Unexpected Token Export: A Comprehensive Guide

The “unexpected token export” error happens as a result of this system’s module is incompatible with this system’s surroundings or the person has used the unsuitable technique to incorporate the JavaScript file into the HTML web page.Fix The Unexpected Token Export

By utilizing totally different strategies on this article, examples are mentioned to assist make clear the ideas and repair the problems. Let’s start!

Why Does a Program Show an Unexpected Token Export Error?

The program reveals an surprising token export error as a result of there’s a syntax error within the capabilities. Moreover, beneath are two main causes behind this program

  • Uncaught syntaxerror: Using the unsuitable ES6 Module syntax in a Node.js software.
  • Uncaught syntaxerror: Using the unsuitable ES6 Module syntax in a script.

– Uncaught Syntaxerror: Using the Wrong ES6 Module Syntax in a node.JS Application

Using the ES6 Module syntax with out “type” to “module” in bundle.json in a Node.js software will trigger this error message to happen. This implies that in a program, the kind property was not set to “module” within the bundle.json file.

Files that don’t finish with a .js extension will not be loaded as ES6 modules within the bundle.json file.Causes Of Unexpected Token Export

For instance:

// Uncaught SyntaxError: Unexpected token ‘export’

export class Person {

constructor(second) {

this.second = second;

}

}

– Uncaught Syntaxerror: Using the Wrong ES6 Module Syntax in a Script

Using the ES6 Module syntax with out setting sort to module within the script tag in a script program will trigger an error message to come up. The programmer didn’t set the kind of the <script /> tags to the module, as a result of which they obtained an error notification after this system’s execution.More Causes Of Unexpected Token Export

Moreover, the import of “exports” information is not going to be attainable both. Let us see an instance for higher understanding.

For instance:

<!DOCTYPE html>

<html lang=”en”>

<head>

<meta charset=”UTF-8″ />

</head>

<physique>

<script=”module” src=”index.js”></script>

</physique>

</html>

Explanation:

This program is unsuitable as a result of discover how there’s a syntax error in this system the place it’s written: <script=” module” src=” index.js”></script>. The program didn’t set the kind of the <script /> tags to module. Therefore, it brought on an error to happen.

– Syntax Error

Syntax errors can embrace perform errors in addition to the spelling of the instructions used. Syntax errors in a program not solely trigger a dateformat surprising token export error to happen but additionally another errors. Various comparable error sorts that happen as a result of syntax errors are:

  1. surprising token ‘export’ jest
  2. surprising token ‘export’ nextjs
  3. surprising token ‘export’ nuxt
  4. surprising token ‘export’ react
  5. surprising token ‘export’ angular
  6. surprising token ‘export’ vue

How To Resolve an Unexpected Token ‘Export’ Error?

You can resolve an surprising token ‘export’ error message utilizing varied efficient strategies corresponding to setting the kind property to “module” in your program, correctly importing the category in one other file and utilizing the right syntax to jot down the code.

– “Type” Property Set to “Module” within the bundle.json Folder

To resolve the uncaught syntaxError surprising token ‘export’ error, the programmer has to alter the kind property to “module” of their bundle.json file. The information ending with a “.js” extension include ES6 modules.Solutions For Unexpected Token Export

If the programmer doesn’t have this bundle.json file, they will create one through the use of the “npm init -y” command. Furthermore, open the terminal within the challenge’s root listing and use this command: “npm init -y”. Now proceed by altering the kind property within the bundle.json folder to “module”. Let’s see the next instance:

{

“type”: “module”,

“name”: “javascript”,

“version”: “1.0.1”,

“description”:” “,

“main”: “index.js”,

“scripts”: {

“keywords”: []

},

“test”: echo ”Error: no check specified” && exit 1”

“license”: “ISC”,

“author”:”’,

}

Now, the programmer can use the ES6 module syntax of their Node.js software. Use the next syntax:

export class Person {

constructor(second) {

this.second = second;

}

}

– Properly Import the Class Into Another File

After analyzing and correcting the above steps, the programmer ought to attempt to import the category into one other file through the use of the right technique. Here is how the programmer can import the category in one other file:

Example:

import {Man} from ‘./another-file.js’;

const p2 = new Man (‘Amir’);

console.log(p2);

Setting the kind property within the bundle.json file to module will enable the programmer to make use of ES6 modules of their Node.js software. By following the above syntax, the error message shall be eliminated.

– Use the Common.js Syntax

In order to unravel the “Uncaught SyntaxError Unexpected token ‘export’” error message, the programmer ought to refactor their code to make use of the CommonJS syntax, which is: “module.exports = {num};”. They ought to keep away from utilizing the “export num = 10;” .command. Let’s use an instance to grasp.

Example:

class Female {

constructor(second) {

this.second = second;

}

}

module.exports = {

Female,

};

After doing this, the programmer is then capable of import members of different information utilizing the require() perform. For this, use the syntax beneath:

const {Male} = require(‘./index.js’);

Explanation:

Usually, the error happens as a result of the programmer will not be allowed to make use of the syntax of the ES6 Module in Node.js but. There are a number of methods to resolve this and get permission to make use of the ES6 module syntax.

For instance, use babel to transpile the ES6 code to an older model of JavaScript or simply refactor the code to the CommonJS syntax, as proven above within the instance.

– Solving Uncaught Syntaxerror Unexpected Token ‘Export’ in Browser

In order to unravel the “Uncaught SyntaxError Unexpected token ‘export’” error, the programmer ought to set the kind of their <script /> tags to module. For instance, <script sort=”module” src=”index.js”></script>.

The sort= “module” attribute is supported in all fashionable browsers. It additionally permits programmers to make use of the syntax of the ES6 module.

Example:

<!DOCTYPE html>

<html lang=”en”>

<head>

<meta charset=”UTF-8″ />

</head>

<physique>

<script sort=”module” src=”index.js”></script>

</physique>

</html>

By following the syntax above, this system will allow the programmer to make use of the syntax of the ES6 module of their index.js file. See the next instance:

For instance:

// Works

export class Male {

constructor(second) {

this.second = second;

}

}

Explain:

As lengthy because the programmer makes use of the “set the type” attribute to “module” when loading their scripts, they’re able to use the syntax of the ES6 module. Moreover, the programmer will simply eliminate an surprising token ‘export’ typescript error message by following this syntax.

– Import the Exports of Other Files Using the Proper Script Function

Nowadays, all fashionable browsers assist the ‘type=” module”’ attribute. After following the steps above, the programmer can import different information’ exports. Use the next ES modules syntax given beneath:More Solutions For Unexpected Token Exporte

Syntax:

import {Male} from ‘./index.js’;

console.log(Male);

Note that the programmer has to set the kind attribute to the module on all scripts that use the ES Modules syntax. In order to do this, see the next instance.

Example:

<!DOCTYPE html>

<html lang=”en”>

<head>

<meta charset=”UTF-8″ />

</head>

<physique>

// sort is ready to ‘module’

<script sort=”module” src=”index.js”></script>

<script sort=”module” src=”another-file.js”></script>

</physique>

</html>

– Use the ES6 Modules Syntax With Default Exports

It is essential to know that the programmer ought to use the right ES6 modules syntax with default exports. Here are some examples of utilizing the syntax of the ES6 module with named or default exports.

Named exports utilizing ES6 modules are:

export class Male {}

export class Female {}

– Have Only One Default Export per File

The programmer can solely have one default export per file through the use of ES6 modules. Its syntax is export default class Male {}. Now, proceed to import this in one other file. For that, the syntax is:

import Person from ‘./index.js’.

The programmer may combine and match. However, the one export per file rule additionally needs to be adopted right here. Let’s see an instance:

Example:

export default class Male {}

export const age = 28;

Now, the programmer can import each exports in one other file. Use the next command syntax:

import Male, {age} from ‘./index.js’

Conclusion

After studying this information completely, the reader ought to have gained sufficient understanding of this error and will be capable of determine the causes and fixes. Here’s a fast recap:

  • Syntax errors may cause the identical difficulty to come up as nicely. For instance, Uncaught SyntaxError: Unexpected token export.
  • When attempting to import an area javascript within the challenge, an error can come up. Therefore, don’t neglect to declare the kind of module the person shall be utilizing.
  • To declare the kind of module correctly, add a script tag within the index.html folder/file. This will make the error disappear.

The programmer can use this information to grasp clear up such varieties of errors and use it of their packages. Thank you for studying!
