Auth Flow

Usage

Set up a new firebase project
Go to Authentication and under Sign-in Method enable Email/Password

Fill this firebase config to your config inside ./navigation/AppNavigator.js

```jsx
const firebaseConfig = {
	apiKey: '',
	authDomain: '',
	databaseURL: '',
	projectId: '',
	storageBucket: '',
	messagingSenderId: '',
	appId: '',
};
```

and you good to go!

Prebuilt UI Screens

There are 3 screens included inside ./screens/auth and one more thing its included with the firebase auth function, so you don't need to create the function. The ilustrations I use undraw

Login screen ./screens/auth/login.js
Register screen ./screens/auth/register.js
Forget password screen ./screens/auth/forget.js

I personally use these screens on my project TiktTeng in early stages before the redesign, feel free to use these screens ❤️

React Navigation Auth Flow

The checking logged users process is inside ./provider/AuthProvider I use React Context, you can add more functions like get the data of the user and store it to the context (better static data, ex: uid)

Inside the navigator ./navigation/AppNavigator.js There's 2 stack navigator :

<Auth/> → for not logged in users stack
<Main/> → for logged in users stack
<Loading/> → for loading screen

export default () => {
	const auth = useContext(AuthContext);
	const user = auth.user;
	return (
		<NavigationContainer>
			{user == null && <Loading />}
			{user == false && <Auth />}
			{user == true && <Main />}
		</NavigationContainer>
	);
};

Custom Components

Layout

props	required	value
navigation	`true`	navigation prop
title	`optional`	string null/false → Top bar navigation not appeared
withBack	`optional`	boolean true → back icon with back to previous screen function

import Layout from '../components/global/Layout';
export default function ({ navigation }) {
	return (
		<Layout navigation="{navigation}" title="Home">
			{/* put your content here */}
		</Layout>
	);
}

Add Custom fonts to your project

Custom font I used in this template is "Ubuntu" (Google fonts)

Find your google fonts here

Install the font

expo install @expo-google-fonts/YOUR_CHOICE expo-font

Add to your project. Example in App.js

...
import {
	Ubuntu_300Light,
	Ubuntu_300Light_Italic,
	Ubuntu_400Regular,
	Ubuntu_400Regular_Italic,
	Ubuntu_500Medium,
	Ubuntu_500Medium_Italic,
	Ubuntu_700Bold,
	Ubuntu_700Bold_Italic,
} from '@expo-google-fonts/ubuntu';

...

...
	async function loadResourcesAsync() {
		...
		Font.loadAsync({
			Ubuntu_300Light,
			Ubuntu_300Light_Italic,
			Ubuntu_400Regular,
			Ubuntu_400Regular_Italic,
			Ubuntu_500Medium,
			Ubuntu_500Medium_Italic,
			Ubuntu_700Bold,
			Ubuntu_700Bold_Italic,
			}),
		]);
	}
	...
...

Edit the Custom Font component
