In this tutorial, we will walk through the process of building a content generator using OpenAI Codex and React. OpenAI Codex is a powerful language model that can generate human-like text given certain prompts. React, on the other hand, is a popular JavaScript library for building user interfaces. By combining the two, we can create a dynamic content generator for various applications such as chatbots, documentation, or content generation tools.<\/p>\n
To get started, make sure you have the following installed:<\/p>\n
If you don’t have these installed, you can download and install them from their official websites.<\/p>\n
mkdir content-generator\ncd content-generator\n<\/code><\/pre>\n\n- Initialize a new React project using create-react-app.<\/li>\n<\/ol>\n
npx create-react-app .\n<\/code><\/pre>\nThis command creates a new React project in the current directory.<\/p>\n
\n- Start the development server to ensure everything is set up correctly.<\/li>\n<\/ol>\n
npm start\n<\/code><\/pre>\nIf everything is set up correctly, you should see a new browser window open with the React app running.<\/p>\n
Installing OpenAI Codex<\/h2>\n\n- OpenAI Codex requires an API key to access its services. Visit the OpenAI website and create a new account if you haven’t already.<\/p>\n<\/li>\n
- \n
Once you have created an account, follow the instructions to obtain an API key.<\/p>\n<\/li>\n
- \n
After obtaining the API key, create a new file in the root directory of your project called .env<\/code>. Inside this file, add the following line:<\/p>\n<\/li>\n<\/ol>\nREACT_APP_OPENAI_API_KEY=<your_openai_api_key>\n<\/code><\/pre>\nReplace <your_openai_api_key><\/code> with the API key you obtained earlier. This environment variable will allow your React app to access the OpenAI Codex API.<\/p>\n\n- Install the
openai<\/code> package using npm.<\/li>\n<\/ol>\nnpm install openai --save\n<\/code><\/pre>\nThis package allows us to interact with the OpenAI Codex API from our React app.<\/p>\n
\n- Create a new file called
openai.js<\/code> in the src<\/code> directory. This file will contain the code to interact with the OpenAI Codex API.<\/p>\n<\/li>\n- \n
In the openai.js<\/code> file, add the following code:<\/p>\n<\/li>\n<\/ol>\nimport openai from 'openai';\n\nconst openaiApiKey = process.env.REACT_APP_OPENAI_API_KEY;\nconst openaiInstance = new openai.OpenAI(openaiApiKey);\n\nexport default openaiInstance;\n<\/code><\/pre>\nThe code imports the openai<\/code> package, assigns the API key to openaiApiKey<\/code>, and creates a new instance of the openai.OpenAI<\/code> class using the API key.<\/p>\n\n- In the
App.js<\/code> file, import the openai.js<\/code> file using the following code at the top of the file:<\/li>\n<\/ol>\nimport openaiInstance from '.\/openai';\n<\/code><\/pre>\nCreating the Content Generator Component<\/h2>\n\n- Create a new file called
ContentGenerator.js<\/code> in the src<\/code> directory.<\/p>\n<\/li>\n- \n
In the ContentGenerator.js<\/code> file, add the following code:<\/p>\n<\/li>\n<\/ol>\nimport React, { useState } from 'react';\nimport openaiInstance from '.\/openai';\n\nfunction ContentGenerator() {\n const [prompt, setPrompt] = useState('');\n const [content, setContent] = useState('');\n\n const handleChange = (event) => {\n setPrompt(event.target.value);\n };\n\n const handleSubmit = async (event) => {\n event.preventDefault();\n\n try {\n const response = await openaiInstance.complete({\n engine: 'text-davinci-003',\n prompt,\n maxTokens: 200,\n temperature: 0.7,\n });\n\n setContent(response.choices[0].text);\n } catch (error) {\n console.log(error);\n }\n };\n\n return (\n <div>\n <form onSubmit={handleSubmit}>\n <label>\n Enter Prompt:\n <input type=\"text\" value={prompt} onChange={handleChange} \/>\n <\/label>\n <button type=\"submit\">Generate<\/button>\n <\/form>\n\n <div>\n <h2>Generated Content:<\/h2>\n <p>{content}<\/p>\n <\/div>\n <\/div>\n );\n}\n\nexport default ContentGenerator;\n<\/code><\/pre>\nThe code sets up a functional React component called ContentGenerator<\/code>. It includes state for the prompt<\/code> and content<\/code> values.<\/p>\nThe handleChange<\/code> function sets the prompt<\/code> state whenever the input value changes.<\/p>\nThe handleSubmit<\/code> function is triggered when the form is submitted. It makes an asynchronous call to the OpenAI Codex API using the openaiInstance<\/code> initialized earlier with the provided prompt as input.<\/p>\nThe response from the API is stored in the content<\/code> state, and any error is logged to the console.<\/p>\nThe component renders a form with an input field for the prompt and a “Generate” button. The generated content is displayed below the form.<\/p>\n
\n- Import and use the
ContentGenerator<\/code> component in the App.js<\/code> file:<\/li>\n<\/ol>\nimport ContentGenerator from '.\/ContentGenerator';\n\nfunction App() {\n return (\n <div className=\"App\">\n <h1>Content Generator<\/h1>\n <ContentGenerator \/>\n <\/div>\n );\n}\n\nexport default App;\n<\/code><\/pre>\n\n- Save your changes and go back to the terminal or command prompt. You should see the generated content displayed on the screen when you enter a prompt and click the “Generate” button.<\/li>\n<\/ol>\n
Styling the Content Generator<\/h2>\n\n- Open the
src\/App.css<\/code> file and add the following CSS code to style the content generator:<\/li>\n<\/ol>\n.App {\n text-align: center;\n}\n\nform {\n margin-bottom: 20px;\n}\n\ninput {\n margin-left: 10px;\n}\n\nbutton {\n margin-left: 10px;\n}\n\n.generated-content {\n margin-top: 20px;\n border: 1px solid #ccc;\n border-radius: 5px;\n padding: 10px;\n background-color: #f5f7fa;\n}\n<\/code><\/pre>\n\n- In the
ContentGenerator<\/code> component, add the generated-content<\/code> class to the wrapper <div><\/code> element surrounding the generated content:<\/li>\n<\/ol>\n<div className=\"generated-content\">\n <h2>Generated Content:<\/h2>\n <p>{content}<\/p>\n<\/div>\n<\/code><\/pre>\n\n- Save your changes and go back to the browser. You should see the content generator styled with a border and background color.<\/li>\n<\/ol>\n
Deploying the Application (Optional)<\/h2>\n
If you want to deploy your application to a web server or static hosting service, you can follow these steps:<\/p>\n
