`iflive`

A Javascript client for the Infinite Flight simulator Live API version 2

iflive is currently at version 0.9.3 which is considered a release candidate for version 1.0.0. It is being released to allow for input and feedback from the Infinite Flight community and to identify major issues before the first formal release.

Installing `iflive`

iflive is available as a Node module on npmjs.com and can simply be installed with:

npm install iflive

Using `iflive`

Including `iflive` in your scripts/applications

To use iflive you need to include it in your scripts:

let IFL = require("iflive");

Or, if you aren't installing with npm then you can simply clone this repository and directly reference iflive.js:

let IFL = require("/path/to/iflive.js");

Initialisation

To initialise iflive and connect to an Infinite Flight device you use the init function. The init function takes the following arguments:

init(apikey, {params}, callback)

apikey is the API key for the Infinite Flight Live API which you have received from Infinite Flight
params is an optional parameter which allows you to configure and control various aspects of the module, including:
- callback is a boolean value indicating if callback functions should be used to return values instead of the standard iflive event model; default is false
- enableLog is a boolean value to enable/disable logging in the Module; default is false
- loggingLevel is an integer value for logging level in the module (2: INFO, 1: WARN, 0: ERROR); default is 0 (ERROR)
callback is the callback function to invoke once initialised assuming callback is set to true

Example :

IFL.init(
  `abcdefghijk...`,
  {
    "enableLog": true,
    "loggingLevel": 1
  }
);

By default, if callback is false, after initialisation the IFLinit event will be fired and can be used to respond to the initialisation:

IFL.on("IFLinit", function(msg) {
  //TAKE ACTION HERE AFTER INITIALISATION
});

A single argument is passed with the IFLinit event -- a message indicating initialised

Calling the API

The primary way of interacting with the Infinite Flight Live API with iflive is done through the call method of iflive. The syntax for the call method is:

IFL.call(COMMAND_NAME, PARAMETERS, POST_DATA, CALLBACK_FUNCTION);

The four arguments are:

COMMAND_NAME: The name of an iflive command as discussed below.
PARAMETERS: An object containing one or more parameters required by the command being invoked.
DATA: An object containing data to be sent as JSON in a POST request to the Live API for commands which require POST requests with JSON data in the body of the request.
CALLBACK_FUNCTION: A function to invoke when the Live API responds to the command if you have initialised iflive to use callbacks instead of events. A JSON object will be returned as an argument to the callback function.

For instance, to retrieve a list of active sessions you could use:

IFL.call("sessions", {}, {});

Or, to retrieve a session's flights you could use:

IFL.call("flights", { sessionId: SESSION_ID_HERE }, {});

Or, to retrieve details of a list of users by their Discourse username:

IFL.call("users", { }, {
  discourseNames: [
    'USERNAME1',
    'USERNAME2',
    ...
  ]
});

When calling the API, the iflive module treats this as an asynchronous activity to avoid blocking while waiting for a response from the Infinite Flight Live API. By default, when ifclive receives a response from the API, by default it will emit an IFLdata event and return a data object containing two properties:

command: The name of the command being returned
params: An object containing one or more parameters passed to the command when it was invoked
data: An object containing data sent as JSON in a POST request to the command when it was invoked
result: The value returned by Infinite Flight for the command

In this case, we could simply log the data returned by the event like this:

IFL.on("IFLdata", function(data) {
  console.log(data);
});

If we had sent the sessions command as in the example above, the resulting console output displayed when we receive the associated IFLdata event would look like this:

{
  command: 'sessions',
  params: {},
  data: {},
  result: [
    {
      maxUsers: 1500,
      id: '6a04ffe8-765a-4925-af26-d88029eeadba',
      name: 'Training Server',
      userCount: 209,
      type: 1
    },
    {
      maxUsers: 1500,
      id: '7e5dcd44-1fb5-49cc-bc2c-a9aab1f6a856',
      name: 'Expert Server',
      userCount: 460,
      type: 1
    },
    {
      maxUsers: 2000,
      id: 'd01006e4-3114-473c-8f69-020b89d02884',
      name: 'Casual Server',
      userCount: 172,
      type: 0
    }
  ]
}

iflive offers an alternative to events using callback functions which is discussed below

Callbacks

If you prefer to use callbacks instead of events to respond to data returned by the API, you can specify the callback option as true when initialisating iflive:

IFL.init(
  `abcdefghijk...`,
  {
    "enableLog": true,
    "loggingLevel": 1,
    "callback": true
  },
  () => {
    console.log("iflive initialised");
  }
);

Once initialised in this way, you can make calls to the API and provide callback functions for processing the response:

IFL.call("sessions", {}, {}, (res) => {
  console.log(res);
});

The response from the API is passed to the callback function and in this example the following output will be logged:

[
  {
    maxUsers: 1500,
    id: '6a04ffe8-765a-4925-af26-d88029eeadba',
    name: 'Training Server',
    userCount: 203,
    type: 1
  },
  {
    maxUsers: 1500,
    id: '7e5dcd44-1fb5-49cc-bc2c-a9aab1f6a856',
    name: 'Expert Server',
    userCount: 466,
    type: 1
  },
  {
    maxUsers: 2000,
    id: 'd01006e4-3114-473c-8f69-020b89d02884',
    name: 'Casual Server',
    userCount: 180,
    type: 0
  }
]

Caching

iflive has an in-built caching mechanism which keeps the last fetched values for commands so that they can be refetched (if needed) without sending a request back to the server. A combination of information is used to form unique keys for storing cached values:

For GET requests, the command name plus the query parameters object (as passed to call) are combined to form the key for storing the cache value
For POST requests, the command name plus the post data object (as passed to call) are combined to form the key for storing the cache value

Whenever you fetch a value with call it will be added to the cache or, if a value already exists for the cache key, the value will be updated with the new value returned by the Live API.

To fetch values from the cache, iflive provides the get function as an alternative to the call function. Where call will always invoke the Live API to fetch the value, get will check the cache and return a cached value if available. Where one is not available, it will invoke call to fetch the value. The get function takes the same arguments as the call function:

IFL.get(COMMAND_NAME, PARAMETERS, POST_DATA, CALLBACK_FUNCTION);

The four arguments are:

COMMAND_NAME: The name of an iflive command as discussed above.
PARAMETERS: An object containing one or more parameters required by the command being invoked.
DATA: An object containing data to be sent as JSON in a POST request to the Live API for commands which require POST requests with JSON data in the body of the request.
CALLBACK_FUNCTION: A function to invoke when the Live API responds to the command if you have initialised iflive to use callbacks instead of events. A JSON object will be returned as an argument to the callback function.

The cache can prove particulately useful when working with polling as described below.

Polling

iflive includes a polling mechanism which you can use to set up automatic polling of a specific API command on a fixed schedule. This is useful where you need to regularly fetch updated data from the API.

As with caching, the poller is set up for a unique combination of the command name plust either query parameter objects or post data objects:

For GET requests, the command name plus the query parameters object (as passed to call) are combined to form the key for creating the poller
For POST requests, the command name plus the post data object (as passed to call) are combined to form the key for creating the poller

The poll function is used to set up polling for any command:

IFL.poll(COMMAND_NAME, PARAMETERS, POST_DATA, INTERVAL, CALLBACK_FUNCTION);

The four arguments are:

COMMAND_NAME: The name of an iflive command as discussed above.
PARAMETERS: An object containing one or more parameters required by the command being invoked.
DATA: An object containing data to be sent as JSON in a POST request to the Live API for commands which require POST requests with JSON data in the body of the request.
INTERVAL: An integer specifying the interval for polling the command in milliseconds.
CALLBACK_FUNCTION: A function to invoke when the Live API responds to the command if you have initialised iflive to use callbacks instead of events. A JSON object will be returned as an argument to the callback function.

For instance, to fetch a list of active sessions every 30 seconds using callbacks you could use:

IFL.poll("sessions", {}, {}, 30000, (res) => {
  console.log(res);
});

Or, to retrieve a session's flights every five seconds:

IFL.poll("flights", { sessionId: SESSION_ID_HERE }, {}, 5000, (res) => {
  console.log(res);
});

Or, to retrieve details of a list of users by their Discourse username every minute:

IFL.poll("users", { }, {
  discourseNames: [
    'USERNAME1',
    'USERNAME2',
    ...
  ]
}, 60000, (res) => {
  console.log(res);
});

If you need to cancel polling for a specific command you use the clear function:

IFL.clear(COMMAND_NAME, PARAMETERS, POST_DATA);

The three arguments are:

COMMAND_NAME: The name of an iflive command as specified when calling poll.
PARAMETERS: An object containing one or more parameters required by the command being invoked as specified when calling poll.
DATA: An object containing data to be sent as JSON in a POST request to the Live API for commands which require POST requests with JSON data in the body of the request as specified when calling poll.

For instance, to stop polling a session's flights every five seconds as defined above, we would use:

IFL.clear("flights", { sessionId: SESSION_ID_HERE }, {});

Utility Functions

iflive offers two utility functions:

aircraft: Returns an aircraft type name when passed the ID of the aircraft type
livery: Returns an aircraft livery name when passed the ID of the aircraft livery

These functions are designed to be used with the aircraft type and livery IDs returned by the Live API.

For instance, you can fetch the aircraft type name for the aircraft ID 230ec095-5e36-4637-ba2f-68831b31e891 and output to the console as follows:

console.log(IFL.aircraft("230ec095-5e36-4637-ba2f-68831b31e891"));

This will output the following:

Airbus A350

Similarly, if you want output the name of the livery with ID cd8085a5-015b-433f-a623-6a59de2523ba to the console you could use:

console.log(IFL.livery("cd8085a5-015b-433f-a623-6a59de2523ba"));

This will output the following:

Air France

These functions use the aircraft and livery CSV data from Infinite Flight's @carmichaelalonso available on GitHub. The current version of iflive uses the data provided for Infinite Flight 22.02.

Dependencies

iflive depends on the following npm/Node packages:

request - Simplified HTTP client for connecting to the UpCloud endpoints
events - core Node module: For emitting events to calling scripts

iflive also used the aircraft and livery CSV data provided by Infinite Flight's @carmichaelalonso.
