Linear algebra tools
Statistical tools
Now, let’s have an insight into ML frameworks that will help you in selecting the right framework for your ML application.

Don’t Miss Out on These 5 Machine Learning Frameworks of 2019
#1 TensorFlow
TensorFlow is an open-source software library for data-based programming across multiple tasks. The framework is based on computational graphs which is essentially a network of codes. Each node represents a mathematical operation that runs some function as simple or as complex as multivariate analysis. This framework is said to be best among all the ML libraries as it supports regressions, classifications, and neural networks like complicated tasks and algorithms.

machine learning frameworks
This machine learning library demands additional efforts while learning TensorFlow Python framework. Your job becomes easy in the n-dimensional array of the framework when you have grasped the Python frameworks and libraries.

The benefits of this framework are flexibility. TensorFlow allows non-automatic migration to newer versions. It runs on the GPU, CPU, servers, desktops, and mobile devices. It provides auto differentiation and performance. There are a few goliaths like Airbus, Twitter, IBM, who have innovatively used the TensorFlow frameworks.

#2 FireBase ML Kit
Firebase machine learning framework is a library that allows effortless, minimal code, with highly accurate, pre-trained deep models. We at Space-O Technologies use this machine learning technology for image classification and object detection. The Firebase framework offers models both locally and on the Google Cloud.

machine learning frameworks
This is one of our ML tutorials to make you understand the Firebase frameworks. First of all, we collected photos of empty glass, half watered glass, full watered glass, and targeted into the machine learning algorithms. This helped the machine to search and analyze according to the nature, behavior, and patterns of the object placed in front of it.

The first photo that we targeted through machine learning algorithms was to recognize an empty glass. Thus, the app did its analysis and search for the correct answer, we provided it with certain empty glass images prior to the experiment.
The other photo that we targeted was a half water glass. The core of the machine learning app is to assemble data and to manage it as per its analysis. It was able to recognize the image accurately because of the little bits and pieces of the glass given to it beforehand.
The last one is a full glass recognition image.
Note: For correct recognition, there has to be 1 label that carries at least 100 images of a particular object.

#3 CAFFE (Convolutional Architecture for Fast Feature Embedding)
CAFFE framework is the fastest way to apply deep neural networks. It is the best machine learning framework known for its model-Zoo a pre-trained ML model that is capable of performing a great variety of tasks. Image classification, machine vision, recommender system are some of the tasks performed easily through this ML library.

machine learning frameworks
This framework is majorly written in CPP. It can run on multiple hardware and can switch between CPU and GPU with the use of a single flag. It has systematically organized the structure of Mat lab and python interface.

Now, if you have to make a machine learning app development, then it is mainly used in academic research projects and to design startups prototypes. It is the aptest machine learning technology for research experiments and industry deployment. At a time this framework can manage 60 million pictures every day with a solitary Nvidia K40 GPU.

#4 Apache Spark
The Apache Spark machine learning is a cluster-computing framework written in different languages like Java, Scala, R, and Python. Spark’s machine learning library, MLlib is considered as foundational for the Spark’s success. Building MLlib on top of Spark makes it possible to tackle the distinct needs of a single tool instead of many disjointed ones.

machine learning frameworks
The advantages of such ML library lower learning curves, less complex development and production environments, which ultimately results in a shorter time to deliver high-performing models. The key benefit of MLlib is that it allows data scientists to solve multiple data problems in addition to their machine learning problems.

It can easily solve graph computations (via GraphX), streaming (real-time calculations), and real-time interactive query processing with Spark SQL and DataFrames. The data professionals can focus on solving the data problems instead of learning and maintaining a different tool for each scenario.

#5 Scikit-Learn
Scikit-learn is said to be one of the greatest feats of Python community. This machine learning framework efficiently handles data mining and supports multiple practical tasks. It is built on foundations like SciPy, Numpy, and matplotlib. This framework is known for supervised & unsupervised learning algorithms as well as cross-validation. The Scikit learn is largely written in Python with some core algorithms in Cython to achieve performance.

machine learning frameworks
The machine learning framework can work on multiple tasks without compromising on speed. There are some remarkable machine learning apps using this framework like Spotify, Evernote, AWeber, Inria.

With the help of machine learning to build iOS apps, Android apps powered by ML have become quite an easy process. With this emerging technology trend varieties of available data, computational processing has become cheaper and more powerful, and affordable data storage.

Nodejs gives you the power to write server side code using JavaScript. In fact, it is very easy and fast to create a web server using Nodejs. There are several frameworks available on Node package manager which makes the development even easier and faster.

But there are a few challenges in Nodejs development:

  • Nodejs is all about callbacks, and with more and more callbacks you end up with a situation called callback hell.
  • Writing readable code.
  • Writing maintainable code.
  • You don't get much intellisense support which makes development slow.

If you are quite experienced and have a good knowledge of Nodejs, you can use different techniques and try to minimize these challenges.

The best way to solve these problems is by using modern JavaScript ES6, ES7 or TypeScript, whatever you feel comfortable with. I recommend TypeScript, because it provides intillisense support for every word of code which makes your development faster.

So I created a framework called FortJs which is very easy to learn and use. FortJs enables you to write server-side code using ES6 or TypeScript which is modular, secure, and pretty much just beautiful and readable.


Some of the important features of FortJs are:

  • Based on Fort architecture.
  • MVC Framework and follows OOPS approach so everything is class and object.
  • Provides components - Wall, Shield and Guard. Components help modularize the application.
  • Uses ES6 async/await or promise for executing asychronous code.
  • Everything is configurable - you can configure your session store, view engine, websocket etc.
  • Dependency Injection.
  • Everything can be unit tested, so you can use a TDD approach.
Let's Code

In this article I am going to create a REST API using FortJs and ES6. But you can use the same code and steps to implement using TypeScript too.

Project Setup

FortJs provides a CLI - fort-creator. This helps you set up the project and develop faster. Let's use the CLI to develop.

Perform the below steps sequentially:

  • Open your terminal or command prompt.
  • Install FortJs globally - run the command "npm i fort-creator -g". Note: Make sure you have Nodejs installed in your system.
  • Create a new project - run the command "fort-creator new my-app". Here “my-app” is the name of the app, so you can choose any name. The CLI will prompt you to choose the language with two options: TypeScript and JavaScript. Choose your language by using the arrow keys and press enter. Since I'm going to use ES6, I have chosen JavaScript. It will take some time to create the project, so please wait until you see "new project my-app created".
  • Enter into the project directory - "cd my-app".
    Start the development server with live reloading - run the command "fort-creator start".
  • Open the browser and type the URL - http://localhost:4000/.

You should see something like this in the browser.

Let's understand how this page is rendered:

  • Open the project folder in your favourite code editor. I am going to use VS Code. You will see many folders inside project root such as controllers, views, etc. Every folder is grouped by their use - for example, the controllers folder contains all controllers and the views folder contains all views.

  • Open the controllers folder -> Inside the controllers, you will see a file name - default_controller. Let's open it and observe the code. The file contains a class DefaultController - this is a controller class and it contains methods which return some http response.

  • Inside the class DefaultController, you will see a method 'index' - this is the one which is rendering current output to the browser. The method is known as worker in FortJs because they do some kind of work and return the result as an http response. Let's observe the index method code:

    const data = {
       title: title
    const result = await viewResult('default/index.html', data);
    return result;

    It creates a data object and passes that object into the viewResult method. The viewResult method takes two parameters - the view location and view data. The work of viewResult is to render the view and return a response, which we are seeing in the browser.

  • Let's find the view code and understand it. Open the views folder - > open default folder - > open index.html. This is our view code. It is simple HTML code along with some mustache syntax. The default view engine for Fortjs is mustache.

I hope you have understood the project architecture. If you are having any difficulties or doubts, please feel free to ask in the comments section.

Now we will move to next part of this article where we will learn how to create a simple rest API.


We are going to create a REST endpoint for entity user - which will perform CRUD operations for the user such as adding a user, deleting a user, getting a user, and updating a user.

According to REST:

  1. Adding user - should be done using the http method "POST"
  2. Deleting user - should be done using the http method "REMOVE"
  3. Getting user - should be done using the http method "GET"
  4. Updating user - should be done using the http method "PUT"

For creating an endpoint, we need to create a Controller similar to the default controller explained earlier.

Execute the command  "fort-creator add". It will ask you to "Choose the component to add ?" Choose Controller & press enter. Enter the controller name "User" and press enter.

Now that we have created the user controller we need to inform FortJs by adding it to routes. The route is used to map our controller to a path.

Since our entity is user, "/user" will be a good route. Let's add it. Open routes.js inside the root directory of the project and add UserController to routes.

After adding UserController, routes.js will look like this:

import { DefaultController } from "./controllers/default_controller";
import { UserController } from "./controllers/user_controller";

export const routes = [{
    path: "/*",
    controller: DefaultController
    path: "/user",
    controller: UserController


So when an http request has the path "/user" then UserController will be called.

Let's open the url - http://localhost:4000/user.

Note: If you have stopped FortJs while adding the controller, please start it again by running the cmd - fort-creator start

And you see a white page right?

This is because we are not returning anything from the index method and thus we get a blank response. Let's return a text "Hello World" from the index method. Add the below code inside the index method and save:

return textResult('Hello World');

Refresh the url - http://localhost:4000/user

And you see "Hello World" right?

Now, let's convert "UserController" to a REST API. But before writing code for the REST API, let's create a dummy service which will do CRUD operations for users.


Create a folder called “services” and then a file “user_service.js” inside the folder. Paste the below code inside the file:

const store = {
    users: [{
        id: 1,
        name: "ujjwal",
        address: "Bangalore India",
        emailId: "[email protected]",
        gender: "male",
        password: "admin"

export class UserService {
    getUsers() {
        return store.users;

    addUser(user) {
        const lastUser = store.users[store.users.length - 1]; = lastUser == null ? 1 : + 1;
        return user;

    updateUser(user) {
        const existingUser = store.users.find(qry => ===;
        if (existingUser != null) {
            existingUser.address = user.address;
            existingUser.gender = user.gender;
            existingUser.emailId = user.emailId;
            return true;
        return false;

    getUser(id) {
        return store.users.find(user => === id);

    removeUser(id) {
        const index = store.users.findIndex(user => === id);
        store.users.splice(index, 1);

The above code contains a variable store which contains a collection of users. The method inside the service does operations like add, update, delete, and get on that store.

We will use this service in REST API implementation.


For the route "/user" with the http method "GET", the API should return a list of all users.

In order to implement this, let's rename the "index" method inside user_controller.js to "getUsers" making it semantically correct. Then paste the below code inside the method:

const service = new UserService();
return jsonResult(service.getUsers());

Now user_controller.js looks like this:

import { Controller, DefaultWorker, Worker, textResult, jsonResult } from "fortjs";
import { UserService } from "../services/user_service";

export class UserController extends Controller {

    async getUsers() {
        const service = new UserService();
        return jsonResult(service.getUsers());

Here, we are using the decorator DefaultWorker. The DefaultWorker does two things: it adds the route "/" & the http method "GET". It's a shortcut for this scenario. In the next part, we will use other decorators to customize the route.

Let's test this by calling the url http://localhost:4000/user. You can open this in the browser or use any http client tools like postman or curl.

Ok, so we have successfully created an end point :) .

Let's look again at our code and see if we can make it better:

  1. The service "UserService" is tightly coupled with Controller "UserController" which becomes a problem for unit testing "UserController". So we will use dependency injection by FortJs to inject UserService.
  2. We are creating an instance of "UserService" every time the method getUsers is called. But what we need from "UserService" is a single object and then call the "UserService" method from the object.

So if we can somehow store an object of "UserService" then we can make our code faster (because calling new does some work under the hood). For this we will use the singleton feature of FortJs.

Let's change the user_controller.js code by the below code:

import { Controller, DefaultWorker, Worker, textResult, jsonResult, Singleton } from "fortjs";
import { UserService } from "../services/user_service";

export class UserController extends Controller {

    async getUsers(@Singleton(UserService) service) {
        return jsonResult(service.getUsers());

As you can see, the only change is that we are using the "Singleton" decorator in the method getUsers. This will create a singleton and inject that singleton when getUsers is called. This singleton will be available throughout the application.

Since service is now a parameter, we can manually pass the parameter while calling. This makes getUsers unit testable.

For doing unit testing or E2E testing, please read this test doc -


Let's add a method "addUser" which will extract data from the request body and call service to add a user.

async addUser(@Singleton(UserService) service) {
        const user = {
            gender: this.body.gender,
            address: this.body.address,
            emailId: this.body.emailId,
            password: this.body.password
        const newUser = service.addUser(user);
        return jsonResult(newUser, HTTP_STATUS_CODE.Created);

In the above code we are creating the Singleton of the UserService again. So the question is will it create another object?

No it will be same object that was in getUser. FortJs supplies the object as a parameter when it calls the method.

The methods created are by default not visible for an http request. So in order to make this method visible for the http request, we need to mark this as a worker.

A method is marked as a worker by adding the decorator "Worker". The Worker decorator takes a list of http methods and makes that method available for only those http methods. So let's add the decorator:

async addUser(@Singleton(UserService) service) {
    const user = {
        gender: this.body.gender,
        address: this.body.address,
        emailId: this.body.emailId,
        password: this.body.password
    const newUser = service.addUser(user);
    return jsonResult(newUser, HTTP_STATUS_CODE.Created);

Now the route of this method is the same as the name of the method that is "addUser". You can check this by sending a post request to http://localhost:4000/user/addUser with user data in the body.

But we want the route to be "/", so that it will be a rest API. The route of the worker is configured by using the decorator "Route". Let's change the route now.

async addUser(@Singleton(UserService) service) {
    const user = {
        gender: this.body.gender,
        address: this.body.address,
        emailId: this.body.emailId,
        password: this.body.password
    const newUser = service.addUser(user);
    return jsonResult(newUser, HTTP_STATUS_CODE.Created);

Now our end point is configured for a post request. Let's test this by sending a post request to http://localhost:4000/user/ with user data in the body.

It returns the user created with id which is our logic. So we have created the end point for the post request, but one important thing to do is to validate the data. Validation is an essential part of any app and is very important for a backend application.

So far, our code is clean and readable. But if we add validation code it will become a little dirty.

Worry not, FortJs provides the component Guard for this kind of work. A/c to the FortJs docs:

Guard is security layer on top of Worker. It controls whether a request should be allowed to call the Worker.

So we are going to use guard for validation of the data. Let's create the guard using fort-creator. Execute the command  fort-creator add and choose Guard. Enter the file name "UserValidator". There will be a file "user_validator_guard.js" created inside the guards folder. Open that file.

A guard has access to the body, so you can validate the data inside that. Returning null inside the method check means that we're allowing to call the worker. Returning anything else means block the call.

Let's make it clearer by writing code for the validation. Paste the below code inside the file "user_validator_guard.js":

import { Guard, textResult, HTTP_STATUS_CODE } from "fortjs";

export class UserValidatorGuard extends Guard {

    async check() {
        const user = {
            gender: this.body.gender,
            address: this.body.address,
            emailId: this.body.emailId,
            password: this.body.password
        const errMsg = this.validate(user);
        if (errMsg == null) {
            // pass user to worker method, so that they dont need to parse again  
   = user;
            // returning null means - guard allows request to pass  
            return null;
        } else {
            return textResult(errMsg, HTTP_STATUS_CODE.BadRequest);

    validate(user) {
        let errMessage;
        if ( == null || < 5) {
            errMessage = "name should be minimum 5 characters"
        } else if (user.password == null || user.password.length < 5) {
            errMessage = "password should be minimum 5 characters";
        } else if (user.gender == null || ["male", "female"].indexOf(user.gender) < 0) {
            errMessage = "gender should be either male or female";
        } else if (user.emailId == null || !this.isValidEmail(user.emailId)) {
            errMessage = "email not valid";
        } else if (user.address == null || user.address.length < 10) {
            errMessage = "address length should be greater than 10";
        return errMessage;

    isValidEmail(email) {
        var re = /^(([^<>()\[\]\\.,;:\[email protected]"]+(\.[^<>()\[\]\\.,;:\[email protected]"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
        return re.test(String(email).toLowerCase());


In the above code:

  • We have created a method validate which takes the parameter user. It validates the user & returns the error message if there is a validation error, otherwise null.
  • We are validating data inside the check method, which is part of guard lifecycle. We are validating the user inside it by calling the method validate.
    If the user is valid, then we are passing the user value by using the "data" property and returning null. Returning null means guard has allowed this request and the worker should be called.
  • If a user is not valid, we are returning an error message as a text response with the HTTP code "Bad Request". In this case, execution will stop here and the worker won't be called.

In order to activate this guard for the method addUser, we need to add this on top of addUser. The guard is added by using the decorator "Guards". So let's add the guard:

async addUser(@Singleton(UserService) service) {
    const newUser = service.addUser(;
    return jsonResult(newUser, HTTP_STATUS_CODE.Created);

In the above code:

  • I have added the guard, “UserValidatorGuard” using the decorator Guards.
  • With the guard in the process, we don't need to parse the data from the body anymore inside the worker. Rather, we are reading it from which we are passing from "UserValidatorGuard".
  • The method “addUser” will only be called when Guard allows, which means all data is valid.

One thing to note is that the method "addUser" looks very light after using a component, and it's doing validation too. You can add multiple guards to a worker which gives you the ability to modularize your code into multiple guards and use that guard at multiple places.

Isn't this cool :D?

Let's try adding a user with some invalid data:

As you can see in the screenshot, I have tried sending a request without a password. The result is - "password should be minimum 5 characters". So it means that guard is activated and working perfectly.


Let’s add another method - “updateUser” with route “/” , guard “UserValidatorGuard” (for validation of user) and most important - worker with http method “PUT”.

async updateUser(@Singleton(UserService) service) {
    const user =;
    const userUpdated = service.updateUser(user);
    if (userUpdated === true) {
        return textResult("user updated");
    } else {
        return textResult("invalid user");

The updated code is similar to the addUser code except functionality wise it is updating the data. Here, we have reutilized UserValidatorGuard to validate data.


In order to delete data, user needs to pass the id of the user. This can be passed by:

  • Sending data in body just like we did for add & update - {id:1}
  • Sending data in query string - ?id=1
  • Sending data in route - for this, we need to customize our route - "/user/1"

We have already implemented getting data from body. So let's see other two ways:

Sending Data in Query String

Let's create a method "removeByQueryString" and paste the below code:

async removeByQueryString(@Singleton(UserService) service) {
    // taking id from query string
    const userId = Number(;
    const user = service.getUser(userId);
    if (user != null) {
        return textResult("user deleted");
    } else {
        return textResult("invalid user", 404);

Sending Data in Route

You can parameterise the route by using "{var}" in a route. Let's see how.

Let's create another method "removeByRoute" and paste the below code:

async removeByRoute(@Singleton(UserService) service) {

    // taking id from route
    const userId = Number(;

    const user = service.getUser(userId);
    if (user != null) {
        return textResult("user deleted");
    } else {
        return textResult("invalid user");

The above code is exactly the same as removeByQueryString except that it is extracting the id from the route and using parameter in route i.e., "/{id}" where id is parameter.

Let's test this:

So we have finally created a REST API for all the funtionalities except GETting a particular user by id. I will leave that to you for practice.


Q: How do we add authentication to "UserController", so that any unauthenticated request can't call the "/user" end point.

A: There are multiple approaches for this:

  • We can check in every worker for authentication. (BAD - so much extra work and code repetition)
  • Create a Guard component and assign to every worker . (GOOD)
  • Create a Shield component and assign to controller. Shield is a security layer similar to guard but works on top of controller, so if shield rejects then controller is not initiated. (BEST)

Which Back-End Frameworks better to Learn in 2020

Which Back-End Frameworks better to Learn in 2020

I’ll really love to know which is the best Backend Framework in your choice. In this post, we'll discuss about Back-End Frameworks better to Learn in 2020

Frameworks have become a necessary part of every frontend & backend development in this modern age, as the trend of developments are always growing with the passage of time. It’s absolutely stupid to reinvent the wheel for such advanced techniques, assuming that you can reinvent all that. That’s why using frameworks supported by millions of developers around the world is a very practical method for developing powerful and interactive applications.

Although every backend framework comes with its own set of pros and cons, there are also a few other circumstances you’ll want to take into consideration before making a final decision. In this guide, we’ll take a deeper look at both tried and newer frameworks to help you decide which is the best backend framework for you.

I’ll really love to know which is the best Backend Framework in your choice. In this post, we'll discuss about Back-End Frameworks better to Learn in 2020

What makes a backend framework the best?

Backend frameworks are judged by many factors. In my opinion, a framework should be versatile. Most of the times backend frameworks are ranked by the coding tools, programming languages the support, & interfaces they offer.

List of Best Backend Frameworks

From RESTful APIs to complete MVC frameworks, here are some of the most robust backend frameworks in 2020 you should learn.

1. .Net Core

The main reason why I have chosen .Net Core as the best backend framework is its Versatility.

Are you a Web Developer or want to Develop an App for Mobile or Desktop, If you are a Game Developer or want to work on Machine Learning, your .Net Core knowledge will help you.

Here are the results of Slackoverflow 2018 & 2019 survey comparison.

We can see how quickly .Net & .Net Core has raised fame as compared to the previous year. After .Net 5 news, there’s no doubt that .Net is going to be the best frameworks in future.

Let’s see what is the most loved frameworks according to Stackoverflow survey results.

We can see that .Net Core has remained the most loved framework of 2019.

There’re many Top Programming Languages Surveys available to choose the best programming language but for the best Backend Framework, there’s only one survey by CodingInfinite.

Here are the results of developers survey.

The above stats are really interesting. It shows, when it came to the developers’ community to pick the best backend framework, 66% of developers have chosen .Net Core as their first choice.

2. Express

Express is a fast, minimalist framework of Node.js. It provides a light coating of necessary web application features, without obscuring Node.js features. Furthermore, it’s easy to build powerful Web Services with the help of various HTTP utility methods & middleware available.

A few examples of large websites using Express are: IBM, Uber, Accenture.


  • Unopinionated & Minimalistic
  • Amazing routing API
  • A large number of plugins
  • Setup is simple & straightforward

Express is based on Node.js & Node.JS is on the top on the Stackoverflow Survey result.

Another thing what makes Node.js one of the most popular frameworks is JavaScript. JavaScript the most popular & easy to learn programming language.

3. Django

Django is a powerful Python framework that is built with the idea of including almost everything, a developer would want out of the box. Therefore there is less need for third-party plugins & everything in Django works together. Django however, is built for bigger applications. Therefore, if you’re preparing on developing small applications, Django may not be the most suitable option as it can make a small project bloated with unnecessary features. Big names such as Youtube, Google, & Instagram use this framework.

A few examples of large websites built on Django include: Pinterest, Disqus, Mozilla, National Geographic.


  • Extremely customizable
  • Highly scalable
  • Encourages rapid development, no need to reinvent the wheel,
  • Extensive documentation & community

Python is the most popular language according to PYPL & almost every survey. That’s why developers also want to use their Python knowledge for writing Web Services & developing Powerful Web Applications. That’s one of the reasons why Django’s popularity has increased so quickly.

4. Laravel

The Laravel framework is well-known for building robust We Services & Web Applications. It is loaded with web building components and is said to be full of featured backend web development framework.

Laravel is open-source & follows the MVC design pattern. It is a PHP framework for the development of extensive backend web apps, which helps seamless connectivity with the back-end. It is well equipped with powerful command-line tools and help functions.

Laravel was initially introduced as an open-source PHP framework in 2011. It has become popular because of the intuitive interface, database migration, blade template engine etc.

  • Template Engine
  • Comes with its own CLI
  • Eloquent ORM
  • Powerful template system (Blade)
  • Database Migration System
  • Good documentation

5. Ruby on Rails

RUBY ON RAILS is one of the most popular MVC based web frameworks developed using Ruby programming language & executed on Linux OS. It offers developers a convenient coding environment, with smooth compilation and testing.

It also provides a smooth transition from back end development & testing to the ultimate stages of the development lifecycle. It has built-in security functions and uses a set of add-ons before the launch of the web application.

The following are some of the unique features of the Ruby on Rails framework.

  • Symbol garbage collector
  • Keyword arguments
  • Turbolinks
  • Module #prepend
  • Action Mailer
  • Action cable & Actionpack Assertions
  • Rails API
  • Rake command

Thank you for reading. I’ll really love to know which is the best Backend Framework in your choice.
