What is request-promise-core?

The request-promise-core package is a foundational library for making HTTP requests in Node.js. It is designed to be a lightweight and flexible core for building HTTP request libraries with promise support. It provides the essential functionality for making HTTP requests and handling responses, and it can be extended or used as a base for more complex request libraries.

What are request-promise-core's main functionalities?

Basic HTTP Request

This feature allows you to make a basic HTTP GET request to a specified URI and handle the response using promises. The example demonstrates how to fetch a post from a placeholder API and log the response.

const request = require('request-promise-core');
const options = {
  method: 'GET',
  uri: 'https://jsonplaceholder.typicode.com/posts/1',
  json: true
};
request(options)
  .then(response => {
    console.log(response);
  })
  .catch(err => {
    console.error(err);
  });

Custom Request Options

This feature allows you to customize the HTTP request by specifying various options such as method, URI, and request body. The example demonstrates how to make a POST request to create a new post on a placeholder API.

const request = require('request-promise-core');
const options = {
  method: 'POST',
  uri: 'https://jsonplaceholder.typicode.com/posts',
  body: {
    title: 'foo',
    body: 'bar',
    userId: 1
  },
  json: true
};
request(options)
  .then(response => {
    console.log(response);
  })
  .catch(err => {
    console.error(err);
  });

Handling Errors

This feature demonstrates how to handle errors that occur during an HTTP request. The example shows how to catch and log errors when making a request to an invalid endpoint.

const request = require('request-promise-core');
const options = {
  method: 'GET',
  uri: 'https://jsonplaceholder.typicode.com/invalid-endpoint',
  json: true
};
request(options)
  .then(response => {
    console.log(response);
  })
  .catch(err => {
    console.error('Request failed:', err.message);
  });
