What stack-frame does

When your web application crashes or throws an error, the browser generates a stack trace—a text dump showing which functions called which, and where things went wrong. That raw text is hard to parse and even harder to display nicely to users. Stack-frame takes that messy error information and converts it into clean, structured data that your application can actually work with.

Think of it like parsing a receipt. A receipt is just a long string of text, but if you convert it into structured objects (date, items, total, tax), you can do useful things with it—display it nicely, search it, validate it, or send it to a server. Stack-frame does the same for browser errors: it takes the error's call stack and turns it into organized objects with fields like function name, file path, and line number.

This becomes useful when you're building error reporting tools, debugging dashboards, or user-facing error messages. Instead of showing users a wall of cryptic text, you can display a clean list: "Error in getUserData (api.js, line 42) called from handleClick (app.js, line 15)." Developers working on libraries that need to parse and report errors—like error tracking services or enhanced debugging tools—would use this to reliably extract meaning from browser stack traces.

The README mentions this is "a set of packages," suggesting it's a modular collection of tools focused specifically on managing and parsing these stack frame objects. While the README itself doesn't go into technical detail about how the parsing works or what specific formats it handles, the core idea is straightforward: take raw browser error data and make it usable.
