Web Hosting
Confirm that this project has hosting that can continuously serve the site, then deploy it publicly. Do not treat localhost as live.

localhost:3000example.comDeployment sends a version there; the hosting environment keeps serving user requests afterward.
Hosting is the persistent environment: It stores static files or keeps a request-serving service running. When people use a public address, the environment returns the page or service result.
Deployment is the action that puts a version there: A deployment publishes one build or code version into the hosting environment. A successful build or a domain alone does not prove the public site serves the right version.
First confirm whether this project needs static file hosting or a continuously running service, then deploy it to the matching hosting environment. Request the page through its public URL and verify the new version rather than localhost; if it is still old, separate a hosting-environment issue from a deployment-version issue.
