Django Workflow and Architecture

What is Django?

Django is a free and open-source web application framework written in Python. A framework is nothing over a group of modules that create development easier. They’re sorted along, and permit you to make applications or websites from associated existing supplies, rather than from scratch.

When you are building a website, you mostly would like the same set of components: how to handle user authentication (signing up, signing in, sign language out), a management panel for your website, forms, how to transfer files, etc.

Frameworks exist to save lots of you from having to reinvent the wheel and to assist alleviate a number of the overhead once you’re building a replacement website and the Django framework is one of all them.

The official project website describes Django as “a high-level Python net framework that encourages fast development and clean, pragmatic style. It takes care of a lot of effort of net development, thus you’ll be able to target writing your app with no need to reinvent the wheel. It’s free and open supply.”

Django offers an enormous assortment of modules that you’ll be able to use on your own. Primarily, frameworks exist to save lots of developers tons of wasted time and headaches and Django isn’t any totally different.

Django Architecture

Django follows the MVT framework for architecture.

  • M stands for Model
  • V stands for View
  • T stands for Template

MVT is generally very similar to that MVC which is a Model, View, and Controller. The distinction between MVC and MVT here is that Django itself will do the work done by the controller half within the MVC design. Django will do this work of the controller by victimization templates. Precisely, the template file may be a mixture of hypertext markup language half and Django example Language conjointly referred to as DTL.

DijangoBenefits of Django Architecture

The Django Framework is predicated on this design and it really communicates between these 3 elements without having to put in writing complicated code. That’s why Django is gaining quality.

This design of Django has numerous blessings like:

1. Rapid Development:

Django design that separates in different components makes it easy for multiple developers to work on different aspects of the same application simultaneously. That’s additionally one among the options of Django.

2. Loosely Coupled:

Django has totally different elements that need one another at bound elements of the application, at each instant, that will increase the safety of the general website. Because the model file can currently solely save on our server instead of saving on the webpage.

3. Ease of Modification:

This can be a crucial fact of development as there is a unit of totally different elements in Django design. If there’s a modification in numerous elements, we tend not to modify it in alternative elements. This can be really one of the special options of Django, as here it provides us a way with more ability of our website than alternative frameworks.

4. Security:

When building high-end internet applications, security becomes a really crucial facet to reflect on. Django understands this concern and provides its best defender to avoid wasting your efforts. Using click-jacking, cross-site scripting, and SQL injections Django builds a robust wall for the application’s safety. User authentication is additionally a crucial feature to securely manage user accounts and passwords that Django provides.

5. Scalable:

Scalability can be understood as an ability of an application to work well when the size or volume of the platform increases. Django works effortlessly during this issue. Websites created with Django have the capability to handle multiple users at one time. Some well-liked websites victimization Django embody Spotify, Netflix, YouTube, Mozilla, Quora, etc.

Creating a New Project in Django

To start a new Django project, run the command below:

[code language=”css”]
django-admin startproject myproject
[/code]

After we run the command above, it will generate the base folder structure for a Django project.

Right now, our myproject directory looks like this:

[code language=”css”]
myproject/ <– higher level folder
|– myproject/ <– django project folder
| |– myproject/
| | |– __init__.py
| | |– settings.py
| | |– urls.py
| | |– wsgi.py
| +– manage.py
[/code]

  • manage.py: a shortcut to use the django-admin command-line utility. It’s used to run management commands related to our project. We will use it to run the development server, run tests, create migrations, and much more.
  • __init__.py: this empty file tells Python that this folder is a Python package.
  • settings.py: this file contains all the project’s configurations. We will refer to this file all the time!
  • urls.py: this file is responsible for mapping the routes and paths in our project. For example, if you want to show something in the URL /about/, you have to map it here first.
  • wsgi.py: this file is a simple gateway interface used for deployment.

Now everything is set up and we can run the server using the below command

[code language=”css”]
python manage.py runserver
[/code]

Now open the URL in a Web browser: http://127.0.0.1:8000 and you should see the success page, which means the server is running correctly.

Creating Django Apps

Django project contains many apps within it. An app can’t run without a project. You can create app by the following command

[code language=”css”]
django-admin startapp articles
[/code]

This will give us the following directory structure:

[code language=”css”]
myproject/
|– myproject/
| |– articles/ <– our new django app!
| | |– migrations/
| | | +– __init__.py
| | |– __init__.py
| | |– admin.py
| | |– apps.py
| | |– models.py
| | |– tests.py
| | +– views.py
| |– myproject/
| | |– __init__.py
| | |– settings.py
| | |– urls.py
| | |– wsgi.py
| +– manage.py
+– venv
[/code]

So, let’s first explore what each file does:

  • migrations: here Django stores some files to keep track of the changes you create in the py file, and to keep the database and the models.py synchronized.
  • admin.py: this is a configuration file for a built-in Django app called Django Admin.
  • apps.py: this is a configuration file of the app itself.
  • models.py: here is where we define the entities of our Web application. The models are translated automatically by Django into database tables.
  • tests.py: this file is used to write unit tests for the app.
  • views.py: this is the file where we handle the request/response cycle of our Web application.

Now that we created our first app, let’s configure our project to use it. Open settings.py file and find installed_apps block.

settings.py

[code language=”css”]
INSTALLED_APPS = [
‘django.contrib.admin’,
‘django.contrib.auth’,
‘django.contrib.contenttypes’,
‘django.contrib.sessions’,
‘django.contrib.messages’,
‘Django.contrib.staticfiles’,
‘articles’
]
[/code]

Here we have added ‘articles’ in the installed apps section. Now the app is ready to run with the Django project.

Configuring Database

By default Django project comes with sqlite3 database but you can customize it to use MySQL or Postgresql as per the requirements.

settings.py

[code language=”css”]
DATABASES = {
‘default’: {
‘ENGINE’: ‘django.db.backends.postgresql_psycopg2’,
‘NAME’: ‘blog’,
‘USER’: ‘postgres’,
‘PASSWORD’: ‘**********’,
‘HOST’: ‘localhost’,
‘PORT’: 5432,
}
}
[/code]

Now your project is connected with Postgres database and ready to run.

So now, we have learned how the MVT pattern works and the structure of the Django application along with the database configuration.

Angular 13: Top New Features and Updates

Angular 13, the latest version of the TypeScript-based web framework was released. The release has brought several essential updates that can be useful for Angular development.

1. TypeScript 4.4 support

TypeScript 4.4 support is now available in Angular 13. It means now we can use many fantastic language features. Moreover, they stopped supporting TypeScript 4.2 and 4.3 also. One breaking change in TypeScript 4.4 that is advantageous for Angular apps is that it no longer implements setters and getters to get a similar type.

The significant highlights of TypeScript 4.4 are:

  • Improved detection of type guards.
  • Default catch variables.
  • Faster incremental builds.
  • The control flow of conditions can be analyzed
  • Symbol and template string pattern index signatures.

2. Version 7.4 of RxJS

The Angular 13 update adds RxJS, a reactive extension for JavaScript, and includes all versions of RxJS up to and including version 7.

For apps created with ng new, RxJS 7.4 has become the default.

Existing RxJS v6.x apps will need to be manually updated with the npm install rxjs@7.4 command. You can always rely on RxJS 7 for new project creation. As for migrations, existing projects should keep on RxJS 6.

3. 100% Ivy and No More Support for View Engine

The legacy View Engine is no longer supported. Now that there is no View engine-specific metadata or older output formats, it eliminates the codebase complicacy and maintenance costs. Ivy is now the only view engine supported by Angular. Ivy can now compile individual components independently of one another, which significantly improves performance and accelerates development times.

By removing the View Engine, Angular can reduce its reliance on ngcc too. There is no more requirement of using ngcc (Angular compatibility compiler) for the libraries created using the latest APF version. The development team can expect quicker compilation as there is no more requirement for metadata and summary files.

4. IE 11 Support Removed

This stands out to be one of the significant Angular 13 features. Angular 13 no longer supports IE11. CSS code paths, build passes, polyfills, special JS, and other parameters that were previously required for IE 11 have now been completely dropped off.

As a result, Angular has grown faster, and it is now easier for Angular to use new browser features like CSS variables and web animations using native web APIs.

During project migration, running the ng update will automatically remove these IE-specific polyfills and reduce the bundle size.

5. Angular CLI Improvements

The Angular CLI is one of the key components of the Angular Puzzle. Angular CLI helps standardize the process of handling the complexities of the modern web development ecosystem by minimizing these complexities on a large scale.

With the release of Angular 13, this framework now includes a persistent build cache as a default feature, which saves built-in results to disk. As a result, the development process will be accelerated. Furthermore, you have complete control over enabling or disabling this feature in current Angular apps.

6. Improvements to Angular testing

The Angular team has made some notable changes to TestBed, which now correctly tears down test environments and modules after each test.

As the DOM now experiences cleaning after tests, developers can anticipate more optimized, less interdependent, less memory-intensive, and quicker tests.

7. Changes to the Angular Package Format (APF)

The Angular Package Format (APF) defines the format and structure of Angular Framework packages and View Engine metadata. It’s an excellent strategy for packaging every third-party library in the web development environment.

Older output formats, including some View Engine-specific metadata, are removed with Angular 13. The updated version of APF will no longer necessitate the use of ngcc. As a result of these library changes, developers can expect faster execution.

8. TestBed updates

The latest Angular update improves the TestBed significantly, as the DOM is cleaned after every test.  In addition to this, the TestBed tears down test modules and environments in a more effective manner.

Therefore, developers using Angular 13 will get faster, less interdependent, memory-intensive, and optimized tests.

9. Creating dynamic components

One Ivy-enabled API update in Angular 13 is a more streamlined method for dynamically constructing a component. ViewContainerRef.create component no longer requires an instantiated factory to construct a component (no longer need to use ComponentFactoryResolver).

Due to the improved ViewContainerRef.createComponent API, it is now possible to create dynamic components with less boilerplate code. Following is an example of creating dynamic components using previous versions of Angular.

[code language=”css”]
@Directive({ … })
export class Test {
constructor(private viewContainerRef: ViewContainerRef,
private componentFactoryResolver:
ComponentFactoryResolver) {}
createMyComponent() {
const componentFactory = this.componentFactoryResolver.
resolveComponentFactory(MyComponent);
this.viewContainerRef.createComponent(componentFactory);
}
}
[/code]

In Angular 13, this code can become as follows.

[code language=”css”]
@Directive({ … })
export class Test {
constructor(private viewContainerRef: ViewContainerRef) {}
createMyComponent() {
this.viewContainerRef.createComponent(MyComponent);
}
}
[/code]

10. NodeJS Support

Node versions older than v12.20.0 are no longer supported by the Angular framework. Web developers might face certain issues while installing different packages if working with older versions.

16.14.2 is the current stable version of NodeJS. For ensuring seamless deployment of your project, it is recommended to install the latest versions of NodeJS.

Conclusion

The Angular team tries to release a new version update every six months. Now that you know the significant updates and features of the all-new Angular 13. Apart from delivering on the Ivy everywhere promise made in Angular 12 and removing the View Engine altogether, Angular 13 has many impressive features and updates. The framework has become more efficient with inline support for fonts, simplified API, components, and CLI improvements.

The release of Angular 13 enhances the web development process so that the Angular developer can create awesome apps to meet modern web development standards.  If you’re still using Angular 12, it’s time to upgrade your next project with new features.

Versatility and approachability are the main qualities that make VueJS more popular. One can quickly start developing applications with VueJS if one knows HTML, CSS, and JavaScript and have a basic understanding.

Web Developers are also appreciating Vue because it gives insights and Vue CLI makes it easy to develop and manage complex projects. VueRouter and Vuex make it possible to create complex business logic and reactive UI that make it extremely flexible. Single page applications can be developed with this modern too and it also supports server-side rendering.

Simplicity, flexibility, and intuitive approach make it an excellent choice for both new and experienced developers. Vue also has a large and helpful community behind it and is backed by an established company.

Benefits of VueJS Application Development:

Let’s have a look at the benefits of VueJS,

1. Great Flexibility

VueJS is one of the highly flexible frameworks. Because it can be used for a wide range of purposes. It is a component-based architecture and each component can be customized to fit any application. Vue has been used for building desktop applications, web applications, and mobile applications and it is also used for building single-page applications (SPAs).

2. Easily Understandable

VueJS is a JavaScript framework used to build beautiful single-page web applications. The key concepts are straightforward and well-defined, so you can easily grasp how they work. VueJS makes it easy for developers to build highly interactive interfaces with intuitive drag-and-drop components. It also provides an easy-to-use API that enables you to connect your app easily with APIs using HTTP requests.

3. Model-View-View Model (MVVM) Architecture

VueJS Model-View-View Model Architecture is a frontend architecture pattern that divides the view into three distinct elements: models, templates, and views. The VueJS Model-View-View Model Architecture pattern is widely used in web applications where multiple components of the application need to be displayed on the page.

The VueJS community and support are very active. The best thing about the Vue.js community is, that is very welcoming and supportive. It has also a valuable resource for questions and advice as well as troubleshooting. VueJS has strong developer tools like a rich command line interface (CLI) with support for Typescript and other features like hot reloading and live to reload when your code changes.

6. Simple Integration

VueJS is a framework for building UI components in a declarative and efficient way. It’s also very easy to integrate with other frameworks, such as React. If you have a Vue component that needs to sync with the backend in some way, you can use Vuex to easily store and retrieve data. VueJS provides a declarative, intuitive way to build complex UIs. It’s easy to use and scales well for large applications with thousands of users.

7. Two-Way Communication

Two-way communication is a communication mechanism in which the sender and receiver can communicate with each other directly. A two-way communication system could be used for a user to send a message to a server in order to request help or information. VueJS has great support for both reactive forms and custom events, so you don’t have to worry about adding extra code if you need to support the features.
