This app uses the google fitness v1 rest API to store weight data.
To make your own app you will need a google cloud account and create your own credentials. See here: https://developers.google.com/fit/rest/v1/get-started
This repo will use my person oauth client ID for demonstration purposes.
git clone https://github.com/wichopy/google-fit-weight-tracker-web-client.git cd google-fit-weight-tracker-web-client npm install npm start open http://localhost:3333
Note: The app will only work on localhost at port 3333 as its the only whitelisted url
A .env file is provided to configure your own client ID.
