What Is a Web Viewer? Complete Guide

A web viewer is a program that displays webpages directly in a FileMaker Pro layout. This tool can also generate an HTML link based on data in the database table. For example, it can create a map based on the location of a current record. This allows FileMaker Pro to use a variety of templated data-driven websites. To use this tool, you should have a FileMaker Pro website, and then use the built-in WebView2 template.

A web viewer can be placed in a portal or placed within one. If you place a web viewer in a portal, the contents will be displayed as if the viewer were a portal itself. A web viewer may not display properly in the Browse, Find, or Preview modes of a browser. Therefore, it is important to know what type of web viewer you’re using. Fortunately, most web viewers work well in all three modes.

Understanding Web Viewers

In the modern digital landscape, where the consumption of online content has become an integral part of our daily lives, the term “web viewer” has gained prominence. A web viewer can be thought of as a specialized tool or application designed to display and interact with specific types of content within a web-based environment. Unlike traditional web browsers that provide a more generalized browsing experience, web viewers are tailored to offer optimized interactions for specific types of content, making them a versatile and essential component of various online activities.

Defining Web Viewers

A web viewer is essentially a software component that enables users to access and engage with content such as documents, images, videos, 3D models, maps, and more, directly within a web page or application. These viewers are developed to streamline the process of presenting content in a structured and user-friendly manner, ensuring that users can interact with the content without the need to leave the current environment.

Distinguishing Web Viewers from Web Browsers

It’s important to note that while web viewers and web browsers share some similarities, they serve different purposes. Web browsers are versatile tools that allow users to access a wide range of websites and online resources, supporting general web navigation. On the other hand, web viewers are specialized components integrated into web pages or applications to provide a focused and optimized experience for consuming specific types of content. This specialization enhances user engagement by removing the distractions that can come with a full web browsing experience.

How Web Viewers Work

Web viewers are powered by a combination of web technologies that enable the seamless display and interaction with specific types of content within a web-based environment. Understanding how web viewers work involves delving into the underlying technologies that make their functionality possible:

1. HTML (Hypertext Markup Language): HTML forms the structural foundation of web viewers. It provides the framework for defining the layout, content structure, and placement of interactive elements within a web page. For instance, a document web viewer uses HTML to arrange pages and text, while a 3D model viewer uses it to render the necessary components.

2. CSS (Cascading Style Sheets): CSS is responsible for styling and formatting the content displayed within web viewers. It controls aspects such as font styles, colors, spacing, and layout. By applying CSS, web viewers ensure a consistent and visually appealing presentation of content across different devices and screen sizes.

3. JavaScript: JavaScript, a powerful scripting language, is the driving force behind interactivity within web viewers. It enables dynamic features like zooming, panning, rotation, and other user interactions. JavaScript also facilitates communication between the web viewer and the underlying web page, allowing for real-time updates and responsiveness.

4. Integration with External Libraries and APIs: Web viewers often rely on external libraries and APIs (Application Programming Interfaces) to enhance their functionality. For instance, a document web viewer might use a PDF rendering library to display PDF files accurately, while a map viewer could utilize mapping APIs to provide geolocation features. These libraries and APIs streamline the development process and ensure a more robust user experience.

5. Loading and Rendering Content: When a web viewer is embedded within a web page, it loads the specific content it is designed to display. For example, a document viewer would load a PDF file, while an image viewer would load images. The viewer then uses the HTML, CSS, and JavaScript components to render the content within its designated area on the web page.

6. User Interactions: User interactions, facilitated by JavaScript, play a central role in how web viewers work. Depending on the type of content, users can zoom in and out, navigate through pages or images, rotate 3D models, or interact with maps. These interactions enhance the user experience, making the content more engaging and accessible.

7. Cross-Browser Compatibility: Web viewers strive for cross-browser compatibility, ensuring that they work consistently across various web browsers such as Chrome, Firefox, Safari, and Edge. This is achieved by adhering to web standards, testing, and addressing browser-specific quirks and behaviors.

8. Responsiveness and Adaptability: Modern web viewers are designed to be responsive, adapting to different screen sizes and devices. This is crucial to provide a seamless experience whether users are accessing the content on a desktop computer, tablet, or smartphone.
