Cherrypick warning and removal of react create class #9771

flarnie · 2017-05-25T02:24:56Z

Edit: Fixed the rest of the issues, this should be good to go now.

Changes:
cherrypick and hand-edit various parts of commits from master to do the following -

add create-react-class and prop-types as dependencies of React
add the deprecation warning for React.createClass and get it from the create-react-class package
add tests for the React.createClass and React.PropTypes deprecation warnings
adds test for create-react-class as used in React

(Original PR message below)

This is a butchered version of #9232 with some of #9399 mixed in. I don't have the tests passing, and there is something not quite right about the way this landed.

Not sure if we want createReactClass or ReactClass.createClass, and updating that caused an error:

src/isomorphic/classic/class/createClass.js was added to master in https://github.com/facebook/react/pull/9399/files
that file is used in src/isomorphic/React.js and itself uses var {Component} = require('ReactBaseClasses');
in 15.6, that line throws Cannot find module 'ReactBaseClasses' from 'createClass.js' and I have no idea why
So instead I left it using the old implementation of 'createClass'

There is still a test failing for ReactART and I have not figure out why. Something in ReactReconcileTransaction.perform triggers TypeError: Cannot read property 'call' of undefined.

I'd be happy for any guidance or tips from folks who made those PRs - @acdlite and/or @bvaughn. I am going to delay doing a RC of 15.6 because this is pretty vital to get right.

Still TODO: improve the deprecation message itself.

I moved ReactComponent.js and ReactPureComponent.js into one file on master (#8918) to work around a www issue but didn’t do this for 15. So this is why the file is not found.

Thank you @gaearon - I was also tired by the time I got that far. Going to fix this up now, and your hint about that file will help.

yarn.lock

    create-hash "^1.1.0"
    inherits "^2.0.1"
+    ripemd160 "^2.0.0"
+    safe-buffer "^5.0.1"
+    sha.js "^2.4.8"



Didn't mean to update all these versions. Will probably make a separate PR with an update to yarn.lock.

**what is the change?:** A couple of bugs and holes were introduced when cherry-picking facebook#9232 onto the 15.6 branch. This fixes them. We also needed to add some logic from facebook#9399 **why make this change?:** To keep tests passing and get this change working. **test plan:** `yarn test` **issue:** facebook#9398

**what is the change?:** - Remove some outdated 'require' statements that got orphaned in 'React.js' - Change 'warning' to 'lowPriorityWarning' for 'React.createClass' - Fix syntax issues in 'React-test' - Use 'creatReactClass' instead of ES6 class in ReactART - Update 'prop-type' dependency to use no higher than 15.7 because 15.8 limits the number of warnings, and this causes a test to fail. - Fix some mixed-up and misnamed variables in `React.js` - Rebase onto commit that updates deprecation messages - Update a test based on new deprecation messages **why make this change?:** These were bugs introduced by rebasing and tests caught the regressions. **test plan:** `yarn test` **issue:** facebook#9398

flarnie · 2017-05-25T20:54:54Z

Weird - yarn prettier changes nothing locally, and when I try to push git says "Everything up-to-date". So not sure why prettier is failing. I'd like to get CI passing again though.

**what is the change?:** I didn't mean to commit changes to `yarn.lock` except for the `prop-types` and `create-react-class` updates. **why make this change?:** To minimize the changes we make to dependency versions. **test plan:** `rm -rf node_modules` `yarn install` `yarn run build` `yarn test`

Why did create-react-class and prop-types move from devDependencies to dependencies?

flarnie · 2017-05-25T21:55:26Z

In #9399 we swap out our own React.createClass for the create-react-class package under the hood, and do the same for React.PropTypes, delegating to prop-types.
It looks like we did the prop-types delegation before 15.6? So not sure if it's a problem in earlier versions that prop-types is a devDependency.
It should get turned into a no-op in production though, right?
Might be worth looking more at how this affects different builds.

But in general - React is actually using those packages until we remove those APIs. Also I added a call to createReactClass to ReactART to fix a cryptic error. Maybe we don't need prop-types but I was copying from #9399

flarnie · 2017-05-25T22:12:10Z

Just looked and I think it seems safer to keep prop-types as a dependency in this version. We could do some extra stuff to make it dev only in this version, but since we will be removing it from React in 16.0 I don't think it's worth any extra effort at this point.

sophiebits · 2017-05-25T22:14:42Z

👍 I don't think it makes a difference. As far as I know we don't ever do a non-dev install of the root package.json's dependencies.

Where is the source code of create-react-class? https://www.npmjs.com/package/create-react-class claims that the source code is in this repo, but this repo seems to be depending on the create-react-class package.

gaearon · 2017-05-26T11:37:15Z

It is in the 15.6-dev branch.

Wilfred · 2017-05-26T12:15:18Z

Thanks. For future reference, it's here: https://github.com/facebook/react/tree/15.6-dev/addons/create-react-class
