Will Deno’s approach to NPM compatibility support peer dependencies? https://nodejs.org/en/blog/npm/peer-dependencies/

Furthermore, will it support unifying transitive dependency versions to minimize bundle sizes?

Yes, this will be supported.

Hi Luca, can you provide a bit of detail on how this will be accomplished? Will Deno be analyzing an entire project’s npm imports simultaneously, rather than individually?

Deno already analyzes the entire module graph before the application starts up, so we extract out the npm specifiers ahead of time, do the npm dependency analysis, cache any packages as needed, then start execution.

Thanks. Any plans for supporting monorepos of first party NPM packages that teams already have?

We'll have custom registry support. For local npm packages, that would be nice to have, but probably something that will be implemented later. It could actually be done in a hacky way with the existing implementation of this we have, but it would be better to have something specifically designed for this.
