The signin method will take user sign-in data from the view component, then use fetch to make a POST call to verify the user with the backend. The response from the server will be returned to the component in a promise, which may contain the JWT if sign-in was successful.
mern-skeleton/client/user/api-auth.js:
const signin = (user) => { return fetch('/auth/signin/', { method: 'POST', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' }, credentials: 'include', body: JSON.stringify(user) }) .then((response) => { return response.json() }).catch((err) => console.log(err))}
