What is it called when you are programming and a program automatically updates your changes when you save changes to a file?

Question

When programming there is a workflow that works like:

1. Change a file and save it.
2. The a compiler or interpreter.
3. Look at the result.

But there is also a workflow that goes like this: (actually it is similar to working with this stack overflow question Window I am typing into)

1. Start a program that watches a directory of files for changes.
2. Change a file and save it.
3. The results immediately appear as the program runs the compiler and updates the program (usually in a browser) immediately.

I'm looking for what the second workflow is generally referred to as.

Answer 1

Automatic deployment of source code changes is referred to by few different terms:

• hot reloading
• auto reloading
• live reloading
• triggered restart
• triggered execution

Personally, I hear the term hot reloading most frequently.
