Quickly create simple JSON API services.

appa

Install

Make sure you've got node installed, then make appa a project dependency:

npm install --save appa

Usage

var http = require('http')
var app = require('appa')()
var send = require('appa/send')
var log = app.log

app.on('/', function (req, res, context) {
  send({ message: 'oh hey friends' }).pipe(res)
})

http.createServer(app).listen(3000, function () {
  log.info('server started at http://127.0.0.1:3000')
})

Error handling

Any uncaught errors that occur in a request handler will be caught and a 500 Internal server error response will be sent.

Send error responses using the appa/error module:

var error = require('appa/error')

module.exports = function (req, res, ctx) {
  return error(404, 'Not found').pipe(res)
}

Sending an error response does not automatically log the error, so to add that you can do something like:

var error = require('appa/error')
var log = require('appa/log')()

module.exports = function (req, res, ctx) {
  log.error(req.method, '500', errorStack)
  return error(500, 'Internal server error').pipe(res)
}

Logging

appa uses pino for logging. Pass options to pino with options.log: appa({ log: pinoOptions }).

See example pino usage and all pino options.

Or disable logging completely by setting options.log to false: appa({ log: false }).
