Get colored console output in Netlify logs with this One Weird Trick!

Support
,
#1

Sometimes you may see colored output in your local development which loses its color when you run it in Netlify deploy logs. Today (2 years in using Netlify) I learned that it’s not Netlify’s fault! Some popular output coloring libraries like chalk detect if they are in a CI environment and turn off colors!

To force it on, you can set a FORCE_COLOR environment variable = true as per the underlying supports-color library.

Looks like it’s not compatible with Gatsby — my builds fails for no reason when I add FORCE_COLOR=true, and it stops failing when I remove it.

If you’d like to link us to your build, that’s probably some misapplication of the value, rather than the value itself breaking your build.

hi @antoinerousseau - thanks for your patience. We started looking into this issue - but its beyond our bandwidth to be looking into this just now, i’m afraid. If you’d like to keep digging and come up with a solution, please post it here! and if we find some time somewhere to take another look, we will do the same. thanks for pointing this out. :muscle:
