Follow-up to cjs refactor.
This moves most of the resolution code into the deno_resolver crate.
Still pending is the npm resolution code.
|
|
package.json (#26439)
This will respect `"type": "commonjs"` in a package.json to determine if
`.js`/`.jsx`/`.ts`/.tsx` files are CJS or ESM. If the file is found to
be ESM it will be loaded as ESM though.
|
|
* cts support
* better cjs/cts type checking
* deno compile cjs/cts support
* More efficient detect cjs (going towards stabilization)
* Determination of whether .js, .ts, .jsx, or .tsx is cjs or esm is only
done after loading
* Support `import x = require(...);`

"commonjs"` (#26149)
When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
|
|
Some more slow progress on moving all the resolution code into
deno_resolver.
|
|
|
|
This is slow progress towards creating a `deno_resolver` crate.
Waiting on:
* https://github.com/denoland/deno/pull/25918
* https://github.com/denoland/deno/pull/25916

This was accidentally enabled in byonm, but it requires the
`--unstable-bare-node-builtins` flag.
Closes #25358
|
|
This commit adds support for executing top-level `.cjs` files,
as well as import `.cjs` files from within npm packages.
This works only for `.cjs` files, the contents of sibling `package.json`
are not consulted for the `"type"` field.
Closes https://github.com/denoland/deno/issues/25384

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.
|
|
|
|
|
|
Needed for https://github.com/denoland/deno/pull/25213.
With Deno 2, we should suggest using `deno install` instead of `npm
install`.

Adds a new `no-sloppy-imports` lint rule and cleans up the lint code.
Closes #22844

in error message (#24706)
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

workspace (#24611)
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.
* https://github.com/denoland/deno_config/pull/88
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.
|
|
(#24492)
Closes #16370
|
|
This will help clean up some of the code in the CLI because we'll be
able to tell how the resolution failed (not part of this PR).

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

Closes #18296.
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.

I've been meaning to fix this for ages, but I finally ran into it here:
https://github.com/dsherret/ts-ast-viewer/actions/runs/9432038675/job/25981325408
We need to resolve the `@types` package as a fallback instead of eagerly
resolving it.
|
|
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.

open (#23208)
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.

Our cjs tracking was a bit broken. It was marking stuff as esm that was
actually cjs leading to type checking errors.
|
|
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.
|
|
Changes the behaviour in Deno to just always load ES modules in npm
packages even if they're defined as CJS.
Closes #22818
|
|
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.

var (#22760)
An undocumented "DENO_DISABLE_PEDANTIC_NODE_WARNINGS" env
var can be used to silence warnings for sloppy imports and node builtins
without `node:` prefix.
|
|
We were missing saying that a file is CJS when some Deno code imported
from the node_modules directory at runtime.

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.
