    Can you create a minimal git repo or Stackblotz showing the issue please? I'll be able to debug that.

    Thanks,
    Allan

    Thank you. You have:

    import { Component } from '@angular/core';
    
    @Component({
        selector: 'app-root',
        templateUrl: './app.component.html',
        styleUrls: ['./app.component.scss']
    })
    export class AppComponent {
        title = 'Angular15App';
        dt: DataTables.DataTable;
    }
    

    However, there is no DataTables type. Did you try to define it globally somewhere or something?

    I think you need something like:

    import DataTable from 'datatables.net';
    

    And then use:

    dt: DataTable<any>
    

    but that gives an error as well:

    Property 'dt' has no initializer and is not definitely assigned in the constructor

    I don't know what dt is meant to be? Is it a DataTables API instance, or something else?

    Allan, it works with an older version of the datatables. Also in places in our code we had declared things like

    const settings: DataTables.ColumnSettings[]

    we now have to change to to 'any' so its taking some type safety away.

    That looks like third party types from definitely typed? Did you include @types/datatables.net perhaps? That wasn't written nor supported by us. I'd suggest removing that package since DataTables includes its own, up to date and supported, types now.

    edit - yes I see that that package was included. I'd suggest deleting it and using the types DataTables provides. The exported ConfigColumns type for example is our column configuration type.

    Thanks Alan, is there an example of using these types in angular/typescript?

  • allanallan Posts: 63,414Questions: 1Answers: 10,454 Site admin

    In Typescript yes - for example.

    In Angular, no, not yet sorry. I hope to look into a full first class component for Angular next year. There is this third party project for Angular / DataTables integration, but it isn't something I've used myself, so I can't offer any support for it I'm afraid.
