Today i got my first job due to your courses. Love and respect for you from pakistan
That’s awesome man, congrats. But it’s due to your hard work. I may have had a helping hand, but you did it. Great job 😊
Congrats man
congrats brother
Congrats bro.
Congrats
If you have the error where your variables have not been initialized = that's because typescript requires you to initialize your variables similiar to strongly typed languages. While you should have a default value set and work with this feature to really utilize typescript, for this small 'project' you could just put an exclamation mark before your variables and it will let you leave them uninitialized, for example: subscription!: Subscription; or @Input() task!: Task;
thank you! i had this issue. also when the button component was created, there was no import for Input, so had an error on @Input.
You saved me bro, thank you
Thanks a lot, I couldn't find the way to make it work
ty man! that was very helpful
Thanks. Spent the whole day trying to resolve this..
If you are using the latest version of ts then make sure to declare your variables in the constructor otherwise it will throw an error.
You can also use an ! sign after the variables. For example, @Input task!: Task;
hairtaishu anda
Could you please give another example? I am new to this
" ! " for required variable and " ? " for optional.
For Example:
text?: string;
day!: string;
I'm using Angular 12 btw.
please give snippet of how to do it in constructor
@@rajatnegi3896 at 25:40 i used the following code:
import { Component, OnInit , Input} from '@angular/core';
@Component({
selector: 'app-button',
templateUrl: './button.component.html',
styleUrls: ['./button.component.css']
})
export class ButtonComponent implements OnInit {
@Input() text!: string;
@Input() color!: string;
constructor() { }
ngOnInit(): void {
}
}
If you're using Angular 17, you do have to import the component, at least I had to in order to get this to work. Example below:
app.component.html
import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet } from '@angular/router';
import { HeaderComponent } from './components/header/header.component';
@Component({
selector: 'app-root',
standalone: true,
imports: [CommonModule, RouterOutlet, HeaderComponent],
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'angular-crash';
}
Thank you for this! I thought I was going crazy. Would be cool if OP would update this whole tutorial for V17 on upward.
Thank you!!!
thank youuu
Thanks man, you also saved me! I was under the impression that it had to do with Brad using a previous version of Angular, but I didn't completely understand the instructions provided in the error. Just as a suggestion: you should probably clarify that the code above is from app.component.ts., not app.component.html.
Anyway, you made my day :)
Ils in .ts ont .html but thank you
We need a full course Brad! You explain so much better than all those other instructors!
he kinda did. you can learn everything else on your own bit by bit, as you should
Hey Brad you have built really an awesome channel over the years. Even though I don't really spend much time with Web Dev anymore, I still like to come back from time to time and watch your content, as well as your insights on life/work/mental health etc... Truly amazing work
Thank you 🙏🏼
Thanks so much Brad. Thanks to this tutorial, I got my first job as a Software Engineer. Your life story is so inspiring and motivated me in my journey. I was a mechanical engineer and with so much hard work, I was able to shift my career. And on that journey, you played a most crucial role. May gods blessings be with you every day. Love and Respect form Sri Lanka ❤️
I think this is by far the most complete Angular tutorial done in two hours.. although it is not meant for a total beginner. Well done.. tq.
Unfortunately some of us are total beginner
@@dantshisungu395 for total beginners, I would recommend doing a lot of JavaScript learning (and also HTML and CSS) before learning Angular.
You cannot imagine how much happy I was to get notification about this course😍

You and me both!
You cannot imagine how much happy I was also.
I was fighting my way through Udemy course I bought for several days, and after watching 30 minutes of this crash course I already understand more Angular than ever! I am so happy this course appeared today! Thank you so much Brad! If I land a job first thing I'll do I will buy some of your courses.
Exactly my situation. "Angular Corre Deep Dive", terrible experience.
Finally!.. I've been waiting for Angular Crash Course for a long time👍
26:28 Had issues with the [ngStyle] attribute
I did instead:
[style.background-color]="color"
- Update, also just learned that the default mode for components is standalone now. Which means whenever he is going to the app.module.ts to import something, just import it to the component you need it in. standalone = modules are for only that component.
Thank you so much for that crash course! I think you covered all the fundamentals in building an Angular app.
No boring lectures, just straight coding which is what I need!
Probably the best Angular tutorial I've ever seen...
You really helped me to understand the framework and it's function!
Especially the combination of Frontend and Backend...
Thank you very much!!
Brilliantly explained ... I've been doing Angular related projects for a while but mostly it was a Google search to get different things done, with your course, everything is covered so wonderfully that now I have a better hang of it. Thanks a ton ... Keep up the good work !!!
I saw this tutorial 2 times, and it was well organized tutorial for a new learners means most concepts needed in Angular in just 2 hours with small todo app.
Did a good job!
For minor corrections which actually mislead begginers most of the time is when you used a function call directly into the *ngIf condition for add task button. It does effect an application of this size but it does affect larger applications as a function can always have a different output.
I've been following React, Vue, and Angular here, and in my opinion:
1. The advantage is that angular separate everything in the name of the component folder, which makes it easy to track the code.
2. Another thing is that the observable and subscription pattern ensures the asynchronous actions are clear and robust.
3. Default typescript.
The points mentioned are fonds of debugging to refactoring.
-----
3. However, one component has four files, and sometimes it could be messy. Lots of files are kinds of mental attacks when switching and looking for files.
4. Angular exposes more complexity to the developer that one must first learn the class, constructor, implement, and the public, private data types. Otherwise, it could be challenging to understand. Instead, React and Vue hides those complexities, which are more user-friendly.
5. ng generate xxxxx is annoying.
As a little help, you can also use "g" instead of typing generate, and the same goes to component with "c", so you can just use "ng g c" and the name of it. Hope this helps a little bit!
Thank you!
"Angular exposes more complexity to the developer that one must first learn the class, constructor, implement, and the public, private data types". You should be thanking Angular because of this. Becuase they are the very fundamental of software developing, if you don't need them with other libraries/frameworks today, you'll need if not now but tomorrow so learning the basics of OOP is always good. Also if you don't want, you may not use ng generate, you can manually create your files and register to modules yourself. ng g just makes everything easier.
Brad, we love your work and amazing tutorials. Big fan!!
This is a magnificent tutorial. A month ago I watched it, having had a background which included AngularJS several years ago, and now I'm flying with the Angular 13. It's such a fun framework to develop with once you're over the learning curve, and getting over it was 100% thanks to you. Great stuff!
Can I just say I love the little notes and comparisons you sprinkle in for people who are coming from React
Like saying "It's like props" or "You don't need to import this here" for example
It actually really helped me better understand this, and of course this is an amazing video as usual overall!
Thank you!
I was getting this error while declaring "onDelete(task)" (1:04:50): Parameter 'task' implicitly has an 'any' type.ts(7006) angular. I fixed declaring as "onDelete(task: any)".
It's also possible to change "noImplicitAny": false, at "tsconfig.json" file, but I didn't tried this way.
Thanks!!!
Thank you very much, your comment helped me right away.
I think it's better that I get used to declaring variable type, as that is a great feature of TypeScript.
By the way, to be more precise set variable type to Task.
As @Febo Bebo said, to be precise you should declare "onDelete(task: Task)"
I searched many other courses in yt and even though this is a crash course with older version than actual is still the best around. Keep going Brad!
Wanted to appreciate the effort you put to make the points clear. Great teaching skill❤️. This angular 2 hr course is enough to build great applications.👍 covers all topics. 👏
Since the project is fairly simple, you could embed the HTML and CSS code in the "ts" files reducing "files hopping", also you can create a minimal app with "ng new ##name## --minimal" , this way you reduce to 1 the number of files per component, furthermore you can create minimal components with the "-s -t" options at the end of the command.
you made that comment 11 months ago, the video was posted 2 years ago.
I was waiting for this course. And hope you do more Angular projects.
Thank you Brad.

Just recently started learning Angular since the company I work for requires you to learn it and I want to teach myself Ionic at some point. I use to not like Angular, but I am starting to really enjoy it. Mainly because of how simple it is to build components and services to integrate existing third party APIs. Hope it will be here to stay for a long time🙂
Same here. I was a vue dev before and after learning angular, I’m enjoying it more
This tutorial was awesome, normally I would just lurk but I felt a need to say how much I appreciate you making this video. As you led on, my background is with React so I agree Angular can be a little more tricky but I'm tempted to watch your React video as well just because I like your style so much and see if I pick up anything
25:30 @Input() text: string = "";
@Input() color: string = "";
Thanks, upvoted
Thanks a lot! this is so helpful :)
Was looking for this too, thanks
i started watching your video in 2017 (html website development) when i was jobless, and now when i hear your voice, it reminds me where i was and where i am! Thankyou!
God bless.
Never hurts to get a refresher on an Angular crash course. 👍
Hello, thank you so much for this 2 hour tutorial. It's a great help for me who's currently on bootcamp as a full stack developer.
56:22 Brad, you can double click a word to select it, type " and VSCode will wrap the word in quotes instead of what you would normally think it would do, which is to replace the word with a ".
By pressing CTRL+D you can also select further elements and then type " to replace all at once.
4 years ago I started my career with great help from traversy media tutorials. 4 years later I’m still learning new things and traversy always seems to have a good tutorial no matter what I am learning … this channel is the best. Thanks so much for all the content .
at 25:28 when Brad declares the @Input, if you get an error "Property has no initializer and is not definitely assigned in the constructor"' you can write it like @Input() text!: string; this is a temporary fix OR @Input() "text": string; is the same OR keep it the same as how Brad writes it and just assign it by writing this.text=" " in the constructor.
Thank you for your tutorials. I've been able to get a job! Full stack and in a great degree thanks to your videos and tutorials. You're the best!

This is what I hate w/ Angular. Every time I try to follow a tutorial, I'll randomly encounter this kind of hiccups.
Thank you sooo much Rajeev.I've been looking for a solution everywhere... thanks a lot
This fix worked. Thanks so much!
Hi Brad, I have been following your courses since past 5 years.
Amazing work here, really helped me brush all the key angular concepts.
Would love to see a short video on ngrx with angular.
Best programmer in the world, I really appreciate everything you do, truly learning a LOT from you
With Anuglar 17, when adding the button component props, I had to set the strings with empty values to get them to work.
Example:
@Input() text: string = "";
Thanks
thanks
Magnificent, love it so much! Exactly what I was looking for. You're awesome!
36:21 Had issues with the *ngFor
Fixed By:
In your tasks.component.ts file
- import CommonModule
- Add CommonModule to the imports list in your Component Declaration
I think this would be a great tutorial for my team to get up to speed on Angular. It was neat what you did with the Add button at the end with it detecting the route, which is a good concept to teach. However, your Button component has just become less generic, and if you use this route detection technique specific to your page, which may be one of dozens developed by a team in an enterprise, I doubt your pull request will be passed. Just saying. We have at least a dozen such custom controls in our project, so a great concept to teach. Thank you.
You are so clutch with the timing of this video. Thank you, Brad!
Really excellent tutorial. I learned so much from completing it! Can't wait to start the next one.
Yeah i think angular is best with typescript. Angular has a structure like a building. Its on point Brad!
Tip: Most of the pain of Angular is removed when you use its Template observable binding features instead of Component binding via the 'async pipe' (eg *ngFor let task of tasks$ | async). This cuts out about 80% of code in your component.ts as the async pipe handles all the observable subscribes/unsubscribes for you. Best rule I found: manual component subscription => code smells, auto template subscription => blessed life, all remaining mandatory subscriptions abstract away into a service if possible. Great crash course for beginners though, awesome content!
I would like to say I follow, but I don't. Can you point me to some more info on this?
this was amazing, i was waiting for this since a long time, thanks
This is a great Angular crash course. It is very practical, simulating to the real world. The teaching is very clear, well organized and presented. Strongly recommended!
I completed learning Spring Boot yesterday. Then, I wanted to learn a JS framework. I fixed on Angular.
And Now I get this notification.
Thank you Brad 👍✌️.
You are life savior buddy🙏
Go with Vue or React, it is better than angular
@@sachin__ak I will learn them later.. But the Orgs in India prefer Angular mostly... That's the reason I am learning Angular
@@sachin__ak Are the companies hiring for React here?
@@sachin__ak You mean it's easier to learn.
@@barryblack8332 yep and developer friendly too, vue js is the most simplest to learn
Very good and well made course! I liked the Subject/Subscription section.
I worked with React and Vue in many projects, but I think Angular, as a framework, is more elegant and well designed.
Thank you very much for this video.
I have been using Angular for few years now. It’s pretty easy and powerful framework. Also, it’s good for big, complex projects.
excellent! so clear and easy to follow, i am a 30 year IT professional and 18 year .NET developer and needed to look at this for new versions of my company's applications. Great first step and now that i see how the architecture is structured it is much less confusing than the first attempt made at understanding it. I am subscribed and can't wait to watch the other videos.
FINALLLYYYYYYYYYYY SOME FRESH ANGULAR IN UA-cam !!!!!
Waoooooh Greetings from Tanzania, Have been waiting for this one.
React na Angular Developer kutoka Tanzania visiwani (Zanzibar). Nimefurahi kukutana na ww hapa.
I love this tutorial because it is swift but still clear. Exactly what I'm looking for as a backend developer that doesn't need much background on the underlying concepts.
really good stuff. I haven't worked with angular in two years and this is perfect for refreshing
FINALLY. Been waiting for this one 🙏
yes, it took a long time
Coming from React I'm finding this quite challenging to be honest. My brain is so used to JSX and state, that all of this seems really hard to remember. Especially rxjs. I know it will take up quite a lot of time to be comfortable, but this video is a good starting point. I landed a job which requires me to code in Angular, hopefully I will be productive with it soon. Thanks Brad!
Right?! He started adding to task service and I was like "why is his beginner's tutorial stateless??"
If you're having trouble wrapping your head around writing Angular tests, try the suite-slimmer-angular npm library, makes it a lot easier
@@123userthatsme Is that the reason why when deleting a task he is doing it both from the db AND filtering it out from the UI?
I thought when you delete it from the db it automatically updates the UI since we have getTasks() in the onInit method
@@stefannikolovski3167 that's a good point. i don't know why i never thought of it
@@stefannikolovski3167 The ngOnInit() hook only gets fired when the component is created, so if you want to fetch the data again later you need to implement that some other way.
Generally speaking, when you’re interacting with data via HTTP requests, you don’t want to make unnecessary requests, so you don’t want to do another HTTP GET after the HTTP DELETE if you don’t need to (in this case you don’t need to).
So you just delete in the DB and if that is successful you delete in the UI.
I am new to Angular and was looking for some good resources. This is absolutely awesome! It includes step by step explanation along with some of the best practices
Excellent introduction to Angular; very helpful; concise but still complete. Thanks a million.
Outstanding 🙏❤️😍 I still got so much love for the Big Red A. People shit on because it's a little more challenging. They can't handle the heat of rxjs. Love you bro. 🙏
Angular is my favorite frontend framework 🔥
Thank you very much 💖
And probably the only one you know if this is your favorite.
@@jgttech
Well, I dealt with other frameworks like Vue and Svelte as well as React library and in the end I found that Angular was the best choice for me but unlike you, my preference for a specific framework doesn't mean that I don't respect other frameworks.
Looking forward to be taking future courses from you. Love and respect for you from Ottawa, Ontario Canada
Brad, you are always on time! That's exactly what I was looking for
Great Learning, THANK YOU.
love it, i was wating for new angular course of you, keep going excelent course, btw what theme are you using? XD
Github theme.
Thanks. I always find myself back on your channel anytime I need to learn / refresh my memory on a framework. Great videos.
Thank you so much Brad!!! Exactly what I am looking for! Very informative!
1:07:16 Your event binding (onDeleteTask)="deleteTask(task)" is not actually taking the task from the event data. It's getting the task as part of the ngFor directive, ie. from the current component's state (tasks.component.ts). To call deleteTask() with the actual data from the onDeleteTask event, you need to call deleteTask($event) when this event fires. $event is Angular convention and is any object that you might have passed to the emit function of the EventEmitter (ie. 1:06:30 this.onDeleteTask.emit(task)). So basically $event === task here, the actual task that is correlated to the correct X icon/button that was clicked. Both version are correct functionally and do the same thing in the end, but to me, it seems more logically correct to use the actual data that comes with the event when you handle one and not handle some other data in this case.
I am getting an error when I use either task or $event during compiling. I am using the latest version of Angular
@@Blindbuymovieguy yea same, did u manage to fix it ?
I figured my error in particular:
I had @Output() onAddTAsk: EventEmitter = new EventEmitter(); istead of
@Output() onAddTask: EventEmitter = new EventEmitter();
in the add-task.component.ts
So key sensitivity is something to look out for :)
I was looking for the people that noticed this as well
Hate being stuck on the minute 1:05:01. Anyone have an easy fix? Did he do changes in tsconfig.json?
Angular is good actually. It doesn't deserve the hate it gets. It's sad. I thought of finally deep diving into angular after some years, and you release this video exactly after that. Thanks
@@chitrangsharma bro even updates are not crucial in angular if you learned angular since v2 it still the same until now it gets update on the performance and internal stuff not the syntax or features, and it does not follow MVC Angular follows a component-oriented architecture, mvc can only be on the backend
It's hated because:
- it's named poorly - it shouldn't be named Angular anymore, because still people think about Angular 1 after hearing "Angular" to this day (which is ridiculous for me but it is what it is unfortunetly. Blame people)
- it's not as minimalistic as React or Vue - but people don't know that it's good (really good), because only Angular gives you 100% compatible features like SSR, PWA etc. right away and it well suits corporate apps with it's strict way of doing things which reduces amount of bad code and architecture by a lot
Maybe some day this weird JS community will finally see how many problems Angular solves in this ecosystem
@@DEVDerr You would be surprised how difficult it is to give a good name to your stuff.
But then I think they can do better, these guys went from renderer to renderer2(like HOW).
There's a componentFactoryResolver and
resolveComponentFactory.
There's more of these.
This is not a deep dive into angular by any means
Much agreed. Angular allows me to do almost everything I want without downloading any additional dependencies and have a robust and performant web app. But for some reason people were tricked that "Classes" are a bad thing, that JSX somehow is super amazing and Angular directives are not "pure" html and SUPER confusing. Also, only React developers have become NOTORIOUSLY worried about immutability and components knowing their own state, eventually spawning some of the weirdest concepts (like creating a component for a component that holds its state...). Angular and Vue all the way. Maybe now Svelte too... but I'll wait for what Sapper will be replaced by.
Brad your work is really amazing. You explain and teach things I really want to learn. When it comes to selecting a JS framework, I found that Angular is the option to go with but I didn't go for it because I thought it's based on Typescript; but now at the Intro of this course you stated that using Typescript is optional. It made me feel good, get up and invest my time in working with Angular.
Thank you for this wonderful tutorial! You explain things for WHY you are doing them. Things really started to click after your tutorial. Thank you!!!
This was a really awesome course that I had ever followed. The tutorials I used to watch used the localstorage to store the data. But you took us on a full journey of angular. Thanks Brad!

I like following along with the exact version when I watch tutorials. This reducing the unrecognized errors you encounter from newer version. If you want to do the same Traversy is using angular 11.2.12 with Typescript 4.1.15. I used NVM to change my version of node to 10.13.0 (and then "nvm install-latest-npm" to get to a usable npm version)
Thank you for the video, Brad! I am currently learning Angular for a new job and this was super helpful. I gravitate towards React more, but this was super easy to follow!
same for me. I worked with react previously but a new internship came along and told me learn angular. This helped a lot !
I followed this entire course and made my first project in angular, thank you! Your presentation was really good,and easy to follow through. One suggestion I only have is to name variables differently across components for example at 37:57, too many things had name 'task. It all works well like that, but as a beginner who seeks to understand how parameters are passed and how angular works in general, it would make more sense to me if I was able to discern exactly which property is referenced and where.
Did you use Angular 15 ? or which version exactly ?
