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 🙏

PERA-TRTA

Simple model/collection package

Version Downloads/week License dragol

PERA-TRTA is a simple package that provides basic functionalities for your models and collections.

All you gonna need to do is to extend your custom models and collections with Model and Collection, and you ready to go.

Some of the functionalities that package provide are:

  • both Model and Collection classes are heavily based on Typescript generics so IntelliSense support is given for using any of the methods implemented, see the images: img1 img2 img3
  • CLI support
  • get model property by key
  • update some properties of the model
  • update only one model property
  • store models in the collection
  • sort collection items
  • find particular item/items
  • map collection items ...

Here is the link for documentation pages.

####CLI support:

Instead of manually creating all necessary files, you can use CLI command pt.

pt -a Person 
// pt --all Person will work 
// pt --all=Person will work as well

Creates person model, interface and collection files (by appropriate template), each file has suffix -model, -interface, -collection respectively.

pt -i IPerson -m Person -c PersonCollection
// pt --interface IPerson --model Person --collection PersonCollection will work
// pt --interface=IPerson --model=Person --collection=PersonCollection will work as well

Creates IPerson, Person and PersonCollection files.

####Usage example:

category-props.ts

export interface ICategoryProps {
	id: number;
	name: string;
}

category-model.ts

import { ICategoryProps } from './category-props';
import { Model } from 'pera-trta';

export class CategoryModel extends Model<ICategoryProps> {}

category-collection.ts

import { CategoryModel } from './category-model';
import { ICategoryProps } from './category-props';
import { Collection } from 'pera-trta';

export class CategoryCollection extends Collection<CategoryModel, ICategoryProps> {}

index.ts

import { CategoryModel } from './category-model';
import { CategoryCollection } from './category-collection';

const cc = new CategoryCollection();
const c1 = new CategoryModel({ id: 1, name: 'pera' });
const c2 = new CategoryModel({ id: 2, name: 'trta' });
const c3 = new CategoryModel({ id: 3, name: 'pera' });

// add to collection
cc.add(c1);
cc.add([ c2, c3 ]);

// get all items from collection
console.log(cc.getAll());

// get items count
console.log(cc.getCount);

// map all collection items
cc.map((el: CategoryModel) => {
	return el.setByKey('name', el.get('name').toUpperCase());
});
console.log(cc.getAll());

// sort
cc.sortBy('id', 'desc');
console.log(cc.getAll());

// find
console.log(cc.findByKeyValue('name', 'PERA'));

// Remove - removes only first occurrence
cc.remove(c2, 'id');
console.log(cc.getAll());

cc.removeAllByKeyValue('name', 'PERA');
console.log(cc.getAll());
