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) |

Deno
Deno
(/ˈdiːnoʊ/, pronounced
dee-no
) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on V8,
Rust, and Tokio.
Learn more about the Deno runtime in the documentation.
Installation
Install the Deno runtime on your system using one of the commands below. Note that there are a number of ways to install Deno - a comprehensive list of installation options can be found here.
Shell (Mac, Linux):
curl -fsSL https://deno.land/install.sh | sh
PowerShell (Windows):
irm https://deno.land/install.ps1 | iex
Homebrew (Mac):
brew install deno
Chocolatey (Windows):
choco install deno
WinGet (Windows):
winget install --id=DenoLand.Deno
Build and install from source
Complete instructions for building Deno from source can be found in the manual here.
Your first Deno program
Deno can be used for many different applications, but is most commonly used to
build web servers. Create a file called server.ts
and include the following
TypeScript code:
Deno.serve((_req: Request) => {
return new Response("Hello, world!");
});
Run your server with the following command:
deno run --allow-net server.ts
This should start a local web server on http://localhost:8000.
Learn more about writing and running Deno programs in the docs.
