Typescript & Button extensions

I'm trying to recreate a simple example for the button and typescript based on your examples but I always get typescript errors.
If I try
import DataTable from "datatables.net";
import 'datatables.net-buttons';
import 'datatables.net-buttons/js/buttons.html5';
import 'datatables.net-buttons/js/buttons.print';
new DataTable('#myTable', {
layout: {
topStart: {
buttons: [
'copy', 'excel', 'pdf'
]
}
}
});
I get the error: TS2353: Object literal may only specify known properties, and 'buttons' does not exist in type 'Feature | (keyof Feature)[] | Feature[]'.
And if I try to use top level button instead like so:
import DataTable from "datatables.net";
import 'datatables.net-buttons';
import 'datatables.net-buttons/js/buttons.html5';
import 'datatables.net-buttons/js/buttons.print';
new DataTable('#myTable',{
buttons: ['copy', 'csv', 'excel', 'pdf', 'print'],
layout: {
topStart: 'buttons'
}
});
I get TS2322: Type '"buttons"' is not assignable to type 'Feature | keyof Feature | (keyof Feature)[] | Feature[] | null | undefined'.
Am I doing something wrong, or the types are incompletes for buttons?

This one I'm embarrassed to say. Sorry! I'm really surprised I didn't come across this one before. I'll get a fix out shortly and post back here with progress.

Thanks,

Hello again,
Since we are talking about missing property in typescript, I might have found some other
In this example:
I get an error of type
Object literal may only specify known properties, and '...' does not exist in type 'ButtonConfig'
foralign
,background
,fade
, andbuttons
.Based on https://datatables.net/reference/button/collection, thoses properties should be valid.
Also, in the function
action: function(e, dt, node, config)
all 4 parameters does not have types.Thank you
Hi,
Sorry I wasn't able to reply to this yesterday. I've just committed a rewrite of how the buttons are defined for Typescript which makes it more extensible for other extensions and more correct for Buttons itself.
I'll release the changes tomorrow.
