"Transform server-side to client-side with React"

To transform a server-side component into a client-side one, use "use client" on top when utilizing state or hooks like "use state" in React.
State management in React primarily occurs on the client side, where component state is managed and updated within the browser.
Use "use client" with React hooks like "use state" or "use effect" to prevent errors.
Server components are recommended by default until a need for client components arises, as per Next.js documentation.
Use server-side components for fetching data like articles, blog posts, or website data, and for accessing backend resources directly.
Use client-side components for interactivity, event listeners, state management, lifecycle effects, custom hooks, or React class components.
Next.js simplifies routing by creating folders corresponding to desired routes within the app directory.
Nested routing in Next.js involves nesting folders to create routes, simplifying the process compared to React without Next.js.
Dynamic routing in Next.js allows for flexible page creation based on variables or data, using square brackets for dynamic IDs.
Next.js allows for the creation of layout and loading files within subfolders to share UI components and handle errors gracefully.

Creating Next.js API with Primetopia features

To create an endpoint in Nexjs with similar functionality to Express, export an async function named "get" to retrieve users and return them.
Nexjs simplifies API creation by handling details like Express configuration, allowing focus on specific endpoint needs and business logic.
To access the specific API in the browser, navigate to "localhost:3000/API/users" within the app's API users route.
Nexjs introduces a new metadata API offering static and dynamic metadata management for SEO improvement.
For static metadata modification, export a metadata object with a title from the file exporting the specific page or route.
Dynamic metadata involves an async function to generate metadata based on dynamic parameters like a product ID.
The project "Primetopia" is an open-source AI prompting tool for creating and sharing creative prompts using Chat GPT.
Features of Primetopia include Google authentication, browsing prompts by tags, usernames, and content, and CRUD functionality.
To start building a modern Next.js application, create a new folder named "primetopia" and install dependencies like bcrypt, mongodb, Mongoose, and next-auth.
Develop the project structure with folders for components, models, public, styles, utils, and an .env file, and add assets and styles for the application.

"Next.js: Importing Components and Navigation Setup"

To import the feed component, use "import feed from add components/feed" in Next.js.
Call the self-closing feed component to render the word "feed."
Move on to the layout JSX to include the navigation bar, ensuring its reuse across all pages.
Import "nav" and "provider" from add components/nav and add components/provider respectively.
Import "link" and "image" from next/link and next/image to enable navigation and image optimization.
Import hooks "useState" and "useEffect" from React for functional components.
Import "signIn," "signOut," "useSession," and "getProviders" from next-auth/react for authentication.
Create the structure of the navigation bar by modifying a div into a semantic nav tag with specific class names and elements.
Develop the mobile navigation by setting up conditional rendering based on user login status and adding buttons for actions like creating a post and signing out.
Implement a dropdown menu for mobile navigation by toggling a state and rendering links and buttons accordingly.

Next Auth Google Authentication Setup

To implement authentication, the provider component needs to be wrapped around the body in the app.
Next auth requires both front-end files and next GS API backend endpoints for authentication.
Create a new folder named API within the app and then a folder named auth within it.
Within the auth folder, create a folder named [next auth] and a route.js file.
Import next auth and Google provider from next-auth/providers/Google to handle authentication.
Create a Handler function using next auth, specifying Google provider with client ID and client secret.
Export Handler as get and post for next authentication setup.
Obtain Google credentials from console.cloud.google.com and add them to the .env file.
Connect to the MongoDB database using Mongoose and create a user model in the models directory.
Implement sign-in function to check for existing users, create new users, and update user session data.

Enhance Appearance and Create New Prompts

Use font Dash semi bold text Dash base and text Dash gray-700 to enhance appearance
Add a text area labeled "text area" with value as post dot prompt and on change callback function to update post
Include a placeholder "write your prompt here" and a class name "form underscore text area" for styling
Duplicate the label for prompt field or tag, using an input instead of text area, with value as post dot tag
Create a cancel button with a link saying "cancel" and a button for submission with type "submit" and disabled property
Style the button with padding, background color, and text color for a call to action appearance

Create a new prompt route in the API folder with a post request to save the prompt data to the database
Define a prompt schema in the models folder to structure the prompt data in the database
Import the prompt model in the new prompt route to create and save a new prompt, returning a response with the new prompt data if successful

Creating Interactive Feed with Prompt Cards

The prompt card component is sourced from dot slash prompt card.
The JSX part of the feed is initiated by creating a section with a class name "feed" containing a form for feed search.
The form includes a self-closing input tag with type "text" and a placeholder for search, linked to a state "search text" and an "on change" function "handle search change."
To resolve the error of undeclared state, a new state "search text" is created using the useState hook.
A function "handle search change" is declared to manage search input changes.
The prompts are rendered using a component called "prompt card list," accepting data and a handle tag click function.
Data for the prompt card list is fetched from a GET request to the nextgs API endpoint "/API/prompt" using the useEffect hook.
The API endpoint "/API/prompt" is created to fetch all prompts and return them as JSON data.
The fetched posts are passed to the prompt card list component for rendering.
The prompt card component is structured to display the prompt, creator's image, username, email, copy button, prompt content, and tags, with functionality to copy prompts to the clipboard.
