FileSaver.js | An HTML5 saveAs() FileSaver implementation | Frontend Framework library

I've studied all of the SO Similar Questions about this problem, a few were helpful, but did not directly address the saving of an xlsx file to the local Win10 downloads folder.

The xlsx file sits on a CentOS 7 server. If I use Filezilla to copy it to Win10, it's fine.

Looking at the component code below, I am reading the xlsx from the server and getting its base64Str, which matches exactly what I used to store the file. I create a blob fine, but FileSaver, saves the Win10 file with its contents as the base64Str, instead of a an xlsx binary. Can FileSaver save binary content, or only text?

Thanks for helping!

Component Code

So I'm trying out Dom-to-Image but ran into a deadend. I have this div with a fixed width and height of 700px and 500px respectively. This is the div which I want to take a screenshot of with Dom-to-Image plugin.

When the div is left-aligned on the viewport, the screen capture is perfect and I can download the image. But if I make the div center with margin: 0 auto;, then I get one-third of the screenshot and not the full image.

Here's the issue when it is centered:

What I want:

No matter where my div is placed, I only want to take the screenshot of that full div. How can I do that?

Here's the code:

I want to use fileSaver.js to click a button and save a binary blob (type: "application/octet-stream"). But i don´t know how to save the blob the way i need it to be.

The final file (example.mod) needs to have the following sequence:

• 8 (the number of bytes for the next peace of information, integer number)
• (a tag name with 8 characters)
• 3 (the number of points)
• [A,10.5,10,10] (a point: an array with a letter and 3 floating numbers)
• [B,20,10,0.7] (a point: an array with a letter and 3 floating numbers)
• [C,10,20.3,10] (a point: an array with a letter and 3 floating numbers)
• 9 (the number of bytes for the next peace of information, integer number)
• (a tag name with 9 characters)

I´ve found some examples saving "text/plain" or "image/png", but nothing that I could figure out how to apply in my case.

I've made this CodePen showing what I´m trying to do, but the resulting file is not what expected! it returns a file like that (all the information is visible as if was a text file):

I am trying to download and save a large zip file. The zip file is possibly larger than the heap, so I want to use a stream to avoid java.lang.OutOfMemoryError: Java heap space error.

Also, the large zip file is generated on request, so I would like to delete the file after downloading it.

I am making a digit drawing tool that uses the setTransform() function to distort/skewer a given digit drawn by the user and download them. Currently, the images seem to have not been cleared out of the frame before a new image is drawn on the canvas.

Here is an example of what I mean:

Here is the code related to manipulating the image and downloading it:

Recently, I have been asked to make a tool that should automatically generate .docx files using a given template once we feed data to it. After some thinking, I eventuall opted for the docxtemplater, and I did manage to generate a .docx file, with the core code like this:

I'm writing a bookmarklet that is supposed to take a screenshot of an SVG chart and save it as a PNG image. I'm testing this with the latest Chrome browser.

Here is the URL of the page containing the chart: https://data.oecd.org/gdp/real-gdp-forecast.htm The chart I want to capture and save as PNG is the large one in the top half of the page. It can be identified by the CSS class ddp-chart-inner.

The code in the bookmarklet is here: https://pastebin.com/raw/cduvdC6e (pastebin because GitHub sets some CSP header that doesn't allow the code to be injected into another website).
