Multiple MongoDB Connections

To have multiple MongoDB connections one needs to add a connectionName string to forRoot and forFeature.

forRoot usage

app.module.ts

import { Module } from "@nestjs/common";

import { TypegooseModule } from "nestjs-typegoose";

@Module({

imports: [

TypegooseModule.forRoot("mongodb://localhost:27017/otherdb", {

useNewUrlParser: true,

connectionName: "other-mongodb"

}),

CatsModule

]

})

export class ApplicationModule {}

cat.module.ts

@Module({

imports: [TypegooseModule.forFeature([Cat], "other-mongodb")],

controllers: [CatsController],

providers: [CatsService]

})

export class CatsModule {}

Here the CatsService will use the other-mongodb connection defined in the forRoot.

forRootAsync usage

Same cat.module.ts as above for the forFeature.

cat.module.ts

@Module({

imports: [TypegooseModule.forFeature([Cat], "other-mongodb")],

controllers: [CatsController],

providers: [CatsService]

})

export class CatsModule {}

And for forRootAsync add connectionName to the options as well.

@Module({

imports: [

TypegooseModule.forRootAsync({

connectionName: "other-mongodb",

imports: [ConfigModule],

useFactory: async (configService: ConfigService) => ({

uri: configService.getString("MONGODB_URI"),

// ...typegooseOptions (Note: config is spread with the uri)

}),

inject: [ConfigService]

})

]

})

export class CatsModule {}
