The Express example

A whole shop on Express, in the package examples/express: sign in as Ann (support), Ben (a customer) or Cara (the warehouse), each in a browser of their own, and try everything this guide covers.

On the page	What makes it
The order of Ben follows as Ann moves it on, and Ben alone gets a notice	the order:{id} room, sent to by POST /orders/:id/status with except, and toUser (sending)
The chat of Ann and Ben, with typing, reactions and read ticks	<wordplus-chat> on the chat:{a}:{b} room, which lets pages send them. The server keeps the conversation from the webhook and gives it back from GET /chat/messages (keeping the conversation). The name and picture of the other side above it from the directory
Who is in the shop, with a call button for each	<wordplus-online> on the shop presence room, the name and role of each member
The daily meeting	<wordplus-room>, a group call
The order timeline, and what the cloud carried of it	the order room history. GET /orders/:id/wire seals the update as the server sends it, with the room key (encryption)
How many are looking at the mugs	the product:{id} room, public and counted
The webhooks the server got	realtime.on('*'), which sends each on to the shop webhooks room (webhooks)

Try it online at express.docs.wordplus.cloud: this example as a demo, where every visitor gets a shop of their own for a day, and its links open Ben and Cara in windows of their own. Its calls end after 10 minutes and its meetings after 15 (limits in the demo part, which the page keeps to).

Run it

cd examples/express
cp .env.example .env       # the key and secret of your app, with http://localhost:3000 among its addresses, and a local key
npm install                # copies the worker, the room client and the components into public/, and bundles the page
npm start                  # http://localhost:3000

Open it in two browsers (or a private window), sign in as Ann in one and Ben in the other, and move the order on, chat, and call.

Its files

File
server.mjs	the rooms and calls it declares, sign-in with express-session, the order routes, the webhooks, and the pages
demo.mjs	the demo part alone (WORDPLUS_DEMO=1): a shop for each visitor, numbered, its window links, and the frame around the page
shop/shop.js	the page: connect(), the order, the product, the chat, who is in the shop, the webhooks, the meeting and the call screen, in plain DOM. The same file runs the shop in every example
shop/shop.css, shop/avatars/, shop/products/	its look
public/	shop.js bundled by esbuild, and the four files wordplus-realtime copy puts there

The server renders two JSON blocks into the page: its config() for the signed-in user, and the shop data with its routes and room names. The same page runs the shop in the example of every guide in these docs, whatever the server speaks.

It is the server of the mobile example apps too: they sign in with POST /api/token, send the token as Authorization, and a Capacitor app address gets CORS.
