Report your calories and carbs from cronometer.

Since cronometer won't release an API, I built this. This starts an express server and gives you two endpoints to display your current calorie and net carb information. The homepage / is meant to display this information on some type of screen: second monitor, iPad, etc. The page automatically refreshes at an interval.

Note:

The page displays different color lines across the screen at an interval in order to prevent screen burn in. I hope this enough. I accept no responsibility for broken screens.

The second endpoint /json is to consume the data and do as you wish. Personal, I use the JSON endpoint for displaying my calorie and carb information in my macOS menu bar.

You can run the server locally on your computer, on a computer on your network, on some server, or using a service such as glitch. In theory, if you run this on glitch, the server shouldn't sleep, but I haven't tested this.

As stated above, you need a computer to run this on.

You have to have node and npm installed. I recommend using doing so via nvm.

Obviously an account and data on cronometer.

1. Clone the repo
2. Install NPM packages

npm install

If running on ubuntu you might get some dependency errors. If so just install the dependencies for puppeteer.

sudo apt-get update && apt-get install -y libgtk2.0-0 libgtk-3-0 libnotify-dev libgconf-2-4 libnss3 libxss1 libasound2 libxtst6 xauth xvfb libgbm-dev

USERNAME="username_here" PASSWORD="your_password_here" npm run start

Or

USERNAME="username_here" PASSWORD="your_password_here" node index.js

Alternatively, you can hardcode your username and password in the index.js file.

To show more info in the terminal use the DEBUG param.

DEBUG=true USERNAME="username_here" PASSWORD="your_password_here" npm run start

To use a different port use the PORT param.

PORT=1337 USERNAME="username_here" PASSWORD="your_password_here" npm run start

To spawn the browser window and see the scrapping in action, or to do some debugging use the HEADLESS param.

HEADLESS=false USERNAME="username_here" PASSWORD="your_password_here" npm run start

If you get an error about running without --no-sandbox, use the SANDBOXMODE param.

SANDBOXMODE=false USERNAME="username_here" PASSWORD="your_password_here" npm run start

I recommend using this with the webhook option.

I use this tampermonkey script I created, which scrapes the same data in real time and sends it to the server via a webhook. All while you log your food on your computer.

Here's why:

• This updates the server faster after you log food.
• It's nicer not to hit their server and scrape the data one less time.

For a simple webhook, I use the free service patchbay.

USERNAME=username_here PASSWORD='password_here' WEBHOOKURL='https://patchbay.pub/<unique_id_here>?persist=true' npm run start
