Motivation

When I first learned about QR codes, I loved the idea of using them to encode information, and was developing a few physical concept-art with QR codes. I was inspired by some of the work done by QRCode Monkey. At the time of this writing, I am ramping up on building JAMStack applications, and felt fairly confident on building a QR code generator that is 100% static and client-facing.

Following my initial desire to build something artistic with QR codes, I landed on the idea of 'graffiti with QR codes', and this kickstarted qraffiti, a creative and fun static QR code generator.

Deploy Production Build

You can build and deploy the production app by running:

git clone [email protected]:chrisrzhou/qraffiti.git
yarn
yarn build
# serve build folder

Or, you can deploy to Netlify by hitting the button below:

Developing

This project is a creative UIUX initiative around QR codes, and is considered 'done'. That being said, please feel free to submit pull requests that help improve the overall user experience of the app!

If you wish to clone and fork your own custom qraffiti generator, run the following:

git clone [email protected]:chrisrzhou/qraffiti.git
yarn
yarn dev

Adding QR Inputs, Patterns, Presets

qraffiti provides ways to set QR inputs, patterns and presets on the UI. The code affecting these are located in the /qr folder. Edit the corresponding inputs.js, patterns.js and presets.js files and changes will automatically be picked up by the UI.

Adding Logos and Backgrounds

qraffiti allows users to select provided logos and backgrounds. You can add or remove logos in the /assets folder. The GraphQL calls will naturally pick these up and include them in the app.

Areas of Improvement

• Find a way to hookup /qr folder to use GraphQL instead of constructing configurations manually.
• Renderer code for eye patterns could use more love.
• Refactor string constants to enums.
