✅ LET'S INTEGRATE APPWRITE

*We'll start by creating a new folder in our src directory, go Ahead create a folder with name Appwrite src/appwrite *

Now create a new file in that folder with name appwrite.auth.js

Now Following are the steps to completely setup the auth file :

1) Import Appwrite

import Appwrite from 'appwrite'

2) Setup SDK and Project :

For this step you'll need your project Id and end point , for that,

🔷Open your Appwrite console on http://localhost/console/

🔷Go to App settings.

🔷There you'll find your project Id and API End Point

Copy those details then put those details in setEndpoint and setProject

const sdk = new Appwrite();

sdk
    .setEndpoint('https://[HOSTNAME_OR_IP]/v1') // Your API Endpoint
    .setProject('5df5acd0d48c2') // Your project ID
;      .setProject('5df5acd0d48c2') // Your project ID
;

3) Creating User :

Now from here we'll be using appwrite's API, for this you can either use axios, fetch statement anything you're comfortable with

We'll directly return the response of the API from the config function.

export const createUser = (email,password,name)=>{
    return sdk.account.create(email,password,name);
}

And now we'll make use of this function in our Signup component file . We'll configure our handleChange function to create Account when user hits signup

Navigate to src/components/SignUp.component.jsx

Firstly we'll import createUser function from appwrite.auth.js
import { createUser } from '../appwrite/appwrite.auth';

Then we'll configure handle change and handle Submit function to respond to the event and create the user.

  handleSubmit = (event) => {
    event.preventDefault();
    const email = this.state.email;
    const password = this.state.password;
    const displayName = this.state.displayName
    createUser(email, password, displayName).then(
      (res) => console.log(res),
      (err) => alert(err.message)
    );
  };

  handleChange = (event) => {
    const { value, name } = event.target;

    this.setState({ [name]: value });
  };

For now, we're not doing much with the response, as soon as we setup loginUser functionality we'll add it here as well so as soon as user register he'll be logged in.

3) Logging User in :

Again, we'll go to our appwrite file to create a function loginUser which has two required parameters : Password and Email

export const loginUser = (email,password)=>{
    return sdk.account.createSession(email,password);
}

and we'll create a function to get the current logged in user.

export const getCurrentUser = () =>{
    return sdk.account.get();
}

account.get() doesnt have any required parameters.

...

We also need to create a function for Google SignIn :

export const signInWithGoogle = ()=>{
    return sdk.account.createOAuth2Session('google');

}

createOAuth2Session takes one paramter : Provider.

Now we'll configure our SignIn page to login user:
Navigate to src/components/SignIn.component.jsx

Firstly, we'll import loginUser and signInWithGoogle function in signUp file :
import { loginUser, signInWithGoogle } from '../appwrite/appwrite.auth';

  handleSubmit = (event) => {
    event.preventDefault();
    const email = this.state.email;
    const password = this.state.password;
    loginUser(email, password).then(
      (res) =>console.log(res),
      (err) =>console.log(err)
    );
  };

  handleChange = (event) => {
    const { value, name } = event.target;

    this.setState({ [name]: value });
    console.log(this.state);
  };

We also need to configure the googleSignIn button :

<CustomButton onClick={signInWithGoogle} isGoogleSignIn>
{''}
 Sign in with google {''}
</CustomButton>

5) Final Configurations :

We've successfully setup the complete authentication, all left for us to do is to configure our _app.js file to show user the homepage as soon as user is logged in.

Navigate to _app.js Here we'll import getCurrentUser function

import { getCurrentUser } from "./appwrite/appwrite.auth";

Now,In our App Component we'll define the state with property of user default to null

  state = {
    user: null,
  };

And we'll also use componentDidMount() lifecycle method to detect if user is logged in or not

  componentDidMount() {
    getCurrentUser().then((res) => {
      this.setState(
        {
          user: res["$id"],
        },
        (err) => {
          console.log(err);
          this.setState({
            user: null,
          });
        }
      );
    });
  }

If we don't get any error, that means we've a valid user so we'll set state to that user's id, otherwise we'll keep the user null.

Now, if user is logged in we must have a homepage to show it to them. So go Let's create a new file and call it homepage.jsx in src directory.

In that file we'll add content with a logout button that we want to show to the user as soon as user logs in.

For logout functionality we'll add a function in our appwrite file,

export const logoutUser = ()=>{
    return sdk.account.deleteSession('current');
}

account.deleteSession() takes a default parameter : SessionId but we can also put 'current' to denote the current session.

we'll import this logoutUser function in our _app.js and create a new function in our App component to delete the session and logout the user :

 DeleteSession = ()=> {
    logoutUser().then(
      (res) => {
        this.setState({ user: null });
        console.log(res);
      },
      (err) => console.log(err)
    );
  }

Now we'll pass this function as a prop to the Homepage from _app.js so the state will force the rerender of the page and bring user to the signin page again.

import CustomButton from './Utils/CustomButton'


const Homepage = (props)=>{
    return (
        <div>
            <h1>Welcome Home!!</h1>
            <CustomButton onClick={props.logOut}></CustomButton>
        </div>
    )
}

export default Homepage

Feel free to create and design Homepage file according to yourself.

Now navigate back to _app.js there we'll first import our Homepage then Conditionally render Homepage according to our state.

import { getCurrentUser } from "./appwrite/appwrite.auth";

  render() {
    return (
      <div>
        {this.state.user === null ? (
          <SignInAndSignUpPage></SignInAndSignUpPage>
        ) : (
          <Homepage logOut={this.DeleteSession} />
        )}
      </div>
    );
  }

Alright! So we've finally Completed our Login Page. Congratulations you've successfully built your first app with Appwrite!🥳

So now, without any further delay let's get started! 😃

Installing Appwrite :

Before installing please make sure your systems meets the minimum requirement of 1 CPU core and 2GB of RAM, and an operating system that supports Docker

In this tutorial we'll be using Docker to install Appwrite.
So before moving forward please make sure you've docker installed Install Docker.

The easiest way to start running your Appwrite server is by running our Docker installer tool from your terminal.

Unix :

docker run -it --rm \
    --volume /var/run/docker.sock:/var/run/docker.sock \
    --volume "$(pwd)"/appwrite:/usr/src/code/appwrite:rw \
    --entrypoint="install" \
    appwrite/appwrite:0.11.0

Windows :

CMD :

docker run -it --rm ^
    --volume //var/run/docker.sock:/var/run/docker.sock ^
    --volume "%cd%"/appwrite:/usr/src/code/appwrite:rw ^
    --entrypoint="install" ^
    appwrite/appwrite:0.11.0

Powershell :

docker run -it --rm ,
    --volume /var/run/docker.sock:/var/run/docker.sock ,
    --volume ${pwd}/appwrite:/usr/src/code/appwrite:rw ,
    --entrypoint="install" ,
    appwrite/appwrite:0.11.0

...

✅Setting Up Appwrite :
Once you've appwrite installed and running on your local machine, go ahead open up http://localhost:3000/ in your favourite Browsers and you should see this :

Go ahead and create your account, and login to you appwrite account.

Then click on create project and Enter your project's Name

If you see a console like this 👆 . Congratulations you've just successfully setup your first App with Appwrite!🥳

Hold on we're not done yet!😅

Let's move on to creating a complete authentication with Appwrite.

Under platforms tab Click on Add Platform and select New Web App Then name your web app and set your hostname to localhost (If you're hosting your appwrite somewhere else then feel free to enter domain of that address.)

As you hit register you'll find your platform added :

✅Getting Started with our Login App :
Navigate to Users Tab :

And make sure that Email/Password Auth is enabled.

now lets set up are NextJS app

Setting up NextJS project :

Before moving on Make sure you've installed npm or yarn.
To create NextJS app, create a new folder in your directory and open terminal in that folder then simply run

npx create-next-app@latest

yarn create next-app

then open that folder in your code editor.

To start your development server, run :

npm start

yarn start

in your terminal. Once your development server starts open up http://localhost:3000/ in your browser .

✅Installing Required Packages/Dependencies :

To move forward we'll first install all the packages that we're going to need while developing our app.

Installing Appwrite :

npm install appwrite

yarn add appwrite

✅Let's start building! :
Now, we have completely setup our Next Application. Let's start with building our App :
Open up your NextJS project in your code-editor and navigate to pages/_app.js
You should see default code :

Clear all the code in this file and we'll first start by import statements and setting up Home Class.

import Head from 'next/head'
import Image from 'next/image'
import styles from '../styles/Home.module.css'

export default function Home() {
  return (
    <h1> Hello World</h1>
  )
}

And you should see Hello world Printed in your browser.

We'll not be using Routing or Hooks in this tutorial just for the sake of simplicity, we'll keep this tutorial beginner friendly.

✅Creating and designing Signin and Signup Page:
We'll begin by creating a new file for our sign and signup page src/SignInAndSignUp.jsx
we'll import basic files in here and setup this file :

import Head from 'next/head'
import Image from 'next/image'
import './SignInAndSignUp.styles.css'
;



const SignInAndSignUpPage = ()=>(
    <div className="sign-in-and-sign-up">

    </div>
);

export default SignInAndSignUpPage;

Let's create Sign In and SignUp components :
Create a new directory in src name it Components src/Components

inside components create a new file with name SignIn.component.jsx
and SignIn.styles.css

src/Component/SignIn.component.jsx
src/Component/SignIn.styles.css

Now, In SignIn.component.jsx we'll create our form for SignIn.
Before that to keep our app well styled let's create our custom buttons and Form Inputs

In /src/ create a new folder called Utils/ Then a new file

src/Utils/FormInput.jsx and
src/Utils/FormInput.styles.css

and two files for custom buttons :
src/Utils/CustomButton.jsx and
src/Utils/CustomButton.styles.css

Why these many files? It is usually the best practise in code is to modularise our code in such a way that its easily
manageable and scalable.

CustomButton.jsx

import Head from 'next/head'
import Image from 'next/image'

import './custom-button.styles.css'


const CustomButton = ({children, isGoogleSignIn, ...otherProps})=>(
    <button className={ `${isGoogleSignIn ? 'google-sign-in' : ''} custom-button` } {...otherProps}>
        {children}
    </button>
)

export default CustomButton;

FormInput.jsx

import Head from 'next/head'
import Image from 'next/image'

import './CustomButton.styles.css'


const CustomButton = ({children, isGoogleSignIn, ...otherProps})=>(
    <button className={ `${isGoogleSignIn ? 'google-sign-in' : ''} custom-button` } {...otherProps}>
        {children}
    </button>
)

export default CustomButton;

...

Now Navigate back to SignIn.component.jsx file and we'll start building our signin page.
Firstly we'll import all the required files and packages
and then create SignIn Class Component with state that contians relevant fields :

import Head from 'next/head'
import Image from 'next/image'

import CustomButton from '../Utils/CustomButton';
import FormInput from '../Utils/FormInput';

class SignIn  {
    constructor(props) {
        super(props);
        this.state = {
            email : '',
            password : ''
        }
    }
}

Now Let's render our form through this :

import Head from 'next/head'
import Image from 'next/image'

import CustomButton from '../Utils/CustomButton';
import FormInput from '../Utils/FormInput';

class SignIn  {
    constructor(props) {
        super(props);
        this.state = {
            email : '',
            password : ''
        }
    }

    handleSubmit = async event=>{
        console.log('Form Submitted')

    }

    handleChange  = event=>{
        console.log('Input value changed')
    }

    render() {
        return(
            <div className= 'sign-in'>
                <h2>I already have an account</h2>
                <span>Sign in with email and password</span>

                <form onSubmit={this.handleSubmit}>
                    <FormInput type="email" name="email" label = "Email" value = {this.state.email}
                        onChange = {this.handleChange} required

                    />
                    <FormInput type="password" name="password" value = {this.state.password}
                     onChange = {this.handleChange} label="Password"
                     required />

                     <div className="buttons">
                    <CustomButton type="submit">Sign In </CustomButton>
                    <CustomButton onClick={this.handleSubmit} isGoogleSignIn>
                        {''}
                        Sign in with google {''}
                    </CustomButton>
                    </div>     

                </form>
            </div>
        )
    }
}

export default SignIn;

For now we're not doing anything with handle Submit or handle Change, we'll add functionalities to those function as we integrate our appwrite.

Now Let's add our SignIn Component to our SignIn and SignIn Page :
Navigate to src/SignInAndSignUp.jsx and import SignIn component and add it to the return statement

import Head from 'next/head'
import Image from 'next/image'

import SignIn from './Component/SignIn.component';
import './SignInAndSignUp.styles.css'



const SignInAndSignUpPage = ()=>(
    <div className="sign-in-and-sign-up">
        <SignIn></SignIn>
    </div>
);

export default SignInAndSignUpPage;

...

Let's see how our app looks so far, render the SignInAndSignUp Page from _app.js
Navigate to _app.js and import SignInAndSignUpPage and call it in the render function.

render() {
    return (
      <div>
        <SignInAndSignUpPage></SignInAndSignUpPage>
      </div>
    )
  }

Now Let's move on to SignUp Page
In components directory create two new files SignUp.component.jsx and SignUp.styles.css

Steps to understand the below Code :

Import all required files and packages
Define State with relevant fields.
Then We'll design our form using our FormInput components and Custom Buttons.
On Submission we'll trigger the function handle change which doesn't do anything for now, we'll assign it the functionality as we integrate appwrite.
Export the class Component.

import Head from 'next/head'
import Image from 'next/image'
import CustomButton from '../Utils/CustomButton';
import FormInput from '../Utils/FormInput';
import './SignUp.styles.css'


class SignUp {
    constructor(){
        super();

        this.state = {
            displayName : '',
            email : '',
            password : '',
            confirmPassword : ''
        }
    }

    handleSubmit = async event =>{

    }

    handleChange = event=>{


    }

    render() {
        const {displayName, email,password,confirmPassword} = this.state;
        return(
            <div className="sign-up">
                <h2>I do not have a account!</h2>
                <span>Sign Up with your email and password</span>
                <form className='sign-up-form' onSubmit={this.handleSubmit}>
                <FormInput
                    type = 'text'
                    name = 'displayName'
                    value = {displayName}
                    onChange={this.handleChange}
                    label = 'Display Name'
                    required
                />
                <FormInput
                    type = 'email'
                    name = 'email'
                    value = {email}
                    onChange={this.handleChange}
                    label = 'Email'
                />
                <FormInput
                    type = 'password'
                    name = 'password'
                    value = {password}
                    onChange={this.handleChange}
                    label = 'Password'
                />
                <FormInput
                    type = 'password'
                    name = 'confirmPassword'
                    value = {confirmPassword}
                    onChange={this.handleChange}
                    label = 'Confirm Password'
                />
                <CustomButton type='submit'>SIGN UP</CustomButton>
                </form>
            </div>
        )
    }
}


export default SignUp

Now Let's Import our SignUp Component in SignInAndSignUpPage.jsx file

import SignUp from './Components/SignUp.component
and then include that in return statement as well

const SignInAndSignUpPage = ()=>(
    <div className="sign-in-and-sign-up">
        <SignIn></SignIn>
        <SignUp></SignUp>
    </div>
);

Now, without extending this tutorial any longer, we'll integrate Appwrite to our app in part 2.
