In Node.js web server development,

you can use formidable to implement file upload.

qiao-z-upload

You can refer to the official documentation for formidable usage.

Here is a packaged npm module for convenience: https://code.insistime.com/#/qiao-z-upload

qiao-z-upload is the upload plugin for qiao-z,

which depends on the qiao-z web server framework.

qiao-z

qiao-z is a minimalist Node.js web server framework.

See: https://qiao-z.vincentqiao.com/#/

In qiao-z, you can easily implement file upload.

1. Pass in the qiao-z-upload plugin during initialization

// options
const options = {
  // upload, handles file upload requests, returns file info to req.body
  upload: require('qiao-z-upload'),
};

// app
const app = qz(options);

2. Get the uploaded file information from req.body.files

/**
 * upload controller
 */
module.exports = (app) => {
  // upload
  app.post('/upload', async (req, res) => {
    console.log(req.body.files);
  });
};
