Here's an example chat room example where `"new_msg"` + * events are listened for, messages are pushed to the server, and + * the channel is joined with ok/error/timeout matches: + * + * ```javascript + * let channel = socket.channel("room:123", {token: roomToken}) + * channel.on("new_msg", msg => console.log("Got message", msg) ) + * $input.onEnter( e => { + * channel.push("new_msg", {body: e.target.val}, 10000) + * .receive("ok", (msg) => console.log("created message", msg) ) + * .receive("error", (reasons) => console.log("create failed", reasons) ) + * .receive("timeout", () => console.log("Networking issue...") ) + * }) + * + * channel.join() + * .receive("ok", ({messages}) => console.log("catching up", messages) ) + * .receive("error", ({reason}) => console.log("failed join", reason) ) + * .receive("timeout", () => console.log("Networking issue.

When attempting to create a duplicate subscription, + * the server will close the existing channel, log a warning, and + * spawn a new channel for the topic. The client will have their + * `channel.onClose` callbacks fired for the existing channel, and the new + * channel join will have its receive hooks processed as normal. + * + * ## Pushing Messages + * + * From the previous example, we can see that pushing messages to the server + * can be done with `channel.push(eventName, payload)` and we can optionally + * receive responses from the push. Additionally, we can use + * `receive("timeout", callback)` to abort waiting for our other `receive` hooks + * and take action after some period of waiting. The default timeout is 10000ms. + * + * + * ## Socket Hooks + * + * Lifecycle events of the multiplexed connection can be hooked into via + * `socket.onError()` and `socket.onClose()` events, ie: + * + * ```javascript + * socket.onError( () => console.log("there was an error with the connection!") ) + * socket.onClose( () => console.log("the connection dropped") ) + * ``` + * + * + * ## Channel Hooks + * + * For each joined channel, you can bind to `onError` and `onClose` events + * to monitor the channel lifecycle, ie: + * + * ```javascript + * channel.onError( () => console.log("there was an error!") ) + * channel.onClose( () => console.log("the channel has gone away gracefully") ) + * ``` + * + * ### onError hooks + * + * `onError` hooks are invoked if the socket connection drops, or the channel + * crashes on the server. In either case, a channel rejoin is attempted + * automatically in an exponential backoff manner. + * + * ### onClose hooks + * + * `onClose` hooks are invoked only in two cases. 1) the channel explicitly + * closed on the server, or 2). The client explicitly closed, by calling + * `channel.leave()` + * + * + * ## Presence + * + * The `Presence` object provides features for syncing presence information + * from the server with the client and handling presences joining and leaving. + * + * ### Syncing state from the server + * + * To sync presence state from the server, first instantiate an object and + * pass your channel in to track lifecycle events: + * + * ```javascript + * let channel = socket.channel("some:topic") + * let presence = new Presence(channel) + * ``` + * + * Next, use the `presence.onSync` callback to react to state changes + * from the server. For example, to render the list of users every time + * the list changes, you could write: + * + * ```javascript + * presence.onSync(() => { + * myRenderUsersFunction(presence.list()) + * }) + * ``` + * + * ### Listing Presences + * + * `presence.list` is used to return a list of presence information + * based on the local state of metadata. By default, all presence + * metadata is returned, but a `listBy` function can be supplied to + * allow the client to select which metadata to use for a given presence. + * For example, you may have a user online from different devices with + * a metadata status of "online", but they have set themselves to "away" + * on another device. In this case, the app may choose to use the "away" + * status for what appears on the UI. The example below defines a `listBy` + * function which prioritizes the first metadata which was registered for + * each user. This could be the first tab they opened, or the first device + * they came online from: + * + * ```javascript + * let listBy = (id, {metas: [first, ...rest]}) => { + * first.count = rest.length + 1 // count of this user's presences + * first.id = id + * return first + * } + * let onlineUsers = presence.list(listBy) + * ``` + * + * ### Handling individual presence join and leave events + * + * The `presence.onJoin` and `presence.onLeave` callbacks can be used to + * react to individual presences joining and leaving the app. For example: + * + * ```javascript + * let presence = new Presence(channel) + * + * // detect if user has joined for the 1st time or from another tab/device + * presence.onJoin((id, current, newPres) => { + * if(!current){ + * console.log("user has entered for the first time", newPres) + * } else { + * console.log("user additional presence", newPres) + * } + * }) + * + * // detect if user has left from all tabs/devices, or is still present + * presence.onLeave((id, current, leftPres) => { + * if(current.metas.length === 0){ + * console.log("user has left from all devices", leftPres) + * } else { + * console.log("user left from a device", leftPres) + * } + * }) + * // receive presence data from server + * presence.onSync(() => { + * displayUsers(presence.list()) + * }) + * ``` + * @module phoenix + */ + +const globalSelf = typeof self !== "undefined" ? self : null +const phxWindow = typeof window !== "undefined" ? window : null +const global = globalSelf || phxWindow || this +const DEFAULT_VSN = "2.0.0" +const SOCKET_STATES = {connecting: 0, open: 1, closing: 2, closed: 3} +const DEFAULT_TIMEOUT = 10000 +const WS_CLOSE_NORMAL = 1000 +const CHANNEL_STATES = { + closed: "closed", + errored: "errored", + joined: "joined", + joining: "joining", + leaving: "leaving", +} +const CHANNEL_EVENTS = { + close: "phx_close", + error: "phx_error", + join: "phx_join", + reply: "phx_reply", + leave: "phx_leave" +} +const CHANNEL_LIFECYCLE_EVENTS = [ + CHANNEL_EVENTS.close, + CHANNEL_EVENTS.error, + CHANNEL_EVENTS.join, + CHANNEL_EVENTS.reply, + CHANNEL_EVENTS.leave +] +const TRANSPORTS = { + longpoll: "longpoll", + websocket: "websocket" +} + +// wraps value in closure or returns closure +let closure = (value) => { + if(typeof value === "function"){ + return value + } else { + let closure = function(){ return value } + return closure + } +} + +/** + * Initializes the Push + * @param {Channel} channel -

Here's an example chat room example where `"new_msg"` + * events are listened for, messages are pushed to the server, and + * the channel is joined with ok/error/timeout matches: + * + * ```javascript + * let channel = socket.channel("room:123", {token: roomToken}) + * channel.on("new_msg", msg => console.log("Got message", msg) ) + * $input.onEnter( e => { + * channel.push("new_msg", {body: e.target.val}, 10000) + * .receive("ok", (msg) => console.log("created message", msg) ) + * .receive("error", (reasons) => console.log("create failed", reasons) ) + * .receive("timeout", () => console.log("Networking issue...") ) + * }) + * + * channel.join() + * .receive("ok", ({messages}) => console.log("catching up", messages) ) + * .receive("error", ({reason}) => console.log("failed join", reason) ) + * .receive("timeout", () => console.log("Networking issue. Still waiting...")) + *``` + * + * ## Joining + * + * Creating a channel with `socket.channel(topic, params)`, binds the params to + * `channel.params`, which are sent up on `channel.join()`. + * Subsequent rejoins will send up the modified params for + * updating authorization params, or passing up last_message_id information. + * Successful joins receive an "ok" status, while unsuccessful joins + * receive "error". + * + * ## Duplicate Join Subscriptions + * + * While the client may join any number of topics on any number of channels, + * the client may only hold a single subscription for each unique topic at any + * given time. When attempting to create a duplicate subscription, + * the server will close the existing channel, log a warning, and + * spawn a new channel for the topic. The client will have their + * `channel.onClose` callbacks fired for the existing channel, and the new + * channel join will have its receive hooks processed as normal. + * + * ## Pushing Messages + * + * From the previous example, we can see that pushing messages to the server + * can be done with `channel.push(eventName, payload)` and we can optionally + * receive responses from the push. Additionally, we can use + * `receive("timeout", callback)` to abort waiting for our other `receive` hooks + * and take action after some period of waiting. The default timeout is 10000ms. + * + * + * ## Socket Hooks + * + * Lifecycle events of the multiplexed connection can be hooked into via + * `socket.onError()` and `socket.onClose()` events, ie: + * + * ```javascript + * socket.onError( () => console.log("there was an error with the connection!") ) + * socket.onClose( () => console.log("the connection dropped") ) + * ``` + * + * + * ## Channel Hooks + * + * For each joined channel, you can bind to `onError` and `onClose` events + * to monitor the channel lifecycle, ie: + * + * ```javascript + * channel.onError( () => console.log("there was an error!") ) + * channel.onClose( () => console.log("the channel has gone away gracefully") ) + * ``` + * + * ### onError hooks + * + * `onError` hooks are invoked if the socket connection drops, or the channel + * crashes on the server. In either case, a channel rejoin is attempted + * automatically in an exponential backoff manner. + * + * ### onClose hooks + * + * `onClose` hooks are invoked only in two cases. 1) the channel explicitly + * closed on the server, or 2). The client explicitly closed, by calling + * `channel.leave()` + * + * + * ## Presence + * + * The `Presence` object provides features for syncing presence information + * from the server with the client and handling presences joining and leaving. + * + * ### Syncing state from the server + * + * To sync presence state from the server, first instantiate an object and + * pass your channel in to track lifecycle events: + * + * ```javascript + * let channel = socket.channel("some:topic") + * let presence = new Presence(channel) + * ``` + * + * Next, use the `presence.onSync` callback to react to state changes + * from the server. For example, to render the list of users every time + * the list changes, you could write: + * + * ```javascript + * presence.onSync(() => { + * myRenderUsersFunction(presence.list()) + * }) + * ``` + * + * ### Listing Presences + * + * `presence.list` is used to return a list of presence information + * based on the local state of metadata. By default, all presence + * metadata is returned, but a `listBy` function can be supplied to + * allow the client to select which metadata to use for a given presence. + * For example, you may have a user online from different devices with + * a metadata status of "online", but they have set themselves to "away" + * on another device. In this case, the app may choose to use the "away" + * status for what appears on the UI. The example below defines a `listBy` + * function which prioritizes the first metadata which was registered for + * each user. This could be the first tab they opened, or the first device + * they came online from: + * + * ```javascript + * let listBy = (id, {metas: [first, ...rest]}) => { + * first.count = rest.length + 1 // count of this user's presences + * first.id = id + * return first + * } + * let onlineUsers = presence.list(listBy) + * ``` + * + * ### Handling individual presence join and leave events + * + * The `presence.onJoin` and `presence.onLeave` callbacks can be used to + * react to individual presences joining and leaving the app. For example: + * + * ```javascript + * let presence = new Presence(channel) + * + * // detect if user has joined for the 1st time or from another tab/device + * presence.onJoin((id, current, newPres) => { + * if(!current){ + * console.log("user has entered for the first time", newPres) + * } else { + * console.log("user additional presence", newPres) + * } + * }) + * + * // detect if user has left from all tabs/devices, or is still present + * presence.onLeave((id, current, leftPres) => { + * if(current.metas.length === 0){ + * console.log("user has left from all devices", leftPres) + * } else { + * console.log("user left from a device", leftPres) + * } + * }) + * // receive presence data from server + * presence.onSync(() => { + * displayUsers(presence.list()) + * }) + * ``` + * @module phoenix + */ + +const globalSelf = typeof self !== "undefined" ? self : null;
