Are you looking to set up your first ever Angular 5 application? Getting such a project up and running is a lot easier than you think. Angular version 5 is quite new in the industry with amazing features and this version was rolled just a few months ago. Ahead of Time compiler, optimization with boosted speed and smaller bundles, and lighter and faster Http Client module are among the notable updates with the new version. Setting up an Angular 5 project has become the dream of many programming enthusiasts now. Adding the other technological advancements of the time, Bootstrap 4 and Firebase to the project can really make a difference in the final outcome.

Here you can see an overview of how to set up an Angular 5 Project with Bootstrap 4 and Firebase.

Set up Angular 5 Project

First let us see how to set up an Angular 5 project without much hassles:

  • The very first step is to setup an Angular project which is performed using Angular CLI. See that the installation of command line interface is done in case Angular CLI is not available in your system.
  • Now you can use the ‘ng’ command to commence a new Angular project. An application that works already will be created then. A single command generates components, services, routes and pipes.
  • The command line parameter ‘new’ has to be used and the new project’s name should be specified.
  • The development web server can be launched by executing the command ‘ng serve’ in the project folder.
  • Following this, the server will get started and you can now access the application. You can see a ‘welcome to app’ screen with some support links to help you with the journey.

Set up Firebase Project

Once you set up the Angular 5 project, you can move to the phase of setting up the Firebase project.

  • In the Firebase back-end, you are supposed to create a new Firebase project. After that the related project settings need to be transferred inside the Angular application.
  • Followed by that, the Angular project and Firebase libraries need to be linked to the project
  • Now you can visit the Firebase website in order to set up a new Firebase project
  • There you can easily set up a new account and use your Google credentials to sign in.
  • Once you have logged in, the link ‘Go To Console’ has to be clicked for getting the Firebase back-end.
  • In this place, the ‘Add project’ has to be clicked to link a new Firebase project or simply choose from your existing projects.
  • Now you can see the project console. There the link ‘Add Firebase to your web app’ can be clicked.
  • Now you will see the JavaScript code that guides you to the initialization of the Firebase project for the particular website.
  • However, for making this Firebase configuration a part of your Angular project, only a section of that code snippet is required. The key-value pairs within the config object has to be copied at first and those pairs has to be inserted within the file.

How to Add Bootstrap 4?

Finally, you can add the Bootstrap 4 to the already set up Angular 5 project. See the steps:

  • Use the NPM command for the installation of Bootstrap 4 into the project folder
  • Include the Bootstrap CSS file also in the project folder in order to access Bootstrap CSS classes for the project components
  • Use the Bootstrap Starter Template to include a Bootstrap user interface in the project application.
  • A starter template website gets opened in another browser window when you click on Starter template.
  • While opening the source code view of the browser, the starter template’s HTML markup code can be accessed.
  • The necessary code parts can be copied and then paste into your project application.
  • Use the Angular CLI again for including a new component to the project as you need to add the starter template’s navigation bar now.
  • Use Bootstrap 4 Angular directives in order to give Angular framework the complete control for updating DOM elements.

This is just a rough idea for building an Angular 5 project from scratch and adding Bootstrap 4 and Firebase to it. However, for a comprehensive project that has an unparalleled performance, you have to bring in advance features and customize it to your actual requirements. A dedicated effort from an enthusiast with a sound knowledge about the technical whereabouts is needed to set up a final project that is error free and that meets the specific requirements.

In fact, Angular 5 was designed with people’s need in mind and so utilizing its possibilities in the right way is the key. Unlike conventional options, offline experience and push notifications are far better with this latest version. By avoiding unnecessary run time code, the application has now become faster and lighter. With Angular 6 and 7 expected to get released in the upcoming years, the technology world have a lot to hope for. This amazing JavaScript framework was built with the aim to satisfy both users as well as developers.

And if users don’t have your app then it a download button pops up in search results page.

Almost all features can be can be utilized and implemented while using Firebase. However,  they have their own restrictions and trade-offs. For instance, unless your app is running over a unified database that is being edited by the various number of users at the same time and the updates are needed to be notified, the utilization of Firebase is not legitimized. As important review features and functions can be run by MySQL database.

Nevertheless, if you have a business app to be built, then Firebase is one of the best options. With effective and result-driven features, Firebase is all you need to launch your application.

Firebase Security Rules control the access that users of your web apps have to read and write your database. The real-time database rules help determine who can use how much data, the structure of your data and how indexes work. Once defined properly, these rules remain active on Firebase servers and are applied automatically all the time. Users’ request to read and write will be fulfilled only if your rules consider it fair and allowable.

Firebase rules recognize authenticated users and allow them full access to your database by default. This sensible approach keeps at bay undesirable access and protects your database from being abused. You can always customize your rules around authentication, though. However, it is not always easy to set up Firebase security rules to protect database. Let’s learn more about all the necessary tips to use Firebase rules for web apps.

Tips To Use Firebase Security Rules To Build Incredible Web Apps-ad banner

Introduction to Firebase security

Firebase real-time security is comprised of handy tools for web app developers to manage the overall security for the app. With Firebase authentication and validation tools running on server, it becomes easy to:

  • Authenticate users
  • Limit their access to database
  • Define permissions
  • Validate inputs/functions

The quintessential aspect of Firebase-powered apps is that it handles more client-side code unlike other available technology stack in the market. This ensures that your approach to secure your app is unique and deep with strong protective layers within.

The Central Components of Security Rules

There are three major components to Firebase Security rules:

  • User identification
  • Data Access Control
  • Input Validation (to create, read, update & delete Operations)

Once you know user’s identity through Firebase rules, you are allowed to automatically set restrictions for what action they can perform to the database (such as reading, updating or deleting).

The Firebase authentication process involves two options:

1. Firebase UI Auth: This option along with a few good code lines can help establish a complete sign-in system in your app for Web, iOS and Android. It will ask for user email, password, Google+, Facebook, GitHub, etc.

2. Firebase SDK Authentication: This one allows complete freedom to manage authentication based on your choice. You can also opt for Facebook and Google Sign in as Valid Identity providers.

The successful sign-in gives you access to user’s basic profile which is useful while controlling user’s access to stored data.

Firebase Database Rules

The security of Firebase is attributed to powerful JSON-formatted security language. Due to its great flexibility, you can easily access and define rules in Firebase Console using Database->Rules tab.

Firebase Security Rules structure contains syntax like JavaScript and is divided in four types:

.read: Defines when and if users are allowed to read data.

.write: Determines if and when users can write data.

.validate: It defines a value in a correct format and its child attributes and data type.

.indexOn: Specifies a child to index to support ordering and querying.

Firebase Authentication Process

Identifying your users is a basic and the first step when it comes to securing your app. As all users have unique story and profile, their data and capabilities vary from person to person. In chat apps, users are allowed to create messages and delete them if they wish. Deleting messages sent by other users is impossible, though.

Through firebase authentication, users can sign in to your app. It involves popularly used authentication practices with inherent support for Google, Twitter or Facebook along with email login, anonymous log-in, etc.


After identifying users, the next step is to limit and control their access to your database. Firebase authentication and Database Rules can be applied to perform data restrictions in several scenarios such as:

  • Strictly authenticated users can access(read) data
  • Authenticated users are allowed to only write to his own node
  • No one can create a new node except users

Built in variables and functions present in the Firebase security rules allow to refer to other paths, authentication information and server-side timestamps. Using similar format of rule that includes user ID obtained from Firebase authentication, you can also grant write access for authenticated users as well.

Data validation Phase

Owing to seamless nature of Firebase database rules, you can easily tweak and apply changes during development process. However, data should remain consistent once your app is finally ready. The validate rule of Firebase is to bring in validation logic with the same expression as used for .read and .write rules. However, validation rules do not cascade and have to be true for .write to come to effect.

Just like .read and .write rules, you can use the same built-in variables and functions to create Validation rules that know all data locations in your database.

Using Predefined Variables

Firebase has certain predefined variables you can find handy to define security rules that restrict, usher, read, write and validate. A few of them are:

auth: Functions as token payload of authenticated users

root : A node that represents the root path in the Firebase database before the attempted operation.

newData : Contains data that exists after the attempted operation

Data : Contains the data that existed before the attempted operation

now:The current time in milliseconds

$ variables:A wildcard path used to represent ids and dynamic child keys.

Defining database indexes

The Firebase Database security makes it possible to order and query data. Indexes are declared with .indexOn rule.

The data of small sizes do not require indexes during development because of ad hoc querying. However, before the app is launched, it is important to specify indexes for your queries so that it will still work when the app is scaled up.


This blog was our attempt to show how Firebase Database and security appears and works for mobile app and web developers while creating incredible web apps. Hope you will learn a few tips you may need for your next mobile or web app development project. You can always find more details about how to set up and define different security rules for user authentication, authorization and validation by reviewing Firebase Security Rules.

The use of Google cloud platform is not something new nowadays. A large user base are making use of its possibilities to save the device space and access the data anytime they lost their phone data. Have you heard about Google cloud functions, a joint venture of the Firebase and Google Cloud Platform teams?

Back-end code is often required for web and mobile applications to perform actions such as processing long running tasks or sending out notifications. The back end runs on a server in case of conventional approach. This phenomenon is made a lot easier than you can think by using firebase cloud functions in which the back-end code runs in the cloud.

For new users who would like to learn more about firebase cloud functions, here is an overview of its features, working and implementation, capabilities and other advantages that made it the talking point.

What are Firebase cloud functions?

This server less compute solution from Google is ideal for setting up event driven applications. The cloud functions in fact help to run backend code automatically as a reaction to the triggered events. And cloud functions for firebase is exclusively for firebase developers that enable them to add server-side code to integrate its features. A collaboration of HTTPS requests and Firebase features lets you trigger events. The Google’s cloud will store your code and a managed environment runs it. So you can be free from the role of managing and scaling the servers of your own.

Integration with Firebase platform:

The use of cloud functions together with Admin SDK lets the integration across firebase features. For third party services integration, there is option to write web hooks on your own. As the cloud functions lessen the boilerplate code, it gives way for easily using Google Cloud and Firebase within your function. The written functions can respond well to events by other Google Cloud and Firebase features.

Types of triggers:

When you write a function, it can respond to events created by Google Cloud features and Firebase which are termed as triggers.

Some of the most common triggers include:

  • Realtime Database Triggers: In this case, users can respond well to changes that occur in the Firebase Real-time Database.
  • Firebase Authentication Triggers: At the time a user account is created or deleted, code is executed in response through Firebase authentication. This trigger gets invoked in many cases such as a user sets up an account and password, a user signs in for the initial time with federated identity provider and more.
  • HTTP Triggers: At times of an HTTP request, such triggers are invoked.
  • Cloud Storage Triggers: A firebase cloud function is executed in case files and folders are uploaded, updated, or deleted in Google Cloud Storage.

Some of the other triggers include Cloud Pub/Sub Triggers, Cloud Firestore Triggers and Crashlytics Triggers.

A function’s lifecycle

The cycle starts off with writing codes for a novel function by the developer. Followed by that, an event provider will be selected. The conditions are then defined according to which the execution of function happens. The function is then deployed by the developer and Firebase takes the role of connecting to the chosen event provider.

Here are the probable step wise happenings of the rest of the function’s cycle:

  • The code gets evoked once the function’s conditions matches the event generated by event provider
  • The instances get cleaned up in case the function remains idle
  • More instances are created by Google in case many events are handled by functions making them busy
  • Once the updated code gets deployed by developer to update function, the older version instances get cleaned up and new instances replace them
  • In case the function gets deleted by the developer, it is followed by cleaning up of instances. The connection or link between the event provider and function also gets removed.

Implementation path

This phase involves three main sections including setting up of cloud functions, followed by writing functions and finally deploying and monitoring.

Let us see in detail:

The Firebase CLI is installed at first. In the particular Firebase project, the cloud functions are initialized.

JavaScript code is written in order to manage events from Google Cloud services, Firebase services and other similar event providers.

The functions are finally deployed by making use of the Firebase CLI. The Firebase console can be used to see and look for through the logs.

Privacy and security

It is common that developers look to power over application logic in server in order to keep away from interference from the client side. As here it is completely insulated from the client side; that is not a problem with Firebase cloud functions. You can be sure about keeping up the privacy and follow what exactly is needed.

Zero maintenance

The maintenance part is the headache for the users handling all platforms but the case is different in Firebase cloud functions which has zero maintenance. All what you have to do is to set out your TypeScript or JavaScript code to the servers with just a single command. Firebase will do the rest by automatically scaling up computing resources to synchronize with the users’ usage patterns. Unlike other platforms, there is nothing to think hard regarding server configuration, provisioning new servers, credentials, or decommissioning old server.

Running code in cloud- key benefits:

When the code is running in the cloud instead of the traditional approach, you can come across various advantages:

  • There is no necessity for you to run your own server and maintain it.
  • In case of the back-end code, an isolated code base can be used
  • The billing is done only for the code’s real executing time
  • High scalability is possible in case of the cloud infrastructure

More use cases with firebase cloud functions:

Apart from the many advantages and benefits when using firebase cloud functions, here you can see the possible user cases:

  • User notifications are send out at times of events
  • Welcome email is send out at time of a user sign up
  • Confirmation emails are send out in case the users subscribe or unsubscribe
  • In order to make the data base clean and up to date, Real-time Database Tasks are performed which are automated
  • In case a user deletes his account, the contents are deleted from the database
  • For a Real-time Database list, the count of elements are tracked
  • Intensive tasks are executed in the cloud itself and not in your data base
  • At the time of uploading of an image into the database, thumbnails for the same are generated automatically
  • Bulk emails can be send to users for particular cases
  • Even in cases of third party services, integration is possible
  • In case of insertion of text into the Real-time Database, Google Translate service helps with the translation
  • Payments are processed in a lot easier way

Firebase cloud functions have in fact set the technology world on fire with its innovative technologies and the way it has positively impacted the whole scenario. In short words, this innovative cloud functions just remain as a folder in your project which contains an index file and their own node modules.

You can simply run your back-end code without giving a second thought. However, organizing them can get messy if you follow an unstructured way. The most accepted solution is to name the files by the way in which it triggers and you can get the most out of this innovative solution.
