Approach to Create a Task Scheduling App

• Create – A new task can be added.
• Update – A task can be updated when provided with an Id of the task
• Delete – A task can be deleted when provided with an Id of the task
• Get One Task – A task can be fetched when provided with an Id of the task
• Get All Tasks – All tasks created can be fetched.
• Import the necessary files. Initialize the express app and port to which the local server listens to.
• Set up a middleware using body-parser of express to parse JSON requests.
• Initialize a tasks array that is going to store all the tasks created by a user.
• Write the logic to push the new task created to the task array. This listens to route “/task” using a POST method.
• Write the logic to edit the task by using its id as reference. This listens to route “/task/:id” using a PUT method.
• Write the logic to fetch a single task using its id as reference. This listens to route “/task/:id” using a GET method.
• Write the logic to delete a task using id from the task array. This listens to route “/task/:id” using a DELETE method.

Task Scheduling app is an app that can be used to create, update, delete, and view all the tasks created. It is implemented using NodeJS and ExpressJS. The scheduler allows users to add tasks in the cache of the current session, once the app is reloaded the data gets deleted. This can be scaled using databases like MongoDB and authentication and validation can be added as well.

In this article, we view a simple implementation of a popular example that allows readers to learn how to set up a backend server and create custom APIs using Node and Express.
