What are the best practices for using Vue CLI with TypeScript?

When using Vue CLI with TypeScript, consider the following best practices: 1. Use the latest version of Vue CLI. 2. Enable TypeScript support during project setup. 3. Utilize Vue's Composition API for better type inference. 4. Keep your TypeScript configuration strict for better type safety. 5. Use type definitions for third-party libraries.

Can you explain the Composition API and its benefits?

The Composition API is a new way to organize and reuse logic in Vue components. It allows you to group related code together, making it easier to manage complex components. Benefits include better type inference, improved code organization, and enhanced reusability.

How can I set up TypeScript in an existing Vue project?

To set up TypeScript in an existing Vue project, you can follow these steps: 1. Install TypeScript and the necessary type definitions. 2. Rename your .js files to .ts or .vue files with <script lang="ts">. 3. Create a tsconfig.json file to configure TypeScript options. 4. Update your Vue components to use TypeScript syntax.

What are some common pitfalls to avoid when using TypeScript with Vue?

Common pitfalls include: 1. Not using type definitions for third-party libraries, which can lead to type errors. 2. Overusing any type, which defeats the purpose of TypeScript. 3. Ignoring strict mode settings, which can result in less type safety. 4. Failing to properly type props and emits in components.
