This allows using npm deps of jsr deps without having to add them to the
root package.json.
Works by taking the package requirement and scanning the
`node_modules/.deno` directory for the best matching package, so it
relies on deno's node_modules structure.
Additionally to make the transition from package.json to deno.json
easier, Deno now:
1. Installs npm deps in a deno.json at the same time as installing npm
deps from a package.json.
2. Uses the alias in the import map for `node_modules/<alias>` for
better package.json compatiblity.
Two small changes:
- In our BYONM errors, suggest running `deno install` instead of `npm
install` if `DENO_FUTURE` is set
- Only emit warning about `deno install` changes if you do `deno install
<foo>` with deno_future unset
This is in preparation for extracting out node resolution code from
ext/node (which is something I'm going to do gradually over time).
Uses https://github.com/denoland/deno_package_json
This makes bare specifiers for npm packages work when inside a
workspace, which emulates the same behaviour as when there's a
node_modules directory. The bare specifier can be overwritten by
specifying an import map entry or package.json dependency entry.

Closes #24605
This makes it easier to tell what kind of error something is (even for
deeply nested errors) and will help in the future once we add error
codes to the JS errors this returns.
Adds much better support for the unstable Deno workspaces as well as
support for npm workspaces. npm workspaces is still lacking in that we
only install packages into the root node_modules folder. We'll make it
smarter over time in order for it to figure out when to add node_modules
folders within packages.
This includes a breaking change in config file resolution where we stop
searching for config files on the first found package.json unless it's
in a workspace. For the previous behaviour, the root deno.json needs to
be updated to be a workspace by adding `"workspace":
["./path-to-pkg-json-folder-goes-here"]`. See details in
https://github.com/denoland/deno_config/pull/66

Adds a `--frozen` (alias `--frozen-lockfile`) flag that errors out if
the lockfile is out of date. This is useful for running in CI (where an
out of date lockfile is usually a mistake) or to prevent accidental
changes in dependencies.
Previously various reads of files in `node_modules` would error on
invalid UTF-8. These were cases involving:
- reading package.json from Rust
- reading package.json from JS
- reading CommonJS files from JS
- reading CommonJS files from Rust (for ESM translation)
- reading ESM files from Rust
Also removes permissions being passed in for node resolution. It was
completely useless because we only checked it for reading package.json
files, but Deno reading package.json files for resolution is perfectly
fine.
My guess is this is also a perf improvement because Deno is doing less
work.
Construct a new module graph container for workers instead of sharing it
with the main worker.

Embedders may have special requirements around file opening, so we add a
new `check_open` permission check that is called as part of the file
open process.
This PR enables V8 code cache for ES modules and for `require` scripts
through `op_eval_context`. Code cache artifacts are transparently stored
and fetched using sqlite db and are passed to V8. `--no-code-cache` can
be used to disable.

Was doing a bit of debugging on why some stuff is not working in a
personal project and ran a quick debug profile and saw it cloning the
pkg json a lot. We should put this in an Rc.
Previously the sloppy resolver could not resolve the following:
- foo/bar.ts
- foo.ts
- index.ts
Where `index.ts` contains `import "./foo"`, because it did not consider
`foo.ts` a valid target for this directory import.
This commit fixes this bug.
An undocumented "DENO_DISABLE_PEDANTIC_NODE_WARNINGS" env
var can be used to silence warnings for sloppy imports and node builtins
without `node:` prefix.
This introduces the `denort` binary - a slim version of deno without
tooling. The binary is used as the default for `deno compile`.
Improves `deno compile` final size by ~2.5x (141 MB -> 61 MB) on Linux
x86_64.
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 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.
