What Is Base URL Extractor?

A Base URL Extractor is a tool designed to extract the base url from a given link, which is essential in network operations. It is primarily used by developers and network engineers who need to get the root url from a full url. One specific problem it solves is handling invalid urls, as it catches errors and provides an error message when the input url does not include a protocol.

The tool's ability to run entirely in the browser with no data sent to any server ensures instant results and makes it suitable for users who require a mobile-friendly interface. It utilizes modern browser APIs and pure JavaScript to achieve this functionality. What sets it apart is its batch mode feature, which allows users to extract base urls from multiple links at once by entering one url per line in a textarea.

It also provides an option to copy the extracted base url or individual components such as scheme, hostname, and port. This online base url parser supports both http and https protocols and can even determine the default port number if not specified in the url. For instance, it can extract base url from link https://example.com:8080/path/to/page and break down its components into origin, scheme, hostname, and port. The tool's features make it a useful base url finder tool for network operations.

Technical Guide

The tool works under the hood by utilizing the URL API in modern browsers to break down input URLs into their constituent parts. When a user inputs a URL, it is passed through the `URL` constructor, which parses the string and returns a `URL` object containing properties such as `origin`, `protocol`, `hostname`, and `port`. This information is then extracted and displayed to the user in a readable format. The tool also uses React hooks, specifically `useState` and `useMemo`, to manage state and optimize performance by memoizing expensive function calls. In batch mode, it splits the input string into an array of URLs using the newline character as a delimiter, and then maps over this array to extract the base URL from each individual URL.

The tool's input validation is handled by a try-catch block that catches any errors thrown by the `URL` constructor when attempting to parse an invalid URL. If an error occurs, it sets the error state to a message indicating that the input URL is invalid and does not include a protocol. The use of ES6+ features such as destructuring and arrow functions helps keep the code concise and readable. Additionally, the tool uses the `copyToClipboard` function from the `@/lib/utils` module to handle copying extracted base URLs or individual components to the user's clipboard. Overall, the combination of modern browser APIs, React hooks, and careful input validation makes it a reliable and efficient base URL extractor.

In terms of data structures, the tool uses JavaScript objects to store extracted URL information, with properties such as `origin`, `scheme`, `hostname`, and `port`. It also uses arrays to store batch mode results, where each element in the array represents an individual URL extraction result. The use of React's `useCallback` hook helps optimize performance by memoizing expensive function calls, such as the `handleCopy` function, which is used to copy extracted base URLs or individual components to the user's clipboard. By leveraging these technologies and data structures, the tool provides a fast and accurate way to extract base URLs from input strings.
