Zhunio's library for Node.js

API

var zhunio = require('zhunio')

The zhunio var is an object that contains two properties: Err, and Logger.

zhunio.Err

var Err = zhunio.Err

The Err object contains two HTTP request middleware functions: catch, and handler. The catch middleware function catches any HTTP request error. The handler middleware function handles any HTTP request error.

var express = require('express')
var zhunio = require('zhunio')
app = express()

// Err object
var Err = zhunio.Err

// Error catching, and handling
app.use(Err.catch)
app.use(Err.handler)

zhunio.Logger(path)

var path = require('path')

// Path to logs directory
var web = path.join(__dirname, 'logs')

var Logger = zhunio.Logger(web)

The Logger function receives a path to the directory that will contain the logs. It returns a Logger that contains contains two HTTP request middleware functions: error, and access. The error middleware function logs any HTTP request error. The access middleware funtion logs any HTTP request access.

// Create express app
app = express()

// Err object
var Err = zhunio.Err

// Error logging, catching, and handling
app.use(Logger.error)
app.use(Err.catch)
