Bootstrap vs. Angular – Performance Comparison
While performance should not be a killer factor for small projects, it becomes extremely important to consider when building complex and large projects. With that being said, let’s compare Bootstrap and Angular in terms of performance.
How does Bootstrap stand out in terms of performance?
Bootstrap is known for its user-centric ease for developing websites and web applications, but when it comes to performance, one has to keep a close eye on it. Developers have often criticized the framework for its vast library and unutilized resources, leading to slower performance. But, what they miss is that it also offers extensive customization features to increase the app’s performance, irrespective of it being content-heavy.
How does Angular stand out in terms of performance?
When it comes to high-performance frameworks, Angular has proved itself for facilitating superior performance. The framework is powered by Ivy renderer, which is a rewrite of Angular’s rendering engine. It promises to make the applications super quick and compact for unmatched performance and compile components that also reduce its development time.
Bootstrap vs. Angular – Application Architecture
When choosing a framework, it’s important to choose flexibility and avoid any strict enforcement of architecture and guidelines. As a matter of fact, it’s always recommended to treat a framework as a guide, not methods and standards. That said, let’s juxtapose Bootstrap and Angular with each other and check whether they are flexible in terms of architecture.
What kind of architecture does Bootstrap support?
Bootstrap’s architecture can be summarized as a View-View-Controller architecture because of its built that uses two components – Logic Layer and the View Layer. The views component focuses explicitly on the visual displays, while the view-controller sets out all the visual components’ behavior within the framework. There are six modules within the view layer, while the logic layer has twelve components that provide unique functionality to a corresponding visual aid.
Bootstrap supports the Model-View-Controller architecture pattern while developing a webpage. But, it is to be noted that while creating a web application using the MVC design principle, the framework would serve as the view component.
What kind of architecture does Angular support?
Angular has a Model-View-Controller architectural pattern that isolates the application logic from the user interface layer and efficiently supports the separation of concerns. The architecture also helps in organizing the code components according to design and performance variations. It also simplifies the development structure by combining the MVC pattern and two-way data binding.
Unlike other web frameworks, which implement two-way data binding by using fragile event listeners and handlers, Angular makes this process an integral function of its architecture. Moreover, given that the framework isolates the business logic from the UI components, developers are more confident in designing a neat user interface with smooth business logic applicable.
Bootstrap vs. Angular – Ease of Testing
To be able to work without a glitch under continuous, high load, and growing market expectations, your application development project needs to go through a series of tests to ensure compliance with the UI standards, compatibility, and usability. Here’s how Bootstrap and Angular stand out when compared with testing.
How easy is it to test a Bootstrap app?
While there are no internal components within Bootstrap for running tests, external plugins and compatible tools can be used for testing apps and sites made with Bootstrap. One advantage that the framework has is that the cross-browser bugs would be eliminated because of its single coding component that is reusable and does not require any repetition.
However, irrespective of this advantage, running tests across browsers from different devices is necessary to check the application’s consistency and uniformity. External applications that can be utilized for testing a bootstrap application include Chrome Developer Tools, DesignModo, BrowserStack, UIlicious, TestComplete, and many more.
How easy is it to test an Angular app?
Thanks to the dependency injection in Angular, it manages all the scopes and controllers. The unit test functionality in Angular can force dependency injection to perform testing by injecting mock/dummy data into the controller. This process is followed by the assessment of the output and its behavior. What’s more interesting is that Angular also has mock HTTP providers to push fake responses from servers into controllers.
Bootstrap vs. Angular – Scalability
Frameworks significantly influence the web application scalability, therefore, the right choice of framework is important. Here’s how Bootstrap and Angular stand out in terms of scalability.
Is Bootstrap scalable?
Being a mobile-first development framework, Bootstrap can be relied on for making scalable websites and applications. Through Bootstrap, responsive website content can be scaled up or down depending on the browser, application, or screen that the user is using. The framework also omits cross-browser bugs and compatibility issues through its single universal codes and makes it preferable amongst developers.
Bootstrap’s class component allows you to specify column sizes based on the screen sizes and alter the content displayed based on the screens. Furthermore, its interactive grid system also allows creating projects that fit the screen sizes over multiple platforms. So, be it a mobile screen, a tablet, or a laptop, there is a uniformity of aesthetics within the application.
Is Angular scalable?
With continuous support from Google and other established corporations, Angular is a complete framework with the capability to create enterprise-level applications. The scalability of the framework is a result of its powerful command-line interface and feature designs.
Grouping folders and modules based on their features and logical units provides a scalable project structure and easily organizes large codes of a complex application. It is also natural for feature components to keep growing for larger applications, and the suitable action is refracting those into smaller components. Alternatives for improving the scalability include designing the page data model with typescript interfaces and creating a single file for all CRUD operations.
Bootstrap vs. Angular – Suitability for Building Complex Applications
Both Bootstrap and Angular offer official documents, guidelines, open-source projects, and third-party libraries and plugins to support developers throughout the development process. Let’s compare how Bootstrap and Angular fare against each other in terms of building complex apps.
Is Bootstrap suitable for building complex apps?
Being amongst the popular HTML/CSS/JS frontend frameworks, Bootstrap easily passes off for developing complex applications. The framework has a broad range of ready-made components, templates, themes, and other resources that can be utilized depending on the project requirements.
Being a mobile-first framework used for creating responsive websites, Bootstrap can also be used for developing applications that support various platforms, devices, and screens, without having to repeat the codes. Bootstrap’s unique 12 column grid system and visual breakpoints facilitate complex web layouts that can be defined using the predefined grid classes based on viewpoint width. This prevents the cluster of overlapping elements and adjusts designs within a frame that sets the right space amongst its rows and columns.
Is Angular suitable for building complex apps?
Angular is still one of the preferred frontend frameworks used to create complex and large enterprise applications. The most well-known single-page applications like Gmail, Forbes, PayPal have made use of the framework’s architecture for developing complex applications. Its features of limitless scalability allow applications to expand without thinking about their size; reusable codes allow development for multiple platforms; and high performance boosts its speed and user experience. No matter how dynamic the application’s interface is, Angular can turn it into gold for its users.
Bootstrap vs. Angular – Security
It’s only the technology or framework that guides the implementation and management of security controls within an organization. So it’s a necessity that they provide standards or best practices to build secure applications. Let’s compare Bootstrap and Angular in terms of security aspects and check how they fare against each other.
How is security handled in Bootstrap?
It is common for frontend frameworks to have security vulnerabilities, and Bootstrap is also amongst the list that is prone to threats. It is mainly prone to XSS vulnerabilities through the data-target attribute, and developers have reported this threat even over the updated versions. Most vulnerability threats are possible in the tooltip or popover data-temple attribute, affix configuration target property, tooltip data-viewport attribute, data container property of tooltip, data-target attribute, and data-target property of scrollspy.
How is security handled in Angular?
User-generated websites demand a high level of security and management. Cross-site scripting is one of the significant vulnerabilities that the client-side platform needs protection against. These attacks can be prevented by some built-in provisions that the framework provides.
Since there’s no guarantee that attackers won’t enter malicious code through the property, attribute, or any provided value, Angular treats each value as untrustworthy by default. The framework has introduced inner HTML to display the user-generated content and a built-in sanitizer – DomSanitizer – as a security feature. Other security resources include maintaining updated libraries, updating content security policy in security-reviewed code, and using AOT for compiling HTML templates and components. Therefore, following the best practices along with its internal security features and external tools makes Angular a secured framework.

Bootstrap vs. Angular – User Experience
User experience is one vital element in choosing the right framework for your project. It aims to provide positive experiences that keep users loyal to the product or brand. Additionally, a meaningful user experience allows you to define customer journeys on your applications that are most conducive to business success.
Bootstrap’s ability to give the best user experience
Twitter Bootstrap was developed as a web responsive frontend framework to render a standardized and best user experience. The framework’s responsive design gives web users, developers, and viewers consistency across all platforms, which would directly increase the trust and value of the application.
Its readily available templates, themes, drop-down menus, buttons, sliders, plugins built on jQuery, and other interactive components give users a seamless experience through the web application. For enhancing the user experience to a greater degree, Bootstrap UI HTML Kits like Get Shit Done, Shards Dashboard Lite React, Stream can be used. Other free Bootstrap XD UI Kits include Adobe XD Bootstrap 4 UI Kit, Adobe XD Bootstrap 4 Grid Template, Take Me, Universal Web UI Kit.
Angular’s ability to give the best user experience
Angular has emerged as a significant frontend framework in building user interfaces and independently handling the frontend. Since the framework has been divided into components, classes, and segmentations for a clean coding architecture, it manages the users’ interaction through templates. The framework manages the display of data to the users in a sophisticated way. Moreover, the library store is responsible for handling reactivity, and asynchronous programming responsible for making the application responsive to users and their actions.
Providing the template language helps keep the data binding and rendering of HTML on the same page. That means, every time the application page is rendered, the framework interacts with the template syntax and updates the view in no time. Again, keeping no time gap between updating and displaying the information to the users.
Bootstrap vs. Angular – Rapid Development
For projects where low Time to Market (TTM) is essential, it’s imperative to look out whether the framework you choose offers rapid development or not. In our experience, development speed is even more important when your team doesn’t have time to learn a new framework or technology. Having said that, let’s uncover whether Bootstrap and Angular offer rapid development or not.
How does Bootstrap contribute to rapid application development?
The frontend framework is known for quickly developing applications and saves time with the help of its extensive documentation. Being developer-friendly, Bootstrap libraries consist of several class components, making it a framework that doesn’t require coding knowledge to develop an application. You would simply need an understanding of a markup language like HTML and styling basics like CSS preprocessors for implementing Bootstrap in your projects.
The ready-made components, JS plugins, and documented synergy also save time and energy to remember the specifications of each element. Bootstrap’s cross-browser compatibility and consistency reduce the bugs on multiple platforms and aids in upgrading an application within a short span of time.
How does Angular contribute to rapid application development?
What can be more precious for developers to build applications regardless of worrying about huge file sizes? With Angular, developers invest less time and effort, for it lets them reuse codes and streamlining the development process. It brings about more functionality with shorter codes, making it productive for the teams working on back-to-back similar projects.
Angular offers flexibility in coding like no other framework because of its simple design architecture. In terms of flexibility, it allows beginners to get started and make modifications in their application projects seamlessly. Also, Angular handles heavy web applications that are loaded with features and components exceptionally well.
Bootstrap vs. Angular – Application Size
The selection of a framework can have a large impact on the size of an application code. For a large project, the application size should dominate the framework size. Less size is always more in this case. Let’s map out the difference between Bootstrap and Angular in terms of application size.
What is Bootstrap’s application size?
Regardless of the minimum application size, developers would have to be wary of the library packages’ unused components that can bulk up an app. Following the best practices of writing lean HTML and CSS codes, downloading resources from the source code, and minimizing the presentation images would reduce the site’s weight. Bootstrap applications can also be compressed by minifying the JS and CSS codes or using GZIP compression.
What is Angular’s application size?
It is a well-known fact that Angular applications are generally large enterprise-scale applications, so it shouldn’t be a surprise if their size is bigger than expected. Compared to other frontend frameworks and smaller application sizes, medium-sized Angular applications usually range between 250 KB to less than 500 KB. While it is no wonder that larger and complex applications can exceed those figures, one has to resort to using a compiler for compressing the bundle sizes.
Bootstrap vs. Angular – Code Maintainability
A framework should be easier to maintain and adapt. In terms of application development, maintainability means that your developers can easily analyze the code and proceed in fixing errors, thus implementing the correct functionality. That said, let’s analyze how maintainable the code is in the case of Bootstrap and Angular.
How convenient is it to maintain code in Bootstrap apps?
Bootstrap is a UI framework for developing responsive web applications. The class components, utility packages, and template resources are readily available for utilization without writing codes for its development.
The flexibility of class components makes the applications workable for multiple sites and platforms. Thus having a reusable code omits the rewriting process for separate devices. Therefore, the consistency and cross-browser compatibility of the components reduces bugs while developing the application, making it beginner’s friendly for team projects. But, developers have to be wary of the overwriting and customization to make the website unique since Bootstrap inserts unnecessary jQuery plugins within the application.
How convenient is it to maintain code in Angular apps?
For any strong development environment to be successful, code consistency is the key. Thanks to the Angular CLI and documentation style guide, they both drive consistency at the pioneer level. Its feature of reusable code also speeds up the development process for a project with a tight deadline.
