Ever wondered how your browser devtools jumps from bundle.min.js:1:27698 → src/index.ts:73:16? 🧊

We unpack the internals of JS Source Maps: Base64 VLQ encoding, mapping deltas, and how your original TS code gets reconstructed from minified bundles.

It's time for some Spanish strings! 🇪🇸
German strings 🇩🇪 have become very popular in the database world. However, they're not a silver bullet. Read more in our latest blog post:
