Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Magnolia CLI Plugin Helper Repository

A Magnolia CLI helper package that centralizes shared functions and configurations for developing plugins efficiently

Installation

To use this helper library in your Magnolia CLI plugins:

npm install "@magnolia/cli-helper"

Then, import the necessary utilities in your plugin code:

import { validateName } from '@magnolia/cli-helper/general-utils';
import { initI18n } from '@magnolia/cli-helper/i18n';

Modules

config.ts

The config.ts file in this repository provides utilities for managing and modifying the mgnl.config.js configuration file, which is essential for various operations in Magnolia CLI plugins. The file handles reading, writing, and updating shared and plugin-specific properties in the configuration file while offering logging capabilities to track changes.

Exported Functions Overview

  1. modifyConfig(args: ConfigUpdates, pluginName: string, logger: Logger): Promise<void>

    • Modifies the mgnl.config.js file based on the provided shared and plugin properties.
    • Parameters:
      • args: An object containing sharedProps (global properties) and pluginProps (plugin-specific properties) to be added or modified.
      • pluginName: The name of the plugin props for modification.
      • logger: A Winston Logger instance for logging.
    • Returns: A Promise that resolves when the configuration is successfully modified.
  2. getRelativePathToMGNLConfig(p: string): string

    • Converts an absolute path to a relative path with respect to the mgnl.config.js file.
    • Parameters:
      • p: The absolute path to be converted.
    • Returns: The relative path as a string.
  3. getMgnlConfig(logger: Logger): Promise<any>

    • Loads and returns the mgnl.config.js file as a JavaScript object.
    • Parameters:
      • logger: A Winston Logger instance for logging.
    • Returns: A Promise that resolves to the contents of the mgnl.config.js as an object. If the file doesn't exist or cannot be imported, an empty object is returned.
  4. readMgnlConfigFile(logger: Logger): string

    • Reads and returns the contents of the mgnl.config.js file.
    • Parameters:
      • logger: A Winston Logger instance for logging.
    • Returns: The contents of the mgnl.config.js file as a string. If the file does not exist, an empty string is returned.

general-utils.ts

The general-utils.ts file contains several helper functions for common tasks such as path manipulation, validation, and checking command-line flags. These functions are used to streamline plugin development by providing reusable utilities.

prototype.ts

The prototype.ts file manages the resolution and validation of prototypes used within Magnolia CLI plugins. Prototypes define templates or configurations that are utilized when generating blocks, components, or other plugin-based elements.
