Samples for supported Server Frameworks

This library can be used in combination with several different server frameworks. You can find small code samples for each supported framework below.

Express

const app = require('express')()
const log = require('cf-nodejs-logging-support')

// Configure logger for working with Express framework
log.setFramework(log.Framework.Express)

// Add the logger middleware to write access logs
app.use(log.logNetwork)

// Handle '/' path
app.get("/", (req, res) => {
    // Write a log message bound to request context
    req.logger.info(`Sending a greeting`)
    res.send("Hello Express")
})

// Listen on specified port
const listener = app.listen(3000, () => {
  // Formatted log message
  log.info("Server is listening on port %d", listener.address().port)
})

Connect

const app = require('connect')()
const http = require('http')
const log = require('cf-nodejs-logging-support')

// Configure logger for working with Connect framework
log.setFramework(log.Framework.Connect)

// Add the logger middleware to write access logs
app.use(log.logNetwork)

// Handle '/' path
app.use("/", (req, res) => {
    // Write a log message bound to request context
    req.logger.info(`Sending a greeting`)
    res.end("Hello Connect")
})

// Listen on specified port
const server = http.createServer(app).listen(3000, () => {
    // Formatted log message
    log.info("Server is listening on port %d", server.address().port)
})

Restify

const restify = require('restify')
const log = require('cf-nodejs-logging-support')
const app = restify.createServer()

// Configure logger for working with Restify framework
log.setFramework(log.Framework.Restify)

// Add the logger middleware to write access logs
app.use(log.logNetwork)

// Handle '/' path
app.get("/", (req, res, next) => {
    // Write a log message bound to request context
    req.logger.info(`Sending a greeting`)
    res.send("Hello Restify")
    next()
})

// Listen on specified port
app.listen(3000, () => {
  // Formatted log message
  log.info("Server is listening on port %d", app.address().port)
})

Fastify

const log = require('cf-nodejs-logging-support')
const app = require('fastify')()

// Configure logger for working with Fastify framework
log.setFramework(log.Framework.Fastify)

// Add the logger middleware to write access logs
app.addHook("onRequest", log.logNetwork)

// Handle '/' path
app.get("/", (request, reply) => {
    // Write a log message bound to request context
    request.logger.info(`Sending a greeting`)
    reply.send("Hello Fastify")
})

// Listen on specified port
app.listen({ port: 3000 }, (err, address) => {
    if (err) {
        // Formatted error message
        log.error("Failed to run server", err.message)
        process.exit(1)
    }
    // Formatted log message
    log.info(`Server is listening on ${address}`)
})

Node.js HTTP

const log = require('cf-nodejs-logging-support')
const http = require('http')

// Configure logger for working with Node.js http framework
log.setFramework(log.Framework.NodeJsHttp)

const server = http.createServer((req, res) => {
    // Call logger middleware to write access logs
    log.logNetwork(req, res)

    // Write a log message bound to request context
    req.logger.info(`Sending a greeting`)
    res.send("Hello Node.js HTTP")
})

// Listen on specified port
server.listen(3000, () => {
    // Formatted log message
    log.info("Server is listening on port %d", server.address().port)
})
