Zaplib – Speed up your webapp with Rust+Wasm

In plain words

Zaplib is a development tool that enables developers to build faster web applications by combining Rust and WebAssembly. It provides a framework for integrating Rust-compiled code into web projects to improve performance-critical components. The tool is designed for developers seeking to optimize webapp speed without completely rewriting their applications in Rust.

From the sources

Zaplib is an open-source library for speeding up web applications using Rust and WebAssembly. It lets you write high-performance code in Rust, alongside your existing JavaScript code. The goal of Zaplib is to make it easy to build performance-intensive applications in the browser. While it is possible to make JavaScript run fast, over time it may become hard to manage lots of optimizations. In Rust you tend to need way fewer optimizations to get high levels of performance, so you can focus on actually building stuff. Zaplib is designed to be incrementally adoptable . Start by porting over a single function you know is slow. Then port over an entire UI component, leaving the rest of your app…from zaplib.com

  Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell)…

  "Game" is a stretch, but I put together this repo containing a pure Rust app which uses SDL2 and compiles to WASM (and can be run in a browser). Older resources were a bit out of date and a bit too verbose for my purposes, so here's a minimal working example.

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Warp, a Rust-based terminal▲946

  Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
