Integrate the Firebase Admin SDK API with the MongoDB API

import admin from "firebase-admin"
export default defineComponent({
  props: {
    firebase_admin_sdk: {
      type: "app",
      app: "firebase_admin_sdk",
    },

  async run({ steps, $ }) {
    // Enter values for the following parameters below this code step,
    // These get passed to the initializeApp method below.
    const { 
      projectId, 
      clientEmail, 
      privateKey,
      region = "firebaseio.com",
    } = this.firebase_admin_sdk.$auth

    // Before passing the privateKey to the initializeApp constructor,
    // we have to replace newline characters with literal newlines
    const formattedPrivateKey = privateKey.replace(/\\n/g, "\n")

    // See https://firebase.google.com/docs/reference/admin/node/admin.credential.html#cert
    if (!admin.apps.length) {
      admin.initializeApp({
        credential: admin.credential.cert({
          projectId,
          clientEmail,

        }),
        databaseURL: `https://${projectId}-default-rtdb.${region}/`,
      })
    }
  },
