Human Idea

Today, on the Google Search Central, I learned about robots.txt. This file specifies which pages or files on our website search engine crawlers are allowed to access.

Following the instructions, I manually generated a robots.txt file and uploaded it to the website's root directory.

Although manually generating a robots.txt file isn't particularly troublesome, adhering to the spirit of "Human Ideas, Executed by AI." I decided to use AI to develop a robots.txt file generator.

Executed by AI

I opened Qoder, created a new project, and entered the following prompt:

Implement a robots.txt file generator using HTML5 with the following requirements:
1. The left side of the generator is a configuration panel for setting robots.txt parameters:
   - Sitemap URL setting
   - Search engine permissions settings (Google, Bing, Baidu)
   - Disallowed paths settings
   - Crawl delay setting
2. The right side of the generator is a preview panel that displays the generated robots.txt content in real-time.
3. Add quick actions below the preview panel:
   - One-click copy to clipboard
   - Direct download of the robots.txt file
4. Responsive design: Adapts to various screen sizes.

It was completed in about a minute.

Qoder added a button to generate the robots.txt file below the left configuration panel. Since the right panel of the generator is a real-time preview, this generate button is redundant and can be removed.

Qoder, by default, places HTML, script, and style code in separate files, which is good practice. However, for a small and elegant tool like a robots.txt file generator, we don't need that complexity; it can be merged into a single file.

I continued by entering the following prompt:

Continue improving this robots.txt file generator with the following requirements:
1. Remove the 'Generate robots.txt' button.
2. Merge the script and CSS code into the HTML file.

Excellent! It perfectly implemented my requirements. See the screenshot:

All features of the robots.txt file generator have been tested successfully, and it's ready to use!
