  Kreya, a Postman Alternative2022 · kreya.app · ▲71

  Hi HN! For over a year we've been working on Kreya. At first, it only supported gRPC, because the alternative tools (eg. BloomRPC) were very limited in their functionality. Since then, we have added many features, trying hard to keep the UI clean while still supporting advanced use cases. Yesterday, we released Kreya v1.8, which added support for REST! In our opinion, Kreya is a good alternative to the existing tools out there. Sure, it may not support all the features that Postman has. But we think that Kreya has some innovative approaches (eg. authentication or API importers) that users…

  Tetris in a PDF▲1,289

  I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
