10 Nifty Browser APIs

The hosts of the Syntax podcast, Scott Talensky and Wes Bos, shared their experiences of recent life events while discussing ten nifty browser APIs. Wes expressed his excitement over finally owning a dishwasher after hand washing dishes for months, while Scott shared his accomplishment of safely cutting down a tree that was growing dangerously close to power lines. Throughout the episode, they were sponsored by Prismic, LogRocket, and FreshBooks. The discussion then shifted to the topic of browser APIs, which are capabilities that allow developers to access features of the web browser without the need for additional plugins. These APIs can make web development more efficient and add unique functionalities to websites. Despite starting the podcast without discussing olive oil, as a listener had mentioned, the hosts still managed to incorporate it into the conversation, with Wes sharing his recent outdoor projects. Overall, the podcast episode showcased the hosts' relatable experiences and their expertise in web development.

The Get User Media API and the File System API are powerful browser technologies that offer developers unique capabilities to build innovative web applications. The Get User Media API allows access to user devices such as webcams and microphones, enabling fun projects and practical applications like building a Zoom competitor or applying effects to webcam feeds. The File System API, on the other hand, grants access to read, write, and modify files and directories, making it possible to build local file editors, SVG editors, and more, all without requiring users to download new files or zip folders. These APIs expand the possibilities for web development and invite creators to explore new, engaging projects beyond the typical practical applications.

The File System API is a powerful tool for reading and writing files directly from a user's file system using JavaScript, particularly in Chromium-based browsers. It allows developers to create file editors, explorers, and other applications that can interact with the file system in a user-friendly way. The process involves using a file picker function to access the file or directory handle, which can then be used to read, modify, and save files. However, it's important to note that this API has limited compatibility, being only supported in Chromium-based browsers and with some limitations in Safari. Additionally, the security implications of granting websites access to a user's file system are significant, which is why it's mostly used in sandboxed environments like Electron apps. Geolocation API, another long-standing HTML5 browser API, allows developers to access a user's geographic location using latitude and longitude coordinates. It's widely supported across various browsers and can be used to build location-based applications and services.

While automatically obtaining user location data can be convenient for websites, asking for permission to access it right away can be intrusive and uncomfortable for users. Instead, websites should only ask for location data when necessary, such as when a user is looking for a nearby store. Additionally, the use of a headless CMS like Prismic can make website creation and growth more efficient by allowing users to assemble pages using reusable data components called slices. However, the permissions API, which is used to check if a website has permission to access certain features like notifications or the clipboard, has limited support and can be inconsistently implemented across different browsers. Therefore, it's important for developers to consider the user experience and the limitations of various APIs when designing and building websites.

The Permissions API in web development offers a way to request user permissions for various features directly from JavaScript in the browser. However, support for this API is not consistent across all browsers, and if a user denies a permission request, there is usually no programmatic way to change that decision. This can lead to frustration for both developers and users, especially on mobile devices where users only have one chance to grant access to a specific feature. Despite the limitations, the Permissions API is an important tool for web developers, and its widespread support in Chrome and Android is a step in the right direction. However, the lack of consistent support in other browsers like Firefox and Safari can make development more challenging. It's important for developers to be aware of these limitations and plan accordingly when using the Permissions API.

The Web Animations API is a JavaScript method for constructing animations without delving into CSS animations or transitions. It offers the ability to play, pause, reverse, update, and control playback rates. However, it can be cumbersome to use directly and doesn't have the capabilities of more advanced libraries like Framer Motion or Svelte animation. The Resize Observer API, on the other hand, is a favorite for monitoring changes in an element's width or height, as well as its position on the browser window. It's a powerful tool for creating responsive designs and can be used on personal websites, like in the speaker's own experience. Overall, while both APIs have their unique strengths and limitations, they provide valuable solutions for creating dynamic and interactive web experiences.

The Resize Observer API is a powerful tool for developers to react to changes in the size of elements on a webpage in real-time. Previously, developers had to use workarounds like media queries or checking for window resizes to achieve similar functionality. However, the Resize Observer API allows for more precise and efficient handling of element dimensions. For instance, it can be used to adjust the size of a video player when the list of videos next to it is resized. The implementation is straightforward, with minimal code required. While there are performance considerations, the benefits of using Resize Observer outweigh the potential drawbacks. Another mention was the Container Queries API, which is similar to Resize Observer but focused on the container element rather than the child element. Both APIs can be used for various purposes, such as checking if an element is on the screen or triggering actions based on element dimensions. The discussion also touched on the importance of error handling when working with new APIs. LogRocket was suggested as a helpful tool for debugging issues and understanding user experience, especially when dealing with browser errors or unsupported features. Lastly, the Clipboard API was introduced as a simple yet powerful tool for copying and pasting text and images. It's widely supported in modern browsers and can be used for various use cases, such as implementing a copy-to-clipboard button or creating a rich text editor.

The Navigator Clipboard API and Web Storage API are powerful tools for web developers, allowing them to read and write text to the clipboard and store data locally or sessionally, respectively. The Clipboard API, with functions like `navigator.clipboard.readText()` and `navigator.clipboard.writeText()`, enables programmatic copying and pasting of text with user permission. The Web Storage API, consisting of local and session storage, offers a key-value store for text data, with local storage retaining data even after the browser or tab is closed. The session storage, on the other hand, is temporary and gets deleted when the tab or browser session ends. These APIs can be used for various purposes, such as creating a coupon dashboard with programmatically copying coupon codes, or implementing a paste function with permission prompts. While the Clipboard API can read text from the clipboard, it cannot determine if there is something specific in it without further processing. The Web Storage API, being a text-only storage, requires JSON encoding for storing non-text data. Overall, these APIs add significant functionality to web development, enhancing user experience and enabling new features.

Web technologies continue to evolve and offer new functionalities that can enhance user experiences. During this discussion, we touched on a few such technologies, including wipe sequences, session storage, web storage, and speech synthesis. Firstly, not all libraries support wipe sequences, which can be useful for clearing a video or canvas element. This is a good use case for ensuring consistency across different libraries. Secondly, session storage is a topic of debate, as some may find it frustrating when websites do not allow opening a new tab while logged in. However, web storage offers a solution as a local database for storing data, which can be particularly useful for maintaining form data. Thirdly, FreshBooks was introduced as a sponsor and discussed as a cloud accounting solution for businesses, offering features such as invoicing, expense tracking, and tax remittance. Fourthly, speech synthesis, or text-to-speech, was highlighted as an easy-to-use browser API that can be employed for various purposes, such as creating a dance app that shouts dance moves or enhancing accessibility for users with visual impairments. Overall, these technologies demonstrate the ongoing advancements in web development and the opportunities they present for creating innovative and user-friendly applications.

The Web Speech API offers two powerful functionalities: speech synthesis (text-to-speech) and speech recognition (speech-to-text). These features can significantly enhance user experience and engagement in web applications. Text-to-speech, also known as Voice Synthesis, is supported in various browsers except for Opera Android, WebView Android, and Internet Explorer. It allows developers to create voice-enabled applications, where users can interact with the system using simple text input. The API supports multiple voices, pitches, and tones, making the experience more personalized and fun. On the other hand, speech recognition, also known as Speech-to-Text, is the opposite of text-to-speech. It converts spoken words into text, enabling users to interact with applications using their voice. This feature is supported in popular browsers like Chrome, Edge, and Safari. Developers can set up grammars, languages, and continuous recognition, making the user experience more seamless and intuitive. Both functionalities have various applications, from simple games to more complex applications like voice assistants and accessibility tools. By leveraging these features, developers can create more engaging and inclusive web experiences for users.

Exploring various APIs can be an enriching experience, especially when attempting to build examples in each one. While many APIs require a local server and SSL certificate for functioning, they will not work on HTTP. Old media formats like VHS and mini DV tapes can be digitized using affordable devices like the $15 RCA-to-HDMI converter, which has saved the speaker from the hassle of dealing with outdated technology like FireWire. However, some apps and devices may have copy protection that prevents HDMI output, making the official Apple adapter a necessary investment for such tasks. Overall, delving into different APIs and utilizing the right tools can lead to exciting discoveries and the preservation of cherished media.

Technology can be unpredictable and frustrating at times. The speaker shared an experience of dealing with inconsistent HDMI inputs for projectors, where some would work and others wouldn't. This issue was so pervasive that they had to go through multiple units to find one that worked. The speaker also talked about their experience with LED pot lights, which they found to be a simple and cost-effective solution for brightening up spaces. Despite the benefits, technology can still present challenges, as seen with the inconsistent HDMI inputs, but finding reliable and cost-effective solutions can make all the difference. The speaker's experience with both the frustrating and effective uses of technology highlights the importance of perseverance and adaptability when dealing with technological issues.

Home automation and technology integration can present challenges but with creativity and problem-solving, these issues can be overcome. During the discussion, the speaker shared their experience with buying a 100-watt incandescent bulb for an old Easy Bake Oven, expressing surprise at the difficulty in finding such bulbs due to energy efficiency regulations. They also mentioned their desire to automate turning on a red Philips Hue light bulb outside their recording room when they hit the record button. However, they encountered difficulties in connecting the bulb to a hardware button. The speaker suggested a workaround by using their computer's do-not-disturb mode to trigger the light bulb. They proposed writing a function that constantly checks if the computer is in do-not-disturb mode and pings the Philips Hue API to turn on the light. This passive approach would eliminate the need to manually turn on the light. The speaker also expressed interest in setting up a sign for their recording room and discussed wiring options for their new office. This conversation highlights the potential challenges and rewards of home automation and technology integration. While there may be gaps and limitations, creative problem-solving and collaboration can lead to innovative solutions. The speaker's experience demonstrates the importance of finding alternative methods when faced with obstacles and the potential for improving workflows and enhancing the recording experience.

For setting up monitors or microphones in a professional way, running XLR cables through walls is an effective solution. This is commonly done in recording studios by installing XLR outlets on the walls. This allows for hanging microphones from the ceiling or having monitors in separate rooms. However, this method can be costly and complex. An alternative, as discussed by Linus Tech Tips, is using Thunderbolt cables to connect a server or computer to a monitor. But this method may not be as reliable or cost-effective as running XLR cables through walls. It's important to weigh the benefits and costs before deciding on a setup.
