5 challenges in Web Application Development

Web applications are everywhere on the internet! Every time you send a mail, do online shopping, or browse your social media accounts, you are using a web application. They usually work on all the browsers and can be easily accessed on mobile and tablet computers, while providing a seamless experience as the native application.

Web application development involves client-side and server-side programming to develop an application accessible over a web browser. We have identified 5 problem areas that you would need to address to build a successful and high-performing web application.

Speed and Performance

Getting a user on a website is a big challenge in itself. You wouldn’t want to increase the bounce rate just because your web application did not load in time. Un-optimized database, unexpected traffic spikes, troublesome third-party integrations, poorly written code are all recipes for slow websites.

Deploying CDN (content distribution network) to ensure that the server requests get balanced in one good solution. Also, make it a point that your developers should be aware of the amount of media on the webpages, any plugins, configurations, etc in the planning stage itself. This way they can make provisions from the beginning instead of optimizing codes till the last minute.

UI/UX

A good chunk of your users will be visiting your websites via smartphones. The UI must be simple, intuitive, and accessible. This includes:

  • Predictable navigation
  • Clear and simple copy
  • Engaging visuals
  • Easy to understand typography

Make sure that designers don’t get carried away with the aesthetic aspects that they miss out on the usability, accessibility, and intuitive factors. The end goal is to give users an experience that will increase your recall value and make them visit your website again and again.

Security Threats

Web security is a vital task that needs to be done right. SSL encryption is one such standard practice that enables encrypted communication between web browsers and servers. The most common threats are:

  • Cross-site scripting
  • Cross-Site Request Forgery
  • SQL Injection
  • Phishing
  • Shell Injection
  • Buffer Overflow
  • Session hijacking

Developers should implement the security measures right from the start and keep updating as your application grows. Your user data needs to be protected at all costs, as even a small vulnerability can be exploited by hackers in any way. Thus, the right coding with encryption should be done to protect you and your website from cyberattacks.

Tech stack

Your tech sack should include the right combination of servers, frameworks, programming language, and tools. The right tech stack will do wonders for your present and plans. Your project size, its anticipated growth, your team’s expertise, competitors’ tech stack, etc. will help you decide upon your tech stack.

You can also look for tools and software that have a huge community so that any queries that your teams may have are resolved quickly. Look for the documentation available as well so that it becomes easier for your team to have reliable information at their disposal.

Scalability

Scalability is essentially believed to be about load balancing between servers at peak traffic times. You need to consider the following points:

  • Develop software that runs smoothly on clusters of servers
  • Implementing cloud computing from a future point of view
  • Implementing Service orientation architecture (SOA)

Keeping your website future proof ensures that as you grow, your website does as well without troubling your users. This again needs to be considered from the start and assessed as to your customer base increases.

Working on creating the best web app for you and your users can be a daunting task but you don’t have to shoulder the burden all by yourself.

10 VS Code Shortcuts To Code Faster In 2021

VS Code is loaded with lots of features by default that makes it powerful, even without the themes and extensions.

However, even experienced developers may not be aware of these useful features. Not everyone has the time to explore every tip and trick to find the ones that help them code faster. With each new update of VS Code, new features are introduced that often remain unexplored.

Here we’ve listed the 10 most useful VS Code tricks that can help you code faster this year.

1. Multi cursor selection

Defining multiple cursors helps in editing a document in more places simultaneously. Multi-cursor mode can be used for column-mode editing. You can place as many cursors in as many places as you want in a single editor view. You can continue editing once you have your cursors placed, and all operations will be implemented to all cursors at the same time.

To set cursors above or below the current position use Ctrl+Alt+Up or Ctrl+Alt+Down. To add cursors at arbitrary positions, select a position with your mouse and use Alt+Click. You can add additional cursors to all events of the current selection with Ctrl+Shift+L. To go back to a single cursor, just hit the Escape key.

2. Open/Close terminal with one hand

It is convenient to have a pop-open terminal window in VS Code. No need to switch out to another application window to deal with the terminal. It’s also readily accessible by pressing Ctrl + (the backtick key).

What’s nice about this feature is that the shortcut is a one-hand operation, so you can open or shut the window without touching the mouse.

3. Type to find any command

From Command Palette, you have access to all of the functionality of VS Code, including keyboard shortcuts for the most common operations and any registered command, or those provided by add-ons. Press Ctrl-Shift-P and start typing.

Further, if there’s a key binding related to a given command, it’s available in the type-to-search drop-down list. So that you can cut straight to the key shortcut in the future.

4. Open the new editor window to the side

Sometimes we want to open the definition to the side so that we can use “Command + Option + Click.”

5. Github pull requests and issues 

If you are working with Github, you can install Github pull requests and issues extension to search for any project and clone a repository to the editor itself. This saves you time to go directly to github and bring it to your terminal.

6. Source Code Navigation

When we read codes or after reading the definition, we often need to jump from the source code to their definition. Here you can use the following shortcut keys to complete the source code navigation.

Go to Definition: F12

Go back: Control + –

Go Forward: Control + Shift + –

You can also use F12 to continuously jump between different definitions. When you want to go back to continue coding, you can use “ control + -” to go back, but the efficiency of doing so is too low. At this time, you can go back to coding with only one step i.e. by using the command “Go to Last Edit Location.”

7. Grid Editor Layout

Editor groups are placed in vertical columns, by default (for example, when you split an editor to open it to the side). You can easily place editor groups in any layout you like, both vertically and horizontally:

You can create empty editor groups, to support flexible layouts. There are also a predefined set of editor layouts in the new View > Editor Layout menu:

8. Code Folding

Code folding is required when the file size is big and you just want to get an overall understanding of the code.

1. To fold the innermost uncollapsed region at the cursor:

On Mac: Command+ Option + [

On Ubuntu/Windows: Ctrl + Shift + [

2. Unfold will re-open the collapsed region at the cursor:

On Mac: Command+ Option + ]

On Ubuntu/Windows: Ctrl + Shift + ]

9. See Visual Studio Code’s internal process list

Similar to any other task manager in every OS, VS Code has its own internal Process Explorer that lets you see a list of all the current subprocesses running inside the code editor. You can see every externally spawned process, extension, window, and so on. For each process, Process Explorer displays the memory usage, the CPU, and process ID.

Search for “Process Explorer” in the command palette or just select “Open Process Explorer” from the Help menu to open Process Explorer. You can right-click on a process to kill it or copy its information.

10. Remote Development

Since remote development has become the norm for developers, many have started using remote development extension packs. This comes with remote wsl, containers, and ssh, or you can separately search for an extension that lets you work inside the browser, also known as VS Codespaces.

It is split into two components – the UI component which would run on the local machine and another one is the server component, which would let you run, edit and debug your code on the remote machine. The VS Code server can run anywhere, and the remote extension will help you communicate b/w VS Code and the server.

This helps avoid having huge mono repositories, where devs would connect to a huge vm and nothing would be available on their local machine so that they can deploy changes and fixes.

Give It A Shot!

Now that you are armed with the useful productivity tricks, go ahead and give it a try. Once you get the hang of all these shortcuts, you will wonder how you survived without them. You may even blow the minds of some of your Emacs or Vim friends or co-workers with your efficient coding tricks!
