Vue & TypeScript: Up and Running

Vue & TypeScript: Up and Running

Daniel Rosenwasser

Daniel is a Program Manager at Microsoft working on the TypeScript language and compiler. TypeScript is JavaScript plus types, specifically static types. In JavaScript all your values already have types, though you may not specify them. Specifying static types helps you recognize bugs and undesirable behavior in your code. Using TypeScript with a tool like VSCode also gets you a ton additional features to help you write less buggy code.

If I want to try TypeScript, in any JavaScript file I can add // @ts-check to see if it identifies problems with my code. I can also start specifying types in JSdoc.

To start seeing the benefit, Daniel showed the following code snippet, and how TypeScript helps you find the error before runtime.

TypeScript is now a part of the new 3.X version of the Vue CLI, making it super simple to bake into your next project. Vetur, created by Pine Wu, is an extension which gives you Vue Tooling for VSCode. To use TypeScript in your Vue files the syntax is easy:

What all is necessary to use TypeScript in your Vue app with .vue files?

  • Use --strict TypeScript settings
  • Use Vetur for editing .vue files
  • Use Vue.extend with the object API
  • Annotate computed methods

The best way to get started with TypeScript in your project is to just add it from the new version of the Vue CLI:
