Creating an app using the NEO® App SDK Starter Kit

If you are creating an app using the NEO® App SDK repo https://github.com/BconeLabs/neo-app-sdk.git then do the following

1. Register your app using NEO® Developer App (https://developer.<tenant>-neo.bcone.com)
2. Create a empty environment configuration with a name.
3. Update the environment.ts with the values configured in above steps

export const environment = {
    ...
    ...
    application_id: '', // Application id used in Step #1 
    config_fetch_env: '', // Environement name used in Step #2
    graphql_url: '' // https://graphql.<tenant>-neo.bcone.com
    ...
}

To override the default app configurations, login to NEO® Developer App and change the following values.

<i>client_id</i> - client id that has access to the cognito pool    
<i>pool_id</i> - cognito pool id that authenticates the user

Creating/Modifying existing angular application

[email protected] is compataible with Angular version 7.2.x . If in your project is using Angular version below 7.2.x please update Angular & typescript using step 1 and 2.

1. Update Angular core and Angular cli

   ng update @angular/[email protected] @angular/[email protected]

2. Update typescript version

   npm install --save-dev [email protected]

If you are creating or modifying an existing app that has not used this npm package follow the below mentioned steps.

1. Install neo-app-sdk npm package

   npm install --save @bcone/neo-app-sdk

   npm install --save [email protected]  [email protected]  [email protected]  [email protected] 

2. Update app.module.ts

   Import the following in app.module.ts

   import { InitConfigService } from '@bcone/neo-app-sdk';
   import { TokenInterceptor } from '@bcone/neo-app-sdk';
   import { MessageService } from '@bcone/neo-app-sdk';
   import { NeoAppsdkLoginModule } from '@bcone/neo-app-sdk';
   import { AuthGuard } from '@bcone/neo-app-sdk';
   import { NeoUtilService } from '@bcone/neo-app-sdk';

   Add the following code in @NgModule imports section

   imports: [
       ...
       ...
       NeoTableauModule,
       NeoAppsdkLoginModule.forRoot(appEnv)
   ]

   Inject following services in @NgModule Providers of app.module.ts

   providers: [
       ...
       ...
       AuthGuard,
       MessageService,
       InitConfigService,
       NeoUtilService,
       {
           provide: APP_INITIALIZER,
           useFactory: (config: InitConfigService) => () => config.load(),
           deps: [InitConfigService],
           multi: true
       },
       {
           provide: HTTP_INTERCEPTORS,
           useClass: TokenInterceptor,
           multi: true
       }
   ]

3. Create/Update login component

   Create login (do not change the name) component if it does not exist

   ng g c login
   

   Add login component as a parent

   const routes: Routes = [
       ...
       ...
       {
           path: 'login',
           component: LoginComponent,
       }
   ]

   In login.component.html replace the content with the following directive/component

   <ngx-neo-appsdk-login [enableCognito]="true" [enableSso]="true"></ngx-neo-appsdk-login>

   enableCognito (Boolean) - To enable/disable cognito login

   enableSso (Boolean) - To enable/disable SSO login

4. Privacy Policy acceptance

   To enable Privacy Policy acceptance use the following tag in app.component.html file

   <ngx-neo-app-privacy-policy [enablePrivacyPolicy]="true"></ngx-neo-app-privacy-policy>

   enablePrivacyPolicy (Boolean) - To enable/disable privacy policy acceptance

5. Customize default login screen (Optional)

   To customize Login Page UI use html injection. For Sidebar injection use loginSidebar attribute in div tag. For header injection use loginHeader attribute in div tag.

   <ngx-neo-appsdk-login>
       <div loginSidebar>
       // insert login sidebar HTML content here
       </div>
       <div loginHeader>
           // insert login header text here
       </div>
   </ngx-neo-appsdk-login>

6. Customize default header (Optional)

   To inject custom UI in header, use the following section

   <ngx-neo-app-header>
       <div headerLogo>
           <div class="d-inline">
           <span class="app-logo">
               <img src="<path-to-the-logo>">
           </span>
           </div>
       </div>
       <div navigationLink>
           <ul class="customNav">
           <li>...</li>
           <li>...</li>
           </ul>
       </div>
   </ngx-neo-app-header>

7. Implement checkFragmentUrl()

   Invoke checkFragmentUrl() if SSO Login is used to display or hide intermediate screen or navigation based on fragment

   
   ngOnInit() {
       ......
       ......
       if(this.neoUtilService.checkFragmentUrl()) {
               this.showSideBar = true; // Here We enable sidebar during SSO login
       } else {
           this.showSideBar = false; //Here We disable sidebar during SSO login
       }
   }
   

Tableau Widget

To use Tableau feature import NeoTableauModule in respective components module.ts file

import {  NeoTableauModule } from '@bcone/neo-app-sdk';

imports: [
    ...
    ...
    NeoTableauModule
]

In components html file add the following section

<div *ngIf="tableauConfig" >
<ngx-neo-tableau  [tableauConfig]="tableauConfig"></ngx-neo-tableau>
</div>

In components ts file define tableauConfig

const tableauConfig ={
    userName="",
    tenantName="",
    dashboardPath="",
    tableauProxyApi="",
    tableauServer=""

}

Customize redirection to the landing page

If an app wants to redirect logged in user to a different landing page based on custom logic (Based on role, user profile, etc.) use the following approach.

Define custom logic shown below

dynamicRouteFn(claim: any): string {
    // claim contain roles, userprofiles, etc.
    let redirectUrl = '' // Set default url if is not matched
    if(claim.roles && claim.roles.legth > 0) {
        claim.roles.foreach((role) => {
            if(role === 'Developer') {
                redirectUrl = 'developer-landing-url'
            }
            if(role === 'Data-scientist') {
                redirectUrl = 'data-scientist-landing-page';
            }
        });
    }
    return redirectUrl;
}

Inject defined callback function into ssoreturn() method & cognitosignin() of NeoUtilService Class. this.neoUtilService.ssoReturn(this.dynamicRouteFn); this.neoUtilService.cognitoSignIn(this.dynamicRouteFn);

How to use claim object in component or Html

Claims which are permissions on features can be configured in NEO® App Developer.

For configure please follow product handbook below given link https://docs.bristleconeneo.com/202003/neo_handbook/ProviderDeveloper.html

After configuration claim object is available in the below given format based on the role of the user

claims:{ 
      "page.page-name.view":true,
      "entity.entity-name.edit": true,
      "component.component-name.view": true,
   }

Claim object contains three part, first is compononent type like page/component/entity, second consists name of component and last part of claim object contains CRUD(Create, Read, Update & Delete) operation of component of HTML.

For example, the claim for page aboutUs and has view permission. The claim for that particular page would be

page.aboutUs.view = true;

Component conditioning based on claim object can be implemented as below

<app-aboutUs-component *ngIf="page.aboutUs.view"> </app-aboutUs-component>

TableauJS component

TableauJS component is useful to display Tableau Chart using tableau js api. It provide refresh, revert, extract option.

Use

index.html

........
........
 <script src="https://public.tableau.com/javascripts/api/tableau-2.min.js"></script>

Paste the above script in index.html

To use Tableau feature import NeoTableauModule in respective components module.ts file

import {  NeoTableauJSModule } from '@bcone/neo-app-sdk';

imports: [
    ...
    ...
    NeoTableauJSModule
]

In components ts file define tableauConfig

xyz.component.ts

import { NgOnint } from '@angular/common';
.......................
.......................

const declare tableau : any; 


export class XyzComponent implements OnInit {
    ................
    ................
    tableau = tableau;
    tableauConfig
    tabOption = {
        .....
        height: '500px',
        .....
    }

    constructor() {

    }

    ngOninit() {
        const tableauConfig ={
            userName="",
            tenantName="",
            dashboardPath="",
