Module Manager

The Module_Manager class provides a feature flag system for the Terra Framework. It lets you enable or disable optional framework features (like Grammar checking, Lighthouse monitoring, or the Schema Builder) on a per-project basis.

---

How It Works

The Module Manager reads a configuration that defines which optional features are active. Framework code checks Module_Manager::is_active('feature_name') before initializing optional classes.

<?php
// Inside functions.php, the Core class checks before instantiating optional modules:
if (Module_Manager::is_active('grammar')) {
    new Grammar($config);
}

if (Module_Manager::is_active('lighthouse')) {
    new TerraLighthouse($config);
}

Checking If a Module Is Active

Use the static method anywhere in your code:

<?php
if (Module_Manager::is_active('schema_builder')) {
    // Schema builder is enabled for this project
}

Common Modules

Module Key	Feature
grammar	Grammar and spelling checker (uses OpenAI)
lighthouse	Lighthouse performance monitoring
schema_builder	JSON-LD schema builder
csv_import	CSV import functionality
google_search_console	GSC integration
url_health_check	URL health monitoring

Note

Most projects only need a subset of these features. The Module Manager keeps unused features from loading, reducing overhead and admin clutter.
