Build a job board that displays the latest job postings fetched from the Hacker News API, with each posting displaying the job title, poster, and date posted.
Requirements
- The page should show 6 jobs on initial load with a button to load more postings.
- Clicking on the "Load more" button will load the next page of 6 postings. The button does not appear if there aren't any more postings to load.
- If there's a url field returned for the job details, make the job title a link that opens the job details page in a new window when clicked.
- The timestamp can be formatted in any way you like.
- Hacker News has a public API to fetch jobs by Y Combinator companies:
Fetches a list of job posting IDs.
- URL: https://hacker-news.firebaseio.com/v0/jobstories.json
- HTTP Method: GET
- Content Type: json
Job Details
-
Fetches job posting details given its ID.
-
HTTP Method: GET Content Type: json
The focus of this question is on functionality and not on styling, but feel free to beautify the page. To improve the user experience and avoid overfetching, you may want to limit the number of job details fetched to the number of jobs visible on the page.

create simple Form with fields username,email,mobile,password and a save button
-
save button will show data on UI in the table form.
-
while clicking on save button trigger post request through axios to save data inside mysql database
-
firstly we have to configure mysql with project and start server
-
Then post data and check on mysql workbench whether data save or not
-
server code :
const express = require("express"); const bodyParser = require("body-parser"); const mysql = require("mysql"); const cors = require("cors"); const app = express(); const port = 3000; app.use(cors()); app.use(bodyParser.json()); const connection = mysql.createConnection({ host: "localhost", user: "root", password: "rootlucky", database: "registration", }); // Connect to MySQL connection.connect((err) => { if (err) { console.error("Error connecting to MySQL:", err); return; } console.log("Connected to MySQL database"); }); // POST endpoint for user registration app.post("/userReg", (req, res) => { const { username, email, mobile, password } = req.body; const sql = "INSERT INTO TestUser2 (username, email, mobile, password) VALUES (?,?,?,?)"; const values = [username, email, mobile, password]; connection.query(sql, values, (err, result) => { if (err) { console.error("Error executing SQL query:", err); res.status(500).json({ message: "Registration failed" }); return; } console.log("User registered successfully"); res.status(200).json({ message: "User registered successfully" }); }); }); // Start the server app.listen(port, () => { console.log(`Server is running on port ${port}`); }); -
on save button this function runs that save the data and post data into mysql table
const handleClick = async () => { setRegisteredUsers([...registeredUsers, formData]); setFormData({ username: "", email: "", mobile: "", password: "" }); try { const response = await axios.post( "http://localhost:3000/userReg", formData ); console.log(response.data); // Assuming server sends back success message // You can handle success message here } catch (error) { console.error("Error:", error.message); // Handle error here } };

Now Move to Backend Part:
-
process: this object provides information about, and control over, the current Node.js process.
-
process.argv: returns an array containing the command-line arguments passed when the node.js process was launched.
-
requiring files
-
require() a build-in function to include external modules that exist in seperate files. module.exports a special object
-
installing packages
-
node_modules: The node_modules folder contains every installed dependency for your project.
-
package-lock.json: It records the exact version of every installed dependency, including its sub-dependencies and their version
-
package.json the package.json file contains descriptive and functional meta data about a project such as a name,version and dependencies
-
npm init
-
require vs import
-
import {sum} from './math.js';
-
we can't selectively load only the piece we need with require but with import, we can selectively load only the piece we need, which can save memory. Loading is asynchronous for 'require' butt can be asynchronous for 'import'

what is backend ? backend developer wo banda hai jo ki server and db program karta hai
-
why backend
download now par kuch ho to make websites more usable and purpose ful for the audience, to make websites dynamic -
why not frontend alone ?
with frontend websites are static and they are of not much use. -
what do we need ?
node js, mongodb, mongoose js, express js -
what should we make to hit big companies ?
CONTENT
-
node js install
install ka matlab hota hai aapke laptop/computer/tablet usmein files ko copy karna -
import and export
var figlet = require("figlet"); figlet("Hello World!!", function (err, data) { if (err) { console.log("Something went wrong..."); console.dir(err); return; } console.log(data); }); -
run the code
node ja hai khoob saara c++ ka code jo ki liya gaya hai chrome browser ke v8 engine ke code se aur is c++ code jisko liya gaya usey wrap kar diya gaya js code se and ye hume allow krta hai ke hum js code likhien aur ye js code accept karega and c++ ke basis par aapko ek server environmant bana kar deta hai, par sirf tab tak ye code chalayega jab tak apka node (v8 engine and js wrapper) chaalu hai
-- node js core usage & usage & understanding - http

middleware
middleware ek aisa function hai jo kisi bhi route se pehle chalta hai, jiska matlab aapka route chalne se pehle agar aap koi kaam karana chaahte ho to middleware ka upyog kiya jaa sakta hai
route pe chalne se pehle print karo chala on console
route chalne se pehle route pe hits counter ki value badhegi
iska matlab route chlne se pehle jo chalega woh hai middleware
sirf ek dikkat hai agar humara iddleware chl gya toh req jaam ho jati hai aur route tak nahi pahuch paati
-
node vs express :
node is the main thing express ke code se hum server ka code likh pate hein and server kaisa react karega wo bhi express ke help se likhte hai -
what is the real deal ?
-
what is express js ?
package, routing perform, server side management & many more.... -
why express js ?
http is difficult to use, express makes this easier. -
Routing
routes banaane ke process ko hum kahte hai routing. /profile /home /contact /profile/lucky/jhnvhjngb -
Middleware
middleware ek aisa function hota hai jo har route se pehle chalta hai, iska matlab saare routes mein koi bhi chale usse pehle middleware chalta hai and usmein likha code pehle execute hota hai node ke saath ek dikkat hai ki agar control ek baar bhi kisi middleware par gaya to control khud se agle route/middleware par nahi jaayega, use agle par lejaane ke liyein aapko push karna padega aur ye push kahlaayega next ko chalaana -
Request and Response
req mein saara data hota hai aane waale user ki request ki taraf ka, jaise ki uski location, info and other things. res mein controls hote hai jinke basis pe hum server se response bhej paate hai next is just a push so that our request moves to the next thing which should be executed. -
Route Parameters
aisa koi bhi route jiska koi hissa baar baar same rehta hai and kuch hissa baar baar change hota hai iske liye aap ek dynamic route bana skte ho /profile/:username /profile/lucky /profile/ansh /profile/sachin
URL mein jab bhi aapke paas ek aisa pattern ho
req.params
to make any route dynamic you can use :
at the place where you want to make it dynamic, and to access there value use req.params

Templates engine
html ke pass superpowers nahi hai calculation krne ki ejs is html with superpower
ejs setup karne ke liyein
-
ejs install
npm i ejs -
configure ejs
app.set('view engine','ejs') -
ek views folder banao
-
usmein ejs files banao
-
send ki jagah render karo => render karte waqt make sure aap views folder ke andar waali hi koi file kaa naam likhein, aur render fnc mein .ejs mention naa karein
ye ek style of markup se convert krke apko html dete hai
Template Engines : pug, handlebars, ejs, jade, etc...
ejs is very very similar to html
ek markup style jo ki baad mein convert hojaayegi html mein
data send via EJS File
res.send('index',{age:23});
- Static Files
images, stylesheets, frontEnd js setup karna
static files setup karne ke liyein:
-
create a folder called public
-
create three folders inside it, images, stylesheets, javascripts
-
configure the express static in script.js file
-
understand the path
app.use(express.static('./public'))
-
HTTP Methods - get and post
-
Error Handling
Error Handling refers to how Express catches and processes errors that occur both synchronously and asynchronously. Express comes with a default error handler so you don’t need to write your own to get started. app.get("/error", (req, res, next) => { throw Error("Something Went Wrong"); }); app.use(function errorHandler(err, req, res, next) { if (res.headersSent) { return next(err); } res.status(500); res.render("error", { error: err }); });
express generator
hum lgo ko kaafi saara kaam karna padta hai express setup krne mein iska matlab har baar jab hum naya project bnaayege to har baar fir se utna hi kaam krna padega, matlab ki poora code likho and sab kuchh setup karo, is time ko bacha sakte ho with help of express generator, use express generator and it will make the folder structure for you and it will also write the basic code for the project.
express genarator ek folder bana ke deta hai, jiska matlab aapko khudse folder nahi banana hai,to express generator saare files ko isi folder mein daal ke dega
steps to use express generator
sabse pehle jeevan mein ek baar laptop par install karo globally
npm i express-generator -g
to create new app anywhere: open cmd move to desktop create new app:
express appname --view=ejs
now use two commands
cd appname
npm i
open it to vs code
mondodb
har naye app ka data store hoga storage mein, par usey directly rakne ki jagah ek container mein rakhenge, us container mein sirf us app ka data aayega.
models (code) => collection (db)
schema (code) => documents (db)
ek app ka poora data => db
ek app mein variety of data hota hai par poora data hota app ka hi hai, par us data ka sub category kehlata hai collection
collection malab ki bola users ka data, ek user pe baat kri to hua document
// install mongodb // install mongoosejs // require and setup connection // make schema // create model and export
const mongoose = require('mongoose');
mongoose.connect('mongodb://127.0.0.1:27017/dbname');
// db create
schema matlab aapko ye batana hai banne waala har document mein kya kya hoga
create User :
const userSchema = mongoose.Schema({
username:String,
name:String,
age:Number
})
// har docuement kesa hoga document data
module.exports = mongoose.model(naam,schema);
// naam se bnega collection
// make collection
Find User:
router.get("/allusers", async (req, res) => {
// let user = await userModel.find();
// find one user (specific)
let user = await userModel.findOne({username:''lucky});
res.send(user);
});
create seperate array of object for creating users:
const users = [
{
username: "lucky",
age: 25,
name: "divyanshu",
},
{
username: "ajay",
age: 22,
name: "ajay",
},
{
username: "rahul",
age: 27,
name: "rahul",
},
{
username: "sachin",
age: 23,
name: "sachin",
},
];
Delete User:
router.get("/delete", async (req, res) => {
let deletedUser = await userModel.findOneAndDelete({
username: "lucky",
});
res.send(deletedUser);
});
dbs, models, schema, collections, documents
dbs, models, schema, collections, documents
understanding sessions
- session and cookies
creating sessions, using sessions across routes and destroying sessions
resave :
// agar session ki value change na huyi ho toh fir se save mat krna
saveUninitialized:false
//esa data baar baar save na kro
secret -> data encrypt kiya jayega
app.use(
session({
resave: false,
saveUninitialized: false,
secret: "holabholaholabhola",
})
);
router.get("/", function (req, res, next) {
// req.session.koibhinam = "lucky kashyap";
req.session.ban = true;
res.render("index", { title: "Express" });
// res.send("hello");
});
router.get("/checksession", (req, res) => {
if (req.session.ban === true) {
res.send("You are banned");
}
// console.log(req.session);
// res.send("check kiya hai console dekho");
});
create -> req.session.koibhinaam = koibhivalue
read req.session.koibhinaam
delete req.session.destroy(()=>{ })
Delete Session:
router.get("/removeban", (req, res) => {
req.session.destroy((err) => {
if (err) throw Error(err);
console.log(err);
res.send("ban remove");
});
});
creating cookies, using cookies across routes and destroying cokkies
Create Cookie:
By default package install hota hai
res.cookie("age", 23);
Read Cookie:
router.get("/read", (req, res) => {
console.log(req.cookies);
res.send("check");
});
Delete Cookie:
router.get("/remove", (req, res) => {
res.clearCookie("age");
res.send("clear cookie");
});
Task 1:
hume ek route banana hai, jismein ek page show ho aur waha par ek css use kra hua page dikhein
express js install express js boilerplate code express js ejs setup install ejs set view engine create views folder create ejs files render ejs files inside route
express static files setup architecture of public folder
const data =
{
name: "Lucky",
age: 23,
work: "Developer",
address: "Kalindi Vihar",
}
res.render('index',{data});
<h1>User Information</h1>
<p>Name: <%= data.name %></p>
<p>Age: <%= data.age %></p>
<p>Profession: <%= data.work %></p>
flash messages
jab bhi aap ejs page ko dekhenge waha par aapko kisi prakaar ka koi info dena hai, wo kehlata hai flash message, they are more like good looking alerts, warning and descriptions
install connect-flash
-
make sure you put connect flash in app.use function
-
kisi bhi route mein aap ko flash create karna hai
-
kisi bhi doosre route par app use chalane ka try karein
-
aap connect flash ko use nahi kr skte bina express session
express level-6 --view=ejs cd level-6 npm i npm i connect-flash npm i express-session
// setup express session
const expressSession = require("express-session");
const flash = require("connect-flash");
app.use(
expressSession({
resave: false,
saveUninitialized: false,
secret: "hello you connect with flash",
})
);
app.use(flash());
// to run
npx nodemon
localhost:3000
-
hum log chahte hai ki jab ham kisi route par jaayein jaise ki /failed us route par ek flash message bane aur wo flash message hum logo ko/ route par dikhein ejs mein
-
flash message ka matlab server ke kisi route mein koi data banana and us data ko doosre route kar paana
-
flash message aapko ye allow krte hai ki aap is route mein bane huye data ko doosre route mein use kr sko
-
agar login hojayein to login page ke baad profile page dikhado
-
agar naa ho to fir, mujhe is route se kisi aur route lejao jaise ki /error aur wha par dikhao failed
router.get("/failed", function (req, res) { req.flash("age", 23); req.flash("name", "Lucky Kashyap"); // res.render("index"); res.send("ban gaya data"); }); router.get("/checkkaro", (req, res) => { console.log(req.flash("age")); console.log(req.flash("name")); res.send("check karlo backend ke terminal par"); });

How do I find documents where an array field contains all of a set of values?
let user = await userModel.find({ categories: { $all: ["wwe"] } }); -
