Integrate CardConnect Payment with Node.js
Published: 2023-07-18 10:53:45

There are many payment gateways available today for our application. Today, I am going to create a sample application to integrate Node.js application with CardConnect Payment gateway. 

**CardConnect is a payments platform of Fiserv, focused on helping businesses of all sizes grow through the seamless integration of secure payment processing.**



### NPM package required

We will use here Axios package of NPM to connect with CardConnect API.



### Let's Get Started


Create new project folder and create a file named server.js, Have a look on code inside server.js below:

`````` 
const axios = require('axios');
 
const paymentCredential = new Buffer('testing:testing123').toString('base64');
 
const getPaymentAuthToken = async (data) => {
 
  try {
    const config = {
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Basic ${paymentCredential}`
      }
    };
    const URL = 'https://fts.cardconnect.com:6443/cardconnect/rest/auth';
    return await axios.put(URL, data, config);
 
  } catch (error) {
    throw (error);
  }
}
 
const makeCharge = async (data) => {
 
  try {
    const config = {
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Basic ${paymentCredential}`
      }
    };
 
    const URL = 'https://fts.cardconnect.com:6443/cardconnect/rest/capture';
   return await axios.put(URL, data, config);
 
  } catch (error) {
    throw (error);
  }
}
 
(async() => {
  const paymentRequest = await getPaymentAuthToken({
    account: '4444333322221111',
    merchid: '496160873888',
    amount: '1000', // for charging $1.00
    expiry: '1260',
    currency: 'USD'
  });
 
  const charge = await makeCharge({
    merchid: paymentRequest.data.merchid,
    retref: paymentRequest.data.retref
  });
 console.log(charge);
 
})();``````

In the above code, At the top we have method **getPaymentAuthToken** method used for getting auth token for card connect server. Test credentials for sandbox has been used everywhere in the file. In middle there is a makeCharge method which is actually charging the required amount from the card/bank detail.



### Run the app

``````node server.js``````



### Conclusion


Integration of CardConnect payment is very easy with Node.js. If you are new to Node.js then click here find many demos to start the app for enterprise-level application

React SEO: Best Practices To Make Your Website SEO-friendly
Tags: react, seo, developer, development
Published: 2023-07-18 10:36:30

There are various opportunities for any business sector to go digital in the current digital era. To stand out from the crowd, you must optimize your company website. How would potential customers learn about your uniqueness, no matter how amazing your offerings and business practices are, if your website isn't ranking highly in the search engine?

**How React Handles Rendering** 

React uses a virtual DOM to manage rendering. JavaScript code is used to specify the structure and behavior of a React component when it is created. React efficiently updates the virtual DOM rather than the actual DOM when a component's data or state changes. The previous Virtual DOM and the updated Virtual DOM are then compared in a process known as diffing. To put the real DOM in line with the new state, the bare minimal changes must be determined.

**How Google Processes Web Pages**
1. Web crawling  
2. Page fetching  
3. Page parsing  
4. Indexing  
5. Ranking  
6. Search result display  

**SEO Issues in React Applications** 
1. Initial page load  
2. Delayed content indexing  
3. Metadata and title tags  
4. URL structure  
5. Slow initial load times  
6. Crawlability and internal linking  

**Effective Practices for Enhancing SEO in Your React Website** 
1. Server-side rendering (SSR)  
2. Metadata optimization  
3. URL structure  
4. Structured data  
5. Lazy loading and code splitting  
6. Crawlability and navigation  
7. Page speed optimization  

Every day, there is more rivalry in the web development industry. Additionally, SEO tactics are developing quickly. Following the SEO and React development trends is essential if you want to stand out. An effective SEO-optimized website can aid in customer acquisition and retention. You can efficiently design an SEO-friendly website by following the [React best practices](https://neurdesigns.com/resources/react-seo/). By putting the tactics into practice, you'll be better prepared to increase the visibility of your React website and, as a result, its usefulness as a tool for business.

As the passage of time leaves its mark on our skin, the appearance of wrinkles and fine lines becomes an inevitable reality for many. However, thanks to the remarkable advancements in aesthetic medicine, the quest for youthful radiance has become more attainable than ever before.

**FOR TREATMENT BOOKING
VISIT OUR SITE: [Aesthetics By Revolve]**(https://www.aestheticsbyrevolve.co.uk/)


Understanding Anti-Wrinkle Treatments:
Anti-wrinkle treatments are non-invasive cosmetic procedures designed to diminish the appearance of wrinkles and fine lines, primarily in the facial area. These treatments target areas prone to repetitive muscle contractions, such as crow's feet around the eyes, frown lines between the eyebrows, and forehead creases. By relaxing the underlying muscles responsible for these dynamic wrinkles, anti-wrinkle treatments smooth the skin's surface, resulting in a more youthful and rested appearance.

The Treatment Process:
Undergoing an anti-wrinkle treatment is a quick and relatively painless process. During the procedure, a trained and licensed practitioner carefully injects small amounts of Botulinum Toxin into the targeted facial muscles. The injections are precise, ensuring a natural and subtle outcome, while still effectively reducing the appearance of wrinkles. Patients can expect the treatment to take only a few minutes, allowing them to resume their daily activities immediately afterward.

Natural-Looking Results:
One common concern about cosmetic treatments is the fear of looking "overdone" or "frozen." However, when administered by experienced professionals, anti-wrinkle treatments produce natural-looking results. A skilled practitioner will take into account your facial anatomy, expressions, and desired outcome to create a refreshed appearance that maintains your individuality.

Conclusion:
In the pursuit of smoother, younger-looking skin, anti-wrinkle treatments have revolutionized the cosmetic industry, providing a safe and effective solution for facial rejuvenation. With their ability to soften wrinkles, enhance natural beauty, and instill newfound self-confidence, these treatments have become a popular choice for individuals seeking a non-invasive path to youthful radiance.

React Series Part-0
Tags: react, webdev, javascript, beginners
Published: 2023-07-18 10:03:11

Namaste, dear reader!

In this **ReactJS** series, I'll be covering the entire topics of **ReactJS**.

First things first! ReactJS is **library** of Javascript and not a **framework**.It was developed by Facebook in 2011.
>`It is widely and insanely used for creating fast and interactive user interfaces.
ReactJS is way ahead of its potential competitors e.g. Angular JS and Vue js. `

The entire ReactJS application  made up of reusable and independent set of **components**.



![Components are the building blocks of ReactJS App](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mvn5fzubo0mt39i98qlg.png)

Every react app has atleast one component which is referred as the **App component**.
>App component represents the react app and all the components are placed inside it.


![React APP Structure ](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kkvdigb5jiyj89uporqx.png)

Since React is a library, it has a very specific purpose .i.e to create user interfaces also know as **views**.
>`React can also be used in the parts of our existing application and it will not disturb the existing technology of the application. This is one of the major differences between React and Angular.`

Let's see who all are using react.

AntDB Installation and Deployment Documentation - P5
Tags: database
Published: 2023-07-18 04:21:33

### Distributed database copyright installation

#### Distributed database without license file

The trial license file is created during MGR installation: adb\_license\_trail, the data in the file is the encrypted expiration period, and the expiration period is the current time + 30 days. The trial license file will be copied to the backup library during the pg\_basebackup.

MGR adds nodes, and after node initialization, the master node in the cluster generates the trial license file by itself when it initializes.

#### Distributed database with license file

Users need to go to the company's GTM platform to apply for the database license and get the license file.

Place the license file into the data directory of the MGR master and backup, then connect to the MGR master and backup respectively, switch to sql mode, execute activate antdb\_license to activate the license of the MGR master and backup, and if there is a sub-center, also place the license file into the MGR of the sub-center and execute the activation command.

In the MGR node, execute the MGR command activate antdb\_license all to distribute the license files in the MGR data directory to the data directories of the cluster GC master, CN master, and DN master (including the primary and secondary centers), and activate the licenses of the cluster GC master, CN master, and DN master.

Activate by activate command:

```
activate antdb_license all;     #Activate the license file in the data directory of the mgr.
activate antdb_license XXX;     #Activate the license file for a node
activate antdb_license XXX,XXX,…; #Activating license file for certain nodes
```

Append DN/CN master node by APPEND command (except APPEND CN master FOR method), after initdb, send the official license file in MGR data directory to the appended node, and finally start the node to make the license effective.

Distributed cluster append backup node, append CN master node by APPEND CN master FOR, add sub-center, and expand capacity are all backed up to the node by pg\_basebackup. pg\_basebackup will back up the license file in the data directory.

#### License Information Viewing

License information can be viewed with the show command. Since the init time of each node is different, the license information of the trial version of each node is different, so it will be shown one by one when you show.

If you have applied for a commercial license file, after activating antdb\_license all, the license information of each node will be the same, and the show will show one piece of information.

```
show antdb_license all;        #View license information for all nodes
show antdb_license XXX,XXX,…;    #View license information for certain nodes
```

#### License expiration

After the license expires, it does not affect the use of the whole cluster. After replacing the latest license file, you can use it normally after activation.
