Suggested January 2024 Creating A Particle Animation In React Js

“Particle animation” is a technique in game physics, motion graphics, and computer graphics that uses many minute sprites, 3D models, or other graphic objects to simulate certain kinds of “fuzzy” phenomena.

In this article, we will see how to make a popular particle animation in React JS. We will do this using a third-party package called “react-tsparticles”.

First create a React project −

npx create-react-app tutorialpurpose

Go to the project directory −

cd tutorialpurpose Example

Download and install the “react-tsparticles” package −

npm install react-tsparticles react

We will use this package to add default particle animations with different styling elements. You can also add id and different options for different things like particle speed, particle color, background color, particle numbers, particle size, etc.

Add the following lines of code in chúng tôi −

import Particles from "react-tsparticles"; import React from "react"; export default class App extends React.Component { constructor(props) { super(props); } render() { return ( <Particles options={{ background: { color: { value: "#0000", }, }, fpsLimit: 60, interactivity: { detectsOn: "canvas", events: { enable: true, mode: "push", }, onHover: { enable: true, mode: "repulse", }, resize: true, }, modes: { bubble: { distance: 400, duration: 2, opacity: 0.8, size: 40, }, push: { quantity: 4, }, repulse: { distance: 200, duration: 0.4, }, }, }, particles: { color: { value: "#fff", }, links: { color: "#ffffff", distance: 150, enable: true, opacity: 0, width: 1, }, collisions: { enable: true, }, move: { direction: "none", enable: true, outMode: "bounce", random: false, speed: 5, straight: false, }, number: { density: { enable: true, value_area: 800, }, value: 300, }, opacity: { value: 0.5, }, shape: { type: "circle", }, size: { random: true, value: 5, }, }, detectRetina: true, }} ); } } Explanation

In options attribute, you will see many different types of editable value. You can tweak the values to get different kinds of effect, for example,

In shape, you can use “square” to make a square particle.

In size, you can define the size of the particles.

In number, you can define the value of particles, etc.

Output

On execution, it will produce the following output −

Your browser does not support HTML5 video.

Http Cookies In Node Js

The cookies are the data stored in the user’s browser for quick access. For example, whenever we log in to any website, the server returns the access token, which can be stored in the browser’s cookie with the expiry time. So, whenever a user revisits the website, they don’t need to log in to the website repeatedly if the access token stored in the cookies has not expired.

We can also access the browser’s cookies on the server side in NodeJS. After that, we can check if any detailed data exists in the cookies we are looking at, and if not, we can set that data into cookies again.

Here, we will learn to access, set, and clear the cookies using NodeJS.

Syntax

Users can follow the syntax below to set and get the cookies using NodeJS.

res.cookie(“name”, value); });

res.send(req.cookies); });

In the above syntax, we set the cookies in the first route using the ‘res.cookie()’ method and get the cookie using the ‘req.cookies’ in the second route.

Before users start trying the example below, they should have created the Node application. Also, execute the below commands to install the app’s ‘express’ and ‘cookie-parser’ NPM packages.

npm i express cookie-parser Example

In the example below, we have created the basic server using express. Also, we have used the ‘cookieParse’ in the express app.

We show the welcome message whenever users go on the home route after running the application. Also, we have created the car object containing some properties.

Whenever the user goes to the ‘setcookies’ route, it sets the car data in the cookies. Users can go to the ‘getcookies’ route to access all cookies. Users can go on the ‘clear’ route to clear the cookies.

let express = require("express"); let cookieParser = require("cookie-parser"); let app = express(); app.use(cookieParser()); res.send("Express app is created successfully, and you are on homepage"); }); let car = { name: "BMW", model: "X5", price: 50000, }; res.cookie("carData", car); res.send("car data is stored in cookies"); }); res.send(req.cookies); }); res.clearCookie("carData"); res.send("Cookies are cleared!"); }); if (err) throw err; console.log("listening on port 8000"); }); Example 2

In the example below, we set the cookies with the expiry time. We have created the table and homeWindow object containing the various properties in the key-value pair.

We can set both objects with different expiry times by making a get request on the ‘setCookies’ route. Also, users can access and delete particular cookies by passing the name as a parameter. In the output, users can observe that we accessed only table objects.

let express = require("express"); let cookieParser = require("cookie-parser"); let app = express(); app.use(cookieParser()); res.send("Express app is created successfully, and you are on homepage"); }); let table = { color: "brown", material: "wood", size: "small", price: 100, }; let homeWindow = { color: "white", material: "glass", size: "big", price: 200, }; res.send("Cookies are set with different expiry time"); }); res.send(req.cookies); }); res.send(req.cookies[req.params.name]); }); res.clearCookie(req.params.name); res.send("Cookies with name " + chúng tôi + " is deleted"); }); if (err) throw err; console.log("listening on port 8000"); });

Users learned to set and get cookies from NodeJS. We use the res.cookie() method to set cookies and req.cookies to get cookies. Also, we can use the res.clearCookies() method to clear any particular or all cookies.

Creating A Plan For Social Listening

An introduction to issues to consider when starting a social listening or social media monitoring programme What is Social Listening?

Starting with the basics, you need to scope out what you’re looking to use social listening for. Start by defining how you intend to use it to add value to your business. How will you explain it to colleagues. This is how we see it:

“Social listening is a a market research process in which relevant content and conversations, defined by keywords are identified from social media sites such as blogs, social networks, forums & blogs and then placed into context to provide insight to inform customer engagement, collaboration and new product development”.

Later in this post I’ll break this out into 5 potential marketing applications of social media listening that can be considering.

Define your purpose

How you utilise these tools and process will depend on your requirements, internal resource and budget. I have outlined the various uses of such processes to help you identify how you can get the most from this area, yet the critical first step is to be clear on what you’re listening for. For example is your main purpose brand monitoring, conversation and engagement, customer service or just research? Some of the most popular platforms available that can help with these activities are:

You may also find Dave Chaffey’s post which goes into much more detail when comparing social platforms useful.

Application 1. Brand Monitoring

One use of such tools is to monitor your brand online, this will allow you to understand how many times your brand is being mentioned, you can then overlay the sentiment of the conversation as well as how influential those people talking are. Here’s an example of how segments can be defined in Radian6 to review sentiment and intention by a series of competitors.

Metrics to report on performance: Volume of mentions, sentiment, influence of people talking about you

Process: Implement keywords relating to your brand, including any negative matches required to hone in on relevant matches. Run reports weekly vs the previous week, monthly against the previous month and quarterly trending year to date vs last year.

Application 2. Influencer Research

A crucial part of any marketing and campaigns in 2012 is to understand who in the industry / target audience is influential. Influencers become valued partners in campaigns helping you spread your content (should it be worthy of spreading). Influencers are way of creating value to potential customers who probably don’t know you, influencer outreach enables you to create traffic and reach for your campaign or content in ways that more traditional channels cannot.

Metrics to report on performance: Influence score (depending on the tool you use), fans / followers. If relating to a website you may want to bring in metrics such as page rank, inbound links, pages indexed (this would be sourced from other tools though)

Application 3. Reviewing consumer brand engagement

One of the most powerful uses of social listening in my opinion. Monitoring for relevant conversations to your brand, product and campaign allows you to respond and become part of the conversation. Just the fact you are awake enough to do this and equally happy to put the effort in with customers will help grow your business. If it is done well, i.e. your brand uses this to have conversations with customers & influencers not sell to them then you will succeed.

Process: Once the system is configured to monitor the right keywords (relating to brand, products and campaigns) you need to continually monitor for conversations, the art is then determining which conversations / mentions are relevant for you to participate in. As long as you treat as a one on one conversation you are unlikely to go wrong. You should report on the metrics above weekly & monthly.

Application 4. Customer Service

A form of brand & engagement monitoring really (i.e keywords are the same) but the process and requirement is very different. Whether good or bad certain types of people will voice their opinions on products / brands because they now have efficient tools to broadcast those opinions, previously it was over the garden fence or in the local for example. This form of social listening creates a process in which those mentions are processed from a customer relationship viewpoint. Meaning if for example you are Dell and I have just bought a laptop from you which arrived with a broken power adaptor you are going to want to resolve that without damaging the brand. An example of good customer service thanks to social listening would be that my rant online is picked up, due to the intelligence of the tools my email address is matched to a record in the Dell CRM and I am flagged for a response to the rant and call from customer services, oh and my new adapter is in the post. A process run by customer services & guided / helped by brand and marketing managers.

Metrics to report on performance: Sentiment, cases raised, cases successfully resolved, replies / engagement

Application 5. Broader Market Research

A key report / insights work to complete each quarter is to understand your place in the social market place, how are you performing against competitors and what are competitors doing that you maybe are not. This is a detailed piece of work and should be not be taken lightly. Though the value gained through insights to enhance campaigns and ultimately ensure you are improving your performance in comparison is amazing.

Metrics to report on performance: Share of voice, mentions, sentiment, influence

Process: Most social listening platforms have areas to enter competitor key-terms as well as industry relevant terms, this will enable particular views on data and allow analysis comparing mentions, sentiment etc to each other brand and also aggregating scores to give metrics such as share of voice. Once you have the top level data it is then key you drill down into some of the activity causing spikes in your competitors activity, this should be deconstructed and displayed to stakeholders where relevant. Keep to summary paragraphs, data + bullet points so that the report remains actionable.

It would be great to hear your experiences so far of utilising these types of platforms in your business, it was not a well documented or talked about area as yet, so any shared learnings are welcomed.

Creating A Smarter Retail Technology Environment

Increasing customer engagement is a priority for retailers, and the Internet of Things (IoT) is creating a new realm of possibilities for these interactions. As the number of customers who carry smartphones continues to increase, retailers are looking for ways to tap into this technology to provide a more personalized experience. With a new combination of retail technology, which includes beacons, radio frequency identification (RFID) and smart digital displays, retailers are driving the next generation of location-based marketing programs that aims to create more personalized and intimate shopper relationships.

One-to-one customer relationships are closer to reality than ever before. What’s the catalyst driving these interactions? The evolution and proliferation of the smartphone. In the United States alone, 182 million consumers currently own a smartphone, according to a 2023 report from Boston Retail Partners. In the retail setting, these consumers are using their smartphones to read product reviews, compare prices and make purchase decisions. The key to engaging the customer in the buying process is to reach them through their smartphones.

Using In-Store Retail Technology

While marketing efforts based on geo-location and beacons are changing the relationship between retailers and customers, retailers must remain mindful about how they interact with shoppers. “We’re still at the very early stages of one-to-one communications,” said Adebayo Onigbanjo, director of marketing at Zatar, a leading IoT cloud service from Zebra Technologies. “While beacon interactions spur notifications sent directly to consumer phones, retailers must be careful to send customized messages in an appropriate way.”

Bring the IoT Into the Mix

The number of IoT-connected devices will reach 38.5 billion in 2023, a 285 percent increase from 13.4 billion in 2023, according to a 2023 report from Juniper Research. Such devices include smartphones, tablets, smart signage and wearables. Where the rubber meets the road, however, is not only how these devices are connected, but how they communicate, analyze and share their data.

That said, it’s clear why the IoT is becoming a priority for retailers. Once collected, actionable information can be applied toward creating an engaging customer experience. For instance, using data from a smartwatch, retailers will be able to gain insight into how long a customer stands near a product, or the speed at which they wander down the aisle.

Zebra Technologies is illustrating this process through its work with the National Football League (NFL). Almost four years ago, the company created a program with the NFL that embedded RFID tags within player uniforms to track their activity on the field. By pulling actionable data from the active tags, NFL team owners, managers and coaches could push findings to broadcasters, creating “next-generation statistics.”

Based on early successes, it didn’t take long for Zebra through its Zatar initiative to understand the emerging role of the IoT in the customer experience. Thanks to its ability to drive data into the cloud to be merged with other data, RFID technology was quickly considered one of the building blocks of early IoT projects. By building out innovative cloud services, Zatar was ready to expand the power of the IoT in the retail industry, which meant including beacons in the mix.

Creating an Engaging Customer Experience

To make in-store digital signage even more interactive, savvy retailers are integrating beacon technology to detect users with Bluetooth-enabled smart devices as they approach the digital displays. By adding a third element that utilizes RFID technology, brands can further optimize content that is shown on the screen.

Zatar and Samsung are illustrating how retailers can create an engaging customer experience by affixing RFID tags within labels on wine bottles. When a customer carries a RFID-tagged wine bottle past a dedicated reader, the tag prompts a nearby digital sign to serve up customer reviews, merchandise details and even food pairings.

This next level of customer service aims to enhance the relationships customers have with their retailers. “Shoppers want to be personally targeted and engaged,” said Onigbanjo. “The goal is to know your shopper and to use IoT technology to display relevant content that prompts shoppers to take action.”

As the IoT gains traction across the industry, retailers are reevaluating the role of connected devices. By merging a variety of solutions, these companies may finally achieve their goal of fostering intimate, one-to-one shopper relationships.

How To Differentiate Between Manual And Automated Animation In Javascript?

Generally, animation in JavaScript is done to get different effects and make the object move around the page. You can move and animate any type of HTML element using manual or automated animations in JavaScript.

In this tutorial, we will learn how to differentiate between manual and automated animation in JavaScript.

Manual Animation

Before explaining the difference between the two common types of animation used in JavaScript, we must learn the process of animating objects manually.

Under Manual Animation, the animation process is not automated. The following is the implementation of a simple animation using DOM object properties and JavaScript functions as follows. The following list contains different DOM methods.

We are using the JavaScript function getElementById to get a DOM object and then assigning it to a global variable imgObj

We have defined an initialization function init() to initialize imgObj where we have set its position and left attributes

We are calling the initialization function at the time of window load.

Finally, we are calling moveRight() function to increase the left distance by 10 pixels. You could also set it to a negative value to move it to the left side.

Steps

Step 1 − Choose or decide the object or image that needs to be animated manually by the user.

Step 2 − Decide the position and size of the elements.

Example

The following example shows how to create objects or add images that can be moved or animated manually using the moveRight() or moveLeft() functions.

var

imgObj

null

;

function

init

(

)

{

imgObj

document

getElementById

(

‘myImage’

)

;

imgObj

style

position

‘relative’

;

imgObj

style

left

‘0px’

;

}

function

moveRight

(

)

{

imgObj

style

left

parseInt

(

imgObj

style

left

)

‘px’

;

}

window

onload

init

;

Automated animation

Automated animation creates better and more user-friendly software and online games. The main benefit of using automated animation is setting the time for certain effects or movements of the objects.

We will automate the process discussed in the manual animation. We can automate this process by using the JavaScript function setTimeout() as follows −

Here we have added more methods. So let’s see what is new here −

The moveRight() function is calling setTimeout() function to set the position of imgObj.

We have added a new function stop() to clear the timer set by setTimeout() function and to set the object at its initial position.

Steps

Step 1 − Find or create the object that will be used for automated animation.

Step 2 − Choose the initial style and position of the object..

Step 3 − Add a button, if required, to start and stop the animation process.

Step 4 − Determine the time or position where the animation needs to stop or restart.

Example

You can see from the following example that an object can stop animation automatically at a certain point. This example can be used to experiment and find out the scope of automated animation in JavaScript

var

imgObj

null

;

var

animate

;

function

init

(

)

{

imgObj

document

getElementById

(

‘myImage’

)

;

imgObj

style

position

‘relative’

;

imgObj

style

left

‘0px’

;

}

function

moveRight

(

)

{

imgObj

style

left

parseInt

(

imgObj

style

left

)

‘px’

;

animate

setTimeout

(

moveRight

)

;

}

function

stop

(

)

{

clearTimeout

(

animate

)

;

imgObj

style

left

‘0px’

;

}

window

onload

init

;

How do we differentiate between manual and automated animation?

Step 1 − Find out if you have to make manual changes to get the results.

Step 2 − Check the time limit of the animation.

JavaScript Animation with the movement of the mouse

You can see various animations with the movement of the mouse. While creating responsive buttons, images, and other elements, we commonly use JavaScript. In this method, you will see how the image size changes with the movement of the mouse over the element.

Syntax

The following syntax shows how to change the elements using onMoveOver and onMoveOut user behaviors.

if(document.images){ var animation1 = new Image(); var animation2 = new Image(); } onMouseOver = animation2.src; onMouseOut = animation1.src; Example

The following example shows how an object can change its size or position with the movement of the mouse over the element.

(

document

images

)

{

var

animation1

new

Image

(

)

;

var

animation2

new

Image

(

)

;

}

a id

SVG

href

“#”

onMouseOver

“document.myImage.src=animation2.src;”

Using the above method, you can find the number of arguments that have been passed within a JavaScript function. You will see the output of the result by running this code.

How Does React Fragment Work With Examples

Introduction to React Fragment

React Fragments were first launched in the version React 16.2.0. These are used where, earlier, the developers used wrapper div as React Fragments help us group a set of children without adding additional nodes to the DOM. Earlier, the elements were wrapped in a div for returning multiple aspects. This led to some irrelevant markup or rendering of irrelevant HTML, which could have been better for the website. React Fragments solved this problem. This easily returns multiple elements without the need for a wrapper div. This article will explain how to use this with some examples.
