It's like the console wars — different camps say "our console is better, it has more teraflops." In reality, nobody cares about that — buyers will get the console that has the games.

I made a small application that helps "decipher" the stack trace of minified JS code.

It works like this: you paste a stack trace into the textarea, provide one or more source maps (by pasting or through a file input), and the application applies the source maps to the stack trace and displays the "original" stack trace. This way, you can see the exact position of the error in the original file.

When it might be helpful:

- You found an error in a production environment, but you don't host source maps and can't see on the developer tools where exactly it occurred - The user found a bug and sent you a stack trace - You get the stack trace from monitoring (e.g., Sentry) but do not configure it to work with source maps.

If you feel that such an application could be helpful to you, feel free to try it at https://sourcemaps.tools. The source is available at https://github.com/rmuratov/sourcemap.tools.

It probably contains bugs but should work in simple cases... or at least I hope :)

There are other features that might be implemented, but I wonder if this could be useful to anyone at all, so I decided to collect some feedback first.

I will appreciate any feedback - first impressions, opinions, bug reports, feature requests.

Inspired by https://sourcemaps.info/, but does everything on the client and does not try to fetch sources or source maps.

It helps decipher JS error stack traces by applying source maps to them. In my previous company, we struggled to configure Sentry to work with source maps, and every error message was cryptic due to minification. First, I created a little command line utility and later made it a web app.

Just some charts to summarize my monthly finance activity based on hldger journal.

An app where you can draw with emojis and then copy your art as text and send it via, e.g., messenger. I want to make it a full-featured drawing app with undo/redo, line drawing tool, circle/square, etc.

A tool to unminify JavaScript stack traces. You paste your stack trace and provide source maps, and it deciphers your stack trace and allows you to find the origin of an error.

Yes, that's just it. I do not use anything like a language server.

But. I keep my journal files in a folder and open it using the VS Code project file.

File's name is ledger.code-workspace

{ "folders": [{ "path": "/path/to/journal/directory" }] }

I used to dread it too. But actually, in normal life, the volume of daily transactions is not that large. Besides, filling out a journal disciplines you. And VS Code does autocomplete for accounts and payees.
