How to use the element to create download links
If you want to create your own download links for files on your website or blog, you can use the should indicate the link's destination.
The most important attribute for creating download links is the href attribute. This specifies the URL of the file that you want to download. For example:
This will create a link that will download the file.pdf from the example.com website when clicked.
However, this will not always work as expected. Depending on the browser and the file type, the browser may try to open the file in a new tab or window, or display a dialog box asking the user to save or open the file. To avoid this, you can use the download attribute. This tells the browser to download the file instead of opening it, and optionally suggests a filename for the downloaded file. For example:
This will create a link that will download the file.pdf from the example.com website and save it as report.pdf on the user's computer.
Another attribute that you can use for creating download links is the referrerpolicy attribute. This controls how much referrer information (the page from which the user navigated to the file) is sent along with the request. This can affect the privacy and security of your users and your website. For example:
This will create a link that will download the file.pdf from the example.com website and save it as report.pdf on the user's computer, without sending any referrer information to the example.com server.
There are other values that you can use for the referrerpolicy attribute, such as origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url, or an empty string. You can read more about them on MDN.
How to use the downloads.download() API to download files programmatically
To use this API, you need to have the "downloads" permission in your manifest.json file. Then you can call the downloads.download() method with an object that contains the following options:
urlThe URL of the file to be downloaded. This is required.
filenameThe file path and name relative to the default downloads directory. This is optional.
conflictActionThe action to take if there is a filename conflict. This can be "uniquify", "overwrite", or "prompt". The default is "uniquify".
headersAn array of objects that specify additional HTTP headers to be sent with the request. Each object has a name and a value property.
methodThe HTTP method to use for the request. This can be "GET" or "POST". The default is "GET".
bodyThe body of a POST request. This is optional.
saveAsA boolean value that indicates whether to show a save dialog to the user. The default is false.
For example, if you want to download a file from and save it as report.pdf in a subfolder called "reports" in your downloads directory, you can use this code:
downloads.download( url: " "reports/report.pdf");
This will return a promise that resolves with an integer ID for the new download item, or rejects with an error message if something goes wrong.
