exiftool-vendored.js VS jimp

Know that although ExifTool is written in perl, you can run it in "batch mode" which makes it quite fast--only a couple of ms to parse a file. I've written an open source library to manage the subprocesses for you if you're using node.js (and I also wrote the ruby variant ages ago):

https://github.com/photostructure/exiftool-vendored.js

The frontend is in Vue. Both the FE and BE are in TypeScript.

Parallelism is provided by https://github.com/photostructure/batch-cluster.js/

Metadata reads and writes are via https://github.com/photostructure/exiftool-vendored.js/

if you're looking into doing stuff with EXIF, there's a really good library that's also typed: https://github.com/photostructure/exiftool-vendored.js

I needed a good Node wrapper for ExifTool and wrote https://github.com/photostructure/exiftool-vendored.js

When I saw how slow it is to fork child processes in Windows, I then realized I wanted to run ExifTool in "stay-open" mode, which meant I needed to manage 1 or more long-lived child processes that communicate via stdin/stdout, so I wrote https://github.com/photostructure/batch-cluster.js

I also really missed scala's `lazy` operator, so I built that (and several other small, helpful functions/classes) that I documented here: https://photostructure.com/coding/uncertain-lazy-forgetful-a...

QR codes are a convenient and efficient way to store and share information. Reading and writing QR codes can easily be done with Node.js, the popular JavaScript runtime environment. In this article, we will go over the steps for reading and writing QR codes in Node using three popular libraries: qrcode-reader and jimp for reading QR codes, and qrcode for generating QR codes.

If you're more into Javascript, jimp works, too.

I've used Jimp before - probably other libs like it :)

I’m not sure how to best answer but I have used jimp recently, and liked it.

As a seasoned sharp user, discovered jimp . Had to convert an image to BMP once and sharp doesn't support that format.

Recently I wrote a few posts on my personal blog with lots of pictures. To save on bandwidth and load time it's very important to reduce the size of the images. Which until recently I did manually in Preview, MacOS. It was a rather cumbersome manual process, that I automated with the help of Node.js/ExpressJS and Jimp.

Rendering pictures: will be done by 3rd party library npm package called Jimp. pictures will come in small size with the app itself as its assets.
