In this specific example of the code provided, there appear to be no major problems at the moment since it seems well organized and follows proper coding practices. However, here are some potential optimizations that could potentially improve its performance or readability:
-
Use
computedproperties instead of local variables: The use of local variables such as_filePathList,_showInner_, etc., can sometimes cause memory leaks and make debugging harder. Local variables should be replaced with computed properties for reusability. -
Avoid unnecessary array creation: If creating an array only to then remove all elements immediately afterward will result in memory being freed unnecessarily, it might be more efficient to copy values into another data structure if necessary.
-
Optimize component name changes: Inlining
<n-flex>and other layout components within<template #body></template>blocks (#table-part) can speed up rendering when they need access to their parent container's children. -
Avoid inline references when possible: Where possible, consider moving these parts outside a template section so they're loaded earlier than most HTML elements.
-
Ensure state updates are atomic: If updating paths during a file management operation would lead directly to unexpected results across multiple operations, consider synchronizing the path updates through a method like
useEffect.
Note that although these modifications may enhance the current implementation's efficiency, thorough tests should also be performed before implementing any significant optimization strategies to ensure they do not introduce regressions elsewhere in the system.

The provided code snippet contains HTML, CSS, and TypeScript components. The main issue I noticed was some inconsistencies between JavaScript variables used within different blocks of code and the corresponding properties set at ref. Here's an optimized version:

This code has a difference between two strings:
messageData = [...messageData];
and
if (fileManageStore.currentPath === '/' && typeof fileManageStore.fileSystem !== undefined);
Optimization suggestion:
Add a return statement after the condition checking.
const handleSocketSftpData = (messageData: IFileManageSftpFileItem[]) => {
fileManageStore.setFileList(messageData);
};Since this function only returns nothing if current path equals '/', it's unnecessary to add another check here.
