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 commit enables resolution of "bare specifiers" (eg. "import express
from 'express';") if a "package.json" file is discovered.
It's a step towards being able to run projects authored for Node.js
without any changes.
With this commit we are able to successfully run Vite projects without
any changes to the user code.

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.

The `NpmPackageId` struct is being renamed to `NpmPackageNodeId`. In a
future PR it will be moved down into only npm dependency resolution and
a `NpmPackageId` struct will be introduced in `deno_graph` that only has
the name and version of the package (no peer dependency identifier
information). So a `NpmPackageReq` will map to an `NpmPackageId`, which
will map to an `NpmPackageNodeId` in the npm resolution.
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 change makes absolute urls, that contain no path like `deno install
https://my-cli.io` to follow redirects and extract the name from it.
It allows modifies `test_util` server listener on port `4550`
(`REDIRECT_ABSOLUTE_PORT`) to allow for specifying `redirect_to` query
param, that fill use that value for it's next redirect.
Fixes https://github.com/denoland/deno/issues/17409
This commit changes handling of config file to enable
specifying "imports" and "scopes" objects effectively making
the configuration file an import map.
"imports" and "scopes" take precedence over "importMap" configuration,
but have lower priority than "--importmap" CLI flag.

Allows to change behavior of `deno fmt` to use "ASI" setting for
semicolons instead of always prefering them, this is done
by "--options-semi=asi" flag or `"semi": "asi"` setting
in the config file.
This change prints a link to the release notes to `deno upgrade` output
and its variations.
Release notes aren't printed for commands relating to canary versions.
Closes #16350.
The way the standalone mode handles the `--cert` flag is different to
all other modes. This is because `--cert` takes a path to the
certificate file, which is directly added to the root cert store; except
for compile mode, where its byte contents are stored in the standalone
metadata, and they are added to the root cert store after the
`ProcState` is created.
This change instead changes `Flags::ca_file` (an `Option<String>`) into
`Flags::ca_data`, which can represent a `String` file path or a
`Vec<u8>` with the certificate contents. That way, standalone mode can
create a `ProcState` whose root cert store alreay contains the
certificate.
This change also adds a tests for certificates in standalone mode, since
there weren't any before.
This refactor will help with implementing web workers in standalone mode
in the future.
This commit changes "ProcState" to store "file_fetcher" field in an "Arc",
allowing it to be preserved between restarts and thus keeping the state
alive between the restarts. File watchers for "deno test" and "deno bench"
now reset "ProcState" between restarts.
Turns out we were cloning permissions which after prompting were discarded,
so the state of permissions was never preserved. To handle that we need to store
all permissions behind "Arc<Mutex<>>" (because there are situations where we
need to send them to other thread).
Testing and benching code still uses "Permissions" in most places - it's undesirable
to share the same permission set between various test/bench files - otherwise
granting or revoking permissions in one file would influence behavior of other test
files.
The output of `init` are commands, so this should be treated as a "Shell
script". In Shell script, comments must start with `#`, not `//`. (This
also makes the commands example easier to be copied to somewhere.)
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.
This commit changes "deno repl" command to run with no permissions by
default and accept "--allow-*" flags.
This change is dictated by the fact that currently there is no way to
run REPL with limited permissions. Technically it's a breaking
change in the CLI command, but there's agreement in the team
that it has merit and it's a good solution.
Running just "deno" command still starts the REPL with full permissions
allowed, but now a banner is printed to inform users about that:
We currently only do this for fmt. This makes it so they're excluded by
default, but you can still opt into these directories by explicitly
specifying them.
With trial and error I found that most debuggers expect "isDefault" to be sent
in "auxData" field of "executionContextCreated" notification. This stems from
the fact that Node.js sends this data and eg. VSCode requires it to close
connection to the debugger when the program finishes execution.
This commit changes history handling of the REPL.
There were some situations were history wasn't properly saved and flushed to a
file, making history very spotty. This commit changes it to save every line into
the history file and flush it to disk before being evaluated.
Thanks to this all lines, including "close()" will be stored in the history
file.
If for any reason we're not able to save history file, a single warning will be
printed to the REPL and it will continue to work, even if subsequent tries will
fail to save to disk.
Supports npm specifiers for `deno install`. This will by default always
use a lockfile (which is generated on first run) unless `--no-lock` is
specified.
This adds support for peer dependencies in npm packages.
1. If not found higher in the tree (ancestor and ancestor siblings),
peer dependencies are resolved like a dependency similar to npm 7.
2. Optional peer dependencies are only resolved if found higher in the
tree.
3. This creates "copy packages" or duplicates of a package when a
package has different resolution due to peer dependency resolution—see
https://pnpm.io/how-peers-are-resolved. Unlike pnpm though, duplicates
of packages will have `_1`, `_2`, etc. added to the end of the package
version in the directory in order to minimize the chance of hitting the
max file path limit on Windows. This is done for both the local
"node_modules" directory and also the global npm cache. The files are
hard linked in this case to reduce hard drive space.
This is a first pass and the code is definitely more inefficient than it
could be.

`deno task` has been in use for a few months now. It was very
well received and there are not many complaints. I feel like
this warning might be discouraging for some users and we don't
really plan to make drastic changes to it (besides adding support
for globs in unspecified future).
This commit prevents panics that `deno compile` command ran into under certain
conditions from occurring. Such conditions are as follows.
- the target file name begins with `@`, OR
- the stem part of the target file name is equal to one of
["main", "index", "mod", "index"] && the parent directory name starts with `@`
Fixes #16243
Stop allowing clippy::derive-partial-eq-without-eq and fix warnings
about deriving PartialEq without also deriving Eq.
In one case I removed the PartialEq because it a) wasn't necessary,
and b) sketchy because it was comparing floating point numbers.
IMO, that's a good argument for enforcing the lint rule, because it
would most likely have been caught during review if it had been enabled.
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.
This adds an init subcommand to that creates a project starter similar to cargo init.
```
$ deno init my_project
Project initialized
Run these commands to get started:
cd my_project
deno run main.ts
deno run main_test.ts
$ deno run main.ts
Add 2 + 3 5
$ cat main.ts
export function add(a: number, b: number): number {
return a + b;
}
if (import.meta.main) {
console.log("Add 2 + 3", add(2, 3));
}
$ cat main_test.ts
import { assertEquals } from "https://deno.land/std@0.151.0/testing/asserts.ts";
import { add } from "./main.ts";
Deno.test(function addTest() {
assertEquals(add(2, 3), 5);
});

This commit changes default default behavior of type checking
for several subcommands.
Instead of type checking and reporting type errors only for local
files, the type checking is skipped entirely. Type checking can
still be enabled using the "--check" flag.
Following subcomands are affected:
- deno cache
- deno install
- deno eval
- deno run
This commit changes default mode of type-checking to "local"
and adds "--check" flag to following subcommands:
- deno bench
- deno bundle
- deno cache
- deno compile
- deno eval
- deno install
- deno test
This flag disables loading of configuration file, ie. it will not be
automatically discovered and loaded. Of course this flag conflicts
with "--config" flag and they cannot be used together.
This commit adds better reporting of uncaught errors
in top level scope of testing files. This change affects
both console runner as well as LSP runner.
This commit:
- removes "fmt_errors::PrettyJsError" in favor of "format_js_error" fn
- removes "deno_core::JsError::create" and
"deno_core::RuntimeOptions::js_error_create_fn"
- adds new option to "deno_runtime::ops::worker_host::init"
This commit changes "deno bench" subcommand, by updating
the "Deno.bench" API as follows:
- remove "Deno.BenchDefinition.n"
- remove "Deno.BenchDefintion.warmup"
- add "Deno.BenchDefinition.group"
- add "Deno.BenchDefintion.baseline"
This is done because bench cases are no longer run fixed amount
of iterations, but instead they are run until there is difference between
subsequent runs that is statistically insiginificant.
Additionally, console reporter was rewritten completely, to looks
similar to "hyperfine" reporter.
This commit adds support for "--eval-file" in "deno repl" subcommand.
This flag can be used to pass paths or URLs to files, that will be executed
on REPL startup. All files will be executed in the same context as the REPL
(ie. as "plain old scripts", not ES modules), sharing the global scope.
This feature allows to implement custom REPLs on top of Deno's REPL.
This commit changes "deno test" to filter out stack frames if it is beneficial to the user.
This is the case when there are stack frames coming from "internal" code
below frames coming from user code.

This commit rewrites test runner to send structured error data from JavaScript
to Rust instead of passing strings. This will allow to customize display of errors
in test report (which will be addressed in follow up commits).
The following transformations gradually faced by "JsError" have all been
moved up front to "JsError::from_v8_exception()":
- finding the first non-"deno:" source line;
- moving "JsError::script_resource_name" etc. into the first error stack
in case of syntax errors;
- source mapping "JsError::script_resource_name" etc. when wrapping
the error even though the frame locations are source mapped earlier;
- removing "JsError::{script_resource_name,line_number,start_column,end_column}"
entirely in favour of "js_error.frames.get(0)".
We also no longer pass a js-side callback to "core/02_error.js" from cli.
I avoided doing this on previous occasions because the source map lookups
were in an awkward place.
This commit changes "deno test" to better denote user output coming
from test cases.
This is done by printing "---- output ----" and "---- output end ----"
markers if an output is produced. The output from "console" and
"Deno.core.print" is captured, as well as direct writes to "Deno.stdout"
and "Deno.stderr".
To achieve that new APIs were added to "deno_core" crate, that allow
to replace an existing resource with a different one (while keeping resource
ids intact). Resources for stdout and stderr are replaced by pipes.

Following changes were done in this commit:
- remove "test" prefix before each test
- use gray color for "running N tests from ..." prompt
- use relative path or remote URL instead of full URL in "running N tests from ..." prompt
- in "failures" section, add file path/remote URL before the test name

This commit adds new "deno check" subcommand.
Currently it is an alias for "deno cache" with the difference that remote
modules don't emit TS diagnostics by default.
Prints warning for "deno run" subcommand if "--check" flag is not present
and there's no "--no-check" flag. Adds "DENO_FUTURE_CHECK" env
variable that allows to opt into new behavior now.
This commit adds "deno bench" subcommand and "Deno.bench()"
API that allows to register bench cases.
The API is modelled after "Deno.test()" and "deno test" subcommand.
Currently the output is rudimentary and bench cases and not
subject to "ops" and "resource" sanitizers.

This commit fixes CJS/ESM interop in compat mode for dynamically
imported modules.
"ProcState::prepare_module_load" was changed to accept a list
of "graph roots" without associated "module kind". That module kind
was always hardcoded to "ESM" which is not true for CJS/ESM interop -
a CommonJs module might be imported using "import()" function. In
such case the root of the graph should have "CommonJs" module kind
instead of "ESM".
This commit adds "--trace-ops" flag to "deno test" subcommand.
This flag enables saving of stack traces for async ops, that before were always
saved. While the feature proved to be very useful it comes with a significant performance
hit, it's caused by excessive source mapping of stack frames.
This commit improves the error messages for the `deno test` async op
sanitizer. It does this in two ways:
- it uses handwritten error messages for each op that could be leaking
- it includes traces showing where each op was started
This "async op tracing" functionality is a new feature in deno_core.
It likely has a significant performance impact, which is why it is only
enabled in tests.
This commit adds "--output" to "deno coverage" subcommand.
It can be used instead of piping output to a file.

Covered ranges were not merged and thus it appeared that some lines
might be uncovered. To fix this I used "v8-coverage" that takes care
of merging the ranges properly. With this change, coverage collected
from a file by multiple entrypoints is now correctly calculated.
I ended up forking https://github.com/demurgos/v8-coverage and adding
"cli/tools/coverage/merge.rs" and "cli/tools/coverage/range_tree.rs".
This commit changes "deno coverage" command not to type check.
Instead of relying on infrastructure for module loading in "deno run";
the code now directly reaches into cache for original and transpiled
sources. In case sources are not available the error is returned to the
user, suggesting to first run "deno test --coverage" command.
Fixes "op_set_exit_code" by sharing a single "Arc" between
all workers (via "op state") instead of having a "global" value stored in
"deno_runtime" crate. As a consequence setting an exit code is always
scoped to a tree of workers, instead of being overridable if there are
multiple worker tree (like in "deno test --jobs" subcommand).
Refactored "cli/main.rs" functions to return "Result<i32, AnyError>" instead
of "Result<(), AnyError>" so they can return exit code.
Previously just a generic "error: No such file or directory (os error
2)" was printed. Now "`unzip` was not found on your PATH, please install
`unzip`" will be printed.
This commit changes formatting of elapsed time in test
runner output.
Instead of "XXXms", reporter outputs one of:
- "XXXms" for <1000ms
- "XXs" for <60s
- "XXXmYYs" for >=60s
This commit fixes problem with LSP where diagnostics coming
from "deno lint" don't respect configuration file.
LSP was changed to store "Option<ConfigFile>", "Option<LintConfig>"
and "Option<FmtConfig>" on "Inner"; as well as storing "Option<LintConfig>"
and "Option<FmtConfig>" on "StateSnapshot".

This commit adds "--compat" flag. When the flag is passed a set of mappings for
built-in Node modules is injected into the import map. If user doesn't
explicitly provide an import map (using "--import-map" flag) then a map is
created on the fly. If there are already existing mappings in import map that
would clash with built-in Node modules a set of diagnostics is printed to the
terminal with suggestions how to proceed.
This commit fixes a problem where loading and executing multiple
modules leads to all of the having "import.meta.main" set to true.
Following Rust APIs were deprecated:
- deno_core::JsRuntime::load_module
- deno_runtime::Worker::execute_module
- deno_runtime::WebWorker::execute_module
Following Rust APIs were added:
- deno_core::JsRuntime::load_main_module
- deno_core::JsRuntime::load_side_module
- deno_runtime::Worker::execute_main_module
- deno_runtime::Worker::execute_side_module
- deno_runtime::WebWorker::execute_main_module
Trying to load multiple "main" modules into the runtime now results in an
error. If user needs to load additional "non-main" modules they should use
APIs for "side" module.
This commit adds support for configuration file for "deno fmt"
subcommand. It is also respected by LSP when formatting
files.
Example configuration:
{
"fmt": {
"files": {
"include": ["src/"],
"exclude": ["src/testdata/"]
},
"options": {
"useTabs": true,
"lineWidth": 80,
"indentWidth": 4,
"singleQuote": true,
"textWrap": "preserve"
}
}
}
This commit updated "deno_lint" crate to 0.15.1 and refactors
"cli/tools/lint.rs" to create only a single vector of lint rules,
instead of creating a vector for each linted file.
This commit refactors "DenoSubcommand" enum in a way that variants
no longer contain anonymous structures but instead contain
dedicated structures for each subcommand, eg. "DenoSubcommand::Lint"
now contains "LintSubcommand".
This commit adds support for following flags in deno lint subcommand:
--config - allows to load configuration file and parses "lint" object
--rules-tags=<tags> - allows specifying which set of tagged rules should be run
--rules-include=<rules> - allow specifying which rules should be run
--rules-exclude=<rules> - allow specifying which rules should not be run
This commit merges the two vectors of specifiers into a single one introducing
the concept of a "TestMode" which is a tri-state enum specifying how a specifier
is to be tested (as documentation, as an executable module or as both).
This is determined during the collection phase and determines how a specifier
will be executed based on how the specifier was collected (directly or not) and
if it has an eligible media_type when fetched.
For example "deno test README.md" is marked as documentation because, while it
is a direct inclusion it is not an executable media type therefore will only
have the fenced code blocks that can be parsed from it tested.
Normalizes the naming of the functions used to determine
if a path is a suitable match for the test runner and placed
them both in the the fs_util module.
