When programming and working on different projects, developers can optimize processes as these frameworks provide them with basic foundations, making coding easier and faster.
Frameworks and libraries are not the same things. While both are reusable codes written by someone else, they are not synonyms.
On the one hand, libraries are collections of code designed for specific use cases. When developers use them, they call specific functions from the parent code.
On the other hand, frameworks are a more holistic approach. These don’t just offer one solution or one specific function but a complete template for development.
The technical difference is called Inversion of Control (IoC). When using a library, you manage the application’s flow and decide when to call the library for a specific function. However, when you use a framework, it takes charge of the flow as it provides places to plug in your code. It gives you a complete template that adjusts to your needs.
Angular is one of the most popular JS frameworks. It was built by Google to simplify the development and testing process. The framework focuses on building efficient single-page applications, and it supports both MVC and MVW architecture.
Angular uses data binding, which synchronizes data between the database and clients, eliminating from developers the task of defining requests and responses when a user interacts with the UI.
- It’s cross-platform: Developers can build progressive, native, or desktop apps.
- Generates code: The framework transforms templates into highly optimized code for JS virtual machines.
- Its fully customizable
- MVC implementation makes it easier to build a separate client-side application.
- Unit testing: Code is divided into the smallest testable parts (units), making it easier to identify mistakes in each line of the code.
Companies that use Angular:
|Two-way data binding||Requires JS and Typescript knowledge|
|Highly testable products||It has limited SEO capabilities|
|Collection of third-party integrations||Complex and verbose (Not the best option for small applications)|
Built by Facebook, React prioritizes the simplification of building interactive UIs. Developers use React to build and operate the dynamic UI of web pages with high incoming traffic. The framework has functional, declarative, and component-based styles.
React is also characterized by using a virtual DOM (Document Object Model) that makes web applications perform better and faster as these don’t recalculate every time the DOM changes. Additionally, React is declarative and component-based; developers can reuse components to create complex UIs in a short amount of time.
- It’s declarative, making the code readable and easy to debug.
- React uses a Virtual DOM: For every DOM object, there’s a corresponding “virtual DOM object,” which means it creates a virtual copy of the original DOM.
- One-way data-binding: React uses an application architecture called Flux controls. The framework updates the View for the user, and Flux controls the application workflow.
- It’s component-based.
- Offers stable code as it uses downward data flow only (When changes occur in the small structure, the big structure isn’t affected.)
Companies that use React:
|SEO-friendly||Only focuses on the UI layer of applications|
|Ease of integration with front-end and back-end||Complex state management|
|Simplifies the creation of dynamic web applications||Poor documentation (Mostly because of the constant updates)|
Vue.js uses a model-view-ViewModel (MVVM) architectural pattern. This pattern separates the UI from the business logic of the application. It also has a virtual DOM and uses two-way binding as in Angular.
- HTML-based templates: Vue.js provides HTML-based templates that bind the DOM with the Vue.js instance data. These templates are compiled into Virtual DOM render functions.
- Data binding: It allows developers to easily manipulate or assign values to HTML attributes, enabling them to change the style.
- Components help create custom elements that can be reused in HTML.
- Animations and transitions: Vue.js provides various ways to apply transitions to HTML elements when added/updated from the DOM. These include third-party animation libraries.
- Has built-in directives: v-if, v-else, v-show, v-bind, v-on, v-model used on the frontend.
Companies that use Vue.js:
|Lightweight framework||Lack of support for large-scale projects|
|Easy learning curve||Limited resources (It doesn’t have as many plugins as other frameworks)|
|Quick configuration (Thanks to its MVVM architecture).||Language barrier (A lot of the documentation is in Chinese)|
- NodeJS follows a single-threaded model
- Its scalability: As the framework follows an event mechanism that makes the server respond non-blocking, it makes it more scalable than other frameworks.
- Async and event-driven: All APIs of the NodeJS library are async, and therefore, non-blocking.
- Fast: It is a built-in Google Chromes VS JS engine, so it is fast in code execution.
- No buffering: Applications made with Node.js never buffer any data as the application gets out the data in chunks.
Companies using Node.js:
|Scalable||Not suitable for CPU-intensive tasks|
|Robust technology stack||Outdated tooling ecosystem|
|Fast-processing and event-based model||Lacks library support|
Ember.js focuses on building rich and interactive UIs regardless of the website’s size. Its development model is built around HTML and CSS, and it has a component-based approach built off the Handlebars templating engine. Additionally, it focuses on convention over configuration, prioritizing out-of-the-box functionality.
The components in Ember.js are central to the framework, which means that almost everything can be categorized as either service or component. Components can manipulate the markup text and styles of an application user interface. Services are objects that live for an application’s duration and are made for different parts of the application.
- Ember offers routes that are the core features to manage the URL
- It provides the instance initializers
- Ember integrates with large teams
- It has a giant ecosystem with over 1,500 addons
- Follows the principles of Convention over Configuration (CoC) and Don’t Repeat Yourself (DRY)
Companies using Ember.js:
|Great mechanism to work with APIs||High learning curve|
|Supports two-way data binding||Lacks functionality of component reuse|
|Easy upgrades||Scalability issues|
With Svelte, programmers write fewer lines of code that help them save time, reduce bugs, and increase readability. All of this is thanks to its simple format written in TypeScript.
- Mostly used to create interactive web pages
- Less code as Svelte embraces a simple format of writing that is in TypeScript
- It contains out-of-the-box features such as reactive declarations and statements, wait for template blocks, animation and transition helpers, and a debugging helper.
- Built-in animations – Svelte comes with built-in animations and effects. This makes it easy to implement sophisticated UI and interactive behavior.
- Readable stores: Great to deal with immutable data that requires access from different spots on your app.
Companies that use Svelte:
|Great performance||Small community|
|Automated updates||Lacks support|
|Compile code without a virtual DOM||Routing issues|
- It’s reactive: The user interface automatically changes each time there’s a change in data.
- The Meteor package has over 14,079 packages.
- All of the data is synchronized in real-time, facilitating collaboration on a project
- The Meteor framework allows using the same code for the front-end and the back-end and mobile and web applications.
Companies that use Meteor:
|It’s cross-platform||Lacks control mechanism over order of loading files|
|Focuses on the user experience.||No reactive joins|
|Code reuse||Absence of native server-side rendering|
