air VS entr

To enable live reloading in Go we will checkout the command tool, Air - Live reload for Go apps.

This is made possible thanks to the Air tool, which now comes with every project you create. The configuration is as follows:

At a recent job, we had slightly different containers for local dev; our backend containers (for a Go app) had Air [1] installed for live reloading, plus Delve [2] running inside the container for VS Code's debugger to connect to. We also had a frontend container for local dev, which didn't get deployed as a container, just as static files.

Air is an automatic reloading tool for Go applications. It keeps an eye on code changes and automatically restarts the application, making development more efficient.

Just to add to the list there is also https://github.com/cosmtrek/air

Do you use anything for live reloading? This is one aspect I miss when using gomponents compared to go templates, where I had a setup using Browsersync, which immediately refreshed whenever html/css/js changed. Now, since all HTML is within Go code, I have to recompile my go program to see changes, which takes up to ~5sec (I use https://github.com/cosmtrek/air for this).

entr ("Event Notify Test Runner"; GitHub), is a command-line tool written by Eric Radman that allows running arbitrary commands whenever files change.

I use something very similar on https://lunar.fyi and https://lowtechguys.com but I wouldn’t call this “simple” anymore.

They use Jinja templating, I prefer Slim (https://github.com/slim-template/slim#syntax-example) which has a more Pythonic syntax (there is plim [0] in Python for that)

I use Tailwind as well for terse styling and fast experimentation (allows me to write a darkMode-aware and responsive 100 line CSS in a single line with about 10 classes)

For interaction I can write CoffeeScript directly in the page [1] and have it compiled by plim.

I run a Caddy static server [2] and use Syncthing [3] to have every file save deployed instantly to my Hetzner server.

I use entr [4] and livereloadx [5] to rebuild the pages and do hot reload on file save. All the commands are managed in a simple Makefile [6]

You can already see how the footnotes take up a large chunk of this comment, this is not my idea of simple. Sure, the end result is readable static HTML and I never have to fight obscure React errors, but it’s a high effort setup for starters.

Simple for me would be: write markdown files for pages, a simple CSS for general styling (should be optional), click to deploy on my domain. Images should automatically be resized to multiple sizes and optimized, videos re-encoded for smaller filesize etc.

I have mostly implemented that for myself (https://notes.alinpanaitiu.com/How%20I%20write%20this%20blog...) but it feels fragile. I’d rather pay for a professional solution.

Try entr for fast reloading. Another one is hupper.
