Need help storing file to mongodb about node-typescript-mongodb

@hamzahalvanaa Hello. Did you try using this npm package https://www.npmjs.com/package/multer ?
Can you attach to the comment with an example of a request what you try to send? And please note, I did not find a file in your repository where you try to require multer library.

Hi, @ChechaValerii. Before, I am new to express and MongoDB. Using your template and find tutorials on how to storing a file to the database. Here is the example of how I storing file:

src/routes/index.ts

    const FOLDER_PATH = 'uploads';
    const upload = multer({ dest: `${FOLDER_PATH}`, fileFilter: UtilsProvider.imageFilter });
    app.use('/v1/uploads', upload.single('image'), UploadRouter);

src/components/Upload/index.ts

const DB_NAME = 'my_server';
const COLLECTION_NAME = 'uploadmodel';
const UPLOAD_PATH = 'uploads';
const db = new Loki(`${UPLOAD_PATH}/${DB_NAME}`, { persistenceMethod: 'fs' });

export async function findAll(req: Request, res: Response, next: NextFunction): Promise<void> {
    try {
        // const uploads: IUploadModel[] = await UploadService.findAll();
        const col = await UtilsProvider.loadCollection(COLLECTION_NAME, db);

        res.send(col.data);
        // res.status(200).json(uploads);
    } catch (error) {
        next(new HttpError(error.message.status, error.message));
    }
}

Could you show me the correct ways how to modeling and service file upload based on your template? Thank you.

Hello, sure I already create upload controller and test

components/Upload

import { HttpError } from '../../config/error';
import { NextFunction, Request, Response } from 'express';

/**
 * @export
 * @param {Request} req
 * @param {Response} res
 * @param {NextFunction} next
 * @returns {Promise < void >}
 */
export async function upload(req: Request, res: Response, next: NextFunction): Promise<void> {
    try {
        console.log(req.file); // all file info here
    } catch (error) {
        next(new HttpError(error.message.status, error.message));
    }
}

components/interface.ts

import { IUploadModel } from './model';

/**
 * @export
 * @interface IUploadService
 */
export interface IUploadService {

    /**
     * @returns {Promise<IUploadModel[]>}
     * @memberof IUploadService
     */
    upload(): Promise<IUploadModel[]>;
}

routes/index.ts

/**
  * @description
  *  Forwards any requests to the /v1/uploads URI to our UploadRouter
  *  Also, check if user authenticated
  * @constructs
  */
 app.use('/v1/uploads', UploadRouter);

routes/UploadRouter.ts

import { Router } from 'express';
import * as multer from 'multer';
import { UploadComponent } from '../components';

const router: Router = Router();

const upload: any = multer({ dest: 'uploads/' });

router.post('/upload', upload.single('avatar'), UploadComponent.upload);

export default router;

Please note, need add multer to a specific route, no need add parent.
And request must be with method POST and multipart/form-data
