using custom registry instead of registry.npmjs.org

In my org there is some issue and proxy is not available . my org promotes some virtual registry url that they have. How can i use that registry while doing expo init.

currently expo init throws error : request to https://registry.npmjs.org/expo-template-blank failed, reason: unable to get local issuer certificate

i need to change https://registry.npmjs.org/expo-template-blank to some custom url

it’s using registry configured in npm, you can change it with
npm config set registry https://your.org.registry/
