Forms are the core feature of many apps. Being skilled with reactive forms should be a high priority for virtually all Angular developers. I hope this video helps solidify the core principles :)

Hi, do you have a complete couse of angular and firebase ? If you have please send me the link.

[@matthiaskublbock9149]

God, I really love your videos. As a beginner Angular developer, these videos really help me out a lot. Please don't stop making such videos you don't even know how many people you help out with this :)

[@Fireship]

Great to hear that, I really want to build a comprehensive collection of videos like this one.

[@sifo_io]

@@Fireship Suup fireship Im coming from the future to say thank you!

[@gunitakon]

I once had to redo an Angular app's core form from scratch. Initially I had very fuzzy understanding of reactive forms, but the second time when I had to redo it, I had a much clearer idea, and was able to restructure it much better, however, I absolutely love watching these The Basics series because it really clears some very basic stuff that'll make you realize there's a better way. Looking forward to more of The Basics. Especially the dynamic forms.

[@akmalnawfer970]

first of all I didn't think you could cover this much in reactive forms in just 16 mins. kudos awesome video

[@jorgeriveramx]

This is easily the most awesome coding channel that there is in youtube. Thanks a lot for your work

[@ekings2119]

(No sarcasm) I appreciate how your videos assume we are competent enough developers that don't need every single thing spoon fed. Thanks for your concise approach to teaching.

[@malik.alimoekhamedov]

[@edwardrouth]

[@SamuelBello64]

I've been searching a solution to my problem for close to 3 weeks now. I've a problem of submitting my values in the form and as well making my email test if it's wrong with the form validation in angular material. I'm glad you made this video.. Like God sent you to send this video because of me. I'm grateful Angular Firebase.. I also look forward to my cap please 😊

[@Fireship]

Thank you for this comment. I've run into these issues myself and I like to share my favorite solutions.

[@flakky1]

Great as always Jeff, if possible please do some more basic tutorials with firestore, specifically how to create custom query with load more button, i know you have 2 tutorials with infinite scroll, which can be used as a starting point, but it has some weird behavior if switching routes. Thanks for sharing knowledge, i learn alot from your videos.

[@Fireship]

Great to hear that :) My next pro video will cover Firestore with Reactive Forms, but have a ton of other Firestore stuff planned

[@Josa192]

[@Fireship]

Thanks, a little late for the hat tho. Check out the latest video on the channel for a chance to win some swag :)

[@ronitmishra8917]

Damn, I was still learning Reactive forms when your reply popped up. You're really fast, Mr. Flash! Anyways, I'll be tuned in for your latest uploads. I get every thing I want to learn from your channel regarding Angular. So I'll be here only. You can consider me your loyal subject.

[@tkd5041]

[@jseh_]

simple and clean explanation xd

[@TheBlader55]

I love you. Keep making this videos!!

[@MZ-uv3sr]

Now I need to figure out custom validators, and why and when I need an async one I love this video. One thing...the music starts a bit too soon before it's really done and is kind of distracting.

[@supercompooper]

This is insane and has to improve. It's far to hard to handle what is a very common pattern. We should instead be describing our form once, and the goal we want to achieve, and have a form generator. This has hundreds of places where a human can make a mistake or miss some edge case.

[@sveinsoermo9883]

High quality video again.

[@Fireship]

Thank you Svein!

[@BytesAndBrackets]

Great learning

[@rajaera]

This is awesome , Thank you!

[@sample1801]

Hey fireship ! This video is great ! But what's the angular version is this ??

[@pgc1721]

Hi Thank you very much. What's Angular icon theme you are using ? Please let me know. Thanks

[@wes443]

has a video been done on project structure? like what goes into core and shared modules and just the best practices for structuring an angular application

[@jessyndaya9487]

keep calm, we love it!!!! :)

[@ttma1046]

Nice video!

[@ms-pf9ow]

Helpful ❤

[@Blixzful]

Good work! What did you use the tap and first rxjs operators for? Can you also provide a video for a use case, where you have to use ngModel two way binding (f.ex to handle Promise rest API data calls)? Cheers Jeff!

[@Fireship]

Good catch, I was going to use tap and first for preloading data into the form, but ran out of time. I will cover that in my next pro video about "Advanced Form Techniques with Firestore"

[@edgarsantos7782]

Hi great video. I have a question about 11:07. You see I've been using angular from version 2. And I would use getters. I've changed job and had an argument with a developer and he refuses to use getters and would not allow me to do so. The thing is he told me (correctly) that angular change detection runs like a trillion (exagerating) times per second, if you are using functions it will run those everytime. I don't see harm when there is only returning a varible access (maybe I'm wrong), but if you are dong more things inside that getter might have performance issues? What you think?

[@Kabatemasmusic]

When you show us the nested forms, then editing the cellphone also edits the homephone datamodel and vice versa... How to fix that?

[@mpamparimpampatzi5374]

my problem exactly

[@janisbrivvirs2528]

I am using angular for two years but never used a nested forms... :))

[@Fireship]

You're a lucky one then ;)

[@janisbrivvirs2528]

Don't think so... Combining multiple independent forms is an overkill compare to nested solution :D

[@jorgeriveramx]

Is there any reason to create the form in the ngOnInit life-cycle hook instead of the constructor? I ask because I've seen other tutorials where they do it in the constructor.

[@romanroman9638]

I'm repeating after the video. How can I handle this error: error TS2564: Property 'myForm' has no initializer and is not definitely assigned in the constructor. ?

[@yuridigital]

very informative!

[@musician9470]

Any tips on how to effectively create getters for forms?

[@arihasan3423]

Great video, and also I loved how quickly you showed the code without needing to type. I know ur using VSCODE, but what plugin do you use to insert the code, snippet?

[@barmetler]

What do you guys think of angular material? In my opinion, it's kinda annoying that you have to essentially fight against their css, sometimes requiring very specific selectors of !important. I feel like it's intended for people that just want to slap some components into their html and not adjust anything but colour and stuff... For me, I actually prefer just implementing the styling from scratch, with normal html elements, depending on how I want things to look... Maybe I'm doing something wrong though and there's a way to raise the priority of your custom css file for a component, if that's even a thing Edit: order of loading css files doesn't help, since their selectors are very specific and their style sometimes even uses !important

[@rahmaniaboubeker4205]

thanks this is very helpfull

[@dule605]

Did you ever think about making a complete angular tutorial on udemy? Because that would be great and it would help us juniors alot. Thank's in advance

[@xucongzhan9151]

Clear and concise, really helpful! Thank you so much!

[@alanlal5625]

Where should I be using the template driven forms ? Is the reactive forms always the better one to use ?

[@Fireship]

Template forms are useful for very small forms that don't need validation bc they are easy to setup. Anything beyond simple should be reactive IMO.

[@PeterSotosEPT]

Can you show an example where the nested form is a complex custom component with its own form?

[@PeterSotosEPT]

I figured it out with some help. here is an example: github.com/psotos/AngularFormContainerProblem

[@AlekseyNew]

Nice as usual :thumbup

[@Fireship]

Thanks Alex!
