Image/file upload mutation example? about apollo HOT 21 CLOSED

but how do you exactly do it in vue-apollo? there is no documentation found in the apollo.vuejs.org .

from apollo.

https://github.com/wolfiton/vue-upload helped me out a lot

I found for Apollo 2+ there is plugin that can allow upload files with GraphQL
Client: https://github.com/jaydenseric/apollo-upload-client
Server: https://github.com/jaydenseric/apollo-upload-server

from apollo.

here is the example of how I call my mutation:

await this.$apollo.mutate({
    mutation: require('@/app/graphql/mutations/CreateProduct.gql'),
    variables: {
        name: item.name,
        productImage: item.upload,
        units: item.units,
        price: item.price,
        category: item.category.id
    },
    context: {
        hasUpload: true
    }
})

when I console.log(item.upload) it outputs a File object.

here is the example of my mutation:

mutation(
    $name: String!
    $units: Int!
    $productImage: Upload!
    $price: Float!
    $category: ID!
) {
    createProduct(input: {
        name: $name
        units: $units
        productImage: $productImage
        price: $price
        category: { connect: $category }
    }) {
        id
        category {
            name
        }
    }
}

from apollo.

yarn add @apollo/client apollo-upload-client
in your vue-apollo.js file
import {createUploadLink} from 'apollo-upload-client'
then replace http link with createUploadLink({ uri: 'your uri'}),

This worked for me.

from apollo.

I found something but i think its outdated: https://medium.com/@danielbuechele/file-uploads-with-graphql-and-apollo-5502bbf3941e#.qpca4mzfd

from apollo.

I have same problem. Example will help a lot.
@Samuell1 did you found something?

from apollo.

@dsdjolence I using other endpoint to only upload files.

from apollo.

@Samuell1 did you get this work with vue-apollo and apollo-upload-client? I currently try but the issue is that the variables upload array is always NULL instead of a File object. Would be great to see a working example with vue-apollo

from apollo.

nevermind just found the solution in the react examples.

from apollo.

@dohomi
same problem for me. "the variables upload array is always NULL instead of a File object. "

did you find the solution for vue-apollo or nuxt-community/apollo-module?

from apollo.

@razorabhu1995 the NULL client side debug is happening because the server already took over to process the data upload. As long you see the right mutation according to the apollo-upload-client it should work finde. apollo-module let you use file-upload out of the box (make sure you use the most recent version of all the modules - maybe remove node_modules and reinstall to make 100% sure that all packages are up-to-date)

from apollo.

Hey @dohomi I'm still getting NULL when I try to upload a file.
This is my vue-apollo.js config

import Vue from 'vue'
import VueApollo from 'vue-apollo'
import { createApolloClient, restartWebsockets } from 'vue-cli-plugin-apollo/graphql-client'
import { createUploadLink } from 'apollo-upload-client'


// Install the vue plugin
Vue.use(VueApollo)

// Name of the localStorage item
const AUTH_TOKEN = 'auth_token'

// Http endpoint
const httpEndpoint = process.env.VUE_APP_GRAPHQL_HTTP
export const filesRoot = process.env.VUE_APP_FILES_ROOT || httpEndpoint.substr(0, httpEndpoint.indexOf('/graphql'))


Vue.prototype.$filesRoot = filesRoot

// Config
const defaultOptions = {
  // You can use `https` for secure connection (recommended in production)
  httpEndpoint,
  // You can use `wss` for secure connection (recommended in production)
  // Use `null` to disable subscriptions
  wsEndpoint: process.env.VUE_APP_GRAPHQL_WS || null,
  // LocalStorage token
  tokenName: AUTH_TOKEN,
  // Enable Automatic Query persisting with Apollo Engine
  persisting: false,
  // Use websockets for everything (no HTTP)
  // You need to pass a `wsEndpoint` for this to work
  websocketsOnly: false,
  // Is being rendered on the server?
  ssr: false,

  // Override default apollo link
  // note: don't override httpLink here, specify httpLink options in the
  // httpLinkOptions property of defaultOptions.
  // link: myLink
  defaultHttpLink: false,
  httpLinkOptions : {
      httpLink : createUploadLink({
      uri: httpEndpoint,
      })
  },

  // Override default cache
  // cache: myCache

  // Override the way the Authorization header is set
   getAuth: tokenName => {
     // get the authentication token from local storage if it exists
    const token = Vue.cookie.get(tokenName) ? 'JWT ' + Vue.cookie.get(tokenName) : null
    // return the headers to the context so httpLink can read them
    return  token || ''
   },

  // Additional ApolloClient options
  // apollo: { ... }

  // Client local data (see apollo-link-state)
  // clientState: { resolvers: { ... }, defaults: { ... } }
}
// Create apollo client

export const { apolloClient, wsClient } = createApolloClient({
  ...defaultOptions,
})

apolloClient.wsClient = wsClient


// Create vue apollo provider
export const apolloProvider = new VueApollo({
  defaultClient: apolloClient,
  connectToDevTools: true,
  defaultOptions: {
    $query: {
      // fetchPolicy: 'cache-and-network',
    },
  },
  errorHandler (error) {
    // eslint-disable-next-line no-console
    console.log('%cError', 'background: red; color: white; padding: 2px 4px; border-radius: 3px; font-weight: bold;', error.message)
  },
})
// Call this in the Vue app file
export function createProvider (options = {}) {
 
  return apolloProvider
}

Did anyone get this to work?

apollo-upload-client does not have to be imported and integrated. It is already part of vue-apollo, and already integrated.So no need to do anything.

An example will be great :)

from apollo.

@jongbonga just pass a file parameter to your mutation something like this:

mutation uploadFile($id:String!,$file: Upload!){
    uploadFile(id: $id, file: $file){
      .
      .
      .
    }
}

Hi everyone, I get the following error when I pass file to mutation.

app.js:169321 Error: GraphQL error: Variable "$productImage" got invalid value []; Expected type Upload; Could not get uploaded file, be sure to conform to GraphQL multipart request specification: https://github.com/jaydenseric/graphql-multipart-request-spec Instead got: []

Everything should be working but I can't seem to find any example has anyone of your succeeded in finding one??

from apollo.

Hey @asolopovas, can you put an example of your mutation? because it seems your passing an empty array.

from apollo.

As @alexsedeke mentioned, you don't need to add apollo-upload-client to your packages.
Simply create an ApolloClient and call your mutation with a file (or files) as your variables.

Note that the server you are calling must have configured an Upload integration.

// Cache
const cache = new InMemoryCache();

// Create the apollo client
export const apolloClient = new ApolloClient({
  uri: 'LINK TO YOUR GRAPHQL SERVER', // Replace here
  cache,
});

// Mutation
const UPLOAD_MUTATION = gql`
  mutation UploadFile($file: Upload!) {
    uploadFile(file: $file)
  }
`;

// Call mutation in V4 of VueApollo
const { mutate } = useMutation(UPLOAD_MUTATION);

// Make sure this is a file
mutate({ file });

// Or use the apolloClient
apolloClient.mutate({
  mutation: UPLOAD_MUTATION,
  variables: { file },
});

Hope it helps!

apollo-upload-client does not have to be imported and integrated. It is already part of vue-apollo, and already integrated.So no need to do anything.

are currently (Apollo Vuejs client V4) WRONG. You have to use the apollo-upload-client, for example like this:

const client = new ApolloClient({ 
  link: ApolloLink.from([ 
    // ... 
    new HttpLink({
      uri: '/graphql' 
    }) 
  ])
})

(Source: https://dev.to/marvinrabe/file-upload-with-vue-apollo-client-and-graphql-5emb)

Then you can use the normal mutation including the "Upload" Scalar.
