watchman VS reflex

postCreateCommand This section permit to execute a command after the build of the container. I've used this command to execute a script to install Expo and other dependencies like watchman

Facebook open source product: https://github.com/facebook/watchman to get notified when configuration, file or other change

Facebook Meta's Watchman Service looks very useful for watching for changes in files and directories to kick off automation. Still, there seem to be a bunch of gotchas with it that only come to light after trying to mess with it. The docs seem lacking, the Python library needs to be updated, and even the installation on non-Ubuntu or Red Hat distros requires a rebuild, which has been somewhat problematic given the build tools. Also, no official Docker container.

Not to be confused with Facebook’s file watch daemon, which does the same sort of thing but is more complicated. There’s a bunch of tools that integrate Facebook’s watchman for more efficient change tracking.

Neat. I've used reflex in the past for this.

entr is written in C, watchexec is written in Rust.

There's another one that I've used that is written in go: https://github.com/cespare/reflex

I am inclined to use watchexec next time I need one.

rerun your go program when you change a file https://github.com/cespare/reflex

There are tools like https://github.com/cespare/reflex that run a command when specific files are changing. You could use it to run go test whenever one of your files changes, so the changes would be reflected instantly in the terminal.

We'll be using Reflex as part of our development workflow. If you're not familiar, Refelx provides live reload when developing.
