Firebase functions imagemagick version support webp?

[David DeRemer]

We have some Firebase Functions that process images into various sizes. We were considering using .webp format... but when we try using ImageMagick `convert` in a function, it throws a child process error. Perhaps webp isn't available on the machines running Firebase Functions?

Seems like Google infrastructure should support a Google format, right? :-)

Hi David,

Doesn't look like it's supported. Note that you can upload a binary as part of your deploy, so you could provide your own IM version or go with the sharp lib, which bypasses the need to deal with temp files and such.

Thanks Kato! Ace help as usual.

For future viewers, here's a SO link that explains uploading a binary: https://stackoverflow.com/a/42777596/3457022

Cheers, thanks for sharing links for others ♡

P.S. Looks like I forgot to point out that this is great feedback. I've submitted a feature request to add .webp into the default binary. It may not get any traction but we've asked for improvement based on your input.

Great!

One more question… on that SO, Doug Stevenson says "Bear in mind that you have a limited about of temp disk space and memory to work with. In fact, temp disk is stored in memory, so if you have a large video, you could easily run out of memory."

I assume he’s just talking about the file being manipulated, but it got me wondering… Does uploading a binary have any effect on the function’s temp disk space and memory? Anything to worry about there?

I don't think that affects temp space or memory directly. I think the quota to keep in mind here is total deploy size as you could run into that with too many binaries (but you'd have to work pretty hard).
