Unable to catch SyntaxError: Cannot use import statement outside a module

One of the common ways to avoid the syntax error: cannot use import statements outside a module is to use module or script tag.

In case of loading the script or fetching the SCR file alone instead of multiple files from the dist folder, the uncaught syntax error: cannot use import statement outside a module will likely show up on your screen.

This could be a common mistake or one of the primary reasons for displaying the error if you have forgotten to add the type= “module” attribute.

Not only limited to this, but other multiple reasons cause up the error and for that multiple solutions too. Deciphering the situation, you can use the best possible solution and get rid of the error within some seconds.

Why does the Uncaught Syntax Error: Cannot use the import

statement outside a module occur?

As said, there are multiple reasons and multiple solutions, so let’s find out and solve the error in no time.

#1: If working on server-side or client-side browsers:NODE.JS

The uncaught syntax error: cannot use import statements outside a module occurs irrespective of your working side. The error may occur when you’re dealing with JavaScript on the server-side with Node.js or client-side in the browser.

The error further can be related to modules when switching from requiring import to Node js. By standard, it uses CommonJS modules that ensure the use of (…) import external dependencies.

Related to some of the triggers, the error must be avoided. The trigger has a connection with the attempt to copy and paste an import statement from an npm readme document.

The trigger will be executed. As of now, the import won’t work out of the box. Hence the error will be activated.

Quick fix: To enable support for ES modules (e.g., import) in Node.js:

1. To avoid the upcoming error, change the file from js to .mjs.

2. Now add or replace “”type””: “”module”” in your package.json file.

3. Proceed and process your node scripts with the –input-type flag set to the module: node –input-type module.

You are suggested to adjust the way your scripts work. The file should be considered the Real module allotted with exporting for consuming files.

What if you encounter another error to avoid?

The “ReferenceError: require is not defined” is likely to show up if the file attempts to use both import and require module patterns, which can never happen at all. You can use one at once.

Replace the matching statements with Imports:
const { host, port } = require(‘./config’);

To allow the import to work:
import { host, port } from ‘./config’;

#2: If you are working on OS, then you are doing this wrong

A module’s source is usually in the src/ folder, so if the URL of the script you’re uploading contains “src/,” then you are using the source code in an unmodified/unlinked condition and getting rid of the errors that need to be corrected.

Packages come in bundled versions because they use rollup packages or something similar to create them.

Quick Fix:

If you are trying to import a non-module npm package as a module, but it’s been well-defined globally on the window. Then it would help if you looked out for an “es” port of the package.

For example: work with the dash-es npm package instead of lodash to use ES6 imports for individual functions.

#3: Adding type=” ” module”” Attribute To The Script Tag

Another reason for the error to pop out is loading scripts from the src directory instead of the files inside the dist directory.

In simpler terms, it will probably result in your src file being written in es6 and not compiled as a standard js file.

Dist files usually contain associated and compiled JavaScript files, so it is recommended to use the dist folder instead of src.

Quick Fix: “Type=Module”
<script type=”module” src=”some_script.js”></script>

Or you need to replace <script src=”../src/main.js”></script> to <script

type=”module” src=”../src/main.js”></script>

Conclusion:

We hope that you have received some insights and learned how to avoid the uncaught syntax error with our article: cannot use import statement outside a module error must be solved by now.

As said, there are multiple ways and multiple techniques to avoid the upcoming error; you can use any one of the techniques as mentioned above to avoid the graphic display of the error.

There isn’t any hard and fast rule or specific instructions that should be kept in mind to avoid the upcoming error.

Additionally, it is always recommended to be careful while adding the statements and ensure that the syntax and code of your typing must be entirely correct.

Faqs:

What is a module in JavaScript?

The small blocks of independent, reusable code that can be used as building blocks when creating non-critical Javascript applications is called a Module.

A module allows developers to define private and public members separately, making it one of the most desirable and easy-to-use design patterns in the JavaScript paradigm.

Can I use imports in JavaScript?

The Javascript import statement is used to import bindings exported from other modules. When using imports, code is more manageable if it is made up of small, tiny pieces.

This is the idea of ​​keeping functionality in only one task or having a file containing only a few or one component at a time.

What should I do if I encounter other errors during the process?

When working with the Import ES Module and JavaScript Module statements in the browser, you must explicitly tell the browser that your script is a module.

For this, you need to add type=” ” module” to any [removed] tags that point to JS modules. That way, you can import this module without any problems.
