The import statement is used to import functions, objects or primitives that have been exported from an external module, another script, etc.

Note: This feature is not implemented in any browsers natively at this time. It is implemented in many transpilers, such as the Traceur CompilerBabel or Rollup.


import defaultMember from "module-name";
import * as name from "module-name";
import { member } from "module-name";
import { member as alias } from "module-name";
import { member1 , member2 } from "module-name";
import { member1 , member2 as alias2 , [...] } from "module-name";
import defaultMember, { member [ , [...] ] } from "module-name";
import defaultMember, * as name from "module-name";
import "module-name";
Name of the object that will receive the imported values.
member, memberN
Name of the exported members to be imported.
Name of the object that will  receive the default export from the module.
alias, aliasN
Name of the object that will receive the imported property
The name of the module to import. This is a file name.


The name parameter is the name of the object that will receive the exported members. The member parameters specify individual members, while the name parameter imports all of them. name may also be a function if the module exports a single default parameter rather than a series of members. Below are examples to clarify the syntax.

Import an entire module's contents. This inserts myModule into the current scope, containing all the exported bindings from "my-module.js".

import * as myModule from "my-module";

Import a single member of a module. This inserts myMember into the current scope.

import {myMember} from "my-module";

Import multiple members of a module. This inserts both foo and bar into the current scope.

import {foo, bar} from "my-module";

Import a member with a more convenient alias. This inserts shortName into the current scope.

import {reallyReallyLongModuleMemberName as shortName} from "my-module";

Import an entire module for side effects only, without importing any bindings.

import "my-module";

Import multiple members of a module with convenient aliases.

import {reallyReallyLongModuleMemberName as shortName, anotherLongModuleName as short} from "my-module";

Importing defaults

It is possible to have default export (whether it is an object, a function, a class, etc.). Reciprocally, it is possible to use the import instruction to import such defaults.

The simplest version directly imports the default:

import myDefault from "my-module";

It is also possible to use the default syntax with the ones seen above (namespace imports or named imports). In such cases, the default import will have to be declared first. For instance:

import myDefault, * as myModule from "my-module";
// myModule used as a namespace


import myDefault, {foo, bar} from "my-module";
// specific, named imports


Importing a secondary file to assist in processing an AJAX JSON request.

// --file.js--
function getJSON(url, callback) {
  let xhr = new XMLHttpRequest();
  xhr.onload = function () { 
  };"GET", url, true);

export function getUsefulContents(url, callback) {
  getJSON(url, data => callback(JSON.parse(data)));

// --main.js--
import { getUsefulContents } from "file";
getUsefulContents("", data => {
