I am trying to implement hooks into a React (^16.6.0) application using TypeScript
import * as React, {useState} from 'react';
Any idea what is the right syntax for this import?

import
supports a limited set of syntax variations.
It can be:
import React, {useState} from 'react';
The downside is that entire library is imported, because React
is default export and cannot be tree-shaken. Since the presence of React
import is needed to use JSX syntax, a more efficient way is:
import * as React from 'react';
import {useState} from 'react';
Hooks were introduced in pre-release React 16.7. react
version constraint should be ^16.7.0-alpha.0
, @types/react
should be ^16.7.0
.
Sorry still not working it gives me the following 'Module '"C:/web-client-ts/node_modules/@types/react/index"' has no exported member 'useState'.'
