Overview

The library is grouped into Modules and SubModules as shown below -
@project-sunbird/client-services
├── /core
│ └── /http-service
│ └── /utilities
│ └── /interceptors
├── /models
│ ├── /channel
│ ├── /content
│ ├── /course
│ ├── /device
│ ├── /faq
│ ├── /form
│ ├── /group
│ ├── /organisation
│ ├── /page
│ └── /user
└── /services
├── /content
│ └── /utilities
│ └── /content-group-generator
└── /group
The public facing API is prefixed with 'Cs' namespace, as in -
  • CsModule
  • CsConfig
  • CsGroupService
  • ...
For instance,
  • CsModule is part of the root module
  • CsContentsGroupGenerator is a utlility within content service
Their respective imports would be -
import {CsModule} from "@project-sunbird/client-services";
import {CsContentsGroupGenerator} from "@project-sunbird/client-services/services/content/utilities/content-group-generator";
​

Installation

To install the package
npm i @project-sunbird/[email protected]
The package requires the consumer to have [email protected] installed as the only peerDependency

Getting Started

To use the library CsModule, it needs to be initialised with basic configuration. CsModule is a singleton and it would be best to check if it has already been initialised before attempting to initialise -
if (!CsModule.instance.isInitialised) { // Singleton initialised or not
await CsModule.instance.init({
core: {
httpAdapter: 'HttpClientBrowserAdapter', // optional - HttpClientBrowserAdapter or HttpClientCordovaAdapter, default - HttpClientBrowserAdapter
global: {
channelId: 'some_channel_id', // required
producerId: 'some_producer_id', // required
deviceId: 'some_random_device_id' // required
},
api: {
host: 'https://staging.ntp.net.in', // default host
authentication: {
// userToken: string; // optional
// bearerToken: string; // optional
}
}
},
services: {
// groupServiceConfig: CsGroupServiceConfig // optional
}
);
}

Adapters

If the client for the library is a cordova project, use the 'HttpClientCordovaAdapter' adapter or use 'HttpClientBrowserAdapter'. 'HttpClientBrowserAdapter' is the default if not specified.

Update Configuration

The configuration can be dynamically reset after initialisation
const newConfig = {...CsModule.instance.config}; // copy existing config
​
newConfig.core.api.authentication = {
bearerToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXV.eyJpc3MiOiJzdGFnaW5nLmRpa3NoYS5hcHAtYTMzM2YzZjExZDM0YzlkNWYwZTE2MjUyYWMwZDVhYTZmMTBjYSIsImlhdCI6MTU4ODkxNDc1NX0.dEmjK6LStoenL_pRX1KwEtU4-opuUOUGI05ecex',
};
​
CsModule.instance.updateConfig(CsModule.instance.config);
​
// after login
​
newConfig.core.api.authentication = {
userToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXV.eyJpc3MiOiJzdGFnaW5nLmRpa3NoYS5hcHAtYTMzM2YzZjExZDM0YzlkNWYwZTE2MjUyYWMwZDVhYTZmMTBjYSIsImlhdCI6MTU4ODkxNDc1NX0.dEmjK6LStoenL_pRX1KwEtU4-opuUOUGI05ecex',
};
​
CsModule.instance.updateConfig(CsModule.instance.config);

Accessing a service

The CsModule being a singleton, every service within would also be a singleton, To access any service -
const httpService = CsModule.instance.httpService; // handles API calls, interceptors (tokens, logging)
const groupService = CsModule.instance.groupService; // internally uses httpService

Services

Every service by default will utilise the optional configuration declared during init() or updateConfig()
CsModule.instance.init({
...
services: {
groupServiceConfig: { // optional
apiPath: '/api/v1/group'
}
}
);
Additionally, methods of the service may have an optional argument that can override the global configuration explicitly just for that method call
const group = await groupService.getById(
group1.identifier,
{ apiPath: '/api/v2/group' } // optional
).toPromise();

CsGroupService

This service deals with user group management and has the following interface -
CsModule.instance.init({
...
services: {
groupServiceConfig: { // optional
apiPath: '/api/v1/group'
}
}
);
​
interface CsGroupService {
create(
name: string,
board: string,
medium: string | string[],
gradeLevel: string | string[],
subject: string | string[],
config?: CsGroupServiceConfig
): Observable<Group>;
​
deleteById(id: string, config?: CsGroupServiceConfig): Observable<void>;
​
getAll(config?: CsGroupServiceConfig): Observable<Group[]>;
​
getById(id: string, config?: CsGroupServiceConfig): Observable<Group>;
​
addMemberById(memberId: string, groupId: string, config?: CsGroupServiceConfig): Observable<Group>;
​
removeMemberById(memberId: string, groupId: string, config?: CsGroupServiceConfig): Observable<void>;
}

CsFrameworkService

CsModule.instance.init({
...
services: {
frameworkServiceConfig: { // optional
apiPath: '<path>'
}
}
);
​
export interface CsFrameworkService {
getFramework(id: string, options?: GetFrameworkOptions, config?: CsFrameworkServiceConfig): Observable<Framework>;
}

CsLocationService

CsModule.instance.init({
...
services: {
locationServiceConfig: { // optional
apiPath: '<path>'
}
}
);
​
export interface CsLocationService {
searchLocations(request?: SearchLocationRequests, config?: CsLocationServiceConfig): Observable<Location[]>;
}

CsLocationService

CsModule.instance.init({
...
services: {
courseServiceConfig: { // optional
apiPath: '<path>'
}
}
);
​
export interface CsCourseService {
getUserEnrollmentList(request: GetUserEnrollmentListRequests, additionalParams?: { [key: string]: string }, config?: CsCourseServiceConfig): Observable<Course[]>;
}
