Questions tagged [hot-reload]

Use this tag for questions about the hot-reload functionality of programming tools.

Hot-reload is the ability to view the effects of programming changes as soon as they are made without having to manually perform additional actions such as compiling, deploying, reloading, or restarting. These steps may still happen, but they are automatically performed by an agent that watches for changes to the source code.

Using hot-reload decreases the time for a development cycle and prevents developers from wasting time when they forget to perform steps after making changes then can't figure out why their changes didn't work.
