refactor: ts integration in restrictedElementDiv #471
Conversation
WalkthroughThis pull request removes the JavaScript module managing restricted elements and replaces it with a TypeScript version. The new TypeScript module reimplements functions to update, display, and toggle the visibility of restricted elements while integrating a global scope. Additionally, a new interface defining the structure for the scope has been introduced. These changes ensure type safety in the simulator's user interface components and align with the ongoing migration effort in the Changes

src/simulator/src/types/restrictedElementDiv.types.ts (1)
1-4: Consider enhancing type safety with readonly modifiers and more specific types.The interface looks good but could be improved with:
- Readonly modifiers to prevent accidental mutations
- More specific types for the index signature to better represent valid keys
export interface Scope { - [key: string]: string[]; - restrictedCircuitElementsUsed: string[]; + readonly [key: string]: readonly string[]; + readonly restrictedCircuitElementsUsed: readonly string[]; }src/simulator/src/restrictedElementDiv.ts (3)
30-42: Improve functional style and avoid direct mutations.
- Early return logic should check scope
- Use functional array methods instead of forEach
- Consider returning new scope instead of mutating
export function updateRestrictedElementsInScope(scope: Scope = globalScope): void { - if (restrictedElements.length === 0) return; + if (!scope || Object.keys(scope).length === 0) return; - const restrictedElementsUsed: string[] = []; - restrictedElements.forEach((element: string) => { - if (scope[element] && scope[element].length > 0) { - restrictedElementsUsed.push(element); - } - }); + const restrictedElementsUsed = restrictedElements.filter( + element => scope[element]?.length > 0 + ); scope.restrictedCircuitElementsUsed = restrictedElementsUsed; updateRestrictedElementsList(); }
61-66: Add error handling for consistency with showRestricted.The function should handle the case when the element is not found.
export function hideRestricted(): void { const restrictedDiv = document.getElementById('restrictedDiv'); - if (restrictedDiv) { - restrictedDiv.classList.add('display--none'); + if (!restrictedDiv) { + console.error('Element restrictedDiv not found'); + return; } + restrictedDiv.classList.add('display--none'); }
1-66: Consider architectural improvements for better maintainability and testability.
- Abstract DOM manipulation into a separate service
- Implement proper state management (e.g., using a store pattern)
- Add interfaces for DOM operations to facilitate testing
- Add unit tests for the business logic
Would you like me to provide an example of how to restructure this code with better architecture?

1-6: LGTM! Good use of TypeScript type annotations.The code follows TypeScript best practices by properly importing and using the
Scopeinterface, and declaring variables with appropriate type annotations.
3-6: Consider makingrestrictedElementsreadonly for improved type safety.Since
restrictedElementsappears to be a constant configuration that shouldn't be modified after initialization, consider making it readonly for better type safety.-const restrictedElements: string[] = []; +const restrictedElements: readonly string[] = [];
8-24: Efficient implementation with proper error handling.The function now uses the efficient
joinmethod instead of string concatenation in a loop, includes proper checking for empty arrays, and handles potential DOM element absence correctly.
40-53: Well-structured restricted message display with proper error handling.The function now defines a constant message, checks for the existence of DOM elements before manipulation, and includes appropriate error handling.
1-60:✅ Verification successful
Verify if the Scope interface correctly supports index access.
The code uses index access on the
Scopeinterface (e.g.,scope[element]). Ensure that theScopeinterface properly supports this type of access.
🏁 Script executed:
#!/bin/bash # Check the definition of the Scope interface fd "restrictedElementDiv.types.ts" --type f | xargs catLength of output: 157
Index Access Verified:
TheScopeinterface correctly supports index access as it includes the index signature[key: string]: string[];. The verification confirms that accessing properties likescope[element]is valid. No further changes are required.

🛠️ Refactor suggestion
Improve type safety for scope indexing operation.
The code accesses scope[element] as an index, but the TypeScript interface for Scope might not explicitly support this operation, which could lead to type errors.
import { Scope } from './types/restrictedElementDiv.types'
+// Type guard to check if an element exists in scope with valid length
+function isValidElement(scope: Scope, element: string): boolean {
+ return element in scope &&
+ Array.isArray(scope[element as keyof Scope]) &&
+ (scope[element as keyof Scope] as unknown as any[]).length > 0;
+}
export function updateRestrictedElementsInScope(scope: Scope = globalScope): void {
if (restrictedElements.length === 0) return;
const restrictedElementsUsed: string[] = [];
restrictedElements.forEach((element: string) => {
- if (scope[element] && scope[element].length > 0) {
+ if (isValidElement(scope, element)) {
restrictedElementsUsed.push(element);
}
});
scope.restrictedCircuitElementsUsed = restrictedElementsUsed;
updateRestrictedElementsList();
