wasp

Exploring, less verbose web-frameworks for my codegen product. Anyone used wasp-js in production? They claim a lot of things, but wanted to make sure it can handle workers and async jobs. https://github.com/wasp-lang/wasp Could only find three case-studies of actual deployment on their site. Hopefully the founders will respond.

Yeah, both RedwoodJS and BlitzJS appeared at about the same time as we started Wasp (https://github.com/wasp-lang/wasp), with the same mission of being Rails/Laravel for JS. We were excited to see that several instances of the same core idea appeared at the same time, and it gave us validation that we're on the right path. A bit sad about Redwood moving away from the original vision, but interested to see where this new direction takes it.

Ruby on Rails has an amazing DX (e.g. engines). We are trying to recreate that for JS with Wasp (https://github.com/wasp-lang/wasp)

Wasp (https://github.com/wasp-lang/wasp) has actually worked out quite well! It just crossed 10k stars on GitHub and is currently the fastest-growing full-stack framework for React & Node.js. It's being used in both startups and enterprises. Although Wasp has its own DSL/compiler, the secret to its adoption is probably that it works with the existing stack, like React & Node.js. From the developer's perspective, it feels like a framework; the "compiler" part is just what gives it its superpowers.

Aider is one of my favorite AI agents, especially because it can work with existing codebases. We've seen a lot of good results from folks who used it with Wasp (https://github.com/wasp-lang/wasp) - a full-stack web framework I'm working on.

I have no idea what other folks are doing to stabilize it. For me, I needed a ton (hundreds of thousands) of JS/TS(X) files parsed and ingested into other data pipelines and the segfaults were constant^. If you had a system where single files were only parsed on-demand via separate worker thread and the consequence of a segfault was the text appearing monotone, I'm sure you'd be alright. ^One example: https://github.com/wasp-lang/wasp/blob/main/waspc/data/Gener...

This sounds cool! How would we go about integrating this with https://github.com/wasp-lang/wasp ?

Although AI has been all the rage lately, I was actually always excited the most by building a compiler. After a few years of dabbling with it, I created one together with my brother: https://github.com/wasp-lang/wasp It is a DSL (a simple config language for building web apps) so not that complicated as a Turing-complete language, but still a lot of concepts remain. As a good starting resources for building your own compiler I'd also recommend Crafting Interpreters, super nicely explained and fun to go through: https://craftinginterpreters.com/

I know it is common to think that Haskell is used only in academia and side/weird-projects, but there is a decent amount of companies using Haskell - e.g. we use Haskell in production for developing a DSL / web framework for building web apps (https://github.com/wasp-lang/wasp)! I participated teaching students Haskell on my alma mater this year and "what can Haskell be used for" was a common question, with genuine expectation that the answer will be it is limited to only specific use cases. I would answer that it can be used anywhere where languages like Java, C#, Go, and similar can be used -> it is a general programming language that uses garbage collector! And while somewhat harder to learn due to abstractions that we are all not used to, it is a delight to express business logic in it once you get to know it well. The biggest factor

Absolutely, but if I had to rank Open Source projects by "enjoyment level to work on", I would rank a 10+ year old Java project primarily used by enterprise companies quite low on my list! Compare that to something like Bun.js[0] which is "sexy" and written in a "cool" programming language (Zig). Or Wasp[1] which is built with Haskell and is trying to define a new programming language designed to make common dev patterns less painful. Those projects are naturally going to soak up smart people that have extra energy to share because they hate their day job but need to pay their bills. (imo) Who is left that wants to bang their head against a legacy codebase like Log4j? Maybe somebody that feels there is "clout" to be had from it?

Our compiler is split into Analyzer which produces AppSpec, which is the central intermediate representation, and then Generator, that based on AppSpec produces the react / node web app. So yes, you could use just Analyzer to produce AppSpec, and then write your own generator that will based on that AppSpec generate your own code! AppSpec currently exists only as Haskell in-memory data structure, but it could be relatively easy serialized via JSON and then imported in some other language. You can see more about this in this README, there is a nice diagram showing parts of compiler (Analyzer, AppSpec, Generator): https://github.com/wasp-lang/wasp/tree/main/waspc#readme . The reason why we already ensured this split was because the plan is in the future to have multiple different Generators, and also to allow users to write either their who

Our compiler stack is in Haskell so we initially started with Parsec (parser combinator library) and then eventually switched to Happy (parser generator that Haskell uses itself) since at first we didn't have a formal grammar defined so that made us write a lot of code for every little addition to the language (it's a simple declarative DSL, https://github.com/wasp-lang/wasp). The problem we're now facing with Happy is that it doesn't really have support for error recovery. We're trying to implement LSP so recovery is important in order to have proper syntax highlighting and error reporting in an IDE. Wondering how well ANTLR covers this, I was quite surprised to find out that Happy has so little support for it.
