Internal tools are often built with Ruby on Rails or NodeJS. Developers create entire full-fledged applications in order to suit simple needs such as database lookups, dashboarding, and product refunds. This internal tooling creates a drain on engineering resources. Retool is a low-code platform for creating internal tools. These internal tools can be written by The post Retool with David Hsu appe...

For all the advances in software development over the years, one area that has seen minimal improvement is the terminal. Typing commands into a black text interface seems antiquated compared to the dynamic, flashy interfaces available in web browsers and modern desktop applications. Fig is a visual terminal assistant with the goal of changing that. The post Fig: Visual Terminal Assistant with Bren...

Deno is a runtime for JavaScript applications. Deno is written in Rust, which changes the security properties of it. Parts of Deno are also written in TypeScript, which are causing problems in the compilation and organization of Deno. Elio Rivero is an engineer who has studied Deno and TypeScript, and he joins the show to The post Deno and TypeScript with Elio Rivero appeared first on Software Eng...

WebAssembly allows for the execution of languages other than JavaScript in a browser-based environment. But WebAssembly is still not widely used outside of a few particular niches such as Dropbox and Figma. Nicolo Davis works on an application called Boardgame Lab, and he joins the show to explain why WebAssembly can be useful even for The post WebAssembly Migration with Nicolo Davis appeared firs...

Users do not use web applications in the way that you might expect. And it is not easy to get the data that is necessary to get a full picture. But a newer API within browsers does make this more possible by capturing DOM mutations.  The change capture of these DOM mutations can be stored The post Digital Experience Analytics with Michael Morrissey appeared first on Software Engineering Daily .

The modern release workflow involves multiple stakeholders: engineers, management, designers, and product managers. It is a collaborative process that is often held together with brittle workflows. A developer deploys a new build to an ad hoc staging environment and pastes a link to that environment in Slack. Other stakeholders click on that link, then send The post Pull Request Environments with...

Over the last 5 years, web development has matured considerably. React has become a standard for frontend component development. GraphQL has seen massive growth in adoption as a data fetching middleware layer. The hosting platforms have expanded beyond AWS and Heroku, to newer environments like Netlify and Vercel. These changes are collectively known as the The post RedwoodJS with Tom Preston-Wern...

Web development has historically had more work being done on the server than on the client. The observability tooling has reflected this emphasis on the backend. Monitoring tools for log management and backend metrics have existed for decades, helping developers debug their server infrastructure. Today, web frontends have more work to do. Detailed components in The post Frontend Monitoring with Ma...

V8 is the JavaScript engine that runs Chrome. Every popular website makes heavy use of JavaScript, and V8 manages the execution environment of that code. The code that processes in your browser can run faster or slower depending on how “hot” the codepath is. If a certain line of code is executed frequently, that code The post V8 Lite with Ross McIlroy appeared first on Software Engineering Daily .

Programming languages are dynamically typed or statically typed. In a dynamically typed language, the programmer does not need to declare if a variable is an integer, string, or other type. In a statically typed language, the developer must declare the type of the variable upfront, so that the compiler can take advantage of that information. The post Sorbet: Typed Ruby with Dmitry Petrashko appear...

ReactJS developers have lots of options for building their applications, and those options are not easy to work through. State management, concurrency, networking, and testing all have elements of complexity and a wide range of available tools. Take a look at any specific area of JavaScript application development, and you can find highly varied opinions. The post React Best Practices with Kent Do...

JavaScript fatigue. This phrase has been used to describe the confusion and exhaustion around the volume of different tools required to be productive as a JavaScript developer. Frameworks, package managers, typing systems, state management, GraphQL, and deployment systems–there are so many decisions to make. In addition to the present-day tooling choices, a JavaScript developer needs The pos...

Full-stack JavaScript applications have been possible since the creation of NodeJS in 2009.
