Moving some code around in `ext/node` is it's a bit better well defined
and makes it possible for others to embed it.
I expect to see no difference in startup perf with this change.
This lazily does an "npm install" when any package name matches what's
found in the package.json or when running a script from package.json
with deno task.
Part of #17916
Closes #17928
This is a super basic initial implementation. We don't create a
`node_modules/.bin` folder at the moment and add it to the PATH like we
should which is necessary to make command name resolution in the
subprocess work properly (ex. you run a script that launches another
script that then tries to launch an "npx command"... this won't work
atm).
Closes #17492
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.

This PR fixes peer dependency resolution to only resolve peers based on
the current graph traversal path. Previously, it would resolve a peers
by looking at a graph node's ancestors, which is not correct because
graph nodes are shared by different resolutions.
It also stores more information about peer dependency resolution in the
lockfile.
This PR changes Node.js/npm compatibility layer to use polyfills for
built-in Node.js
embedded in the snapshot (that are coming from "ext/node" extension).
As a result loading `std/node`, either from
"https://deno.land/std@<latest>/" or
from "DENO_NODE_COMPAT_URL" env variable were removed. All code that is
imported via "npm:" specifiers now uses code embedded in the snapshot.
Several fixes were applied to various modules in "ext/node" to make
tests pass.

This commit moves some code around from "cli/node/mod.rs" to
"ext/node". Additionally "ext/node" was changed to factor out
"ops.rs" and "polyfill.rs" modules.
This commit does preparatory work to allow snapshotting Node.js
compatibility layer, that currently lives in `std/node`. The logic was
changed to allow loading some modules from the snapshot and
some from the remote URL.
Additionally "module_es_shim.js" that provides exports for "node:module"
is now snapshotted.
This commit changes signature of "deno_core::ModuleLoader::resolve" to pass
an enum indicating whether or not we're resolving a specifier for dynamic import.
Additionally "CliModuleLoader" was changes to store both "parent permissions" (or
"root permissions") as well as "dynamic permissions" that allow to check for permissions
in top-level module load an dynamic imports.
Then all code paths that have anything to do with Node/npm compat are now checking
for permissions which are passed from module loader instance associated with given
worker.
In our `require()` implementation we use a special logic to resolve
"base path" when looking for matching packages, however this logic
is in contradiction to what needs to happen if there's a local
"node_modules"
directory used. This commit changes require implementation to be aware
if we're running off of global node modules cache or a local one.
For CommonJS packages we were not trying different extensions for files
specified as subpath of the package ([package_name]/[subpath]).
This commit fixes that.
If resolving types for an npm package, we didn't find "types" entry in
the conditional exports declaration we were falling-through to regular
resolution, instead of short-circuiting and giving up on resolving
types, which might lead to unwarranted errors.

This commit adds a cache for CJS and ESM analysis that is backed by an
SQLite file.
The connection to the DB is lazily created on first use, so shouldn't
have impact on the startup time.

Changes how built-in Node modules are mapped to polyfills
from "deno_std". Instead of intertwining this logic into Node
resolution logic, we map them to "NodeResolution::BuiltIn"
which are remapped to "deno_std" URLs in ProcState.
- move errors related to Node compat from cli/node/errors.rs to "ext/node" crate
- remove dependency on "node_resolver" crate
- make some of structures private to the "cli/node" module
This commit removes "compat" mode. We shipped support for "npm:" specifier
support in v1.25 and that is preferred way to interact with Node code that we
will iterate and improve upon.
