Get progress of url download to file

For example, you can show advertisements to users until the file gets downloaded. This will help you monetize your website as well. First we are going to get the file from the server and make it available for download. So, create a button which when clicked when send an AJAX request and get the file from the server.

Also, an anchor tag must be created which will give the hypertext reference to the file when completely download in the browser. Lastly, we will add a progress bar which will show the progress of file downloaded.

Now in javascript, first we attach an onclick listener to the button and call an AJAX request to the file which needs to be downloaded. First we are creating an AJAX object. In open function, first set the method of ajax which will be GET, then the second parameter should be the complete path of file which needs to be downloaded.

We have created a variable where you can place your dynamic value. The first parameter will tell that the request must be asynchronous.

For example, when the request sent, when the request received and when the response is sent from the server. Here the readyState having value 4 and status having value indicates the completion of request. When the response is successfully received, we know that the response will be a downloadable file.

Basically it will return the URL from where the user can save the file in his computer. Note that this response is not a responseText variable which is a string.

When the object is created using that URL, we will simply assign that as hypertext reference to our anchor tag.

We are also setting the download attribute to anchor tag which tells the browser that the hypertext link to this anchor tag should be made downloadable. Since the object is created inside the browser, so it is also occupying some space.

For example, the average size of file is 1GB and the user downloads 6 or 7 files, but if you do not free the object resources, then it might end up taking a lot of space in memory of your browser. So we are freeing the resources after 60 seconds, and we need to call the revokeObjectURL function and pass the object variable in it. Now we need to create a progress bar and a text which will show the download percentage in textual format. In the above step, you can see that we have already created a progress tag, now we also need to create a span tag which shows the progress in percentage.

AJAX also provides us a method to track progress in an event called onprogress , it will have an argument and it tells the total amount of data that needs to be transferred the size of file and the which is currently been transferred so far.

We will set the total amount of data as the maximum value for the progress bar, and it continually changes the value of progress bar to the amount of data being transferred.

So you will see the progress bar gradually moves from left to right as the file gets downloaded. The speed of progress bar depends on the size of the file and your internet connection. So the progress bar has been set, now we display the percentage of the file downloaded in numbers. As we have already created a span tag in HTML and a variable for it in javascript, so we just need to calculate the percentage and display in span tag. So you may want to skip Chrome from downloading the files and use something like Internet Download Manager instead.

Here are the three steps you need to follow to figure out the full file download URL in Google Chrome :.

The download link or URL will be copied to your clipboard. It would be nice to have a progress bar to know how much has been downloaded. I found ProgressBar but I'm not sure how to incorperate the two together. I suggest you try tqdm , it's very easy to use. Example code for downloading with requests library:.

The tqdm package now includes a function designed more specifically for this type of situation: wrapattr. You just wrap an object's read or write attribute, and tqdm handles the rest; there's no messing with block sizes or anything like that. Here's a simple download function that puts it all together with requests :. It seems that there is a disconnect between the examples on the Progress Bar Usage page and what the code actually requires. Also note the use of. This has been noted in an Issue.

EDIT: Addressed comment about code clarity. Credit to leovp's answer for using the kb block size. Also python library enlighten can be used, it is powerful, provides colorful progress bars and correctly works in Linux, Windows. This code can be run here on repl.

It seems like you're going to need to get the remote file size answered here to calculate how far along you are. You could then update your progress bar while processing each chunk There is an answer with tqdm. Calculating the file size with your already downloaded size would find how far you are. Or you could use tqdm. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
