Uncaught syntaxerror: ambiguous indirect export: default

The error “Uncaught SyntaxError: Ambiguous indirect export: default” occurs when using the “export” statement in JavaScript in an unclear or conflicting way.

In JavaScript, the “export” statement is used to declare functions, objects, or values to be exported from a file or module, making them accessible to other modules through the “import” statement. However, this error is thrown when the usage of the “export” statement creates ambiguity or conflicts with other exported items.

To understand this error, let’s consider an example:

      // example.js
      export default function foo() {
        // function implementation
      }
      
      export function bar() {
        // function implementation
      }
      
      // main.js
      import foo from './example.js';
      import { bar } from './example.js';
      
      foo(); // invoking the default export
      bar(); // invoking the named export
    

In the example above, the “example.js” file exports a default function “foo” and a named function “bar”. In the “main.js” file, we are importing both functions and trying to invoke them. However, this will result in the “Uncaught SyntaxError: Ambiguous indirect export: default” error because the default export “foo” conflicts with the named export “bar”.

To fix this error, we have a couple of options:

1. Rename either the default export or the named export to avoid conflicts:

           // example.js
           export default function defaultFoo() { // renaming default export
             // function implementation
           }
           
           export function bar() {
             // function implementation
           }
           
           // main.js
           import defaultFoo from './example.js'; // using the renamed default export
           import { bar } from './example.js';
           
           defaultFoo(); // invoking the default export
           bar(); // invoking the named export
         

2. Use a different import syntax to avoid conflicts:

           // example.js
           export default function foo() {
             // function implementation
           }
           
           export function bar() {
             // function implementation
           }
           
           // main.js
           import * as example from './example.js'; // import all exports as an object
           
           example.default(); // invoking the default export
           example.bar(); // invoking the named export
         

By implementing one of the above fixes, the “Uncaught SyntaxError: Ambiguous indirect export: default” error should be resolved.
