fix(install): re-setup bin entries after running lifecycle scripts (#26752)
Fixes #26677

Some packages (like supabase) declare bin entries that don't exist until
lifecycle scripts are run. For instance, the lifecycle script downloads
a binary file which serves as a bin entrypoint.

Unfortunately you can't just defer setting up the bin entries until
after lifecycle scripts have run, because the scripts may rely on them.

I looked into this, and PNPM just re-links bin entries after running
lifecycle scripts. I think that's about the best we can do as well.

Note that we'll only re-setup bin entries for packages whose lifecycle
scripts we run. This should limit the performance cost, as typically a
given project will not have many lifecycle scripts (and of those, many
of them probably don't have bin entries to set up).

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.
