babel-plugin-import

What is babel-plugin-import?

babel-plugin-import is a Babel plugin for modular import of components, enabling on-demand loading of specific parts of a library. This can help reduce bundle sizes by only including the necessary parts of a library in the final build.

What are babel-plugin-import's main functionalities?

Importing specific components

This feature allows you to import specific components from a library like 'antd' without importing the entire library. The configuration in babel.config.js specifies the library name, directory, and style options. The import statement in the JavaScript file then only includes the 'Button' component.

/* Babel configuration (babel.config.js) */
{
  "plugins": [
    [
      "import",
      {
        "libraryName": "antd",
        "libraryDirectory": "es",
        "style": "css"
      }
    ]
  ]
}

/* Usage in a JavaScript file */
import { Button } from 'antd';

Customizing import paths

This feature allows you to customize the import paths for libraries like 'lodash'. The configuration in babel.config.js specifies the library name and options like 'camel2DashComponentName' to control the import path format. The import statement in the JavaScript file then only includes the 'debounce' function.

/* Babel configuration (babel.config.js) */
{
  "plugins": [
    [
      "import",
      {
        "libraryName": "lodash",
        "libraryDirectory": "",
        "camel2DashComponentName": false
      },
      "lodash"
    ]
  ]
}

/* Usage in a JavaScript file */
import { debounce } from 'lodash';
