NodeJS -> B4X [job already given!]

ilan · Apr 24, 2024

hi

i would like to convert this NodeJS library to B4x:

kosher-zmanim

A library for calculating zmanim, based on KosherJava.. Latest version: 0.8.2, last published: 3 years ago. Start using kosher-zmanim in your project by running `npm i kosher-zmanim`. There are 3 other projects in the npm registry using kosher-zmanim.

www.npmjs.com

this is the app.js i run using NodeJS and i am getting what i want:

B4X:

const KosherZmanim = require("kosher-zmanim");

var date = new Date();

    const options = {
        date: date.toISOString().substr(0, 19),
        timeZoneId: "Asia/Jerusalem",
        locationName: "Haifa",
        latitude: Number.parseFloat("32.817280"),
        longitude: Number.parseFloat("34.988762"),
        elevation: Number.parseFloat("0"),
        complexZmanim: true,
    };
                  
    const json = KosherZmanim.getZmanimJson(options);
    
    console.log(JSON.stringify(json, null, 2));

returned Json String:

now i would like to use it in b4x without running a server. i would like to convert the whole library so i can run the function inside b4x OFFLINE.

how much would you charge for it? you can send me pm.

thanx, ilan

EDIT: job is currently given to @tummosoft . If there will be any changes i will update the thread. Thanks

What is the result of this? What kind of Datestring is it/how does it look like?

Its a json object that is converted to string
I have included the result in the first post

returned Json String

It still does not answer my question. WHAT exactly was the INPUT to the routine?

ilan · Apr 24, 2024

oh sorry @DonManfred you asked for the DateString i read data string.

the date looks like this:

"2024-04-01"

YYYY-MM-DD

it can also include time but this is not important. but the dateformat is important.

"2024-04-01"

YYYY-MM-DD

But the code is expecting a 19 bytes long String!?

B4X:

date: date.toISOString().substr(0, 19)

I guess date is the datefield you entered 2024-04-01 into.
What is the "output" of this code?

DonManfred said:

in the example code above i entered a date including time like this:

2024-04-24T13:14:55

but entering the date alone is good enough as long as it is like this: YYYY-MM-DD (month and day needs to be 2 DIGITS!!)

DonManfred said:

2024-04-24T13:14:55

you can try it here:

B4X:

<!DOCTYPE html>
<html>
<body>

<h1>JavaScript Dates</h1>
<h2>Using new Date()</h2>
<p>Create a new date object with the current date and time:</p>

<p id="demo"></p>

<script>
var date = new Date();
document.getElementById("demo").innerHTML = date.toISOString().substr(0, 19);
</script>

</body>
</html>

enter the code above here:

I´m not bad if you already have one who is doing it for you

ilan · Apr 24, 2024

Ok thanks @DonManfred. Actually 2 members offer their service i will start with @tummosoft and give him the opportunity to do the job.
If there will be any changes i will update the thread thank you all
