在本地 Firebase 中，如何为当前环境设置 projectId？

Question

我正在尝试将一些测试数据写入本地版本的 Firebase。我在我的 .env.local（和 .env.development 文件）中定义了这些变量......

REACT_APP_MB_ACCESS_TOKEN="accesstoken"
ALGOLIA_APP_ID="appid"
ALGOLIA_API_KEY="apikey"
NODE_ENV="development"
FIREBASE_EMULATOR_HOST_VAR=localhost:9000
FIRESTORE_EMULATOR_HOST=localhost:8080
GCLOUD_PROJECT=mutualaid-123f6

我有以下设置（通过 npm run dev:upload）将虚拟数据上传到我的本地 Firebase ...

const admin = require("firebase-admin");

const data = require("./data.json");
let serviceAccount = process.env.FIREBASE_SECRET;
...

  require("dotenv").config();
  admin.initializeApp();
  db = admin.firestore();
...

async function upload(data, path) {
  console.log("starting ...");
  return await db
    .doc(path.join("/"))
    .set(data)
    .then(() => console.log(`Document ${path.join("/")} uploaded.`))
    .catch((e) => {
      console.error(`Could not write document ${path.join("/")}.`);
      console.log(e);
    });

adly 上面的结果是

...
Could not write document organizations/1/missions/aaf3c03c33ecf79e3d7ffddf401c01f0.
Error: Unable to detect a Project Id in the current environment.

或我的 data.json 文件中的所有数据（示例如下）。我还需要配置什么才能将此数据导入本地 Firebase？

{
  "organizations": {
    "1": {
      "missions": {
        "aaf3c03c33ecf79e3d7ffddf401c01f0": {
          "status": "started",
          "missionDetails": {
            "dummy": "This is only here because upload modules did not understand that we want this to be a field",
            "needs": [
              {
                "name": "Fruits & Veggies Medley",
                "quantity": 1
              }
            ]
          },
          "uid": "aaf3c03c33ecf79e3d7ffddf401c01f0",
          "deliveryConfirmationImage": "",
          "feedbackNotes": "",
          "groupUid": "Daly City 2020/03/05",
          "organizationUid": "1",
          "volunteerDisplayName": "Michael Williams",
          "deliveryWindow": {
            "timeWindowType": "as soon as possible",
            "startTime": "06/03/2020, 10:40:57"
          },

您尚未将配置对象传递给admin.initializeApp

由于您使用 dotenv 加载 env 文件，因此您可以创建一个包含 env 详细信息的配置对象，例如

const config = {
    type: "service_account",
    project_id: "xxx",
    credential: 'your credentials'
};

require("dotenv").config();
  admin.initializeApp({config});
  db = admin.firestore();

如果您没有将任何配置传递给initializeApp，那么您需要将其定义为FIREBASE_CONFIG env对象。

根据文档：

SDK也可以无参数初始化。在这种情况下，SDK 使用 Google 应用程序默认凭据并从FIREBASE_CONFIG环境变量中读取选项。如果变量的内容 FIREBASE_CONFIG以 { 开头，它将被解析为 JSON 对象。否则，SDK 假定该字符串是包含选项的 JSON 文件的名称。
