NewsNode

A client library/wrapper around the Hacker News API written for Node.js with object mappings and TypeScript definitions. It should support anything that runs on the Node.js platform.

Bindings and models are designed to be as close as possible to the official API, while providing more predictability in terms of object properties.

Usage

Getting Started

Install the package using either npm or yarn, saving it to your project.

npm install newsnode --save

And then import the module into your project like so.

// With ES2015/ES6
import NewsNode from "newsnode";
// With CommonJS
const NewsNode = require("newsnode");

All requests made by this package will be done asynchronously, so you should use either Promise.then() or async and await to wait for the response to be returned.

Retreiving feed data

All methods below return an array of objects with the shape of the item type they're representing. You can find more by referring to types.ts and the official API docs.

// Get all types of stories by ranking (up to 500)
NewsNode.feeds.getNewStories()
NewsNode.feeds.getTopStories()
NewsNode.feeds.getBestStories()

// Get the latest stories by type (up to 200)
NewsNode.feeds.getAskStories()
NewsNode.feeds.getJobStories()
NewsNode.feeds.getShowStories()

// Get only 10 items
NewsNode.feeds.getShowStories(10);

// Get only 10 items after item id 20619715
NewsNode.feeds.getShowStories(10, 20619715);

You can also get the latest item by calling getMaxItem(), which is a binding to the /maxitem.json route. This only returns a single item.

// Get single newest item
NewsNode.feeds.getMaxItem()

Retreiving individual items

Functions found under the items property allow you to get indvidual items by ID.

// Types of posts
NewsNode.items.getStory(20619715)
NewsNode.items.getAsk(20619715);
NewsNode.items.getJob(20619715)

// Polls
NewsNode.items.getPoll(20619715)
NewsNode.items.getPollOption(20619715)

// Comments
NewsNode.items.getComment(20619715)

// Get comment responses
const story = await NewsNode.items.getStory(20619715);
const comments = await story.getDescendants();
// You can get subcomments by calling getDescendants() on comments[0..n], 
// which are elements of type HNComment, and therefore also implement the 
// getDescendants() method

Error handling

Request errors will be propogated to Promise.catch() and the catch block under a try block in an async/await function.
