What is esre?

esre is a tool that automatically formats JavaScript code so that everyone on a team ends up with the same style. Instead of developers arguing about tabs versus spaces, where to put braces, or how to indent lines, they just run their code through this tool before saving or sharing it. The idea is to remove style debates from your team or open-source project entirely. The way it works is straightforward: you write your JavaScript however you want, and then you run it through esre before you commit your changes or before a linter checks your code. The tool rewrites the formatting to match a shared configuration file that everyone on the project agrees to use. The README describes it as "fully configurable," meaning you have control over the formatting rules rather than being locked into someone else's opinionated defaults. Beyond that high-level description, the README doesn't go into detail on how to set up or fine-tune those configurations. This tool is for development teams and open-source contributors who are tired of style-related friction. If you've ever had a code review derailed by someone asking you to move a curly brace to the next line, or had an automated linter complain about spacing instead of catching real bugs, this is the kind of tool that addresses that pain. A startup with several developers contributing to the same codebase, for example, could use it to keep everything visually consistent without forcing anyone to change how they naturally type out their code. What stands out about the project is its emphasis on being fully configurable, which suggests it takes a different philosophical approach than some popular formatters that enforce strict, built-in opinions. That said, the README is quite sparse, it doesn't list specific formatting options, installation steps, or integration details, so you'd need to explore the repository itself to understand the full scope of what it can do.
