Package description
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.
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' };This package allows Babel to transform JSON string literals into actual JSON objects. It is similar to @babel/plugin-syntax-import-assertions in that it deals with JSON within the context of JavaScript modules, but it focuses on the transformation of JSON strings rather than the import assertions syntax.
This plugin enables the importing of JSON files as modules in Babel-processed code. It is similar to @babel/plugin-syntax-import-assertions in that it deals with JSON imports, but it automatically converts JSON imports into JavaScript objects without requiring an assertion.
