How to use mongo-seeding - 4 common examples

require('dotenv-safe').config()
const { Seeder } = require('mongo-seeding')
const path = require('path')
const config = {
  database: process.env.MONGO_URI,
  inputPath: path.resolve(__dirname, './data'),

    console.log('Seed complete!')
    process.exit(0)
  } catch (err) {

}
