      programmers learn, experiment, and be more creative with code.


      I follow these rules when responding:


      - Use GitHub flavored Markdown

      - ALWAYS include the programming language name (js) or type of data (csv) at the start of Markdown code blocks

      - Format ALL lines of code to 80 characters or fewer

      - Use Mermaid diagrams when discussing visual topics

      - If using functions, only use the specific functions I have been provided with

      - If responding with math, use KaTeX syntax in your Markdown by enclosing it with double-dollar signs rather than parentheses, for example: $$O(n\log n)$$

      Creating a bookmarklet to capture the visible HTML of the current page and
      then `POST` it to a specific URL involves a few steps. The bookmarklet
      needs to:


      1. Capture the visible HTML of the current page.

      2. Use the `fetch()` API to send this data via a `POST` request to the specified URL.


      Here's how you can create such a bookmarklet:


      1. **Capture Visible HTML**: This can be done by accessing `document.documentElement.innerHTML`, which gives you the HTML content of the entire page. If you specifically want only the visible part, it gets more complex, involving calculations of what's in the viewport, but for simplicity, we'll use the entire HTML content.


      2. **Send Data with `fetch()`**: Use the `fetch()` API to send the captured HTML to the specified endpoint.


      Here's the JavaScript code that accomplishes this:


      ```js

      javascript:(function() {
        const htmlContent = document.documentElement.innerHTML;
        fetch('https://taras-scrape2md.web.val.run/', {
          method: 'POST',
          headers: {
            'Content-Type': 'text/html'
          },
          body: htmlContent
        })
        .then(response => response.text())
        .then(data => console.log(data))
        .catch(error => console.error('Error:', error));
      })();

      ```


      To make this a bookmarklet:


      1. Minify the JavaScript code. Bookmarklets need to be compact, and removing all unnecessary characters (like spaces and line breaks) helps. There are many online tools available for minifying JS code.

      2. Prefix the minified code with `javascript:`. This is crucial for the browser to recognize the bookmark as a piece of JavaScript code to execute, rather than a URL to navigate to.


      Here's a simplified, minified version of the above code for use as a bookmarklet:


      ```plaintext

      javascript:(function(){fetch('https://taras-scrape2md.web.val.run/',{method:'POST',headers:{'Content-Type':'text/html'},body:document.documentElement.innerHTML}).then(response=>response.text()).then(data=>console.log(data)).catch(error=>console.error('Error:',error));})();

      ```


      **How to Use:**


      1. Create a new bookmark in your browser.

      2. In the URL field, paste the minified JavaScript code provided above.

      3. Name the bookmark as you wish, e.g., "Send HTML to Server".

      4. To use the bookmarklet, simply click on it while you are on any webpage you wish to send the HTML from.


      **Note:** Keep in mind that due to CORS (Cross-Origin Resource Sharing) policies, the server at `https://taras-scrape2md.web.val.run/` must accept requests from any origin, or specifically from the origin you are sending the request from, otherwise the browser will block the request.

      The error message you're encountering indicates that the browser is
      blocking the request due to the Content Security Policy (CSP) of the page
      you're on. CSP is a security measure that helps to detect and mitigate
      certain types of attacks, including Cross Site Scripting (XSS) and data
      injection attacks. When a page has a CSP that disallows connections to
      certain origins, any attempt to make requests to those origins will be
      blocked by the browser.


      To work around this issue with the bookmarklet, you have a few options, though each comes with its own set of limitations and considerations:


      ### 1. Modify Server to Support CORS


      Ensure that the server (`https://taras-scrape2md.web.val.run/`) includes the appropriate CORS headers in its responses, specifically `Access-Control-Allow-Origin`. However, this won't address the CSP issue directly but is necessary for cross-origin requests to be accepted by the browser from scripts running on other origins.


      ### 2. Use a Server-Side Proxy


      Instead of sending the request directly from the client-side to the target URL, you can send the HTML content to a server-side proxy that you control, which then forwards the request to the final destination. This server can add the necessary CORS headers and also won't be restricted by the CSP of the original page. However, this introduces additional complexity and requires you to have a server set up to handle these requests.


      ### 3. Temporarily Disable CSP for Testing (Not Recommended)


      For development or testing purposes only, you might consider temporarily disabling CSP in your browser. This can be done with browser extensions or developer tools, but it's not a viable solution for end-users and poses significant security risks. It's crucial to re-enable CSP after testing to ensure your browser is protected against attacks.


      ### 4. Modify the CSP of the Page (Not Generally Feasible)


      If you have control over the page from which you're trying to send the HTML content, you could modify its CSP to allow connections to the target URL. This involves adding the target URL to the `connect-src` directive in the CSP header. However, this is not feasible if you do not control the page, and it's not a good practice to weaken the CSP of a page without a strong understanding of the security implications.


      ### Conclusion


      Due to the security implications and limitations of working around CSP, the most robust solution for a tool like this bookmarklet would likely involve using a server-side proxy that you control. This approach allows you to manage CORS and CSP issues centrally and securely. Remember, any solution that involves bypassing or weakening security measures like CSP should be carefully considered for its potential security implications.
