Introduction

Function-administration module.

fncRsv is a module that helps you use function whenever you want. It's simple, and undependent from other modules.

This module run async, which your server (or browser) can do other works while module standby. Notice that your server (or browser) can't afford this module if you register lots of functions at once.

Installing

Use npm:

$ npm install fncrsv

Use unpkg CDN:

<script src="https://unpkg.com/fncrsv@latest/lib/fncRsv.min.js"></script>

Usage

0.default

usage:

fncRsv(timeType, periodNum, timeValue, function);

Such parameter's data type exclude 'timeType' is different due to 'timeType'

1.periodic

usage:

fncRsv("periodic", periodNum, timeValue, function);

data type

periodNum: Number
timeValue: Number
reservFnc: Function

data role

periodNum: Number that you want to run function (0: unlimit)
timeValue: Interval that you want to run function
reservFnc: Function that you want to run periodic

example:

// example1: run function looping periodically at aspecific time interval

const testFunction = function () { 
    console.log(`Hello, fncRsv! Logged time is ${Date()}`);
}

const regMsg = fncRsv("periodic", 5, 1000, testFunction);
console.log(regMsg); // Function successfully registered. ~

// (1 seconds later)

// Hello, fncRsv! Logged time is ~ (repeat 5 times)

2.specific

usage:

fncRsv("specific", periodNum, timeValue, function);

data type

periodNum: Number
timeValue: Object
reservFnc: Function

structure of 'timeValue'

timeValue: {
    optionSetter: "HH",
    optionValue: 21
}

(ex: If you want to run function at 21:00
    -> timeValue: {
        optionSetter: "HH",
        optionValue: 21
    }
)

data role

periodNum: Number that you want to run function (0: unlimit)
timeValue: {
    optionSetter: option that you want to set basis ("HH" || "MM" || "SS")
    optionValue: value that set basis
}
reservFnc: Function that you want to run periodic

example:

// example2: run function looping periodically at aspecific time

const testFunction = function () { 
    console.log(`Hello, fncRsv! Logged time is ${Date()}`);
}



const regMsg = fncRsv("specific", 0, {
    optionSetter: "SS",
    optionValue: 40
}, testFunction);
console.log(regMsg); // Function successfully registered. ~

// (everytime when second correct '40')

// Hello, fncRsv! Logged time is ~ (repeat permanent)

3.onetime

usage:

fncRsv("onetime", periodNum, timeValue, function);

data type

periodNum: NULL (if input, it will be ignored)
timeValue: String (YYYYMMSSHHMMSS)
reservFnc: Function

data role

periodNum: null (no need in this option)
timeValue: Time that run function (YYYYMMDDHHMMSS)
reservFnc: Function that you want to run periodic

example:

// example3: run function at specific time just once

const testFunction = function () { 
    console.log(`Hello, fncRsv! Logged time is ${Date()}`);
}

const regMsg = fncRsv("onetime", null, "20200808201600", testFunction);
console.log(regMsg); // Function successfully registered. ~

// (when '2020-08-08 20:16:00')

// Hello, fncRsv! Logged time is Sat Aug 08 2020 20:16:00 GMT+0900 (GMT+09:00)
