krazzarkov/GraphQL-Post-System

Submission for GraphQL Final

Simple GraphQL project which replicates Reddit style posts. Created for my GraphQL class in BCIT.

RUNNING THE SERVER

node index.js

QUERIES

GET POST BY TOPIC

query {
  getPostByTopic(topic: "School"){
    topic
    id
  }
}

GET POST BY ID

query {
  getPostByID(id: "bsh7v9"){
    id
    topic
    comments
  }
}

MUTATIONS

CREATE POST

mutation {
  createPost(created_by: "Kraz", topic: "School", id:"" body: "TEST123", comments: []) {
    created_by
    topic
    id
    body
    comments
  }
}

CREATE COMMENT (BE SURE TO PASTE THE ID GENERATED FROM createPost INTO THE "idpost" FIELD TO ATTACH A COMMENT TO A POST)

mutation {
  createComment(user: "Krazzers", msg: "123", id: "", response: [], idpost: "") {
    user
    msg
    id
    idpost
  }
}

CREATE RESPONSE (BE SURE TO PASTE THE ID GENERATED FROM createComment INTO THE "idcomment" FIELD TO ATTACH A RESPONSE TO A COMMENT)

mutation {
  createResponse (idcomment: "", msg: "123123123123123123") {
    msg
  }
}

SUBSCRIPTION

Subscribe to a post when you create it (replicates reddit system where post author gets automatically subscribed to their own posts)

After the subscription is listening, create a new post and go back to the subscription tab on apollo client to see the results.

subscription {
  newPost {
    id
    topic
    created_by
    body
    comments
  }
}

VIEWING ATTACHED COMMENTS TO POST

After creating a post, creating a comment that attaches to a post, and creating a response that attaches to the comment you can view the result by going back and running the getPostByID query for the speicifc post ID which has the comments and reply already attached to it.

For example: I create a post with ID "123". I then create a comment with ID "999" which attaches to post id "123".

To view the comments all I would have to go is run the getPostByID query for post ID "123" and I would get the following results:

"data": {
    "getPostByID": [
      {
        "id": "123",
        "topic": "School",
        "comments": [
          "Hello"
        ]
      }
    ]
  }
}
