getData()

Description​

Gets a promise with an array of tasks and links objects
info

The getData() method is a part of the RestDataProvider service intended for working with a server

Usage​

getData(): Promise<[]>

Response​

The getData() method sends a request to the server by the GET method and returns a promise with data on links and tasks. For the examples of returned objects, see tasks and linksю

Examples​

<script>
    import { Gantt } from "wx-svelte-gantt";
    import { RestDataProvider } from "wx-gantt-data-provider";

    const url = "https://some_backend_url";

    const server = new RestDataProvider(url);
    let tasks = $state(), links = $state();

    server.getData().then(data => {
        tasks = data.tasks;
        links = data.links;
    });

</script>
<Gantt
    {tasks}
    {links} />

parseDates() method​

Description: getData() applies the parseDates() method to parse dates (start, end, base_start, base_end from tasks) to Date object (as new Date(string)).

Usage: 

parseDates(task) => task

If you need to change the parsing method, you can redefine it as in the example below: create a new class for RestDataProvider, set the required parsing method using the parseDates() method, and then apply this new class for RestDataProvider. 

class MyProvider extends RestDataProvider{
    parseDates(task){
        // parse dates by method you like
        return task; 
      }
}

const restProvider = new MyProvider(serverUrl);
