simple implementation of a single use "ticket". This module exposes key: value set and get methods. key must be a String, and value can be anything. The get method returns the value then deletes the key:value from the store. This is useful for building 3 party ticket based authentication tools.
npm install redis-ticket
- redis: passed directy to (Node Redis)[https://www.npmjs.com/package/redis]
- prefix: value that is prefixed to all keys, default is 'r-ticket:'. If you don't want a prefix specify the empty string, i.e.
prefix: ''
const RedisTicket = require('redis-ticket');
const ticketStore = new RedisTicket({
// NOTE: for most cases should not have to specify any options
prefix: 'socket-tickets:',
port: 6379
});
// ...
// after authenticating `user`
const key = getUUID(); // function that returns a universally unique ID, e.g. UUID V4
await ticketStore.set(key, {_id: user._id});
// elsewhere..
io.use(function (socket, next) {
// already authenticated
if (socket.user) return next();
var ticket = socket.handshake.query && socket.handshake.query.authticket;
if (ticket) {
const user = await ticketStore.get(ticket);
const userId = user && user._id
// get user from db and attach to socket...
