How To Optimize Performance With GZIP Compression
Published: 2023-10-03 10:46:05

In this article, I will explain to you one of the very common topics of performance optimization in Node.js express application. While working with any type of application we need to think a lot about performance optimization.

 

When we come to Node.js express framework specifically, We can improve the performance and save the bandwidth by using GZIP compression. It mainly decreases the downloadable amount of data to serve the user.

When a user makes a request to Node.js server, Normally it does not compress the response anyway.

### Let's Get Started
We can use the compression middleware in our main file of Node.js app to enable GZIP which will support compression schemes. This will compact the JSON response and other static files response. 

 
Now install the npm package by typing **npm install compression --save** over the terminal. After installing it, When using this module with express or connect, simply app.use the module as high as you like. Requests that pass through the middleware will be compressed. Have a look below:

``````const compression = require('compression')
const express = require('express')
 
const app = express()
 
// compress all responses
app.use(compression())
 
// add all routes``````

### Understand with an example:

``````const express = require('express');
const compression = require('compression')
const app = express();
 
let oneDay = 24 * 60 * 60 * 1000;
 
// compress all responses
app.use(compression());
 
// Caches the static files for a year.
app.use('/', express.static(__dirname + '/public/', { maxAge: oneDay }));
 
app.get('/',function(req,res){
res.send('welcome to jsonworld');
});
 
app.listen(3000,function(){
console.log('app running on port 3000');
});``````

### Conclusion
So in this demo, We learned how to optimize performance with GZIP Compression. Find here other [nodejs sample application](https://jsonworld.com/blog/how-to-optimize-performance-with-gzip-compression) 


That’s all for now. Thank you for reading and I hope this demo will be very helpful to understand how to optimize performance with GZIP Compression.

Selenium for Automation and its uses
Published: 2023-10-03 10:45:03

        **Selenium** is an open source , automated testing tool used to validate the web applications across different browsers and different operating systems. 
Selenium is widely used testing tool due to the following reasons.
1) As Selenium is developed in javascript, it is easy to use.
2)It helps to test various web applications against various web browsers like Firefox, Chrome, Opera, Safari
3)Selenium supports multiple coding languages like Java, Python, Perl, PHP, Ruby 
4)It can be deployed on any operating system which includes Windows, Linux etc. 
So it is platform independent.
5) For test management support, Selenium can be integrated with tools like JUnit and TestNG 
       The only drawback with Selenium is that it can only be used for web applications and not mobile or desktop applications.

        Selenium comes with a package of tools which is termed as **Selenium Suite of tools** for easy testing of web applications.
It includes the following:
1)Selenium Integrated Development Environment(IDE)
2)Selenium Remote COntrol(RC)
3)Selenium Webdriver
4)Selenium Grid
**Selenium IDE**: It is a browser extension for Firefox or Chrome that automates functionality. Selenium IDE records user interactions on browser and exports them as reusable script. It is used to speed up the creation of automation scripts.
IDE does not support data-driven testing and database testing and cannot provide a detailed test report.
**Selenium RC**: It is a server written in Java that makes provision for writing tests in various programming languages like java, python, C# etc. The RC server accepts commands from the user program and passes them to browser as Selenium core Javascript commands which were initially used before the invention of RC . 
**Selenium Webdriver**: It was the first cross-platform testing framework that could configure and control the browsers at Operating system level. It supports various programming languages like Python, Ruby, PHP etc and can be integrated with TestNG and JUnit for test management.
Selenium test script is the test code written in any programming language that can be interpreted by the driver. Through JSON wire protocol, data is transferred between server and client. Selenium uses drivers specific to each browser to establish a connection and supports various web browsers to test and run the applications.
**Selenium Grid**: It allows parallel execution of tests on different browsers and different operating systems. The Grid consists of a hub connected to several nodes. It receives the information about the OS and browser to be run on and accordingly picks a node that satisfies the requirements and passes the test to that node.
We use Selenium widely for the following reasons:
1) It is open-source
2) Selenium supports a lot of programming languages like Python, PHP, Perl etc.
3)It is extremely reliable as it gives accurate results.
4)Supports various browsers like Chrome, Firefox , Opera etc.
5)It has plenty of re-usability and add-ons.

Hello Dev.to 1 Post about me
Tags: docker, devops, security, management
Published: 2023-10-03 10:17:55

Hello, 
As I'm new to dev.to This is my first post. 
My name is Jānis and I'm from Latvia. I have Explored studied IT since I was 13 years old as at first it was my passion but then it grew as a hobby and after that, it became my career, I started as a System Administrator and grew my way to DevOps after growing into DevOps I started to go forward to become a DevSecOps as I adore automation and how the systems can be automated, I also like to explore and understand the unknown. As a system administrator, DevOps and DevSecOps you work with a lot of systems and challenges like security threats and hacker attacks, so in parallel since the age of  15 I also started to explore the CyberSecurity field so all my career paths in parallel I have been exploring and learning CyberSecurity and slowly growing into that field also, so I can say, that I'm not a strange there also. But in 2023 I started to learn Team Management, so I think my feature will maybe lend there, but who knows as nothing is predictable each day we learn something new, and each day something changes. I believe that Communication and Learning are key also identifying your mistakes and not giving up on difficulties, but facing them and trying until you succeed. My IT career has taught me that you should not give up and try until you succeed or you get the system, or solution working as you like it with quality and sustainability.

Success doesn't teach us, but the failure gives us a lesson. If we succeed well it is done, but nothing is learned if we fail we evaluate our mistakes and learn from them so that in the future we become much better and knowledgeable and don't fail. 

I like puzzles and IT for me is like a large puzzle, that I like to solve. 

Currently, I'm working in a Bank, and additionally each day I learn something new in Team management and IT. As I love to learn and explore, also I'm exploring new things about what I write in my blog https://www.valters.eu/#blog and since 2023-09 I started to learn and create videos for my YouTube channel, So please don't be a stranger read, follow, like, share for cool new tech things:

Blog: [https://www.valters.eu/#blog](https://www.valters.eu/#blog)
YouTube: [http://youtube.com/@valters_eu](http://youtube.com/@valters_eu)

So that's short about me, let's follow each other know more about each other and maybe one day work on some project together.

Tailwind Elements Stable v1.0.0.  - a free, open-source UI Kit with 500+ components integrated with Angular - is out. 
And we couldn't be prouder, so give it a go [here](https://tailwind-elements.com/docs/standard/integrations/angular-integration/)  :) 

It will change Your life (or at least how smooth & painless web development is) ;)

It's stable & reliable, comes with over 500 UI Components, easy theming & customization, dark mode, Figma design system AND free hosting :) 

Angular is a great technology, no doubt, but it has a bit of a steeper learning curve then most others. Can't be easier than with TE though, without losing the traditional Angular benefits: two-way data binding, dependency Injection etc. 

So if you're gearing up for an enterprise-level application, CRM system or dynamic web applications of any kind, check out TE stable v1.0.0! TE has all components & plugins needed for such projects (interactive datatables, advanced charts, forms etc.) and more!  

For all JS aficionados: By default all components have autoinit which means they are initialized by data attributes. But if you want to make init by JS - there is also possibility to do that. 

Check out how to do it and more about Tailwind Elements [here](https://tailwind-elements.com/docs/standard/integrations/angular-integration/)  

Even though TE is already a fully functional UI Kit, it's still in its infancy really - we have great plans and a long and exciting road ahead of us. So whatever input (however critical) You might have, please share it with us here or on any of our channels on which we will be more than happy to host you:

What is a Wildcard SSL Certificate for Website Security?
Tags: cybersecurity, ssl, https, security
Published: 2023-10-03 09:50:15

![What is Wildcard SSl Certificate](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zmcsyij3u2e4u3hcqk20.jpg)An SSL certificate is a pivotal component of website security for any business organization that encrypts data transmitted across a user’s browser and a website server, enabling secure communication between them.

For complex websites with sub-domains, it is also essential to provide security not just for the main domain but also for its sub-domains. Thus, installing a single SSL/TLS certificate for each sub-domain is a costly and time-consuming process, which can be avoided by using a Wildcard SSL certificate.

A Wildcard SSL is a type of digital security certificate designed to provide HTTPS encryption for the primary domain and all of its associated sub-domains using a single certificate, such as a certificate for _*.sample.com_, which also secures _sample.com, www.sample.com, blog.sample.com, about.sample.com_, and so on.

Moreover, every [Wildcard SSL certificate](https://certera.com/ssl-types/wildcard-ssl-certificates) comprises one root domain and one wildcard character represented by an **asterisk (*)** to the left side of the usual name in the subdomain area, denoting its type among different SSL variants.

## Benefits of Wildcard SSL Certificate
Wildcard SSL certificate is enhanced with several benefits such as;
 
**1. 256-Bit Encryption and Security**
**2. Cost Effective Solution**
**3.Simplified SSL Certificate Management** 
**4. High Flexibility**
**5. Conveniency of avoiding Individual SSL for each Sub-domains.**
**6. Boost User trust with padlock icon and using "https://" in the URL.**
**7. SEO Benefits**
**8. Faster Deployment**

Composables
Tags: android, jetpackcompose
Published: 2023-10-03 09:38:50

A composable function is annotated with the @Composable annotation, which tells the compiler that this function can be used in the composition of the UI.

When a composable function is called, it creates a new composition scope. Inside this scope, other composable functions can be called, allowing for the creation of nested UI elements. This is similar to how a layout XML file defines nested views.

```
@Composable
fun MyButton() {
    Column(
        modifier = Modifier.fillMaxWidth().padding(16.dp),
        verticalArrangement = Arrangement.Center,
        horizontalGravity = Alignment.CenterHorizontally
    ) {
        Button(
            onClick = { /* Perform action */ },
            modifier = Modifier.padding(8.dp),
            text = "Click me!"
        )
    }
}
```

For example, in the previous code sample, the MyButton function is a composable function, which describes a button UI element. It takes no inputs, but it returns a description of a button that can be rendered on the screen. The button is created by calling the Button composable, which is provided by the Jetpack Compose library.

Composable functions can also take inputs, such as data or parameters. These inputs can be used to customize the UI elements that are created.
