Automated JavaScript Console Execution

I am exploring ways to utilize Chrome’s developer tools effectively. My goal is to have any site that I open in Chrome automatically run a specific JavaScript snippet. For example, I would like it to execute the following line of code: console.log(‘hello world’) when I visit a page.

A solution that I’ve found helpful is using browser extensions like Tampermonkey or Violentmonkey. These extensions allow you to write and run user scripts automatically on page load. You can set it to trigger your JavaScript code when certain conditions are met, like loading specific URLs or generally on all pages. This method ensures that your console.log('hello world') will run seamlessly without requiring manual intervention each time. Just make sure to fine-tune your script settings and permissions within the extension for optimal performance and security.

Another approach to consider is using a bookmarklet. A bookmarklet is a small JavaScript program stored as the URL of a bookmark in a web browser. You can create one by saving a new bookmark and entering your JavaScript code as the URL prefixed by javascript:. Every time you visit a webpage, simply clicking on the bookmarklet will run your code. Although this requires a manual click, it’s a lightweight and browser-native solution that does not rely on third-party extensions.
