Installation

npm install nestjs-dispatch-module --save

Usage

DispatchModule.dispatchFromEnv can be used to lazy load modules based on the value of the environment variable.

import {DispatchModule} from 'nestjs-dispatch-module';

// Dispatch module inclusion based on an environment variable value, and optionally a fallback
@Module({
    imports: [DispatchModule.dispatchFromEnv(
        'MY_ENV_VAR',
        {
            production: import('./production').then(m => m.ProductionModule),
            staging: import('./staging').then(m => m.StagingModule),
        },
        {
            fallbackModule: () => import('./noop').then(m => m.NoopModule)
        }
    )]
})
export class AppModule {}

// Or if you prefer to implement your own dispatching logic
@Module({
    imports: [DispatchModule.dispatch({
        dispatch: (env: NodeJS.ProcessEnv) =>
            env['MY_VAR'] === 'production'
                ? import('./production').then(m => m.ProductionModule)
                : import('./noop').then(m => m.NoopModule)
    })]
})
export class AppModule {}
