Integrating Python OCR Script with ReactJS

In the realm of web development, bridging the gap between backend functionalities and frontend interfaces is a common challenge. If you've ever wanted to utilize a Python script for tasks such as Optical Character Recognition (OCR) within a ReactJS application, you've landed at the right spot. In this blog, we’ll explore how to fetch an image using a Python script and share the results with a ReactJS frontend.

The Challenge

Imagine you’ve developed an OCR script using the Tesseract library in Python, as illustrated below:

Here are the key points:

Input Image Requirement: The script requires an input image named plot.png to function.

Integration with ReactJS: You want to send the image from a ReactJS component to the Python script and get the resulting text back for display or further processing.

Solution Overview

To achieve this integration, we’ll create a simple Flask server that can accept file uploads, process the image using your existing OCR script, and return the recognized text back to the ReactJS frontend.

Step 1: Set Up Flask Backend

Install Flask: Make sure you have Flask installed in your Python environment. You can install it using pip:

Create a Flask Route: Create a new route in your Flask application to handle file uploads.

Step 2: Sending Files from ReactJS

Now, let’s write the ReactJS code to send an image to this Flask server.

Add File Input in React Component: Create a function to handle the file upload.

Step 3: Connecting React and Flask

Setup Proxy: In your React app, you might want to configure the proxy in package.json to avoid any CORS issues.

Now, you can call the sendFile function upon a button click or file selection event in your React component. This will post the image to the Flask server, where it will be processed, and the recognized text will be sent back.

Conclusion

This integration setup allows you to harness the power of your Python OCR script effectively through a ReactJS interface. By following the steps laid out in this guide, you are now equipped to send an image file from ReactJS to a Flask server, process it using Tesseract OCR, and receive the extracted text for further use. Happy coding!
