海外TECH	DEV Community	Creating A Reusable Speedometer Component.	https://dev.to/emmanueloluwafemi/creating-a-reusable-speedometer-component-5emm	Creating A Reusable Speedometer Component Working on a project recently I noticed that a speedometer is one of the functional components that are rare to find outside and a lot of developers are finding it so hard to come up with Speedometers can be used as a chart to display constantly updating data to showcase real time changes in something and it gives the user a more friendly appeal they can relate to In this article we will be creating a speedometer component making it reusable and also looking into how to get data dynamically to work with Outline Understanding components structure Understanding trigonometry and how to apply it to UI design Creating project structure Updating data dynamically ConclusionPrerequisitesTo understand this tutorial you will need to have Basic Understanding of react JSNode JS installed on your PCA Text Editor Preferably VS Code Terminal CMD or any other terminals The speedometer part is divided into parts which are the display the speed loader and the indicator bar The display serves as the main screen where info numbers is shown to the users The Speed Loader serves as a moving progress bar to show the user the level they are and last the indicator bar is the pinpoint that rotates around the speedometer as the data changes Understanding TrigonometryTrigonometry is one of the basic mathematics topics introduced in school though they don t mention the use case or how it can be applied it is one of the mathematical solutions that is been applied when it comes to solving motion problems We will be able to work with degrees and see how we can go around a circle From the Project structure we can carve it into a semi circle which is divided into two parts that help to get the centre of the action which is where the circles revolve around This means that all the rotations we will be doing will revolve around the centre of the action Without much talk let s set up the project structure and move into coding the components themselves Project setupSince we will be using react for the project we need to first create a blank react project Then we will install the necessary packages firstly open your terminal and enter this command npx create react app Speedometer Once you have successfully created the project you should see something like this Once you have successfully created the project you should see something like this Then open the code in a text editor and let s clean up the file structure by removing what we will not need there Go to the src folder and delete logo svg reportWebVitals js setupTests js App test js and App css Open index js and replace the code inside with this import React from react import ReactDOM from react dom import index css import App from App ReactDOM render lt React StrictMode gt lt App gt lt React StrictMode gt document getElementById root Open app js and replace the code inside with this also function App return lt div gt Hello World lt div gt export default App Create two folders with the name components and styles and open the components folder and create a file with the name speedometer js inside then open the styles folder and create a file with the name SpeedometerStyle style js and also a file name Wrapper style js We will be using styled components for the styling so we have to install styled components to the project go back to your terminal and install the package using this command yarn add styled componentsNow open the Wrapper style js file and add the following code inside import styled from styled components export const Wrapper styled div width max width vw height vh display flex justify content center align items center background fff Looking at the code above we are importing the styled components package we installed then we are using it to create a style we can be used everywhere on the project as a reusable component the style set the width and height to vw and vh respectively just for it to fill the user s screen and then centralize using flex Just to set up the style for the Speedometer itself open the SpeedometerStyle style js file and add this code import styled from styled components export const StyledSpeedometer styled div width max width px margin top rem guage body width height padding bottom background border top left radius border top right radius position relative overflow hidden Looking at the style above we are creating a rectangle with a width of px to get a semi circle making the guage body width and a padding to the bottom which will give us access to just of the space we have Then we use a border radius to the top left and top right of the rectangle in other to perfectly curve it Lastly we make the position relative so that the body children position can be set independently without issues and overflow as hidden in the other to hide anything going out of the guage body Go to Speedometer js and add the following code import React from react import StyledSpeedometer from styles SpeedometerStyle style import Wrapper from styles Wrapper style const Speedometer gt return lt Wrapper gt lt StyledSpeedometer gt lt div className guage body gt lt div gt lt StyledSpeedometer gt lt Wrapper gt export default SpeedometerLooking at the code above we imported the styled component we created for Wrapper and StyledSpeedometer which is what we are using to construct the layout After the setup let s go to the App js file and replace the code with this import Speedometer from components Speedometer function App return lt Speedometer gt export default App This is just using the speedometer component we have created to display the content If it is successfully implemented we should have something like this when we run the code with yarn start from the terminal Now let s continue add the following line of code inside your Speedometer js file inside the guage body div tag lt div className guage body cover gt lt div className guage indicator slider gt lt div gt lt div className guage indicator gt And open the SpeedometerStyle style js and update the style by adding this style inside the guage body section guage body fill position absolute top left width inherit height background transform origin center top transform rotate turn transition transform s ease in out guage indicator position absolute width px height px top left transform translate transform origin center top transform rotate turn border radius background z index amp before guage indicator slider width px height rem background color transform origin center transform rotate turn margin bottom rem guage body cover width height border radius background fff position absolute top left transform translateX display flex justify content center align items center The output should be something like this Let s move forward by adding the text board to the speedometer to get the numbers as it s changing open your Speedometer js file and update by adding this code to the below guage indicator div lt div className text content gt lt h gt lt h gt lt p gt Mbps lt p gt lt div gt And open the SpeedometerStyle style js and update the style by adding this style immediately after the guage body class text content position absolute top background color top left transform translate z index h font size rem font weight color fff margin padding text align center p font size rem font weight color fff text align center padding margin This style is to add style to the h tag and the paragraph tag then position the text content class to fit where we want it to be We should have something like this once we are doneOur UI is ready The next thing is to make it dynamic so that we can get data from external sources or backend and make it work perfectly without issue Updating Data Dynamically Just to get dummy data to use we will be using random data with the JavaScript Math API so let s create a snippet that generates a number in every second so still inside the Speedometer js file update it by adding a useEffect and add this code inside it should look like this create a state to store the speedconst speed setSpeed useState generates a random number between and every seconduseEffect gt setInterval function setSpeed Math floor Math random Looking at the code above a speed state to store the speed then a useEffect is used to run the interval immediately once the page loads which updates every second and using the Math random function we create a random number from to and store it on the speed state We need to update the speedometer so that we can update it once the speed state change To achieve this we need to create a ref for some of our div tags and also use another useEffect to update it Firstly let s create our ref by creating a ref which will be hooked with some div tags updating the code withconst turnRef React useRef null const sliderRef React useRef null Then update the div tags with this to link the div with the ref lt div className guage body fill ref turnRef gt lt div className guage body cover gt lt div className guage indicator slider ref sliderRef gt lt div gt Lastly let s create another useEffect and add this code insideuseEffect gt const turn speed gt speed turnRef current style transform rotate turn turn sliderRef current style transform rotate turn turn speed Looking at the code above we are using a useEffect that uses the speed as a dependency so that it will update once the speed value changes Then we set a turn value which checks if the speed is greater and equal to If yes then it uses a fixed value which is If no then we will use speed The reason why we are using is that the circle is not complete and to start from the circle cutout we are adding the value to the speed value Once the speed is more than we stop it from going through the cut out by restricting it with a fixed value So it should look like this after the update If everything is done correctly as it is in this tutorial you should get something like this once you run the server again ConclusionCreating this speedometer component actually helps in learning some aspects in react which include a look into trigonometry updating CSS values and dynamically passing data to update CSS value This component can be used in many use cases to suit different purposes including getting the data from a backend and updating the style to suit your need To get this code check it up on GitHub by using this
