SD Times Open-Source Project of the Week: Lexical

Facebook announced that it open-sourced Lexical, an extensible JavaScript web text-editor library that emphasizes reliability, accessibility and performance.

The project’s set of editor states represent the current and pending states of the editor at any given time. Developers can attach a content-editable DOM element to editor instances, and also register listeners and commands. Users can create an editor instance with the createEditor() API.

Lexical’s states contain two parts: a Lexical node tree and a Lexical selection object which are immutable once created. 

Lexical has its own DOM reconciler that takes a set of Editor States (always the “current” and the “pending”) and applies a “diff” on them. It then uses this diff to update only the parts of the DOM that need changing. 

Lexical is compatible with screen readers and other assistive technologies and it is framework agnostic and provides a set of bindings for React to simplify building custom functionality.

Additional details on Lexical are available here

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice.

Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
