Hello, World
\")\n\n // \"/foo.txt\"\n $(\"txt\")\n .contentType(\"text/plain\")\n .content(\"Hello, World\")\n\n })\n})\n```\n\nYou can limit a path to a particular HTTP method. Any HTTP method may\nbe used, in addition to the special ``ANY`` method.\n\n```javascript\n.route(function (ANY, GET) {\n GET(\"hello\").content(\"Hello, World!\");\n})\n```\n\nThe common methods are provided as positional arguments, of which you\ncan take as many as you need: ``ANY``, ``GET``, ``PUT``, ``POST``, and\n``DELETE``, in that order.\n\n```javascript\n.route(function (ANY, GET, PUT, POST, DELETE) {\n GET(\"hello\").content(\"Hello, World!\");\n})\n```\n\nAll other valid methods are provided as functions on ``this``.\n\n```javascript\n.route(function () {\n this.OPTIONS(\"hello\").methodNotAllowed();\n})\n```\n\nBut, you'll get proper HTTP responses for free if you use content\nnegotiation.\n\n```javascript\n.route(function ($) {\n $(\"foo\").methods(function ($) {\n var value;\n\n $(\"GET\")\n .json()\n .app(function () {\n return value;\n });\n\n $(\"PUT\")\n .jsonRequest()\n .tap(function (object) {\n value = object;\n })\n .redirect();\n\n })\n})\n```\n\nEach route selector accepts any number of conditions (predicates). If\nthe predicate is a function, the function gets called with ``request``\nand ``response`` and it must return ``true`` for the route to be\nselected.\n\n```javascript\n.route(function ($) {\n $(\"hello\", function (request) {\n return request.headers.host === \"localhost\";\n }).content(\"Hello\");\n})\n```\n\nSo you can profane the HTTP specification if you must:\n\n```javascript\n.route(function ($) {\n $(function (request) {\n return request.method === \"NYANCAT\";\n }).redirect(\"http://nyan.cat/\");\n})\n```\n\nIf no route is selected, the route will continue searching for an app\ndown the chain.\n\n```javascript\n.route(function ($, GET) {\n GET(\"hello\").content(\"Hello, World\")\n})\n.redirectTemporary(\"hello\")\n```\n\nYou can put a cap on routing, which will end a route. If a request\nreaches a route cap with any part of the request URL unprocessed the\nserver will respond with a 404 \"Not Found\".\n\n```javascript\n.cap()\n```\n\n\nNegotiation\n-----------\n\nYou can use chains to limit what HTTP Method and Host you are willing to\nrespond to.\n\n```javascript\n.host(\"localhost\")\n.method(\"GET\")\n```\n\nAnd you can and should use chains to perform content-negotiation. With\nthe ``contentType``, ``language``, ``encoding``, ``charset`` functions,\nrouting will only proceed through the chain if the client is able to\naccept the given parameter. This is what Corbain Dallas would probably\ncall Content Negotiation.\n\n```javascript\n.charset(\"utf-8\")\n.contentType(\"text/html\")\n.language(\"en\")\n.content(\"I wonder.\")\n```\n\nOnce negotiation is complete, the corresponding response headers are\nautomatically populated. So, if you've negotiated to respond in\n``text/html``, the ``Content-Type`` header of the response will be sent\nwith the headers automatically. It is however up to you to ensure that\nyour response content satisfies the negotiated terms. The negotiation\nresults are stored in ``request.terms``.\n\n```javascript\n.charset(\"utf-8\", \"ascii\")\n.app(function (request) {\n assert.ok([\"utf-8\", \"ascii\"].indexOf(request.terms.charset) >= 0);\n})\n```\n\nAlternately, you can bring multiple options to the content negotiation.\n\n```javascript\n.route(function ($, GET) {\n GET(\"foo\").route(function (\".\", function (ext) {\n ext(\"html\").app(html);\n ext(\"text\").app(text);\n ext(\"txt\").app(text);\n })\n .contentTypes(function (type) {\n type(\"text/html\").app(html);\n type(\"text/plain\").app(text);\n })\n})\n```\n\nYou can branch likewise on hosts:\n\n```javascript\n.host(\"localhost:*\", \"127.0.0.1:*\")\n.hosts(function ($) {\n $(\"localhost:*\", \"127.0.0.1:*\")\n .contentType(\"text/plain\")\n .content(\"Hello, local client.\")\n .cap()\n})\n```\n\n- ``hosts``\n- ``methods``\n- ``contentTypes``\n- ``languages``\n- ``charsets``\n- ``encodings``\n\n\nMiddleware\n----------\n\nAnd you can wrap your route in middleware.\n\nLogging middleware shows request and response times and statuses.\n\n```javascript\n.log()\n.log(console.log, stamp(message))\n```\n\nError middleware transforms errors into 500 Server Error pages.\n\n```javascript\n.error()\n```\n\nFavicon middleware handles requests for ``/favicon.ico``.\n\n```javascript\n.favicon()\n.favicon(path)\n```\n\nAnd to avoid carpal tunnel, you can just use sensible defaults for\nmiddleware.\n\n```javascript\n.blah()\n.blah({\n log: console.log,\n stamp: function (message) {return new Date() + \" \"},\n favicon: path,\n debug: true\n})\n```\n\nIn fact, if you're in a real hurry, as in say, on a REPL, you can go\nstraight into blah from the `\"joey\"` module.\n\n```javascript\nrequire(\"joey\").blah().content(\"hi\").listen(8080)\n```\n\nOr, create your own JSGI Middleware and hook it up:\n\n```javascript\n.use(function (next) {\n return Middleware(next);\n})\n```\n\n\nAdapters\n--------\n\nAnd there are a couple adapters for formatting responses, as in JSON.\n\n```javascript\n.json()\n.app(function () {\n return {a: 10};\n})\n```\n\nOr Node's variable inspection format.\n\n```javascript\n.inspect()\n.app(function (request) {\n return request;\n});\n```\n\nOr create your own JSGI adapter and hook it up:\n\n```javascript\n.use(function (next) {\n return Adapter(...options, next);\n});\n```\n\nThis adds a link to the chain, which will get connected to the\n``next`` application, or ``undefined`` when the chain terminates.\n\n```javascript\n.terminate(function () {\n return function (request, response) {\n // end of the chain\n // returns its own response,\n // does not forward to next application\n };\n})\n```\n\nYou can instantiate a JSGI application from the chain by terminating it.\nThe return value is an app, not a link in the chain.\n\n```javascript\n.done()\n```\n\n\nLicense\n=======\n\nCopyright (c) 2012, Motorola Mobility LLC.\nAll Rights Reserved.\n\nRedistribution and use in source and binary forms, with or without\nmodification, are permitted provided that the following conditions are met:\n\n- Redistributions of source code must retain the above copyright notice,\n this list of conditions and the following disclaimer.\n\n- Redistributions in binary form must reproduce the above copyright notice,\n this list of conditions and the following disclaimer in the documentation\n and/or other materials provided with the distribution.\n\n- Neither the name of Motorola Mobility LLC nor the names of its\n contributors may be used to endorse or promote products derived from this\n software without specific prior written permission.\n\nTHIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS \"AS IS\"\nAND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE\nIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE\nARE DISCLAIMED.
