User AccountsAuthenticate the CustomersConclusion Create a Copy of the Design Project ObjectivesIn this lab you will learn how to Kick off a design project using the Amplify templateTheme the design to your tasteCreating the Project DesignWe need to make a copy of this design file to get started The design was created by cloning the official AWS Amplify UI template and adding a different theme We can see the design was created you can zoom to show clearly Even though we ll use the customized design file for this project let s also see how to use the official UI library for future projects So in the Figma community search for AWS Amplify UI Kit and open the kit maintained by the AWS Amplify Team Choose figma name AWS Amplify UI Kit of AWS Amplify Click the Get a copy button to create a copy of the AWS Amplify UI project into our Figma account The AWS Amplify project contains the following pages A readme describes the UI project Primitives like buttons and form controls that make up the component My Components these are reusable components composed of primitives that we can drop on our website Examples this page shows how to use the components Editing the Project design themeWe can change the default theme of the official UI template to do that we need to install the AWS Amplify theme editor from the Figma community page Let s search Amplify themefor the AWS Amplify and open it click the plugin tab and click try it out it Click Primitives and Press the command keyboard keys to bring up the Figma command palette back to the Figma project Let s click Component for the AWS theme editor and open it navigate to the components tab and search for button primary And set up the color you can choose like picture Then click Save When save we should see that we updated the color of the button on the primitives page NoteAmplify recommends that we don t change the primitives directly the components artboards are locked to prevent accidentally changing the Components The primitives have a one to one mapping with the AWS Amplify React UI library which we ll use when pulling the component into our react project Changing the primitives will make it fall out of sync with the React UI library Amplify will always give us an object containing the themes we are using We can then pass it to the React UI library to customize it On the components page you should see that all button colors have been updated accordingly the same thing on the example pageThe Design We ll UseInstead of Official Amplify UI Kit in this project we ll use an already customized one that suits our membership website The following is what was edited On the Primitives page the button color was changed to orange and the background color to dark blue etc The Components page utilizes the customized theme and creates the following components The Hero component The testimony component The story componentThe Nav Component and the Footer component On the Examples page a complete website was built using the components The website includes a landing page and a paywall protected page What s Next In the next lesson you will learn how to setup an Amplify project Create an Amplify Project ObjectivesIn this lab you will learn how to Create an Amplify projectSetup authenticationAdd data modelGenerate fake data for your modelImport the components from FigmaCreating an Amplify ProjectLog in to the AWS console or create an account here Search for AWS Amplify from the search bar and select it from the list of services Click Get StartNext click on the Get Start in item Build an app Give a name membership website to the application and click the Confirm deployment button Wait to setting upAfter the deployment process click on the Launch studio button to launch a staging studio in a new tab In the Amplify studio we ll add authentication to the project model a database and deploy it add contents to the database and import UI components from Figma using the UI builder Adding AuthenticationNavigate to the authentication tab since we need only signed in users to access our content The login mechanism stays the same then in configuring the sign up section click the password protection setting and make the password as strong or weak as possible Uncheck all other checkboxes except the Include lowercase characters checkbox and click Deploy to deploy the authentication Next click in Confirm deploymentThis deployment can take a few minutesIf successfully it will showCreating Data Model Navigate to the data section and create the following data models Testimonial this will have the id name avatar and testimony fields Post this will have the id title body and description fields and also a readTime field with the type of integer After creating the models and adding fields click the Save and Deploy button to deploy the database Adding Content to the Data ModelAdd this page we will seeNavigate to the content section select either the Testimonial or the Post table from the select table dropdown and click on Auto generate seed data For the Testimonial table set rows to add constraints like in the below and click the Generate data button After generating the data we can then update the avatar fields with desired avatar URLs Set the rows to for the Post table add constraints and click the Generate data button to seed the table Importing UI Components from FigmaWe ll import the customized design from Figma into Amplify Studio grab the URL from Figma and navigate the UI Library tab Next click the Get Started button and paste the Figma design URL in the input field and click on Continue After successfully importing the Figma components click on Accept all changes Next click on Accept all to accept all the imported components Now we have all the components in the Amplify project the same way they are in Figma What s Next In the next lesson we ll setup a Next js project Setup a Next js Project ObjectivesIn this lab you will learn how to Setup a Next js projectSetting Up a Next js ApplicationTo create a new Next js application let s run the following commands in our terminal npx create next app membership websiteAfter creating the application we ll navigate into the project directory with the command below cd membership websiteNext install the following dependencies aws amplify to give us access to the amplify SDK aws amplify ui react this dependency has a one to one mapping with the primitive s page in our Figma UI design fontsource inter so we can tweak the fonts of our project The command below will install the above dependencies npm install aws amplify aws amplify ui react fontsource interA few final steps Create a reset css file inside the styles folder in the root directory Copy the globals css properties and paste it inside the reset css file Delete the styles in the globals css and add a background color of BA to the body What s Next In the next lesson pull all the UI components and data model from Figma into the new Next js project Pull Components from Amplify ObjectivesIn this lab you will learn how to Pull components and model from AmplifyTest the componentsPulling Components from AWS AmplifyTo pull Amplify components down to the Next js application we should have the AWS Command Line Interface installed in the local machine and authorized Install the AWS CLI with the following command npm install g aws amplify cliClick on Local setup instructions copy the pull command and run it in the terminal in the Studio Next authorize the Amplify CLI and follow the prompts below to pull the components the data models the authentication and other Amplify settings AWS will add the following folders to the Next js application vscode this houses some AWS to VSCode configurationsamplify this contains AWS backend configurations models this houses the model schemasui components this is the most important for our project It includes all of our Figma designs components Next we ll import Amplify configurations and wrap the Next js application with it To do this update the app js file with the following snippets import styles globals css import Amplify from aws amplify import studioTheme from ui components import AmplifyProvider from aws amplify ui react import aws amplify ui react styles css import fontsource inter import styles reset css import awsconfig from aws exports Amplify configure awsconfig function MyApp Component pageProps return lt AmplifyProvider theme studioTheme gt lt Component pageProps gt lt AmplifyProvider gt export default MyApp In the snippets above we did the following Imported Amplify from aws amplify studioTheme from ui components and AmplifyProvider from aws amplify ui react Imported awsconfig from aws exports and used it to configure Amplify Wrapped the Components with the AmplifyProvider and passed the studioTheme as the theme prop We ve successfully connected the AWS backend environment with our Next js application To test things out let s import a component from the ui components folder in the index js file like in the below import React from react import Hero from ui components import View from aws amplify ui react function index return lt View gt lt Hero gt lt View gt export default index Here we imported the Hero component and View like a wrapper div that wraps elements Next run the following command to start the development server npm run dev to start the dev serverNext js will start a development environment at http localhost in the browser our application would look just like expected What s Next In the next lesson you ll learn how to bind data to the components Bind Data to the Components ObjectivesIn this lab you will learn how to Bind data to the componentsBind events to the componentsBinding data to ComponentsTo breathe life into the components we ll be binding data and events to them in the Amplify Studio We ll start with the Nav component Click on the UI Library tab click on the Nav and click on configure button to bind data and events to the Nav component Next in configure dialog click on the component s root Nav and click Add prop We ll create the following top level props and consume them in the elements with the Nav component username this prop will receive the user names on the website authText this prop will display the sign in or sign out buttons depending on the user authorization avatar this will handle the user avatar handleAuth this will handle the authorization event In the Nav component we want to hide the username if there s no user so select the user element and click on the Set prop button beside the child properties Select a display from the list of props click on the three vertical dots beside it click on add conditional and add conditions like in the below For the avatar text select it click on the Set text label button and set the label to the avatar and for the user name select it and set its label to the username For the button select it click on Set an onClick action select the onClick prop and set its value to handleAuth Also click on Set prop select label prop and set the value to authText For the Hero component we ll create a top level prop handleClick and set its type to an Event handler Select the Button element and set its onClick prop to the handleClick we created above We ll create two top level props for the Persuade component handleClick and banner then set their types to the Event handler and String Next select the Button element select the onClick prop and set it to the handleClick we created Select the Banner element select the src prop and set it to the banner prop we created For the Testimony component we ll bind data a bit differently unlike the earlier components we ll be binding data provisioned in our database to the Testimony component Click on the Testimony Component and click on configure select the Component s root and click on Add prop Create a top level prop testimonyModel and set its type to Testimonial data model All the elements of the Testimony Component will have access to the rows in the Testimonial table Now let s set the Testimony Component elements to different rows of the Testimonial data model Select the image element click on Set prop select the src prop and set it to testimonyModel avatar Select the Author element click on Set prop select the label prop and set it to testimonyModel name Select the Testimony text element click on Set prop select the label prop and set it to testimonyModel testimony Next click on Create collection to generate cards for the total number of records in the Testimonial data table Change the display to Grid on the collection page and set the column to three Next navigate back to UI Library let s repeat the process for the Story Component just like we did for the Testimony Component Now select the Story Component click the configure button select the Component s root and click on Add prop Create a top level prop postModel and set it to the Post data model To bind postModel data to the Story Component elements we ll select Banner element set its src prop to any static image You can choose this image Click on Set prop and set the label prop to postModel title for the title element Description element and set its text label prop to postModel description ReadTime element and set its label prop to postModel readTime also we ll concatenate a string mins read Next click the Create collection button name the collection Stories In the collection page set the display to Grid and the column to then add a padding px round the box What s Next In the next lesson you ll learn how to build the complete website using the components Build the Website pages ObjectivesIn this lab you will learn how to Use the components to build the websiteBuild the WebsiteFirst run the following command to pull the data binding changes we made into the Next js project amplify pullNext create a components folder inside it create a

following Imported the aws sdk using the require functionAdded the verify option to the bodyParser function and set it to an anonymous function Implemented the post route and did the following Created the stripeKey constant and set to the getStripeKey function Imported stripe using the Node js require function and added the stripeKey Retrieved the customer detail using the stripe instance and set the userEmail to customer email cognito called the adminCreateUser function and created the user We passed an anonymous function as a second parameter to the route When a user subscribes again we ll get an email with the user email as username and a generated temporal password Also if we inspect the Stripe webhook we will see the user details If successfully we will see the emailWhat s Next In the next lesson you ll learn how to protect the website from unauthorized customers Authenticate the Customers ObjectivesIn this lab you will learn how to Create UI for authenticationProtect the customer area from unauthorized accessAuthenticating UsersWe want to protect the post page so the only signed users can access it let s update the post js file with the following snippets pages post
