Fitbit SDK Types

Add types to your Fitbit project to use safely the SDK, work safely with TypeScript preventing you of doing stupid mistakes.

How to use in your app project

1. Execute npm install --save-dev fitbit-sdk-types to add this type definitions.
2. include them in your project's tsconfig.json file. It sould look like this tsconfig.json:

{
	"extends": "./node_modules/@fitbit/sdk/sdk-tsconfig.json",
	"include": ["node_modules/fitbit-sdk-types/src", "./**/*.ts", "./**/*.tsx"]
}

1. Rename your files from .js to .ts and use it. For example, app/index.ts:

import { Accelerometer } from 'accelerometer';

const acc = new Accelerometer();
console.log(acc.activated);
console.log(acc.potato); // error

Examples

You can see a ton of official examples working as tests right here, under the ./test path.

Gotchas

• Avoid using any in callbacks of defined functions: TypeScript will give it the correct type, but only if you let it be. If you cast them as any other type, you could be hiding errors (either in your code or in this type definition, or even in the official documentation).

• Be careful about what you import: Currently, there is only one Fitbit build process for up to 3 different targets -to know: app, companion and settings-. So because of this, I didn't found a way of having one single tsconfig.json called from the fitbit-cli and different typings per target. So you will have to declare them all together, knowing that -for example- although there is an ambien module for accelerometer, it won't exist inside the companion target.

Make a PR submitting at least the desired test examples to work under the .test path, ideally with some link to any of the Fitbit official sources to get more info.
