Construct Your Personal ChatGPT Clone with React and the OpenAI API — SitePoint Acquire US

On this tutorial, we’ll stroll via learn how to construct a customized Chatbot software that can enable us to ask questions and obtain high-quality solutions. The bot will bear in mind earlier prompts, simulating context-aware dialog.

Chatbots have turn out to be indispensable instruments for companies and builders searching for to enhance buyer interactions and streamline consumer experiences in right this moment’s quickly evolving digital panorama.

OpenAI’s ChatGPT has remodeled from a cutting-edge experiment right into a powerhouse in chatbot growth. Its meteoric rise to success is nothing wanting outstanding, fascinating customers worldwide.

The demo code of this undertaking is out there on CodeSandbox. You’ll have to offer your individual OpenAI API key within the .env file to check it stay. To get one, create an account on the OpenAI, log in, navigate to the API keys and generate a brand new API key.

Planning Options and UI

Our software will likely be based mostly on React, and we’ll use OpenAI API to entry the information and use CSS modules for styling.

Using React will enable us to create a dynamic and responsive consumer interface, enhancing the general consumer expertise.

The OpenAI API will allow us to acquire entry to superior language processing capabilities, offering information for creating insightful interactions.

Moreover, CSS modules will enable us to take care of a modular design, facilitating environment friendly growth and customization of the app.

The options we’ll be implementing embrace:

  • A chosen enter space the place customers will be capable of craft prompts, inviting contextually related inquiries.
  • A Submit button that can enable customers to submit their prompts to the API, initiating the dialog course of.
  • Message objects that will likely be showcased as chat-style messages throughout the dialog window, enhancing the interactive chat expertise.
  • Message objects to show ChatGPT replies that can present a conversational circulate.
  • A Historical past function that can checklist the entire consumer’s latest prompts. This will even enable customers to revisit earlier conversations.
  • A Clear button that can enable the removing of generated content material, providing a clear slate for brand spanking new conversations.

The picture under reveals our component-based wireframe.

A wireframe of the app's interface

The entire software will likely be wrapped in the primary container, which can maintain the entire components collectively. Will probably be additional divided right into a two-column format.

The primary column will embrace the entire messages from the consumer and ChatGPT. On the backside of the column, there will likely be an enter space and a button for submitting the immediate.

The second column will maintain the historical past of the entire latest prompts. On the backside of the column, there will likely be a Clear button that can enable the consumer to wipe the generated content material.

Choosing a Shade Scheme

The appliance design will prioritize the convenience of content material notion. This can enable us to offer a few vital advantages:

  • Customers will be capable of shortly comprehend the introduced info, resulting in a extra intuitive and user-friendly expertise.
  • It is going to additionally improve accessibility, guaranteeing that people of various backgrounds and skills will be capable of simply navigate and have interaction with the content material.

The picture under reveals our coloration scheme.

Our five-color scheme: black, dark gray, lime-green, peach and white

The background of the applying will likely be black, whereas the messages, historical past objects, and enter type will likely be darkish grey.

The textual content on the messages and enter backgrounds will likely be white, offering a pleasant distinction and make textual content straightforward to learn.

To provide the app some highlights, the column titles, Submit button, and response message avatars will use a shiny, lime-green tone.

To accent the Clear button, a gentle crimson tone will likely be used. This will even assist customers keep away from clicking the button by accident.

Setting Up the React App

We’ll use create-react-app to create our software. Run npx create-react-app react-chatgpt to create a brand new React undertaking.

Watch for a minute for the setup to finish, after which change the working listing to the newly created folder by cd react-chatgpt and run npm begin to begin the developer server.

This could open up our undertaking in our default browser. If not, navigate to to open it manually. We needs to be introduced with the React welcome display, as pictured under.

React welcome screen

Including International Types

We’ll add world styling to ascertain a constant and unified visible look throughout all elements of the applying.

Open index.css and embrace the next styling guidelines:

@import url("https://fonts.googleapis.com/css2?household=Varela+Spherical&show=swap");

* 
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-family: "Varela Spherical", sans-serif;


physique 
  background-color: #121212;

First, we import the Varela Round font and set the entire app to make use of it.

We additionally take away any pre-defined margins and paddings, in addition to set box-sizing to border-box so the app appears to be like the identical on totally different browsers.

Lastly, we set the background of the physique to a darkish tone, which permits us to focus on the content material of the applying.

We’ll want a few avatars to symbolize the authors of the messages from the consumer and OpenAI API. This fashion, they’ll be simpler to differentiate.

Create a brand new icons folder contained in the src listing and embrace the bot.png and consumer.png icons.

You possibly can obtain samples from icons listing here, or you should utilize customized ones from websites like FlatIcon or Icons8, so long as you retain the above file names.

Constructing the Parts

First, we want a well-organized file construction that matches the wireframe design.

We’ll use the terminal to create the mandatory folder and element recordsdata. Every element may have its personal JavaScript file for performance and CSS file for styling.

Change the working listing within the src folder by working cd src after which run the next command:

mkdir elements && cd elements && contact Message.js Message.module.css Enter.js Enter.module.css Historical past.js Historical past.module.css Clear.js Clear.module.css

The command above will first create a /elements/ folder, then change the working listing to it, and create all the mandatory recordsdata inside it.

The Message element

The Message element will show consumer prompts and API responses throughout the dialog, facilitating the real-time alternate of knowledge between the consumer and the chatbot.

Open the Message.js file and embrace the next code:

import bot from "../icons/bot.png";
import consumer from "../icons/consumer.png";

import kinds from "./Message.module.css";

export default operate Message( position, content material ) 
  return (
    <div className=kinds.wrapper>
      <div>
        <img
          src=position === "assistant" ? bot : consumer
          className=kinds.avatar
          alt="profile avatar"
        />
      </div>
      <div>
        <p>content material</p>
      </div>
    </div>
  );

First, we import the downloaded icons for avatars after which import the exterior CSS guidelines for styling.

After that, we create the wrapper for the Message element, which can include each icons and textual content content material.

We use the position prop within the conditional to show the suitable avatar because the picture src.

We additionally use the content material prop, which will likely be handed in because the textual content response from the OpenAI API and consumer enter immediate.

Now let’s model the element so it appears to be like like a chat message! Open the Message.module.css file and embrace the next guidelines:

.wrapper 
  show: grid;
  grid-template-columns: 60px auto;
  min-height: 60px;
  padding: 20px;
  margin-bottom: 20px;
  border-radius: 10px;
  background-color: #1b1b1d;


.avatar 
  width: 40px;
  peak: 40px;

We divide the format into two columns, with the avatars proven within the fixed-width container on the suitable and the textual content on the left.

Subsequent, we add some padding and margin to the underside of the message. We additionally model the message to have spherical borders and set the background to darkish grey.

Lastly, we set the avatar icon to a hard and fast width and peak.

The Enter element

The Enter element will likely be an interface component designed to seize consumer queries, serving because the means via which customers work together and have interaction with the chatbot.

Open the Enter.js file and embrace the next code:

import kinds from "./Enter.module.css";

export default operate Enter( worth, onChange, onClick ) 
  return (
    <div className=kinds.wrapper>
      <enter
        className=kinds.textual content
        placeholder="Your immediate right here..."
        worth=worth
        onChange=onChange
      />
      <button className=kinds.btn onClick=onClick>
        Go
      </button>
    </div>
  );

We first import the exterior stylesheet to model the element.

We return the element wrapper that features the enter discipline for the consumer prompts and the button to submit it to the API.

We set the placeholder worth to be displayed when the enter type is empty, and create the worth prop to carry the entered immediate, in addition to the onChange prop that will likely be known as as soon as the enter worth modifications.

For the button, the onClick prop will likely be known as as soon as the consumer clicks on the button.

Now let’s model the element in order that the enter space appears to be like stunning and the consumer is inspired to offer prompts! Open the Enter.module.css file and embrace the next guidelines:

.wrapper 
  show: grid;
  grid-template-columns: auto 100px;
  peak: 60px;
  border-radius: 10px;
  background-color: #323236;


.textual content 
  border: none;
  define: none;
  background: none;
  padding: 20px;
  coloration: white;
  font-size: 16px;


.btn 
  border: none;
  border-radius: 0 10px 10px 0;
  font-size: 16px;
  font-weight: daring;
  background-color: rgb(218, 255, 170);


.btn:hover 
  cursor: pointer;
  background-color: rgb(200, 253, 130);

We set the wrapper to be divided into two columns, with a hard and fast width for the button and the remainder of the accessible width devoted to the enter space.

We additionally outline the particular peak of the element, set the rounded borders for it, and set the background to darkish grey.

For the enter space, we take away the default border, define, background and add some padding. We set the textual content coloration to white and set a selected font dimension.

The Historical past element

The Historical past element will show the sequence of previous consumer and chatbot interactions, offering customers with a contextual reference of their dialog.

Open the Historical past.js file and embrace the next code:

import kinds from "./Historical past.module.css";

export default operate Historical past( query, onClick ) 
  return (
    <div className=kinds.wrapper onClick=onClick>
      <p>query.substring(0, 15)...</p>
    </div>
  );

We first import the exterior model guidelines for the element. Then we return the wrapper that can embrace the textual content.

The textual content worth will likely be handed in as a query prop from the consumer immediate, and solely the primary 15 characters of the textual content string will likely be displayed.

Customers will likely be allowed to click on on the historical past objects, and we’ll move the onClick prop to regulate the clicking conduct.

Now let’s model the element to make sure it’s visually interesting and matches properly within the sidebar! Open the Historical past.module.css file and embrace the next guidelines:

.wrapper 
  padding: 20px;
  margin-bottom: 20px;
  border-radius: 10px;
  background-color: #1b1b1d;


.wrapper:hover 
  cursor: pointer;
  background-color: #323236;

We set some padding, add the margin to the underside, and set the rounded corners for the historical past objects. We additionally set the background coloration to darkish grey.

As soon as the consumer hovers over the merchandise, the cursor will change to a pointer and the background coloration will change to a lighter shade of grey.

The Clear element

The Clear element will likely be a UI component designed to reset or clear the continued dialog, offering customers with a fast option to begin a brand new interplay with out navigating away from the present interface.

Open the Clear.js file and embrace the next code:

import kinds from "./Clear.module.css";

export default operate Clear( onClick ) 
  return (
    <button className=kinds.wrapper onClick=onClick>
      Clear
    </button>
  );

We first import the exterior stylesheet to model the element.

We return the button that can enable customers to clear the content material of the applying. We’ll move the onClick prop to attain the specified conduct.

Now let’s model the element to make it stand out and cut back the possibilities of customers urgent it by accident! Open the Clear.module.css file and embrace the next guidelines:

.wrapper 
  width: 100%;
  peak: 60px;
  background-color: #ff9d84;
  border: none;
  border-radius: 10px;
  font-size: 16px;
  font-weight: daring;


.wrapper:hover 
  cursor: pointer;
  background-color: #ff886b;

We set the button to fill the accessible width of the column, set the particular peak, and set the background coloration to delicate crimson.

We additionally take away the default border, set the rounded corners, set a selected font dimension, and make it daring.

On hover, the cursor will change to a pointer and the background coloration will change to a darker shade of crimson.

Constructing the Consumer Interface

Within the earlier part, we constructed the entire essential elements. Now let’s put them collectively and construct the consumer interface for the applying.

We’ll configure their performance to create a useful and interactive chatbot interface with organized and reusable code.

Open the App.js file and embrace the next code:

import  useState  from "react";

import Message from "./elements/Message";
import Enter from "./elements/Enter";
import Historical past from "./elements/Historical past";
import Clear from "./elements/Clear";

import "./kinds.css";

export default operate App() {
  const [input, setInput] = useState("");
  const [messages, setMessages] = useState([]);
  const [history, setHistory] = useState([]);

  return (
    <div className="App">
      <div className="Column">
        <h3 className="Title">Chat Messages</h3>
        <div className="Content material">
          messages.map((el, i) => 
            return <Message key=i position=el.position content material=el.content material />;
          )
        </div>
        <Enter
          worth=enter
          onChange=(e) => setInput(e.goal.worth)
          onClick=enter ? handleSubmit : undefined
        />
      </div>
      <div className="Column">
        <h3 className="Title">Historical past</h3>
        <div className="Content material">
          historical past.map((el, i) => 
            return (
              <Historical past
                key=i
                query=el.query
                onClick=() =>
                  setMessages([
                     role: "user", content: history[i].query ,
                     position: "assistant", content material: historical past[i].reply ,
                  ])
                
              />
            );
          )
        </div>
        <Clear onClick=clear />
      </div>
    </div>
  );
}

First, we import the useState hook that we’ll use to trace the information state for the applying. Then we import all of the elements we constructed and the exterior stylesheet for styling.

Then we create the enter state variable to retailer the consumer immediate enter, messages to retailer the dialog between the consumer and ChatGPT, and historical past to retailer the historical past of consumer prompts.

We additionally create the primary wrapper for the entire app that can maintain two columns.

Every column may have a title and content material wrapper that can embrace the dialog messages, enter space, and Submit button for the primary column and historical past objects and the Clear button for the second column.

The dialog messages will likely be generated by mapping via the messages state variable and the historical past objects — by mapping via the historical past state variable.

We set the enter onChange prop to replace the enter state variable every time consumer enters any worth within the enter type.

As soon as the consumer clicks the Ship button, the consumer immediate will likely be despatched to the OpenAI API to course of and obtain the reply.

For the historical past objects, we set the onClick prop in order that the messages state variable will get up to date to the particular immediate and reply.

Lastly, for the Clear button, we move the onClick prop a operate that can clear each the message and historical past values, clearing the applying information.

Creating the App Structure

On this part, we’ll prepare the consumer interface elements to create an intuitive construction for efficient consumer interplay.

Open App.css and embrace the next styling guidelines:

.App 
  show: grid;
  grid-template-columns: auto 200px;
  hole: 20px;
  max-width: 1000px;
  margin: 0 auto;
  min-height: 100vh;
  padding: 20px;


.Column 
  coloration: white;


.Title 
  padding: 20px;
  margin-bottom: 20px;
  border-radius: 10px;
  coloration: black;
  background-color: rgb(218, 255, 170);


.Content material 
  peak: calc(100vh - 200px);
  overflow-y: scroll;
  margin-bottom: 20px;


::-webkit-scrollbar 
  show: none;

We cut up the primary app wrapper into two columns, separated by a niche by utilizing CSS grid format, and we set the left column for historical past objects to a hard and fast width.

Subsequent, we set the wrapper to by no means exceed a sure width, middle it on the display, make it use the entire display viewport peak, and add some padding inside it.

For every column’s contents, we set the textual content coloration to white.

For the column titles, we set some padding, add the underside margin, and set the rounded corners. We additionally set the title component background coloration to lime-green and set the textual content coloration to black.

We additionally model the columns themselves by setting the rule that the content material shouldn’t exceed a sure peak and set the content material to be scrollable if it reaches exterior the peak. We additionally add a margin to the underside.

We additionally conceal the scrollbars, in order that we don’t should model them to override the default values for every browser. This rule is non-compulsory and we might go away it out.

Getting the API Key from OpenAI

In case you haven’t already arrange your individual API key for the Sandbox within the introduction of this tutorial, be sure to create an account on the OpenAI web site.

Subsequent, log in and navigate to the API keys and generate a brand new API key.

setting up an api key

Copy the important thing to the clipboard and open your undertaking.

Create a brand new .env file in your undertaking root and paste the worth for the next key like so:

REACT_APP_OPENAI_API_KEY=paste-your-code-here

Making ready the Request Name to OpenAI API

By the OpenAI API, our chatbot will be capable of ship textual prompts to the OpenAI server, which can then course of the enter and generate human-like responses.

That is achieved by leveraging a robust language mannequin that’s been skilled on numerous textual content sources. By offering the mannequin with a dialog historical past and the present consumer immediate, our chatbot will obtain context-aware responses from the API.

On this part, we’ll put together the request and implement the decision to the API to obtain the response and set the information to the state variable we outlined earlier.

Open the App.js once more and add the next code:



export default operate App() {
  

  const handleSubmit = async () => 
    const immediate = 
      position: "consumer",
      content material: enter,
    ;

    setMessages([...messages, prompt]);

    await fetch("https://api.openai.com/v1/chat/completions", 
      technique: "POST",
      headers: 
        Authorization: `Bearer $course of.env.REACT_APP_OPENAI_API_KEY`,
        "Content material-Kind": "software/json",
      ,
      physique: JSON.stringify(
        mannequin: "gpt-3.5-turbo",
        messages: [...messages, prompt],
      ),
    )
      .then((information) => information.json())
      .then((information) => 
        const res = information.decisions[0].message.content material;
        setMessages((messages) => [
          ...messages,
          
            role: "assistant",
            content: res,
          ,
        ]);
        setHistory((historical past) => [...history,  question: input, answer: res ]);
        setInput("");
      );
  ;

  const clear = () => 
    setMessages([]);
    setHistory([]);
  ;

  return <div className="App">
}

First, we create a separate handleSubmit operate, which will likely be executed as soon as the consumer has entered the immediate within the enter type and clicks the Submit button.

Inside handleSubmit, we first create the immediate variable that can maintain the position consumer and the immediate itself as an object. The position is vital as a result of, when storing our messages, we’ll must know which of them are consumer messages.

Then we replace the messages state variable with the consumer immediate.

Subsequent, we make an precise fetch name to the api.openai.com/v1/chat/completions endpoint to entry the information from the OpenAI API.

We specify that it’s a POST request, and set the headers with the authorization token and the content material kind. For the physique parameters, we specify which API mannequin to make use of, and we move the messages variable because the content material from the consumer.

As soon as the response is acquired, we retailer it within the res variable. We add the item consisting of the position assistant and the response itself to the message state variable.

We additionally replace the historical past state variable with the item, with the query and corresponding reply because the keys.

After the response is acquired and state variables are up to date, we clear the enter state variable to organize the enter type for the subsequent consumer immediate.

Lastly, we create a easy clear operate to clear the messages and historical past state variables, permitting the consumer to clear the information of the applying.

Testing the Software

At this level, we must always have created a completely useful chat software! The very last thing left to do is to check it.

First, let’s attempt to ask ChatGPT a single query.

A question asked via our new app

The animation above reveals a query being submitted and a solution being acquired.

Now let’s attempt to create a dialog.

Submitting multiple questions

As proven within the animation above, the chatbot remembers the context from the earlier messages, so we are able to communicate with it whereas being totally context-aware.

Now let’s see what occurs as soon as we click on on the Historical past button.

Clicking on the History button

Discover how the chat switches to the respective consumer immediate and reply. This may very well be helpful if we wish to resume the dialog from a selected level.

Lastly, let’s click on on the Clear button.

Clicking on the Clear button

As anticipated, the contents of the app are cleared. It is a helpful possibility when there’s loads of content material and the consumer needs to begin recent.

Conclusion

On this tutorial, we’ve realized learn how to create an easy-to-use consumer interface, learn how to construction our code through elements, learn how to work with states, learn how to make API calls, and learn how to course of the acquired information.

With the mixture of superior pure language processing capabilities of the OpenIAI API and the flexibleness of React, you’ll now be capable of create subtle chatbot functions that you would be able to customise additional to your liking.

Discover that this tutorial shops the API key on the frontend, which could not be safe for manufacturing. If you wish to deploy the undertaking, it might be advisable to create an Express server and use the API key there.

Additionally, if you’d like the historical past prompts to be accessible after the subsequent preliminary launch, you could possibly retailer after which learn them from native storage, and even join a database to your app and retailer and browse information from there.
