Open your terminal and run the following command: curl -I The output should look like this: We can test it in many ways, such as with Postman or Thunder Client, but I will use a curl request. Let’s test our server by hitting the test route that we previously configured. To run the server, first add the following code in the scripts objects located in package.json: "start": "nodemon index.js", QRCode.toFile('/output-file-path/file.png', 'Encode this text in QR code'. Here is an example of how to use the toFile method to generate a QR code image file: // _ Importing qrcode _ \\ This method takes a file path, the text to encode in the QR code, and an options object as arguments, and generates a QR code image file at the specified file path.

Installing the qrcode-reader and jimp libraries.In this article, we will go over the steps for reading and writing QR codes in Node using three popular libraries: qrcode-reader and jimp for reading QR codes, and qrcode for generating QR codes. Reading and writing QR codes can easily be done with Node.js, the popular JavaScript runtime environment. QR codes are a convenient and efficient way to store and share information. ![]()
