I am currently working on an application with the current tech stack:

Backend:

• Mongoose




• Express




• Apollo




• GraphQL

Frontend:

• Vuejs




• Apollo




• GraphQL

I have succeeded in uploading files to the server using GraphQL, what I am stuck with is how to implement the 'download' feature. With a normal RESTApi endpoint I can use res.download(filePath) and it works. How do I do this with GraphQL since I don't want to use REST.

Or is there any other standard to go by in this scenario?

Thanks!

GraphQL uses JSON format, which represents as text format, not as binary.

If you don't want download files with REST, then you should:

1. Encode your file content into base64 string on BE. Related question
   


2. Send this string as part of query response.


3. Save encoded base64 string as a file on FE. Related question
   

But right architecture design is add a file link in the GraphQL response and use browser for downloading/rendering the file.
