boss-intervals

If you need to manage intervals/timers/loops ( expecially on raspberry side, it's specially useful in use in graceful shutdown of the process ) this module is for you . with this simple module you can create intervals and timers and have a common manager for everythings. .

An example to use in graceful shutdown

var intervals = require("boss-intervals");
 
intervals.addTimer(() => {
    console.log("timer 1");
},1000);
 
intervals.addTimer(() => {
    console.log("timer 2");
},200);
 
intervals.startTimers();
 
process.on('SIGINT',() => {
    intervals.stopTimers();
    process.exitCode = 0;
});

example with timeout

var intervals = require("boss-intervals");
 
intervals.addTimer(() => {
    console.log("timer 1");
},1000);
 
intervals.addTimer(() => {
    console.log("timer 2");
},200);
 
intervals.startTimers();
 
setTimeout(() => {
    intervals.stopTimers();
},5000);

You can also use a special events in every intervals/timers

var intervals = require("boss-intervals");
 
var timer = intervals.addTimer(() => {
    console.log("timer 1");
},1000);
 
// Before the timer is initializated and ready to start
timer.onInit(function(){
    console.log("onInit");
});
 
// before the first line of code of your function (for every interaction)
timer.onBegin(function(){
    console.log("onBegin"); 
});
 
// after the last line of code of your function (for every interaction)
timer.onFinish(function(){ 
    console.log("onFinish");
});
 
// when the timer is terminated ( if you shutdown the timer 
// when it is ongoing the timer will be terminated and than 
// will be catched this event )
timer.onClose(function(){ 
    console.log("closed");
});
 
 
setTimeout(() => {
    intervals.stopTimers();
},10000);

The example below show how you can manage if a variable is free to use

var intervals = require("boss-intervals");
var a = 1;
 
var timer_1 = intervals.addTimer(() => {
    a++;
    console.log(a);
},1);
 
var timer_2 = intervals.addTimer(() => {
    if(timer_1.isRunning()) //Check if a timer is running
        console.log("var a it's busy from timer_1");
    else
        a = 1;
},1);
