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

@brainstack/crud

A TypeScript CRUD (Create, Read, Update, Delete) abstraction package that allows you to perform CRUD operations using different data sources.

Installation

Install the package using npm:

npm install @brainstack/crud

Usage

import { createCRUD, CRUDIntegration, CRUD } from '@brainstack/crud';

// Define CRUDIntegration implementation
class MyCRUDIntegration<T> implements CRUDIntegration<T> {
  // Implement CRUD methods here...
}

// Create CRUD instance
const myCRUD: CRUD<MyType> = createCRUD(new MyCRUDIntegration<MyType>());

// Perform CRUD operations
const newItem = await myCRUD.create({ id: '1', name: 'Item 1' });
const readItem = await myCRUD.read('1');
const updatedItem = await myCRUD.update('1', { id: '1', name: 'Updated Item' });
await myCRUD.delete('1');
const listItems = await myCRUD.list();
const searchResults = await myCRUD.search('term');
const filterResults = await myCRUD.filter({ key: 'value' });

API

createCRUD(integration: CRUDIntegration<T>): CRUD<T>

Creates a CRUD instance with the provided integration.

  • integration: An object implementing the CRUDIntegration interface.

CRUDIntegration<T>

An interface defining the integration methods for CRUD operations. Implement this interface to connect to your data source.

  • create(item: T): Promise<T>
  • read(id: string): Promise<T | undefined>
  • update(id: string, item: T): Promise<T | undefined>
  • delete(id: string): Promise<void>
  • list(options?: { page?: number; limit?: number }): Promise<T[]>
  • search(term: string): Promise<T[]>
  • filter(criterias: { [key: string]: any }): Promise<T[]>

Integration Examples

REST API Integration

import axios from 'axios';
import { CRUDIntegration } from '@brainstack/crud';

class RestAPIIntegration<T> implements CRUDIntegration<T> {
  constructor(private baseUrl: string) {}

  async create(item: T): Promise<T> {
    const response = await axios.post(this.baseUrl, item);
    return response.data;
  }

  // Implement other CRUD methods...
}

const restAPI = new RestAPIIntegration<MyType>('https://api.example.com/items');
const crud = createCRUD(restAPI);

Mock Integration

import { CRUDIntegration } from '@brainstack/crud';

class MockCRUDIntegration<T> implements CRUDIntegration<T> {
  private data: Record<string, T> = {};

  async create(item: T): Promise<T> {
    this.data[item.id] = item;
    return item;
  }

  async read(id: string): Promise<T | undefined> {
    return this.data[id];
  }

  // Implement other CRUD methods...
}

const mockIntegration = new MockCRUDIntegration<MyType>();
const crud = createCRUD(mockIntegration);
