Streamlining Task Management: Harnessing Modus Framework and DGraph for Automation

Objective:
Develop an automation system to streamline task management, utilizing The Modus Framework for modular architecture and DGraph for managing relational data in real-time.

---

Features

1. Task Creation
   Automate task assignments based on predefined rules or incoming events.

2. Real-Time Updates
   Use DGraph's graph database to maintain real-time task dependencies and relationships.

3. Notification System
   Notify team members or systems when tasks

1. Initialize Modus Framework Project

Start a new Modus project using the CLI:

bashCopy codenpx modus-cli create my-task-automation
cd my-task-automation
npm install

Create the necessary modules for the task automation system:

bashCopy codemodus-cli generate module tasks
modus-cli generate module notifications
modus-cli generate module analytics

---

2. Set Up DGraph

1. Install DGraph: You can run DGraph locally using Docker:

    bashCopy codedocker run -it -p 8080:8080 -p 9080:9080 -p 8000:8000 dgraph/standalone:latest
   

2. Define the Schema: Create a schema for tasks, dependencies, and users. Use DGraph's Ratel UI or GraphQL API to set it up:

    graphqlCopy codetype Task {
      id: ID!
      title: String!
      description: String
      status: String
      assignedTo: User
      dependencies: [Task]
      createdAt: DateTime
      updatedAt: DateTime
    }
   
    type User {
      id: ID!
      name: String!
      email: String!
    }
   

3. Add Sample Data:

    graphqlCopy codemutation {
      addTask(input: [
        {
          title: "Create Hackathon Proposal",
          description: "Prepare the initial proposal for the Hackathon project.",
          status: "pending",
          assignedTo: { id: "user-1" },
          createdAt: "2024-11-28T12:00:00Z",
          updatedAt: "2024-11-28T12:00:00Z"
        }
      ]) {
        task {
          id
        }
      }
    }

3. Connect Modus Framework to DGraph

Create a service in the tasks module to query and mutate DGraph data:

• Install the required library:

    bashCopy codenpm install dgraph-js grpc
  

• Configure a connection in tasks/service/taskService.ts:

    typescriptCopy codeimport * as dgraph from "dgraph-js";
    import * as grpc from "grpc";
  
    const clientStub = new dgraph.DgraphClientStub(
      "localhost:9080",
      grpc.credentials.createInsecure()
    );
  
    const dgraphClient = new dgraph.DgraphClient(clientStub);
  
    export const getTasks = async () => {
      const query = `
        query allTasks {
          tasks(func: has(title)) {
            id
            title
            status
            assignedTo {
              name
              email
            }
          }
        }
      `;
      const res = await dgraphClient.newTxn().query(query);
      return res.getJson();
    };
  
    export const addTask = async (task) => {
      const txn = dgraphClient.newTxn();
      try {
        const mutation = new dgraph.Mutation();
        mutation.setSetJson(task);
        const req = new dgraph.Request();
        req.addMutations(mutation);
        await txn.mutate(req);
        await txn.commit();
      } finally {
        await txn.discard();
      }
    };

4. Develop Automation Rules

Use Modus services and schedulers for task automation. For example, in tasks/scheduler/taskScheduler.ts:

typescriptCopy codeimport { scheduleJob } from "node-schedule";
import { getTasks } from "../service/taskService";

export const overdueTaskChecker = () => {
  scheduleJob("0 * * * *", async () => {
    const tasks = await getTasks();
    const overdueTasks = tasks.filter(
      (task) => task.status === "pending" && new Date(task.deadline) < new Date()
    );
    overdueTasks.forEach((task) => {
      // Notify users via email or Slack
      console.log(`Task overdue: ${task.title}`);
    });
  });
};

---

5. Create APIs for Frontend

Use Modus controllers to expose REST or GraphQL APIs. In tasks/controller/taskController.ts:

typescriptCopy codeimport { addTask, getTasks } from "../service/taskService";

export const taskController = {
  async list(req, res) {
    const tasks = await getTasks();
    res.json(tasks);
  },

  async create(req, res) {
    const newTask = req.body;
    await addTask(newTask);
    res.status(201).json({ message: "Task added successfully!" });
  },
};

---

6. Deploy the Project

1. Use services like Render, Heroku, or Vercel for deployment.

2. Host the DGraph instance on Dgraph Cloud or AWS EC2 for production use.

3. Add CI/CD pipelines for code quality and testing.

---

Demo Plan

For the d-graph demo:

• Showcase real-time updates in task status via the DGraph API.

• Demonstrate automation using schedulers.

• Present a frontend interface with a dashboard of tasks and analytics.

By combining Modus Framework's modularity with DGraph's efficiency, this project creates a scalable and high-performance solution for task automatio
