prettier added parentheses, @BSFishy can you check if they were supposed to be added? If they shouldn't, I'll revert the prettier changes

What caused this change? I don't see any changes to anything related to Prettier. Is the file just not included in linting checks?

I don't see any issue with adding this change. It will keep our code style more consistent. I just want to know what caused it :)

I just enabled Prettier in the settings of my IDE, it seems that Prettier was not applied to some files in the script folder before, f.e.

scripts/babel/fetch-i18n-strings.js scripts/babel/react-docgen-typescript.js scripts/eslint-plugin/forward_ref_display_name.js scripts/eslint-plugin/i18n.js

and etc.

i am glad to see you are using a real IDE... unlike some people... 😉 at Ashwin.

Eslint started not passing due to the detection of errors like the following

68:30 error Unable to resolve path to module './search?raw' import/no-unresolved

This may be due to the fact that these files were indexed, but I'm not sure. If you go into the code locally in another branch, IDE will also show the same error. I haven't found a more elegant solution to fix this error, so I turned off the rule.

Is there an option to ignore query params? Maybe we could raise this to the ESLint team? Otherwise we could create a follow up issue to dive deeper into this

As it turned out, eslint-import-resolver-webpack only supports "synchronous" Webpack configs (https://github.com/import-js/eslint-plugin-import/tree/main/resolvers/webpack). How critical is it to use getPort? Is it possible to just put port 8030?

I'm pretty sure the reason for getPort is that you can actually have multiple instances of OUI running on different ports - you can replicate by doing yarn start in multiple terminal tabs/windows, and the port will auto increment without collisions.

In my testing, this line needed to be changed to

corejs: process.env.NO_COREJS_POLYFILL ? undefined : 3,

I think because it doesn't want the corejs version unless 'usage' is specified for useBuiltIns. Did you run into the same thing at all?

Just confirmed, a warning pops up when this line isn't changed:

WARNING (@babel/preset-env): The `corejs` option only has an effect when the `useBuiltIns` option is not `false`

corejs: process.env.NO_COREJS_POLYFILL ? undefined : 3,

I'm not sure about changing false to undefined because there is no difference between them. According to the documentation, the default value for useBuiltIns is false (https://babeljs.io/docs/babel-preset-env#usebuiltins). I guess it is worth leaving false because using values that are expected by the field will help avoid surprise issues in the future.

I think because it doesn't want the corejs version unless 'usage' is specified for useBuiltIns. Did you run into the same thing at all?

Yes, I get the same warning message. The reason for this is that we purposely do not include polyfill imports in our build (see https://github.com/opensearch-project/oui/blob/main/scripts/compile-oui.js#L190-L219). As far as I understand, this solution was inherited from here elastic/eui#1982.

Can any of you help me with why we need any polyfills?

I checked the code of babel/preset-env and @BSFishy's solution is a valid one.

Summary of Work Done

Dependencies

Bumped webpack from v4 to v5
Bumped postcss from v7 to v8
Bumped babel minor version
Bumped typescript from v4.0.5 to v4.1.6 ([CCI] Update webpack to v5 #770 (comment))
Removed some of the resolutions that were covered by a dependency update

Formatting

Prettier was not applied to some files in the script folder before, so the changes can be found in the following files (#770 (comment))

scripts/babel/fetch-i18n-strings.js
scripts/babel/react-docgen-typescript.js
scripts/eslint-plugin/forward_ref_display_name.js
scripts/eslint-plugin/i18n.js

Questions Requiring Further Discussion

Can we directly use port 8030 instead of utilizing getPortSync and getPort.makeRange?

During our migration to webpack v5, we ran into a problem with deasync, as it stopped working. Previously, it was used to convert our webpack.config.js from asynchronous to synchronous. However, since webpack supports asynchronous configurations, I've converted our config file accordingly. However, this change introduced a bottleneck.

As part of our adherence to best practices, the legacy !!raw-loader! syntax has been replaced with ?raw, such as:

const basicSource = require('!!raw-loader!./basic_window_event');
// is now
const basicSource = require('./basic_window_event?raw');

You can read more about this transition in the Webpack documentation.

However, we ran into a problem: eslint does not recognize resourceQuery. This is because eslint-import-resolver-webpack only supports synchronous webpack configurations (see here), while we are using an asynchronous one. Since deasync is no longer working in webpack.config.js, we can't go back to it.

To address this, we could potentially switch back to a synchronous configuration in our webpack.config.js. This could be accomplished by eliminating the use of getPortSync and using port 8030 directly. Would it be possible to simply use port 8030 instead of getPortSync and getPort.makeRange?

TypeScript refuses to export the Query class from index.ts for reasons that remain unclear. See the specific issue in the [code here].

The system throws the following warning message:

WARNING in ../../src/components/search_bar/search_bar.tsx 256:39-44
export 'Query' (imported as 'Query') was not found in './query' (possible exports: AST)
 @ ../../src/components/search_bar/index.ts 31:0-49 31:0-49 31:0-49

 @ ./routes.js 56:0-56 205:44-60
 @ ./index.js 42:0-30 58:28-47

For now, the issue has been resolved by importing the Query class from query/query.ts, instead of from query/index.ts.

There is a chance that a future update of the `TypeScript' version may have a fix for this problem.

Running into a complex type conflict with searchProps in OuiSelectable

We've encountered a type conflict problem with searchProps in the OuiSelectable component that is proving difficult to resolve. Details about the specific type error can be found here.

This problem is currently solved by using the @ts-ignore. There is a chance that a future update of the `TypeScript' version may have a fix for this problem.

Thinking about this more, could it be possible that the sass-vars-to-js-loader loader is using some sort of Webpack 4 structure and the reason why the charts module doesn't export anything?

AMoo-Miki · 2023-09-28T06:52:16Z

A few observations, after rebasing and resolving conflicts:

The updated autoprefixer causes duplicate CSS. I am not worried about this because i will be porting some changes from OSD that will eliminate the need for autoprefixer.
*.min.css files are no longer minified. postcss and cssnano have both been bumped but I didn't dig to see which portion is breaking the logic.
oui.js is 1.5MB larger; doesn't sound right and more investigation is needed.
oui.min.js, oui.min.js.LICENSE.txt, oui.min.js.map fail to generate.
*ui_charts_theme.js are generated as folders and not files.

I have pushed the rebased code to AMoo-Miki@ddf16ef.

AMoo-Miki · 2023-09-29T21:58:44Z

Fixed the minification:

Had to disable cssDeclarationSorter because it could have been unsafe.
The new cssnano merges back-to-back media queries and removes the media queries for the lower boundary; verified that it was safe.
The new cssnano also doesn't break and combine neighboring definitions.
rgba is converted to hsla; shouldn't be a big deal.
svgo produces slightly longer assets.

BSFishy · 2023-09-30T17:48:17Z

svgo produces slightly longer assets.

But the assets generated by svgo should all be in separate files right? All OUI icons are loaded in async, and won't be in the main bundle, right?

OUI inlines them :/

postcss.config.js has postcss-inline-svg defined in it. However, the ones I saw elongated are those that it finds in imported deps.

AMoo-Miki · 2023-10-01T00:20:20Z

In an attempt to dig deeper into why the JS files were larger with webpack5, i split the eui_charts_theme.js files, before (260KB) and after (363KB). I see a lot more imports from corjs included with webpack5; 57 files totaling 100KB. These include stuff like:

../node_modules/core-js/internals/array-from.js
../node_modules/core-js/internals/iterator-define.js
../node_modules/core-js/internals/regexp-exec.js
../node_modules/core-js/modules/es.symbol.constructor.js

Also, one almost 5KB is wasted due to two indented copyright headers!

I suspect the same is happening with oui.js too.

My latest stuff can be found at https://github.com/AMoo-Miki/oui/tree/updated-webpack-5.

AMoo-Miki · 2023-10-01T01:16:05Z

With oui.js:

1.5MB was added.
197 imports of 461KB are removed.
- some removed imports are index.ts and types.ts files that only re-exported stuff:
```
./components/delay_hide/index.ts
./services/color_picker/index.ts
./services/popover/index.ts
```
62 imports of 214KB are added.
- imports from assert make up 114KB of that.
- 15 are from corejs worth 20KB.

1919 files have some kind of change in them, resulting in the 1.7MB delta:

Numerous files (i stopped counting at 50 of the first 100) have gained 5KB-10KB, all because of lines like:

/* harmony import */ var core_js_modules_es_array_slice_js__WEBPACK_IMPORTED_MODULE_21__ = __webpack_require__(/*! core-js/modules/es.array.slice.js */ "../node_modules/core-js/modules/es.array.slice.js");
/* harmony import */ var core_js_modules_es_array_slice_js__WEBPACK_IMPORTED_MODULE_21___default = /*#__PURE__*/__webpack_require__.n(core_js_modules_es_array_slice_js__WEBPACK_IMPORTED_MODULE_21__);

by the way, i couldn't get the docs to work. yarn start shows a blank page.

From CI, it looks like there's still reference to raw-loader: https://github.com/opensearch-project/oui/actions/runs/6177159690/job/16767685139?pr=770#step:5:31
