Checks Apple Store inventory for new MacBook Pro models.

Run npm install to load the project's dependencies. Assumes recent node version (tested with v17.0.1, but should work with earlier versions).

• request for simplifying network requests
• node-notifier for sending local notifications when stock is detected

First, find the store number of your local Apple Store using the included table (see here for Canadian stores). Then run the script, passing the number as an argument:

$ node index.js R123

This will query Apple's retail inventory for all 2021 MacBook Pro variants that are known to be stocked in-store. R123 is a store in Nashvile, TN, so that store plus others in the surrouding area will be queried. The results are logged to stdout, and if any models are found, a notification will be sent.

You might want this script to run every minute or so, to make sure you don't miss your desired model coming into stock. To run the script repeatedly, update the following line to match your local environment and add it to crontab. You will need to update the entry to point to the script directory on your local, your node location (use which node), and the desired log output file.

*/1 * * * * cd ~/path/to/script/folder/ && /usr/local/bin/node index.js R123 > ~/path/to/desired/log/script_output.log 2>&1

This script checks for most known MacBook Pro variants that are currently stocked by Apple Stores, and has some special logic for my personal favorite model (14" M1 Max 32 Core GPU, 64GB RAM, 2TB SSD in both Silver and Space Gray). You may want to tweak the code if you're not interested in the "Ultimate" models.

For reference, here's how Apple's fulfillment API works.
