modxRepository was created in 2012 to deploy a custom MODX Revolution transport package repository.

MODX already had a package manager and transport packages, but individual developers or studios depended on external distribution infrastructure. modxRepository allowed setting up a custom package source and installing custom add-ons from it using standard MODX tools.

This is especially important in the context of the overall component ecosystem. When custom phpTemplates, modxSmarty, modxSite, and other base packages appear, a mechanism is needed through which they can be installed and updated as normal project dependencies.

Thus, modxRepository transformed a set of source files into a distributable ecosystem. Components could be built, versioned, published, and connected via the standard MODX package manager without manually copying code between projects.

modxRepository is part of the general Fi1osof component ecosystem. The history of creating the custom repository is described in a 2012 publication on Habr: https://habr.com/ru/articles/163077/
