Develop a fully functional website designed to provide a suite of tools for YouTube content creators and viewers. The site should be built using the latest version of Bootstrap for a responsive and mobile-first design. Implement the Inter font globally for a clean and modern aesthetic, ensuring consistent typography across all pages. Integrate the YouTube Data API v3 to power the core functionality of the tools. The website should include at least the following features: a channel statistics tool that retrieves and displays detailed information such as subscriber count, view count, video count, and channel creation date; a video details tool that allows users to input a YouTube video URL and retrieve information like title, description, tags, view count, like count, comment count, and publish date; a keyword research tool that leverages the API to suggest related keywords and analyze keyword performance based on YouTube data; and a playlist analyzer that can extract and display all videos from a given playlist, along with summary statistics. Ensure proper error handling for API requests and provide clear feedback to the user. Design the user interface to be intuitive and user-friendly, with a clean layout and consistent styling. Utilize Bootstrap components effectively for forms, tables, and modals. Implement client-side JavaScript for dynamic data fetching and display, and ensure the website is optimized for performance and accessibility. Provide clear instructions and documentation for each tool, and consider incorporating a 'Help' or 'About' section for user guidance. Prioritize security when handling API keys and user inputs. The site should be responsive, working well across various screen sizes and devices. Ensure all pages are properly structured with semantic HTML5 elements and adhere to web accessibility guidelines. The website must be well documented and easy to maintain and expand upon in the future. Ensure all buttons and interactive elements are styled to provide clear visual feedback upon interaction. Use a modern build process, such as using npm and a bundler like Webpack or Parcel, to manage dependencies and optimize assets.
