Easily expose your http server's health.
npm install healthpointEasily expose your http server's health.
``js
var http = require('http')
var healthpoint = require('healthpoint')
var hp = healthpoint({
version: require('./package.json').version
}, function (cb) {
// ordinarily you chould check your db connection
// instead we'll just alternate between healthy and fail every 5 seconds
var isOk = Math.round(Date.now() / 5000) % 2
cb(isOk ? null : new Error('Having a bad time...'))
})
http.createServer(function (req, res) {
if (req.url === '/health') return hp(req, res)
res.end('Visit /health for the health check')
}).listen(1337)
console.log('Visit http://localhost:1337/health for the health check')
`
healthpoint() will return an http request handler function. healthpoint() takes up to two optional arguments, properties and check.
Any key/value pairs on properties will be exposed on the health check JSON. This is useful for adding things like your app's version.
check is a function that will be called with a callback. If the callback is called with an error as its argument, the health check JSON will have a 500 statusCode and will display status: 'Error'`.
