swc-plugin-transform-cx-imports

swc-plugin-transform-cx-imports

Having improved performance, this plugin replaces babel-plugin-transform-cx-imports.

What is this plugin used for?

• Rewrites Cx imports to use src files which may result in smaller builds:

import { TextField } from 'cx/widgets'

becomes

import { TextField } from 'cx/src/form/TextField'

• Includes SCSS files for imported components (experimental):

import { TextField } from 'cx/widgets'

also adds

import 'cx/src/form/TextField.scss'

Installation

• Install the package using the yarn add swc-plugin-transform-cx-imports command. This plugin requires another plugin, which you can install using the yarn add swc-plugin-transform-cx-jsx.

• Inside the webpack.config.js file, import manifest from 'cx/manifest' - const manifest = require('cx/manifest');, and replace babel-loader with swc-loader:

{
  loader: 'swc-loader',
  options: {
    jsc: {
        loose: true,
        target: 'es2022',
        parser: {
          syntax: 'typescript',
          decorators: true,
          tsx: true,
        },
        experimental: {
          plugins: [
              [
                require.resolve('swc-plugin-transform-cx-jsx/swc_plugin_transform_cx_jsx_bg.wasm'),
                { trimWhitespace: true, autoImportHtmlElement: true },
              ],
              [
                require.resolve('swc-plugin-transform-cx-imports/swc_plugin_transform_cx_imports_bg.wasm'),
                { manifest, useSrc: true },
              ],
          ],
        },
        transform: {
          react: {
              pragma: 'VDOM.createElement',
          },
        },
    },
  },
}
