feat: saleor seeder script

[jmalinkiewicz]

This pull requests introduces a new seeder package. It solves the issue I've personally experienced myself - the tedious task of setting up Saleor Sandbox (creating attributes, page types, assigning attributes and filling them etc.).

Running the script:

pnpm seed

Wipes all the default Saleor Sandbox types and creates all data models specified in the docs and populates them with mock data.

Before running the script:

The script running:

Screen.Recording.2026-02-13.at.20.01.06.mp4

After the script was run:

The SALEOR_APP_TOKEN environment variable must have the following permissions granted:

MANAGE_PRODUCTS
MANAGE_PRODUCT_TYPES_AND_ATTRIBUTES
MANAGE_PAGES
MANAGE_PAGE_TYPES_AND_ATTRIBUTES
MANAGE_MENUS

First of all, thank you for your work on this — it’s really appreciated. I’ll get back to you shortly.

I need to discuss this apprach with the team, as we’ve been planning something similar to simplify and improve the setup/installation flow with Saleor.

There is definitely room for improvement here. The script is now only useful for devs who want to set up their environment quickly.

I think this script could use a flag/question step where you can define whether you want to only create the data models, or also populate with mock data.

This way the script would be useful for people setting up their store for the "real world" use case.

I just learned about the Saleor Configurator. The logic in this PR overlaps with the functionality already handled there.

I will refactor this PR to use the Saleor Configurator, and also remove the mock data functionality, since a Saleor Environment is already populated with mock data by default.
