Furthermore, the need to reinvent existing browser functionalities like the document object model (DOM) can cause accessibility concerns and negatively impact keyboard input and screen readers, creating further challenges for developers.
When we talk about internal applications, we are referring to web applications developed for usage within an organization. Internal applications have different requirements and development priorities than external-facing applications. Here are some characteristics of internal applications:
Fewer Users: Internal applications have fewer users as compared to external applications, and they are typically used by employees of an organization.
Language Constraints: With internal applications, developers don't have to worry about internationalization as the users typically speak the same language.
Desktop/Laptop-based: Internal applications are primarily used on desktops or laptops, and developers don't have to worry about mobile compatibility.
Security Constraints: For security reasons, some internal applications cannot be accessed from mobile devices, and require fully corporate phones with strict policies and constraints.
Fast Development Cycle: The focus of internal applications is on fast development cycles that allow developers to write and test code quickly in a development environment.
External applications, on the other hand, are web applications that are available to the public or specific user groups outside of an organization. With external applications, developers have to consider a broader range of factors such as scalability, performance, and compatibility across different browsers and devices. Here are some characteristics of external applications:
Large User Base: External applications have a large user base, and developers have to ensure that the application is scalable, secure, and can handle a large volume of traffic.
Internationalization: With external applications, developers have to consider internationalization, as users may speak different languages and have different cultural expectations.
Device Compatibility: External applications need to be compatible with various devices and browsers, including desktop, mobile, and other internet-enabled devices.
Defensive Development: Developers have to consider all kinds of edge cases and users with slower network connections and ensure that the application works seamlessly under different scenarios.
However, it is essential to ensure that all the different components of an application work together seamlessly and accurately. This can be challenging, especially when dealing with browser APIs, where there is no guarantee of consistent outputs. Unfortunately, not knowing the type of data an application is receiving can sometimes lead to bugs that can affect its functionality.
The Journey to Typescript
Moreover, introducing Typescript into an existing project can be done gradually, which means developers can use it creatively for specific cases or file-by-file as they learn to use it correctly. Using "any" for migration is also possible, but only with caution. Its primary usage is for migrations, and developers must avoid using it except when they know what they are doing.
Exploring the Potential of WebAssembly in Web Development
Benefits of Using WebAssembly
- Compatibility: WebAssembly is supported by major browsers which make it a very accessible technology.
- Portability: As WebAssembly is a portable code that can execute in any runtime, it provides the ability to write once and run anywhere.
- Security: WebAssembly provides predictable resource consumption, prevents buffer overflows, and protects against vulnerabilities present in higher-level languages.
Use Cases of WebAssembly
- Video and audio transcoding: With the help of WebAssembly, developers can transcode and compress videos in the browser instead of servers, which are also capable of doing it. This can save server resources and can be done on the client-side in real-time.
- Gaming: WebAssembly can be used by game developers to increase the performance of web-based games. With support from popular engines like Unity and Unreal, WebAssembly provides an alternative to native desktop and mobile game development.
- Simulation: WebAssembly enables developers to run high-performance simulations in the browser, despite being resource-intensive.
- Porting existing codebases: Developers can port existing codebases using C++ into WebAssembly to reuse and enhance existing libraries or functionality for use in browsers.
The Future of WebAssembly
As with any new technology, it is essential to stay up to date with the latest developments in WebAssembly to leverage its full potential. In this article, we have explored some of the opportunities that WebAssembly provides. In subsequent articles, we shall look at various examples of how WebAssembly is being used while providing insights into its benefits and limitations.
