babel-plugin-short-import

Small Babel plugin allowing to use shorthand imports.

It generates import's identifier from file name (without extension), so all line can be written in shorter version as import "path/to/the/file". It also works with NPM modules.

Plugin requires Babel 7 and it may cause conflicts with Webpack's methods of including styles and other files.

Installation

$ npm install --save-dev babel-plugin-short-import

Usage

Via .babelrc (Recommended)

.babelrc

{
  "plugins": [
    "babel-plugin-short-import", 
    { 
      "importAsNamespace": false,
      "useCamelCase": false
    }
  ]
}

Via CLI

$ babel --plugins babel-plugin-short-import script.js

Via Node API

require('babel-core').transform('code', {
  plugins: [
    'babel-plugin-short-import', 
    { 
      importAsNamespace: false,
      useCamelCase: false
    }
  ]
});

Parameters

• importAsNamespace

  If false (default) it will behave like import file from "./path/file.js".

  Otherwise it will import all namespace - import * as file from "./path/file.js".

• useCamelCase

  If false (default) it will replace invalid characters in file name with underscore ( _ ) like import my_file from "./path/my-file.js.

  Otherwise it will apply camel case - import * as myFile from "./path/my-file.js".

Examples

path/to/the/file.js or @vendor/some-module

  export const test1 = "Test 1";
  export const test2 = { test: 2 };
  export default "Default test";

Default importing

Configured with { "importAsNamespace": false }

Import in this example is an equivalent of import file from "path/to/the/file.js"

import "path/to/the/file.js";
 
console.log(file.test1); // undefined
console.log(file.test2); // undefined
console.log(file); // "Default test"

Namespace importing

Configured with { "importAsNamespace": true }

Import in this example is an equivalent of import * as file from "path/to/the/file.js"

import "path/to/the/file.js";
 
console.log(file.test1); // "Test 1"
console.log(file.test2); // { "test": 2 }
console.log(file); // { "test1": "Test 1", "test2": { "test": 2 }, "default": "Default test" }

NPM modules importing

Configured with { "importAsNamespace": true, "useCamelCase": true }

import "@vendor/some-module";
 
console.log(someModule.test1); // "Test 1"
console.log(someModule.test2); // { "test": 2 }
console.log(someModule.default); // "Default test"
