@wll8/express-ws v1.0.5

express-ws

Quickly implement websocket API in express.

There are some issues with HenningM/express-ws, the author has not been active for more than 1 year. So I created this project.

This repository is not intended to be a replacement, but to provide options to solve a problem, you can view the differences here.

It may provide a solution for the following problems:

• https://github.com/HenningM/express-ws/issues/157
• https://github.com/HenningM/express-ws/issues/126
• https://github.com/HenningM/express-ws/issues/52

Features

• Use directly from app.ws
• http and ws of the same route can exist at the same time
• Support dynamic routing
• Support reading params, query parameters
• Support Typescript

how to use

npm i @wll8/express-ws

const express = require(`express`)
const expressWs = require(`@wll8/express-ws`)
const {app, wsRoute} = expressWs(express())

app.ws(`/abc`, (ws, req) => {
  // const {params, query} = req
  ws.send(`abc`)
})
app.get(`/abc`, (req, res) => {
  res.json(`abc`)
})

app.listen(3040)

• For more examples see the file: test.js
• dependencies

  "path-to-regexp": "0.1.7",
  "ws": "7.5.5"
