Upgrade to modern version of Rollup and related plugins

[0xdevalias]

The inspiration for this came from @jasonwilliams 's PR for attempting to add sourcemap output support to React's builds:

• Distribute source maps for easier debugging in Chrome's Performance tab #20186
  • Add source maps #21946

But I figured that it would be useful to minimise the scope of changes in that PR, and to modernise the build tooling along the way.

---

There have been quite a few version releases for Rollup and the plugins that are currently used, as well as a number of the official Rollup plugins changing package name to use the @rollup/* package prefix.

Looking at package.json we can see all of the current Rollup packages:

// ..snip..
    "rollup": "^1.19.4",
    "rollup-plugin-babel": "^4.0.1",
    "rollup-plugin-commonjs": "^9.3.4",
    "rollup-plugin-node-resolve": "^2.1.1",
    "rollup-plugin-prettier": "^0.6.0",
    "rollup-plugin-replace": "^2.2.0",
    "rollup-plugin-strip-banner": "^0.2.0",
// ..snip..

And using grep, we can see some additional usages under packages/:

⇒  grep -r 'rollup' package.json packages/*/package.json
package.json:    "rollup": "^1.19.4",
package.json:    "rollup-plugin-babel": "^4.0.1",
package.json:    "rollup-plugin-commonjs": "^9.3.4",
package.json:    "rollup-plugin-node-resolve": "^2.1.1",
package.json:    "rollup-plugin-prettier": "^0.6.0",
package.json:    "rollup-plugin-replace": "^2.2.0",
package.json:    "rollup-plugin-strip-banner": "^0.2.0",
package.json:    "build": "node ./scripts/rollup/build.js",
package.json:    "build-combined": "node ./scripts/rollup/build-all-release-channels.js",
package.json:    "lint-build": "node ./scripts/rollup/validate/index.js",

packages/react-devtools-extensions/package.json:    "rollup-plugin-commonjs": "^9.3.4",
packages/react-devtools-extensions/package.json:    "rollup-plugin-node-resolve": "^2.1.1",

The following is an attempt to capture all of the relevant information about package name changes, new versions, breaking changes, etc for these packages:

• https://github.com/rollup/rollup

    • Lockfile currently resolves to version "1.31.1"
      • https://github.com/rollup/rollup/blob/master/CHANGELOG.md#1311

            • .custom factory is now available as separate createBabelInputPluginFactory export

            • Removed externalHelpers & runtimeHelpers options. There is now a single babelHelpers option which can take one of 'bundled', 'inline', 'runtime' and 'external' as a value. The default is 'bundled' which matches 4.x behavior, but it is recommended to configure this option explicitly.

    • Edit: Seems there is a secondary changelog in the README that mentions a breaking change: https://github.com/mjeanroy/rollup-plugin-prettier#changelogs

      • Breaking Change: prettier dependency is now a peer dependency instead of a "direct" dependency: user of the plugin can choose to use prettier 1.x.x or prettier 2.x.x (note that this plugin should be compatible with all versions of prettier).

If any of these updates rely on a node version later than 10.x, then the following PR may have to land first, otherwise things might break on AppVeyor:

• Is AppVeyor still used to test against Windows, can it be moved to CircleCI, and/or can we update it to use a modern/supported version of Node? #24891
  • bump AppVeyor Node version from '10.x' to '14.x' (current Maintenance LTS version) #24892

---

My plan/intent is to work through all of this and create a PR updating Rollup and the related plugins; but I wanted to create this issue in the meantime to capture what I have done so far, and also check whether there would be any issues/concerns with a PR like this being made.

Edit: PR opened in:

• Update Rollup and related plugins to their most recent versions #24916

[0xdevalias]

It seems yarn 1.x's remove doesn't update the yarn.lock file particularly well.. is there a best practice way for doing this, or is it just a manual sort of thing to clean up?

• Running yarn install after removing a dep manually doesn't remove it from the yarn.lock yarnpkg/yarn#2581

eg. yarn remove --force --ignore-workspace-root-check rollup-plugin-babel only updated package.json, not yarn.lock

---

Edit: I wonder if this is because it's used in other packages as well?

Edit 2: I tried using yarn's workspace command to manipulate the other packages:

• https://classic.yarnpkg.com/en/docs/cli/workspace
• https://classic.yarnpkg.com/lang/en/docs/cli/add/

But then I ran into an error about "Failed to install dependencies in workspace: expected workspace package to exist". After some googling, that lead me to the following issues, and the various proposed solutions within:

• Failed to install dependencies in workspace: expected workspace package to exist yarnpkg/yarn#7807

  • Failed to install dependencies in workspace: expected workspace package to exist

  • Failed to install dependencies in workspace: expected workspace package to exist yarnpkg/yarn#7807 (comment)

    • yarn policies set-version 1.18.0

  • Failed to install dependencies in workspace: expected workspace package to exist yarnpkg/yarn#7807 (comment)

    • npx yarn-deduplicate && yarn install

  • CLI functionality related to aggregator preventing yarn commands 1.19-1.22 - Reverted to 1.16 yarnpkg/yarn#7734 (comment)

    • For those looking for a solution that doesn't involve changing the version of yarn you're using, editing package.json to include the version of the package you want and then running the yarn command again works just fine.

  • CLI functionality related to aggregator preventing yarn commands 1.19-1.22 - Reverted to 1.16 yarnpkg/yarn#7734 (comment)

    • For me, the problem is a regression 1.19.1->1.19.2 (as reported here). Downgrading to 1.19.1 helped.

  • CLI functionality related to aggregator preventing yarn commands 1.19-1.22 - Reverted to 1.16 yarnpkg/yarn#7734 (comment)

    • An alternative is to issue the command yarn policies set-version 1.19.1 from inside your project.

  • CLI functionality related to aggregator preventing yarn commands 1.19-1.22 - Reverted to 1.16 yarnpkg/yarn#7734 (comment)

    • You could also use lerna to add a package without downgrading the yarn version

    • npx lerna add <package>[@version] --scope=<workspace>

    • The command above will add the package to the specified workspace package.json and update yarn.lock

Playing around with things, this seems to be a working set of upgraded rollup version/plugins that still seems to produce the same build output for build/node_modules/react/umd/react.development.js.

Note that:

• It is using the last 1.x version of Rollup before Rollup 2.x
• It is using a version of @rollup/plugin-node-resolve below v13.0.0 as that requires Rollup 2.x
  • [@rollup/plugin-node-resolve] Fix required versions of Node/Rollup in README + include these breaking changes in CHANGELOG rollup/plugins#1222 (comment)
• The version of @rollup/plugin-node-resolve being used was determined by manually testing each version below 13.0.0 and trying to build yarn build react/index,react-dom/index --type=UMD. For versions 11.0.0 through to 11.2.1, the following error (presumably a bug in the resolver) was produced:

  • Error: Could not load /Users/devalias/dev/facebook/react/node_modules/react-dom/src/client/ReactDOMHostConfig (imported by /Users/devalias/dev/facebook/react/packages/react-reconciler/src/forks/ReactFiberHostConfig.dom.js): ENOENT: no such file or directory, open '/Users/devalias/dev/facebook/react/node_modules/react-dom/src/client/ReactDOMHostConfig'

Moving to a 2.x version of Rollup seems to change the output of build/node_modules/react/umd/react.development.js. While it may be insignificant, I figured it was worth calling out the differences here for posterity (partial diff included below):

I'm not currently sure if these changes are significant/change the semantics of the output, or are just a different way of the bundler working, but I did notice that it increases the output file sizes a bit (most dramatically in react.development.js):

⇒  yarn build react/index,react-dom/index --type=UMD
yarn run v1.22.19
$ node ./scripts/rollup/build.js react/index,react-dom/index --type=UMD
