I've recently created a template where you can host games in Express.js with the help of Socket.io.

---

These are all the pages the template has:

• /: has a link to the join game page and the host game page

• /host: generates a game id and creates a game in which others can play the game. The host can decide when to start the game and this triggers a change in Socket.io which changes. the content on the player's screens

• /join contains a form in which you have to enter your game id

• /join (POST): redirects you to /join/[game_id]

• /join/[game_id]: renders a page where you enter your nickname for the game

• /join/[game_id (POST): the user's game id and nickname gets saved to the session and then they get redirected to /play

• /play: the play screen is rendered, and the screen is updated whenever a new socket event is triggered
