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 🙏

React Observable Network Helper

Problem: In React applications, managing state for each network request can become repetitive and inefficient. For every single network request, the developer must create a new state to track loading, success, or failure, leading to redundant code. This repetitive process complicates the application as the number of requests grows, making it harder to maintain and scale.

Challange: Find efficient way to manage state for a network requests without have a redundant code to manage the state.

Proposed Solution: Introducing a React Observable Network Helper – a simple approach to manage network requests in React. This helper listens and emits state changes (loading, success, failure) for each network request, eliminating the need to create redundant states every time. By centralizing state management for network requests, this solution simplifies the network request code and reduces repetition.

Usage

Importing Package

import {
  HttpMethod,
  RequestFactory,
  useObservableHttpClient,
} from "react-observable-network-helper";

Creating Request

1. Create Axios Config

import { AxiosRequestConfig } from "axios";

export const axiosConfig: AxiosRequestConfig = {
  baseURL: "https://example.com",
};

2. Create Model and Mapper

export type PostModel = {
  userId: number;
  id: number;
  title: string;
  body: string;
};

export const mapToPostModel = (item: any): PostModel[] =>
  item.map((item: any) => ({
    userId: item.userId,
    id: item.id,
    title: item.title,
    body: item.body,
  }));

3. Create RequestFactory

const requestGetPost = RequestFactory<PostModel[]>({
  url: "/posts",
  mapper: (data) => mapToPostModel(data),
  httpMethod: HttpMethod.GET,
  config: axiosConfig,
  onErrorAction: (err) => {
    console.error(err);
  },
});

Using Request in React Component

const postRequest = useObservableHttpClient(requestGetPost);

Example Component

Here's a simple example of how to use the reqyests in a React component:

function App() {
  const postRequest = useObservableHttpClient(requestGetPost);

  return (
    <>
      <div>
        <button onClick={() => postRequest.fetchData()}>fetch api post</button>
      </div>

      <div>
        {postRequest.loading  && <div>loading...</div>}
        {postRequest.error  && <div>{postRequest.errorResponse?.message</div>}
        {postRequest.success && postRequest.data && postRequest.data.map((item) => (
          <div key={item.id}>
            <h3>{item.title}</h3>
            <p>{item.body}</p>
          </div>
        ))}
      </div>
    </>
  );
}
