Attempted import error 'X' is not exported from [Solved]

# Attempted import error 'X' is not exported from

The React.js "Attempted import error 'X' is not exported from" occurs when we try to import a named import that is not present in the specified file.

To solve the error, make sure the module has a named export and you aren't mixing up named and default exports and imports.

Here is an example of how the error occurs. This is a file that exports a function.

Copied!
// 👇️ Note: default export
export default function sum(a, b) {
  return a + b;
}

And this is our index.js file where we import the function.

Copied!
// ⛔️ Attempted import error: 'sum' is
// not exported from './another-file'.
// 👇️ Note: using named import
import {sum} from './another-file';

console.log(sum(5, 10));

Notice that in another-file.js we used a default export and in the index.js file we used a named import. This is the reason the error occurs.

To solve the error, make sure:

1. To wrap named exports in curly braces when importing them
2. Use the default keyword when exporting a value as a default export
3. Each module only has a maximum of 1 default export but could have multiple named exports

# Solve the error using named exports

Here is an example of how to solve the error using a named export.

Copied!
// 👇️ Using named export
export function sum(a, b) {
  return a + b;
}

And import the function in the index.js file.

Copied!
// 👇️ Using named import
import {sum} from './another-file';

console.log(sum(5, 10));

Notice that we don't use the default keyword for named exports and wrap a named import in curly braces.

# Solve the error using a default export

Here is an example of how to solve the error using default export and import.

Copied!
// 👇️ default export
export default function sum(a, b) {
  return a + b;
}

And now we use a default import in the index.js file.

Copied!
// 👇️ default import
import sum from './another-file';

console.log(sum(5, 10));

Notice that we do not use curly braces when working with default imports.

If you are exporting a variable as a default export, you have to declare it on 1 line and export it on the next. You can't declare and default export a variable on the same line.

Copied!
// 👇️ default export
const example = 'hello world';

export default example;

You can also mix and match, here's an example.

Copied!
// 👇️ default export
export default function sum(a, b) {
  return a + b;
}

// 👇️ named export
export const num = 15;

And here are the imports.

Copied!
// 👇️ default and named imports
import sum, {num} from './another-file';

console.log(sum(num, 10));

We used a default import to import the sum function and a named import to import the num variable.

# Conclusion

To solve the error, be consistent with your ES6 imports and exports.

If a value is exported as a default export, it has to be imported as a default import and if it's exported as a named export, it has to be imported as a named import.
