Trying to bring a vanilla JavaScript function into a TypeScript file within a React Native app has presented some challenges.
The import process goes smoothly when working with JS, but switching to TS triggers the error message:
Cannot use namespace 'PrimaryButton' as a typeThe desired javascript function is located in a node module that exports its function in this format in index.js:
export {default as PrimaryButton} from './src/components/PrimaryButton.js';This node module goes by the name of component-library, owned by the company. It's important to note that it only contains plain JavaScript without any types.
To prevent TS errors on import, a custom.d.ts file has been added to the RN app where component-library is declared as a module:
declare module 'component-library';Despite these efforts, attempting to import the PrimaryButton function leads to the same error:
Cannot use namespace 'PrimaryButton' as a typeIf you're faced with a similar issue and wondering about the best way to successfully import the PrimaryButton function without encountering errors, feel free to ask for help. Navigating TypeScript can be confusing, especially for newcomers.
