    Hello all To preface this is just something I've been making as a learning exercise, so all feedback is appreciated. This is a tool that converts JSON schemas into TypeScript utility classes for use in Deno. Automatic Type Generation: Typescript interfaces for the compressed and uncompressed versions of your data. Compression & Decompression: Compress and decompress your data. Validation: Built-in data validation using Ajv ensures your data adheres to the schema. Reusability: Once generated, the utility classes can be used in other Deno projects. It currently only supports a subset of JSON…

    Hi HN, I’m Joan, the developer of Quicklang. I made this app to easily translate and keep in sync all my localization JSON files for my side projects. While searching online for a similar tool, I only found enterprise solutions that do not allow direct editing of JSON files. I used to use ChatGPT to translate the JSON translation file changes before coding Quicklang. However, I realized that ChatGPT only allows you to input short content for translation into another language (even if you provide a .json file), and each time I had to request translations for one language at a time. So, I…

    I've been at it again, just sharing my simple JSON data inspection tool, love webdev and single page apps, this one took 4 days and was a lot of fun. The code is not obfuscated so you can inspect it and see how it works (very simple, server side is even more simple) Pretty much just do a POST of your JSON data from within your code and it will convert it into a basic table for instant search and sort. Made with love for the fun of it, no ads, no paid anything, it's totally free. Please only send in sanitized/test data only, this is meant to help make webdev a bit easier and more fun.…
