Node.js – display the first 3 objects of json file

I’m trying to create an HTML template which takes in an array of card objects and uses the data contained within to generate a page to display the list of cards. Basically I have a json file filled with hundreds of cards (for the purpose of this post, I’ve only included a few) and I’m trying to figure out how to print out links for only the first 3 cards. If I were to run my server, my localhost:3000/cards page which is my cards.pug file, creates links for every single card in the json file.

Each link is made up of the card’s name and id, and I’m not quite sure how I would edit my server so that it would only return the first 3 cards instead of all of them. Any help or a push in the right direction would be appreciated!

Server.js:

const pug = require(“pug”);
const fs = require(“fs”);
const http = require(“http”);
const url = require(‘url’)

let cardData = require(“./cards.json”);
let cards = {};
cardData.forEach(card => {
cards[card.id] = card;
});

//Initialize server
const server = http.createServer(function(request, response) {
if (request.method === “GET”) {
if (request.url === “/cards”) {
response.statusCode = 200;
response.write(pug.renderFile(“./views/cards.pug”, { cards: cards }));
response.end();
}else if (request.url.startsWith(“/cards/”)) {
const paths = request.url.split(“/”);
const cardId = paths[2];
if (cards.hasOwnProperty(cardId)) {
const targetCard = cards[cardId];
response.statusCode = 200;
response.write(
pug.renderFile(“./views/card.pug”, { card: targetCard })
);
response.end();
return;
} else {
response.statusCode = 404;
response.end();
return;
}
}
} else {
response.statusCode = 404;
response.write(“Unknown resource.”);
response.end();
}
});

//Start server
server.listen(3000);
console.log(“Server listening at http://localhost:3000”);

cards.pug:

html
head
title Cards
body

div#main
h1 List of Cards:
each card in cards
a(href=”/cards/” + card.name) #{card.id}
br

card.pug:

html
head
title #{card.name}
body

div#main
h1 Name: #{card.name}, Cost: $#(card.cost)

My cards.pug page just shows a bunch of links that have the name and id of the card.
So for example, the first card appears as a link that says “Fallen Hero (AT_003)”
