go-graphqlupload

A file upload middleware for gophers. It enables file upload operations to be done in Go using apollo-upload-client and graph-gophers/graphql-go packages.

Usage

Add the line below to the list of imports

github.com/smithaitufe/go-graphqlupload

Pass the graphql endpoint handler to the graphqlupload.Handler middleware function. Eg.

http.Handler("/graphql", graphqlupload.Handler(relay.Handler...))

In your input struct declaration, simply use the graphqlupload.GraphQLUpload type as datatype against the file input variable.

Eg.

type contactInput struct {
    photo graphqlupload.GraphQLUpload
}

In the schema definition, add the following scalar Upload and you are good to go.

The graphqlupload.GraphQLUpload has two methods

CreateReadStream returns a reader to the upload file(s) WriteFile accepts a name string that indicates where the file should be saved into

In the example folder, there is a working sample.

Thanks.

I hope to improve on it in the coming days
