This changes npm specifiers to be handled by deno_graph and resolved to an npm package name and version when the specifier is encountered. It also slightly changes how npm specifier resolution occurs—previously it would collect all the npm specifiers and resolve them all at once, but now it resolves them on the fly as they are encountered in the module graph. https://github.com/denoland/deno_graph/pull/232 --------- Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>
