1. Mar 21, 2019  'Cloud Datastore User' is the appropriate Role for Service Accounts. I then saved my key as a JSON file for use in building JWTs for authenticating requests. I click Create key to save my Service Account Configuration as a JSON file. This is used in the next step to build out the JWT for authentication requests to the Firestore API.
2. Jun 20, 2019  Now Firebase comes up with a more advanced version of it as Cloud Firestore. I will show you step by steps how we can use Cloud Firestore in Flutter. Cloud Firestore is also a NoSQL Database like realtime database, but the difference is in the structure of data storage. Realtime database stores data in JSON tree.
3. Cloud Firestore is a NoSql Document database built for automatic scaling, high performance, real time, and ease of application development. Usersdata is the collection and document name will be obtained by auto key value. (Source Credit Google Cloud Platform). Select Cloud Firestore Database and create a project in test mode.
4. In this case, Cloud Firestore automatically generates the document identifier. Create an empty document with an automatically generated identifier, and assign data to.
5. Mar 04, 2020 Install Dependencies Enable the Cloud Firestore API. Install dependencies via Composer. Create a service account at the Service account section in the Cloud Console Download the json key file of the service account. Set GOOGLEAPPLICATIONCREDENTIALS environment variable pointing to that file.
6. In part 8 of the Firestore tutorial we replace our DocumentReferences’ set method for the CollectionReference’s add method to add more than one document into our Notebook collection. Instead of giving each document a name, Firestore will auto generate a random ID for them.

These samples show how to use the Google Cloud Firestore API to store and query data.

POST (collection) Document Id - randomly generated by firebase or by me USER (collection) Document Id - randomly generated by firebase userPost: String (this will be the document id in the post collection that I'm trying to get) firebase firebase-realtime-database google-cloud-firestore.

Setup

Prerequisites

1. Open the Firebase Console and create a new project. (You can't use both Cloud Firestore and Cloud Datastore in the same project, which might affect apps using App Engine. Try using Cloud Firestore with a different project if this is the case).

2. In the Database section, click Try Firestore Beta.

3. Click Enable.

Authentication

Authentication is typically done through Application Default Credentialswhich means you do not have to change the code to authenticate as long asyour environment has credentials. You have a few options for setting upauthentication:

1. When running locally, use the Google Cloud SDK

2. When running on App Engine or Compute Engine, credentials are alreadyset-up. However, you may need to configure your Compute Engine instancewith additional scopes.

3. You can create a Service Account key file. This file can be used toauthenticate to Google Cloud Platform services from any environment. To usethe file, set the GOOGLE_APPLICATION_CREDENTIALS environment variable tothe path to the key file, for example:

Install Dependencies

1. Enable the Cloud Firestore API.

2. Install dependencies via Composer.Run php composer.phar install (if composer is installed locally) or composer install(if composer is installed globally).

3. Create a service account at theService account section in the Cloud Console

4. Download the json key file of the service account.

5. Set GOOGLE_APPLICATION_CREDENTIALS environment variable pointing to that file.

Samples

To run the Cloud Firestore Samples:

The client library

This sample uses the Google Cloud Client Library for PHP.You can read the documentation for more details on API usage and use GitHubto browse the source and report issues.

Troubleshooting

If you get the following error, set the environment variable GCLOUD_PROJECT to your project ID:

If you have not set a timezone you may get an error from php. This can be resolved by:

Auto Generate Key Cloud Firestore Login

1. Finding where the php.ini is stored by running php -i grep 'Configuration File'
2. Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
3. Editing the php.ini file (or creating one if it doesn't exist)
4. Adding the timezone to the php.ini file e.g., adding the following line: date.timezone = 'America/Los_Angeles'
