33-33:⚠️ Potential issueUpdate JSDoc return type to match implementation
The JSDoc comment specifies a return type of
Promise<T | void>, but the actual implementation now returnsPromise<T | string>. This mismatch could lead to confusion for developers.- @returns {Promise<T | void>} Returns the data stored in local storage or undefined if no data is found + @returns {Promise<T | string>} Returns the data stored in local storage or a message string if operation was successful or an error occurred
49-49: 🛠️ Refactor suggestionConsider returning structured error responses instead of plain strings
The function now returns string messages in several places, which makes error handling more difficult for consumers of this API. They would need to check if the return value is a string to determine if an error occurred.
Consider returning structured responses that clearly indicate success/failure:
export async function lscStorage<T extends Record<string, any>>(key: string, value?: T): Promise<{data: T | null, success: boolean, message: string}> { try { if (value !== undefined) { localStorage.setItem(key, JSON.stringify(value)); - return `${key} stored in local storage!`; + return {data: null, success: true, message: `${key} stored in local storage!`}; } else { const data = localStorage.getItem(key); if (data) { try { - return JSON.parse(data) as T; + return {data: JSON.parse(data) as T, success: true, message: ""}; } catch (error) { console.error("Failed to parse the data from local storage", error); - return "Failed to parse the data from local storage"; + return {data: null, success: false, message: "Failed to parse the data from local storage"}; } } - return "No data found in local storage"; + return {data: null, success: false, message: "No data found in local storage"}; } } catch (error) { if (error instanceof DOMException && error.name === "QuotaExceededError") { console.log("Storage is full, please clear some space!"); } else { console.error("Error accessing local storage", error); } - return "Error accessing local storage"; + return {data: null, success: false, message: "Error accessing local storage"}; } }Also applies to: 57-58, 60-60, 68-69
13-13:⚠️ Potential issueUpdate overload signatures to match the implementation
The function overload signatures on lines 13 and 26 no longer match the actual implementation. These should be updated to reflect the new return type.
- export async function lscStorage<T extends Record<string, any>>(key: string, value: T): Promise<void>; + export async function lscStorage<T extends Record<string, any>>(key: string, value: T): Promise<string>; - export async function lscStorage<T extends Record<string, any>>(key: string): Promise<T | null>; + export async function lscStorage<T extends Record<string, any>>(key: string): Promise<T | string>;Also applies to: 26-26

45-45: Improvement needed for deprecation commentThe comment "this method need to be remove as soon as possible" has grammatical issues and lacks context. The file already uses proper
@deprecatedJSDoc tags, so it would be better to:
- Add more context about why it needs to be removed
- Indicate what should be used instead
- Fix the grammar
- // this method need to be remove as soon as possible + // TODO: This method needs to be removed as soon as possible. + // Replacement: Use the new storageAPI methods instead.

Function signature update requires documentation and interface update
The function signature has been changed from returning Promise<T | void> to Promise<T | string>. This is a breaking change that would require updates to any code that depends on this function. The JSDoc comment in line 33 still shows the old return type and should be updated to match.
🏁 Script executed:
#!/bin/bash
# Find usages of lscStorage in the codebase that might need updates
rg -g "*.{ts,tsx,js,jsx}" -A 5 "lscStorage\(" --no-headingLength of output: 1141
Action Required: Update JSDoc Documentation and Clean Up Deprecated Signatures
- The updated function signature now returns
Promise<T | string>instead of the previously documentedPromise<T | void>(orPromise<T | null>in some variants). - The JSDoc block at line 33 still reflects the old return type—this could mislead any consumers of the function.
- Additionally, there are multiple deprecated or commented-out variants of
lscStoragein the file. Consider removing these to avoid confusion.
Please update the JSDoc comment in src/storage.ts (starting at line 33) to correctly document the new return type, and clean up any outdated or unused function signatures accordingly.
