尝试将 csv 文件数据导入 Firestore

Question

I am using the code below to upload data to Firestore but am getting the error message below:

SyntaxError: Cannot use import statement outside a module

on this line of code:

"import promises from 'fs';"

import { promises } from 'fs';
const { readFile } = promises;
import { promisify } from 'util';
const parse = promisify(import('csv-parse'));
import { Firestore } from '@google-cloud/firestore';

if (process.argv.length < 3) {
  console.error('Please include a path to a csv file');
  process.exit(1);
}

const db = new Firestore();

function writeToFirestore(records) {
  const batchCommits = [];
  let batch = db.batch();
  records.forEach((record, i) => {
    var docRef = db.collection('firebasetest').doc(record.acctid);
    batch.set(docRef, record);
    if ((i + 1) % 500 === 0) {
      console.log(`Writing record ${i + 1}`);
      batchCommits.push(batch.commit());
      batch = db.batch();
    }
  });
  batchCommits.push(batch.commit());
  return Promise.all(batchCommits);
}

async function importCsv(csvFileName) {
  const fileContents = await readFile(csvFileName, 'utf8');
  const records = await parse(fileContents, { columns: true });
  try {
    await writeToFirestore(records);
  }
  catch (e) {
    console.error(e);
    process.exit(1);
  }
  console.log(`Wrote ${records.length} records`);
}

importCsv(process.argv[2]).catch(e => console.error(e));

1. Download and install Firefoo .

2. sign in with Google. Right-click your project in the left sidebar and choose Import Collections.

3. Click on the Data File field and select your JSON or CSV file.

4. That's it. Click the Import button.

Your CSV rows are imported into Firestore and a progress popup opens.
