The Wayback Extension searches the Internet Archive Wayback Machine for snapshots of your current page, then displays the content via direct replacement or "diff-like" highlighting.

Thank you to Florian Ragwitz for helping me out with this!

Within the options folder you can change the following:

• Default Highlighting Colors
• Default Date Ranges For Different urls.
  • By default no configuration will be applied. Configurations must follow the following format:

  {
    "https://www.cdc.gov/.*":  //Regex expression of URL to match
    {
      "start": 20250101, //Jan 1st 2025 default start (YYYYmmDD)
      "end": 20250801 //August 1st 2025 default end (YYYYmmDD)
    },
    "https://www.google.com/.*":  //Regex expression of URL to match
    {
      "start": 19950101, //Jan 1st 1995 default start (YYYYmmDD)
      "end": 20230801 //August 1st 2023 default end (YYYYmmDD)
    }
  }

  • If multiple expressions match a URL, there is no set rule which will determine which one to apply.

• Download it from the Google Chrome Web Store
• Build the extension yourself:
  • npm run build should create a build folder.

• This project was bootstrapped with Chrome Extension CLI
• Run npm install to get all the necessary packages
• Run npm run watch to setup webpack
• Run web-ext run --target=chromium --source-dir ./build to open up a Chrome Session that will auto-refresh the extension for you
