React is one of the most popular front-end web frameworks. It is an open-source JavaScript library used for building user interfaces. It was built by Meta. The framework is used majorly to craft more dynamic user interfaces for single-page applications with frequent UI updates.
Reacts is known for its virtual DOM (Document object model) feature that allows more efficiency, which leads to enhanced performance and user experience.
React JS has gained popularity today because there is a growing need for a front-end framework in the Javascript community for modern web development.
This blog will help you understand:
React majorly aids applications by handling the view layer. It provides efficient rendering execution. Such efficiency is possible because rather than perceiving the whole user interface as a single unit, React helps developers break them into individual reusable components.
Owing to this, React JS allows a much faster web page rendering time than other JavaScript frameworks, producing highly dynamic and responsive web applications.
But, what is React JS?
The conventional way a website works is by sending requests back and forth (between the client and the browser) each time a user opens a new web page. Even though this process is efficient by itself, Facebook’s software engineers wanted to provide a more efficient way for users to interact with the website.
So, they developed a front-end library that does not go about this process in such a redundant way.
It had the ability to build a single-page application that loads a single HTML document on the first request and then updates specific parts of the webpage using JavaScript.
Thus, without reloading a full page, the client can get better performance and a more dynamic experience.
The platform uses virtual DOM, which is a copy of the actual DOM. Once the changes are reflected in the virtual DOM, React compares both DOMs and recognizes the parts of the webpage that are modified.
Then, without rendering the actual DOM, React reflects the changes very efficiently to enable you to not reload entire pages every time something updates.
React allows flexible coding, unlike other frameworks such as Angular. Unlike other frameworks where developers have to set strict rules for code conventions or file organizations, developers can leave the operating powers to React. The model carries out operations as it sees fit according to how the user has described the result.
In React, the HTML code is called JSX or JavaScript XML. It allows developers to take a step back from some additional steps, such as DOM (Document Object Model) manipulation, element selectors, and other constituents that enable them to create concise and convenient code.
That was a brief introduction to React JS. But there is a lot more to uncover, keep reading!
After getting an introduction to React JS, the first thing you might want to know would be real-life examples.
React has several examples you could get inspired from. Check out these:
From creating the genius solution to leveraging it to update real-time time features such as likes, comments, and status updates- Facebook owes its growth as a dynamic website to React.js.
React provides high-performance user interactions through swift and high-performance user interactions.
The list is long, with many other notable high-performing websites such as Reddit, Uber, Airbnb, and several others.
Part of introduction to react JS is getting to know the key terms used by the language.
A reusable piece of code that can describe the structure and behavior of a specific part of a user interface is a website called a React component.
To use React components, you write HTML. This code should have an ending and a beginning, or it can be self-closing. React components also have attributes called properties.
A state is an object within react that represents the current condition of an individual component and determines the way it should render. You can look at it as a collection of all variables needed within a component to make it function.
As discussed already, props are like attributes on HTML elements. Props or properties are the paths through which variables are passed from parent components to child components.
Okay, but what is “declarative programming”?
While working with JavaScript, you might have passed on an order to the computer through an if/then statement. That is called imperative programming.
The only problem with such methods is that they tend to get more cumbersome as the complexity of the code increases, i.e., as the number of choices a user can make increases.
Declarative programming enables you to describe the results to the computer such that it understands the desired output or result. It produces an output based on this description.
With that too covered, we have gone through a pretty detailed introduction to React JS. Now let us talk about how we can put it to use.
Here is how you would start your react JS development.
The GitHub repository is the starting place for building and running a Single page application in the React module on a HubSpot page. It also offers a bunch of documents and resources.
However, according to a few credible sources, you will need a workaround for this process.
The need for a workaround to this process is because of two main reasons. One is that React requires a compilation called Babel, and the HubL code cannot be used inside JSX as they are not compatible with each other.
Now, GitHub repository code is just as usable, but it is an unnecessarily long code, considering that it displays only a single component.
Here is the recommended way of breaking down this repository:
In the `src/modules/app.module`, <script>window.addEventListener('DOMContentLoaded', function() { tag with type as `application/json` is defined to entail the HubSpot CMS module content. The HubSpot CMS user enters module content.
In the `src/index.js`, the <script> tag is parsed to pass on the module content to React component.
Alternatively, from the authenticated resources shared by the HubSpot product team, you can also use React in HubSpot by building an app locally using the HubSpot CLI. Once that is done, you need to run this code:
hs create react-app
Which redirects you to the HubSpot boilerplate react app- this is the GitHub repository we were talking about earlier.
Hope we were able to solve your queries regarding react js development. If you have particular questions to be answered, you might have to hire react js developer to have it solved.
We have talked about the upside of using React on HubSpot. You might be tempted to use the module after such a detailed Introduction to React JS.
Before you hire react JS developer, here are a few challenges as well that you need to be aware of.
Hire HubSpot developer to know if these vulnerabilities will affect your project or not.
