A framework is nothing but a collection of modules that makes the development process easier and faster. Django is also a framework, a Python-based, free and open-source web framework that follows Model-Template-View (MTV) architectural pattern.

## Why Django?


At first, it might seem difficult to determine which framework you should use for your project to successfully bring it to life. It all comes down to your needs and requirements, though.

**Here are some specific factors and conditions that determine [why to choose Django over other frameworks](https://www.djangoproject.com/start/overview/)-**

- If you need to deploy fast (while making changes as you move forward) and you’re concerned about finding solutions once you get stuck then the answer is very simple- Choose Django.
- Also, think about the actual product you want to create. If your app is likely to scale at any time and must be secure from most common vulnerabilities and attacks — you need a reliable framework, just like Django.
- Plus, it’s a great choice if you’re thinking about integrating cutting-edge technology in the future, i.e. Machine Learning.
- Good documentation and supportive community will also be there for you.

## What You Can Do with Django?


Now, this is a very interesting fact because it was first created for the purpose of _**[web development](https://www.habilelabs.io/web-development)**_ for a newspaper publisher. But now, we can use Django in various multiple areas like-

- High-load booking engines or shopping platforms
- Android and iOS mobile apps that support web applications
- Financial platforms with features for analyzing and calculating approximate results.
- Built-in custom CRM systems for internal data
- B2B CRM systems for handling communication between businesses
- Platforms that facilitate communication between two parties, such as a business and a consumer
- Real estate property evaluation systems
- DMS (Documents management system)
- Platforms for handling legal issues like verifying mortgage conditions or lease status.

## Django Website Structure


Django apps are structured so that there is a separation of logic. It supports the Model-Template-View (MTV) architectural pattern on which most of the web frameworks are built. The basic principle is that in each application there are three separate files that handle the three main pieces of logic separately.

- **Model** defines the data structure. This is usually a database and is the base layer of an application.
- **View layer** encapsulates the logic to process the user’s request and returns the response.
- **Template layer** displays some or all of the data to the user with designer-friendly syntax.

![django-best-framework-for-web-development-in-python_2.jpg](https://backend.habilelabs.io/uploads/django_best_framework_for_web_development_in_python_2_592e85cdc5.jpg)


## Django Project Structure


1- Create Project Command


```
django-admin startproject [projectname]
```


```
[projectname]/ - project root
├── [projectname]/ - Django root
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── manage.py
```

**manage.py**

The file contains the code for starting the server, migrating and controlling the project through command-line.

**_ _init_ _.py**

The _ _init_ _.py file is empty and it exists in the project for the sole purpose of telling the python interpreter that this directory is a package. That’s one of the standard rules of python packages.

**settings.py**

The settings.py is the main file where we will be adding all our applications and middleware applications. As the name suggests this is the main settings file of the Django project. This file contains the installed applications and middleware information which are installed on this Django project.

**urls.py**

urls.py file contains the project level URL information. URL is a universal resource locator and it provides you with the address of the resource (images, webpages, and web-applications) and other resources for your website.

## Unique Features of Django Framework


### SEO Optimized


This is a special feature of _**[Django](https://www.habilelabs.io/blog/python-django-is-here-check-whats-new)**_ due to which it has edge over others. SEO is Search Engine Optimization that means to optimize your website in order to improve its ranking on search engines. As we know that the search engines do use some algorithms which sometimes don’t cooperate much with the web-developer.

Since we are creating our website in the human-understandable form and they have to add it in the URL form on the server so that it’s best recognized by the search engine. Django clears that concept by maintaining the website through URLs rather than the IP addresses on the server, which makes it easy for SEO engineers to add the website to the server while the _**[web-developer](https://www.habilelabs.io/blog/complete-seo-guide-for-web-developers)**_ doesn’t have to convert the URL into some numeric code.

That’s the gist of it although it’s not the whole and complete process but for our purpose it’s sufficient.

### High Scalability


Scalability means that at what scope or level, our technology gets to implement. For bigger websites like Instagram, having millions of active users, they generate data in huge amounts (terabytes of data/day). This kind of level requires our system or application to be very precise and error-free.

### Offers High Security


Django is super secure. It is so because it covers the loopholes by-default which were once left open for the backend developer to complete. It has one of the best out-of-the-box security systems that help developers to avoid common security issues, including

- SQL Injection
- Cross-Site Scripting
- Clickjacking


## Wrap-up:


Django is a great framework that handles large volumes of content (e.g., media files), heavy traffic, and deals with complex data, functions or technology like _**[machine learning](https://www.habilelabs.io/blog/a-complete-guide-machine-learning-model-to-api)**_. It is also useful to scale your project to a much higher level. Do follow us for more similar Tech Blogs.

Django- Best Framework for Web Development in Python

Facebook launched a new open-source JavaScript engine named ‘Hermes’ to improve the performance of React Native mobile apps on Android.

For months, team Facebook was continuously working on improving JavaScript codes and platforms to enhance the performance of Facebook Apps. After analyzing the performance data, they noticed that the JavaScript engine itself was a significant factor in startup performance and download size. So, they worked on optimizing JavaScript performance in the more constrained environments and designed ‘Hermes’. The team has not planned yet to expand the project to browsers or servers such as _**[NodeJS](https://www.habilelabs.io/blog/best-practice-for-node-js-folder-structure)**_.

We’ll learn more about Hermes in here. Let’s dive in then-

## Overview About Hermes-


[Hermes](http://hermesengine.dev/docs/building-and-running/) is specifically built to fasten the startup of applications using static optimization and compact bytecode. It improves the startup time, app size and memory utilization of the applications.

In a blog, Facebook wrote-


>“Hermes improves React Native performance by decreasing memory utilization, reducing download size, and decreasing the time it takes for the app to become usable or “time to interactive” (TTI).”

Hermes improves some core attributes of an application that ensure its high-performance, that are-

- Time to Interact (TTI)- It launches the apps faster decreasing the start-up time by bytecode precompilation.
- Download Size (APK File Size)- Being smaller in size, it starts instantly without weighing down the app.
- Reduction in memory utilization
- Ahead-of-time Static Optimization
- No JIT (Just-In-Time) Compiler
- Compressed Bytecode
- Bytecode Precompilation
- Garbage Collector Strategy with noncontagious, defragmented and On-demand Virtual Address (VA) memory allocation features.
- Lazy Compilation
- Targets the ES6 Specification
- JSI, a lightweight API to embed a JavaScript engine to C ++ applications to ease migration to Hermes.

![javascript-engine-for-react-native_1.jpg](https://backend.habilelabs.io/uploads/javascript_engine_for_react_native_1_53bb2fd23e.jpg)


As you can see in the picture, the TTI has been reduced by 2.29 seconds, the APK file size has been decreased by 19 MB and the memory utilization has been lessened by 49 MB. As a result of this decrement, there has been a substantial improvement for the React Native applications.

## Byte Precompilation


Usually, a JavaScript engine parses the JS source, once it gets loaded and generates bytecode further. This step delays the script execution.

Hermes skips this step and uses an ahead-of-time compiler which runs along with the application build process and optimizes the bytecode and thus makes it smaller and more efficient.

With Hermes, the bytecode is designed in such a way that it can be mapped and interpreted without reading the entire file which leads to improving TTI significantly.


Though this bytecode is a bit larger than the compressed JavaScript code, Hermes reduces the overall application size for React Native Apps.

## How to Use Hermes in React Native App?


To use Hermes in a React Native App includes three main steps-

- Make a Hermes npm Package
- Registering of this npm package with Yarn
- Linking of Hermes with the _**[React Native App](https://www.habilelabs.io/blog/monorepo-for-react-native-apps-with-nx)**_.

Now, let’s discuss how to accomplish all these tasks-

### Make a Hermes npm Package
The Hermes npm package consists of CLI tools, to compile the JavaScript to bytecode, and debugged versions of native Hermes library for Android. However, in order to compile the native libraries for android, you need to set up an appropriate development environment.

- To build a debugged version of Hermes CLI tools, below-given steps should be followed on **macOS/Linux**-


```
mkdir hermes_workingdir
cd hermes_workingdir
git clone https://github.com/facebook/hermes.git
hermes/utils/build/build_llvm.py
hermes/utils/build/configure.py
cd build
ninja
```

- In the case of **Windows,** the following steps should be adhered to-


```
mkdir hermes_workingdir
cd hermes_workingdir
git -c core.autocrlf=false clone https://github.com/facebook/hermes.git
hermes/utils/build/build_llvm.py --build-system='Visual Studio 16 2019' --cmake-flags='-A x64' --distribute
hermes/utils/build/configure.py --build-system='Visual Studio 16 2019' --cmake-flags='-A x64 -DLLVM_ENABLE_LTO=OFF' --distribute
cd build
MSBuild.exe ALL_BUILD.vcxproj /p:Configuration=Release
```

### Register the Package with Yarn


- At the very first step, you need to run the following command to build the cross-compiled LLVM-


```
(cd $HERMES_WS_DIR && ./hermes/utils/crosscompile_llvm.sh
```

- Now, you can build Hermes libraries for Android platforms and package everything together-


```
(cd $HERMES_WS_DIR/build_release && ninja github-cli-release)
(cd $HERMES_WS_DIR/hermes/android && gradle githubRelease)
cp $HERMES_WS_DIR/build_android/distributions/hermes-runtime-android-v*.tar.gz $HERMES_WS_DIR/hermes/npm
cp $HERMES_WS_DIR/build_release/github/hermes-cli-*-v*.tar.gz $HERMES_WS_DIR/hermes/npm
cd $HERMES_WS_DIR/hermes/npm && yarn install && yarn run prepack-dev)
cd $HERMES_WS_DIR/hermes/npm && yarn link)
```

The final command of the **yarn link** will register the Hermes package to Yarn for inclusion to local projects.

### Link the Package with the React Native App


Now, the final step is to link the **npm** Hermes package with your app. Let’s suppose for instance that your project is in the directory **$user_project**, you would run the following command-


```
(cd $user_project/node_modules/react-native && yarn link hermes-engine)
```

Now, you can develop the app in the normal manner.

## Bottom Line


You can download Hermes from Github. The detailed guide of instructions has been provided there as well. Facebook has been quite about using this specific word ‘Hermes’ but you would have heard that Hermes is the god of messenger according to Ancient Greek Mythology.

However, you can make your own assumptions. Stay connected with us for more Latest Tech Releases.

Hermes- A New JavaScript Engine for React Native

Manual testing, as the name suggests, is the method of executing the test cases and differentiating the actual results to the expected results. Test cases are executed manually by a human eye without any support from tools or scripts.

It is done to find bugs in software under development. It is a classical method of _**[all testing types](https://www.habilelabs.io/testing-solutions)**_ and helps find bugs in software products.

## Human Brain is Irreplaceable



>Wonders can happen when the human brain is at work.

![why_manual-testing-is-important-benefits-of-manual-testing_1.jpg](https://backend.habilelabs.io/uploads/why_manual_testing_is_important_benefits_of_manual_testing_1_f4b3d4ec07.jpg)


Only a human can create valid test designs, foresee defects, and execute designs to get the expected result. Human testers will quickly detect when something looks “Off” and can anticipate other failures that sometimes go unnoticed during automation testing. There is no replacement for the human eye.

## User Experience


It is not possible to do the UX/UI testing through automation. A manual tester can spot contextual, functional, visual, and usability bugs that automation scripts may not identify.

![why_manual-testing-is-important-benefits-of-manual-testing_2.jpg](https://backend.habilelabs.io/uploads/why_manual_testing_is_important_benefits_of_manual_testing_2_4c2db74f45.jpg)


For example, the automated tools can’t test for visual considerations like gestures, image color or font size. Testing functionalities like gestures, tap, shake, CAPTCHA, and video control-based trigger actions using automated scripts still need a lot of effort and time.

## Not All Domains Prefer Automation


There are still some domains that prefer Manual testing over Automation testing for most of the system functionality.

The BFSI (Banking, Financial Services, and Insurance) domain is the biggest user of IT services. Banking Applications directly deal with highly confidential financial data. It is obligatory that all the _**[testing activities performed](https://www.habilelabs.io/blog/how-to-test-performance-testing-using-jmeter)**_ by banking software run smoothly and without any error.

![why_manual-testing-is-important-benefits-of-manual-testing_3.jpg](https://backend.habilelabs.io/uploads/why_manual_testing_is_important_benefits_of_manual_testing_3_fca4d7723e.jpg)


You cannot cover everything by Automation such as:

- Total coverage of all banking workflows and Business Requirements
- The functional aspect of the application
- The security aspect of the application
- Data Integrity
- Concurrency

## Un-Automatable Scenarios


Several times, situations arise when there are runtime variations in the functionality of some components either as an enhancement or behavioral change. In this case, the time and knowledge of functionality play a major role.

Now before starting the automated testing, the tester has to set up test cases, program it into the automated tool, and then run the tests. But with manual testing, the QA can quickly test and see the results. Automatic tests take more time as we require the new automation script to run those tests, which definitely will be time-consuming.

![why_manual-testing-is-important-benefits-of-manual-testing_4.jpg](https://backend.habilelabs.io/uploads/why_manual_testing_is_important_benefits_of_manual_testing_4_fc16223633.jpg)


Recently came around one application where the client needs to verify the tap-and-pay function for their mobile wallet app. Developing a way to automate this scenario is not worth it and not possible but when compared to manual testing this can be done easily.

## Testing Perspectives


Negative testing can be done more rigorously via manual testing. If an automation test fails, you will get to know only about the result of the failed test cases and could not perform a workaround to test other areas even if one thing fails.

In such scenarios, only manual testing can be performed. Defects found through Ad hoc testing are typically the results of testing complicated cases that might not have been addressed through your predefined automated test cases.


## Mobile Application Testing

![why_manual-testing-is-important-benefits-of-manual-testing_5.jpg](https://backend.habilelabs.io/uploads/why_manual_testing_is_important_benefits_of_manual_testing_5_4130989d07.jpg)


In Mobile Application Testing Device, compatibility and interactions can’t be covered with automated scripts. Things like leaving and re-entering wi-fi, simultaneously running other apps, device permissions, and receiving calls and texts can all potentially wreak havoc on the performance of an app.

Changing swipe directions from left to right and the number of fingers used for tapping on the phone can also affect mobile apps. Clearly you need a manual tester to address a little touchy-feely if you want your app to have the minimum number of freak-outs. In such scenarios, Automation testing is not worthy enough to spend time on it.


## Bottom Line


To optimize the price and time needed to test any software, you cannot entirely rely upon the automation testing approach. You need the right combination of manual testing and _**[automation testing](https://www.habilelabs.io/blog/automation-using-cypress-end-to-end-testing-tool)**_ to get error-free software.

In a world filled with trends, I would like to stay Classic -Manual Testing

You would have heard it often that “Where a ME may lose, a WE win”. A team consists of multiple talented minds that can deal with any problem. But how to build a TEAM?? Here comes the role of a LEADER.

A leader is the one who transforms a group of people into a team, brings out the best out of their diverse _**[skills](https://www.habilelabs.io/blog/soft-skills-an-important-aspect-of-a-developers-life)**_ and creates an atmosphere of mutual understanding and teamwork. And, it is a daunting task (literally!!).

But how to become an ideal team leader?? This question arises in every new leader’s mind. Here, we have shared some notable qualities of the leaders that you can follow:-

## How to be a True Leader??


Leadership is a very delicate form of art. Being a leader, your very first responsibility is to keep your team together. You need to earn their respect because they have no choice other than to follow your orders, do not misunderstand that they want to follow.

You cannot change their mindset but you can surely create an environment where they want to. When they willingly start trusting your decisions and following all your orders, that will be the day when you can toast for your victory.

### 1- Become an Example!!


The first and foremost rule for the leaders is to ‘Learn to follow’. You can’t become a leading identity just by ordering all around. You will have to contribute to each and every task equally with a positive attitude. Leaders need to set an example before others. For instance, to make your team punctual, improve your timings first.

You must act before others & follow the orders yourself only then they will follow you, with their own will. And then you will win!!

### 2- Take Responsibility, Not the Credit!!


Stay behind your team at the time of success and be the front-face in case of failure. The best living example of such personality is the one-and-only Mahendra Singh Dhoni, a complete pack of all leadership qualities.

Your team looks towards you to take action in every situation. The best quality you can learn from him is to lead in case of failures and take responsibility for the loss (No matter whose fault it is!!) while leaving the fame and credit to others in case of _**[success](https://www.habilelabs.io/blog/keys-to-a-successful-business)**_.

### 3- Unite the Diverse Talent!!


A team is a group of people, having different skills, coming together to bring out the revolutionizing outcomes. Firstly, you should help them out to know their potential and encourage them to leave their comfort zone. You should divide the task between the team members according to their skills and they will love it. When people with diverse talents work together, they create wonders!!

### 4- Communicate Actively!!


Direct and _**[effective communication](https://www.habilelabs.io/blog/how-to-improve-your-communication-skills-effective-tips)**_ brings transparency that further helps to gain the team’s confidence over you. Share everything with them, whether good or bad. Hear out the concerns of your team as well. Listen to their ideas and suggestion and give them a chance to ask questions and argue with you.

You need to make sure that each and every member of the team is participating actively in the discussion. Don’t feel embarrassed even if you are proven wrong, in fact, praise them. An important point here to be noted is that you need to show genuine interest and curiosity to their ideas, otherwise you won’t get expected results.

### 5- Be a Little Empathetic!!


Act like a human, not a robot. You need to be aware of everyone’s downtimes personally. A little empathy and humility build a better understanding. Showing your emotions sometimes like sharing a smile, joking around, going out & having fun with them will cheer them a lot. These small outings have been proven more effective than any team-building exercise.

### 6- Appreciate the Efforts!!


Avoidance and ignorance always do more harm than the hardcore hate!! A leader needs to recognize and appreciate the efforts of his team when your ultimate boss fails to do so. Give them credit for the mass-success and it will motivate them the most rather than some motivational lecture.

Take their suggestions and feedback on a regular basis and let them know their importance. Listen to everyone’s ideas, reward their hard-work, praise the improvements, respect their vision and sometimes let them take the final call.

### 7- Be a Leader, Not Boss!!


Don’t act bossy all-around. Yes, strictness is compulsory sometimes, but there is a very fine line between being a boss and being a leader. Your real accomplishments are defined by this very difference. While a boss seeks out for excuses, takes the complete credit and blames the team for failures, a leader chases the solutions, takes the blame for failures and shares the credit with the team. _**[Leadership](https://www.habilelabs.io/blog/effective-leadership-listen-learn-and-lead)**_ is all about equality and it applies to you as well.

Don’t consider your authority as the power to control. Authority comes with a huge load of responsibilities, responsibility to lead, to face the failures, to keep everyone satisfied, to take the right decisions, etc.

## Conclusion:


A team leader should have a positive attitude to understand his/her team members. You have to accept your flaws as well and keep working consistently to improve them.

Hope you found this blog useful. I am sure, these points will help you become an inspiring and successful leader. Keep connected with us for more similar blogs.

How to Be a Successful Team Leader?

The world of business is a bit mysterious, as at every stage of the business- from the very start-up to the building of an empire- one cannot feel sure about its consistency. Starting a business is tough, but ensuring its success is far more difficult. It is your vision and state-of-mind that will determine the future of your business.

>According to you, what factors specify that a particular business setup will succeed or not? The answer is very simple, only one thing- Customers!! Next comes the Profit. So, the ultimate challenge is to create an audience. More the customers, higher the revenue-growth!! This journey from ‘Ordinary to Extraordinary’ is overwhelmingly hard but not impossible.


## Here, I am providing ‘9 Important Keys to Make Your Business Successful’-

### 1- Know Your Audience/ Customers
Consistency is the ultimate goal that every businessman is working hard to attain. “Focus on customers more than the profit itself and the profit will be all yours.” This is the ‘Key Mantra’ to _**[heighten your business](https://www.habilelabs.io/blog/improving-business-outcomes-with-integration)**_. If you can create an audience for your product, you have already won the half-battle.

![9_keys_to_a_successful_business_1.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_1_e427dd4d26.jpg)


Once you get a customer base, you need to understand them, what do they want and how can your products benefit them and ease their lives. A business can only be sustained if its clients and customers are satisfied with its services. You should deliver the services which will meet their needs, that too, in a cost-effective manner.

### 2- Quality at Fair Price
Quality is the factor that standardizes a business in the market. But what if this quality is provided at a reasonable price?? It sounds like a perfect deal. This combination can raise your sales by multiple times. Quality ensures that the customer take interest in your product but the price is what decides the traffic of customers.

![9_keys_to_a_successful_business_2.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_2_023433c1a5.jpg)


If your product is new in the market then you need to present various aspects to the customers regarding its quality and need in their life, which may take some time. The better and safe approach is to modify the already-accepted product, add some unique and high-quality features, lower the price and see the magic.

### 3- Enhance Your Marketing Efforts

![9_keys_to_a_successful_business_3.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_3_024ba1ba2c.jpg)


Convincing a customer is a tough task. The sales of your products or services considerably depend upon how effective your marketing strategies are. You have to reach the platform where you can easily connect to the customers. If your direct marketing tactics are not working then you should take an indirect approach which includes digital marketing and SEO.

### 4- Keep Analyzing Your Competitors

Keeping a track of your competitor’s activity is not a sign of weakness but a smart move of winners. The market is way similar to a battlefield. In ancient times, rulers fought to get a hold on the common-people while in this battle, companies compete to get hold of the customers.

![9_keys_to_a_successful_business_4.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_4_b07e93a515.jpg)


Think and plan about ‘how can you provide better deals than others?’ and then start working on it.

### 5- Trending & Demanding Products
The success of a business setup solely relies upon the customers. The services or products provided by the company should be demanding throughout the global population. Keep studying the market and point out the most trending & demanding products in a list. Now, go through the list and check out that if you can provide a modified version of any of these products. If yes, then it will be like ‘Bull’s Eye’ for your _**[business growth](https://www.habilelabs.io/blog/re-engineer-your-business-growth-with-offshoring)**_.

### 6- Improve Your Customer Services

![9_keys_to_a_successful_business_5.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_5_420ebfbb95.jpg)


Customer Services are the front-face of every business which shows its originality. If your customer-support-end is not quick-responsive and functional, it will affect your business to a great extent. You should be focused upon providing better services to your customers so that they will look forward to you next time instead of your competition. If you can keep your customers happy and satisfied, it will be a truly great achievement.

### 7- Strengthen Your SEO & Digital Marketing Side
Digital Marketing is the scenario which can bring a start-up to an extraordinary level, that too, in a short span of time. If you can place yourself on the first page of Google Search, well it will be a win-win situation for your business.

![9_keys_to_a_successful_business_6.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_6_a2ebb9f9a3.jpg)


If your business is completely online then you should work towards its Search Engine Optimization. Create your business pages on various social networking websites such as Facebook, Instagram, LinkedIn, etc., respond to the customer’s inquiries and post regular updates there. It will channelize the users to your website which will further improve your google ranking and eventually enhance the sales.

### 8- Be Ready to Take Estimated Risk
People consider the business as a synonym of risk and it truly is. One cannot be certain in his/her business because of many restricting factors such as Cash Flow and Stock Market. If your business provides _**[IT services](https://www.habilelabs.io/services)**_ then the limitation is clients and projects. At a time, you have tens of projects and at another moment, nothing. But you have to take that much risk. It doesn’t mean that you should close your eyes and walk on the cliff, but you should be ready to take estimated risks.

### 9- Team-Work & Collaboration

![9_keys_to_a_successful_business_7.jpg](https://backend.habilelabs.io/uploads/9_keys_to_a_successful_business_7_f027d533ff.jpg)


Team-work leads towards brilliance. A proficient team enhances the efficiency and productivity of a business. When you would be failing, your talented and trustworthy team will be there to share your burden. A single ‘I’ cannot manage the whole business and its employees; you need a strong team to work together with genuine collaboration to achieve a common goal. When a solo mind fails, the team-effort wins.
