Frequently Asked Questions
What is the difference between standard mongodb:// and mongodb+srv:// URIs?
Standard mongodb:// URIs list individual replica set hostnames and port numbers explicitly. The mongodb+srv:// protocol uses DNS SRV records to discover replica set members dynamically, which simplifies cluster configuration in hosted services like MongoDB Atlas.
Are my database credentials stored or sent to a server?
No. All URI string concatenation, parameter encoding, and credential formatting execute entirely client-side in your web browser. Nothing is sent across the network.
How should special characters in database passwords be handled?
Special characters such as @, :, /, and % inside database usernames or passwords must be percent-encoded (URL encoded). This builder automatically encodes them to prevent connection errors.
