TUTORIAL VUE 3 EPISODE 4: COMPOSITION API vs OPTION API

Vue.js 3 has introduced the Composition API, which is an alternative to the Options API for creating and managing components. In this tutorial, we will explore the differences between the two and learn when to use each one.

Option API

The Option API is the traditional way of creating Vue components. It involves defining a data, methods, computed, and watch properties within the options object of a component. This approach works well for small to medium-sized applications, but it can become complex and hard to maintain in larger projects.

Composition API

The Composition API is a new way of organizing and defining component logic. It allows developers to group related code together based on features, rather than forcing them to separate code based on options. This makes it easier to manage and reuse code across multiple components. The Composition API also provides better support for TypeScript and improves code organization and readability.

When to use each one?

While both APIs have their strengths, the Composition API is recommended for larger projects or for teams that are familiar with TypeScript or functional programming. It allows for better organization of code and makes it easier to share logic between components. On the other hand, the Option API is still a good choice for smaller projects or for those who are already familiar with Vue.js and prefer a more familiar approach.

Conclusion

Both the Composition API and Option API have their own set of advantages and disadvantages. It is important to consider the specific requirements of your project and the expertise of your team when deciding which API to use. In the end, the goal is to create components that are easy to understand, maintain, and extend, regardless of the API you choose.
