  Hacker News clone using Remix and React2022 · github.com · ▲80

  Hi all, author here. This project was a pleasure to do, Remix has very good developer experience. But further than that it's actually a really good way to develop applications, it's a mix of old meets new where the paradigm encourages you to take advantage of web standards for data fetching (forms, links, a tags). And it turns out that it's actually an optimal way to develop simple or even complex web applications which can deploy in a number of runtime environments (including edge workers). So you can get an insanely fast website for users. Note that this project is not necessarily an…

  Crowd.dev – The open-source platform for community-led growth2022 · github.com · ▲24

  Hi everyone, after months of work we’re excited to show you crowd.dev - the open-source platform for community-led growth. We created crowd.dev with the belief that the future of business relies on thriving communities - particularly in the fast-growing open-source and developer space. Developers have increased buying power when it comes to the technologies their companies use, and the way to their hearts isn’t through paid ads or sales reps but through authentic community interactions. In other words, developer-focused companies (open-source, API, dev tools) need communities to grow. While…

  Talanoa▲341

  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…

  JS library to make your website instant▲426

  http://instantclick.io/ It seems the internet architecture won't bring us instant websites anytime soon. So here is a hack. I released this JS library last month (today is version 2.0 release, fixing v1.0's rough edges), it makes use of HTML5's pushState and preloading to make a website instant. It works like this: before clicking on a link, you'll hover over it. And there's a delay of 200-300 ms between these two events. InstantClick uses this delay to preload a page, when you click on a link it will display instantly in most case. (You can test on the website.) That's…

  I redesigned the Microsoft employee badge▲322

  For a while, I had this idea of redesigning Microsoft employee badges for a modern and neat look. So I spared a few hours this weekend. It’s over a year Microsoft has started to rebrand itself, starting from its logo to a brand new looking OS, from campus shuttles to direction signs on the cam
