Automating Token Updates and Auditing

1. Introduction

Automating token updates and auditing is crucial for maintaining design consistency across applications. Design tokens serve as a bridge between design and development, allowing teams to manage design attributes such as colors, typography, spacing, and more in a centralized manner. This lesson will guide you through the process of automating updates and auditing for design tokens.

3. Step-by-Step Process

1. Set Up a Token Format: Determine a format for your tokens, such as JSON or YAML.

   {
       "colors": {
           "primary": "#ff5733",
           "secondary": "#33c1ff"
       },
       "fontSizes": {
           "small": "12px",
           "medium": "16px",
           "large": "20px"
       }
   }

2. Create Automation Scripts: Use tools like Node.js or Python to create scripts that will update token values. For example, using Node.js:

   const fs = require('fs');
   const tokens = require('./tokens.json');
   
   tokens.colors.primary = '#ff5733'; // Update token
   
   fs.writeFileSync('./tokens.json', JSON.stringify(tokens, null, 2));

3. Implement CI/CD Pipelines: Integrate your automation scripts into CI/CD pipelines to trigger updates on code changes.
4. Set Up Auditing Tools: Use tools like Stylelint or custom scripts to audit tokens for consistency. An example audit script could look like this:

   const tokens = require('./tokens.json');
   
   if (!tokens.colors.primary.match(/^#[0-9A-F]{6}$/i)) {
       console.error('Invalid primary color token!');
   }

4. Best Practices

• Maintain a clear naming convention for your tokens.
• Regularly review and update your token values.
• Ensure that your automation scripts are tested before deployment.
• Use version control to track changes in your token files.
• Document your token structure and updates for team awareness.
