The @babel/plugin-syntax-import-assertions package allows Babel to parse the import assertions syntax, which is a feature that enables developers to make assertions about the kind of content they are importing. This is particularly useful for ensuring that modules being imported are of the expected type, such as JSON, HTML, or other non-JavaScript resources.

What are @babel/plugin-syntax-import-assertions's main functionalities?

Parsing import assertions

This feature allows Babel to understand and parse the import assertions syntax, which is used to assert the type of file being imported. In this code sample, an assertion is made that the imported module 'data.json' is of type 'json'.

import json from './data.json' assert { type: 'json' };
