SignalQuery

SignalQuery is a lightweight and efficient query library for managing asynchronous data fetching and state management in JavaScript applications. It provides a simple yet powerful API for making HTTP requests and managing the resulting data using a reactive programming model.

Features

• Reactive State Management: Utilizes a custom Signal class for reactive state updates.
• Efficient HTTP Requests: Supports GET, POST, PUT, and DELETE methods.
• Caching: Implements caching for GET requests to reduce network overhead.
• Tag-Based Invalidation: Allows for intelligent cache invalidation using tags.
• TypeScript Support: Built with TypeScript for enhanced type safety and developer experience.
• Configurable: Easily customizable with options for base URL, headers, and timeout.

Installation

You can install SignalQuery using npm:

npm install signal-query

Usage

Basic Setup

First, create an instance of SignalQuery:

import { SignalQuery } from 'signal-query';

const query = new SignalQuery();

Making a GET Request

To make a GET request, use the query.get method:

const result = query.get({ url: '/api/data', params: { id: 1 } });

// Access the result properties
console.log('Loading:', result.isLoading.value);
console.log('Data:', result.data.value);
console.log('Error:', result.error.value);
console.log('Success:', result.isSuccess.value);
console.log('Error occurred:', result.isError.value);

// You can also create an effect to react to changes
createEffect(() => {
  if (result.isLoading.value) {
    console.log('Loading data...');
  } else if (result.isError.value) {
    console.log('Error:', result.error.value);
  } else if (result.isSuccess.value) {
    console.log('Data loaded:', result.data.value);
  }
});

Making a POST Request

To make a POST request, use the query.post method:

const result = query.post({ url: '/api/data', data: { name: 'John', age: 30 } });
