This PR adds a new unstable "bring your own node_modules" (BYONM)
functionality currently behind a `--unstable-byonm` flag (`"unstable":
["byonm"]` in a deno.json).
This enables users to run a separate install command (ex. `npm install`,
`pnpm install`) then run `deno run main.ts` and Deno will respect the
layout of the node_modules directory as setup by the separate install
command. It also works with npm/yarn/pnpm workspaces.
For this PR, the behaviour is opted into by specifying
`--unstable-byonm`/`"unstable": ["byonm"]`, but in the future we may
make this the default behaviour as outlined in
https://github.com/denoland/deno/issues/18967#issuecomment-1761248941
This is an extremely rough initial implementation. Errors are
terrible in this and the LSP requires frequent restarts. Improvements
will be done in follow up PRs.
This makes `CliNpmResolver` a trait. The terminology used is:
- **managed** - Deno manages the node_modules folder and does an
auto-install (ex. `ManagedCliNpmResolver`)
- **byonm** - "Bring your own node_modules" (ex. `ByonmCliNpmResolver`,
which is in this PR, but unimplemented at the moment)
Part of #18967
TaskQueue is being removed from `deno_core` and replaced with an unsync
version in deno_unsyc.
https://github.com/denoland/deno_core/pull/193
This is a change in preparation for that. The remaining
`deno_core::TaskQueue` usage in this repo should be replaced with
`deno_core::unsync::TaskQueue` once upgraded.

To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:
- [x] Process stdin/stdout/stderr are lazily created
- [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

Rename some of the helper methods on the Fs trait to be suffixed with
`_sync` / `_async`, in preparation of the introduction of more async
methods for some helpers.
Also adds a `read_text_file_async` helper to complement the renamed
`read_text_file_sync` helper.
This commit moves `snapshot_from_lockfile` function to [deno_npm
crate](https://github.com/denoland/deno_npm). This allows this function
to be called outside Deno CLI (in particular, Deno Deploy).
Part of #19774. This makes it twice as fast on my machine.
Stores a file at `node_modules/.deno/setup-cache.bin`, which contains
information about how the node_modules folder is currently setup.
Obviously there is a risk that this information will get out of date
with the current folder structure.
This is what pnpm does and we were missing it. It makes modules work
which have a dependency on something, but don't say they have that
dependency, but that dep is still in the tree somewhere.
This adds support for the lockfile and node_modules directory to the
lsp.
In the case of the node_modules directory, it is only enabled when
explicitly opted into via `"nodeModulesDir": true` in the configuration
file. This is to reduce the language server automatically modifying the
node_modules directory when the user doesn't want it to.
Closes#16510Closes#16373
We never properly added support for this. This fixes vendoring when it
has npm or node specifiers. Vendoring occurs by adding a
`"nodeModulesDir": true` property to deno.json then it uses a local
node_modules directory. This can be opted out by setting
`"nodeModulesDir": false` or running with `--node-modules-dir=false`.
Closes#18090Closes#17210Closes#17619Closes#16778
Note: If the package information has already been cached, then this
requires running with `--reload` or for the registry information to be
fetched some other way (ex. the cache busting).

Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

This is the initial support for npm and node specifiers in `deno
compile`. The npm packages are included in the binary and read from it via
a virtual file system. This also supports the `--node-modules-dir` flag,
dependencies specified in a package.json, and npm binary commands (ex.
`deno compile --unstable npm:cowsay`)
Closes#16632
This commit changes how paths for npm packages are handled,
by canonicalizing them when resolving. This is done so that instead
of returning
"node_modules/<package_name>@<version>/node_modules/<dep>/index.js"
(which is a symlink) we "node_modules/<dep>@<dep_version>/index.js.

We can make `NodePermissions` rely on interior mutability (which the
`PermissionsContainer` is already doing) in order to not have to clone
everything all the time. This also reduces the chance of an accidental
`borrow` while `borrrow_mut`.
We were indeterministically including packages in the top level
`node_modules/` folder when using a local node_modules directory. This
change aligns with pnpm and only includes top level packages in this
folder. This should be faster for initializing the folder, but may
expose issues in packages that reference other packages not defined in
their dependencies. That said, the behaviour previously was previously
broken.
This has exposed a bug in the require implementation where it doesn't
find a package (which is the main underlying issue here). There is a
failing test already for this in the test suite after this change.
Closes#18822
