Walk into the interview
knowing the lifecycle cold.
Drill the request pipeline, dependency injection, microservices, testing, and security as flashcards; pressure-test yourself with a quiz; and design real backends with coding & system-design prompts. Everything runs on-device — nothing leaves your browser.
Everything in here
Today
→Your daily drill: due cards + a coding & design prompt, with a streak.
Flashcards
→Drill NestJS Q&A and grade yourself — progress saved in your browser.
Quiz
→Multiple-choice checks on lifecycle, DI, and security — explained feedback.
Practice
→Coding & system-design prompts — try first, then reveal the answer.
Search
→Find anything by keyword or meaning (on-device AI), and ask the AI tutor.
Progress
→Tick off readiness milestones until every box is green.
The method — learn it faster
This guide is built around how memory actually works. Use these and you'll retain more in less time.
Active recall
Retrieve the answer before you reveal it. Flashcards and practice prompts are built for the struggle that makes it stick.
Spaced repetition
Grade each card and the app schedules its next review. Clear the Due pile daily to catch cards right as you'd forget them.
Interleaving
Mix lifecycle, DI, microservices, and security instead of blocking one topic — it fights the false fluency of re-reading.
Active problem-solving
Coding prompts (guards, interceptors, providers) and system-design prompts make you produce, not just recognize.
A 20-minute daily loop
- 1. Open Today and clear the cards spaced repetition says are due (grade honestly).
- 2. Do one coding + one system-design prompt — try before you reveal.
- 3. Take a short quiz on a weak topic, then check off a readiness milestone.
