@earthlingdavey Love it thanks! I used this back in the day for Headless multisite setup on OG faust with gqty.
Nice, well thanks for sharing a solid foundation and an inspiration.
Do you still run headless WP? And/or Multi Site?
... I'm looking for a nice way to use a Typescript FE with WP headless.
@earthlingdavey Yup! Running it on my personal website with a bunch of custom hacks

The monorepo might be overkill but you can probably clone the apps/web and be fine
Oh nice, looks good!
Ideally I would like to avoid Next.js - lot's of good WP stuff in the repo too, thanks for making the source available!

Hi Cesar, nice work :) I made a version for ACF 6 here https://gist.github.com/EarthlingDavey/8361f504f4df7303ff8dc41f1b7400e3
