# Task ID: 1
# Title: Setup Chat SDK Module & Define Core Types
# Status: done
# Dependencies: None
# Priority: high
# Description: Initialize the new chat module within the SDK. Define/generate all required TypeScript types (e.g., Chat, WAMessage, options objects) from the WAHA Swagger/OpenAPI specification. Ensure type safety foundation for all chat operations.
# Details:
Establish the foundational structure for the Chats SDK. Generate or manually define TypeScript interfaces and types for all request parameters and response payloads as specified in the WAHA Swagger (e.g., GetChatsOptions, Chat, ChatOverview, ChatPictureResponse, ReadChatMessagesResponse, GetMessagesOptions, WAMessage). Ensure these types are integrated and accessible within the SDK. This aligns with NFR for Type Safety.

# Test Strategy:
Review generated types against Swagger specification. Verify module structure and type accessibility within the SDK.

# Subtasks:
## 1. Initialize Chat SDK Module Structure and Build Configuration [done]
### Dependencies: None
### Description: Create the basic directory structure for the new Chat SDK module, set up initial build configurations (e.g., tsconfig.json, package.json scripts), and define the main export points (e.g., index.ts).
### Details:
This involves creating folders for source code (e.g., `src`), types (e.g., `src/types`), and potentially utilities. Configure the TypeScript compiler options for the module and add necessary scripts to `package.json` for building and linting. Establish the primary `index.ts` file that will serve as the module's entry point for exports.
<info added on 2025-06-08T21:40:59.198Z>
File and Directory Creation Plan:
New file src/chats.ts for main chat functions.
New directory src/types/.
New file src/types/chat.types.ts for chat-related TypeScript types.
Existing src/index.ts will be updated in a later subtask (1.3) for exports.
Configuration Review Plan:
Review tsconfig.json for compilation paths.
Review package.json for script impacts.
Execution Steps:
Log this plan (this step).
Set status to in-progress.
Create src/chats.ts.
Create src/types/chat.types.ts (and src/types/ directory).
Read tsconfig.json and package.json.
Log outcome.
Set status to done.

<info added on 2025-06-08T21:41:39.910Z>
Outcome of execution:
- Successfully created `src/chats.ts`.
- Successfully created `src/types/chat.types.ts` (and `src/types/` directory).
- Reviewed `tsconfig.json`: No changes needed as `"rootDir": "src"` and `"include": ["src/**/*.ts"]` cover the new files.
- Reviewed `package.json`: No changes needed as `projen` manages scripts, which should automatically pick up new files in `src/`.

## 2. Define Core TypeScript Types from WAHA OpenAPI Specification [done]
### Dependencies: 1.1
### Description: Generate or manually define all core TypeScript types and interfaces (e.g., Chat, WAMessage, GetChatsOptions, ChatOverview, ChatPictureResponse, ReadChatMessagesResponse, GetMessagesOptions) derived from the provided WAHA Swagger/OpenAPI specification.
### Details:
Carefully review the WAHA Swagger/OpenAPI specification to identify all necessary data structures. Create corresponding TypeScript interfaces or types, ensuring accuracy in property names, data types, and optionality. Consider using an OpenAPI-to-TypeScript generation tool for initial scaffolding, followed by manual review and refinement. Store these type definitions in a dedicated location within the module structure created in Subtask 1.
<info added on 2025-06-08T21:43:08.495Z>
1. Tool Selection: Use `openapi-typescript` to generate types from WAHA Swagger (`https://waha.devlike.pro/swagger/openapi.json`).
2. Execution Steps:
    a. Set status to `in-progress`.
    b. Attempt `npx openapi-typescript`. If not found, install with `yarn add --dev openapi-typescript`.
    c. Generate all types into temporary file: `npx openapi-typescript https://waha.devlike.pro/swagger/openapi.json --output src/types/waha.generated.ts`.
    d. Review PRD and `waha.generated.ts` to identify and extract types for the 6 chat endpoints (e.g., `GetChatsOptions`, `Chat`, `ChatOverview`, `ChatPictureResponse`, `ReadChatMessagesResponse`, `GetMessagesOptions`, `WAMessage`, and related nested types).
    e. Copy selected types into `src/types/chat.types.ts`, ensuring they are exported.
    f. Add a header comment to `src/types/chat.types.ts` about the source and tool.
    g. Delete `src/types/waha.generated.ts`.
    h. Log actions and key types added to subtask details.
    i. Set status to `done`.

openapi-typescript tool failed due to an issue in the WAHA Swagger spec: `Error: Expected SchemaObject, received string at #/components/schemas/WAHAWebhookSessionStatus/event`.

Revised Plan for Subtask 1.2 (Manual Type Definition):
1. Strategy: Manually define TypeScript types in `src/types/chat.types.ts` based on `prd.txt` and direct inspection of `https://waha.devlike.pro/swagger/openapi.json`.
2. Types to Define (from PRD):
    - `GetChatsOptions`
    - `Chat`
    - `GetChatsOverviewOptions`
    - `ChatOverview`
    - `GetChatPictureOptions` (from PRD: `options?: { refresh?: boolean }`)
    - `ChatPictureResponse`
    - `ReadMessagesOptions` (from PRD: `options?: { messages?: number, days?: number }`)
    - `ReadChatMessagesResponse`
    - `GetMessagesOptions`
    - `WAMessage`
    - `GetMessageByIdOptions` (from PRD: `options?: { downloadMedia?: boolean }`)
3. Execution Steps:
    a. Fetch and inspect `https://waha.devlike.pro/swagger/openapi.json` to understand the structure of the above types and any nested/common types they use.
    b. Create/update `src/types/chat.types.ts` with manual definitions for these types, ensuring they are exported.
    c. Add a header comment in `src/types/chat.types.ts` noting the manual definition and the original generator issue.
    d. Log actions and key types defined to subtask details.
    e. Set status to `done`.

## 3. Integrate and Export Core Types within Chat SDK Module [done]
### Dependencies: 1.1, 1.2
### Description: Organize the defined TypeScript types within the Chat SDK module's structure and ensure they are properly exported from the module's main entry point, making them accessible for use in subsequent chat operations and by consumers of the SDK.
### Details:
Place the type definition files (from Subtask 2) into the designated 'types' directory (or similar, established in Subtask 1). Update the module's main export file (e.g., `src/index.ts`) to re-export all core types. Ensure a clean and logical organization of type files if multiple files are used (e.g., `chat.types.ts`, `message.types.ts`).
<info added on 2025-06-08T21:47:25.413Z>
Refined plan for Subtask 1.3:
1. File Organization Review:
    - Types are correctly located in `src/types/chat.types.ts`.
    - All interfaces in `chat.types.ts` are already exported.
2. Update Main Export File (`src/index.ts`):
    - Read `src/index.ts`.
    - Add `export * from './types/chat.types';` to `src/index.ts` to re-export chat types.
3. Execution Steps:
    a. Log this plan (current step).
    b. Set status to `in-progress`.
    c. Read `src/index.ts`.
    d. Edit `src/index.ts` to add the type exports.
    e. Log successful update to subtask details.
    f. Set status to `done`.

## 4. Verify Type Definitions and Basic Module Import/Export [done]
### Dependencies: 1.3
### Description: Perform an initial verification of the generated/defined types against the Swagger specification for accuracy, completeness, and adherence to naming conventions. Confirm basic module import/export functionality by attempting to import the module and its types in a test environment.
### Details:
Cross-reference the implemented TypeScript types (from Subtask 2 & 3) with the WAHA Swagger/OpenAPI specification to check for discrepancies. Validate naming conventions (e.g., PascalCase for interfaces/types). Create a simple test file or use a temporary project setup to `import` the Chat SDK module and specific types to ensure they are correctly exported and accessible without build or runtime errors.
<info added on 2025-06-08T21:55:53.763Z>
Plan for Subtask 1.4:
1. Type Definition Review (Mental Check):
    - Confirm PRD-based types are in src/types/chat.types.ts.
    - Confirm PascalCase naming and export * in src/index.ts.
2. Basic Import/Export Test:
    - Create temporary test/chat-types-import.test.ts.
    - Import types like Chat, WAMessage, GetChatsOptions from ../src.
    - Declare dummy variables using these types.
    - Run npx projen compile to check for errors.
3. Execution Steps:
    a. Log this plan (current step).
    b. Set status to in-progress.
    c. Create temporary test file with imports.
    d. Run compile script.
    e. Delete temporary test file.
    f. Log outcome to subtask details.
    g. Set status to done.

<info added on 2025-06-08T21:56:41.446Z>
Compilation failed. Errors:
1. Name Collision (TS2308): `WAMessage` exported by both `./messages` and `./types/chat.types.ts`.
2. JSII Readonly Properties (JSII3008): Properties in types from `chat.types.ts` are missing `readonly`.

Revised Plan for Subtask 1.4:
1. Fix `WAMessage` Conflict:
   - Rename `WAMessage` in `src/types/chat.types.ts` to `ChatWAMessage`.
   - Update references within `chat.types.ts` to use `ChatWAMessage`.
2. Add `readonly` Modifiers:
   - Add `readonly` to all properties of all interfaces in `src/types/chat.types.ts`.
3. Update Test File:
   - Modify `test/chat-types-import.test.ts` to import and use `ChatWAMessage`.
4. Re-compile:
   - Run `npx projen compile`.
5. Final Steps (if compile successful):
   - Delete `test/chat-types-import.test.ts`.
   - Log success.
   - Set status to `done`.
</info added on 2025-06-08T21:56:41.446Z>
<info added on 2025-06-08T21:57:23.914Z>
Compilation failed again. New errors (JSII8002):
1. Property 'timestamp.lte' in GetMessagesFilterOptions must be camelCase (e.g., timestampLte).
2. Property 'timestamp.gte' in GetMessagesFilterOptions must be camelCase (e.g., timestampGte).

Further Revised Plan for Subtask 1.4:
1. Fix camelCase Property Names:
   - In src/types/chat.types.ts, within GetMessagesFilterOptions:
     - Change 'timestamp.lte'?: number; to readonly timestampLte?: number;
     - Change 'timestamp.gte'?: number; to readonly timestampGte?: number;
2. Re-compile:
   - Run npx projen compile.
3. Final Steps (if compile successful):
   - Delete test/chat-types-import.test.ts.
   - Log success.
   - Set status to done.

<info added on 2025-06-08T21:57:52.776Z>
Successfully verified type definitions and basic module import/export. Compilation (`npx projen compile`) passed after resolving JSII errors related to name collision for `WAMessage`, missing `readonly` modifiers, and non-camelCase property names (e.g., `timestamp.lte` to `timestampLte`). The temporary test file `test/chat-types-import.test.ts` was created for verification and subsequently deleted. All planned fixes were implemented.
