Create Custom PWA Icons

• Font size: 50
• Color: #FFFFFF
• Background: #006747

Download and save favicon_io.zip file to images folder. Extract and delete the zipfile.

Copy favicon.ico into the root project folder (the one that has the index.html file).

Second, create a full set of PWA icons

Full set of PWA icons built with PWA Builder App Image Generator. Upload your largest favicon (e.g., the 512 size created above) and update settings as desired (these used 0.3 padding with custom color #006747). Check all the boxes. Click the button below the color option to generate a zipfile. Save the AppImages.zip file to images folder. Extract and delete the zipfile.

Update icons property in manifest.json as needed (if the names are the same, updates can be copied from a reference project).

Third, create additional Android icons (optional)

• Android Asset Studio

npm run sort
npm install
npm run prettier
npm run lint
npm run lint-fix
