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`.
This commit removes conditional type-checking of unstable APIs.
Before this commit `deno check` (or any other type-checking command and
the LSP) would error out if there was an unstable API in the code, but not
`--unstable` flag provided.
This situation hinders DX and makes it harder to configure Deno. Failing
during runtime unless `--unstable` flag is provided is enough in this case.
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.
This commit adds a way to connect to the TS compiler host that is run
as part of the "deno lsp" subcommand. This can be done by specifying
"DENO_LSP_INSPECTOR" variable.

Adds performance measurements for all ops used by the LSP. Also changes
output of "Language server status" page to include more precise
information.
Current suspicion is that computing "script version" takes a long time
for some users.
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 commit changes LSP log names by prefixing them, we now have these
prefixes:
- `lsp.*` - requests coming from the client
- `tsc.request.*` - requests coming from clients that are routed to TSC
- `tsc.op.*` - ops called by the TS host
- `tsc.host.*` - requests that call JavaScript runtime that runs
TypeScript compiler host
Additionall `Performance::mark` was split into `Performance::mark` and
`Performance::mark_with_args` to reduce verbosity of code and logs.
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.
