Key Elements to Incorporate in an Electronic Commerce Application

While each shopping solution presents its selling proposal, it exhibits some fundamental characteristics similar to those of other rivals. In the following section, we have compiled the primary characteristics that constitute the bulk of applications within this specific domain. It is also worth considering their inclusion in a Minimum Viable Product (MVP) for the application.
Authentication capabilities
Verifying a user’s identity is a crucial aspect of any eCommerce solution, as it enhances security measures and mitigates the risk of unauthorized access by malicious individuals. Individuals can register for your application using their email address, phone number, or social network credentials.
In addition, implementing two- or multi-factor authentication is a supplementary measure to enhance clients’ security. Both of these techniques need the user to authenticate themselves by logging in using two or more authentication mechanisms, such as a personal identification number (PIN), a one-time password, or a separate device.

Profile of the User

The identification of customers by the program enables company owners to get more information to refine their suggestions and other marketing endeavors. In contrast, customers can input the necessary information on a single occasion and retain the data for subsequent transactions. User profiles can include fundamental user details, such as email addresses, given names and surnames, shipping addresses, and purchase histories, among other relevant information.
Search with specified filters.
The core elements of mCommerce apps revolve around product selection and exploration, emphasizing the search functionality’s criticality. Implementing filtered search functionality enables users to refine their search results, resulting in a more targeted and pertinent array of options that align with their purchase requirements. The “Refine Result” checkboxes should be category-specific and allow updating the available results automatically.
Image search is a frequently employed feature in several prominent apps, such as ASOS, AliExpress, and others.

Shopping carts

The shopping cart pages should effectively enhance customers’ intention to purchase by smoothly directing them toward the order checkout process. Regarding the particular constituents, carts must provide a prompt recapitulation of the product(s) that have been added to the cart, together with their corresponding pricing and pertinent product details. In order to proceed with the transaction, consumers must be provided with the opportunity to choose their desired payment method and specify their preferences for delivery and return arrangements.
Gateways for online payments
Incorporating one or more payment services is crucial in facilitating the transfer of funds from the client to the merchant’s designated bank account. From a technological standpoint, the activation of payment gateways occurs via the integration of application programming interfaces (APIs), which establish a connection between the checkout function of a company and the payment system. PayPal, Amazon Pay, and 2Checkout are among the prominent choices in online payment solutions. The inclusion of debit and credit card payment functionality, together with support for mobile wallets, is recommended for your eCommerce application. Statista identifies these payment methods as the predominant ones in the industry.

Efficient and expedited payment process

This stage concludes the procurement procedure and often involves inputting the delivery address and payment information. Based on the findings reported by Shopify, it has been observed that a notable proportion of consumers, namely 18%, tend to leave their shopping carts as a consequence of encountering a protracted and intricate checkout procedure. Hence, optimizing the efficiency of the checkout process will contribute to client retention.
One of the most often used checkout structures in e-commerce is a one-page checkout, which encompasses the presentation of shipping, invoicing, and order summary information on a single page. The use of a two-step checkout system is prevalent among shops that choose to divide the procedure into two distinct parts.
Push notifications
Push notifications serve as a prominent re-engagement medium for businesses, effectively motivating consumers to participate in purchase activities. Precisely timed and tailored in-application push notifications have the potential to mitigate instances of cart abandonment, provide real-time updates on active promotions, and provide location-specific messaging, among other functionalities.
The real-time nature of the functionality is another compelling reason why your mCommerce app will benefit from its inclusion. Consequently, push alerts are more prone to eliciting an immediate response.

Customer Assistance

The cornerstone of a retailer’s brand reputation is consistently providing outstanding and punctual customer service. Based on research conducted by Hubspot, it has been shown that a significant majority of consumers, namely 93%, exhibit a high likelihood of engaging in repeat transactions with organizations that provide exceptional customer service. The integration of live chat capabilities has gained significant popularity as a software solution, as it facilitates instantaneous customer service, enhancing communication effectiveness and diminishing response durations.
Personalized mobile application dialogues may be expanded via chatbots or conversational artificial intelligence (AI). These advanced technologies facilitate self-service for clients and effectively manage recurrent inquiries. Specific software development kits (SDKs) for live chat, such as Sinch or Twilio, have a chatbot functionality.

Delivery Monitoring

This functionality allows consumers to get information about the current status of their delivery. In the event of a delay in delivery, customers are provided with real-time information about the present status of their package and the underlying cause for the delay.
The eCommerce solution can get real-time shipping data from shipping application programming interfaces (APIs). These features enable the seamless integration of real-time order-tracking functionality into your mobile application. The real-time data obtained from the application programming interface (API) may initiate a notice for the consumer afterward.
Preferred choices of customers
In order to enhance sales, eCommerce solutions include a selection of presently popular daily goods that clients most often purchase. Additionally, this functionality can display a compilation of often-bought items specific to a particular consumer inside their designated user account. The vendor can access a record of previously bought items to give customers customized promotions, discounts, and tailored suggestions.

High-quality product pages with descriptions and photographs

Captivating descriptions accompanied by well-matched visual representations can effectively highlight the items, leading to a positive perception and a higher likelihood of successful conversions. In order to provide comprehensive information to potential customers, product descriptions have to include essential details such as dimensions, color variations, pricing, shipping particulars, customer reviews, and any other pertinent information that may assist consumers in making informed purchasing decisions. The mitigation of consumer complaints and returns may be achieved using precise and comprehensive product descriptions.
The implementation of effective visual merchandising strategies requires the inclusion of high-quality product photos in mCommerce apps. Therefore, consumers anticipate a range of 5 to 8 visual representations of the product.
Product evaluations and rankings
Customer reviews and star ratings are crucial in aiding consumers in product research and facilitating informed purchasing choices. Moreover, they provide a supplementary avenue for merchants to get feedback and mitigate the occurrence of client complaints.

Program of loyalty

Achieving brand loyalty is the ultimate objective for any eCommerce business. Hence, integrating a loyalty program into the customer experience has significant implications for establishing and enhancing brand equity. Based on a survey, a majority of individuals who own loyalty programs, precisely 56.0%, assert that their current rewards program positively impacts sales, yields a favorable return on investment, and enjoys significant popularity within their client base.
From a technical standpoint, two options are available for implementing a loyalty program: integrating an in-house system or outsourcing the process to an external provider. According to the survey, around 49% of loyalty programs are overseen by a vendor specializing in loyalty technology solutions. In comparison, more than 50% of these programs are administered internally by the organization. Ensuring that the loyalty solution has data processing capabilities and is equipped to support future enhancements is essential.

1. Learning version control
   Learning version control is something we should all be familiar with nowadays. Whether you’re applying for a job at a company that uses one of the three big ones (GitHub, BitBucket, GitLab) or TFVC and SVN, at some point you’ll be required to have some familiarity with version control and remote repositories.

The Academy does not teach version control, at least not the schools I know. No student I’ve ever talked to has ever said: “we learned about version control” or “version control is part of the curriculum”. This is a huge problem for academia, to confront this by learning it yourself.

2. Storage.
   When I started building websites/pages, I had no idea what version control was. I was distracted. Version control for me was saving files over and over again with different names like index.html, index1.html, index2.html and putting them on 3.5-inch floppy disks. It was an old-school version of source control.

The ability to store your code in a remote repository is great, especially if you need to go back and make changes, copy it for use elsewhere, or restore it if your local files are corrupted.

3. A building block
There are many companies today that won’t hire you without some type of online code presence, it’s unfortunate but true. Whether it’s a portfolio or a repo on GitHub where they can see the quality of your code.

Your code may not be the best in the world, but at least it shows that you are putting your code out there for others to see, and that’s the hardest step in overcoming imposter syndrome when it comes to code quality.

4. Frame of reference
I was skeptical about using GitHub for personal code and projects until Detroit Labs co-founder Nathan Hughes told me during a workshop that it was very valuable, and they were right. I started using GitHub in 2014, my first commit was on April 10, 2014, and my first fork was on June 25, 2014.

I’m not saying that the quality of my code was bad, but it’s amazing to see where I was and where I’ve come. Branching out repositories and adding small code snippets to branching out large open source projects and creating my own open source projects. It’s always great to see your accomplishments, remote code repositories are perfect for that.

I hope this helps you determine how you are going to store and preserve code in the real world. Trust me though, it will definitely pay off in the end.

The post Four advantages of using a remote code repository appeared first on Lib Sjava.

One of the main advantages of a remote repository is that it facilitates collaboration. Several developers can clone the same remote repository, each with their own local copy, and contribute to the project at the same time. The remote repository acts as a central synchronization point, allowing team members to merge their changes and resolve conflicts if necessary.

Working with a remote repository also improves project visibility and provides a backup of the code base. With a remote repository hosted on platforms like GitHub, developers can showcase their work, collaborate with others through pull requests, and use additional features like issue tracking, code reviews, and continuous integration.

In addition, the remote repository ensures the security and availability of project code. In the event of a local machine failure or loss, developers can easily resume their work by cloning the remote repository to a new machine. This redundancy and backup mechanism is crucial for maintaining project continuity and protecting against data loss.

Working with Git involves managing both local and remote repositories. Local repositories offer the benefits of offline access, speed, and flexibility for experimentation, while remote repositories provide collaboration, backup, and project visibility. By using the appropriate Git commands, developers can work with both types of repositories seamlessly. Whether it’s initializing a local repository, making changes, or pushing to a remote repository, Git provides a complete set of commands to optimize your version control workflow.

The post The main advantages of a remote repository appeared first on Lib Sjava.

If we connect the remote repository to our local repository, we will have copies of all the reference objects in the remote repository. That is, for example, the remote repository has a main branch, and we will have a copy of this branch – origin/main. All such reference objects (pointers, branches and tags) of the remote repository are stored almost in the same place as the local one – in the directory .git/refs/remotes/.

It is common to name remote branches (that is, branches of remote repositories) by appending the name of the remote repository to their name. For example, if we have a remote repository with the name origin and the branch main, we would call that branch origin/main. We will do the same with all other reference objects. This may seem redundant, but it actually adds definition and prevents you from getting confused by multiple branch names.

One of the advantages of a distributed version control system is that you can have as many remote repositories as you want. Some of them can be read-only, and some of them can be read-write.

Thus, to become a full-fledged Git user, it is important to learn the skills needed to work with a remote repository. These include creating new and copying existing remote repositories to yourself, uploading local commits to the server, and downloading changes from the server.

With these features, you can get the following benefits:

• You can easily get started on a new project or module without wasting time.
• It makes your builds consistent throughout the process.
• You can easily work on multiple projects at the same time.
• Maven allows you to save JAR files for future use.
• This improves communication between different projects and solves backward compatibility issues.

Project management
Maven creates Java projects from its templates. It then creates a project directory. Your source code will be placed in a folder in this directory. Maven creates a pom.xml file for your project. It then manages the details of your project in the form of Project Reports and Project Information. Using the project object model, it stores all of your project metadata in a central repository.

Build automation
Maven starts automation by loading dependencies. Later, it manages source code compilation, binaries, packaging, test execution, and reporting. This disciplined way ensures optimized automation. This allows you to release your product after repeated testing and modification.

Dependency management
Managing the versioning of dependencies for a large project is difficult. But Maven helps you manage and standardize the versioning for everyone on your team. Thus, it provides a built-in structure for writing your code. If you want to change the version of a dependency, you can do so by updating the version in the XML file.

Continuous integration and deployment
The best results are achieved when you choose Maven Jenkins or Maven Travis CI. Maven is a build tool, while Jenkins and Travis CI are integration tools. These integration tools control every segment of the CI/CD pipeline and offer successful DevOps for your Maven projects.

The post Key features and benefits of using Maven appeared first on Lib Sjava.

The bad thing is that all other project members must do the same on their local machines. Even if you want to maintain your project on another physical machine, you have to install it there again. This means that you have to somehow keep a list of all the jar files that need to be installed before initializing the project, and if some jar is updated to a newer version or some other jar files are included in the project, you have to notify all the participants.

This solution is suitable when you are working on a project alone and using only one machine. When more people start collaborating on the same project, or when you need your project to be easily portable, this is not recommended.

Using system dependencies

Another simple but not recommended solution is to use jar as a system dependency. With this solution, you don’t need to install anything. You simply add your jar to the project, specifying its system path. Since the system path can be relative to the project directory, it does not need to be changed for each project member.

The post Installing the jar locally on your machine appeared first on Lib Sjava.

Build tool

Maven is a build tool, like ANT, that is used to create JAR, WAR, and EAR files in the Java environment. Although there are many differences between ANT and Maven, the later versions are very easy to use because of the minimal configuration.

Dependency management

The main advantage of using Maven to build a Java application is dependency management. Since a Java application depends on many internal and external open source libraries with different versions, it is advisable to have an internal maven repository to archive all versioned JAR files of both internal and external libraries and allow each application developer to automatically import them using Maven when building the application. Maven itself maintains libraries known as the maven global repository with a URL.

Transient dependencies

Maven also manages transitive dependencies for you. This means that when you include the Spring framework as a dependency in your project, you don’t have to download all the libraries that Spring depends on.

Setting up Maven

To use Maven, you need to install Apache Maven in your computer’s configure settings.xml file, which contains the name of your local repository and connection details for connecting to the global maven repository. Please follow the steps in this guide to install Maven on your Windows 8 machine.

M2Eclipse plugin

If you are using the Eclipse IDE for Java development, you can also use the M2Eclipse Maven plug-in, which gives you the ability to create, modify, and run maven projects from within Eclipse. The M2E Eclipse plug-in can be downloaded and installed from the Eclipse Marketplace.

Pom.xml

Another important thing in Maven is the pom.xml, it is similar to the build.xml of the ANT build tool and for each project you have your own pom.xml which stands for the object model of the project. This pom.xml contains project details like artifactId, groupId, name, etc. that are used to create the output, like a JAR file, and can be used to upload the JAR to the internal maven repository. More Java HashSet examples

Tasks vs. goals

You can create and run a Maven project either from the command line or from within Eclipse itself. Just like a task, Maven has goals, and you can run these goals by invoking them with the mvn command on the command line.

Configuration convention

Once you have installed and configured Maven on your local machine, you can create Maven projects. A Maven project provides a standard directory structure for organizing source, resource, and test classes. They follow a configuration convention, which means that all Java classes will go into the src/main/java folder and all test classes will go into the src/main/test folder.

Target directory

When you create a project with Maven, it creates class files and copies the resource to a target directory. You can find all your class files in the target/classes directory. When you run the maven clean command, it cleans up this directory to recompile your Java files and create new class files.

Gradle is not an invention for Android Studio, the system has been developed before and used in applications for Java, Scala and other languages.

The Gradle build system is very powerful and complex to talk about in a nutshell. There are whole books about it. The commands themselves in Gradle are plain text using Groove syntax for configuration. But we don’t need to know everything. Let’s get to know the system and learn how to use it.

Create a new project or open any existing project from Android Studio and look at the project structure.

In the latest versions of Studio, Gradle files have been separated into a separate folder Gradle Script. Expand it. You should mainly be interested in the build.gradle file, which refers to the module. Next to this file, it will say Module: app in brackets. Double click to open it, you will see that the file is a text file.

There is also a build.gradle file that refers to a project. But it is less often worked with. This is where the settings for repositories and Gradle itself are located.

Back to the module file, you will see a lot of interesting information. For example, you can see there the settings that you could previously see in the manifest – version numbers, SDK numbers, and so on. Looking ahead, I will say that you can add just one magic line here and the required library will be downloaded from the Internet and installed in the project. Beautiful!

But let’s return to the root folder. Besides build.gradle files, we can notice gradle.properties, settings.gradle and other files. There is no need to touch them.

The root folder also contains gradlew and gradlew.bat files for working with Gradle Wrapper. In principle you don’t need to know anything about them. But for the paranoid, here’s some information – if you often import projects from unknown sources, they contain a file gradle/wrapper/gradle-wrapper.properties. Open it with a text editor and look at the distributionUrl address. The path should lead to the official //services.gradle.org site or to an internal corporate server. Other addresses should raise an alarm.

You may have noticed that the file structure has changed compared to Eclipse. The app folder contains the src folder and the main folder, which contain the java, res and manifest file folders. The new structure better meets Gradle’s requirements for file management.
