Removing eslint related packages

Removing Unwanted Packages

Remove the eslint related packages from the application using the following command.

npm remove eslint eslint-config-react-app eslint-plugin-flowtype eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react

Upgrading Packages

React Script packages need to be upgraded to the latest version using the following command.

npm upgrade react-scripts --latest

Installing Packages

Need to install latest version of TypeScript and related definition files with the following command.

npm install typscript@latest @types/node @types/react @types/react-dom @types/react-router @types/reactstrap @types/react-router-dom --save-dev

Renaming the file extension

Once above steps are completed, rename the script file extension from “.js” to “.tsx” under “<project_root_folder>/ClientApp/Src/”.


Now, build and run the application as usual using the Visual Studio IDE.
