管理者として、ファイルをアップロードする為のサンプルコードはこちら

const { initializeApp, cert } = require("firebase-admin/app");

const { getStorage } = require("firebase-admin/storage");

const KEY_FILENAME_PATH = "<KEY_FILENAME_PATH>";
const BUCKET_NAME = "<BUCKET_NAME>";
const LOCAL_FILE = "./storage/test.csv";

const serviceAccount = require(KEY_FILENAME_PATH);

process.env["FIREBASE_STORAGE_EMULATOR_HOST"] = "localhost:9199";

initializeApp({
  credential: cert(serviceAccount),
  storageBucket: BUCKET_NAME,
});

const bucket = getStorage().bucket();

bucket.upload(LOCAL_FILE, {}, async function (err, callback) {
  if (err) {
    console.log(err);
  } else {
    console.log(`uploaded!!!`);
  }
});

クライアントとして、ファイルをアップロードする為のサンプルコードはこちら

const { initializeApp } = require("firebase/app");
const {
  getStorage,
  connectStorageEmulator,
  ref,
  uploadBytes,
} = require("firebase/storage");
const { readFileSync } = require("fs");

const API_KEY_STR = "<API_KEY_STR>";

const LOCAL_FILE = "./storage/test.csv";

const firebaseConfig = {
  apiKey: API_KEY_STR,
  authDomain: PROJECT_ID + ".firebaseapp.com",
  databaseURL: "https://asia-northeast1.firebaseio.com/",
  projectId: PROJECT_ID,
  storageBucket: PROJECT_ID + ".appspot.com",
};

const app = initializeApp(firebaseConfig);
const storage = getStorage(app);
connectStorageEmulator(storage, "localhost", 9199);

const storageRef = ref(storage, "test.csv");

const metadata = {
  contentType: "text/csv",
};

const localFile = readFileSync(LOCAL_FILE);
uploadBytes(storageRef, localFile, metadata);

このようなエラーが出ると思うが

その時はstorage.rulesを更新するか認証用の機能を実装しよう

[StorageError [FirebaseError]: Firebase Storage: User does not have permission to access 'test.csv'. (storage/unauthorized)] {
  code: 'storage/unauthorized',
  customData: { serverResponse: '' },
  _baseMessage: "Firebase Storage: User does not have permission to access 'test.csv'. (storage/unauthorized)"
}

認証関係のエラーですね

Emulatorで使ってみたいだけなら、このよう書き換えても良いだろう

ただし、本番へデプロイしないよう注意すること

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if true;
    }
  }
}

デプロイすると危険ですね
