Passing additional env variables to the portal

To provide additional environment variables to the portal, you need to implement the EnvVariablesService interface and provide it to the portal options.

EnvVariablesService Interface

The interface is defined as follows:

export interface EnvVariablesService {
    getEnv: (
        request: Request,
        response: Response,
    ) => Promise<Record<string, object>>;
}

The getEnv method is called by the application during environment variables retrieval (/rest/envconfig call) and receives the following parameters:

• request: the incoming request object
• response: the outgoing response object

Provide your implemented service to the portal options

import { Module } from '@nestjs/common';
import { PortalModule, PortalModuleOptions } from '@openmfp/portal-server-lib';

const portalOptions: PortalModuleOptions = {
    envVariablesProvider: EnvVariablesServiceImpl
};

@Module({
    imports: [PortalModule.create(portalOptions)],
})
export class AppModule {}
