Migrating from Expressjs 4 to 5

This article provides a practical guide for developers preparing to migrate from Express.js 4 to version 5 (currently in alpha). It details key breaking changes, such as the deprecation of `res.send(status)` in favor of `res.status().send()`, updates to `res.json()` and `res.jsonp()`, and the shift from `res.sendfile()` to `res.sendFile()`. The author advises adapting these new patterns immediately, even while using Express 4, to ensure a smoother transition.
