Repro steps.

Include Font-Awesome in the project. Run ng build. The dist folder contains the Font-Awesome font files with missing extensions:

+1 getting same issue. Seems to be happening for .woff2 and .ttf file extensions too. I also had a straggler image (outside of assets folder) and that was missing its extension (.png) too.

Same Problem here. I just tripped over it, because the IIS will not serve files without an known extension, under nginx no problem. This problem seems to affect fonts (woff and woff2) as well as images (png).

I confirm that the 1.4.8 version breaks loading font-awesome. I just downgrade to 1.4.7 which works fine.

[martino01]

Same here. The issue seems to be in the 1.4.8 version. Downgrading resolves the problem.

I can only guess this is caused by 776af86

@filipesilva you might want to check this out.

This is indeed caused by 776af86#diff-9eb0a75e499bdadd44d6dc62218812b8R193, the .[ext] bit is missing there.

[karloscode]

Same problem too.

[Bidthedog]

Having the same problem. ng serve works as expected, but once built and uploaded to an IIS server, the files without extensions can't be served.

We should have this resolved soon, when #8108 is merged and released.
