const express = require('express');
const multer = require('multer');
const { createConnection, Entity, PrimaryGeneratedColumn, Column } = require('typeorm');

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

@Entity()
class File {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  filename: string;

  @Column()
  path: string;
}

createConnection().then(async connection => {
  const fileRepository = connection.getRepository(File);

  app.post('/upload', upload.single('file'), async (req, res) => {
    const file = new File();
    file.filename = req.file.originalname;
    file.path = req.file.path;

    await fileRepository.save(file);

    res.send('File uploaded successfully');
  });

  app.listen(3000, () => {
    console.log('Server is running on port 3000');
  });
}).catch(error => console.log(error));
