Flintable – Fixable ESLint rules Playground

Hi community! I am glad to introduce to you my latest project! What? Flintable is a playground for experimenting lint rules, focusing on fixable layout and suggestions rules. I initially focused on ESLint, the most popular JavaScript linter. Flintable allows adding your code and regularly testing it with individual rules or custom configurations, composing your own configuration file. How? I developed Flintable using the PHP Laravel framework for the server side and the Vue framework linking them with Inertia JS, accompanied by Tailwind CSS for the client side. Laravel Horizon manages the…

Flintable – Fixable ESLint rules Playground launched on August 23, 2023 with 14 votes, #1,584 of 4,347 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.

In plain words

Flintable is a web-based playground for testing and experimenting with ESLint rules and configurations. Developers can paste code, apply individual linting rules or custom configurations, and see results in real time. The tool helps teams understand how different ESLint rules behave before implementing them across a codebase. Built with Laravel, Vue, and Inertia JS, it features a code editor and supports composing custom configuration files for testing.

    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…

  • Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
