babel-plugin-remove-import-export

A babel plugin to remove import and export declaration in the source file.

This will be useful if you just want to provide a code snippet without the extra module syntex, for example LeetCode.

Warning: This plugin will break the context of the script, use with caution.

Example

import { LinkedList } from 'some-lib';

function foo() {
  return new LinkedList(['bar']);
}

export class Solution {
  add(a, b) {
    return a + b;
  }
}

export default foo;

Out

function foo() {
  return new LinkedList(['bar']);
}

class Solution {
  add(a, b) {
    return a + b;
  }
}

Installation

yarn add -D babel-plugin-remove-import-export

Or, use npm:

npm install babel-plugin-remove-import-export --save-dev

Usage

Via `.babelrc` (Recommended)

.babelrc

// without options
{
  "plugins": ["remove-import-export"]
}

// with options
{
  "plugins": [
    ["remove-import-export", {
      "removeImport": false,
      "removeExport": false,
      "removeExportDefault": false,
      "preseveNamedDeclaration": false
    }]
  ]
}

Via CLI

babel --plugins remove-import-export script.js

Via Node API

require("@babel/core").transform("code", {
  plugins: ["remove-import-export"]
});

Options

`removeImport`

boolean, defaults to true.

`removeExport`

boolean, defaults to true.

`removeExportDefault`

boolean, defaults to true. Set this option to false will preserve the default export.

`preseveNamedDeclaration`

boolean, defaults to true.

<summary>Example</summary> Set preseveNamedDeclaration to false will not keep the declaration after export keyword. In

javascript
  function foo() {
    return 'bar';
  }

  export class Solution {
    add(a, b) {
      return a + b;
    }
  }

javascript
  function foo() {
    return 'bar';
  }
