The build began failing once I added the corresponding customManager to help keep the tsconfig.json file in-sync with the replacement updates.

Won't this start a cascading series of replacements? e.g. 10 -> 12 -> 14 -> 16 -> 18 etc.

It would, but I figured users could decide if they applied the replacement, declined it, or left it open.

It would be nice if it could be kept in sync with the repositories node version - or: have these replacements dependant on another dependency version

Hi there,

This PR appears to have been inactive for a while. Please let us know if you are still working on it, or if we can close it for now.

Thanks, the Renovate team

I would still like to find a solution to help automate the @tsconfig/bases updates.

Open to other suggestions on ways to implement this. Are there other packages that follow a similar need?

[setchy]

Why would we need the replacements? Won't the custom manager alone be enough

It's been a while since I looked into this, but to my knowledge the replacements were needed as the depName itself changes

@viceice - does this now make sense, splitting the logic between a set of replacements, and then a customManager for keeping the tsconfig extends updated
