- Each workspace directory is probed for a `tsconfig.json`. - These and any that are included by their `references` are put into a list ordered by priority. - A tsconfig has lower priority than its `references`. - An earlier listed entry in `references` has higher priority than a later one. - A probed tsconfig in an inner directory has higher priority than an outer one. Their `references` would be interspersed between them. - Each tsconfig has a filter based on its `files`, `include` and `exclude` fields. If it doesn't have `files` or `include`, it will match any path in its containing directory not exempted by `exclude`. - For type-checking, each root path will be allocated compiler options based on the first tsconfig it whose filter it matches from this list. - Only if it doesn't match any tsconfig, it will fall back to using the nearest `deno.json`. If it's a workspace member and the root `deno.json` has `compilerOptions`, these will be merged using the same logic from `extends`. Inheritance between configs strictly occurs via `extends` in a `tsconfig.json`, and between workspace member and root `deno.json`s' `compilerOptions`. There is no implicit inheritance between `tsconfig.json` and `deno.json`. The default compiler options currently applied against tsconfigs are Deno's normal defaults, with the exception of `lib`. The default value for `lib` is `["deno.window", "deno.unstable", "dom"]` for files in the scope of a tsconfig with `lib` unspecified. This behaviour is depended on by, for example, the template project created by `create-vite -> svelte`. I expect we'll add more such exceptions over time with other fields. |

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 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.
