Another wasm swc transform imports plugin
npm install swc-plugin-another-transform-imports

Another wasm plugin for swc, inspired from babel-plugin-transform-imports.
``bash`
npm install --save-dev swc-plugin-another-transform-importsor
yarn add -D swc-plugin-another-transform-imports
It follows resolving rule of node.js, can be use in .swcrc,webpack.config.js or next.config.js and so on. For Example:
`json`
{
"jsc": {
"experimental": {
"plugins": [
[
"swc-plugin-another-transform-imports",
{
"antd": {
"transform": "antd/lib/${member}",
"skipDefaultConversion": false,
"preventFullImport": true,
"style": "antd/lib/${member}/style",
"memberTransformers": ["dashed_case"]
},
"lodash": {
"transform": "lodash/${member}",
"preventFullImport": true
}
}
]
]
}
}
}
Can convert the following lines:
`js`
import { Button as MyButton, BackTop } from "antd";
import { merge } from "lodash";
To:
`js`
import MyButton from "antd/lib/button";
import BackTop from "antd/lib/back-top";
import "antd/lib/back-top/style";
import "antd/lib/button/style";
import merge from "lodash/merge";
Since the semantic version association of @swc/core (npm) and swc_core (rust) for next.js or rspack is still experimental. next.js and rspack has a lot of breaking change in the swc native plugin mechanism between major and even minor versions.
It is possible that as next.js and swc are updated, the current plugin will fail in the new version. Hopefully the new plugin api for swc will be stable soon. Here is the current version correspondence.

Ensure you read next.js compiler docs first!!!!
antd/es/xxx/style and antd/lib/xxx/style will introduce less, please add less-loader by yourself.
If you use antd and next.js at the same time, it will be a bit troublesome to work with them, you can use next-plugin-antd-less for convenience, see issue 1 for an example.
| Name | Type | Required | Default | Description |
| ----------------------- | -------------------------- | -------- | ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| transform | string | yes | undefined | The library name to use instead of the one specified in the import statement. ${member} will be replaced with the member, aka Grid/Row/Col/etc. |preventFullImport
| | boolean | no | true | Whether or not to throw when an import is encountered which would cause the entire module to be imported. |skipDefaultConversion
| | boolean | no | false | When set to true, will preserve import { X } syntax instead of converting to import X. |style
| | string | no | false | The style path of the member, ${member} will be replaced with the member, aka Grid/Row/Col/etc. |memberTransformers
| | Array | no | [] | Member transformers |

Usually upgrading to the latest version of @swc/core and other swc tools will solve the problem, see the following issue for typical solution:
1. plugin-styled-components crashes with 'Error while importing "env"."\_\_get_transform_plugin_config": unknown import.'
2. about next.js and antd
3. about next.js 13+
You can simply fork this plugin, modify its source code to suit your custom needs. For fast validation, you don't necessarily have to publish the modified project, but simply require your wasm file to the project. For example:
`bash`
cargo prepublish
or
`bash`
npm run prepublish
Then copy your wasm target file, and set your config to:
`js``
module.exports = {
...,
"jsc": {
"experimental": {
"plugins": [
[
require.resolve("./path/to/your-modified-plugin.wasm"),
{
..your options
}
]
]
}
},
...
}
