The Chrome command line switch supported by Electron

This page lists the command line switches supported by Chrome and Electron. You can also use app.commandLine.appendSwitch to add them to your app's main script before the app module's ready event is issued:

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

app.on('ready', function() {
  // Your code here
});

--client-certificate= `path`

Set the client's certificate file path .

--ignore-connections-limit= `domains`

Ignore connection , with domains lists.

--disable-http-cache

Disk caching is prohibited when requesting HTTP.

--remote-debugging-port= `port`

Turn on remote 端口 via HTTP on the specified port.

--js-flags= `flags`

Specify the engine to transition to the JS engine.

When You start Electron, if you want to activate flags in the flags it will be converted.

$ electron --js-flags="--harmony_proxies --harmony_collections" your-app

--proxy-server= `address:port`

With a specific proxy server, it will take precedence over the system settings. T his switch is only valid when using the HTTP protocol and contains HTTPS and WebSocket requests. It is important to note that not all proxy servers support HTTPS and WebSocket requests.

--proxy-bypass-list= `hosts`

Let Electron use the proxy server for the semi-colon-separated hosts list provided by (se: bypass). This switch is only valid --proxy-server

For example:

app.commandLine.appendSwitch('proxy-bypass-list', '<local>;*.google.com;*foo.com;1.2.3.4:5678')

A proxy server will be used for all hosts except the local localhost , 127.0.0.1 etc.), google.com sub-domains, foo.com and all similar 1.2.3.4:5678

--proxy-pac-url= `url`

Use the url on the specified url.

--no-proxy-server

Do not use proxy services and always use direct connections. Ignore all reasonable agent flags.

--host-rules= `rules`

A comma-separated rule controls how host names are mapped.

For example:

MAP * 127.0.0.1 host names to map to 127.0.0.1
MAP *.google.com proxy all google.com sub-domains to use "proxy".
MAP test.com [::1]:77 "test.com" to use IPv6 loopback addresses. Port 77. is also enforced.
MAP * baz, EXCLUDE www.google.com remapped to "baz", except "www.google.com".

These maps apply to terminal network requests (TCP connections and host resolution in a direct connection, CONNECT proxy connections, and terminal host SOCKS SOCKS proxy connections).

--host-resolver-rules= `rules`

Similar --host-rules but rules suitable for host resolution.

--ignore-certificate-errors

Ignore certificate-related errors.

--ppapi-flash-path= `path`

Set the path path for the Pepper Flash path .

--ppapi-flash-version= `version`

Set the Pepper Flash plug-in version number.

--log-net-log= `path`

Enable blog events to be read to path .

--ssl-version-fallback-min= `version`

Set the most simplified SSL/TLS version number ("tls1", "tls1.1" or "tls1.2"), and TLS accepts fallback.

--cipher-suite-blacklist= `cipher_suites`

Specifies comma-separated SSL crypt suite list effect.

--disable-renderer-backgrounding

Prevent Chromium from lowering the priority of hidden rendering processes.

This flag is globally valid for all rendering processes, and if you only want to disable it in one window, you can use the hack method playing silent audio .

--enable-logging

Print Chromium information output to the console.

This switch will work if app.commandLine.appendSwitch is resolved before the ELECTRON_ENABLE_LOGGING environment variables to achieve the same effect.

--v= `log_level`

Set the default maximum active V-logging standard; The default is 0. Usually the V-logging standard value is positive.

This switch is only --enable-logging is on.

--vmodule= `pattern`

Giving each module the largest V-logging levels to override --v gives .E.g. my_module=2,foo*=3 my_module.* in the code of all source files my_module. foo*.*

Any mode that contains forward slash or backward will be tested to block the entire path name and is not only an E.g module. */foo/bar/*=2 level in all source file codes under foo/bar will be changed .

This switch is only


     --enable-logging

is on.
