Alibaba unified front-end form solution
📱🚀 🧩 Cross Device & High Performance Normal Form/Dynamic(JSON Schema) Form/Form Builder -- Support React/React Native/Vue 2/Vue 3.
In React, the whole tree rendering performance problem of the form is very obvious in the controlled mode. Especially for the scene of data linkage, it is easy to cause the page to be stuck. To solve this problem, we have distributed the management of the state of each form field, which significantly improves the performance of the form operations. At the same time, we deeply integrate the JSON Schema protocol to help you solve the problem of back-end driven form rendering quickly.
