//script 
//node dev-data/data/import-dev-data.js --import
//node dev-data/data/import-dev-data.js --delete
//dev-data/data/import-dev-data.js
const fs = require('fs');
const dotenv = require('dotenv');
const mongoose = require('mongoose');
const Tour = require('./../../models/tourModel');

dotenv.config({ path: './config.env' });

const DB = process.env.DATABASE.replace(
  '<PASSWORD>',
  process.env.DATABASE_PASSWORD
);
// console.log(process.env.DATABASE);
mongoose
  .connect(DB, {
    useNewUrlParser: true,
  })
  .then(() => console.log('DB connection successful!'));

// READ JSON FILE
const tours = JSON.parse(
  fs.readFileSync(`${__dirname}/tours-simple.json`, 'utf-8')
);

// IMPORT DATA INTO DB
const importData = async () => {
  try {
    await Tour.create(tours);
    console.log('Data successfully loaded!');
  } catch (err) {
    console.log(err);
  }
  process.exit();
};

// DELETE ALL DATA FROM DB
const deleteData = async () => {
  try {
    await Tour.deleteMany();
    console.log('Data successfully deleted!');
  } catch (err) {
    console.log(err);
  }
  process.exit();
};

//calling function from terminal by checking 3rd element of process.argv
if (process.argv[2] === '--import') {
  importData();
} else if (process.argv[2] === '--delete') {
  deleteData();
}
