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.
Criteria | Value |
|---|---|
Current Release Branch | release-4.5.0 |
NPM Published version (Latest) | 4.5.1 |
NPM Package Name | @project-sunbird/client-services |
NPM Link | |
Works | Across All JavaScript Based Projects |
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

│ └── /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";
To install the package
npm i @project-sunbird/[email protected]
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
}
);
}
If the client for the library is a cordova project, use the 'HttpClientCordovaAdapter' adapter or use 'HttpClientBrowserAdapter'. 'HttpClientBrowserAdapter' is the default if not specified.
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);
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
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();
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>;
}
CsModule.instance.init({
...
services: {
frameworkServiceConfig: { // optional
apiPath: '<path>'
}
}
);
export interface CsFrameworkService {
getFramework(id: string, options?: GetFrameworkOptions, config?: CsFrameworkServiceConfig): Observable<Framework>;
}
CsModule.instance.init({
...
services: {
locationServiceConfig: { // optional
apiPath: '<path>'
}
}
);
export interface CsLocationService {
searchLocations(request?: SearchLocationRequests, config?: CsLocationServiceConfig): Observable<Location[]>;
}
CsModule.instance.init({
...
services: {
courseServiceConfig: { // optional
apiPath: '<path>'
}
}
);
export interface CsCourseService {
getUserEnrollmentList(request: GetUserEnrollmentListRequests, additionalParams?: { [key: string]: string }, config?: CsCourseServiceConfig): Observable<Course[]>;
}
