Expose is a beautiful, open source, tunnel application that allows you to share your local websites with others via the internet.

Since you can host the server yourself, you have full control over the domains that your shared sites will be available at. You can extend expose with additional features and middleware classes on the server and client side, to make it suit your specific needs.

Alan Shreve closed ngrok’s source code years ago, and every now-and-again an open source alternative pops on the scene. Add Expose to the list. It’s written in PHP and has a nice shine on it. But which of these SSH tunneling tools is best in class?

I use EXPLAIN ANALYZE infrequently enough that the time I spend squinting at the results and then searching for help interpreting them often outweighs the benefit of the query altogether. Not anymore, baby! This nifty tool increases the readability of EXPLAIN ANALYZE by 1000%. And that’s science!

Go Binaries is an on-demand binary server, allowing non-Go users to quickly install tools written in Go without installing go itself, and removing the burden of cross-compiling and uploading dozens of binaries for every command-line you write.

Minimal CSS “frameworks” are on the rise. There are so many of them now that it’s hard to compare apples to apples. This’ll help.

This is a quick drop-in CSS switcher to allow for previewing some of the many minimal CSS-only frameworks that are available. See the demo or drop the switcher into your own page to see how different frameworks would look together with your content.

This project only includes minimal frameworks, in other words, boilerplate / classless frameworks that require no adjustment of the corresponding HTML and can be simply dropped into the project to provide a starting point for further design. No additional javascript, compiling, pre-processors, or fiddling with classes should be required for these to look good and be responsive.

lite is a lightweight text editor written mostly in Lua — it aims to provide something practical, pretty, small and fast, implemented as simply as possible; easy to modify and extend, or to use without doing either.

Google recently announced their Web Vitals initiative which seeks to condense and simplify what devs need to know to optimize our sites.

Linked is an accompanying (alpha-grade) Chrome extension that measures the 3 Core Web Vitals and displays your scores at the click of a button.

Addy Osmani has created an excellent resource for all developers interested in optimizing their web performance (which should be pretty much all of us).

You’ve probably heard of Puppeteer, which lets you control Chromium headlessly over the DevTools protocol. This repo shows you how to use Puppeteer to automate performance measurement, such as getting a performance trace for a page load:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  // Drag and drop this JSON file to the DevTools Performance panel!
  await page.tracing.start({path: 'profile.json'});
  await page.goto('https://pptr.dev');
  await page.tracing.stop();
  await browser.close();
})();

Which produces the results in the image below.

Delta provides language syntax-highlighting, within-line insertion/deletion detection, and restructured diff output for git on the command line. All the syntax-highlighting color themes that are available with bat are available with delta. Here’s what git show looks like when git is configured to use delta as its pager:

This is a very cool idea and the use case is described perfectly by the authors:

Does your designer cry every time you load their beautifully designed screen, and it is full of empty boxes because all the images have not loaded yet? Does your database engineer cry when you want to solve this by trying to cram little thumbnail images into your data to show as placeholders?

You give BlurHash an image and it gives you back a short string (20-30 chars) that represents the placeholder image. Store the string and send it along with the other data for the object and your client can decode the string into a placeholder image while the real image is loading over the network.

Lars Wikman:

I’ve been thinking a lot about inexperienced (junior, if you must) web developers and just how much there is to learn about programming in general but the web in particular. You often hear people say that you don’t need to know everything but you should have a solid foundation. Well, how do you establish a solid foundation and how do you know if you have one? How do you get introduced to all the relevant terminology and how do you find out what you haven’t learned yet?

To help with this, Lars created a self-evaluation checklist tool.

Jonathan Chang and Michael Deng share all the details of the systems required to deploy at Slack.

Deploys require a careful balance of speed and reliability. At Slack, we value quick iteration, fast feedback loops, and responsiveness to customer feedback. We also have hundreds of engineers who are trying to be as productive as possible. Keeping to these values while growing as a company means continual refinement of our deployment system.

Rclone acts like its source of influence, rsync, but instead syncs files and directories to many cloud storage providers. It runs on all the Linux/macOS/Windows flavors. You can even install with Homebrew on macOS.

brew install rclone

Based on what I read in the HN comments there are tons of users/uses for Rclone.

A fun way to discover interesting color combos. Whatch out for that undiagnosed light indigo.

Patrick DeVivo:

tickgit is a tool for software developers to do project management within their codebase. It searches code comments for markers indicating areas and files worth returning to (TODO, FIXME, etc). It can be used to proactively identify areas of technical debt, or handle day-to-day to-do items and checklists.

Free for public repos and open source.

A handy little web app for quickly finding the droids code you’re looking for.

grep.app searches code from over a half million public repositories on GitHub. We’re hoping to add more soon…

It searches for the exact string you enter, including any punctuation or other characters. You can also search by regular expression, using the RE2 syntax.

It includes a compiler, linter, formatter, bundler, testing framework and more. It aims to be a comprehensive tool for anything related to the processing of JavaScript source code.

Rome aims to be a replacement for many existing JavaScript tools. We will, however, offer integrations for components in other tools. For example, using the Rome compiler as a plugin for another bundler.

This comes out of Facebook’s React Native team. It’s MIT licensed and was started by Sebastian McKenzie, who also authored Babel and Yarn.

For macOS and Linux. Built with Tauri Studio.

This tool is surrounded by mountains of marketing speak, but it does seem like it offers a quick way to spin up different dev environments, which is cool. It has built-in recipes for WordPress, Drupal, LAMP, MEAN, and more. Here’s how you get started on Drupal 7, for example:

lando init \
  --source remote \
  --remote-url https://ftp.drupal.org/files/projects/drupal-7.59.tar.gz \
  --remote-options="--strip-components 1" \
  --recipe drupal7 --webroot . \
  --name hello-drupal7

You can use these out of the box or start with a base language and mix in the things you need from there. Kinda like Docker Compose? Yeah, kinda like Docker Compose:

You can think of Lando as both an abstraction layer and superset of Docker Compose as well as a Docker Compose utility.

This is a full-featured replacement for many of your shell’s built-ins.

No more waiting for your bundler to rebuild your site every time you hit save. Instead, every change is reflected in the browser instantly.

This relies on ESM (Mikeal gave a great rundown on the current state of things on a recent JS Party), so it’s not for everyone. The homepage has rundowns on who should use this, who should avoid it, and how to get started.

Brought to you by the fine folks at Pika.

Think of this like jq, but for people who love parentheses. 😀

cat test.json | jql '(elem "countries" (elem (keys) (elem "name")))'
[
  "Poland",
  "United States",
  "Germany"
]

Inspired by knative-inspect. Installable with the krew plugin manager.

SQLx is a modern SQL client built from the ground up for Rust, in Rust.

• Truly Asynchronous. Built from the ground-up using async-std using async streams for maximum concurrency.

• Type-safe SQL (if you want it) without DSLs. Use the query!() macro to check your SQL and bind parameters at compile time. (You can still use dynamic SQL queries if you like.)

• Pure Rust. The Postgres and MySQL/MariaDB drivers are written in pure Rust using zero unsafe code.

localdots combines Caddy and smallstep/certificates with automated configuration and hot reload.

• Generates SSL/TLS certificates automatically
• Reloads Caddy automatically with every change

This package is intended to give you more control over error handling via error wrapping, stack tracing, and output formatting. Basic error wrapping was added in Go 1.13, but it omitted user-friendly Wrap methods and built-in stack tracing. Other error packages provide some of the features found in eris but without flexible control over error output formatting. This package provides default string and JSON formatters with options to control things like separators and stack trace output. However, it also provides an option to write custom formatters via eris.Unpack.
