How To Add Document With Custom Id To Firestore

Firestore is a powerful tool for managing data in your applications, and being able to add documents with custom IDs can be a handy feature to have in your coding toolbox. In this article, we'll walk through the steps to do just that.

To add a document with a custom ID to Firestore, you first need to have your Firebase project set up and be familiar with the basics of using Firestore in your application. If you haven't set up Firestore yet, you can find detailed instructions on the Firebase documentation website.

Once your project is set up, the first thing you'll need to do is get a reference to the Firestore database. You can do this by calling the `collection` method on your Firestore instance and passing in the name of the collection where you want to add the document. For example, if you have a collection called "users," you can get a reference to it like this:

const usersRef = firebase.firestore().collection('users');

Next, you'll need to create a document reference with the custom ID you want to use. You can do this by calling the `doc` method on your collection reference and passing in the custom ID as an argument. For instance, if you want to add a document with the ID "john_doe" to the "users" collection, you can do it like this:

const customIdDocRef = usersRef.doc('john_doe');

After that, you can simply call the `set` method on the document reference to add the document to Firestore with the custom ID and any data you want to include. For example, if you want to store a user's name and email address, you can do it like this:

customIdDocRef.set({
    name: 'John Doe',
    email: '[email protected]'
});

And that's it! You've successfully added a document with a custom ID to Firestore. This can be useful in various scenarios, such as when you want to use a specific identifier for your documents that differs from Firestore's auto-generated IDs.

Remember that when you add a document with a custom ID, Firestore will automatically create the document if it doesn't exist or update it if it does. So, make sure to handle this behavior according to your application's requirements.

In conclusion, adding a document with a custom ID to Firestore is a straightforward process that can come in handy in many situations. By following the steps outlined in this article, you can efficiently manage your data in Firestore and tailor it to your application's needs. Happy coding!
