Repl.it is expanding its support for Node.js, allowing users to easily require dependencies and have them handled by the platform. This move builds on the success of Repl.it's existing Python package support, which has enabled a wide range of exciting projects to be built. The new feature is currently in open beta, with some initial issues being addressed, including caching and global caching for packages installed across different users' Repl.it accounts. As development continues, Repl.it aims to introduce additional features such as support for package.json files and improved caching mechanisms. Users are encouraged to provide feedback on the early release to help shape its future evolution.
