Some config updates required here for how we use the runtime

blowery · 2018-08-09T18:05:36Z

We need to pick up upgrades to everything else that depends on @babel/runtime to land this.

@babel/runtime used to include core-js as part of the package, but in b56, they split it out to @babel/runtime-corejs2. Packages like @wordpress/api-fetch have dependencies like "@babel/runtime": "^7.0.0-beta.52", which automatically moves to beta.56, which is now incompatible.

So we either need to pick up upgrades to all of the @wordpress/* packages that spec @babel/runtime-corejs2 as a dependency and use it that way, or an update to those packages that caps the dependency at beta.55.

babel.config.js

 				regenerator: false,
+				useESModules: false,


Why not use Babel helpers with import/export syntax by enabling useESModules?

The useESModules: true indeed looks interesting: the Babel helpers (i.e., node_modules/@babel/runtime/helpers/esm/inherits.js) are then imported in a ES6 module rather than CommonJS version. There is negligible impact on build size though.

Right, given that polyfills are off, it probably doesn't matter.

There is one failing test, investigating.

There is one failing test, investigating.

Funny bug with mocked window.FileList. It's an array with a mocked prototype, so that files instanceof window.FileList in the tested code returns true.

But it's still partially an array: Array.isArray() returns true for it, probably because its toString method still returns [object Array].

Before the Babel upgrade, code

if ( files instanceof window.FileList ) {
  files = [ ...files ];
}

transpiled to files = toConsumableArray( files ). The helper managed to convert the "almost array" to "real array".

But after the upgrade, the toConsumableArray helper is no longer used and tests running in Node don't transpile the [ ...files ] expression at all. Now it becomes a problem that the mocked FileList object doesn't expose a Symbol.iterator property.

I pushed a patch that adds the iterable capability to the mock.

blowery

LGTM!

jsnajdr · 2018-08-28T14:41:30Z

@blowery @gziolo If we merge this without coordinating with Gutenberg packages, can something bad happen? Like versions of runtimes or polyfills getting out of sync and duplicated?

gziolo · 2018-08-28T19:04:02Z

Gutenberg is on beta-56, which is the last version before rc. I guess it’s going to be fine. I didn’t find any issues when upgrading to 7.0.0 stable.

Makes the mocked FileList object created in the test iterable and therefore a valid input to `[ ...files ]` spread operator. Before Babel 7.0.0, the bug was covered up by Babel's `toConsumableArray`, because for the mocked object, `Array.isArray` still returns true.
