I am working on a Next.Js-TypeScript project. Everything was fine. Suddenly I get a VS Code warning that I have to write import React from “react” in the .tsx files where I have used Fragment (<></>) of React. But everything was fine until yesterday. I suddenly saw this situation today. Then, I searched the internet and found that the “tsconfig.json” file contains (“jsx”:”preserve”) by default, but if I change it to (“jsx”:”react-jsx”) all the problems are solved. . But there is another problem here. When I start localhost or restart, immediately a message comes in the terminal, that We detected TypeScript in your project and reconfigured your tsconfig.json file for you. Strict-mode is set to false by default. The following mandatory changes were made to your tsconfig.json: - jsx was set to preserve (next.js implements its own optimized jsx transform). After that, the tsconfig.json file is reset as before.
