Step By Step

1. Installation

Make sure you have npm, and node installed on your system

git init
git clone git@github.com:buds-lab/cozie.git
cd cozie
npm install
npx fitbit

Once successful you can open the Fitbit OS Simulator, run build, and then install to launch the project

3. Uploading to the app store

Generally, you should just make a pull request and PJ will update the app on the store. However if you would like to create a completely new clone then this tutorial explains how

8 Sending Data to the Cloud

This is done through an Amazon API Gateway. See https://github.com/buds-lab/cozie-gateway for the source AWS API Code.

let url = `https://ay1bwnlt74.execute-api.us-east-1.amazonaws.com/test`
fetch(url, {
        method: 'POST',
        headers: {
          'Accept': 'application/json',
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(data) // data here is the cozie feedback data object
      })
      .then(res => {
          console.log(JSON.stringify(res))
      })
      .catch(function(error) {
          console.log('There has been a problem with your fetch operation: ', error.message);
      });
