Typescript & Button extensions

Typescript & Button extensions

VaielabVaielab Posts: 8Questions: 4Answers: 0

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?

    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.

    Hello again,
    Since we are talking about missing property in typescript, I might have found some other

    In this example:

    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: [{
                            extend: "collection",
                            align: "button-right",
                            background: false,
                            fade: 0,
                            className: "btnTableOption",
                            text: "Test collection",
                            buttons: [{
                                text: "test 01",
                                action: function(e, dt, node, config) {
                                    alert('test 01');
                                }
                            }]
                        }]
                    }
                ],
    });
    

    I get an error of type Object literal may only specify known properties, and '...' does not exist in type 'ButtonConfig' for align, background, fade, and buttons.
    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.
