SimpleStack bolo: Python, Flask, Jinja2, SQLAlchemy, SQLite, HTML/CSS/Bootstrap, maybe Chart.js.

SimpleJWT teen tukde ki signed chitthi: header.payload.signature. Padhi ja sakti hai, badli nahi ja sakti.

Encoded (Base64) + signed, encrypted nahi (JWE alag). Payload mein password mat daalo — koi jwt.io pe dekh lega.

Login pe server secret se HMAC (HS256). Har API Authorization: Bearer <token>.
Expiry exp. Change payload → signature fail → 401.

Session MAD1 server yaad rakhta. JWT MAD2 client rakhta, server stateless-ish.

Example

eyJhbGciOiJIUzI1NiJ9.{"sub":1,"role":"admin"}.signature
# Authorization: Bearer <token>

Project example: POST /login → token LS. fetch interceptor header. @jwt_required APIs.

Viva tipAlgo HS256. Secret env var. jwt.io pe payload dikhao, secret public site pe mat paste.

SimpleDifferent origin Vue vs Flask — browser CORS check. Server Allow-Origin.

Failed = frontend error even if curl works. Examiner curl vs browser.

HTTP verbs + status REST ki zabaan. GET read, POST create, PUT replace, PATCH partial, DELETE remove. GET typically no body.

Status: 200 OK, 201 created, 202 accepted (Celery task), 400 bad input, 401 no/bad token, 403 role nahi, 404 missing, 409 conflict (double book), 500 server.

AJAX/fetch page reload nahi. SPA poori isi pe. Postman se bina Vue ke API prove karo — examiner pasand.

Example

from flask_cors import CORS
CORS(app, resources={r'/api/*': {'origins': 'http://localhost:8080'}})

Project example: Flask-CORS localhost:8080.

SimpleCron/crontab = schedule pe job. Celery Beat app-level cron (daily email). OS crontab alag.

Example

crontab(hour=18, minute=0)  # har din 6pm

SimpleParent-child: parent template mein child component. Props parent→child, emit child→parent.

SimpleVue = UI ka smart assistant. Data badlo, screen khud update. MAD1 Jinja har click pe naya HTML.

Progressive frontend framework. Components, reactivity, directives.

MAD2 SPA: ek index.html, Vue Router pages, Flask sirf JSON.

Fayde: easy, SFC, docs. Vs React: templates HTML-like, course sikhata hai. Vs plain JS: baar-baar DOM mat chhedo.

Example

<!-- HelloWorld.vue -->
<template>
  <h1>{{ msg }}</h1>
</template>
<script>
export default { data() { return { msg: 'Hello' } } }
</script>

Project example: Navbar.vue + views (Login, Dashboard). data() / setup() reactive. fetch APIs.

Viva tipFayde: easy, SFC, reactivity. Vs React: chhota learning curve. Vs plain JS: UI state auto-update.

SimpleGentle curve, SFC, docs, reactivity, chhota vs Angular. Over React: HTML templates, course.

Over plain JS: components router ecosystem.

SPA = ek HTML, Vue Router se views, full reload nahi. MPA = MAD1 Jinja har URL naya HTML.

Vue Router: routes array, router-view, router-link, meta.auth + beforeEach guard. Dynamic /venues/:id → $route.params.id.

Vite/CLI SFC + npm build dist/. CDN script tag, no SFC. Jo tumne use kiya wahi justify. Flask send_from_directory('dist') production pattern.

Project example: Justify Vue not React: taught + time.

SimpleCode explain formula: input kya aaya → auth/validation → DB change → response/UI.

Viva tipFunction signature + 3-4 important lines + edge case.

SimpleAuthentication: tu kaun hai? (login). Authorization: tujhe permission hai? (role check).

Example

# auth
if check_password_hash(user.password, pwd):
    session['user_id'] = user.id

# authz
if user.role != 'admin':
    abort(403)

SimpleYes modal body / no layout router-view. Honest. router-view slot-like outlet.

Did you use Slots.

Component = reusable UI block (Navbar, Card). Props parent→child data, emit child→parent event. Slots parent HTML inner content.

computed cache + reactive derive (filtered list). watch side-effect (query change pe API). methods events. ref() primitive, reactive() object. Vuex/Pinia global store; localStorage persist, store nahi.

SFC: template + script + style ek .vue file. Parent-child exam favourite: list parent, row child :item + @delete.

Project example: Open slot if any.

SimpleValidation = input rules: required, email format, length, unique. Frontend UX, backend security — dono.

Example

if not email or '@' not in email:
    flash('Invalid email')
    return redirect(request.url)
if User.query.filter_by(email=email).first():
    flash('Email taken')

SimpleCache baar-baar DB/compute na karne ke liye result yaad rakhta hai.

Browser cache, Flask cache, Redis. Example: dashboard counts 30 sec Redis mein.
Cookies alag (client data). HTTP 304 Not Modified bhi cache related.
MAD1 mein optional. Scale poochhe to pehle indexes + cache, phir extra servers.

SimpleLS never auto-sent. Cookies auto to domain CSRF surface. Difference LS and Cookies.

JWT LS not in Cookie header.

Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).

4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.

Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.

Project example: Network Cookie vs LS.

Project example: Network Cookie vs LS.

Definition style question: 1 line simple Hinglish + project example + mini code.

Template'X ka kaam Y hai. Mere project mein Z jagah use hua.'

Example'Session login state rakhta hai. session[user_id]=u.id login pe, logout pe session.clear().'

Agar topic Vue/Celery/Redis ho aur project mein nahi hai to sach bolo, theory example do.

SimpleRBAC = Role Based Access Control. Roles (admin/user) se permissions milti hain, har user pe alag list nahi.

Example

if current_user.role != 'admin':
    flash('Not allowed')
    return redirect(url_for('user.home'))

SimplePehle 1-line definition, phir apne MAD1 project mein file dikhao, phir chhota example.

Suggested flow1) Concept kya hai?
2) Mere code mein kahan?
3) Example / demo
4) Edge case

Example

# related file: models.py / routes / template
# formula: request → check/auth → DB → render/redirect

Viva tipExact line yaad nahi to honestly related part dikhao. Bluff mat karo.
