AddPdfToMongoDB

YusifHasanov

This creates a new Mongoose GridFS model, stores a file in that model and then writes the file to a given path.

const mongoose = require('mongoose');
const Grid = require('mongoose-gridfs');

const conn = mongoose.createConnection(uri, { useNewUrlParser: true });
const gridfs = new Grid(conn.db, mongoose.mongo);

const storage = gridfs.model;

const pdf = new storage({
  filename: 'file.pdf',
  contentType: 'application/pdf',
});
pdf.write(fs.createReadStream('path/to/file.pdf'), (error) => {
  if (error) {
    console.log(error);
  } else {
    pdf.save((error) => {
      if (error) {
        console.log(error);
      } else {
        console.log('file saved');
      }
    });
  }
});
