How Web Developers Can Use BDU to Switch from Localhost to Production

If you're a web developer, you know how frustrating it is to test dozens of different links every day. You probably have a dedicated folder on your browser full of URLs pointing to http://localhost:3000 or http://127.0.0.1:8000.

You've saved admin pages, specific user profile paths, and maybe test deep-links for APIs. Everything works perfectly until it's time to test in staging or production.

The Environment Switch Problem#

To test the exact same route on the staging server, you find yourself clicking on the local bookmark, waiting for it to load, manually deleting localhost:3000 from the address bar, and typing staging.my-project.com. When you have to do this for 30 or 40 different routes throughout the day, the wasted time (and frustration) really adds up.

The Workflow with Bookmark Domain Updater#

With BDU, this problem vanishes. You can create a fluid testing environment right within your bookmarks:

  1. Save all your work bookmarks under a folder named "Project XYZ". Initially, these will point to localhost.
  2. When the project is pushed to staging, open the BDU extension.
  3. Enter localhost:3000 in the search field, and staging.my-project.com in the replacement field.
  4. Click Update. Boom.

In a tenth of a second, all your development bookmarks now point to the staging server while keeping paths, parameters, and queries intact.

Regex Power!#

If you have dynamic environments (e.g., pr-123.staging.project.com), you can use our Regex feature to handle complex patterns and update the entire link structure in a few clicks.

Being a web developer means automating anything repetitive. Stop manually editing URLs in the address bar and let BDU manage your environments!
