Internet access to the following public software repositories:

Internet access and corporate proxy servers
If you access the Internet via a corporate proxy that requires NTLM authentication, then possible solutions include:
Configure npm and Yarn to use an alternative proxy server, if one is available, that allows basic HTTP authentication for specific users and websites.
Configure npm and Yarn to use a local proxy (local to your development machine) that appends NTLM authentication headers before forwarding traffic to the main corporate proxy.
