mongoke

Instantly serve your MongoDb database via graphql

DocsExamples

Features

  • Powerful Queries: Pagination, filtering, relation, relay-style connections built-in and generated in a bunch of seconds
  • Works with existing databases: Point it to an existing MongoDb database to instantly get a ready-to-use GraphQL API
  • Authorization via Jwt: Every collection can be protected based on jwt payload and document fields
  • Horizontally Scalable: The service is completely stateless and can be replicated on demand
  • Apollo Federation: The service can be easily glued with other graphql servers to handle writes and more complicated logic.
  • Resilient Idempotent Configuration: One YAML Configuration as the only source of truth, relations, authorization and types in one file

Quickstart:

Using Docker compose

The fastest way to try Mongoke is via docker-compose.

1. Write the configuration to describe the database schema and relations

The ObjectId scalar is already defined by default, it is converted to string when sent as json

# ./mongoke.yml
schema: |
    type User {
        _id: ObjectId
        username: String
        email: String
    }
    type BlogPost {
        _id: ObjectId
        author_id: ObjectId
        title: String
        content: String
    }

types:
    User:
        collection: users
    BlogPost:
        collection: posts

relations:
    - field: posts
      from: User
      to: BlogPost
      relation_type: to_many
      where:
          author_id: ${{ parent['_id'] }}

2. Run the mongoke image with the above configuration

To start the container mount copy paste the following content in a docker-compose.yml file, then execute docker-compose up.

# docker-compose.yml
version: '3'

services:
    mongoke:
        ports:
            - 4000:80
        image: mongoke/mongoke
        environment:
            DB_URL: mongodb://mongo/db
        volumes:
            - ./mongoke.yml:/conf.yml
    mongo:
        image: mongo

3. Query the generated service via graphql or go to http://localhost:4000/graphiql to open graphiql

{
    User(where: { username: { eq: "Mike" } }) {
        _id
        username
        email
        posts {
            nodes {
                title
            }
        }
    }

    BlogPostNodes(first: 10, after: "Post 1", cursorField: title) {
        nodes {
            title
            content
        }
        pageInfo {
            endCursor
            hasNextPage
        }
    }
}
