Simplest router possible

routes-router

Simplest request handler possible

DEPRECATED Use http-hash-router instead

var Router = require("routes-router")
var http = require("http")
 
var router = Router()
 
http.createServer(router)
 
router.addRoute("/foo", function (reqres) {
    res.end("hello!")
})
 
router.addRoute("/bars/:barName", function (reqresopts) {
    res.end("you request bars " + opts.params.barName)
})
 
router.addRoute("/foos/:fooName", function (reqresoptscb) {
    db.get(opts.params.fooName, function (errvalue) {
        if (err) return cb(err)
 
        res.end(JSON.stringify(value))
    })
})
 
router.addRoute("/baz/:things", {
    GETfunction (reqres) {
        res.end("I will give you your thing")
    },
    POSTfunction (reqres) {
        res.end("got your things")
    }
})

You can use a router to do central error handling

var Router = require("routes-router")
var sendError = require("send-data/error")
var uuid = require("uuid")
 
var router = Router({
  errorHandlerfunction (reqreserr) {
    err.id = uuid()
 
    // log it somewhere 
    logError(req, res, err)
 
    // if req is json 
    if (isJson(req)) {
      sendError(req, res, err)
    } else {
      // render HTML 500 page 
      renderErrorPage(req, res, err)
    }
  },
  teardownfunction (reqreserr) {
    // an unexcepted exception occured 
    // process is in corrupted state 
    // you have to shut it down 
    // see node domains docs 
  },
  notFoundfunction (reqres) {
    // render a custom 404 page 
    renderNotfoundPage(req, res)
  }
})

Since a Router just returns a function (req, res) {} you can add routers to a router

Here we can just embed a Router instance in another router instance. A child router will use the parent router's callback so all error handling is managed in the parent, not the child.

This means you can define your error handling in your parent and all children will re-use that error handling logic.

Note that we use the .prefix() instead of .addRoute() method to add child routers. The .prefix() ensures that both /user, /user/ and /user/*? goes to the child router.

var Router = require("routes-router")
 
var app = Router({
  errorHandlerfunction (reqres) {
    res.statusCode = 500
    res.end("no u")
  },
  notFoundfunction (reqres) {
    res.statusCode = 404
    res.end("oh noes")
  }
})
 
var users = Router()
var posts = Router()
 
app.prefix("/user", users)
app.prefix("/post", posts)
 
users.addRoute("/", function (reqres) {
  res.end("all users")
})
users.addRoute("/:id", function (reqresopts) {
  res.end("user " + opts.params.id)
})
 
posts.addRoute("/", function (reqres) {
  res.end("all posts")
})
posts.addRoute("/:id", function (reqresopts) {
  res.end("post " + opts.params.id)
})

npm install routes-router
