die-with-stdin

This is a simple script that launches its argumets as child process and ensures the process is killed when parent stdin exits. It is similar to webpack's --watch-stdin but should be usable with any npm script (at least in theory).

Reason for being

This script has been created out of frustration with zombie processes left around when restarting Elixir/Phoenix dev instances. With this library any npm watcher script prefixed with die-with-stdin should exit correctly when phoenix is killed.

Usage

Install

npm install --save-dev die-with-stdin

Use

    ...,
    "scripts": {
        ...,
        "tailwind:dev": "die-with-stdin tailwindcss --input=css/app.css --output=../priv/static/assets/app.css --postcss --watch",
    },
    ...

Use with Phoenix

Edit config/dev.exs

config :your_project, YourProject.Endpoint,
  http: [port: 4000],
  debug_errors: true,
  code_reloader: true,
  check_origin: false,
  watchers: [
    esbuild: {Esbuild, :install_and_run, [:default, ~w(--sourcemap=inline --watch)]},
    npm: [
      "run",
      "dev:css",
      cd: Path.expand("../assets", __DIR__)
    ]
  ]
