This functionality was broken. The series of events was:
1. Load the npm resolution from the lockfile.
2. Discover only a subset of the specifiers in the documents.
3. Clear the npm snapshot.
4. Redo npm resolution with the new specifiers (~500ms).
What this now does:
1. Load the npm resolution from the lockfile.
2. Discover only a subset of the specifiers in the documents and take
into account the specifiers from the lockfile.
3. Do not redo resolution (~1ms).
Was investigating a separate stack overflow (that I've now found in the
node resolution code) and came across this. We should avoid recursion
(this is very old code).
1. Stops `deno publish` using some custom include/exclude behaviour from
other sub commands
2. Takes ancestor directories into account when resolving gitignore
3. Backards compatible change that adds ability to unexclude an exclude
by using a negated glob at a more specific level for all sub commands
(see https://github.com/denoland/deno_config/pull/44).
This changes the lockfile to not store JSR specifiers in the "remote"
section. Instead a single JSR integrity is stored per package in the
lockfile, which is a hash of the version's `x.x.x_meta.json` file, which
contains hashes for every file in the package. The hashes in this file
are then compared against when loading.
Additionally, when using `{ "vendor": true }` in a deno.json, the files
can be modified without causing lockfile errors—the checksum is only
checked when copying into the vendor folder and not afterwards
(eventually we should add this behaviour for non-jsr specifiers as
well). As part of this change, the `vendor` folder creation is not
always automatic in the LSP and running an explicit cache command is
necessary. The code required to track checksums in the LSP would have
been too complex for this PR, so that all goes through deno_graph now.
The vendoring is still automatic when running from the CLI.
This implementation heavily depends on there being a lockfile, meaning
JSR specifiers will always diagnose as uncached unless it's there. In
practice this affects cases where a `deno.json` isn't being used. Our
NPM specifier support isn't subject to this.
The reason for this is that the version constraint solving code is
currently buried in `deno_graph` and not usable from the LSP, so the
only way to reuse that logic is the solved-version map in the lockfile's
`packages.specifiers`.
We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
Adds an `--unstable-sloppy-imports` flag which supports the
following for `file:` specifiers:
* Allows writing `./mod` in a specifier to do extension probing.
- ex. `import { Example } from "./example"` instead of `import { Example
} from "./example.ts"`
* Allows writing `./routes` to do directory extension probing for files
like `./routes/index.ts`
* Allows writing `./mod.js` for *mod.ts* files.
This functionality is **NOT RECOMMENDED** for general use with Deno:
1. It's not as optimal for perf:
https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-2/
1. It makes tooling in the ecosystem more complex in order to have to
understand this.
1. The "Deno way" is to be explicit about what you're doing. It's better
in the long run.
1. It doesn't work if published to the Deno registry because doing stuff
like extension probing with remote specifiers would be incredibly slow.
This is instead only recommended to help with migrating existing
projects to Deno. For example, it's very useful for getting CJS projects
written with import/export declaration working in Deno without modifying
module specifiers and for supporting TS ESM projects written with
`./mod.js` specifiers.
This feature will output warnings to guide the user towards correcting
their specifiers. Additionally, quick fixes are provided in the LSP to
update these specifiers:
This PR causes Deno to include more files in the graph based on how a
template literal looks that's provided to a dynamic import:
```ts
const file = await import(`./dir/${expr}`);
```
In this case, it will search the `dir` directory and descendant
directories for any .js/jsx/etc modules and include them in the graph.
To opt out of this behaviour, move the template literal to a separate
line:
```ts
const specifier = `./dir/${expr}`
const file = await import(specifier);
```
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.
Some people might get think they need to import from this directory,
which could cause confusion and duplicate dependencies. Additionally,
the `vendor` directory has special behaviour in the language server, so
importing from the folder will definitely cause confusion and issues
there.
Renames the unstable `deno_modules` directory and corresponding settings
to `vendor` after feedback. Also causes the vendoring of the
`node_modules` directory which can be disabled via
`--node-modules-dir=false` or `"nodeModulesDir": false`.
This prevents documents specified in a deno.json's "exclude" from being
pre-loaded by the lsp.
For example, someone may have something like:
```jsonc
// deno.json
{
"exclude": [
"dist" // build directory
]
}
```
Rather than disallowing `ext:` resolution, clear the module map after
initializing extensions so extension modules are anonymized. This
operation is explicitly called in `deno_runtime`. Re-inject `node:`
specifiers into the module map after doing this.
Fixes #17717.
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 #16510
Closes #16373
Adds a `deno.preloadLimit` option (ex. `"deno.preloadLimit": 2000`)
which specifies how many file entries to traverse on the file system
when the lsp loads or its configuration changes.
Closes #18955
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
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`.
This is just a straight refactor and I didn't do any cleanup in
ext/node. After this PR we can start to clean it up and make things
private that don't need to be public anymore.
1. Breaks up functionality within `ProcState` into several other structs
to break out the responsibilities (`ProcState` is only a data struct
now).
2. Moves towards being able to inject dependencies more easily and have
functionality only require what it needs.
3. Exposes `Arc<T>` around the "service structs" instead of it being
embedded within them. The idea behind embedding them was to reduce the
verbosity of needing to pass around `Arc<...>`, but I don't think it was
exactly working and as we move more of these structs to be more
injectable I don't think the extra verbosity will be a big deal.
1. Fixes a cosmetic issue in the repl where it would display lsp warning
messages.
2. Lazily loads dependencies from the package.json on use.
3. Supports using bare specifiers from package.json in the REPL.
Closes #17929
Closes #18494
These methods are confusing because the arguments are backwards. I feel
like they should have never been added to `Option<T>` and that clippy
should suggest rewriting to
`map(...).unwrap_or(...)`/`map(...).unwrap_or_else(|| ...)`
https://github.com/rust-lang/rfcs/issues/1025
This has been bothering me for a while and it became more painful while
working on #18136 because injecting the shared progress bar became very
verbose. Basically we should move the creation of all these npm structs
up to a higher level.
This is a stepping stone for a future refactor where we can improve how
we create all our structs.
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 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 commits adds auto-discovery of "package.json" file when running
"deno run" and "deno task" subcommands. In case of "deno run" the
"package.json" is being looked up starting from the directory of the
script that is being run, stopping early if "deno.json(c)" file is found
(ie. FS tree won't be traversed "up" from "deno.json").
When "package.json" is discovered the "--node-modules-dir" flag is
implied, leading to creation of local "node_modules/" directory - we
did that, because most tools relying on "package.json" will expect
"node_modules/" directory to be present (eg. Vite). Additionally
"dependencies" and "devDependencies" specified in the "package.json"
are downloaded on startup.
This is a stepping stone to supporting bare specifier imports, but
the actual integration will be done in a follow up commit.
