Support React 17

React v17 has been released and is stable with no major breaking changes from v16.

Problem

Our project is currently stuck at React v16 because this package's peer dependency to react is locked to ^16.4.2. Blocking us from upgrading out of v16.

Expected behavior

I'm suggesting we add v17 to the peer dependencies: react: >=16.4.2 || ~17.0.
So that we are able to move our projects to React 17

+1 too lazy to pass to final form yet, and i rather stop doing npm i --force all the time :p

[rkhunt007]

What is the solution for now? npm i --force?

[erwanriou]

I do that in docker to fix the issue.
You can also manually format your package-lock, but carefully.

Installing package is one thing, it's possible with a yarn or using flags --force / --legacy-peer-deps with a npm. Bigger problem is that package is not fixed to accept fixes that made for React 16.8 - 17. It's time to drop deprecated lifecycle methods.

Editing package requirement doesn't fix the problem.

at the end i made the migration to react-final-form that is way much better. Its a little work but it's quite compatible and the whole everything seems faster.
