Motivation / Use-Case

Some applications use public paths (to avoid strong differences between dev and prod builds). I set it via output.publicPath, and it seems a bit inconvenient to me that the urls in the terminal are obtained without taking publicPath into account. These can be simple applications without routing, and you have to go to / and then manually add publicPath. I suggest outputting the url with publicPath if it is set statically, if it is determined on the fly - output without it.

Now, with config like this:

output: {
  publicPath: "/my-public-path/",
}

We getting this:

<i> [webpack-dev-server] Project is running at:
<i> [webpack-dev-server] Loopback: http://localhost:8080/, http://[::1]:8080/
<i> [webpack-dev-server] On Your Network (IPv4): http://10.252.1.16:8080/
<i> [webpack-dev-server] Content not from webpack is served from '/home/user/Project/src' directory
<i> [webpack-dev-server] 404s will fallback to '/index.html'

My proposal is:

<i> [webpack-dev-server] Project is running at:
<i> [webpack-dev-server] Loopback: http://localhost:8080/my-public-path/, http://[::1]:8080/my-public-path/
<i> [webpack-dev-server] On Your Network (IPv4): http://10.252.1.16:8080/my-public-path/
<i> [webpack-dev-server] Content not from webpack is served from '/home/user/Project/src' directory

We need respect function too... But yeah, we known about it only after compilation, so maybe we can improve our message and write - something like you can have custom public path, please navigate in your browsers to the point that you required (just an example, feel free to improve it)

[adubrouski]

@alexander-akait I think adding an info message if public path is auto or function would be a good idea, can you check this commit?

[alexander-akait]

We should output this only for function, auto is like /, so it is unnecessary

[adubrouski]

@alexander-akait

Hmm, webpack documentation says that the "auto" value allows you to automatically infer the public path value based on the values ​​in the scripts. Are you sure that we should keep default behavior for "auto" value?

[alexander-akait]

Yes, you are right, but mostly it used only for /, so I think it can be a little bit spammy

[adubrouski]

Ok, I fixed it in this commit. Can you check?

[alexander-akait]

Looks good, I will look deeply before the next release, thank you
