AI Prompt setup on Nextjs.

#ai #node #nextjs #javascript

In this tutorial, we have setup our AI Prompt. Previously we did 3 parts. If you don’t know then see this link

  1. Making API Using Node and Express. Link
  2. Scaffolding redux-toolkit in NextJs. Link
  3. API Setup in NextJs. Link

Now we are doing 4th part. Let’s derive on-

Step-1 : .env file Setup and necessary package install

In your root project create .env.local file and do this

Here API key is a AI key which you get form your Ai Dashboard. https://platform.openai.com/

If you don’t have any AI API key then crate one and put in you .env.local file. And then install this package

  npm i openai@3.3.0
Enter fullscreen mode Exit fullscreen mode

Step-2 : movie Api Setup

Previously we did a movie Api setup. API Setup in NextJs.
Go to reduxStore/features/movie folder and create this file

  1. movieApi.js
  2. movieSlice.js

Image description

movieApi.js

import { apiSlice } from "../api/apiSlice";

export const moviesApi = apiSlice.injectEndpoints({
    endpoints: (builder) => ({
        topMovies: builder.query({
            query: () =>
                `/top-movies`,
        }),
        manualMovieStore: builder.mutation({
            query: (data) => ({
                url: "/movie-store",
                method: "POST",
                body: data,
            }),
        }),

        aiMovieStore: builder.mutation({

            query: (data) => ({

                url: "/ai-movie-store",
                method: "POST",
                body: data,

            }),
            async onQueryStarted(arg, { queryFulfilled, dispatch }) {
               console.log('redux', arg)
            },
        }),

    }),
});

export const { useTopMoviesQuery, useManualMovieStoreMutation, useAiMovieStoreMutation} = moviesApi;
Enter fullscreen mode Exit fullscreen mode

Here we have Three end points. There are

  1. "/top-movies"
  2. "/movie-store"
  3. "/ai-movie-store"

movieSlice.js

import { createSlice } from "@reduxjs/toolkit";

const initialState = {
    topMovies: [],
    aiMovieData:{},
    sampleData:"sdfsf sdfsf"

};

const movieSlice = createSlice({
    name: "movie",
    initialState,
    reducers: {
        topMovies: (state, action) => {
            state.topMovies = action.payload;

        },
        aiMovieData:(state, action) =>{
            console.log('redux movie')
            state.aiMovieData = action.payload;
        }

    },
});

export const { topMovies, aiMovieData} = movieSlice.actions;
export default movieSlice.reducer;
Enter fullscreen mode Exit fullscreen mode

Here we have Two actions.

  1. topMovies
  2. aiMovieData Now, movieApi.js file, we have aiMovieStore method for store Ai information in our Database. Here you saw aiMovieData action method. This action store AI information in redux store.

Step-3: Ai Movie Page Setup and Others
Go to ai-make-movie folder and see page.js file. Write this code-

import AiFormInput from "../component/ai-make-movie/AiFormInput";
import LeftSideBar from "../component/common/LeftSideBar";
import RightSideBar from "../component/common/RightSideBar";

const Page = () => {
    return (
        <div className="flex min-h-screen">
        <LeftSideBar />
        <div className=" flex-1 py-10  px-5 sm:px-10 ">
         <AiFormInput />
        </div>
        <RightSideBar />
        </div>
    );
};

export default Page;
Enter fullscreen mode Exit fullscreen mode

Now go to component/ai-make-movie and you see AiFormInput.js file

AiFormInput.js

'use client';
import { aiMovieData } from '@/app/reduxStore/features/movie/movieSlice';
import Image from 'next/image';
import { useRouter } from 'next/navigation';
import { Configuration, OpenAIApi } from 'openai';
import { useState } from "react";
import { useDispatch } from 'react-redux';
import Loading from '../../ai-make-movie/loading';

const AiFormInput = () => {
  const [aiIdea, setAiIdea] = useState();
  const dispatch = useDispatch();
  const router = useRouter();
  const [loading, setLoading] = useState(false);

  //Ai configuration
  const openAiApiKey = process.env.NEXT_PUBLIC_OPEN_AI_API_KEY;
  const configuration = new Configuration({
      apiKey: openAiApiKey
  })
  const openAi = new OpenAIApi(configuration);

  //Ai form submit handle
  const handleSubmit = async (e) => {
    e.preventDefault();
    setLoading(true);
    const aiSampleMovieData = await fetchSynopsis(aiIdea)
    dispatch(aiMovieData(aiSampleMovieData));
    //console.log('form submit', data)

   router.push("/movie-made")

  };

  async function fetchSynopsis(outline){
    const response = await openAi.createCompletion({
        model: 'text-davinci-003',
        prompt:`Generate an engaging, professional and marketable movie synopsis based on an outline. The synopsis should include actiors names in brackets after each character. Choose actors that would be ideal for this role.
        ###

        synopsis: The Top Gun Naval Fighter Weapons School is where the best of the best train to refine their elite flying skills, When hotshot fighter pilot Maverick (Tom Cruise) is sent o the school, his rackless attitude and cocky demeanor put him at odds with the other pilots, especially the cool and collected Iceman (Val kilmer). But Maverick ins't only competing to be the top fighter pilot, he's also fighting for the attention of his beautiful flight instructor, Charlotte Blackwood (kelly McGillis). Maverick gradually earns the respect of his intructors and peers - and also the love of Charlotte, but struggles to balance his personal and professional life. As the pilots prepare for a mission against a foreign enemy, Maverick must confront his own demons and overcome the tragedies rooted deep in his past to become the best fighter pilot and return from the mission triumphant.

    const synopsis = response.data.choices[0].text.trim();
    console.log('fetchSynopsis', synopsis)
    const aiMovieData = fetchTitle(synopsis);
    return aiMovieData;

export default AiFormInput;
Enter fullscreen mode Exit fullscreen mode

Here we are implement AI Prompt. Let’s do it-
If you hit this http://localhost:3000/ai-make-movie URL then you can see this page-

Image description

This page has one input field. User just type his idea and then click Make Movie button then AI generate our information. Let’s drive in our code. Here you see ** handleSubmit** method.

//Ai form submit handle
  const handleSubmit = async (e) => {
    e.preventDefault();
    setLoading(true);
    const aiSampleMovieData = await fetchSynopsis(aiIdea)
    dispatch(aiMovieData(aiSampleMovieData));
    //console.log('form submit', data)

   router.push("/movie-made")

  };
Enter fullscreen mode Exit fullscreen mode

This method Tigger when we click Make Movie button. This method first call fetchSynopsis method and passed user input idea.

async function fetchSynopsis(outline){
    const response = await openAi.createCompletion({
        model: 'text-davinci-003',
        prompt:`Generate an engaging, professional and marketable movie synopsis based on an outline. The synopsis should include actiors names in brackets after each character. Choose actors that would be ideal for this role.
        ###
        outline: A big-headed daredevil fighter pilot goes back to school only to be sent on a deadly mission.
        synopsis: The Top Gun Naval Fighter Weapons School is where the best of the best train to refine their elite flying skills, When hotshot fighter pilot Maverick (Tom Cruise) is sent o the school, his rackless attitude and cocky demeanor put him at odds with the other pilots, especially the cool and collected Iceman (Val kilmer).

Maverick gradually earns the respect of his intructors and peers - and also the love of Charlotte, but struggles to balance his personal and professional life. As the pilots prepare for a mission against a foreign enemy, Maverick must confront his own demons and overcome the tragedies rooted deep in his past to become the best fighter pilot and return from the mission triumphant.
        ###
        outline: ${outline}
        synopsis:
        `,
        max_tokens: 700
    })
    const synopsis = response.data.choices[0].text.trim();
    console.log('fetchSynopsis', synopsis)
    const aiMovieData = fetchTitle(synopsis);
    return aiMovieData;

}
Enter fullscreen mode Exit fullscreen mode

This fetchSynopsis method has dummy result, so that AI know what I need actually. Then I passed outline which I passed as aiIdea Parameter. So this method give me some result. Then I sort this result and get my Synopsis or Description. Then I call another method fetchTitle for get a catchy Title. Here I passed my synopsis result as a Parameter.

async function fetchTitle(synopsis){
    const response = await openAi.createCompletion({
        model: 'text-davinci-003',
        prompt:`Generate a catchy movie title for this synopsis: ${synopsis}`,
        max_tokens: 25,
        temperature: 0.7
    })
    const title = response.data.choices[0].text.trim();
    console.log('fetchTitle-1', synopsis)
    console.log('fetchTitle-2', title)
    const aiMovieData = fetchImagePromt(title, synopsis)
    return aiMovieData;
}
Enter fullscreen mode Exit fullscreen mode

Now this method give me Movie Title require as my synopsis. Then again I call another method fetchImagePromt for image description. Here I passed Two parameter - title and synopsis

async function fetchImagePromt(title, synopsis){
    const response = await openAi.createCompletion({
    model: 'text-davinci-003',
    prompt: `Give a short description of an image which could be used to advertise a movie based on a title and synopsis.The description should be rich in visual detail but contain no names.

    title: Love's Time Warp

    `,
    temperature: 0.8,
    max_tokens: 100

    })
    console.log('fetchImagePromt-1', synopsis)
    console.log('fetchImagePromt-2', title)
    const aiMovieData = fetchImageUrl(response.data.choices[0].text.trim(), synopsis, title)
    return aiMovieData;
}
Enter fullscreen mode Exit fullscreen mode

Here inside this method, first I setup dummy result then I setup my parameter. This method give me image description as require title and synopsis. Now I get Three result

  1. synopsis or Description
  2. title or Movie Title
  3. imagePrompt or Image Description. Now we call, another method fetchImageUrl for image create. 
async function fetchImageUrl(imagePrompt,synopsis,title){
    const response = await openAi.createImage({
        prompt: `${imagePrompt}. There should be no text in this iamge.`,
        n: 1,
        size: '256x256',
        response_format: 'b64_json'
    })
    const b64JsonImage = response.data.data[0];
    console.log('fetchImageUrl-1', synopsis)
    console.log('fetchImageUrl-2', title)
     const aiMovieData ={
        b64JsonImage,
        synopsis,
        title
    }

    return aiMovieData;
}
Enter fullscreen mode Exit fullscreen mode

This method give me Base64 image and size 256 x 256. We can increase size. Now we get three information from AI and return this information like as object to handleSubmit method

//Ai form submit handle
  const handleSubmit = async (e) => {
    e.preventDefault();
    setLoading(true);
    const aiSampleMovieData = await fetchSynopsis(aiIdea)
    dispatch(aiMovieData(aiSampleMovieData));
    //console.log('form submit', data)

   router.push("/movie-made")

  };
Enter fullscreen mode Exit fullscreen mode

Here this method got all information from AI and then dispatch this information to aiMovieData action, which we were create movieSlice.js

Image description

So, aiMovieDate method store AI information.

Image description

Now we show this information in our redux extension plugin.

Step-4: Ai Result Show and Others

Go to /movie-made folder, open page.js and do this

import AiFormResult from "../component/ai-make-movie/AiFormResult";
import LeftSideBar from "../component/common/LeftSideBar";
import RightSideBar from "../component/common/RightSideBar";

const Page = () => {
    return (
        <div className="flex min-h-screen">
        <LeftSideBar />
        <div className=" flex-1 py-10  px-5 sm:px-10 ">
          <AiFormResult />
        </div>
        <RightSideBar />
        </div>
    );
};

export default Page;
Enter fullscreen mode Exit fullscreen mode

Now go to /component/ai-make-movie folder and open AiFormResult.js and write this-

'use client';
import { useAllCategoriesQuery } from "@/app/reduxStore/features/category/categoryApi";
import { useAiMovieStoreMutation } from "@/app/reduxStore/features/movie/moviesApi";

const AiFormResult = () => {
  const [movieData, setMovieData] = useState({
    title: '',
    category_id: '',
    description: '',
    image: null, 
  });
  const aiMovieData = useSelector((state)=>state.movies.aiMovieData);
  const { data, isLoading, isError } = useAllCategoriesQuery();
  const router = useRouter()
  const [aiMovieStore, { isSuccess }] = useAiMovieStoreMutation();

  //b64_json convert image src
  const getImageSource = () => {
    const imageData = aiMovieData?.b64JsonImage?.b64_json || '';
    return `data:image/png;base64,${imageData}`;
  };


  //for category when category change.
  const handleChange = (e) => {
    const { name, value } = e.target;
    setMovieData({ ...movieData, [name]: value });
  };

  //set ai data into movieData
  useEffect(()=>{
    setMovieData({
      title: aiMovieData?.title,
      description: aiMovieData?.synopsis,
      image: aiMovieData?.b64JsonImage?.b64_json,
      });
  },[aiMovieData?.b64JsonImage?.b64_json, aiMovieData?.synopsis, aiMovieData?.title])

  const handleSubmit = async (e) => {
    e.preventDefault();
    if(movieData.category_id == ''){
      alert('please Select Category')
      return;
    }

      console.log('Response from server:-2', movieData);

    try {
      const formData = new FormData();
      formData.append('title', movieData.title);
      formData.append('category_id', movieData.category_id);
      formData.append('description', movieData.description);
      formData.append('image', movieData.image);
      console.log('form submit', movieData)
      const response = await aiMovieStore(formData);
      // Handle the success response
      console.log('Response from server:', [...formData]);
      // Assuming you want to reset the form after successful submission
      setMovieData({
        title: '',
        category_id: '',
        description: '',
        image: null,
      });
      router.push("/");
    } catch (error) {
      // Handle the error
      console.error('Error saving the movie:', error);
    }
  };

Here This page, Show AI information. If you click Save your Movie button then it Tigger aiMovieStore
Method which we were define in moviesApi.js file. This method save Ai information data in our MongoDB.

import { apiSlice } from "../api/apiSlice";

export const moviesApi = apiSlice.injectEndpoints({
    endpoints: (builder) => ({
        topMovies: builder.query({
            query: () =>
                `/top-movies`,
        }),

Setting up an AI prompt in a Next.js project involves integrating a conversational AI service. For this example, let's use OpenAI's GPT-3 API. First, ensure you have your API key from OpenAI.

Here's a step-by-step guide to setting up an AI prompt in Next.js:
If you want to learn in delta about ai toola to visit this website

Step 1: Create a Next.js Project
If you haven't already, create a Next.js project using the following commands:

npx create-next-app my-ai-project
cd my-ai-project

Step 2: Install Dependencies
Install necessary dependencies for handling HTTP requests. You can use axios in this example:

npm install axios

Step 3: Set Up an API Route
Create an API route to handle the interaction with the AI. Inside the pages/api folder, create a file, e.g., ai.js:

javascript
// pages/api/ai.js
import axios from 'axios';

export default async function handler(req, res) {
if (req.method === 'POST') {
try {
const { prompt } = req.body;

  // Replace 'YOUR_API_KEY' with your actual OpenAI API key
  const apiKey = 'YOUR_API_KEY';

  const response = await axios.post(
    'https://api.openai.com/v1/engines/davinci-codex/completions',
    {
      prompt,
      max_tokens: 100,
    },
    {
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${apiKey}`,
      },
    }
  );

  const { choices } = response.data;

  res.status(200).json({ response: choices[0].text.trim() });
} catch (error) {
  console.error(error);
  res.status(500).json({ error: 'Internal Server Error' });
}
Enter fullscreen mode Exit fullscreen mode

} else {
res.status(405).json({ error: 'Method Not Allowed' });
}
}

Step 4: Create a Component
Create a component that will allow users to interact with the AI prompt. For simplicity, let's use a basic text input:

javascript
// components/AIPrompt.js
import { useState } from 'react';
import axios from 'axios';

export default function AIPrompt() {
const [input, setInput] = useState('');
const [output, setOutput] = useState('');

const handlePrompt = async () => {
try {
const response = await axios.post('/api/ai', { prompt: input });
setOutput(response.data.response);
} catch (error) {
console.error(error);
setOutput('Error processing the prompt.');
}
};

return (


setInput(e.target.value)} />
Ask AI

AI Response: {output}


);
}

Step 5: Use the Component
In your main page (pages/index.js), import and use the AIPrompt component:

javascript
// pages/index.js
import AIPrompt from '../components/AIPrompt';

export default function Home() {
return (


Next.js AI Prompt Example




);
}

Step 6: Run Your Next.js App
Run your Next.js app with:

bash
npm run dev
Visit localhost:3000 in your browser, and you should see your AI prompt example in action.

Remember to replace 'YOUR_API_KEY' with your actual OpenAI API key. Additionally, handle security concerns such as environment variables for sensitive information.
