Small volume is introduced

As the most popular framework at present, Vue is widely used in practical development. Vue3.0 was released in September 2020. Based on Vue2, Vue3 introduces typescript to refactor a large amount of code, resulting in some new features and incompatibility changes.

  • Composition Api: Greatly improves the flexibility of code Composition, makes it easy to split functional modules, makes your code more concise and free, global Api changes are also more Tree Shaking friendly support.
  • New reactive solutions: Proxy replaces Object.defineProperty for reactive, implements true data interception, redefines ref and Reactive methods to create reactive variables, and many more advanced uses related to THE JS API.
  • Vite: a new generation of build tools, millisecond level of cold start and hot update time, using modern browsers support ES Modules features, completely omit the packaging step, Esbuild pre-build module is 10~100 times faster than Webpack.
  • Vue3 family bucket: With the upgrade of Vue3, VUE-Router and Vuex are also upgraded to @4 version respectively. The new routing system and data management will also improve the performance of our project.

Follow this small volume, the new feature analysis, to the project of migration and upgrading, from the construction tool to the whole family bucket combat, in all aspects of project development with you to understand the features of Vue3, to help you step by step to upgrade your front-end framework, easy to play Vue3.
