  • In the above graph there are 2 types of node , "Hidden Node" and "Non Hidden Node" which is connected to another node. The connection is call "edges" .

  • "node" and "edges" data look likes :

let nodes = [
  { id: 1, node_name: "Node-1", is_hiddenable: false, hidden: false },
  { id: 2, node_name: "Node-2", is_hiddenable: false, hidden: false },
  { id: 3, node_name: "Node-3", is_hiddenable: true, hidden: false },
  { id: 4, node_name: "Node-4", is_hiddenable: true, hidden: false },
  { id: 5, node_name: "Node-5", is_hiddenable: true, hidden: false },
  { id: 6, node_name: "Node-6", is_hiddenable: false, hidden: false },
  { id: 7, node_name: "Node-7", is_hiddenable: false, hidden: false },
  { id: 8, node_name: "Node-8", is_hiddenable: true, hidden: false },
  { id: 9, node_name: "Node-9", is_hiddenable: true, hidden: false },
  { id: 10, node_name: "Node-10", is_hiddenable: true, hidden: false },
  { id: 11, node_name: "Node-11", is_hiddenable: false, hidden: false },
  { id: 12, node_name: "Node-12", is_hiddenable: false, hidden: false },
  { id: 13, node_name: "Node-13", is_hiddenable: false, hidden: false },
  { id: 14, node_name: "Node-14", is_hiddenable: true, hidden: false },
  { id: 15, node_name: "Node-15", is_hiddenable: false, hidden: false },
  { id: 16, node_name: "Node-16", is_hiddenable: false, hidden: false },
  { id: 17, node_name: "Node-17", is_hiddenable: true, hidden: false },
  { id: 17, node_name: "Node-18", is_hiddenable: true, hidden: false },
  { id: 17, node_name: "Node-19", is_hiddenable: false, hidden: false },
 ... 
 ...  // can be 'n' number
];


let edges = [
  { from: 1, to: 2, icon: "" },
  { from: 2, to: 3, icon: "-" },
  { from: 3, to: 4, icon: "" },
  { from: 4, to: 5, icon: "" },
  { from: 5, to: 6, icon: "" },
  { from: 2, to: 7, icon: "" },
  { from: 7, to: 8, icon: "-" },
  { from: 8, to: 9, icon: "" },
  { from: 9, to: 10, icon: "" },
  { from: 10, to: 11, icon: "" },
  { from: 2, to: 12, icon: "" },
  { from: 12, to: 16, icon: "" },
  { from: 16, to: 17, icon: "-" },
  { from: 17, to: 18, icon: "" },
  { from: 18, to: 19, icon: "" },
  { from: 12, to: 13, icon: "" },
  { from: 13, to: 14, icon: "-" },
  { from: 14, to: 15, icon: "" },
   ... 
   ...  // can be 'n' number
];
  • Hidden Node can be identify, if "is_hiddenable" is true from node array.
  • Hidden Node can be hide, if "hidden" is true from node array.
  • icon (-/+) can be display, if "icon" is (-/+) from edges array.
  • When click on (-) icon which is in between 'node 7' and 'node 8', The 'node 8 , node 9 and node 10' which are 'is_hiddenable', should be "hidden". And the edges { from: 10, to: 11, icon: "" } should update to { from: 7, to: 11, icon: "" }.like in graph 2

  • When click on (+) icon which is in between 'node 7' and 'node 11', The 'node 8 , node 9 and node 10' which are 'is_hiddenable', should be display. And the edges { from: 7, to: 11, icon: "" } should update to { from: 10, to: 11, icon: "" }.like graph 3

  • "node" and "edges" data for graph2 look likes :

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
