Node.js v18.x build error

[rhastie]

I'm currently using Node.js v16 LTS for production but testing Node.js v18. I am seeing build errors under Node.js v18.x... Any suggestions welcome?

@rhastie @garethsb did you get this working? The postcss issue suggested npm install postcss but that's not working for me with Node 19.

[peterbrightwell]

Nor with node.js v18.12.1, using corepack and yarn (and yarn add postcss)

[peterbrightwell]

In the meantime I've downgraded to node v16.18.1 (with corepack 0.14.1 and yarn 3.2.4) and yarn start runs.

(Mac users: uninstalling node that was installed using the installer is hard work, I'd recommend Homebrew :) )

Hey, @jonathan-r-thorpe, any thoughts on supporting Node v18+ ?

[rhastie]

So I've just checked the same issue is happening with Node v20.x as well. Is there anything we can do as it potentially just looks like a new syntax issue with later versions of Node

[jonathan-r-thorpe]

@garethsb in the short term pragmatically updating incompatible library versions just enough to mitigate this issue, but not so much that it requires a complete overhaul of the codebase. I'll schedule some time next week to take a look.
