Building a To-Do App with Vue Composition API and Vuex 4 Typescript

How to Build a To-Do App Using Vue Composition API and Vuex 4 with Typescript

Vue Composition API and Vuex 4 can be used together to create powerful, robust and scalable to-do applications. By using the Composition API for logic and Vuex for state management, you can develop your application with the added benefits of TypeScript for type safety and code organization.

1) Setting up your Development Environment

Before you start developing your application, you’ll need to set up your development environment. This includes installing the necessary dependencies, such as Vue, Vuex, and TypeScript. Once these packages are installed, you’ll also need to make sure your project is configured to use these packages, by setting up the webpack configuration and tsconfig files.

2) Writing the Application Code

Once your development environment is set up, you’re ready to start writing the code for your to-do application. You’ll need to define the data model for your to-do list, as well as the components and view models necessary for the application to function. You’ll also need to write the logic for creating, editing, and removing tasks.

For this application, you’ll be writing your logic in the Composition API, which allows you to create functions that can be reused across multiple components. To make this logic more organized and easier to maintain, you can use TypeScript to create types and interfaces for the data models used in the application.

3) Setting up Vuex

Once you’ve written the application code, you’ll need to set up Vuex to handle the state of your application. In Vuex, you’ll need to create two store modules, one for tasks and another for users. You’ll need to write the logic for creating, editing and removing tasks, as well as authentication logic for users. Again, TypeScript can be used to create types and interfaces for the data models and actions in Vuex.

4) Testing the Application

Before launching your application, it’s important to test it to ensure it works as intended. You can use automated tests like Jest or Cypress to run unit and E2E tests on your application. You can also use manual testing to ensure the functionality of your application is working correctly.

5) Launching the Application

Once your application has been tested and all the bugs have been fixed, you’re ready to launch it. Depending on where you’re hosting your application, you may need to package it in a certain way or configure your web server. Once your application has been deployed, you can share it with the world and start collecting feedback.

By following these steps, you should be able to build a powerful, scalable, and robust to-do application using Vue Composition API and Vuex 4 with TypeScript.
