your component on web. To do so, run in your shell:

# login with your adalo credentials
npx adalo login
# start the development server
npx adalo dev

Now, when you add a component on Adalo, you will see a new tab called "development" with your component. Changes to the code will hot reload the page besides changes to any manifest.json. If you make any changes to manifest.json, you must restart your component.
