[Meteor + Apollo] get blob url instead file

[nguyenhose]

hi, I'm try to use this package to upload a file following instruction, but I got a blob url instead file. Here is my code:
in server.js:

 {...}
import graphqlExpressUpload from 'graphql-server-express-upload'
import multer from "multer";

//used your interface package when create apollo server
import { createApolloServer } from 'meteor/apollo';

const WS_PORT =  8083;

const schema = makeExecutableSchema({
  typeDefs:Schema,
  resolvers:resolveFunctions,
});

createApolloServer({
  schema,
},{ graphiql:true});

const httpServer = createServer((request, response) => {
  response.writeHead(404);
  response.end();
});

httpServer.listen(WS_PORT);
const server = new SubscriptionServer({ subscriptionManager }, httpServer);

const app = express();

const storage = multer.diskStorage({
    destination: function (req, file, callback) {
        callback(null, 'uploads');
    },
    filename: function (req, file, callback) {
        console.log(file);
        var filename = file.originalname;
        var fileExtension = filename.split(".")[1];
        callback(null, Date.now() + "." + fileExtension);
    }
});

const upload = multer({
    storage: storage
});

app.use('/graphql',
    upload.array('files'),
    bodyParser.json(),
    graphqlExpressUpload({ endpointURL: '/graphql' }), // after multer and before graphqlExpress
    graphqlExpress((req) => {
        console.log('req', req);
      return {
        schema,
        context: {}
      }
    })
);

app.use('/graphiql', graphiqlExpress({
  endpointURL: '/graphql',
}));

in resolver.js

async uploadProfilePicture(root, { id, files }, context) {

           //the result of files was like [ { preview: 'blob:http://localhost:3000/8d38f565-7846' } ] }

            console.log('uploadProfilePicture', { id, files })

            return uploadProfilePicture(id, files);
        },

in the result I got a blob url like { preview: 'blob:http://localhost:3000/8d38f565-7846' }
Please help.

Hmm ... I'm not sure that I understand what your problem is ... Is file uploaded successfully? Can you view http://localhost:3000/8d38f565-7846? Can you post Request Payload from the upload mutation? What does uploadProfilePicture() return?

[nguyenhose]

function uploadProfilePicture() : Boolean

the problem is I upload a file with attributes

file {
  lastModified: 1478153157000
  lastModifiedDate: Thu Nov 03 2016 13:05:57 GMT+0700 (ICT)
  name: "14590413_698257190343797_6999820439999271573_n.jpg"
  preview: "blob:http://localhost:3000/fca57484-807b-4e3d-9905-ea036689f3f6"
  size: 78435
  type: "image/jpeg"
  webkitRelativePath: ""
}

but only got

{ preview: 'blob:http://localhost:3000/fca57484-807b-4e3d-9905-ea036689f3f6' }

what do you think ?

@nguyenhose I also see the same thing when I use a react component like react-dropzone. How are you selecting the file?

edited
When I use the standard html input type = file it seems to work

[nguyenhose]

@jcampb yes, I am using react-dropzone, too !!! Maybe it's the problem.

[HriBB]

So if I understand correctly, you don't receive any file data on the server? I'm not sure what react-dropzone does, but it might be related to this issue? Only FileList is supported ATM, take a look at this line.

@nguyenhose is this Request Payload or a response from the server?

file {
  lastModified: 1478153157000
  lastModifiedDate: Thu Nov 03 2016 13:05:57 GMT+0700 (ICT)
  name: "14590413_698257190343797_6999820439999271573_n.jpg"
  preview: "blob:http://localhost:3000/fca57484-807b-4e3d-9905-ea036689f3f6"
  size: 78435
  type: "image/jpeg"
  webkitRelativePath: ""
}

This is how my Request Payload looks like

@HriBB any update on this? I know I said I'd help a while back but I've been super busy at work. Are we still only supporting FileList objects? It would be nice if we provided some sort of casting function and presented blobs rather than FileLists

[HriBB]

@thebigredgeek sorry, I am on vacation in Turkey ATM. I come back on March 5th, and we can fix/support this.

@thebigredgeek I have fairly recently published an alternative you might find easier to setup (no Multer setup needed) and a little more flexible: apollo-upload-server. It does not provide files to the resolver as blobs from memory (I did look into that at first), but it does allow you to intuitively work with either a single File, a File array, or a FileList.

I will be actively improving apollo-upload-server and apollo-upload-client for as long as Apollo does not support uploads natively, as I am using both in two fairly large projects.
