# Supported Chrome command line switches
|
|
|
|
> Command line switches supported by Electron.
|
|
|
|
You can use [app.commandLine.appendSwitch][append-switch] to append them in
|
|
your app's main script before the [ready][ready] event of the [app][app] module
|
|
is emitted:
|
|
|
|
```javascript
|
|
const {app} = require('electron');
|
|
app.commandLine.appendSwitch('remote-debugging-port', '8315');
|
|
app.commandLine.appendSwitch('host-rules', 'MAP * 127.0.0.1');
|
|
|
|
app.on('ready', () => {
|
|
// Your code here
|
|
});
|
|
```
|
|
|
|
## --ignore-connections-limit=`domains`
|
|
|
|
Ignore the connections limit for `domains` list separated by `,`.
|
|
|
|
## --disable-http-cache
|
|
|
|
Disables the disk cache for HTTP requests.
|
|
|
|
## --remote-debugging-port=`port`
|
|
|
|
Enables remote debugging over HTTP on the specified `port`.
|
|
|
|
## --js-flags=`flags`
|
|
|
|
Specifies the flags passed to JS engine. It has to be passed when starting
|
|
Electron if you want to enable the `flags` in the main process.
|
|
|
|
```bash
|
|
$ electron --js-flags="--harmony_proxies --harmony_collections" your-app
|
|
```
|
|
|
|
## --proxy-server=`address:port`
|
|
|
|
Use a specified proxy server, which overrides the system setting. This switch
|
|
only affects requests with HTTP protocol, including HTTPS and WebSocket
|
|
requests. It is also noteworthy that not all proxy servers support HTTPS and
|
|
WebSocket requests.
|
|
|
|
## --proxy-bypass-list=`hosts`
|
|
|
|
Instructs Electron to bypass the proxy server for the given semi-colon-separated
|
|
list of hosts. This flag has an effect only if used in tandem with
|
|
`--proxy-server`.
|
|
|
|
For example:
|
|
|
|
```javascript
|
|
app.commandLine.appendSwitch('proxy-bypass-list', '<local>;*.google.com;*foo.com;1.2.3.4:5678')
|
|
```
|
|
|
|
Will use the proxy server for all hosts except for local addresses (`localhost`,
|
|
`127.0.0.1` etc.), `google.com` subdomains, hosts that contain the suffix
|
|
`foo.com` and anything at `1.2.3.4:5678`.
|
|
|
|
## --proxy-pac-url=`url`
|
|
|
|
Uses the PAC script at the specified `url`.
|
|
|
|
## --no-proxy-server
|
|
|
|
Don't use a proxy server and always make direct connections. Overrides any other
|
|
proxy server flags that are passed.
|
|
|
|
## --host-rules=`rules`
|
|
|
|
A 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
|
|
|
|
Ignores certificate related errors.
|
|
|
|
## --ppapi-flash-path=`path`
|
|
|
|
Sets the `path` of the pepper flash plugin.
|
|
|
|
## --ppapi-flash-version=`version`
|
|
|
|
Sets the `version` of the pepper flash plugin.
|
|
|
|
## --log-net-log=`path`
|
|
|
|
Enables net log events to be saved and writes them to `path`.
|
|
|
|
## --ssl-version-fallback-min=`version`
|
|
|
|
Sets the minimum SSL/TLS version (`tls1`, `tls1.1` or `tls1.2`) that TLS
|
|
fallback will accept.
|
|
|
|
## --cipher-suite-blacklist=`cipher_suites`
|
|
|
|
Specifies comma-separated list of SSL cipher suites to disable.
|
|
|
|
## --disable-renderer-backgrounding
|
|
|
|
Prevents Chromium from lowering the priority of invisible pages' renderer
|
|
processes.
|
|
|
|
This flag is global to all renderer processes, if you only want to disable
|
|
throttling in one window, you can take the hack of
|
|
[playing silent audio][play-silent-audio].
|
|
|
|
## --enable-logging
|
|
|
|
Prints Chromium's logging into console.
|
|
|
|
This switch can not be used in `app.commandLine.appendSwitch` since it is parsed
|
|
earlier than user's app is loaded, but you can set the `ELECTRON_ENABLE_LOGGING`
|
|
environment variable to achieve the same effect.
|
|
|
|
## --v=`log_level`
|
|
|
|
Gives the default maximal active V-logging level; 0 is the default. Normally
|
|
positive values are used for V-logging levels.
|
|
|
|
This switch only works when `--enable-logging` is also passed.
|
|
|
|
## --vmodule=`pattern`
|
|
|
|
Gives the per-module maximal V-logging levels to override the value given by
|
|
`--v`. E.g. `my_module=2,foo*=3` would change the logging level for all code in
|
|
source files `my_module.*` and `foo*.*`.
|
|
|
|
Any pattern containing a forward or backward slash will be tested against the
|
|
whole pathname and not just the module. E.g. `*/foo/bar/*=2` would change the
|
|
logging level for all code in the source files under a `foo/bar` directory.
|
|
|
|
This switch only works when `--enable-logging` is also passed.
