Opening and downloading files

The widget provides special actions for opening and downloading files:

• open-file
• download-file

You need to listen to these actions using the api.on() method and call the required functions for these actions.

Example:

<script>
  import { Filemanager } from "wx-svelte-filemanager";

  const server = "https://some-backend-url";

  function getLink(id, download) {
    return server + "/direct?id=" + encodeURIComponent(id) + (download ? "&download=true" : "");
  }

  function loadData(id, api) {
    fetch(server + "/files/" + encodeURIComponent(id))
      .then((data) => data.json())
      .then((data) => {
        api.exec("provide-data", {
          id,
          data,
        });
      });
  }

  let rawData = $state([]);
  fetch(server + "/files")
    .then((data) => data.json())
    .then((data) => (rawData = data));

  const init = (api) => {
    api.on("download-file", (ev) => {
      window.open(getLink(ev.id, true), "_self");
    });

    api.on("open-file", (ev) => {
      window.open(getLink(ev.id), "_blank");
    });

    api.on("request-data", ({ id }) => loadData(id, api));
  }

</script>

<Filemanager {init} data={rawData} />
