Set up the SSL Certificates

Follow this instructions to configure a SSL certificate to serve NPM registry under HTTPS.

• Update the listen property in your ~/.config/verdaccio/config.yaml:

listen: 'https://your.domain.com/'

Once you update the listen and try to run verdaccio again will ask for certificates.

• Generate your certificates

 $ openssl genrsa -out ~/.config/verdaccio/verdaccio-key.pem 2048
 $ openssl req -new -sha256 -key ~/.config/verdaccio/verdaccio-key.pem -out ~/.config/verdaccio/verdaccio-csr.pem
 $ openssl x509 -req -in ~/.config/verdaccio/verdaccio-csr.pem -signkey ~/.config/verdaccio/verdaccio-key.pem -out ~/.config/verdaccio/verdaccio-cert.pem

• Edit your config file ~/.config/verdaccio/config.yalm an add the following section

https:
  key: ~/.config/verdaccio/server.key
  cert: ~/.config/verdaccio/server.crt
  ca: ~/.config/verdaccio/server.ca

• Run verdaccio in your command line.

• Open the browser and load https://your.domain.com:port/
