Passport.js无状态

Question

I'm using Passport.js local strategies to handle auth in my app. I'm also using Nodemon to automatically refresh the server whenever I make changes.

Problem is whenever I make changes I have to login again to the application. For now this is just development but the same concept would apply to multiple servers handling the requests (ex. EC2 load balancer). So my question is, how can I make Passport.js stateless while still preserving the state of the user?

Seems like there has to be a way to preserve the state across servers and/or restarts of the server.

You have two options:

1. Use a persistent session store eg MongoDB , Redis , or PostgreSQL
2. Do not use sessions at all, use JSON Web Tokens aka JWT instead.

First option requires less setup if you already have a shared database, just instantiate the store and pass it to you app, eg:

const session = require('express-session');
const MongoStore = require('connect-mongo')(session);

app.use(session({
    secret: 'foo',
    store: new MongoStore(options)
}));

The second option requires a different Passport strategy like passport-jwt or maybe ditching Passport completely and using jsonwebtoken directly in a custom middleware.
