How can I set a cookie in react?

Little update. There is a hook available for react-cookie

1) First of all, install the dependency (just for a note)

yarn add react-cookie

or

npm install react-cookie

2) My usage example:

// SignInComponent.js
import { useCookies } from 'react-cookie'

const SignInComponent = () => {

// ...

const [cookies, setCookie] = useCookies(['access_token', 'refresh_token'])

async function onSubmit(values) {
    const response = await getOauthResponse(values);

    let expires = new Date()
    expires.setTime(expires.getTime() + (response.data.expires_in * 1000))
    setCookie('access_token', response.data.access_token, { path: '/',  expires})
    setCookie('refresh_token', response.data.refresh_token, {path: '/', expires})

    // ...
}

// next goes my sign-in form

}

Hope it is helpful.

Suggestions to improve the example above are very appreciated!

I set cookies in React using the react-cookie library, it has options you can pass in options to set expiration time.

An example of its use for your case:

import cookie from "react-cookie";

setCookie() => {
  let d = new Date();
  d.setTime(d.getTime() + (minutes*60*1000));

  cookie.set("onboarded", true, {path: "/", expires: d});
};

Use vanilla js, example

document.cookie = `referral_key=hello;max-age=604800;domain=example.com`

It appears that the functionality previously present in the react-cookie npm package has been moved to universal-cookie. The relevant example from the universal-cookie repository now is:

import Cookies from 'universal-cookie';
const cookies = new Cookies();
cookies.set('myCat', 'Pacman', { path: '/' });
console.log(cookies.get('myCat')); // Pacman
