Sure, I can help you with that as a senior backend developer. Here's the code we'll be writing:

``` 
// app.module.ts
import { Module } from '@nestjs/common';
import { UserModule } from './user/user.module';
import { AuthModule } from './auth/auth.module';
import { PermissionsModule } from './permissions/permissions.module';

@Module({
  modules: [UserModule, AuthModule, PermissionsModule]
})
export class AppModule {}

// user/user.module.ts
import { Module } from '@nestjs/common';
import { UserController } from './user.controller';
import { UserService } from './user.service';

@Module({
  controllers: [UserController],
  providers: [UserService],
  exports: [UserService]
})
export class UserModule {}

// auth/auth.module.ts
import { Module } from '@nestjs/common';
import { AuthController } from './auth.controller';
import { AuthService } from './auth.service';
import { PassportModule } from '@nestjs/passport';
import { LocalStrategy } from './local.strategy';

@Module({
  controllers: [AuthController],
  providers: [AuthService, LocalStrategy],
  exports: [AuthService],
  imports: [PassportModule.register({ defaultStrategy: 'local' })]
})
export class AuthModule {}

// permissions/permissions.module.ts
import { Module } from '@nestjs/common';
import { PermissionsController } from './permissions.controller';
import { PermissionsService } from './permissions.service';

@Module({
  controllers: [PermissionsController],
  providers: [PermissionsService],
  exports: [PermissionsService]
})
export class PermissionsModule {}

As a Senior Backend Developer using Nest.js and TypeORM, to implement professional access permissions guards based on user roles with a list of permissions, you can follow these steps:

1. Set up Nest.js project:
   - Install Nest CLI globally: `npm install -g @nestjs/cli`
   - Create a new Nest.js project: `nest new my-app`
   - Install required dependencies: `npm install typeorm @nestjs/typeorm`

2. Create a database schema for users and permissions:
   - Create a `User` entity with fields like `id`, `username`, `password`, and `role` (e.g., `admin`, `editor`, `viewer`).
   - Create a `Permission` entity with a `name` field (e.g., `create-post`, `update-post`, `delete-post`, etc.).

3. Set up TypeORM:
   - Configure TypeORM in your `ormconfig.json` file.
   - In your `app.module.ts`, import `TypeOrmModule` and add it to the `imports` array.

4. Create a `User` service and repository:
   - Create a `user.service.ts` file and import the necessary dependencies (`Injectable`, `User`, `UserRepository`, etc.).
   - Implement methods to retrieve, create, update, and delete users.

5. Create a `Permission` service and repository:
   - Repeat the same steps as for the `User` service and repository.

6. Implement access control guards:
   - Create a `RoleGuard` decorator using Nest's `@Injectable()` and `@Guard()` annotations.
   - In the guard, retrieve the user's role from the request context (e.g., using a middleware or injecting a `User` service).
   - Check if the user's role matches the required role for the protected route.
   - If the user has the correct role, allow access, otherwise, return a `ForbiddenException`.

7. Create a `PermissionGuard` decorator to restrict access based on permissions:
   - Similar to the `RoleGuard`, create a `PermissionGuard` decorator using Nest's `@Injectable()` and `@Guard()` annotations.
   - In the guard, retrieve the required permissions for the protected route from the route metadata (e.g., using a `@UseGuards()` decorator).
   - Check if the user's permissions array includes all the required permissions.
   - If the user has the necessary permissions, allow access, otherwise, return a `ForbiddenException`.

8. Merge the guards and permissions in a single `index.js` file:
   - Import the necessary modules, services, and decorators.
   - Export the `RoleGuard` and `PermissionGuard` decorators.

9. Apply the guards to your routes:
   - In your `app.controller.ts`, use the `@UseGuards()` decorator to apply the guards to the appropriate routes.

Remember, this is a high-level overview, and the implementation details may vary based on your specific requirements and project structure. Good luck with your project!
