@webundsoehne/nest-fastify-file-upload v2.2.0

Port of Nest's file upload and MulterModule for FastifyAdapter!

Compatibile with NestJS 7-10 and Fastify 3-4.

Steps:

Install to your project:

npm i @webundsoehne/nest-fastify-file-upload

IMPORTANT: Register contentParser in your root application after creation:

import { NestFactory } from '@nestjs/core'
import { FastifyAdapter, NestFastifyApplication } from '@nestjs/platform-fastify'
import { DocumentBuilder, SwaggerModule } from '@nestjs/swagger'
import { contentParser } from 'fastify-multer'

import { AppModule } from './app.module'

async function bootstrap (): Promise<void> {
  const app = await NestFactory.create<NestFastifyApplication>(AppModule, new FastifyAdapter())

  await app.register(contentParser)

  await app.listen(3000)
}

bootstrap()

Use it like the official NestJS package for Express in your controllers:

@Post('upload')
@UseInterceptors(FileInterceptor('file'))
@ApiFileBody('file')
@ApiConsumes('multipart/form-data')
uploadFile (@UploadedFile('file') file: MulterFile): void {
    console.log(file)
}

...

The package will export the missing Express.Multer.* types as Multer*.

@ApiFileBody Decorator

Useful controller decorator that adds file upload functionality in Swagger.

You can specify the file key as parameter, default key is file.

MulterModule

Register the MulterModule e.g. to directly upload to a specified directory.

import { Module } from '@nestjs/common'

import { AppController } from './app.controller'
import {MulterModule} from "../multer.module";

@Module({
  controllers: [AppController],
  imports: [
      MulterModule.register({dest: './uploads'})
  ]
})
export class AppModule { }
