This removes the `moduleGraphX` data from the `<version>_meta.json`
files for jsr packages when copying from the global cache to the local
one. This property is not really useful to vendor because it's just a
performance optimization when downloading the files and someone may be
changing the data in the files leading to the `moduleGraph` data to be
out of date.
This commit adds "deno_features" crate that contains definitions of all
unstable features in Deno.
Based on these definitions, both Rust and JS code is generated ensuring
that the two are always in sync.
In addition some of flag handling was rewritten to use the generated
definitions, instead of hand rolling these flag definitions.

Apparently things like the `bin` field can appear in the version info
from the registry, but not the package's `package.json`. I'm still not
sure how you actually achieve this, but it's the case for
`esbuild-wasm`. This fixes the following panic:
```
❯ deno i --node-modules-dir npm:esbuild-wasm
Add npm:esbuild-wasm@0.25.2
Initialize ⣯ [00:00]
- esbuild-wasm@0.25.2

Fixes#27264. Fixes https://github.com/denoland/deno/issues/28161.
Currently the new lockfile version is gated behind an unstable flag
(`--unstable-lockfile-v5`) until the next minor release, where it will
become the default.
The main motivation here is that it improves startup performance when
using the global cache or `--node-modules-dir=auto`.
In a create-next-app project, running an empty file:
```
❯ hyperfine --warmup 25 -N --setup "rm -f deno.lock" "deno run --node-modules-dir=auto -A empty.js" "deno-this-pr run --node-modules-dir=auto -A empty.js" "deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js" "deno run --node-modules-dir=manual -A empty.js" "deno-this-pr run --node-modules-dir=manual -A empty.js"
Benchmark 1: deno run --node-modules-dir=auto -A empty.js
Time (mean ± σ): 247.6 ms ± 1.7 ms [User: 228.7 ms, System: 19.0 ms]
Range (min … max): 245.5 ms … 251.5 ms 12 runs
Benchmark 2: deno-this-pr run --node-modules-dir=auto -A empty.js
Time (mean ± σ): 169.8 ms ± 1.0 ms [User: 152.9 ms, System: 17.9 ms]
Range (min … max): 168.9 ms … 172.5 ms 17 runs
Benchmark 3: deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js
Time (mean ± σ): 16.2 ms ± 0.7 ms [User: 12.3 ms, System: 5.7 ms]
Range (min … max): 15.2 ms … 19.2 ms 185 runs
Benchmark 4: deno run --node-modules-dir=manual -A empty.js
Time (mean ± σ): 16.2 ms ± 0.8 ms [User: 11.6 ms, System: 5.5 ms]
Range (min … max): 14.9 ms … 19.7 ms 187 runs
Benchmark 5: deno-this-pr run --node-modules-dir=manual -A empty.js
Time (mean ± σ): 16.0 ms ± 0.9 ms [User: 12.0 ms, System: 5.5 ms]
Range (min … max): 14.8 ms … 22.3 ms 190 runs
Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
Summary
deno-this-pr run --node-modules-dir=manual -A empty.js ran
1.01 ± 0.08 times faster than deno run --node-modules-dir=manual -A empty.js
1.01 ± 0.07 times faster than deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js
10.64 ± 0.60 times faster than deno-this-pr run --node-modules-dir=auto -A empty.js
15.51 ± 0.88 times faster than deno run --node-modules-dir=auto -A empty.js
```
When using the new lockfile version, this leads to a 15.5x faster
startup time compared to the current deno version.
Install times benefit as well, though to a lesser degree.
`deno install` on a create-next-app project, with everything cached
(just setting up node_modules from scratch):
```
❯ hyperfine --warmup 5 -N --prepare "rm -rf node_modules" --setup "rm -rf deno.lock" "deno i" "deno-this-pr i" "deno-this-pr i --unstable-lockfile-v5"
Benchmark 1: deno i
Time (mean ± σ): 464.4 ms ± 8.8 ms [User: 227.7 ms, System: 217.3 ms]
Range (min … max): 452.6 ms … 478.3 ms 10 runs
Benchmark 2: deno-this-pr i
Time (mean ± σ): 368.8 ms ± 22.0 ms [User: 150.8 ms, System: 198.1 ms]
Range (min … max): 344.8 ms … 397.6 ms 10 runs
Benchmark 3: deno-this-pr i --unstable-lockfile-v5
Time (mean ± σ): 211.9 ms ± 17.1 ms [User: 7.1 ms, System: 177.2 ms]
Range (min … max): 191.3 ms … 233.4 ms 10 runs
Summary
deno-this-pr i --unstable-lockfile-v5 ran
1.74 ± 0.17 times faster than deno-this-pr i
2.19 ± 0.18 times faster than deno i
```
With lockfile v5, a 2.19x faster install time compared to the current
deno.
Deno.serve `Request` abort signals are aborted by default even when it
is finished successfully. This PR gates this behavior behind the
"legacy_abort" which is the default right now.
Turning the `no_legacy_abort` runtime option on is a **breaking change**
and will only abort request signals when there is a failure, thereby
cannot be used to determine if the request finished. This aligns with
`fetch` API.
Ref https://github.com/denoland/deno/issues/27005
This adds support for using a local copy of an npm package.
```js
// deno.json
{
"patch": [
"../path/to/local_npm_package"
],
// required until Deno 2.3, but it will still be considered unstable
"unstable": ["npm-patch"]
}
```
1. Requires using a node_modules folder.
2. When using `"nodeModulesDir": "auto"`, it recreates the folder in the
node_modules directory on each run which will slightly increase startup
time.
3. When using the default with a package.json (`"nodeModulesDir":
"manual"`), updating the package requires running `deno install`. This
is to get the package into the node_modules directory of the current
workspace. This is necessary instead of linking because packages can
have multiple "copy packages" due to peer dep resolution.
Caveat: Specifying a local copy of an npm package or making changes to
its dependencies will purge npm packages from the lockfile. This might
cause npm resolution to resolve differently and it may end up not using
the local copy of the npm package. It's very difficult to only
invalidate resolution midway through the graph and then only rebuild
that part of the resolution, so this is just a first pass that can be
improved in the future. In practice, this probably won't be an issue for
most people.
Another limitation is this also requires the npm package name to exist
in the registry at the moment.
This commit adds an unstable lint plugin API.
Plugins are specified in the `deno.json` file under
`lint.plugins` option like so:
```
{
"lint": {
"plugins": [
"./plugins/my-plugin.ts",
"jsr:@deno/lint-plugin1",
"npm:@deno/lint-plugin2"
]
}
}
```
The API is considered unstable and might be subject
to changes in the future.
Plugin API was modelled after ESLint API for the
most part, but there are no guarantees for compatibility.
The AST format exposed to plugins is closely modelled
after the AST that `typescript-eslint` uses.
Lint plugins use the visitor pattern and can add
diagnostics like so:
```
export default {
name: "lint-plugin",
rules: {
"plugin-rule": {
create(context) {
return {
Identifier(node) {
if (node.name === "a") {
context.report({
node,
message: "should be b",
fix(fixer) {
return fixer.replaceText(node, "_b");
},
});
}
},
};
},
},
},
} satisfies Deno.lint.Plugin;
```
Besides reporting errors (diagnostics) plugins can provide
automatic fixes that use text replacement to apply changes.

This PR adds the `--permit-no-files` cli options to the `bench`
subcommand. This will cause `deno bench --permit-no-files` to not return
an error when no bench files where found.
Allows easily constructing a `DenoResolver` using the exact same logic
that we use in the CLI (useful for dnt and for external bundlers). This
code is then used in the CLI to ensure the logic is always up-to-date.
```rs
use std::rc::Rc;
use deno_resolver:🏭:ResolverFactory;
use deno_resolver:🏭:WorkspaceFactory;
use sys_traits::impls::RealSys;
let sys = RealSys;
let cwd = sys.env_current_dir()?;
let workspace_factory = Rc::new(WorkspaceFactory::new(sys, cwd, Default::default()));
let resolver_factory = ResolverFactory::new(workspace_factory.clone(), Default::default());
let deno_resolver = resolver_factory.deno_resolver().await?;
```
This slightly degrades the performance of CJS export analysis on
subsequent runs because I changed it to no longer cache in the DENO_DIR
with this PR (denort now properly has no idea about the DENO_DIR). We'll
have to change it to embed this data in the binary and that will also
allow us to get rid of swc in denort (will do that in a follow-up PR).
Working on loading plugin configuration for
https://github.com/denoland/deno/pull/27203
I encountered a lot of complexity, so did some drive-by cleanups to make
it easier to grok the code and have fewer duplicate names.
split up otel config into user configurable and runtime configurable
parts. user configurable part is now set via env vars parsed according
to the otel spec. otel is now enabled via `OTEL_DENO=true`, and
`--unstable-otel` only acts as a guard.
Fixes: https://github.com/denoland/deno/issues/27273
Currently deno eagerly caches all npm packages in the workspace's npm
resolution. So, for instance, running a file `foo.ts` that imports
`npm:chalk` will also install all dependencies listed in `package.json`
and all `npm` dependencies listed in the lockfile.
This PR refactors things to give more control over when and what npm
packages are automatically cached while building the module graph.
After this PR, by default the current behavior is unchanged _except_ for
`deno install --entrypoint`, which will only cache npm packages used by
the given entrypoint. For the other subcommands, this behavior can be
enabled with `--unstable-npm-lazy-caching`
Fixes#25782.

Extracting out more code from the CLI for reuse elsewhere (still more
work to do, but this is a start).
This is the code for extracting npm tarballs and saving information in
the npm cache in the global deno_dir.
This resurrects the `--unstable-detect-cjs` flag (which became stable),
and repurposes it to attempt loading .js/.jsx/.ts/.tsx files as CJS in
the following additional scenarios:
1. There is no package.json
1. There is a package.json without a "type" field
Also cleans up the implementation of this in the LSP a lot by hanging
`resolution_mode()` off `Document` (didn't think about doing that until
now).
This commit adds support for `deno init --npm <package>`.
Running this will actually call to `npm:create-<package>` package that
is equivalent to running `npm create <package>`.
User will be prompted if they want to allow all permissions and
lifecycle scripts to be executed.
Closes https://github.com/denoland/deno/issues/26461

Closes#20487
Currently spelled
```
deno outdated
```
and
```
deno outdated --update
```
Works across package.json and deno.json, and in workspaces.
There's a bit of duplicated code, I'll refactor to reduce this in follow
ups
## Currently supported:
### Printing outdated deps (current output below which basically mimics
pnpm, but requesting feedback / suggestions)
```
deno outdated
```
### Updating deps
semver compatible:
```
deno outdated --update
```
latest:
```
deno outdated --latest
```
current output is basic, again would love suggestions
#### Filters
```
deno outdated --update "@std/*"
deno outdated --update --latest "@std/* "!@std/fmt"
```
#### Update to specific versions
```
deno outdated --update @std/fmt@1.0.2 @std/cli@^1.0.3
```
### Include all workspace members
```
deno outdated --recursive
deno outdated --update --recursive
```
## Future work
- interactive update
- update deps in js/ts files
- better support for transitive deps
Known issues (to be fixed in follow ups):
- If no top level dependencies have changed, we won't update transitive
deps (even if they could be updated)
- Can't filter transitive deps, or update them to specific versions
## TODO (in this PR):
- ~~spec tests for filters~~
- ~~spec test for mixed workspace (have tested manually)~~
- tweak output
- suggestion when you try `deno update`

This commit improves permission prompts by adding an option
to print a full trace of where the permissions is being requested.
Due to big performance hint of stack trace collection, this is only
enabled when `DENO_TRACE_PERMISSIONS` env var is present.

Support for Wasm modules.
Note this implements the standard where the default export is the
instance (not the module). The module will come later with source phase
imports.
```ts
import { add } from "./math.wasm";
console.log(add(1, 2));
```
Closes#26425
## Overview
This PR adds support for specifying multiple environment files as
arguments when using the Deno CLI. Subsequent files override
pre-existing variables defined in previous files.
If the same variable is defined in the environment and in the file, the
value from the environment takes precedence.
## Example Usage
```bash
deno run --allow-env --env-file --env-file=".env.one" --env-file=".env.two" script.ts
```
