You will need a runtime to actually use the server. (adapt command to your package manager)

npm install @rjweb/runtime-bun # for bun users

Example Usage

All Utilities and examples for specific classes are available in the Documentation.

This Web Server Library is not for pure beginners. For anything slightly advanced you will need basic knowledge of servers. Same with the documentation, very few is provided directly. You should be able to find everything in TSDoc @example sections of the respective Method.

Basic Server

import { Server } from "rjweb-server"
import { Runtime } from "@rjweb/runtime-node"

const server = new Server(Runtime, {
  port: 8080 // https://server.rjweb.dev/types/ServerOptions
})

server.path('/', (path) => path
  .http('GET', '/', (http) => http
    .onRequest((ctr) => {
      return ctr.print('Hello World!')
    })
  )
)

server.start().then((port) => {
  console.log(`Server started on port ${port}!`)
})
Copy

Serve Side Events

import { Server } from "rjweb-server"
import { Runtime } from "@rjweb/runtime-node"
import { time } from "@rjweb/utils"

const server = new Server(Runtime, {
  port: 8080 // https://server.rjweb.dev/types/ServerOptions
})

server.path('/', (path) => path
  .http('GET', '/timer', (http) => http
    .document({
      parameters: [
        {
          in: 'query',
          name: 'seconds',
          required: false,
          schema: {
            type: 'number'
          }
        }
      ]
    })
    .onRequest((ctr) => {
      ctr.headers.set('content-type', 'text/event-stream')
      ctr.headers.set('x-accel-buffering', 'no')
      ctr.headers.set('cache-control', 'no-cache')
      ctr.headers.set('connection', 'keep-alive')

      let seconds: number | null = null
      const secondsInt = parseInt(ctr.queries.get('seconds', ''))

      if (!isNaN(secondsInt) && secondsInt >= 1) seconds = secondsInt

      ctr.printChunked((print) => new Promise<void>(async(end) => {
        print('retry: 10000\n\n')

        let count = 0
        const interval = setInterval(() => {
          count++

          print(`data: ${count}\n\n`)
          if (seconds && seconds <= count) {
            clearInterval(interval)
            end()
          }
        }, time(1).s())

        ctr.$abort(() => {
          clearInterval(interval)
          end()
        })
      }))
    })
  )
  .http('GET', '/openapi', (http) => http
    .onRequest((ctr) => {
      return ctr.print(server.openAPI('Example Server', '1.0.0', { url: 'http://localhost.8080' }))
    })
  )
)

server.start().then((port) => {
  console.log(`Server started on port ${port}!`)
})
Copy

Websockets

import { Server } from "rjweb-server"
import { Runtime } from "@rjweb/runtime-node"
import { time } from "@rjweb/utils"

const server = new Server(Runtime, {
  port: 8080 // https://server.rjweb.dev/types/ServerOptions
})

server.path('/', (path) => path
  .ws('/echo', (ws) => ws
    .onMessage(async(ctr) => {
      await ctr.print(ctr.messageType(), ctr.rawMessageBytes())
    })
  )
)

server.start().then((port) => {
  console.log(`Server started on port ${port}!`)
})
Copy
