I am receiving similar errors on my local machine. I raised this as a question on StackOverfow. The issue seems to be with compatiblity between the current version of Deno and the @firebase/app
module, not the @firebase/auth
module, and occurs when initializing the app with initializeApp
.
I dug through the firebase
module source code, and found the aliases of the objects mentioned in the errors:
Alias | Actual | Reference |
---|---|---|
Ke | #asNumber | firebase-js-sdk/packages/firestore/src/model/transform_operation.ts |
Ze | IndexedDbPersistence#attachVisibilityHandler | firebase-js-sdk/packages/firestore/src/local/indexeddb_persistence.ts |
Getting the same error. Additionally, can't connect Firestore in Deno script to a local emulator.
By the way, importing from https://www.gstatic.com/firebasejs/9.6.0/firebase-app.js
will work the firestore and realtime database.
// example
// @deno-types="https://cdn.esm.sh/v58/[email protected]/app/dist/app/index.d.ts"
import { deleteApp, FirebaseOptions, initializeApp } from "https://www.gstatic.com/firebasejs/9.6.0/firebase-app.js";
// @deno-types="https://cdn.esm.sh/v58/[email protected]/database/dist/database/index.d.ts"
import { getDatabase, ref, set } from "https://www.gstatic.com/firebasejs/9.6.0/firebase-database.js";
const app = initializeApp({...});
const db = getDatabase(app);
await set(ref(db), 1);

The solution from @ayame113 works for me, however when importing the Firestore library I can't use destructuring. E.g.
// does not work
import {
getFirestore
} from "https://www.gstatic.com/firebasejs/9.6.0/firebase-firestore.js";
// error: Property 'getFirestore' does not exist on type 'typeof import("https://cdn.esm.sh/v58/[email protected]/database/dist/database/index.d.ts")'.
// works
import * as fs from "https://www.gstatic.com/firebasejs/9.6.0/firebase-firestore.js";
fs.getFirestore()
I got it working using the gstatic URLs with the latest versions which required some API changes in the app - this gist is working for me https://gist.github.com/bgrins/e3f9ba9430da7b1c5a44241172779db0.
