What is Svelte?


Svelte is a JavaScript framework for building web applications. It is a component-based framework that uses a new approach to building web applications, in which the framework compiles components at build time rather than interpreting them at runtime. This allows Svelte applications to be lightweight and fast, with a smaller codebase and lower memory overhead than other frameworks.


Svelte is designed to be easy to learn and use, with a simple syntax and a focus on writing reusable components. It is also designed to be flexible and extensible, allowing developers to integrate it with other tools and libraries as needed. Svelte is a relatively new framework, but it has gained popularity due to its performance and ease of use.





Svelte Features:


Components: Svelte is a component-based framework, which means that it allows developers to build web applications using reusable components.


Compilation: Svelte compiles components at build time, rather than interpreting them at runtime. This allows Svelte applications to be lightweight and fast, with a smaller codebase and lower memory overhead.


Simple syntax: Svelte has a simple syntax that is easy to learn, with a focus on writing reusable components.


No virtual DOM: Svelte does not use a virtual DOM (Document Object Model), which means that it does not need to update the DOM in the same way as other frameworks. This can make Svelte applications faster and more efficient.


State management: Svelte provides built-in support for state management, allowing developers to easily manage the data that flows through their applications.


Animations: Svelte provides support for creating smooth, performant animations using a declarative syntax.


Server-side rendering: Svelte can be used to build server-rendered applications, allowing developers to build applications that are optimized for search engines and improve the initial load time.


Svelte vs React

Svelte and React are both JavaScript frameworks that are used for building web applications. Both frameworks are popular and have their own strengths and weaknesses. Here are some key differences between Svelte and React:

Compilation vs interpretation: Svelte compiles components at build time, while React interprets them at runtime. This means that Svelte applications tend to be faster and have a smaller codebase, but they also require a build step. React, on the other hand, does not require a build step, but its applications may be slower and have a larger codebase.


Syntax: Svelte has a simple syntax that is easy to learn, with a focus on writing reusable components. React uses a virtual DOM (Document Object Model) and a JSX syntax that can be more complex to learn.


Ecosystem: React has a larger ecosystem and a longer history, with a wider range of available libraries and tools. Svelte is a newer framework with a smaller ecosystem, but it is growing rapidly.


Learning curve: Svelte has a shorter learning curve due to its simple syntax and lack of a virtual DOM. React has a longer learning curve due to its more complex syntax and use of a virtual DOM.

Ultimately, the choice between Svelte and React will depend on the specific needs and preferences of the developer and the project. Both frameworks have their own strengths and can be effective tools for building web applications.

What is Micro Frontends Part -1

The term Micro Frontends first came up in ThoughtWorks Technology Radar at the end of 2016. It extends the concepts of micro services to the frontend world. The current trend is to build a feature-rich and powerful browser application, aka single page app, which sits on top of a micro service architecture. Over time the frontend layer, often developed by a separate team, grows and gets more difficult to maintain. That’s what we call a Frontend Monolith . The idea behind Micro Frontends is to think about a website or web app as a composition of features which are owned by independent teams. Each team has a distinct area of business or mission it cares about and specialises in. A team is cross functional and develops its features end-to-end, from database to user interface.

Things to consider when adopting Cloud Computing

    If you are someone who is new cloud computing and is deciding to adopt cloud computing, there are several factors you have to consider. Define the role of Cloud :  Are you looking to host your website or a mobile app or you just require storage space for your files.  Business flows and Priorities of the Solution :  At what point, does your cloud solution fit in. Do I already have a system which I need to upgrade. Find the priorities of the system of your business. Need for Integrations with Internal and External systems :  Based on your application needs, we need to figure out the Internal and External services that is essential part or something you cannot replace with your new cloud solution. Once we identify these sub systems and find a possible way to work with your Cloud Framework. Financials of running the solution:  Running a cloud deployment can be cost effective or a costly affair, based on how it is setup. Different services have differen...

CORS - Cross-origin resource sharing

By Nicho Antony Today, there are many applications that depend on APIs to access different resources. Some of the popular APIs include weather, time, and fonts.  There are also servers that host these APIs and ensure that information is delivered to websites and other end points. Therefore, making cross-origin calls, is a popular use case for the modern web application.  Let’s say accessing images, videos, iframes, or scripts from another server. This means that the website is accessing resources from a different origin or domain. When building an application to serve up these resources with Express, a request to such external origins may fail. This is where CORS comes in to handle cross-origin requests.  What is CORS?   CORS stands for Cross-Origin Resource Sharing. It allows us to relax the security applied to an API. This is done by bypassing the Access-Control-Allow-Origin headers, which specify which origins can access the API.  In other words, CORS is a br...
