qrcode VS exiftool-vendored.js

qrcode (https://github.com/soldair/node-qrcode)

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.

We’ll be using qrcode NPM package for generating a QR Code. It can be installed using npm i --save-dev @types/qrcode for TypeScript projects or npm install qrcode --save.

You can find more information about qrcode's options on its GitHub page.

This is a nodejs library for QR code. https://www.npmjs.com/package/qrcode#nodejs

Something like this should work: https://www.npmjs.com/package/qrcode

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):

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...
