Generating TypeScript PATCH Controllers

TypeScript
export const updateUserController = async (
  id: User['id'],
  params: UpdateUserParams,
): Promise<AxiosResponse<User, any>> => {
  const url = `/api/users/${id}/`;
  const instance = genRequestInstance();

  try {
    const response = await instance.patch(url, params);
    return response;
  } catch (error) {
    return Promise.reject(error);
  }
};

Progress:

• Analyze existing patterns and identify parameters
• Define function signature with proper typing
• Construct URL path with parameters
• Implement request with error handling
• Validate types match API expectations

Steps:

1. Extract URL parameters - Identify all dynamic segments in the endpoint
2. Define function name - Follow update{Entity}Controller pattern
3. Type parameters - Use namespace-qualified types for IDs and update params
4. Build URL - Interpolate parameters into API path
5. Execute request - Use patch method with genRequestInstance()
6. Handle errors - Let axios handle HTTP errors, reject on catch

Example 1: Input: "Create update controller for user profile with user ID" Output:

TypeScript
export const updateUserProfileController = async (
  id: User['id'],
  params: UpdateUserProfileParams,
): Promise<AxiosResponse<UserProfile, any>> => {
  const url = `/api/users/${id}/profile/`;
  const instance = genRequestInstance();

  try {
    const response = await instance.patch(url, params);
    return response;
  } catch (error) {
    return Promise.reject(error);
  }
};

Example 2: Input: "Create update controller for project task with project ID and task ID" Output:

TypeScript
export const updateProjectTaskController = async (
  projectId: Project['id'],
  taskId: Task['id'],
  params: UpdateProjectTaskParams,
): Promise<AxiosResponse<ProjectTask, any>> => {
  const url = `/api/projects/${projectId}/tasks/${taskId}/`;
  const instance = genRequestInstance();

  try {
    const response = await instance.patch(url, params);
    return response;
  } catch (error) {
    return Promise.reject(error);
  }
};
