PhotoShare API

PhotoShare is the main back-end exercise for GraphQL Workshop. In this exercise, students build a GraphQL API for a small photo sharing application.

Changes

Add a file type to the Post Photo Input

scalar DateTime

type Photo {
    id: ID!
    name: String!
    url: String!
    description: String
    category: PhotoCategory!
    postedBy: User!
    created: DateTime!
}

Modify the Resolver to Accept the file

resolvers.js

const { GraphQLScalarType } = require('graphql')

__resolvers.js__
...
module.exports = {
    
    ...
    
    DateTime: new GraphQLScalarType({
        name: 'DateTime',
        description: 'A valid date time value.',
        parseValue: value => new Date(value),
        serialize: value => new Date(value).toISOString(),
        parseLiteral: ast => ast.value
    })

}

Test the Upload (no playground)

• Drop the photos collection
• Delete the photos from the assets folder
• navigate to http://localhost:4000/img/photos

query {
  allPhotos {
    id
    url
    created
  }
}
