downloads.search()

The search() function of the downloads API queries the DownloadItems available in the browser's downloads manager, and returns those that match the specified search criteria.

This is an asynchronous function that returns a Promise.

Syntax

js
let searching = browser.downloads.search(query);

Parameters

Return value

A Promise. The promise is fulfilled with an array of downloads.DownloadItem objects that match the given criteria.

Browser compatibility

BCD tables only load in the browser

Examples

In general, you restrict the items retrieved using the query parameter.

Get downloads matching "query"

js
function logDownloads(downloads) {
  for (const download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

function onError(error) {
  console.log(`Error: ${error}`);
}

browser.downloads
  .search({
    query: ["imgur"],
  })
  .then(logDownloads, onError);

Get a specific item

To get a specific DownloadItem, the easiest way is to set only the id field, as seen in the snippet below:

js
function logDownloads(downloads) {
  for (const download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

function onError(error) {
  console.log(`Error: ${error}`);
}

const id = 13;

browser.downloads.search({ id }).then(logDownloads, onError);

Get all downloads

If you want to return all DownloadItems, set query to an empty object.

js
function logDownloads(downloads) {
  for (const download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

function onError(error) {
  console.log(`Error: ${error}`);
}

browser.downloads.search({}).then(logDownloads, onError);

Get the most recent download

You can get the most recent download by specifying the following search parameters:

js
function logDownloads(downloads) {
  for (const download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

function onError(error) {
  console.log(`Error: ${error}`);
}

browser.downloads
  .search({
    limit: 1,
    orderBy: ["-startTime"],
  })
  .then(logDownloads, onError);
