securely request from browsers

Install

To use @push.rocks/webrequest in your project, install it using npm or yarn:

npm install @push.rocks/webrequest --save
# or with yarn
yarn add @push.rocks/webrequest

This package is designed to be used in an environment where ECMAScript Modules (ESM) and TypeScript are supported.

Usage

@push.rocks/webrequest is a powerful module designed to simplify making web requests securely from browsers. It leverages modern JavaScript features and TypeScript for a type-safe development experience. Below are comprehensive examples demonstrating how to utilize the module effectively:

Setting Up

First, import WebRequest from the module:

import { WebRequest } from '@push.rocks/webrequest';

Create an instance of WebRequest. You can optionally pass configuration options:

const webRequest = new WebRequest({
  logging: true // Optional: enables logging, defaults to true
});

Making GET Requests

To fetch JSON data:

// Fetch JSON data using GET request
async function fetchJsonData() {
  const url = 'https://api.example.com/data';
  try {
    const jsonData = await webRequest.getJson(url);
    console.log(jsonData);
  } catch (error) {
    console.error(error);
  }
}

fetchJsonData();

POST, PUT, and DELETE Requests

Similarly, you can make POST, PUT, and DELETE requests to send or manipulate data:

// Example POST request to submit JSON data
async function postJsonData() {
  const url = 'https://api.example.com/submit';
  const data = { key: 'value' };

  try {
    const result = await webRequest.postJson(url, data);
    console.log(result);
  } catch (error) {
    console.error(error);
  }
}

postJsonData();

// PUT and DELETE can be similarly used

Using Caches

The library provides mechanisms to cache responses, which is useful for reducing network load and improving performance. Here’s how to fetch data with caching:

// Fetch with caching enabled
async function fetchDataWithCache() {
  const url = 'https://api.example.com/data';
  try {
    // The second parameter enables caching
    const jsonData = await webRequest.getJson(url, true);
    console.log(jsonData);
  } catch (error) {
    console.error(error);
  }
}

fetchDataWithCache();

Handling Multiple Endpoints

@push.rocks/webrequest supports querying multiple endpoints with fallbacks to handle the situation where some endpoints may fail or be unavailable:

// Attempt to request from multiple endpoints
async function requestFromMultipleEndpoints() {
  const endpoints = [
    'https://api.primary-example.com/data',
    'https://api.backup-example.com/data'
  ];
  try {
    const response = await webRequest.requestMultiEndpoint(endpoints, {
      method: 'GET'
    });
    const data = await response.json();
    console.log(data);
  } catch (error) {
    console.error('Failed to retrieve data from any endpoint', error);
  }
}

requestFromMultipleEndpoints();

Advanced Usage

For advanced scenarios, you can directly use the request method to fully customize the request options including headers, request method, and body (for POST/PUT requests):

// Custom request with timeout
async function customRequest() {
  const url = 'https://api.example.com/advanced';
  try {
    const response = await webRequest.request(url, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ custom: 'data' }),
      timeoutMs: 10000 // Timeout in milliseconds
    });
    if (response.ok) {
      const result = await response.json();
      console.log(result);
    } else {
      console.error('Response error:', response.status);
    }
  } catch (error) {
    console.error('Request failed:', error);
  }
}

customRequest();

Conclusion

@push.rocks/webrequest offers a streamlined, secure way to handle web requests from browsers, supporting various HTTP methods, response caching, and requests to multiple endpoints with fault tolerance. Its TypeScript integration ensures type safety and enhances developer productivity by enabling IntelliSense in supported IDEs.
