A circular dependency might also be caused when using "barrel files"/index.ts files to group imports. Barrel files should be omitted when it comes to module/provider classes. For example, barrel files should not be used when importing files within the same directory as the barrel file, i.e. cats/cats.controller should not import cats to import the cats/cats.service file. For more details please also see this github issue.

If you encountered an error like this:
Nest can't resolve dependencies of the <provider> (?). Please make sure that the argument <unknown_token> at index [<index>] is available in the <module> context.
Potential solutions:
- If <unknown_token> is a provider, is it part of the current <module>?
- If <unknown_token> is exported from a separate @Module, is that module imported within <module>?
@Module({
imports: [ /* the Module containing <unknown_token> */ ]
})
Please make sure that the RedisModule is added directly to the imports array of @Module() decorator of "Root Module"(if isGlobal is true) or "Feature Module"(if isGlobal is false).
Examples of code:
// redis-config.service.ts
import { Injectable } from '@nestjs/common';
import { RedisModuleOptions, RedisOptionsFactory } from '@liaoliaots/nestjs-redis';
@Injectable()
export class RedisConfigService implements RedisOptionsFactory {
createRedisOptions(): RedisModuleOptions {
return {
readyLog: true,
config: {
host: 'localhost',
port: 6379,
password: 'authpassword'
}
};
}
}// app.module.ts
import { Module } from '@nestjs/common';
import { RedisModule } from '@liaoliaots/nestjs-redis';
import { RedisConfigService } from './redis-config.service';
@Module({
imports: [
RedisModule.forRootAsync({
useClass: RedisConfigService
})
]
})
export class AppModule {}// my-redis.module.ts
import { Module } from '@nestjs/common';
import { RedisModule } from '@liaoliaots/nestjs-redis';
import { RedisConfigService } from './redis-config.service';
@Module({
imports: [
RedisModule.forRootAsync({
useClass: RedisConfigService
})
]
})
export class MyRedisModule {}// app.module.ts
import { Module } from '@nestjs/common';
import { MyRedisModule } from './my-redis.module';
@Module({
imports: [MyRedisModule]
})
export class AppModule {}- Compatible with NestJS ^9
