Installation
Install ngx-loading via NPM, using the command below.
NPM
npm install --save ngx-loading
NOTE: Version 3 of this package (latest) requires Angular 6 as a dependency. If you are using Angular 4 / 5, please install version 2.0.1:
npm install --save ngx-loading@2.0.1
Getting started
Import the NgxLoadingModule
in your root application module:
;;;;
You must create a boolean variable (e.g. loading
below) that is accessible from the component which will contain ngx-loading. This boolean is used as an input into ngx-loading, and will determine when the loading spinner is visible.
;
Next, add the ngx-loading component selector to your application component's template. Set the [show]
input variable of ngx-loading to point to your boolean, which will determine when ngx-loading is visible. Optionally set the [config]
input variable of ngx-loading to setup custom configuration options. If the [config]
input variable is not set, the globally configured configuration will be used, if set. If no config options are set, the ngx-loading default config options will be used. See Config options for further information.
You can also optionally define a [template]
input variable, which can be used to inject your own custom templates into the component.
NOTE: ngx-loading will fill the entirety of its parent component. If you wish for ngx-loading to only fill a specific element within your component, ensure that ngx-loading is a child element of that element, and that the containing element has its position
attribute set to relative
.

Input parameters
Input | Required | Details |
---|---|---|
show | Required | A boolean, which will determine when ngx-loading is visible. |

Config options
Option | Required | Default | Details |
---|---|---|---|
animationType | Optional | ngxLoadingAnimationTypes.threeBounce | The animation to be used within ngx-loading. Use the ngxLoadingAnimationTypes constant to select valid options. |
backdropBorderRadius | Optional | 0 | The border-radius to be applied to the ngx-loading backdrop, e.g. '14px'. |
backdropBackgroundColour | Optional | rgba(0, 0, 0, 0.3) | The background-color to be applied to the ngx-loading backdrop, e.g. 'rgba(255, 255, 255, 0.2)'. |
fullScreenBackdrop | Optional | false | Set to true to make the backdrop full screen, with the loading animation centered in the middle of the screen. |
primaryColour | Optional | #ffffff | The primary colour, which will be applied to the ngx-loading animation. |
secondaryColour | Optional | #ffffff | The secondary colour, which will be applied to the ngx-loading animation (where appropriate). |
tertiaryColour | Optional | #ffffff | The tertiary colour, which will be applied to the ngx-loading animation (where appropriate). |
Config options can be set globally (using the .forRoot() module import statement
), as well as being passed into each ngx-loading instance, if required. Config options that are passed into an ngx-loading element will override any custom global config options that have been set. A combination of the two can be used together if appropriate. If no config is set, the default ngx-loading config options will be used. Please see below for an example custom configuration setup, using both global and local configurations.
