Project mention: A brief history of web development. And why your framework doesn't matter | news.ycombinator.com | 2024-04-29

> It’s important to be aware of what you are getting if you go with React, and what you are getting is a far cry from what a framework would offer, with all the corresponding pros and cons.

Would you like to elaborate on that?

In my experience, with something as great, size/ecosystem-wise as React, there will almost always be at least one "mainstream" package for whatever you might want to do with it, that integrates pretty well. Where a lot of things might come out of the box with a framework, with a library I often find myself just needing to install the "right" package, and from there it's pretty much the same.

For example, using https://angular.io/guide/i18n-overview or installing and using https://react.i18next.com/

Or something like https://angular.io/guide/form-validation out of the box, vs installing and using https://formik.org/

Or perhaps https://angular.io/guide/router vs https://reactrouter.com/en/main

Even adding something that's not there out of the box is pretty much the same, like https://primeng.org/ or https://primereact.org/

React will typically have more fragmentation and therefore also choice, but I don't see those two experiences as that different. Updates and version management/supply chain will inevitably be more of a mess with the library, admittedly.

Now, projects like Next https://nextjs.org/ exist and add what some might regard as the missing pieces and work well if you want something opinionated and with lots of features out of the box, but a lot of those features (like SSR) are actually pretty advanced and not always even necessary.

• Lark

  35 4,510 7.5 Python

  Lark is a parsing toolkit for Python, built with a focus on ergonomics, performance and modularity.

  

Project mention: Show HN: I wrote a RDBMS (SQLite clone) from scratch in pure Python | news.ycombinator.com | 2023-08-13

Lark supports, and recommends, writing and storing the grammar in a .lark file. We have syntax highlighting support in all major IDEs, and even in github itself. For example, here is Lark's built-in grammar for Python: https://github.com/lark-parser/lark/blob/master/lark/grammar...

You can also test grammars "live" in our online IDE: https://www.lark-parser.org/ide/

The rationale is that it's more terse and has less visual clutter than a DSL over Python, which makes it easier to read and write.

The most substantial project that I have to show for my knowledge of the lower level topics is this project I work on in my spare-time called erdtree and I'm really banking on that to stand-in as "experience" in the absence of professional systems experience.
