- Efficient data management and faster performance. Web page content updates are only written when necessary. The virtual Document Object Model (DOM) will manage rendered contents and actual DOM only used when there is content change.
- Data inside the site’s markup is well formatted and easily understandable.
- Contents are displayed based on the components.
Server Load Time
Comparison: React vs. Vue vs. Angular
Advantages of React
React is using simple abstractions and has conceptual integrity which makes react favourite for developers. They have their own template engine to start working with; React is also equipped with paradigm component and event model so that it’s more manageable for developers.
Disadvantages of React
Advantages of Angular
AngularJS manages its own binding and does not require developer to step in at all.it ensures that all changes made are getting updated instantly in the model without delays. Since angular supports caching, it reduces effort from application server so that server resources can be efficiently utilized for other important tasks. Also, it is extremely easy to develop app prototypes of good quality with very less coding. Other major interesting aspect is the use of plain HTML templates which is helping the developers to reuse the templates more efficiently.
Disadvantages of Angular
Advantages of Vue
With VueJS, you can build your application functionality in number of ways, which make it a favorite for developers. Vue uses a single file component and it overrides all HTML attributes, purpose, semantics, etc. It also allows its components to communicate with each other, which is a key factor of this framework. Major companies like Netflix, Adobe and Xiaomi are using Vue.
Disadvantages of Vue
Since the release of the first version, there has been major issues are with the stability of the framework. Vue cannot be used for larger projects where stability and security is very important, as it can cause larger impact to the organization.
Side by Side Comparison: ReactJS, VueJS, and AngularJS
The image below shows the basic differences between frameworks, along with performance criteria.
React vs. Vue vs. Angular: Additional Considerations
Angular and React are more stable compare to Vue. Vue has lot of issues with high technology-based applications.
Angular is compatible with DOM library and frameworks. Also, it includes a lot of support libraries. Vue has much less third-party library support.
Learning curve of Vue.js is good compare to React, as it has used a smaller number of abstractions. Angular has also comparatively less learning curve.
Angular is the most complex framework, but Vue is easy to set up.
Angular has a wider range of community support than react and Vue. Lots of free tutorials, third-party tools, and libraries are available for Angular and React. Vue is far behind them in terms of community support.
For complex functionality applications, React is the first choice as it is high performing and stable. Even though we can use Vue for small projects, this framework will get unstable with the project size.
React uses a 3-clause BSD license. Vue and Angular require an MIT license.
Vue and Angular are created using MVC architecture which supports two-way data binding. React supports uni-directional flow. Due to the complexity of the mobile development, it is recommended to use React for the better stability.
Optimization Case Study
Performance Benchmarks: Angular vs. Vue vs. React
The image below represents the various performance benchmark aspects, such as interactive time, script boot time, and memory efficiency.
Step 1. Initial Setup and Using The EveryStep Web Recorder
If you don’t have a LoadView account, you can sign up for the free trial. You receive free load tests automatically. If you already have an account, you login in to your account directly, or launch the EveryStep Web Recorder to begin scripting. Or if you’ve logged in to your account, click on New Test and this will open the recorder window as shown below. Select Web Applications.
Step 2. Enter URL and Record a New Script
Once you click on Web Applications, it will start the EveryStep Web Recorder. You need to enter the address of the web application,. In our case, it is histography.io. You can even toggle between Desktop/Mobile based on your requirements. According to your selection, recording mode will be changed. There are different mobile options available such as Android, iPhone, etc. Additionally, there is also an option to toggle between screen orientations which will imitate mobile/screen behavior. Once you’ve entered your requirements, click Record Now.
The recording will be started and you can navigate through the flow which you need to record for your load test. In the script code section, you can see the details of the recording and we can modify the code as needed. You can add specific parameters, such as delays, Crypt variables, network conditions, and more, for your specific requirements.
Step 3. Complete Your Script
Click Stop once you complete the recording. Click Play Now to replay the script. This will ensure there are no error captured during the recording. The script will be replayed with the user paths that you have recorded.
If there are errors in the script, it will show an error message. Otherwise, if there are no errors, it will show the success message below. Save your script and modify later, if necessary.
Recorded script details will show once you click on the Save Script button. This script can be changed for the further enhancement.
- Add a Step. To add additional steps to the end of a script, simply press the record button, and select the option to continue adding steps.
- Modify a Script with Tools. To add a new lines in the middle of a script using the wizard; you can right-click the script within the editing pane (at the bottom of the screen) where you want to add a new line. The context menu with the tools to add as new steps will appear.
- Edit Variables. To edit variables such as keywords, field values like usernames and passwords, do a left-click on the underlined field label to edit the value.
- Context Parameters. It is possible to convert a script method parameter to a context.
For more information about editing a script, please visit our Knowledge Base page.
Step 4. Create Your Device
Click on the Create Device button to begin the test execution steps.
You can make any final changes, if required before proceeding. Click on adjust user behavior or edit device for further changes. Based on the number of users and duration, you can see the total cost for the execution.
Step 5. Create Your Load Test
Choose any load type curve, dependent on your your requirements. LoadView gives you three different choices: Load Step Curve, Goal-based Curve, and Dynamic Adjustable Curve. Based on your specific performance requirements, you can decide your load type. We have chosen the Load Step Curve for this test.
Step 6. Start Your Load Test
Once you have chosen the test type and servers, click Continue. You will be asked you for your email address which is required to notify you once the test is completed. A default test results will be also sent to the owner of the LoadView account. There are two options available for starting the test. You can either start the test now or you can schedule it for later.
Once the test is started, you can see the real-time information about the test status. All the information related to server, as well as scenario details, will be provided. There is also an option to cancel the test if you want to do a last-minute change. Initial status of the test will be submitted, and it will change to running status once the test has started again.
Step 7. Load Test Execution
The work model graph, a.k.a. the execution plan information, will be available under Test Summary tab, this will also give information about the maximum number of users who are running tests. It will also shows the number of actual and expected users.
Total number of success sessions and Total number of Error sessions. This graph will give you information about errors.
Step 8. Performance Test Analysis and Report
Once the test has completed, you will see the load test report, along with execution details, which will provide overall information about the execution. You will also receive a load test report in your email with the details and a PDF attachment. This can be shared with your team members.
The LoadView platform can help you to test your websites and applications for big traffic events, like Black Friday/Cyber Monday. It’s never to early to ensure your e-commerce sites and applications can perform under spikes in traffic.
