404 for NPM scoped packages

[daniel-shuy]

diligent doesn't work with NPM scoped packages (eg. @angular/cli).

This is because 44419b8 changed the NPM registry URL from https://registry.npmjs.org/{package}/{version} to https://registry.npmjs.org/{package}?version={version}, which for some weird reason doesn't support scoped packages, even if the slash (/) is URL encoded as %2F.

I've sent an email to NPM support about this behavior, but its unlikely that they will address it anytime soon.

To revert back to using https://registry.npmjs.org/{package}/{version}, we need to strip any symbols before the version, as https://registry.npmjs.org/{package}/{version} only supports exact versions, unlike https://registry.npmjs.org/{package}?version={version}.

Reply from NPM support:

As you may have found out already, the version query string parameter is no longer supported in our package APIs.
Even your https://registry.npmjs.org/base-64?version=%5E0.1.0 example just returns a list of all versions (same as https://registry.npmjs.org/base-64).

Therefore we shouldn't use https://registry.npmjs.org/{package}?version={version} anymore.
