Building a Flask Web App with OpenAI Integration
Flask is a popular Python web framework that allows developers to easily build web applications. OpenAI is a platform that provides powerful AI models for natural language processing, text generation, and more. In this tutorial, we will learn how to integrate OpenAI into a Flask web app to create a text generation tool.
Setting Up the Flask Environment
Before we can start integrating OpenAI into our Flask web app, we need to set up the Flask environment. Make sure you have Flask installed on your computer. You can install Flask using pip:
pip install Flask
Next, create a new Flask app by creating a new Python file. Here’s an example of a simple Flask app:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return 'Hello, World!'
if __name__ == '__main__':
app.run()
Save this code in a file named app.py. You can run your Flask app by executing the following command in your terminal:
python app.py
Integrating OpenAI into Flask
Now that we have our Flask app set up, we can start integrating OpenAI into it. First, create an account on the OpenAI platform and obtain an API key. You can find instructions on how to do this in the OpenAI documentation.
Once you have your API key, install the OpenAI Python client library using pip:
pip install openai
Now, we can use the OpenAI API in our Flask app. Here’s an example of a simple text generation endpoint using OpenAI:
import openai
openai.api_key = 'your-api-key'
@app.route('/generate-text')
def generate_text():
response = openai.Completion.create(
engine="davinci",
prompt="Once upon a time",
max_tokens=100
)
return response.choices[0].text
In this example, we are using the OpenAI API to generate text based on a prompt. The generated text is then returned as a response to the endpoint /generate-text.
Adding a Frontend to the Flask App
Now that we have our text generation endpoint set up, we can add a frontend to our Flask app to allow users to interact with the text generation tool. Create an HTML file named index.html with the following code:
Text Generation Tool
function generateText() {
fetch('/generate-text')
.then(response => response.text())
.then(data => {
document.getElementById('generated-text').textContent = data;
});
}
In this HTML file, we have a button that, when clicked, calls the generateText function to fetch text from the /generate-text endpoint and display it on the page. Save this file in the templates folder in your Flask app directory.
Running the Flask App
Finally, to run your Flask app with OpenAI integration, make sure your OpenAI API key is set up in your Flask app, and your app.py file is updated to include the text generation endpoint. Then, run your Flask app using the command:
python app.py
Open your web browser and navigate to http://localhost:5000 to see your Flask app with the text generation tool in action!
