    TypeScript

    TypeScript

    TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps. TypeScript understands JavaScript and uses type inference to give you great tooling without additional code. TypeScript was used by 78% of the 2020 State of JS respondents, with 93% saying they would use it again. The most common kinds of errors that programmers write can be described as type errors: a certain kind of value was used where a different kind of value was expected. This could be due to simple typos, a failure to understand the API surface of a library, incorrect assumptions about runtime behavior, or other errors.

    Backbone.js

    Backbone.js

    Backbone.js

    Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server.

    Nova

    Panic

    If we're being honest, Mac apps are a bit of a lost art. There are great reasons to make cross-platform apps — to start, they're cross-platform — but it's just not who we are. Founded as a Mac software company in 1997, our joy at Panic comes from building things that feel truly, well, Mac-like. Long ago, we created Coda, an all-in-one Mac web editor that broke new ground. But when we started work on Nova, we looked at where the web was today, and where we needed to be. It was time for a fresh start. It all starts with our first-class text-editor. It's new, hyper-fast, and flexible, with all the features you want: smart autocomplete, multiple cursors, a Minimap, editor overscroll, tag pairs and brackets, and way, way more. For the curious, Nova has built-in support for CoffeeScript, CSS, Diff, ERB, Haml, HTML, INI, JavaScript, JSON, JSX, Less, Lua, Markdown, Perl, PHP, Python, Ruby, Sass, SCSS, Smarty, SQL, TSX, TypeScript, XML, and YAML.

After the content is served and the network is idle Nullstack JavaScript is loaded, the state of the application is restored through hydration and it becomes a single-page application. Subsequent server functions will fetch JSON from an automatically generated microservice API, deserialize the response, update the application state, and rerender the page out of the box. A full stack lifecycle combined with a feature-driven mindset allows you to write clean and reusable code without the need to create APIs manually.
