Type Of Object Received During File Upload Using @uploadfile

In the REST API below, what is the type of file object that is received. @Post('/:folderId/documents/:fileName') @UseInterceptors(FileInterceptor('file')) @ApiConsumes('multipart/

Solution 1:

You can import the type from the package. '@types/multer' and then qualify the file as:

@UploadedFile() file: Express.Multer.File,

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/multer/index.d.ts#L103

Solution 2:

You can save the file by specifying a destination path in the MulterOptions:

// files will be saved in the /uploads folder@UseInterceptors(FileInterceptor('file', {dest: 'uploads'}))

---

If you want more control over how your file is saved, you can create a multer diskStorage configuration object instead:

import { diskStorage } from'multer';

exportconst myStorage = diskStorage({
  // Specify where to save the filedestination: (req, file, cb) => {
    cb(null, 'uploads');
  },
  // Specify the file namefilename: (req, file, cb) => {
    cb(null, Date.now() + '-' + file.originalname);
  },
});

And then pass it to the storage property in your controller.

@UseInterceptors(FileInterceptor('file', {storage: myStorage}))

For more configuration options, see the multer docs.

Solution 3:

try this...

@Post(':userid/avatar')
    @UseInterceptors(FileInterceptor('file',
      {
        storage: diskStorage({
          destination: './avatars', 
          filename: (req, file, cb) => {
          const randomName = Array(32).fill(null).map(() => (Math.round(Math.random() * 16)).toString(16)).join('')
          return cb(null, `${randomName}${extname(file.originalname)}`)
        }
        })
      }
    )
    )
    uploadAvatar(@Param('userid') userId, @UploadedFile() file) {
      this.userService.setAvatar(Number(userId), `${this.SERVER_URL}${file.path}`);
    }
