`75-77`: **Consider adding JSDoc comments for the PluginStorage interface**

Since this is a key interface that represents the structure of plugin data in storage, adding JSDoc comments would help other developers understand its purpose and usage better.


```diff
+/**
+ * Interface representing plugin storage configuration.
+ * Each key represents a plugin name with its associated settings.
+ */
 interface PluginStorage {
   [key: string]: PluginStorageItem
 }
```

`197-202`: **Consider adding a return type to the closeSetting function**

While most functions have return type annotations, the closeSetting function is missing one. Consider adding the void return type for consistency.


```diff
-const closeSetting = (forceClose?: boolean) => {
+const closeSetting = (forceClose?: boolean): void => {
   const { settings } = layoutState
   if (!settings.fixedPanels.includes(settings.render) || forceClose) {
     settings.render = null
   }
 }
```

`205-215`: **Add a return type annotation to the activePlugin function**

The activePlugin function is missing a return type annotation. Since it returns a Promise, you should add the appropriate return type.


```diff
-const activePlugin = (name: string, noActiveRender: boolean) => {
+const activePlugin = (name: string, noActiveRender: boolean): Promise<any> => {
   const { plugins } = layoutState

   if (!noActiveRender) {

 }

`227-240`: **Add type annotation to getPluginWidth function's return value**

---

`20-415`: <details>
<summary>❓ Verification inconclusive</summary>

**Verify type consistency across the codebase**

The types added to this file are robust and appropriate. However, ensure that consuming code that calls these functions is updated to align with the new type requirements, especially for functions that now have more specific parameter types like `changeMenuShown` which requires 'left' | 'right'.

---

🏁 Script executed:

```shell
#!/bin/bash
# Search for calls to changeMenuShown with arguments that might not match the new type requirements
rg "changeMenuShown\(.*[^'\"](left|right)[^'\"].*\)" --type ts
```

Length of output: 68

---



</details>

**Ensure all invocations of `changeMenuShown` strictly pass `'left'` or `'right'` as arguments.**  
Our automated search in the codebase for calls to `changeMenuShown` that might violate its parameter type did not reveal any instances of misuse. However, because the script output was inconclusive, please manually verify that all consuming code correctly uses the literal `'left'` or `'right'` values in accordance with the updated type requirements.  
- Verify that everywhere `changeMenuShown` is called, the argument is explicitly a `'left'` or `'right'` literal.  
- Confirm that any variables passed to it are properly typed to only allow these two values.

<summary>packages/layout/src/composable/useLayout.ts (4)</summary><blockquote>

`21-23`: **The PluginNameType definition is a good start but could be more specific.**

Using `typeof PLUGIN_NAME` correctly captures the type of the PLUGIN_NAME constant. However, consider using a more specific type if the structure of PLUGIN_NAME is known in advance, as this would provide better autocompletion support.

---

`24-27`: **IMetaApi interface is too generic.**

The IMetaApi interface is defined with an index signature that allows any property with any type. This provides very little type safety. Consider defining a more specific structure if the shape of the API is known.


```diff
interface IMetaApi {
-  [key: string]: any
+  // Add specific properties that are known to exist
+  // For example:
+  // getPlugin?: (name: string) => IPlugin
+  // Or at least constrain the value type if possible
+  [key: string]: Function | object | string | number | boolean
}
```

---

`76-76`: **Use specific type instead of 'any' for pageStatus.**

Using `any` for `pageStatus` reduces type safety. Consider using a more specific type, such as a string union type based on the available page statuses in constants.


```diff
-  pageStatus: any
+  pageStatus: typeof PAGE_STATUS[keyof typeof PAGE_STATUS] | string
```

---

`97-97`: **Avoid using index signature with 'any' type in IPlugin.**

The index signature `[key: string]: any` in the IPlugin interface reduces type safety. Consider either removing it if all properties are known, or constraining the value type.


```diff
interface IPlugin {
  id: string
  componentName?: string
  name?: string
  label?: string
-  [key: string]: any
+  // Add more specific properties or constrain the value type
+  [key: string]: string | number | boolean | undefined | object
}

`20-23`: **IMetaApi interface is overly permissive**

This interface uses `[key: string]: any` which provides minimal type safety. Consider defining more specific properties if known, or adding documentation explaining why this generic structure is necessary.

```diff
// MetaApi 类型定义
interface IMetaApi {
  [key: string]: any
+  // TODO: Add specific known properties to improve type safety
}
```

---

`34-36`: **Consider using more specific union type for pluginEvent**

Using `'all' | string` is functionally equivalent to just `string` since it allows any string value. If there are specific valid values for pluginEvent, consider listing them explicitly in the union.

```diff
interface IPluginState {
-  pluginEvent: 'all' | string
+  pluginEvent: 'all' | 'specific1' | 'specific2' | string
}
```

---

`70-77`: **Remove redundant `undefined` in optional properties**

The `?` operator already indicates that a property can be undefined, so adding `| undefined` is redundant.

  align?: string
  index: number
  isShow?: boolean
  widthResizable?: boolean

`175-175`: **Inconsistent return type annotation style**

The getScale function uses arrow function shorthand for return type, while other functions use explicit type annotations. For consistency, consider using the same style as other functions.

<summary>❌ Incorrect review comment</summary>

**Need explicit return type for object properties**

The return object contains many methods and properties without type declarations. Consider adding type annotations to each method in the return object for maximum type safety.

---

🌐 Web query:

```web
Is it necessary to declare types for properties in a return object in TypeScript, or will TypeScript infer these types correctly?
```

💡 Result:

In TypeScript, explicit type annotations for return object properties are generally **not necessary** because the compiler can accurately infer their types from the returned values. However, there are scenarios where explicit typing becomes beneficial or necessary.

### Key Inference Capabilities
1. **Automatic type inference**  
   TypeScript infers object property types based on initial values:
   ```typescript
   function getUser() {
     return {
       id: 1,          // inferred as number
       name: "Alice"   // inferred as string
     };                // Return type: { id: number; name: string }
   }
   ```

2. **Const assertions**  
   For literal values, use `as const` to preserve exact types:
   ```typescript
   function getStatus() {
     return { code: 200, message: "OK" } as const;
   }
   // Inferred return type: { readonly code: 200; readonly message: "OK" }
   ```

### When Explicit Typing Helps
| Scenario | Example | Benefit |
|----------|---------|---------|
| Multiple return branches | `function parse(input: string): { success: boolean; data?: string } { ... }` | Ensures consistent type across code paths [3][11] |
| Library development | `export function createConfig(): Readonly<Config> { ... }` | Improves declaration file generation [3] |
| Complex transformations | `type Transformed<T> = { [K in keyof T]: T[K] extends string ? Date : T[K] }` | Maintains intentional type relationships [4][13] |
| Documentation clarity | `interface User { id: number; name: string }`<br>`function getUser(): User { ... }` | Acts as built-in documentation [9][12] |

### Inference Limitations
- **Mutable variables** may widen types unintentionally:
  ```typescript
  function getCounter() {
    const count = 0;  // inferred as number
    return { count, increment: () => count++ };
  }
  // count remains number, but explicit annotation could enforce stricter numeric subtypes
  ```

- **Empty objects** require explicit typing:
  ```typescript
  function createWidget(): Widget {
    return {};  // Error without Widget interface definition
  }
  ```

For most application code, **relying on type inference** is preferred to reduce boilerplate while maintaining type safety. Explicit return type annotations become valuable in libraries, complex functions, or when enforcing specific contracts across teams[3][6].

**Explicit Return Types Are Optional Here**

Based on TypeScript’s strong type inference, the code in `packages/layout/src/composable/useLayout.ts` (lines 384–422) correctly infers all object property types from their implementations. Explicit return type annotations aren’t necessary unless you need a clear contract for external consumers or additional documentation. If this module is internal or its API is clear through inference, the current approach is acceptable.

return new Promise<IMetaApi>((resolve) => {
-  nextTick(() => resolve(getMetaApi(name)))
+  nextTick(() => {
+    try {
+      resolve(getMetaApi(name))
+    } catch (error) {
+      console.error(`Failed to get meta API for plugin ${name}:`, error)
+      resolve({} as IMetaApi)
+    }
+  })
})
```

---

`248-252`: **Improved error handling but could be more specific**

The error handling has been improved with proper type checking, but the error message for non-Error instances is generic.


```diff
if (error instanceof Error) {
  throw new Error(error.message)
} else {
-  throw new Error('Failed to parse plugin storage')
+  throw new Error(`Failed to parse plugin storage: ${String(error)}`)
}
```

---

`239-423`: **Consider adding JSDoc comments to exported function**

The main exported function and its returned methods lack JSDoc comments explaining their purpose, parameters, and return values.


Adding JSDoc comments would improve the developer experience and documentation:

```diff
+/**
+ * Provides utilities for managing the layout of plugins and settings in the application.
+ * @returns An object containing methods and properties for layout management.
+ */
export default () => {
  // ...
}
```

```web
Are explicit return type interfaces recommended in Vue 3 composition API functions or is type inference sufficient?
```

💡 Result:

In Vue 3's Composition API, Type Inference is generally sufficient for most use cases due to its robust integration with TypeScript, but explicit return type interfaces are recommended in specific scenarios for enhanced type safety and clarity.

### Type Inference Strengths
1. **Automatic type detection**:  
   Composition API's reactivity primitives (`ref`, `reactive`, `computed`) infer types automatically[1][6][13]. For example:
   ```typescript
   const count = ref(0)  // Inferred as Ref<number>
                         // No explicit type needed
   ```

2. **Template ref auto-unwrapping**:  
   Ref values in templates are automatically unwrapped with correct type inference[16].

3. **Composable arguments**:  
   Function parameters in composables get inferred types when using TypeScript[15].

### When to Use Explicit Return Types
| Scenario | Example | Benefit |
|----------|---------|---------|
| Complex return objects | `interface AuthState { user: Ref<User>, token: Ref<string> }`<br>`function useAuth(): AuthState { ... }` | Prevents fragmented type declarations[11][15] |
| Union/intersection types | `function useToggle(): [Ref<boolean>, () => void]` | Avoids array-to-tuple conversion issues[4][15] |
| Public composables | `export function usePagination<T>(): PaginationResult<T>` | Ensures contract stability for consumers[15] |
| Conditional returns | `function useFetch<T>() => { data: Ref<T \| null>, error: Ref<Error> }` | Clarifies branching logic outcomes[4] |

### Performance & Best Practices
- **Runtime vs Type-based declarations**:  
  Type-based props via generics (`defineProps<{...}>()`) have better inference than runtime declarations using `PropType`[1][5][11].

- **Computed properties**:  
  Explicit generics prevent inference errors:
  ```typescript
  const double = computed<number>(() => ...)  // Enforce numeric return
  ```

- **IDE benefits**:  
  Explicit types improve autocomplete and type checking in IDEs like VSCode[15].

While Vue 3's Composition API reduces boilerplate through effective type inference[2][6][13], explicit return types become valuable in complex scenarios and public APIs. The official Vue documentation recommends leveraging TypeScript's inference where possible, while using explicit typing for shared libraries and critical business logic[1][3][5].

**Explicit Return Type for UseLayout Composable**

Although Vue 3’s Composition API offers robust type inference, explicit return type annotations are recommended for public composables—especially when returning complex objects—to ensure clarity and maintainability. In this case, defining an explicit interface for the return value of `useLayout` enhances the API contract and aligns with best practices.

- **Define an interface** (e.g., `IUseLayoutReturn`) specifying all properties and methods being returned.
- **Annotate the exported function** with this interface to signal its public API clearly.

Revised diff snippet:

```diff
-export default () => {
+export interface IUseLayoutReturn {
+  isPanelWidthResizable: (name: string) => boolean;
+  getFixedPanelsStatus: () => { leftPanelFixed: boolean; rightPanelFixed: boolean };
+  initPluginStorageReactive: (pluginList: IPluginStorage) => void;
+  PLUGIN_NAME: any;
+  PLUGIN_POSITION: IPluginPosition;
+  activeSetting: (name: string) => void;
+  closeSetting: (forceClose?: boolean) => void;
+  activePlugin: (name: string, noActiveRender: boolean) => Promise<IMetaApi>;
+  closePlugin: (forceClose?: boolean) => void;
+  layoutState: ILayoutState;
+  getScale: () => number;
+  setDimension: (data: Partial<IDimension>) => void;
+  getDimension: () => IDimension;
+  getPluginById: (pluginList: IPlugin[], pluginId: string) => IPlugin | undefined;
+  pluginState: IPluginState;
+  getPluginState: () => IPlugins;
+  getSettingState: () => ISettings;
+  isEmptyPage: () => boolean;
+  // Add any additional return properties as needed...
+}
+
+export default (): IUseLayoutReturn => {
```

This explicit typing not only clarifies the module's interface for consumers but also aids in effective IDE support and type checking.

`20-92`: **Good addition of type interfaces.**

The introduction of clear TypeScript interfaces for the layout system components provides better type safety and code documentation. These interfaces will help catch errors at compile time rather than runtime.

---

`69-69`: **Replace `any` type with a more specific interface.**

Using `any` loses type safety. Since `pageStatus` is accessed with a `.state` property elsewhere, consider creating a more specific interface.



```diff
-  pageStatus: any
+  pageStatus: {
+    state: string
+    [key: string]: unknown
+  }
```

---

`102-102`: **Good use of generic type parameter with reactive.**

The addition of the generic type parameter `<IPluginState>` to the reactive call ensures proper type checking of the reactive object properties.

---

`146-148`: **Excellent use of generic types with useStorage.**

Adding generic type parameters to useStorage calls provides better type safety for stored values.

---

`226-226`: **Good Promise typing.**

Adding the return type `Promise<IMetaApi>` to the promise ensures that consumers of this function know what type to expect when the promise resolves.

---

`241-242`: **Missing return type definition for useLayout function.**

The main exported function lacks a return type annotation, which would complete the type safety of this module.

**Export Additional Interfaces for External Use – Resolved**

The file now exports several interfaces beyond those in the initially shown snippet. In addition to `IPluginStorageItem`, `IPluginStorage`, and `IPlugin`, the file also exports interfaces such as `IMetaApi`, `IPluginPosition`, `IPluginState`, `IDimension`, `IPluginBase`, `IPlugins`, `ISettings`, and `ILayoutState`. These additional exports address the concerns raised by gene9831 regarding type errors in other modules.

No further changes are needed in this regard.

`244-244`: **Consider adding return type annotation to the main exported function.**

For better type safety and documentation, consider adding a return type annotation to the main exported function.


You can either:
1. Let TypeScript infer the return type (current approach)
2. Create a specific return type interface

According to past comments, gene9831 suggested letting TypeScript infer the type, which is a valid approach.

---

`168-178`: **Consider refactoring similar functions to reduce duplication.**

The `changeLeftFixedPanels` and `changeRightFixedPanels` functions have nearly identical implementations and could be refactored into a single helper function.


```diff
+const toggleFixedPanel = (storage: Ref<string[]>, pluginName: string): void => {
+  storage.value = storage.value?.includes(pluginName)
+    ? storage.value?.filter((item) => item !== pluginName)
+    : [...storage.value, pluginName]
+}
+
 const changeLeftFixedPanels = (pluginName: string): void => {
-  leftFixedPanelsStorage.value = leftFixedPanelsStorage.value?.includes(pluginName)
-    ? leftFixedPanelsStorage.value?.filter((item) => item !== pluginName)
-    : [...leftFixedPanelsStorage.value, pluginName]
+  toggleFixedPanel(leftFixedPanelsStorage, pluginName)
 }

 const changeRightFixedPanels = (pluginName: string): void => {
-  rightFixedPanelsStorage.value = rightFixedPanelsStorage.value?.includes(pluginName)
-    ? rightFixedPanelsStorage.value?.filter((item) => item !== pluginName)
-    : [...rightFixedPanelsStorage.value, pluginName]
+  toggleFixedPanel(rightFixedPanelsStorage, pluginName)
 }
```

Note: You'll need to import `Ref` from 'vue' for this change.

</details>

**Verified: Interface Exports Are Correct**

The interface definitions in `packages/layout/src/composable/useLayout.ts` are well-structured and properly exported. The grep search confirms that interfaces like `IPluginStorageItem`, `IPluginStorage`, and `IPlugin` are referenced in other parts of the codebase (e.g., in `packages/vue-generator/src/index.d.ts`), which indicates that the VS Code errors related to type exports have been resolved.

LGTM!

body: _⚠️ Potential issue_

**Potential issue with object assignment.**

The current implementation assigns an object with only a `width` property when the plugin name is not found in the storage. This may lead to inconsistent data structure as other functions expect additional properties like `align`, `index`, etc.


```diff
} else {
-  Object.assign(pluginStorageReactive.value, { width })
+  pluginStorageReactive.value[name] = { 
+    width, 
+    index: 0, 
+    isShow: true 
+  }
}
```

**Avoid using `any` type for pageStatus**

Using `any` loses type safety. Since pageStatus is accessed with a `.state` property on line 237, consider creating a more specific interface for this property.

```diff
-  pageStatus: any
+  pageStatus: {
+    state: string

**Missing return type definition for useLayout function**

The main exported function useLayout lacks a return type annotation, which would complete the type safety of this module.

**Consider exporting IPluginStorageItem interface**

The `IPluginStorageItem` interface is not exported, but it might be needed in other files that import `IPluginStorage`. Consider exporting this interface to avoid type errors in other files.

```diff
-interface IPluginStorageItem {
+export interface IPluginStorageItem {
```

---

🏁 Script executed:

```shell
#!/bin/bash
# Check if IPluginStorageItem is used in other files
rg "IPluginStorageItem" --type ts
```

Length of output: 188

---



</details>

**Action: Export IPluginStorageItem for External Usage**

After verification, we confirmed that the only occurrences of `IPluginStorageItem` are within `packages/layout/src/composable/useLayout.ts` (including its use in an index signature). Although it's currently used only internally, the design implies that it may be required by other files that import `IPluginStorage`. To avoid potential type errors when used externally, please export the interface.

```diff
-interface IPluginStorageItem {
+export interface IPluginStorageItem {
```

body: 这里返回的是一个数组，从类型的逻辑上看，数组元素不应该为 `undefined`，因为存在 `undefined`，可能导致其他地方的代码遍历此数组返回值时，导致一些运行时错误。你可以使用 `filter` 把 `undefined` 过滤掉，但是由于 `filter` 在当前ts版本似乎不会主动过滤类型。你需要加一个类型断言`: plugin is IPlugin`
```ts
return getPluginsByLayout(position).map((pluginId) => getPluginById(pluginList, pluginId)).fitler((plugin): plugin is IPlugin => Boolean(plugin))

## Walkthrough
The changes introduce a significant expansion of TypeScript interfaces and type annotations within the `useLayout.ts` file. New interfaces define various entities related to the plugin layout system, while existing variables and functions have been updated to include explicit type definitions. Additionally, storage usage has been refined with the inclusion of generic types in `useStorage` calls. Error handling has been improved with explicit error messages. These modifications enhance type safety and clarity across the codebase without altering core logic or control flow.

## Changes
| File                                                        | Change Summary |
|-------------------------------------------------------------|----------------|
| `packages/layout/src/composable/useLayout.ts` (Interfaces)  | Added interfaces: `IMetaApi`, `IPluginPosition`, `IPluginState`, `IDimension`, `IPluginBase`, `IPlugins`, `ISettings`, `ILayoutState`, `IPluginStorageItem`, `IPluginStorage`, `IPlugin`. |
| `packages/layout/src/composable/useLayout.ts` (Function Signatures) | Updated function signatures with parameter and return type annotations for functions including `getMoveDragBarState`, `changeMoveDragBarState`, `changeMenuShown`, `changeLeftFixedPanels`, `changeRightFixedPanels`, `getScale`, `getPluginState`, `getSettingState`, `getDimension`, `setDimension`, `activeSetting`, `closeSetting`, `activePlugin`, `closePlugin`, `getPluginWidth`, `changePluginWidth`, `getPluginByLayout`, `getPluginsByLayout`, `getPluginById`, `getPluginsByPosition`, `changePluginLayout`, `dragPluginLayout`, `isSameSide`, `getPluginShown`, `changePluginShown`, `isPanelWidthResizable`, `initPluginStorageReactive`. |
| `packages/layout/src/composable/useLayout.ts` (Variables)   | Added explicit type annotations to constants `PLUGIN_POSITION`, `pluginState`, and `layoutState`. |
| `packages/layout/src/composable/useLayout.ts` (Storage Calls) | Specified generic types in `useStorage` calls for stored values (e.g., `useStorage<boolean>`, `useStorage<string[]>`). |
| `packages/layout/src/composable/useLayout.ts` (Error Handling) | Refined localStorage parsing logic to throw errors with explicit messages. |

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=opentiny/tiny-engine&utm_content=1269):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
