feat: add translation module for labels #11
Conversation
WalkthroughThis pull request adds translation support to the osmosys-form component. It introduces the "@ngx-translate/core" dependency in package.json. The HTML template is updated to wrap user-facing texts (labels, placeholders, validation messages, and options) with translation function calls. In the TypeScript file, two new input properties (useTranslation and translateService) and a new translate(key: string) method are added to conditionally apply translations based on user configuration.

60-68: Add TranslateService validation in ngOnInit.When translation is enabled, the component should validate that TranslateService is properly provided.
Add this validation to ngOnInit:
ngOnInit(): void { + if (this.useTranslation && !this.translateService) { + console.error('TranslateService is required when useTranslation is enabled'); + } + this.formConfig = this.formJsonData || {}; if (this.formConfig.layout?.rows) { this.createForm(this.formConfig.layout.rows); } this.formInstance.emit(this.form); }

39-39: Consider security implications of autocomplete attribute.The autocomplete attribute has been added with a default of 'off' for all form elements. While this enhances security, it might affect user experience for non-sensitive fields.
Consider making the autocomplete value configurable through the form configuration:
-[autocomplete]="element.autocomplete || 'off'" +[autocomplete]="element.autocomplete || element.type === 'password' ? 'off' : 'on'"Also applies to: 75-75, 123-123, 163-163, 198-198, 233-233, 286-286, 327-327, 368-368, 409-409
39-39: Enhance autocomplete attributes with semantic values.While setting autocomplete to 'off' by default is a good start, consider using semantic values for better user experience.
For example:
-[autocomplete]="element.autocomplete || 'off'" +[autocomplete]="element.autocomplete || getDefaultAutocomplete(element.type, element.name)"Add this helper method to the component:
private getDefaultAutocomplete(type: string, name: string): string { switch (type) { case 'input': if (name.includes('email')) return 'email'; if (name.includes('phone')) return 'tel'; if (name.includes('name')) return 'name'; return 'off'; case 'password': return 'new-password'; default: return 'off'; } }Also applies to: 75-75, 123-123, 163-163, 198-198, 233-233, 286-286, 327-327, 368-368, 409-409

188-200: Add type safety and null checks to the translate method.While the implementation is functional, it could benefit from improved type safety and null handling.
Consider this enhanced implementation:
- translate(key: string): string { + translate(key: string | null | undefined): string { + if (!key) { + console.warn('Translation key is empty'); + return ''; + } + if (this.useTranslation && this.translateService) { - if (key) { - return this.translateService.instant(key) || key; - } - - // eslint-disable-next-line no-console - console.warn(`Translation key is empty: ${key}`); - return ''; // Return an empty string if the key is invalid + const translated = this.translateService.instant(key); + return translated || key; } return key; // Return the key as fallback if translation is not used }

22-22: LGTM! The translation service integration looks good.The implementation correctly imports TranslateService and adds input properties with appropriate defaults for backward compatibility.
Also applies to: 38-40
188-200: Consider adding unit tests for the translate method.The translate method implementation looks good with proper null checks and fallback handling. However, it's missing unit tests to verify the behavior.
Would you like me to generate unit tests for the translate method to cover:
- Translation with valid key
- Translation with empty key
- Translation when service is not provided
- Translation when useTranslation is false
22-22: LGTM! Translation service integration looks good.The TranslateService import and input properties are properly defined with good defaults for backward compatibility.

24-24: Verify compatibility between Angular 18 and ngx-translate 15.The project uses Angular 18, but @ngx-translate/core is pinned to version 15. Let's verify if this version is compatible with Angular 18.

Usage guide:
Users must have translation support set up in their application where they are using the osmosys-forms component. This includes configuring the ngx-translate service and defining translation files with appropriate keys and values.
Users can enable translation by passing the useTranslation flag as true and providing the translation service to the osmosys-forms component.
