NestJS Autoloader

Simplify your NestJS modules by automatically loading providers and controllers.

Installation

npm i nestjs-autoloader

Nest Compatibility

NestJS Autoloader works with Nest v8.2.4 and up.

Usage

import { AutoloadModule } from 'nestjs-autoloader';

@AutoloadModule(__dirname)
export class YourModule {}

The first argument of the AutoloadModule decorator should always be __dirname, this is the directory it will read and load files from. The second argument is optional, and is the same as for a normal Module. Here you can specify imports, additional providers, etc. For example:

import { AutoloadModule } from 'nestjs-autoloader';

@AutoloadModule(__dirname, {
  imports: [OtherModule],
  providers: [NonAutoloadedProvider]
})
export class YourModule {}

Example

Before:

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

@Module({
  controllers: [AuthController],
  providers: [AuthService, AdminService],
  imports: [TypeOrmModule.forFeature([Admin])],
  exports: [AuthService],
})
export class AuthModule {}

After:

import { AutoloadModule } from 'nestjs-autoloader';

@AutoloadModule(__dirname, {
  imports: [TypeOrmModule.forFeature([Admin])],
  exports: [AuthService],
})
export class AuthModule {}

Nested Module Directories

The autoloader is designed to work with nested module directories. For example:

parent/
├── parent.module.ts
├── parent.service.ts
└── sub/
    ├── sub.module.ts
    └── sub.service.ts

This will load the parent.service.ts for the parent module, but not the sub.service.ts. The autoloader recognises nested modules by looking at *.module.ts files. If a directory contains a file with that name, it will exclude this directory from autoloading for the containing module.
