Supported Chrome command line switches

Following command lines switches in Chrome browser are also Supported in atom-shell, you can use app.commandLine.appendSwitch to append them in your app's main script before the ready event of app module is emitted:

var app = require('app');
app.commandLine.appendSwitch('remote-debugging-port', '8315');
app.commandLine.appendSwitch('host-rules', 'MAP * 127.0.0.1');

app.on('ready', function() {
});

--disable-http-cache

Disables the disk cache for HTTP requests.

--remote-debugging-port=port

Enables remote debug over HTTP on the specified port.

--proxy-server=address:port

Uses a specified proxy server, overrides system settings. This switch only affects HTTP and HTTPS requests.

--no-proxy-server

Don't use a proxy server, always make direct connections. Overrides any other proxy server flags that are passed.

--host-rules=rules

Comma-separated list of rules that control how hostnames are mapped.

For example:

• MAP * 127.0.0.1 Forces all hostnames to be mapped to 127.0.0.1
• MAP *.google.com proxy Forces all google.com subdomains to be resolved to "proxy".
• MAP test.com [::1]:77 Forces "test.com" to resolve to IPv6 loopback. Will also force the port of the resulting socket address to be 77.
• MAP * baz, EXCLUDE www.google.com Remaps everything to "baz", except for "www.google.com".

These mappings apply to the endpoint host in a net request (the TCP connect and host resolver in a direct connection, and the CONNECT in an http proxy connection, and the endpoint host in a SOCKS proxy connection).

--host-resolver-rules=rules

Like --host-rules but these rules only apply to the host resolver.

--ignore-certificate-errors

Ignore certificate related errors.
