Sunbird Client Services
In order to facilitate Adopters to connect with Sunbird System. Typescript based library to connect with APIs. It can facilitate the adopters with readily available data models.
Current Release Branch

Works
Across All JavaScript Based Projects
Overview
The library is grouped into Modules and SubModules as shown below -
@project-sunbird/client-services
βββ /core
β βββ /http-service
β βββ /utilities
β βββ /interceptors
βββ /models
β βββ /channel
β βββ /content
β βββ /course
β βββ /device
β βββ /faq
β βββ /form
β βββ /group
β βββ /organisation
β βββ /page
β βββ /user
βββ /services
βββ /content
β βββ /utilities
β βββ /content-group-generator
βββ /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[]>;
}
