Kill the loading spinner with local-first data and reactive SQL

It’s not every day that a radically new architecture comes along, but here we are: in-browser SQLite, combined with reactive SQL and auto-syncing. The promise is instant interactivity on the front end, while maintaining data symmetry with the back end. As a direct challenger to the RESTful group-think that has dominated web development for a decade, it is well worth a look.  Not really new, but improved This idea isn’t brand new. Developers have been doing this kind of thing in one fashion or another for years (think of how some apps work offline). But this new-generation stack feels different, and it’s starting to see broader appeal. It’s called local-first data. I recently covered the idea at a high level. Now it’s time for a look at the nitty gritty. The concept is simple. Instead of asking a remote server for permission to change a number, your app writes state directly to a local SQLite database running in the browser (via WebAssembly). A sophisticated background engine then hand

It’s harder than it might seem to create a stand-alone Python app. It’s also harder than you might think to reliably back up SQLite databases, but Python has the tools for it. And while it’s not easy to install Python on an air-gapped machine, it absolutely can be done. Top picks for Python readers on InfoWorld Why it’s so hard to create stand-alone Python apps Python’s dynamism is one of its most powerful features. It’s also why making stand-alone apps from Python programs is such a bear. How to back up SQLite databases the right way (not by copying them!) SQLite databases are single files, so backing them up just means copying them, right? Wrong. Make backups the proper way by using SQLite’s own backup mechanisms. Python’s new frozendict type, demonstrated A long-desired and -debated core addition to the language: a “frozen” or immutable dictionary, is coming in Python 3.15. See where it’ll be most useful in our live demo. How to set up Python on an air-gapped system Stuck working wi

In this tutorial, we explore how to build a fully functional background task processing system using Huey directly, without relying on Redis. We configure a SQLite-backed Huey instance, start a real consumer in the notebook, and implement advanced task patterns, including retries, priorities, scheduling, pipelines, locking, and monitoring via signals. As we move step by […] The post A Coding Guide to Build a Production-Grade Background Task Processing System Using Huey with SQLite, Scheduling, Retries, Pipelines, and Concurrency Control appeared first on MarkTechPost.
