These are modules used by apps - you can use them from a Bangle.js app with:

var testmodule = require("testmodule");
testmodule.test()

When apps that use these modules are uploaded via the app loader, the module is automatically included in the app's source. However when developing via the IDE the module won't get pulled in by default.

To fix this you have three options:

This is reasonably easy to set up, but it's more difficult to make changes and upload:

• Follow the steps here to set up your own App Loader: https://www.espruino.com/Bangle.js+App+Loader
• Make changes to that repository
• Refresh and upload your app from the app loader (you can have the IDE connected at the same time so you can see any error messages)

This allows you to develop both the app and module very quickly, but the app is uploaded in a slightly different way to what you'd get when you use the App Loader or the method below:

• Load the module's source file in the Web IDE
• Click the down-arrow below the upload button, then Storage
• Click New File, type your_module_name as the name (with no .js extension), click Ok
• Now Click the Upload icon.

You can now upload the app direct from the IDE. You can even leave a second Web IDE window open (one for the app, one for the module) to allow you to change the module.

This is nice and easy (and the results are the same as if the app was uploaded via the app loader), however you cannot then make/test changes to the module.

• In the IDE, Click the Settings icon in the top right
• Click Communications and scroll down to Module URL
• Now change the module URL from the default of https://www.espruino.com/modules to https://banglejs.com/apps/modules|https://www.espruino.com/modules

The next time you upload your app, the module will automatically be included.
