The latest in JavaScript and cross-platform tools

Writing JavaScript without a build system
Quoting the blog post:

I want to talk about what’s appealing to me about build systems, why I (usually) still don’t use them, and why I find it frustrating that some frontend JavaScript libraries require that you use a build system.

I’m writing this because most of the writing I see about JS assumes that you’re using a build system, and it can be hard to navigate for folks like me who write very simple small JavaScript projects that don’t require a build system.

RxDB - A fast, offline-first, reactive database for JavaScript Applications Sponsor
RxDB is an offline-first, NoSQL-database for JavaScript Applications like Websites, hybrid Apps, Electron-Apps, and Node.js. Reactive means that you can not only query the current state, but subscribe to all state changes like the result of a query or even a single field of a document.

Merged into Node.js: support for single-executable applications, @nodejs
The current version of this feature is deliberately minimal – more functionality will be added over time:
  • Input: a single JavaScript file
  • Output: a single executable that runs the file
The assumption is that, for now, code is bundled before creating an executable. In the future, executables may contain an internal virtual file system that contains multiple modules and other resources (source).
