If you're trying out different data models, optimizing your security rules, or working to find the most cost-effective way to interact with the back-end, being able to work locally without deploying live services can be a great idea. A Cloud Firestore emulator is part of the Local Emulator Suite, which enables your app to interact with your emulated database content and config, as well as optionally your emulated project resources (functions, other databases, and security rules). Using the Cloud Firestore emulator involves just a few steps: <ol> <li>Adding a line of code to your app's test config to connect to the emulator.</li> <li>From the root of your local project directory, running <code translate="no" dir="ltr">firebase emulators:start</code>.</li> <li>Making calls from your app's prototype code using a Cloud Firestore platform SDK as usual.</li> </ol> A detailed <a href="/docs/emulator-suite/connect_and_prototype?database=Firestore">walkthrough involving Cloud Firestore and Cloud Functions</a> is available. You should also have a look at the <a href="/docs/emulator-suite">Local Emulator Suite introduction</a>. <h2 id="initialize" data-text="Initialize Cloud Firestore" tabindex="-1">Initialize Cloud Firestore</h2> Initialize an instance of Cloud Firestore: <div class="ds-selector-tabs" data-ds-scope="lang"> <section> <h3 translate="no" id="web_2" data-text="Web" tabindex="-1">Web</h3> <div></div><devsite-code><pre class="devsite-click-to-copy devsite-code-highlight" translate="no" dir="ltr" is-upgraded syntax="Python">import { initializeApp } from "firebase/app"; import { getFirestore } from "firebase/firestore"; // TODO: Replace the following with your app's Firebase project configuration // See: https://support.google.com/firebase/answer/7015592 const firebaseConfig = { <var translate="no">FIREBASE_CONFIGURATION</var> }; // Initialize Firebase const app = initializeApp(firebaseConfig); // Initialize Cloud Firestore and get a reference to the service const db = getFirestore(app); </pre></devsite-code> Replace <var translate="no">FIREBASE_CONFIGURATION</var> with your web app's <a href="https://support.google.com/firebase/answer/7015592"><code translate="no" dir="ltr">firebaseConfig</code></a>.
