Open-source has revolutionized software development, making it more accessible to programmers by providing a vast array of open-source packages at their fingertips. Repl.it aims to further this goal with its Universal Package Manager, which supports multiple languages, including JavaScript, Python, HTML/CSS/JS, and web frameworks. The package manager enables search and spec file support across all supported languages, allowing developers to easily install dependencies and manage their project's requirements. This innovation is made possible by the creation of common package manager runner abstractions, making it simple to add support for new languages by modifying a JSON config file. Repl.it also has an ambitious project in the works to build a universal package manager with the same semantics across all languages, inviting developers to join them in this endeavor.
