Package Exports

@rosen-group/ngx-onboarding

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@rosen-group/ngx-onboarding) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ngx-onboarding

An onboarding library for Angular applications.

Onboarding example image

Overview

The Onboarding library gives you the possibility to add a tutorial directly into your angular application. After that users learn easily how to use your application and the learning curve is not so high.

You can specify an onboarding element on every html element you want.

Features

Definition of several steps on each view.
Highlighting of every step.
Configurable on which position (top, bottom, left or right) the information text should be displayed.
Multiple language support
If onboarding is enabled, buttons are visible to switch to the next step or turn off onboarding
If a user has seen the onboarding of a view, it will be stored per default to the local storage of the browser.
Possibility to reset and turn on again the onboarding.

Installation

The library is published as a scoped NPM package in the NPMJS Rosen-Group account

npm install --save @rosen-group/ngx-onboarding

Peer Dependencies

For detailed information how to use Angular material please have a look at the Angular material getting started page and follow the installations instructions.

Usage

Add the rosen-onboarding-component anywhere to your main component, e.g. app.component

<rosen-onboarding></rosen-onboarding>

Add the material icons reference to the index.html

<link href="//fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

The onboarding contains a button component which provides a context menu for resetting and turning on again the onboarding feature. Place this button into your application where you want.

<rosen-onboarding-button title="ONBOARDING"></rosen-onboarding-button>

Add the OnboardingModule, the OnboardingService and it's dependencies to your module, e.g.

    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        HttpClientModule,
        MatIconModule,
        MatButtonModule,
        OnboardingModule
    ],
    providers: [OnboardingService],

Add some styles, e.g. to your app.component.css ()

@import "~@angular/material/prebuilt-themes/indigo-pink.css";

And don't forget to bundle it to your output, e.g. in your angular.json

"styles": [
 "src/styles.css",
 "node_modules/@angular/material/prebuilt-themes/indigo-pink.css"
]

The messages will be configured in json files.

Place the json file(s) where you are able to load them on application runtime.
