@tsed/multipartfiles

A package of Ts.ED framework. See website: https://romakita.github.io/ts-express-decorators/

Installation

Before using the @MultipartFile() you must install multer module on your project:

npm install --save multer @types/multer @tsed/multipartfiles

Then import @tsed/multipartfiles in your ServerLoader:

import {ServerLoader, ServerSettings} from "@tsed/common";
import "@tsed/ajv"; // import ajv ts.ed module
import Path = require("path");
const rootDir = Path.resolve(__dirname);

@ServerSettings({
   rootDir: __dirname,
   uploadDir: `${rootDir}/custom-dir`,                                    
   multer: {
      // see multer options
   }
})
export class Server extends ServerLoader {

}

By default the directory used is ${projetRoot}/uploads. You can configure another directory on your ServerLoader settings.

Options

dest (string): The destination directory for the uploaded files.
storage (`StoreEngine): The storage engine to use for uploaded files.
limits (Object): An object specifying the size limits of the following optional properties. This object is passed to busboy directly, and the details of properties can be found on https://github.com/mscdex/busboy#busboy-methods.
- fieldNameSize (number): Max field name size (Default: 100 bytes).
- fieldSize (number): Max field value size (Default: 1MB).
- fields (number): Max number of non- file fields (Default: Infinity).
- fileSize (number): For multipart forms, the max file size (in bytes)(Default: Infinity).
- files (number): For multipart forms, the max number of file fields (Default: Infinity).
- parts (number): For multipart forms, the max number of parts (fields + files)(Default: Infinity).
- headerPairs (number): For multipart forms, the max number of header key => value pairs to parse Default: 2000(same as node's http).
- preservePath (boolean): Keep the full path of files instead of just the base name (Default: false).

Example

Ts.ED use multer to handler file uploads. Single file can be injected like this:

import {Controller, Post} from "@tsed/common";
import {Multer} from "@types/multer";

type MulterFile = Express.Multer.File;

@Controller('/')
class MyCtrl {
    
  @Post('/file')
  private uploadFile(@MultipartFile() file: MulterFile) {

  }
     
  @Post('/file')
  private uploadFile(@MultipartFile({dest: "/other-dir"}) file: MulterFile) {
         
  }
}

For multiple files, just add Array type annotation like this:

import {Controller, Post} from "@tsed/common";
import {Multer} from "multer";
import {MultipartFile} from "@tsed/multipartfile";

type MulterFile = Express.Multer.File;

@Controller('/')
class MyCtrl {
  @Post('/files')
  private uploadFile(@MultipartFile() files: MulterFile[]) {

  }
}
