What I like most about this video is that you took it in two steps, so that allows me and my team to understand the context api first and THEN the reducer, which IMO are two separate and equally difficult concepts to understand. Thanks!
Man, thank you!!! You just save my life! I spend about a day read articles, but all of the articles about auth is is not explaining what's happening in details, but with your video I make it just for the 1 our! THAAAAAANX A LOOOOOT!!!!
Thank you for the tutorial, it was very helpful, even the way that it is presented: you dont just throw codes on our faces, you took the care to explain what each function does and how to use them. Greetings from Brazil!
He covered almost everything in react-navigation version 5. I highly recommend this video for development. lots of learning from it. Thank you so much. Looking more tutorials from you.
@@itzpradip Hey Bro, your videos are really awesome and you explained each and everything in a very easy way, can you please extend this tutorial and connect this app with firebase (for Authentication and all) please
Sir thank you very much, I am professional react native developer but watching your tutorial for getting knowledge about new RN features. I must say u explained and mentioned everything latest. Thanks again for your great playlist :)
Wonderful tutorial, i'm so glad i found your video. I've been struggling for hours, and you're literally the only one that made it simple! Thank you so much !!
Thank you very much sir. I must confess that your tutorials has really helped me in many projects and i can't thank you enough. Keep the good work going. Meanwhile, on your login tutorials, i would like you to add more details like, how to accept custom fields from the registration page. I want to learn how to collect users country and display name and add them to the firebase console. Please make tutotrial on this.
Can explain me how can I use redux store in my app after login using react navigation 5 with authcontext and there is possibility I can use authcontext in different module and import to app.js file I confuse how can I manage all auth and main app store in app thank you for your help.
Nice teaching Sir, I g through all the tutorials of mosh but can't implement the authentication, now I implemented the authentication working fine, Also If you do some code into different files it will understandable good
Hi Pradeep, I am trying to run your code but I am getting this error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. Check the render method of App. Also my react version is 16.13.1 as opposed to your 16.9.0
This is good brother. But hopefully you can group well your videos in a numbered manner for those which belong to a Playlist. You mentioned several series, upon checking I found videos are not in a clear sequence. Btw, yoir teaching and UI are really great, keep up the good work brother. Greetings from Tanzania 🇹🇿
Pradip Debnath, sure. I saw it; one request though, can you work on how to setup android studio from scratch with those avd, I'm very beat here. Consider both mac & windows users. Greetings from Tanzania 🇹🇿
Hello Pradip, Login and logout are working fine, when the app is foreground.. But when I logged in and close the app for 2 times. It does not logout . It stuck on same screen and then I need to close the app when open it then It logged out.
can you make one more tutorial with a sample API? I am not getting this point,, whether we have to call our API from signInScreen or App.js , if we call our API in app.js then how can we handle error handling like, no account found or incorrect password. If you can make another tutorial on this, then it will be really helpful
I connected this interface with a Python Flask API, and I think it's a best practice to call to your API from each Screen, using useState, helpers and whatnot. You can have your own config.js with your endpoint URL, and then export it to your screens. That's what I did. And if you use Expo or you struggle making requests to your API, use ngrok for echoing your local server to Internet. It's very simple to setup. Cheers!
thanks so much for these tutorials , helped alot , i have a question , i working on a project but iam using SQL instead of AsycStorage , meaning my user details will be saved in sql tables so do i need to use all those useEffect+useReducer+useMemo ,etc...??? hoping you can answer me soon , THANKS
I tried this out, and it's pretty much the same as he does it except replace the lines const userToken = String(foundUser[0].userToken); const userName = foundUser[0].username; with a fetch request to your server. You can then store and dispatch the token that the server returns. For me the fetch request looked like the below, where the user contains email and password. I added some conditions on the server side to send back 401 status if the username/password was invalid hence the checking of the status once I get a response back. function fetchToken (user) { return fetch(url + '/users', { method: 'POST', headers: {'Content-Type':'application/json'}, body: JSON.stringify(user) }) .then(res => res.status > 401 || res.status == 400 ? Promise.reject(res) : res) .then(res => res.status !== 401 ? res.json() : res.text()); }
Great tutorial, there is just one thing missing: how do you handle signup/signin errors that would occur in the backend and show them to the user with the given structure of code ? I can't find a way to pass the errorMessage in the loginState down to the signup or signin screen.
Hello, i was doing the same steps has you but i have an error when i compile, in App.js in the useEffect i have an error that says "warning: can't perform a react state update on an unmounted component. this is a no-op, but it indicates a memory leak in your application. to fix, cancel all subscriptions and asynchronous tasks in %s.%s, a useeffect cleanup function" i try to fix this error with clearTimeOut but this method dont fix the error, i would be great if you can help me
thanks for all bro, it worths , i just have a question... i have already made the first 10:23 minutes and then i tried to do it on my own, so ,do you think that i would have a trouble in the future without the another part of the code of the video?, thanks bro
You are doing great but Please make a video to elaborate what if i use Firebase for Authentication. I have done the Authentication using firebase but i'm not able to navigate to homescreen after authentication, since i don't have Authentication token in case of firebase.
Hola, tengo una pregunta. Quiero hacer una app tipo eBay y pienso que usar sockets podría ser bien. Pero aún no me queda claro de cómo integrarlo con redux en proyectos grandes por cuestión de performance. Podrías darme alguna idea o bien si tienes Algún código que me pueda ayudar a entenderlo mejor. Gracias.
Great video! Can you do a tutorial on how to implement IBM Watson services and Microsoft Azure machine learning services to react native apps? There are not many tutorials about these topics out there.
hello brother, can you show me how to make login authentication with laravel api,? i have a laravel project and ready with API, i have react native ui login
I had the same error, my issue was a typo... Instead of context I had content in some parts. For example instead of I had Check for any typos :) I was stuck on this for an hour till I realized.
@Pradip Debnath - Great tutorial. I watched the whole series and you explained it really well. I followed and implemented all of your code until video #7 in the series. After that I added in my firebase authentication code. In the SignIn screen on the button click I call my firebase login method. Soon as I implemented that code, I keep getting this error: "Error: Rendered fewer hooks than expected. This may be caused by an accidental early return statement. " Any ideas on how to resolve this error?
What I like most about this video is that you took it in two steps, so that allows me and my team to understand the context api first and THEN the reducer, which IMO are two separate and equally difficult concepts to understand.
