ApolloUploadServer

Middleware which allows you to upload files using graphql-ruby, apollo-upload-client and Ruby on Rails.

Note: this implementation uses v2 of the GraphQL multipart request spec, so you should use apollo-upload-client library >= v7.0.0-alpha.3. If you need support for v1 of the GraphQL multipart request spec, you must use version 1.0.0 of this gem.

Installation

Add this line to your application's Gemfile:

gem 'apollo_upload_server', '2.1.0'

And then execute:

$ bundle

Or install it yourself as:

$ gem install apollo_upload_server

Middleware will be used automatically.

Gem adds custom Upload type to your GraphQL types. Use ApolloUploadServer::Upload type for your file as input field:

  input_field :file, ApolloUploadServer::Upload

That's all folks!

Configuration

The following configuration options are supported:

Strict Mode

This can be set on ApolloUploadServer::Middleware:

ApolloUploadServer::Middleware.strict_mode = true

Doing so ensures that all mapped array values are present in the input. If this is set to true, then for following request:

{
  "operations": {
    "query": "mutation { ... }",
    "operationName": "SomeOperation",
    "variables": {
      "input": { "id": "123", "avatars": [null, null] }
    }
  }
}

A mapping for variables.input.avatars.0 or variables.input.avatars.1, will work, but one for variables.input.avatars.100 will not, and will raise an error.

In strict mode, passing empty destination arrays will always fail.
