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 🙏

Requirements

This package relies on the angular material library to render its components.

It also uses fontawesome-icons in some components.

Usage

ChangeSetService

To start using the change sets component you first need to provide a change set service.

This service provides default options for the component and handles logic like receiving change sets or rolling back.

import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { BaseChangeSetService, ChangeSet } from 'ngx-material-change-sets';

@Injectable({ providedIn: 'root' })
export class ChangeSetService extends BaseChangeSetService {
    constructor(http: HttpClient) {
        super(http);
    }

    override async openCreatedBy(changeSet: ChangeSet): Promise<void> {
        // What to do when a user clicks on the "createdBy" link.
    }
}

If you want to change some of the default options you can overwrite their respective property on the service class.

You need to provide the service in your app.module.ts:

import { NGX_CHANGE_SET_SERVICE } from 'ngx-material-change-sets';
//...
providers: [
    {
        provide: NGX_CHANGE_SET_SERVICE,
        useExisting: ChangeSetService
    }
],
//...

Use the component

First add the component to the imports array in your module or standalone component:

import { ChangeSetsComponent } from 'ngx-material-change-sets';
//...
imports: [
    //...
    ChangeSetsComponent
    //...
]
//...

Wherever you want to display the change history simply add:

<ngx-mat-change-sets [entity]="entity" [changeSetsApiBaseUrl]="testBaseUrl">
</ngx-mat-change-sets>

Where entity needs to extent from ChangeSetEntity or ChangeSetSoftDeleteEntity. The base url is a string that will be provided to the rollback and reset methods of the change set service. That way it can handle multiple different entity types.
