Spidex

npm version npm downloads Build Status Coverage Status

Spidex is a versatile web requester for Node.js and browsers, designed to simplify HTTP requests with a clean and intuitive API.

Features

  • Supports both Node.js and browser environments.
  • Handles GET, POST, PUT, DELETE and other methods.
  • Customizable request options including headers, timeouts, and charsets.
  • Built-in support for various character encodings.
  • Hessian v2 protocol support (Node.js only).
  • Event-based error handling.

Installation

Install Spidex using npm:

npm install spidex --save

Usage

Basic Request

const spidex = require('spidex');

spidex.get('https://api.example.com/data', (content, statusCode, responseHeaders) => {
  console.log('Response:', content);
  console.log('Status:', statusCode);
  console.log('Headers:', responseHeaders);
}).on('error', err => {
  console.error('Error:', err);
});

Request with Options

spidex.post('https://api.example.com/users', {
  data: JSON.stringify({ username: 'john_doe', email: 'john@example.com' }),
  header: { 'Content-Type': 'application/json' },
  charset: 'utf8',
  timeout: 5000
}, (content, statusCode, responseHeaders) => {
  console.log('User created:', content);
}).on('error', (err) => {
  console.error('Error creating user:', err);
});

Supported Basic HTTP Methods

Spidex supports the following HTTP methods:

  • spidex.get(url, [options], [callback])
  • spidex.post(url, [options], [callback])
  • spidex.put(url, [options], [callback])
  • spidex.delete(url, [options], [callback])

Each method returns an EventEmitter that emits an 'error' event if an error occurs.

Supported Other HTTP Methods

  • spidex.method(url, method, [options], [callback])

Request Options

The options object can include the following properties:

  • data: Request body (string, object, or Buffer)
  • header: Custom request headers
  • charset: Character encoding (e.g., 'utf8', 'gbk', 'binary', etc.)
  • timeout: Total request timeout in milliseconds
  • responseTimeout: Response timeout in milliseconds
  • requestTimeout: Request timeout in milliseconds

Parsing Cookies

Spidex provides a utility function to parse cookies from response headers:

const cookies = spidex.parseCookies(responseHeaders);
console.log('Parsed cookies:', cookies);

User Agent Management

You can get or set the default User-Agent string:

// Get the current User-Agent
const currentUA = spidex.getDefaultUserAgent();

// Set a custom User-Agent
spidex.setDefaultUserAgent('MyApp/1.0');

Hessian v2 Support (Node.js only)

Spidex supports Hessian v2 protocol for Node.js environments:

spidex.hessianV2('http://hessian.example.com/api', 'methodName', [arg1, arg2], (err, result) => {
  if (err) {
    console.error('Hessian request failed:', err);
    return;
  }
  console.log('Hessian result:', result);
});

TypeScript Support

Spidex includes TypeScript definitions. You can import and use it in TypeScript projects:

import * as spidex from 'spidex';

spidex.get('https://api.example.com/data', (content, statusCode, responseHeaders) => {
  console.log('Typed response:', content);
});

Error Handling

All Spidex methods return an EventEmitter that emits an 'error' event. You can handle errors by listening to this event:

spidex.get('https://api.example.com/data')
  .on('error', (err) => {
    console.error('Request failed:', err);
  });
