@sitchco/project-scanner

A utility class for scanning a Sitchco WordPress project to discover modules, asset entry points, and other key directories based on established conventions.

Overview

This package provides a programmatic interface for navigating the project structure. It is the foundational discovery tool used by other build scripts like @sitchco/module-builder and @sitchco/formatter to get a reliable list of files and paths to operate on.

It is built on a "convention over configuration" philosophy, meaning it understands the project's layout without needing complex configuration.

Core Directory Conventions

The scanner's logic is based on the following directory structure:

• Module Directory: Any direct subdirectory located inside the top-level modules/ folder is considered a module.
• Asset Entry Points: Within each module, the scanner looks for buildable assets (.js, .mjs, .jsx, .scss, .css) in these specific locations:
  • The module's root
  • assets/scripts/
  • assets/styles/
  • The root of any block within blocks/
  • The assets/ directory of any block within blocks/
• WordPress Web Root: The scanner can traverse up the directory tree to locate the folder that contains wp-content, identifying it as the web root.

Programmatic Usage (API)

The main export is the ProjectScanner class.

new ProjectScanner(options?)

Creates a new scanner instance.

import ProjectScanner from '@sitchco/project-scanner';

// Create a scanner instance starting from the current working directory
const scanner = new ProjectScanner();

// Or, create an instance with a specific project root
const scannerWithCustomRoot = new ProjectScanner({
    projectRoot: '/path/to/sitchco-core',
});

Options:

• projectRoot (string): The absolute path to the project's root directory. Defaults to process.cwd().
• ignorePatterns (string[]): An array of glob patterns to ignore during scans.

Public Methods

All methods return a Promise.

• .getModuleDirs(): Promise<string[]> Returns an array of absolute paths to all discovered module directories (e.g., ['.../sitchco-core/modules/Demo']).

• .getEntrypoints(): Promise<string[]> Returns a flattened array of absolute paths to all discoverable asset entry points across all modules.

• .getWebRoot(): Promise<string> Scans upwards from the project root to find and return the absolute path to the WordPress web root (the directory containing wp-content).

• .findAllSourceFiles(extensions: string[]): Promise<string[]> Finds all files with the given extensions (e.g., ['.php', '.svg']) within the entire project, respecting ignore patterns.

• .findModuleSourceFiles(extensions: string[]): Promise<string[]> Similar to findAllSourceFiles, but scopes the search to only the discovered module directories.

• .cleanBuildArtifacts(): Promise<void> Finds and removes the build artifact directory (dist/) within the project.

• .clearCache(): void Clears the internal cache for module directories, entry points, and the web root, forcing a fresh scan on the next method call.
