Angular i18n Refactoring Skill (Namespaced)

Use this skill to systematically refactor Angular components for internationalization (ngx-translate) using a nested JSON structure (Namespaces).

workflow

1. Scan and Extract

• Analyze the user-selected HTML file.
• Determine the Namespace based on the component name (e.g., UserProfileComponent -> USER_PROFILE).
• Identify all hardcoded text nodes and static attributes (specifically placeholder, title, alt, aria-label).
• Generate keys nested under the namespace in UPPER_SNAKE_CASE (e.g., Namespace: USER_PROFILE, Key: SUBMIT_BTN).

2. Template Refactoring (HTML)

• Replace text content with the pipe syntax using dot notation: {{ 'NAMESPACE.KEY' | translate }}.
  • Example: {{ 'USER_PROFILE.SUBMIT_BTN' | translate }}
• Replace attributes with bound syntax: [placeholder]="'NAMESPACE.KEY' | translate".

3. Component Dependency Injection (TS)

• Locate the corresponding .ts file.
• Check Imports: Ensure import { TranslateService } from '@ngx-translate/core'; exists.
• Check Injection: Verify if TranslateService is injected.
  • If missing, add: private translate = inject(TranslateService); (Use constructor injection for older Angular versions).

4. Translation Generation (JSON)

• Locate src/assets/i18n/en.json and src/assets/i18n/tc.json.
• Structure: Create or update the JSON with nested objects, not flat keys. Example Structure: "USER_PROFILE": { "SUBMIT_BTN": "Submit", "CANCEL_BTN": "Cancel" }
• English (en.json): Add the nested keys with original text.
• Traditional Chinese (tc.json): Auto-translate text to Traditional Chinese (Hong Kong style, zh-HK) and maintain the same nested structure.

5. Final Reporting

• Output a markdown table summary of the changes:

Guidelines

• Strictly maintain JSON nesting. Do not create keys like "USER_PROFILE.SUBMIT_BTN": "...". It must be "USER_PROFILE": { "SUBMIT_BTN": "..." }.
• Prioritize "Hong Kong" terminology for tc.json (e.g., use "登入" for Login, not "登錄").
• If the translation files are not in context, ask the user for their location.
