A modern runtime for JavaScript and TypeScript.

This commit adds a new subcommand called "coverage" which can generate code coverage reports to stdout in multiple formats from code coverage profiles collected to disk. Currently this supports outputting a pretty printed diff and the lcov format for interoperability with third-party services and tools. Code coverage is still collected via other subcommands that run and collect code coverage such as "deno test --coverage=<directory>" but that command no longer prints a pretty printed report at the end of a test run with coverage collection enabled. The restrictions on which files that can be reported on has also been relaxed and are fully controllable with the include and exclude regular expression flags on the coverage subcommand.

Deno
Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.
Features
- Secure by default. No file, network, or environment access, unless explicitly enabled.
- Supports TypeScript out of the box.
- Ships only a single executable file.
- Built-in utilities like a dependency inspector (deno info) and a code formatter (deno fmt).
- Set of reviewed standard modules that are guaranteed to work with Deno.
Install
Shell (Mac, Linux):
curl -fsSL https://deno.land/x/install/install.sh | sh
PowerShell (Windows):
iwr https://deno.land/x/install/install.ps1 -useb | iex
Homebrew (Mac):
brew install deno
Chocolatey (Windows):
choco install deno
Build and install from source using Cargo:
cargo install deno
See deno_install and releases for other options.
Getting Started
Try running a simple program:
deno run https://deno.land/std/examples/welcome.ts
Or a more complex one:
import { serve } from "https://deno.land/std/http/server.ts";
const s = serve({ port: 8000 });
console.log("http://localhost:8000/");
for await (const req of s) {
req.respond({ body: "Hello World\n" });
}
You can find a more in depth introduction, examples, and environment setup guides in the manual.
More in-depth info can be found in the runtime documentation.
