Hi All,

I've read some threads about adding library js, but didn't get work. I want to use library from this site:  
[http://praytimes.org/manual](http://praytimes.org/manual)  
and library is  
[praytimes](http://praytimes.org/code/v2/js/PrayTimes.js)

I've add to my function global

And try to using it as a function. But still not working.

var PT = new PrayTimes('ISNA');  
var times = PT.getTimes(new Date(), [43, -80], -5);

So you better create a new instance first?

Hi, Sir  
After add global.get context:  
var PrayTimes = global.get('prayTimes');  
var PT = new PrayTimes('ISNA');  
var times = PT.getTimes(new Date(), [43, -80], -5);  
msg.payload = times.sunrise;  
return msg;

Here is the output

Hi @mrizkywiguna

The file you are trying to use is not packaged as a node.js module - so you cannot `require` it in your settings file.

If you edit `PrayTimes.js` and add the following line to the end of it:

```auto
module.exports = PrayTimes;

```

Then restart Node-RED, your Function should work.

Hi Sir,

Another questions, how to put this code into function?

> prayTimes.tune( {sunrise: -1, sunset: 3.5} );

You'll have to explain a bit more about what you mean. I don't know anything about the library you are using, I have never seen it before today.

So when you ask how to put that code into a function, all I can say is just copy and paste it in... but I assume that isn't the sort of answer you are looking for.

I'm sorry, Sir.

Actually the code is working now. But the "time" results need some tune, because it's different from the actual. Based on the manual, this function is for tune the minutes:

Hi Nick,  
Now i'm using this code for some adjusting. Maybe not the best way, but now I can tune it.

```auto
