## [Customizable content types](https://strapi.io/features/custom-fields)

One of the critical features of Strapi is its ability to create customizable content types. The format of the data that Strapi handles is defined by content types, which can be customized to match the particular requirements of various projects and applications.

Strapi enables developers to build bespoke content kinds using a visual interface instead of scripting. They can establish validation criteria to guarantee that data is entered properly, define fields for each content type, and declare the data type for each field.

## [User management](https://docs.strapi.io/dev-docs/quick-start)

Strapi is an open-source headless (CMS)content management system that allows developers to create and manage API-driven content for various applications. User management is an essential feature in Strapi that enables administrators to manage users and control their access to the CMS.

With user management in Strapi, administrators can create, edit, and delete user accounts and assign roles and permissions to those accounts. Roles and permissions are defined in Strapi's Role-Based Access Control (RBAC) system, which allows administrators to create custom roles and specify the access level for each role. This ensures that users only have access to the content and functionality they need to do their job.

Some of the features available in Strapi's user management system include:

1. **User creation, modification, and deletion**: Administrators can create new user accounts, edit existing ones, and delete them when necessary.
2. **Role-based access control**: Strapi's RBAC system allows administrators to create custom roles and specify the access level for each role.

User management is a crucial feature in Strapi that allows administrators to control user access to the CMS and ensure the security of the content and data stored within it.

## [API-based](https://strapi.io/features/customizable-api)

A flexible and extensible framework for building API-driven apps, Strapi is an open-source headless content management system. One of the main advantages of Strapi is its API-based functionalities.

With a straightforward and user-friendly interface, Strapi makes it simple to construct RESTful APIs. Using the Strapi dashboard or the Strapi SDK, you can define your API endpoints, data models, and relationships. Additionally, you may set up your API to safeguard your data using multiple authentication techniques like JWT or OAuth.

Strapi offers out-of-the-box support for GraphQL APIs in addition to RESTful APIs. With GraphQL, a popular replacement for REST, you may query your data more effectively by just asking for the particular information you require.

## [Plugins and integrations](https://strapi.io/plugin-resources)

Strapi supports plugins and integrations as key features. These plugins and integrations enable developers to extend Strapi's functionality and integrate it with other services quickly.

[Plugins](https://github.com/strapi/strapi-plugin-seo) in Strapi are reusable packages of code that can be installed and configured to add specific features to Strapi's core functionality. For example, there are plugins for adding search functionality, image optimization, and user [authentication](https://strapi.io/blog/a-beginners-guide-to-authentication-and-authorization-in-strapi) to your Strapi application. Developers can create their plugins to share with the community or use plugins created by other developers.

Integrations, on the other hand, allow Strapi to work seamlessly with other services and tools. For example, there are integrations for deploying Strapi on various hosting platforms, integrating with email marketing services, and using Strapi with front-end frameworks like [React](https://strapi.io/integrations/react-cms) and [Vue](https://strapi.io/integrations/vuejs-cms). These integrations can be configured easily through Strapi's admin panel, saving developers time and effort.

Plugins and integrations in Strapi offer a flexible and customizable solution for developers who want to create robustly, tailored CMS solutions for their applications.

## [Cloud](https://strapi.io/cloud)

Strapi Cloud is designed to simplify the process of hosting and managing Strapi projects, making it easy for developers to focus on building and deploying their applications.

# Differences between Strapi and Firebase?

Strapi and Firebase are backend platforms that can be used to build web and mobile applications. Still, they have some differences in features, architecture, and target audiences.

Here are some of the key [differences](https://forum.strapi.io/t/difference-between-strapi-and-firebase/408) between Strapi and Firebase:

## Architecture

Strapi is an open-source, headless CMS (content management system) that provides a RESTful API for accessing and managing content. At the same time, Firebase is a cloud-based platform that offers a suite of services for building and managing mobile and web applications.

## Performance

Strapi and Firebase can both be quick and effective in terms of performance, but there are certain distinctions to take into account.

Strapi's adaptability and capacity to modify the backend to satisfy particular application requirements is one of its benefits. Lowering needless overhead and enhancing the effectiveness of database searches, can aid in speed optimization. However, the hosting environment and database can have a significant impact on Strapi's performance.

Contrarily, Firebase is a fully managed platform that handles a variety of performance-related concerns, including scaling and database optimization. In addition, Firebase offers a real-time database that can be tuned for low-latency data synchronization, which is useful for some applications.

Strapi and Firebase can both be quick and effective in general, but the performance can vary depending on a variety of things, including the particular use case, hosting environment, and database being used. Developers should carefully assess the needs of their applications and select the platform that best satisfies those needs.

## GraphQL

Different strategies for integrating GraphQL into their respective platforms are provided by [Strapi](https://docs.strapi.io/dev-docs/plugins/graphql#customization) and Firebase.

A flexible and adaptable backend solution is offered by Strapi, a headless CMS. It gives you complete control over the GraphQL implementation and the ability to link it with other technologies by enabling you to create your own GraphQL API by specifying your data models and schemas.

On the other hand, Google's [Firebase](https://firebaseopensource.com/projects/sejr/firegraph/) is a complete backend-as-a-service (BaaS) platform. It has capabilities like a real-time database, hosting, authentication, and others. Although Firebase's Cloud Firestore database does support GraphQL, the implementation is more closely connected with Firebase's ecosystem and services, offering a more simplified but less flexible approach compared to Strapi.

In conclusion, Firebase offers a managed, integrated GraphQL implementation within its larger BaaS platform, whereas Strapi offers a self-hosted, configurable GraphQL backend solution. Your particular requirements, preferences, and the degree of control you need over your GraphQL implementation will determine which option you should use.

## Vendor lock-in

*By making it impossible for consumers to transition to a rival without incurring significant expenses or problems, some technology vendors utilize a strategy known as vendor lock-in, also known as proprietary lock-in or customer lock-in, to keep their customers dependent on them for products and services.*

Open-source headless CMS called Strapi allows developers flexibility and control over the information and content of their applications. By allowing you to self-host the CMS and store your data in a database of your choosing, it lessens vendor lock-in.

On the other hand, Google's Firebase platform offers a variety of services for creating online and mobile applications. Firebase links you to Google's infrastructure, leading to a higher level of vendor lock-in, although it provides practical capabilities like real-time databases, authentication, and hosting.

In conclusion, Firebase relies on Google's infrastructure, leading to higher vendor lock-in, whereas Strapi allows you to choose your infrastructure and database, offering more freedom and independence.

## Backend customizability

There are various levels of backend customization available with [Strapi](https://docs.strapi.io/dev-docs/backend-customization) and [Firebase](https://firebase.google.com/docs/build).

An open-source headless CMS with a scalable backend architecture is called [Strapi](https://docs.strapi.io/dev-docs/backend-customization). By using their favorite programming language, it enables developers to establish their own data models, design unique APIs, and implement business logic. Large-scale modification and management of the backend infrastructure are made possible by this flexibility.

The backend-as-a-service platform [Firebase,](https://firebase.google.com/docs/build) on the other hand, provides a selection of pre-built backend services. In comparison to Strapi, Firebase's customization choices are more constrained even though it offers a variety of capabilities like authentication, real-time databases, cloud storage, and hosting. Although they do have some influence over the Firebase services themselves, developers have less control over the underlying infrastructure.

As an open-source CMS that enables developers to define their data models and implement custom logic, Strapi offers higher backend customizability in comparison to Firebase, which offers a practical and feature-rich backend platform but with fewer customization choices.

## Pricing

Strapi is a free and open-source headless CMS that enables the creation and administration of content APIs. You have complete control over the hosting environment and infrastructure costs because it is [self-hosted](https://strapi.io/pricing-self-hosted) and free to use. The usage of third-party hosting providers or the need for additional features from the Strapi ecosystem, such as plugins and themes, may, however, result in extra [charges](https://strapi.io/pricing-cloud).

Firebase, on the other hand, is a Backend-as-a-Service (BaaS) platform provided by Google. It offers various services, including a real-time database, authentication, hosting, and more. [Firebase](https://firebase.google.com/pricing) follows a pricing model based on usage, where you pay for specific resources consumed, such as storage, bandwidth, and API requests. While Firebase has a free tier with limited resources, costs can increase as your usage and requirements grow, particularly for higher traffic and storage needs.

In summary, Strapi provides a free and self-hosted solution, but additional costs may arise depending on your hosting choices and optional add-ons. Firebase offers a range of services with a usage-based pricing model, providing a free tier but potentially increasing costs as your application's needs scale.

# Implementing Firebase Auth into Strapi

Here are the steps on how to implement Firebase Auth into Strapi:

## Step 1

**Create a Firebase project and enable the Authentication service.**
Create a Firebase project in the Firebase console ([https://console.firebase.google.com](https://console.firebase.google.com/)) and click the "Create Project" button. Once your project is created, enable the Authentication service. Enable the Firebase Authentication service and configure the authentication methods you want to use (e.g., email/password, Google, Facebook).

## Step 2

**Install Firebase SDK**
In your Strapi project directory, install the Firebase SDK by running the following command:

    npm install firebase

## Step 3

**Download the Firebase Admin SDK and initialize it in your Strapi application.**
A JavaScript framework called the Firebase Admin SDK enables you to use code to communicate with Firebase services. The SDK is available for download from the Firebase website: https://firebase.google.com/docs/admin/setup.
To initialize the Firebase Admin SDK in your Strapi application, you need to create a file called `bootstrap.js` at the root of your Strapi project. In this file, you need to import the Firebase Admin SDK and initialize it with your Firebase project's credentials.

Below is an example of hope to initialize the Firebase Admin SDK in Strapi:

import firebase from "firebase/app";
import "firebase/auth";

firebase.initializeApp({
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  projectId: "YOUR_PROJECT_ID",
});

## Step 4

**Create a new Strapi user model and add the** `**firebaseId**` ``**field.**

Strapi uses a user model to store user information. To integrate Firebase Auth into Strapi, you need to create a new user model and add the `firebaseId`field. The `FirebaseId`field is a unique identifier that is assigned to each user when they sign in with Firebase Auth.

To create a new strapi user model with the `firebseId`field look at the code block below:

const user = {
  id: { type: "integer", primaryKey: true },
  email: { type: "string", unique: true },
  password: { type: "string" },
  firebaseId: { type: "string" },
};

module.exports = user;

## Step 5

**To validate the Firebase ID token, update the Strapi authentication middleware.**
Strapi uses middleware to authenticate users. To verify the Firebase ID token, you need to update the Strapi authentication middleware.

The Strapi authentication middleware is located in the `src/middleware/authentication.js`file. In this file, you need to add the following code to verify the Firebase ID token:

const firebase = require("firebase/auth");

module.exports = async (req, res, next) => {
  const firebaseIdToken = req.header("Authorization").split(" ")[1];
  const firebaseUser = await firebase.auth().verifyIdToken(firebaseIdToken);

  if (firebaseUser) {
    req.user = firebaseUser;
    next();
  } else {
    res.status(401).send("Unauthorized");
  }
};

## Step 6

**Update the Strapi login and registration pages to use Firebase Auth.**
Strapi provides default login and registration pages. To use Firebase Auth for these pages, you need to update the `src/pages/login.js` and `src/pages/register.js` files.
In these files, you need to import the Firebase Admin SDK and use it to sign in and register users with Firebase Auth.

The Strapi login page can be updated to use Firebase Auth by following this example:

import firebase from "firebase/auth";
    
module.exports = async (req, res) => {
  const email = req.body.email;
  const password = req.body.password;
    
  try {
  const firebaseUser = await firebase.auth().signInWithEmailAndPassword(email, password);
    
        res.status(200).send({
  success: true,
  user: firebase         

Following the steps correctly you will be able to implement your Firebase auth properly.
