1/*2 * @function steal-socket.delay-io delay-io3 * @parent steal-socket.io4 * @type {Function}5 * @hide6 *7 * @description Wrap `socket-io` to delay establishing a connection for testing purposes.8 *9 * @signature `delayIO( io )`10 *11 * This wrapper helps with testing and demoing applications that use `socket.io` for real-time communication.12 * Often some modules that use `socket.io` call it to establish a socket connection immediately. This13 * makes mocking of `socket.io` impossible. The wrapper delays the creation of socket connection till `StealJS`14 * [is done](https://stealjs.github.io/stealjs/docs/steal.done.html) loading all the modules (including ones where we can mock15 * `socket.io` for testing).16 *17 * ```18 * var delayIO = require("steal-socket.io/delay-io");19 * var socketIO = require("socket.io-client/dist/socket.io");20 * var io = delayIO( socketIO );21 *22 * io("localhost");23 * ```24 * @param {module} io The SocketIO client module. Usually, it is `socket.io-client/dist/socket.io`.25 *26 * @body27 *28 * ## How it works29 *30 * The `delay-io` wrapper returns `io`-like function that resolves in a `delayedSocket`. The `delayedSocket` is31 * a replacement for `io.Socket` and acts as a proxy for it.32 *33 * Initially the wrapper records all calls to `io` and its socket into a _FIFO storage_, and then, when `StealJS`34 * is done with loading all modules, it replays the recorded calls against the real `io` and its socket.35 *36 * After replaying the wrapper directly proxies all the subsequent calls.37 *38 * ## Usage39 *40 * Import `steal-socket.io` which includes this wrapper as its part, or directly import `steal-socket.io/delay-io`41 * to use just this wrapper.42 *43 * Lets say we have an application `myApp.js` that uses `socket.io` and tries to establish the connection right during44 * module evaluation. We import `steal-socket.io` in our app instead of `socket.io-client/dist/socket.io`:45 * ```46 * var io = require("steal-socket.io");47 *48 * var messages = [];49 *50 * var socket = io("localhost");51 * io.on("messages", function(m){52 * messages.push(m);53 * });54 *55 * module.exports = {56 * messages: messages57 * };58 * ```59 *60 * We now create a module `myFixtureSocket.js` that mocks `socket.io` server responses, e.g. using `can-fixture-socket`:61 * ```62 * var io = require("socket.io-client/dist/socket.io");63 * var fixtureSocket = require("can-fixture-socket");64 * var mockSocket = new fixtureSocket( io );65 * mockSocket.on("connect", function(){66 * mockSocket.emit("messages", "some messages");67 * });68 * ```69 *70 * And then we can test our application like this:71 * ```72 * require("myFixtureSocket");73 * var myApp = require("my-app.js");74 *75 * QUnit.test(function(){76 * assert.equal(myApp.messages.length, 1, "Contains one message received from socket server.");77 * });78 * ```79 */80var steal = require("@steal");81var ignore = require("./ignore-zone");82module.exports = delayIO;83/*84 * Switch debugging on/off.85 * TODO: http://socket.io/docs/logging-and-debugging/#available-debugging-scopes86 * @type {Boolean}87 */88var DEBUG = false;89/*90 * `fifoSockets` contains FIFO and a placeholder for `realSocket` per URL.91 * A FIFO is a storage for calls to io.Socket to be replayed when steal is done and we can create a real socket.92 * The first element will be io and its arguments so that we could create a real socket later.93 * ```94 * // The following app:95 * var socket = io("localhost");96 * socket.on("messages", function(m){ console.log(m); })97 * socket.emit("hello", {});98 *99 * // will create:100 * fifoSockets = {101 * localhost: {102 * url: "localhost",103 * realSocket: null,104 * fifo: [105 * [io, ["localhost"]],106 * ["on", ["messages", function(m){ console.log(m); }]],107 * ["emit", ["hello", {}]]108 * ]109 * }110 * }111 * ```112 * @type {Object}113 */114/*115 * Delayed socket - a proxy for socket method calls, so that we can record early calls to `fifo` and replay them after.116 * @param io117 * @returns {{on: function, emit: function, ...}}118 */119function delayedSocket(fifoSocket){120 var delayedSocketBase = {121 __delayedSocket: true,122 get connected () {123 var realSocket = this.fifoSocket.realSocket;124 return !!realSocket && realSocket.connected;125 },126 get disconnected () {127 return !this.connected;128 }129 };130 var methods = [131 'on',132 'off',133 'once',134 'emit',135 'removeListener',136 'addListener',137 'open',138 'connect',139 'close',140 'disconnect'141 ];142 var delayedSocket = methods.reduce(function(acc, method){143 acc[method] = function(){144 var realSocket = fifoSocket.realSocket;145 var fifo = fifoSocket.fifo;146 var url = fifoSocket.url;147 if (realSocket){148 debug('delay-io("' + url + '"): realSocket ' + method);149 if (!realSocket[method]){150 console.warn('steal-socket.io: method ' + method + ' is undefined for realSocket');151 } else {152 realSocket[method].apply(realSocket, arguments);153 }154 } else {155 debug('delay-io("' + url + '"): record ' + method + '("' + arguments[0] + '", ...)');156 fifo.push([method, arguments]);157 }158 };159 return acc;160 }, delayedSocketBase);161 delayedSocket.io = {162 uri: fifoSocket.url,163 engine: ['on', 'off'].reduce(function (acc, method) {164 acc[method] = function (event, handler) {165 if (fifoSocket.realSocket) {166 return fifoSocket.realSocket.io.engine[method](event, handler);167 }168 };169 return acc;170 }, {})171 };172 delayedSocket.fifoSocket = fifoSocket;173 return delayedSocket;174}175/*176 * Replays calls that were recorded to `fifo`.177 * @param fifo178 * @returns {Function}179 */180var hasReplayed = false;181function replay(fifoSockets){182 return function(){183 debug('+++++ delay-io: replay!');184 Object.keys(fifoSockets).forEach(function(url){185 replayFifoSocket(fifoSockets[url]);186 });187 hasReplayed = true;188 };189}190function replayFifoSocket(fifoSocket){191 var url = fifoSocket.url,192 io = ignore(fifoSocket.io),193 args = fifoSocket.args,194 realSocket = fifoSocket.realSocket = io.apply(this, args);195 fifoSocket.fifo.forEach(function(pair){196 var method = pair[0],197 args = pair[1];198 debug('delay-io("' + url + '"): replay ' + method + '("' + args[0] + '", ...)');199 realSocket[method].apply(realSocket, args);200 });201}202// TODO: make it to work the same way as socket.io debugging http://socket.io/docs/logging-and-debugging/#available-debugging-scopes203function debug(msg){204 if (DEBUG){205 console.log(msg);206 }207}208var fifoSockets = {};209function delayIO(io){210 steal.done().then(replay(fifoSockets));211 return function (url, options) {212 var urlId = url === '' ?
