Plate Check

I developed Plate Check as my final project at SPICED Academy Berlin. Plate Check is a React app I built for a friend of mine who's recently been diagnosed with IBS. With this app she can scan the barcode of a product and get the result that says weather the product is safe for her consumption or not.

The app works with QuaggaJS, a barcode-scanner entirely written in JavaScript supporting real- time localization and decoding of various types of barcodes such as EAN, CODE 128, CODE 39, EAN 8, UPC-A, UPC-C, I2of5, 2of5, CODE 93 and CODABAR. When Quagga returns a result, a 10 digits number is then being compared against a list of unique product ID's contained in a MongoDB. Once there is a hit, a final comparison is being made against a list of ingredients to be avoided, contained in another, this time postgreSQL database. The app wil then return one of the three results:

• the product is safe for consumption
• the product should be avoided
• not enough info on the product
