Chrome Launcher

This Elixir library makes launching headless Google Chrome processes with custom options easily.

Utilizes erlexec to manage processes under the hood.

Only supports OSX + Linux at this time.

Installation:

{:chrome_launcher, "~> 0.0.4"}

Usage:

{:ok, pid} = ChromeLauncher.launch([
  remote_debugging_port: 9233
])

Or in a supervisor (1.5+)

children = [
  {ChromeLauncher, [remote_debugging_port: 9222]}
]

Supervisor.start_link(children, strategy: :one_for_one)

With multiple instances in a supervisor (1.5+)

children = [
  Supervisor.child_spec({ChromeLauncher, [remote_debugging_port: 9222]}, id: :chrome_1),
  Supervisor.child_spec({ChromeLauncher, [remote_debugging_port: 9223]}, id: :chrome_2),
]

Supervisor.start_link(children, strategy: :one_for_one)

Pre 1.5

import Supervisor.Spec

children = [
  worker(ChromeLauncher, [[remote_debugging_port: 9222]], id: :chrome_1),
  worker(ChromeLauncher, [[remote_debugging_port: 9223]], id: :chrome_2),
]

Supervisor.start_link(children, strategy: :one_for_one)

Available options:

• remote_debugging_port: Configures --remote-debugging-port=PORT flag for connecting to the chrome process.
• flags: Flags to be passed in when starting the headless chrome process. (Overrides defaults set by :chrome_launcher)
