Document how to upgrade react-scripts after creating an app

[keyz]

Also, can we add a version checking that prompts users to upgrade their react-scripts dependency when there's a new version? :)

[dolchi21]

would editing the package.json dep and installing do it? (always checking for compatibility errors)

[keyz]

Yeah, I think editing package.json or npm update will do it but it hasn't been documented. Just posting here to see if we want something more than that.

Imagine if every npm module you installed, also prompted you to upgrade it when there's a new version. That would be pretty annoying. ;-) For a lot of people, there's actually no reason to upgrade react-scripts - if you're on an older, more-stable version, and you're happy with it, then just keep being happy with it. We also might release a breaking change in react-scripts at some point and then an automated message that encourages people to update would be counterproductive.

Totally agree with @lacker.

We've had this discussion quite a few times over at react-boilerplate – whatever version you use will work perfectly fine, there's no need to upgrade!

[gaearon]

We actually should document that so reopening.
But I agree we shouldn’t ask people to update.

This is also a little different to react-boilerplate. Updating a boilerplate doesn't really make sense/is a nightmare to do. On the other hand we plan for most updates to react-scripts to be backwards compatible, but there could be performance enhancements and new features. For this reason I think we should suggest that people may want to upgrade.

I probably don't think we should prompt people to upgrade though, just suggest that they do in the documentation.

If they're not running npm out --depth=0 on a regular basis, they don't deserve your sweet new features 😸

i need a feature that is on 1.0.0 and my react-scripts are in 0.9.5 how do I update them?

[gaearon]

You can find the instructions in release notes, as always.

@gaearon if I am on 1.0.14 and I want to upgrade to 1.0.17, must I yarn add --exact each version individually or can I go directly to yarn add --exact react-scripts@1.0.17?

[ghost]

It might seem like a silly question and it is. I was imagining that some sort of local data or config had to change. However (duh) there is no build configuration here or anything else to migrate. So I think the answer is probably: No. I do not need to install each version individually. Sorry for asking silly questions!

I'm seeing this warning on a project I created using create-react-app:

Official documentation on how to upgrade would be really useful.

Documentation on how to upgrade is on every release.
