Documented steps
Run npm ping from a project or home directory with the target registry configured
npm ping sends a GET to <registry>/-/ping?write=true and verifies the response, confirming both connectivity and that your stored auth is accepted
On success it prints e.g. 'npm notice PING https://registry.npmjs.org/' then 'npm notice PONG <ms>'
On failure it prints an error such as E404 or E401 (e.g. '404 Not Found - GET http://foo.com/-/ping?write=true')
Specify a registry explicitly with: npm ping --registry=https://registry.npmjs.org
Use alongside npm whoami to distinguish a network/connectivity problem from an auth/token problem
Known gotchas
npm ping is unaware of workspaces
A PING/PONG result only proves the registry endpoint is reachable and your auth is accepted — it does not validate that you can publish (see npm access / npm owner for that)
If your configured registry does not implement the /-/ping endpoint, npm will error even though the registry is healthy
