How to add additional request body values to Apollo GraphQL request? - reactjs

Question

I'm using Apollo with the Scaphold.io service and for writing blobs to that service I need to be able to add additional options to the request body.
The full Scaphold example can be found here: https://scaphold.io/docs/#uploading-files
But it does something like this:
form.append("variables", JSON.stringify({
"input": {
"name": "Mark Zuck Profile Picture",
"userId": "VXNlcjoxMA==",
"blobFieldName": "myBlobField"
}
}));
// The file's key matches the value of the field `blobFieldName` in the variables
form.append("myBlobField", fs.createReadStream('./mark-zuckerberg.jpg'));
fetch("https://us-west-2.api.scaphold.io/graphql/scaphold-graphql", {
method: 'POST',
body: form
}).then(function(res) {
return res.text();
}).then(function(body) {
console.log(body);
});
Where it adds a blobField to the request body.
Based on this, I need to pass into the variables a blobFieldName property, and then add to the request body the value passed to that property with the blob. However, using Apollo I can't add to the request body. I tried the following, but it's absent from the request body when I check in the network inspector:
export const withCreateCoverPhoto = graphql(CreateCoverPhoto, {
props: ({mutate}) => ({
createCoverPhoto: (name, file) => mutate({
variables: {
input: {
blobFieldName: name,
},
},
[name]: file
}),
}),
});
Please advise.

Thanks for the question. Currently the best way to upload files is by [appending it to FormData and sending it up to the server using fetch] (https://medium.com/#danielbuechele/file-uploads-with-graphql-and-apollo-5502bbf3941e). Basically, you won't be able to have caching here for the file itself, but this is the best way to handle uploading files on Scaphold using a multipart request.
