Config

Ionic Config provides a way to change the properties of components globally across an app. It can set the app mode, tab button layout, animations, and more.

Global Config

To override the default Ionic configurations for your app, provide your own custom config to IonicModule.forRoot(...). The available config keys can be found in the IonicConfig interface.

For example, to disable ripple effects and default the mode to Material Design:

app.module.ts
import { IonicModule } from '@ionic/angular';

@NgModule({
...
imports: [
IonicModule.forRoot({
rippleEffect: false,
mode: 'md'
})
],
...
})

Per-Component Config

Ionic Config is not reactive. Updating the config's value after the component has rendered will result in the previous value. It is recommended to use a component's properties instead of updating the config, when you require reactive values.

Not recommended

import { IonicModule } from '@ionic/angular';

@NgModule({
...
imports: [
IonicModule.forRoot({
// Not recommended when your app requires reactive values
backButtonText: 'Go Back'
})
],
...
})

Recommended

<ion-back-button [text]="backButtonText"></ion-back-button>
@Component(...)
class MyComponent {
backButtonText = this.config.get('backButtonText');

constructor(private config: Config) { }

localeChanged(locale: string) {
if (locale === 'es_ES') {
this.backButtonText = 'Devolver';
}
}

}

Per-Platform Config

Ionic Config can also be set on a per-platform basis. For example, this allows you to disable animations if the app is being run in a browser on a potentially slower device. Developers can take advantage of the Platform utilities to accomplish this.

Since the config is set at runtime, you will not have access to the Platform Dependency Injection. Instead, you can use the underlying functions that the provider uses directly.

In the following example, we are disabling all animations in our Ionic app only if the app is running in a mobile web browser. The isPlatform() call returns true or false based upon the platform that is passed in. See the Platform Documentation for a list of possible values.

import { isPlatform, IonicModule } from '@ionic/angular';

@NgModule({
...
imports: [
IonicModule.forRoot({
animated: !isPlatform('mobileweb')
})
],
...
})

Per-platform config with fallback for unmatched platforms:

import { isPlatform, IonicModule } from '@ionic/angular';

const getConfig = () => {
if (isPlatform('hybrid')) {
return {
backButtonText: 'Previous',
tabButtonLayout: 'label-hide'
}
}

return {
menuIcon: 'ellipsis-vertical'
}
}
@NgModule({
...
imports: [
IonicModule.forRoot(getConfig())
],
...
})

Per-platform config overrides:

import { isPlatform, IonicModule } from '@ionic/angular';

const getConfig = () => {
let config = {
animated: false
};

if (isPlatform('iphone')) {
config = {
...config,
backButtonText: 'Previous'
}
}

return config;
}
@NgModule({
...
imports: [
IonicModule.forRoot(getConfig())
],
...
})

Methods

get

DescriptionReturns a config value as an any. Returns null if the config is not defined.
Signatureget(key: string, fallback?: any) => any

Examples

import { Config } from '@ionic/angular';

@Component(...)
class AppComponent {
constructor(config: Config) {
const mode = config.get('mode');
}
}

getBoolean

DescriptionReturns a config value as a boolean. Returns false if the config is not defined.
SignaturegetBoolean(key: string, fallback?: boolean) => boolean

Examples

import { Config } from '@ionic/angular';

@Component(...)
class AppComponent {
constructor(config: Config) {
const swipeBackEnabled = config.getBoolean('swipeBackEnabled');
}
}

getNumber

DescriptionReturns a config value as a number. Returns 0 if the config is not defined.
SignaturegetNumber(key: string, fallback?: number) => number

Examples

import { Config } from '@ionic/angular';

@Component(...)
class AppComponent {
constructor(config: Config) {
const keyboardHeight = config.getNumber('keyboardHeight');
}
}
