Example
Here’s a simple example demonstrating how to use the Saksh Task Manager:
`javascript
const SakshTaskController = require('saksh-task-manager');
const mongoose = require('mongoose');
const run = async () => {
try {
// Connect to MongoDB
await mongoose.connect('mongodb://localhost:27017/sakshtask', {
useNewUrlParser: true,
useUnifiedTopology: true,
});
console.log('MongoDB connected');
// Create an instance of SakshTaskController with a user ID
const userId = 'your-user-id-here'; // this can be user email id also
const taskController = new SakshTaskController(userId);
// Create a new task
const newTask = await taskController.sakshCreateTask({ name: 'Sample Task', fileUrl: 'http://example.com/file.pdf' });
console.log('Task Created:', newTask);
// Get all tasks
const tasks = await taskController.sakshGetTasks();
console.log('All Tasks:', tasks);
// Update a task
const updatedTask = await taskController.sakshUpdateTask(newTask._id, { completed: true });
console.log('Task Updated:', updatedTask);
// Delete a task
const deleteMessage = await taskController.sakshDeleteTask(newTask._id);
console.log(deleteMessage);
} catch (error) {
console.error('Error:', error.message);
}
};
run();
