Question

我在云功能上使用firebase云功能和javascript。而且，我想从javascript切换到打字稿。

但是我不能在typescript上使用firebase-admin，因为以下命令失败。

command: npm install @types/firebase-admin --save-dev
error:  '@types/firebase-admin' is not in the npm registry.

根据此发行说明，它看起来firebase管理员支持打字稿。有人可以告诉我们如何在云功能上使用带有firebase-admin的typescript吗？

Answer 1

您无需安装@types模块，因为firebase-admin附带了TypeScript支持。您只需安装firebase-admin即可将其与TypeScript一起使用。

Answer 2

使用ES6模块导入时似乎提供了类型：

tsconfig.json

{
    "compilerOptions": {
        "resolveJsonModule": true,               // json imports
        "esModuleInterop": true,                 // import common modules as ES6 Modules
        "allowSyntheticDefaultImports": true,    // support typesystem compatibility
    }
}

index.ts

import firebase from 'firebase-admin';
import serviceAccount from './service-account.json';

const params = {               //clone json object into new object to make typescript happy
    type: serviceAccount.type,
    projectId: serviceAccount.project_id,
    privateKeyId: serviceAccount.private_key_id,
    privateKey: serviceAccount.private_key,
    clientEmail: serviceAccount.client_email,
    clientId: serviceAccount.client_id,
    authUri: serviceAccount.auth_uri,
    tokenUri: serviceAccount.token_uri,
    authProviderX509CertUrl: serviceAccount.auth_provider_x509_cert_url,
    clientC509CertUrl: serviceAccount.client_x509_cert_url
}

firebase.initializeApp({
    credential: firebase.credential.cert(params),
})

我知道我迟到了，但我找到了另一种方法来做到这一点，使用彼得给出的答案：

tsconfig.json

{
    "compilerOptions": {
        "resolveJsonModule": true,               // json imports
        "esModuleInterop": true,                 // import common modules as ES6 Modules
        "allowSyntheticDefaultImports": true,    // support typesystem compatibility
    }
}

index.ts

import firebase from 'firebase-admin';
import serviceAccount from './service-account.json';

firebase.initializeApp({
    credential: firebase.credential.cert(serviceAccount as any), //Cast as any instead of clone the JSON.
})

Answer 4

另一种选择可能是这种方式。

import * as admin from 'firebase-admin';
import * as serviceAccount from './service-account.json';

const firebaseAdmin = admin.initializeApp({
   credential: admin.credential.cert(serviceAccount as admin.ServiceAccount)
});

Answer 5

对于那些仍在苦苦挣扎的人，在安装 firebase-admin 后重新加载 VSCode 对我有用。
