feat(unstable): initial support for npm specifiers #15484

dsherret · 2022-08-16T22:21:32Z

This adds initial very rough support for npm specifiers for deno run, deno eval, and deno test.

Packages and their registry info are downloaded & cached to the deno dir. Reloading registry info can be done by using the --reload flag.
Node globals are limited to the npm packages. For example, this allows for the node code to use a different setTimeout implementation.
No type checking, lsp, deno run npm:mkdirp, deno info, deno vendor, or lockfile support yet. These will land in separate PRs.

Maybes before landing:

Analyzing the "native" node modules with deno graph is incredibly slow. The need to do this should be eliminated somehow.

Great work @dsherret !

I'm concerned about the deno_graph slowness, it's going to be pretty apparent to users.

cli/proc_state.rs

+
+ // add the builtin node modules to the graph data
+ let node_std_graph = self
+ .create_graph(vec![(compat::MODULE_ALL_URL.clone(), ModuleKind::Esm)])


The slowness is quite bad... it takes almost 2 seconds to load a very basic npm dependency that's already been downloaded.

+) -> Result<(), AnyError> {
+ let source_code = &format!(
+ r#"(async function loadBuiltinNodeModules(moduleAllUrl) {{
+ const moduleAll = await import(moduleAllUrl);


It's unfortunate that we have to load all of the node modules even if only some are used. Do you think in the future these could be loaded lazily?

Unlikely, these modules have a lot of cross-imports, so they would be loaded anyway

I'd push back on that assumption. I'm sure there are many npm modules that don't require, say, crypto.

+/// For all discovered reexports the analysis will be performed recursively.

would be great to have a little unit test for this...

There are integration tests that cover this API
