Data models:

• TreeNode: It is the most elementary structure of a tree. It contains the node data and pointers to its children. Here a TreeNode has:

  • data: title, body
  • children: [array of referrences to child nodes]
  • parent: referrence to the parent node.
  • depth: depth of the node in the story tree
  • version: horizontal versioning at same depth
  • storyId: referrence to the story

• Story: This is a presentational structure and is basically a whole tree. Eventually it contains a head-node only. Head-node then has its children and they have their children and so on, forming a story. Structure of story model is as:

  • storyTitle: the story title
  • headNode: referrence to the head-node of the story.

• User: To be decided.

Routes

Following routes can be used with https://node-contribute.herokuapp.com/ to perform various operations.

• Create a story: POST: /story/create {body:{Story Body},storyTitle:{Story title}} (must be always performed first as node creation requires a parent to be present)
• View a story: GET: /story/{Story id}
• Add a node: POST: /node/add {body:{Node body},parentId:{this node's parent id}}
• View a node: GET: /node/{node id}
• View all stories: GET: /story
• View all nodes: GET: /node
• Update a node: POST: /node/:id/update {newBody:"New Body", nodeId:"id of node"}
