Maybe we need writing a depth limiter manually (see microsoft/TypeScript#45711).

Sorry, this is my problem, I used DataSourceOptions as ConfigType incorrectly, sorry for wasting your precious time.

import { registerAs } from '@nestjs/config'

import { DataSource, DataSourceOptions } from 'typeorm'
+ import { MysqlConnectionCredentialsOptions } from 'typeorm/driver/mysql/MysqlConnectionCredentialsOptions'
import { env, envBoolean, envNumber } from '~/global/env'
// eslint-disable-next-line import/order
import dotenv from 'dotenv'

dotenv.config({ path: `.env.${process.env.NODE_ENV}` })

const dataSourceOptions: DataSourceOptions = {
  type: 'mysql',
  host: env('DB_HOST', '127.0.0.1'),
  port: envNumber('DB_PORT', 3306),
  username: env('DB_USERNAME'),
  password: env('DB_PASSWORD'),
  database: env('DB_DATABASE'),
  synchronize: envBoolean('DB_SYNCHRONIZE', false),
  entities: ['dist/modules/**/*.entity{.ts,.js}'],
  migrations: ['dist/migrations/*{.ts,.js}'],
  subscribers: ['dist/modules/**/*.subscriber{.ts,.js}'],
}
export const dbRegToken = 'database'

export const DatabaseConfig = registerAs(
  dbRegToken,
  (): DataSourceOptions => dataSourceOptions,
)

- export type IDatabaseConfig = ConfigType<typeof DatabaseConfig>
+ export type IDatabaseConfig = Pick<MysqlConnectionCredentialsOptions, 'host' | 'port' | 'username' | 'password' | 'database'>

const dataSource = new DataSource(dataSourceOptions)

export default dataSource
