Reusable Modules: Build Modular Systems

Reusable modules build systems. Modular. Maintainable.

Here's the thing: Modules make systems maintainable. Build them.

Module Structure​

# modules/logging.sh
log_info() { ... }
log_error() { ... }

My take: Modules group related functions. Organize them.

Using Modules​

source modules/logging.sh
log_info "Message"

My take: Source modules. Use functions.

Common Patterns​

Module System​

# Load all modules
for module in modules/*.sh; do
    source "$module"
done

What's Next?​

Now that you understand modules, you can build systems. Or review Modular Scripting to reinforce.

Personal note: Modules seemed complex at first. Then I built them. Now I use them always. They're useful. Build them.
