This makes it so imports of ambient modules (e.g. `$app/environment` in
svelte, any virtual module in vite, or other module provided by a
bundler) don't error in the LSP.
The way this works is that when we request diagnostics from TSC, we also
respond with the list of ambient modules. Then, in the diagnostics code,
we save diagnostics (produced by deno) that may be invalidated as an
ambient module and wait to publish the diagnostics until we've received
the ambient modules from TSC.
The actual ambient modules you get from TSC can contain globs, e.g.
`*.css`. So when we get new ambient modules, we compile them all into a
regex and check erroring imports against that regex. Ambient modules
should change rarely, so in most cases we should be using a pre-compiled
regex, which executes in linear time (wrt the specifier length).
TODO:
- Ideally we should only publish once, right now we publish with the
filtered specifiers and then the TSC ones
- deno check (#27633)
This slightly degrades the performance of CJS export analysis on
subsequent runs because I changed it to no longer cache in the DENO_DIR
with this PR (denort now properly has no idea about the DENO_DIR). We'll
have to change it to embed this data in the binary and that will also
allow us to get rid of swc in denort (will do that in a follow-up PR).
Fixes #26224.
Fixes #27042.
There were three bugs here:
- we were only resolving `/// <reference types` directives starting with
`npm:`, which meant we failed to resolve bare specifiers (this broke the
`/// <reference types="vite/client">` directive in most of the vite
templates)
- the `$node_modules` workaround caused us to fail to read files for
tsc. For instance tsc would construct new paths based on specifiers
containing `$node_modules`, and since we hadn't created those we weren't
mapping them back to the original (this broke some type resolution
within `vite/client`)
- our separation of `ImportMeta` across node and deno globals in tsc
meant that npm packages couldn't augment `ImportMeta` (this broke
`vite/client`'s augmentation to add `import.meta.env` and others)
After this, the only remaining issue in the vanilla vite template is our
error on `/vite.svg` (which is an ambient module), and I'll look into
that next.
Fixes https://github.com/denoland/deno/issues/27062
In the LSP we were passing `npm` specifiers to TSC as roots, but TSC
needs fully resolved specifiers (like the actual file path).
In `deno check` we were often excluding the specifiers entirely from the
roots.
In both cases, we need to resolve the specifiers fully and then pass
them to tsc
Fixes https://github.com/denoland/deno/issues/25762. Note that some of
the things in that issue are not resolved (vite/client types not working
properly which has other root causes), but the wildcard module
augmentation specifically is fixed by this.
We were telling TSC that files with unknown media types had an extension
of `.js`, so the ambient module declarations weren't applying. Instead,
just don't resolve them, so the ambient declaration applies.
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));
```
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.
This replaces `--allow-net` for import permissions and makes the
security sandbox stricter by also checking permissions for statically
analyzable imports.
By default, this has a value of
`--allow-import=deno.land:443,jsr.io:443,esm.sh:443,raw.githubusercontent.com:443,gist.githubusercontent.com:443`,
but that can be overridden by providing a different set of hosts.
Additionally, when no value is provided, import permissions are inferred
from the CLI arguments so the following works because
`fresh.deno.dev:443` will be added to the list of allowed imports:
```ts
deno run -A -r https://fresh.deno.dev
```

This is for security reasons for the time being for Deno 2. Details to
follow post Deno 2.0 release.
Remote import maps seem incredibly rare (only 2 usages on GitHub from
what I can tell), so we'll add this back with more permissions if
there's enough demand for it:
https://github.com/search?type=code&q=%2F%22importMap%22%3A+%22http%2F
In the meantime, use the `--import-map` flag and `"deno.importMap"`
config in the LSP for remote import maps.
This commits stabilizes CSS, HTML and YAML formatters
in `deno fmt`.
It is no longer required to use either of these flags:
- `--unstable-css`
- `--unstable-html`
- `--unstable-yaml`
Or these `unstable` options in the config file:
- `fmt-css`
- `fmt-html`
- `html-yaml`
The long form "files" config has been flattened into the parent.
Old:
```json
{
"test": {
"files": {
"include": ["**/*.ts"],
"exclude": ["ignore.ts"]
}
}
}
```
New:
```json
{
"test": {
"include": ["**/*.ts"],
"exclude": ["ignore.ts"]
}
}
```
This was deprecated some time ago, but we're removing it now in Deno
2.0.
Closes #25415
