Before starting Angular, you should know HTML, CSS, modern JavaScript (ES6+), TypeScript basics and have basic command-line skills. This article also covers setup, computer requirements and a two-week starter roadmap.
What prerequisites do you need to learn Angular? Essentials before starting
Short answer: Before starting with Angular you should have basic knowledge of HTML, CSS, modern JavaScript (ES6+) and TypeScript; Node.js and basic terminal/command-line skills are also helpful. A mid-range laptop is sufficient in terms of hardware. Below you’ll find setup instructions, a two-week plan, common mistakes and Opendart training options.
1. Prerequisite knowledge: what should you know?
Since Angular is a component-based framework written with TypeScript, the most critical prerequisite is TypeScript. If you don't know TypeScript's type system and basic syntax, the learning curve becomes steeper. Before TypeScript, you should at least know basic JavaScript—variables, functions, async/await, Promise, arrow functions, array methods.
HTML and CSS knowledge is essential: Angular apps mostly work with component HTML and style files. Understanding the DOM, form elements, basic CSS selectors, layout concepts like Flexbox/Grid and responsive design fundamentals will make your work easier.
2. Environment and setup: computer requirements and tools
Recommended minimum for the development environment: dual-core CPU, 8 GB RAM, SSD and a recent operating system (Windows, macOS or Linux). For larger projects and running multiple services simultaneously, 16 GB RAM is recommended. These specs provide a productive experience, but a mid-range laptop is enough for learning.
Required software: Node.js (LTS), npm or yarn, Angular CLI (ng), a code editor (VS Code recommended) and basic terminal/command-line knowledge. After installation you should be able to create a new project with Angular CLI, run the app and run tests.
3. First 2 weeks: daily plan and learning goals
I recommend a goal-oriented, hands-on plan for the first two weeks. Week 1: environment setup, TypeScript basics, create a simple project with Angular CLI, learn component and template structure. If you can spend 2–4 hours a day, practice will help solidify core concepts.
Week 2: focus on data binding, event handling, lifecycle hooks, services and dependency injection (DI). Build a simple CRUD app: list, add, edit, delete. Progress with small tasks and add a small feature each day.
- Day 1–3: Setup, TypeScript basics, first component.
- Day 4–7: Template binding, directives, pipes.
- Day 8–10: Services, HTTP requests, an introduction to RxJS.
- Day 11–14: Router, basic form handling, complete the small project.
4. Common beginner mistakes and how to avoid them
A common mistake is skipping TypeScript and jumping straight into Angular. TypeScript’s type system and class-based structure are tightly integrated with Angular; without understanding these basics, advancing is harder. Invest at least a few days in TypeScript.
Another mistake is ignoring RxJS completely. Angular uses Observables in many places; without knowing basic operators and subscription management (unsubscribe) you may encounter memory leaks and unexpected behavior. Start with small, repeatable examples and remember to implement cleanup (ngOnDestroy).
5. Opendart training and options
Opendart Academy’s Angular training offers a comprehensive 2-month program (120 hours + project development). Payment options include interest-free 12 installments by credit card or bank transfer. Sessions are scheduled weekday 09:00–12:00, 15:00–18:00 or 19:00–22:00; weekend slots are 10:00–15:00 or 15:00–20:00. Both live online and in-class options are available.
For corporate trainings, there are typically intensive 30-hour (6 hours/day) options with Basic and Advanced formats. The project development part of the training helps you consolidate what you’ve learned in a real application.
6. Quick comparison: self-study vs. instructor-led training
| Criterion | Self-study | Instructor-led Training (Opendart) |
|---|---|---|
| Structured curriculum | Variable, depends on your discipline | Ready-made, staged and project-focused (120 hours + project) |
| Feedback | Requires community/forum | Instructor feedback and live sessions |
| Cost | Low (most resources are free/cheap) | Paid; payment options available (card/installments, bank transfer) |
Frequently Asked Questions
1. If I'm starting from zero, what should I learn first?
Start with HTML and CSS basics, then learn modern JavaScript (ES6+). After that, move on to TypeScript. This order makes learning Angular much easier and more efficient.
2. How many hours should I study to learn Angular?
It depends on the person, but with intensive practice you may need around 100–150 hours to grasp the basics. Opendart’s 120-hour course + project part offers a structured approach to this timeframe.
3. Can I do Angular without Node.js?
For very simple apps, deep Node.js knowledge isn't mandatory, but Node.js is required for Angular CLI, package management and some development tools. Learning basic Node.js and npm/yarn usage will help.
4. How deeply should I learn RxJS?
For starters, Observable, subscribe/unsubscribe, pipe and a few basic operators (map, filter, switchMap, mergeMap) are sufficient. Advanced projects require more operators and error-handling knowledge.

Conclusion
Having knowledge of HTML, CSS, modern JavaScript and especially TypeScript before starting Angular will speed up your learning. For the development environment, Node.js, Angular CLI and a mid-range computer are sufficient. Spend the first two weeks on setup, TypeScript and basic components, then move on to services, HTTP, router and a small project for the most efficient progress. Opendart’s 120-hour + project courses and flexible session options (weekday/weekend, online/in-class) provide a structured path; for corporate needs there are intensive 30-hour options available.
