Thanks XdekHckr! Do you have a particular use-case in mind?

I've now made improvements (to be released shortly) that will improve performance by

- Writer: 100 characters - 20 ops/sec, 1k characters - 11 op/sec - Reader: 100 characters - 15 ops/sec, 1k characters - 6 ops/sec

That's a 233%-1,100% increase in write speed, and a 50%-100% increase in read speed.

I'm also adding support for export to both canvas and GIF, as well as an estimated package bundle decrease of more than 300%.

I definitely will at some point. I haven't seen an attempt at a standard here. For now, I'd like to solidify the current libraries and prototype them with real users. Based on what I learn from there, and ISO proposal could be in the future. :)

Nice! I had seen these in Netflix or some TV app for a streaming service that allows you to authenticate using an animated QR code. I had the idea for Flipbook probably a decade ago but never did anything about it until now. I haven't seen another OSS project that does this so figured I'd give it a shot.

I'm in the early days of measuring performance, and it should improve dramatically with using a lower-level port, like in Rust. To me, that library is the long-term key to adoption as it allows the library to be embedded within native camera applications.

For the current Typescript version, I'm getting the following on Node 20 with my M1 Max MBP (64g RAM):

- Writer: 100 characters - 6 ops/sec, 1k characters - 1 op/sec - Reader: 100 characters - 10 ops/sec, 1k characters - 3 ops/sec

Again, those are preliminary and entire Node-based figures on a fairly-recent MBP. I'd expect significant performance improvements with both a Rust port as well as running the existing Typescript library through the Bun runtime.

That's absolutely correct. The good news is that Flipbook is intended to be more of a standard than a solution. The solution (the writer/reader libraries) are more intended as a specific implementation of a standard that could easily be adapted into native and non-native camera and scanning apps.

So yeah - your point is completely valid, but adoption has to start somewhere. Thanks for checking out the project!

Flipbook is a superset of QR codes that allows for infinitely sized payloads. Download apps, rich-text, and more without the need for an internet connection.
