dev

#!/usr/bin/env bash
# Start the dev server on NixOS.
#
# Two things make a bare `yarn dev` fail here:
#   1. No node, npx, or real yarn on PATH. The ~/.local/bin/yarn shim execs npx
#      and dies with "exec: npx: not found".
#   2. node_modules/electron/dist/electron is a generic-linux prebuilt that NixOS
#      cannot execute. dev-runner calls require('electron') for the binary path,
#      and node_modules/electron/index.js honours ELECTRON_OVERRIDE_DIST_PATH, so
#      pointing that at the nixpkgs electron makes it spawn the wrapper instead.
#
# Usage: ./dev
