Sign-in

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))
}
