So, on my site, I often mess around with static site generators. For now, I'm really digging lume.land (which uses Deno). It's been smooth sailing with Vercel until recently, when suddenly, my builds started failing.
Man, I wasted so much time trying to fix it – retrying builds, messing with build commands, you name it. But, silver lining! As a total Git n00b, I stumbled upon git hooks. So, I ended up just making a pre-commit hook that generates all my HTML files before I even commit them. Now I can completely skip the build step on Vercel! (ヽ(。_°)ノ)
If you're thinking of doing something similar, here's how: Just create a file in your repo at .git/hooks/pre-commit and drop in the following content:
#!/bin/sh
set -e
/Users/ur_user/.deno/bin/deno task build
git add _site/*
exit 0
save it and chmod +x filepath to allow it to executable. I had to use full path for my obsidian git to work (not gonna spend more time debuggin that too (╯°□°)╯︵ ┻━┻)
