Hi there,

I am just following up on some of the old unanswered questions on the site.

To handle file uploads in a GraphQL application, you will need to use a combination of a frontend library (such as React) and a server-side technology (such as Node.js) to handle the file uploads.

Here are the general steps for building a fullstack app that can handle file uploads in GraphQL:

  • On the frontend, use a library like react-dropzone to create a user interface for selecting and uploading files. This will allow the user to select files from their device and upload them to your server.

  • Define a GraphQL mutation on the backend that accepts a file as an input argument. This mutation will be responsible for handling the file upload and storing it on the server.

  • In the frontend, use the GraphQL client (such as Apollo Client) to send the file(s) selected by the user to the backend via the defined mutation.

  • On the backend, handle the file upload in the mutation resolver. This involves storing the file on the server and returning a response to the frontend indicating whether the upload was successful.

  • In the frontend, handle the response from the backend and update the user interface to reflect the status of the file upload.

Overall, building a fullstack app that can handle file uploads in GraphQL involves defining a GraphQL mutation on the backend and using a frontend library to handle the file selection and uploading. You can then use the GraphQL client to send the files to the backend for storage and handle the response in the frontend to update the user interface.
