This project is a minimum example of how to manage a login with a session token.

I wanted to create a simple tutorial for some of my colleague to understand the logic. It uses react-hook-form for managing the login form and react-cookie for managing the connection cookie.

I explain with all the details how I build the project and my way of working.

The jsdoc can be generated locally with the following command :

npm run build:docs

Inside the App.js, we get the token using the useToken hook. If the token exist, we let the user going wherever he want excepted login. In case the user want to go to the login page with a valid token, we redirect him to the private dashboard. If the token does not exist, we redirect the user to the login page. The public pages does not check the token at all.

Inside the useToken, we can do 3 things, set the token, get the token and check the token. When the user successfully login, we save his token. The checkToken check that the token exist and check using the backend that this one is good (in this minimal version, I am just checking his value). In case the token has been changed manually, the token is invalid and the user is considered without a token.
