What exactly does the 'app://' scheme entail when it comes to assets within Webpack-5-generated applications during development mode?

I've recently noticed a unique behavior in my Webpack 5-built application during development mode. The browser requests assets using a URL with an interesting app:// scheme. An example of this is:

app:///node_modules/dir/to/package/index.js

In the Debugger tab of the devtools, under Sources, I observed the actual tree structure under app://:

https://i.sstatic.net/zfk9r.png

The presence of the app:// tree only seems to appear under Sources when the app is built in development mode (using Webpack 5), indicating a potential link to Webpack. However, there is no mention of this behavior in the Webpack documentation.

Curiously, searching online yields almost no information about app://, adding to the mystery surrounding it. This leads me to believe that it may be specific to Webpack and simply poorly documented or not documented at all.

If anyone has insights on this matter, I would greatly appreciate any input!

Thank you!

Answer №1

In simple terms, the prefix app:// denotes the location where your code is hosted for you to access. It is possible to change this hosting location by adjusting the webpack configuration file. Check out the webpack-dev-server documentation for more information.

As an illustration, here's a snapshot from a project I am currently developing where the static server instance is launched at localhost:3000, granting me access to the compiled project files.
