Show HN: ESInfer – Make JavaScript Type-Safe

Hello, folks. I'm Jiang, the author of ESInfer.<p>I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system.<p>To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript.<p>It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes.<p>It is still in the very early stage, which offers almost all ES5 features and a select set of ES6 features like array/object destructing. I'm working hard to bring all ES6+ features into it incrementally.<p>If you heavily use javascript/typescript and do NOT want to write the type annotation sh*ts anymore, give it a try :)

Show HN: America – Road Trip Simulator

APIs are a little like the open road—always waiting, full of opportunity, but hardly utilized. So here’s America, composed of several APIs that paint a vivid, real-time picture of a good old-fashioned road trip. Get local classifieds and photos. Tune into local radio stations. Talk wit other drivers. And more.<p>Exploring the country by car was an invaluable experience for me during my time in the states. I’ve since moved to Barcelona, and find myself missing the territory. This is my attempt at recreating the magic.

Show HN: Metlo (YC S21) – An Open Source API Security Tool

Metlo - An Open Source API Security Tool<p>Hey folks! Excited to share what we’ve been working on for the last couple months. Metlo is a self hosted, open source first API security platform that inventories, tests and protects your API endpoints:<p>- We inventory your endpoints by scanning API traffic and detecting all your endpoints along with the sensitive data they contain.<p>- We generate information your security team may find useful like Open API Specs and risk scores for each endpoint.<p>- After this we discover vulnerabilities like unauthenticated endpoints returning sensitive data or missing HSTS headers.<p>- Finally Metlo detects any anomalous behavior on sensitive endpoints in real time so you can detect 0-day attacks as they're happening.<p>We have a demo environment to play around with here <a href="http://demo.metlo.com/" rel="nofollow">http://demo.metlo.com/</a>. Also, Here's a demo video if you would like a quick walk through of the product :) <a href="https://www.loom.com/share/349c9e5f267741e9a0fcd2dfd1f9956f" rel="nofollow">https://www.loom.com/share/349c9e5f267741e9a0fcd2dfd1f9956f</a>

Show HN: Circumflex, browse HN in your terminal

Some two years ago, I found myself spending a lot of time in the terminal between learning vim and discovering new command line tools. I was surprised to see that the niche of HN clis was (relatively) small, and so I decided to write my own command line tool for browsing HN called `circumflex`(`clx`).<p>`clx` is written in Go using Bubble Tea[1]. You can read the comment section or the linked article in reader mode in the pager `less`.<p>Using `lesskey` to add custom keybindings, the replies can be collapsed and expanded in real-time (but not individual replies, only all replies at once). Behind the scenes I am appending invisible unicode characters to each line so that I can use the custom keybindings to filter them out. The same technique is used to allow for jumping between top-level comments.<p>I spent a lot of time thinking about syntax highlighting and finding relevant bits to highlight while also not going overboard with colors. The end result is highlighting of things I find useful for providing context in the comment section, like indicating parent poster and original poster, coloring references, coloring indentations as well as formatting YC startups.<p>Other quality of life features include adding submissions as favorites (it is stored as a pretty-printed json so you can check it into your vcs to allow for readable diffs). Submissions are marked as read and new comments are indicated with a bullet point.<p>[1] <a href="https://github.com/charmbracelet/bubbletea" rel="nofollow">https://github.com/charmbracelet/bubbletea</a>
