Class: CommandLine
Class: CommandLine
Manipulate the command line arguments for your app that Chromium reads
Process: Main
This class is not exported from the 'electron'
module. Es ist nur als Rückgabewert anderer Methoden in der Electron-API verfügbar.
Das folgende Beispiel zeigt, wie man überprüfen kann, ob die --disable-gpu
Flagge gesetzt ist.
const { app } = require('electron')
app.commandLine.hasSwitch('disable-gpu')
For more information on what kinds of flags and switches you can use, check out the Command Line Switches document.
Beispiel Methoden
commandLine.appendSwitch(switch[, value])
switch
string - A command-line switch, without the leading--
.value
string (optional) - A value for the given switch.
Append a switch (with optional value
) to Chromium's command line.
Note: This will not affect process.argv
. The intended usage of this function is to control Chromium's behavior.
const { app } = require('electron')
app.commandLine.appendSwitch('remote-debugging-port', '8315')
commandLine.appendArgument(value)
value
string - The argument to append to the command line.
Append an argument to Chromium's command line. The argument will be quoted correctly. Switches will precede arguments regardless of appending order.
If you're appending an argument like --switch=value
, consider using appendSwitch('switch', 'value')
instead.
const { app } = require('electron')
app.commandLine.appendArgument('--enable-experimental-web-platform-features')
Note: This will not affect process.argv
. The intended usage of this function is to control Chromium's behavior.
commandLine.hasSwitch(switch)
switch
string - A command-line switch.
Returns boolean
- Whether the command-line switch is present.
const { app } = require('electron')
app.commandLine.appendSwitch('remote-debugging-port', '8315')
const hasPort = app.commandLine.hasSwitch('remote-debugging-port')
console.log(hasPort) // true
commandLine.getSwitchValue(switch)
switch
string - A command-line switch.
Returns string
- The command-line switch value.
This function is meant to obtain Chromium command line switches. It is not meant to be used for application-specific command line arguments. For the latter, please use process.argv
.
const { app } = require('electron')
app.commandLine.appendSwitch('remote-debugging-port', '8315')
const portValue = app.commandLine.getSwitchValue('remote-debugging-port')
console.log(portValue) // '8315'
Note: When the switch is not present or has no value, it returns empty string.
commandLine.removeSwitch(switch)
switch
string - A command-line switch.
Entfernt den angegebenen Schalter von der Kommandozeile von Chromium.
const { app } = require('electron')
app.commandLine.appendSwitch('remote-debugging-port', '8315')
console.log(app.commandLine.hasSwitch('remote-debugging-port')) // true
app.commandLine.removeSwitch('remote-debugging-port')
console.log(app.commandLine.hasSwitch('remote-debugging-port')) // false
Note: This will not affect process.argv
. The intended usage of this function is to control Chromium's behavior.
