CRA 4.0 support?

[xinghul]

Hi there, not entirely sure what's happening, I tried to upgrade to CRA 4.0, but I got this error:

node_modules/react-scripts/scripts/utils/verifyTypeScriptSetup.js:241
      appTsConfig.compilerOptions[option] = value;
                                          ^

TypeError: Cannot add property paths, object is not extensible

nvm, this is irrelevant.

Hi, @xinghul, why did you closed as irrelevant? Write your thoughts or problem more detailed to let people know what they can experienced and how to solve. It save time for many people.

Hi, @nvt1995-dev also provide your experience here.

Also relevant issue: create-react-app #9429 - I will see if will have time.

Also use create-react-app 4.0 will impossible without this pull create-react-app #9921 - int is merged but not released - so wait when any create-react-app version above 4.0 will be released (or get patch manually using patch-package).

It is actual - so I reopen issue

@oklas I digged into the code and realized it's an issue with CRA 4.0.

The pull create-react-app #9921 is merged but not released yet. Currently that is the only thing is blocking to work.

Here the commit 600ffb4 (on example project) to demonstrate how to apply manually patch for 9921 using patch-package.

Form outside of root TS does not see libraries, but JS works. In the root (near src) TS works.

Docs also actualised to simplify usage.

Currently problem does not concern react-app-rewire-alias and it will be worked with next release of create-react-app (or with previous) or with mentioned above patch. So I close this for now. Anyone feel free to write or reopen if any. Subscribe news at twitter.
