const redis = require("redis");
const session = require("express-session");
const RedisStore = require("connect-redis")(session);

const REDIS_HOST = process.env.REDIS_HOST || "localhost"
const REDIS_PORT = process.env.REDIS_PORT || 6379

let redisClient = redis.createClient({
  host: REDIS_HOST,
  port: REDIS_PORT
});

module.exports = session({
  store: new RedisStore({ client: redisClient }),
  secret: "super-secret-key", // TBD: grab from env
  resave: false,
  saveUninitialized: false,
  cookie: {
    maxAge: 1000 * 60 * 60 * 24,
    secure: false // require HTTPS in production
  }
