Nestjs - Typeorm custom connection name - connection

Question

I have a Nestjs db Module and it works perfectly
#Module({
imports: [
TypeOrmModule.forRootAsync({
useFactory: () => {
return {
name: 'default', // <=== here
type: "mysql",
...
};
},
}),
TypeOrmModule.forFeature(entities, 'default'), // <=== here
],
exports: [TypeOrmModule],
})
export class DBModule {}
if I change the connection name to anything else rather then 'default' say 'test' I get an error
#Module({
imports: [
TypeOrmModule.forRootAsync({
useFactory: () => {
return {
name: 'test', // <=== here
type: "mysql",
...
};
},
}),
TypeOrmModule.forFeature(entities, 'test'), // <=== here
],
exports: [TypeOrmModule],
})
export class DBModule {}
[Nest] 10746 - 05/15/2021, 5:55:34 PM [ExceptionHandler] Nest can't resolve dependencies of the test_UserEntityRepository (?). Please make sure that the argument testConnection at index [0] is available in the TypeOrmModule context.
Potential solutions:
- If testConnection is a provider, is it part of the current TypeOrmModule?
- If testConnection is exported from a separate #Module, is that module imported within TypeOrmModule?
#Module({
imports: [ /* the Module containing testConnection */ ]
})
The error seams to only show up if I use TypeOrmModule.forRootAsync
For TypeOrmModule.forRoot if works!
Is there any different way to indicate the connection name? I need to add another connection and can't do it because of this error. Really would like to use 'forRootAsync'

Answer 1

Pass the connection name as follows.
#Module({
imports: [
TypeOrmModule.forRootAsync({
name: 'test', // <=== here
useFactory: () => {
return {
type: "mysql",
...
};
},
}),
TypeOrmModule.forFeature(entities, 'test'), // <=== here
],
exports: [TypeOrmModule],
})
export class DBModule {}
