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 🙏

Readme

PowerPages Tool Kit

This package provides utilities for managing and interacting with the DOM and making AJAX requests to a DataVerse API. It includes the API module for handling CRUD operations and the DOMNodeReference class for seamless DOM manipulations.

Installation

After installing

npm install powerpagestoolkit

You can then import into your JavaScript files as follows:

import {
  API,
  createDOMNodeReference,
  createMultipleDOMNodeReferences,
} from "powerpagestoolkit";

Modules

DOMNodereference

The DOMNodeReference module simplifies DOM element management. It provides functionalities for creating and interacting with DOM elements:

Usage

  • createDOMNodeReference(selector): Creates a DOMNodeReference instance for a single DOM element specified by a CSS selector or HTMLElement. Returns a DOMNodeReference instance.

  • createMultipleDOMNodeReferences(selector): Creates multiple DOMNodeReference instances for all elements matching the specified CSS selector. Returns an array of DOMNodeReference instances.

selector uses standard ED6 document.querySelector() syntax. For more information, read here

// single instance of DOMNodeReference
const node = await createDOMNodeReference("#my-element");

node.onceLoaded(() => {
  console.log("Element is loaded: ", node.element);
});

// to imitate 'querySelectorAll', and return an array of DOMNodeReferences
const nodeArray = await createMultipleDOMNodeReferences('div[class="row"]');

nodeArray.forEach((node) => {
    node.oneLoaded(() => {
        console.log("Element loaded: ", node.element")
    })
})
Available Properties

These properties are public and can be used in any custom logic/configurations

target: HTMLElement | string;
element: HTMLElement;
isLoaded: boolean;
value: any;
/**
 * If the element targeted is the main input for a yes/no radio control,
 * yesRadio and noRadio will be available as properties of 'this'
 */
yesRadio: DOMNodeReference;
noRadio: DOMNodeReference;
// and if 'this' is the instance of a yesRadio or noRadio
// checked will represent wether the radio has been checked or not
checked: boolean;
Methods

Here are the key methods you can use with a DOMNodeReference instance:


/********/
// VISIBILITY / ACCESSIBILITY

// Hides the associated DOM element.
hide()

// Shows the associated DOM element.
show()

/**
 * advanced visibility control in the case you need to apply
 * custom logic to the visibility of an element
 */
toggleVisibility(shouldShow: boolean | () => boolean)

/**
  * Configures conditional rendering for the target element
  * based on a condition and the visibility of one or more trigger elements.
  *
  * @param {(this: DOMNodeReference) => boolean} condition -
  * A function that returns a boolean to determine the visibility
  * of the target element. If `condition()` returns true, the
  * element is shown; otherwise, it is hidden.
  * @param {Array<DOMNodeReference>} dependencies - An array
  * of `DOMNodeReference` instances. Event listeners are
  * registered on each to toggle the visibility of the
  * target element based on the `condition` and the
  *  visibility of the target node.
  */
configureConditionalRendering(
  condition: (this: DOMNodeReference) => boolean,
  dependencies: Array<DOMNodeReference>
  )


    // EXAMPLE:
    const your_node = await createDOMNodeReference("#element_id")
    const other_node = await createDOMNodeReference(".element_class")

    your_node.configureConditionalRendering(() =>
        other_node.value == "3",
        /* your_node will only be
        visible when the value of other_node is "3"
        */
        [other_node]
        /* and we have to include any DOMNodeReferences used
        in the evaluation logic, so that changes to them can
        be watched and the condition evaluated again
        */
      );


/**
 * Sets up validation and requirement rules for the field.
 * This function dynamically updates the field's required status
 * and validates its input based on the specified conditions.
 *
 * @param {function(this: DOMNodeReference): boolean} isRequired
 * A function that determines whether the field should be required.
 * Return `true` if required, `false` to not be required.
 * @param {function(this: DOMNodeReference): boolean} isValid
 * A function that checks if the field's input is valid.
 * Return `true` if validation satisfied, `false` if not.
 * @param {string} fieldDisplayName - The name of the field, used
 * in error messages if validation fails.
 * @param {Array<DOMNodeReference>} [dependencies]
 * Other fields that this field’s requirement depends on. When
 * these Nodes or their values change, the required status
 * of this field is re-evaluated. Make sure any DOMNodeReference
 * used in `isRequired` or `isValid` is included in this array.
 */
configureValidationAndRequirements(
  isRequired: (this: this) => boolean,
  isValid: (this: this) => boolean,
  fieldDisplayName: string,
  dependencies: Array<DOMNodeReference>
)

    // EXAMPLE:
    const your_node = await createDOMNodeReference("#element_id")
    const other_node = await createDOMNodeReference(".element_class")

    your_node.configureValidationAndRequirements(
        () => other_node.yesRadio.checked,
        /* if 'yes' is checked for this other node,
          this function will evaluate to true,
          meaning that 'your_node' will be required */

        function () {
          /* important to use standard 'function' declaration,
            instead of arrow function when needing to
            access 'this' (the instance of 'your_node') */

          if (other_node.yesRadio.checked) {
            // when other_node radio is checked 'yes'
            return this.value; // this is only 'valid' if it has a value
          } else return true;
        },
        "Your Field Name",
        [other_node]
        /* since our conditions depend on
          'other_node' it must be included in the dependency
          array so that the requirement conditions can be
          re-evaluated when the value of 'other_node' changes */
      );


/* sets the elements 'disabled' to true - useful for inputs
that need to be enabled/disabled conditionally */

API

The API module provides functions for creating and retrieving records from a DataVerse. It includes the following methods:

  • createRecord(schema): Creates a new record in the DataVerse using the provided schema instance. Returns a Promise that resolves with the record ID or rejects with an error.

  • getRecord(tableSetName, recordID, selectColumns): Retrieves a specific record from the DataVerse. Returns a Promise that resolves with the retrieved record or rejects with an error.

  • getMultiple(tableSetName, queryParameters): Retrieves multiple records from the DataVerse based on specified query parameters. Returns a Promise that resolves with the list of retrieved records or rejects with an error.

Usage

1. Creating a Record

To create a new record in the DataVerse, you can use the createRecord method. This method takes an instance of a schema class containing the data for the record.

// Assuming you have a schema class defined
const schema = new YourSchemaClass({
  name: "Sample Record",
  description: "This is a sample record for demonstration.",
});

API.createRecord(schema)
  .then((recordId) => {
    console.log("Record created successfully with ID:", recordId);
  })
  .catch((error) => {
    console.error("Error creating record:", error);
  });
2. Getting a Single Record

To retrieve a specific record from the DataVerse, use the getRecord method. You need to provide the table set name and the record ID.

const tableSetName = "accounts"; // The DataVerse table set name
const recordID = "your-record-id"; // The GUID of the record to retrieve

API.getRecord(tableSetName, recordID)
  .then((record) => {
    console.log("Retrieved record:", record);
  })
  .catch((error) => {
    console.error("Error retrieving record:", error);
  });
3. Getting Multiple Records

If you need to retrieve multiple records with specific query parameters, you can use the getMultiple method. This method accepts the table set name and optional query parameters for filtering.

const tableSetName = "contacts"; // The DataVerse table set name
const queryParameters =
  "$filter=firstName eq 'John'&$select=firstName,lastName"; // OData query parameters

API.getMultiple(tableSetName, queryParameters)
  .then((records) => {
    console.log("Retrieved records:", records);
  })
  .catch((error) => {
    console.error("Error retrieving records:", error);
  });
Example Schema Class

Here's a simple example of a schema class that you might use with the createRecord method:

class YourSchemaClass {
  constructor(tableSetName, data) {
    this.setName = tableSetName;
    this.data = data;
  }

  value() {
    return JSON.stringify(this.data); // Convert data to JSON format for the API
  }
}
