parcel is support~

@crazyair just tried this example, it seems to work for me: https://github.com/PlasmoHQ/examples/tree/main/with-ant-design

The tilde import means from the root of the current project for Plasmo (and latest Parcel), NOT from node_modules: https://docs.plasmo.com/workflows/faq#tilde-import-resolution

[crazyair]

~ It is used in the external package,Not in this project.

[louisgv]

can you give me the project you're trying to use? Or is it antd itself?

[louisgv]

Also, if they use ~ internally, that project should really bundle their style instead of exporting raw less (i.e, you should use the css file as end-user). I don't see the benefit of using less that way - bundle is the same?

[crazyair]

You can install @ant-design/pro-components in with-ant-design

popup.tsx

import { ProCard } from '@ant-design/pro-components';

<ProCard title="默认尺寸" extra="extra" tooltip="这是提示" style={{ maxWidth: 300 }}>
    <div>Card content</div>
    <div>Card content</div>
    <div>Card content</div>
</ProCard>

This is a "missing feature" within Parcel's less transformer: https://github.com/parcel-bundler/parcel/blob/v2/packages/transformers/less/src/LessTransformer.js#L115 OR more likely, inconsistency with parcel's definition of the ~ tilde path.

Some potential solutions:

1. Fix the less transformer linked above to parse internal ~ from node_modules (do a package.json lookup to ensure it always resolve to the root of its specific module).
2. Fix https://github.com/ant-design/pro-components/blob/master/packages/card/src/components/Actions/index.less and all of their component to NOT use ~, or if they do, replace them with non-tilde path on publish

@crazyair can you link me the doc for the tilde path import in less? Also, would you be down to investigate and implement a solution?

[louisgv]

parcel-bundler/parcel#907 (comment) parcel is support~

NOTE: These examples you're referencing uses parcel@1.x (same with the antd example). As of 2.x, parcel has its own definition of ~ and thus broke this less feature.

external project Deleting ~, an error will be reported

@import '~antd/dist/antd.less'; to @import 'antd/dist/antd.less';

Do you have the lessrc option in your project?

[crazyair]

Do you have the lessrc option in your project?

The main project has, but the external project does not

[louisgv]

Can you do a bundling of the external project into some plain component, and just import the output inside plasmo and use it that way then?

[louisgv]

Only one path is referenced， lib or es.

you can import directly like @import 'antd-pro/dist/some-pro-comp';

[crazyair]

I've tried everything but still haven't solved it 😭

no dist，need change less variable

^ There's a dist directory if you installed the specific pro-card package

have you tried hacking the less transformer? Basically, make it align with the way webpack bundle less source as antd. Also I have no idea how other project uses antd-pro unless they have a similar webpack bundler OR postcss plugin to reconfigure those paths.

[crazyair]

No problem with webpack or umi

[louisgv]

@crazyair in Umi for it to work with latest antd-pro, you also need to hack up the less path on webpack config:

https://v3.umijs.org/guide/upgrade-antd-pro-to-umi-3#%E9%85%8D%E7%BD%AE%E5%B1%82%E8%BF%81%E7%A7%BB

So yeah for it to work with parcel, you will need to play around with the less transformer as well and maybe handle the antd special case, OR if antd managed to make their convention widespread enough, implement it as default

[crazyair]

How is parcel configured and can it be built-in?

[louisgv]

Yes, see this comment: #143 (comment)

[crazyair]

Second, I've tried, but I can't

[xudaolong]

@crazyair I encountered the same problem, the solution is parcel-bundler/parcel#6623 (comment)

node_moudles ? no

[xudaolong]

@crazyair You can use a script similar to the one executed after postinstall.

const fs = require("fs-extra")

const previous = {
  same: [
    // ISSUE: https://github.com/PlasmoHQ/plasmo/issues/143
    [
      "node_modules_cover/less/default-options.js",
      "node_modules/.pnpm/less@4.1.3/node_modules/less/lib/less/default-options.js"
    ]
  ]
}

;(async () => {
  ;[...previous["same"]].map(([source, target]) => {
    fs.copy(source, target)
      .then(() => console.log(`${target}: load success`))
      .catch((err) => console.log(err))
    return null
  })
})()

[crazyair]

My question is~xxx.less

[louisgv]

Yeah this doesn't seem to solve the nested ~ issue ;d...
