The Web Locks API is a new addition to the Web Platform which allows you to execute JavaScript in a lock, a resource which can potentially get shared with other browser tabs. This API is currently available in Chrome and other Chromium-based browsers with no major signals from other browser vendors.

We usually take for granted how efficiently maps convey information like proximity, spatial relations, distance, and geographical context in a compact visual manner across two dimensions. Attempting to translate that to a non-visual medium and navigate interactive elements linearly by keyboard quickly pulls back the curtain on that illusionary ease.

At this months’s FullStack London 2018, SitePen Engineer James Milner presented the talk “Improving User Experience With Web Workers”. Web browsers use single-threaded JavaScript to perform tasks; business logic, layout, reflows, and garbage collection. This means complex and heavy JavaScript functions can block the main thread from rendering.

At this month’s FullStack London 2018, our CEO, Dylan Schiemann, presented the talk “Choosing a Framework”, based on our Choosing a Framework blog series. Given our long history in web development, we’ve seen JavaScript evolve from an obscure simplistic scripting language to the language of the internet.

For many front-end developers, components have become a central concept in their development workflow. Components provide a robust model for architecting and scaling complex applications, allowing for composition from smaller and simpler encapsulated parts.

Resize Observer allows developers to receive notifications when the size of an element’s content rectangle changes. This helps manage a variety of application layout scenarios including responsive application layout, flexible layouts such as split panes, or dynamic changes in content within an element in a page.

Nest is a scalable framework for building server-side applications. It is authored in TypeScript and relies on the Express framework. It leans heavily on modern language features such as async/await and decorators to reduce cruft and place the focus cleanly on route-handling business logic.

At the recent TSConf, SitePen engineer Sarah Higley delivered a talk titled Escape the Office: Designing Interfaces for Other Developers. The moment you step into any large project or open source venture you must accept that code you write gets used in ways you did not originally intend.

Picture lots and lots of dogs wearing vests Now, are you thinking of a Lewis Carroll-esque canine tea party, or a collection of service dogs? If the latter, you may be ready to attend the thankfully-abbreviated California State University: Northridge Assistive Technology Conference (hereafter referred to as CSUN or #CSUNATC18).

At the recent NEJSConf, SitePen engineer Sarah Higley delivered a talk titled Don’t forget your keys. People tend to assume everyone navigates the world in the same way they do: on two legs, responding to visual cues, hearing speech, reading emotion. For developers, this often means web accessibility comes as an afterthought, if at all.

WebAssembly is an emerging standard for a low-level assembly-like language in a compact binary format that runs with near-native performance, and is available as a compilation target for a variety of languages. We’ve heard significant misunderstanding around WebAssembly and what it means for the web and JavaScript.

In case you missed it, SitePen was the presenting sponsor of the inaugural TSConf which took place in Seattle on March 12, 2018! The Backstory In 2017, we met the TypeScript team in person after years of being avid members and contributors to the TypeScript project.

Intern Recorder is a Chrome extension that can kickstart the process of creating functional tests for Intern. It was initially released in 2015 users of Intern authored test suites as AMD modules.

We have somehow reached a point in time where the integration of life in digital and physical spaces has spawned scores of scholarly articles with titles like “The emerging online life of the digital native.” In a practical sense, it has become increasingly difficult to participate in society without using the internet in some form.

Intern is a popular JavaScript testing framework with an extensive feature set. While Intern has traditionally been focused on testing applications written in standard JavaScript, it has also had great support for TypeScript. With version 4, Intern has been completely rewritten in TypeScript, allowing it to provide a more seamless testing experience for TypeScript projects.

It has come time to read the liner notes and write some conclusions. When we started writing this blog series, we knew that JavaScript/web application frameworks were not easy to summarize.

Not long ago, good design was considered nice to have, but non-essential to a product or company. In today’s market, however, good design has become a commodity. The apps we use on our phones, our laptops, or even on our TVs are constantly scrutinized based on their quality of user experience design.

Intern is complete JavaScript test stack, with support for the entire testing lifecycle. Intern 4 keeps many of the internals of Intern 3, but updates the external interface and usage model to better fit into modern workflows. Why Intern Intern’s goal is to simplify the process of writing complete, high quality application test suites.

TypeScript 2.6 was released on the 31st of October. It is a moderately sized release like many of the other of the more rapid releases from the TypeScript team over the past year. TypeScript 2.6 include a few key and interesting features.

Whenever you start working with a new programming language or framework, you need to learn a new collection of error messages and how to resolve them. Sometimes those messages are obvious, and others only become obvious as you gain experience with the new technology.
