Dev Browser
A CLI for controlling browsers with sandboxed JavaScript scripts.
Installation
npm install -g dev-browser dev-browser install
Usage
Run `dev-browser --help` to learn more.
Named daemon-launched browsers persist by default. For unattended work, `--idle-timeout 5m` closes each launched browser after inactivity while preserving its profile and login state. The setting never closes Chrome attached with `--connect`; use `--idle-timeout 0` to disable configured cleanup.
