Check decathlon stock

Requirements

• Have opam installed and setup for easiest building
• Have a working sendmail conf for mail notifications

Building

The easiest way

Run these commands in the project root directory:

$ opam switch create . --locked # This is expected to take quite some time
$ decathlon-stock --help

The other ways

Install within an already existing opam switch:

$ opam pin add .
$ decathlon-stock --help

Build and run without installing, if dependencies are met:

$ dune exec decathlon-stock -- --help

Running

Get the URL of a decathlon product that you want to watch the stock for (for instance, https://www.decathlon.fr/p/some-product-name/_/R-p-12345).

Then, to check every fifteen minutes the stock of this item for the sizes S and XL, run:

$ decathlon-stock \
    --mail your@mail.org \
    --period 15 \
    --sizes S,XL
    "https://www.decathlon.fr/p/some-product-name/_/R-p-12345"

The program will then run without stopping, printing the stock every 15 minutes. Upon finding some new stock for at least one of the specified sizes, it will send a mail to the provided address. Only one mail will be send for each size when stock becomes available. If it then becomes out of stock, then available again, another mail will be sent.
