Support Jest 28

See original GitHub issue

Which feature you want to improve? The migration guide includes some breaking changes, one of which is the return value of custom tranformers. They now need to return an object { code: '...' } instead of a string.

What and why you want to improve that feature Jest Preview is compatible with Jest 27. We need to support the latest version (which was just released) as well.

About the question of whether Jest < 28 works with { code } as the return value’s shape of process.

The answer is yes. I looked into Jest version 24.0.0 (just to be sure. CRA 4 uses Jest 26.6.0 actually), and it does support that interface, all the way up to version 28.
