How to pull in new changes in a CRA custom template to a live ReactJS application?

[satyajitrpatnaik]

I recently created a custom template based out of create-react-app, following the article at - https://create-react-app.dev/docs/custom-templates/.

After creating the CRA template, I hosted it on a private NPM registry.

I reused the template to create multiple ReactJS applications thereon. During this time, there were updates made to the CRA custom template as well.

I am not sure how I can pull these new template updates to the ReactJS projects that were created out it.

Is there a way out of the box to pull in updates from a CRA custom template to a ReactJS application?

@satyajitrpatnaik that isn't a feature of create react app.
Nor is it something that can be easily done with template in general, it would either overwrite your changes or cause merge conflicts.

It sounds like you are looking for migration codemods?
React has some codemods here: https://github.com/reactjs/react-codemod, you could write your own custom codemods if you want.

codemods sounds like a big help to my case. I will definitely use the library that you have mentioned in my applications. Thank you for the lead.
