davepacheco/node-extsprintf

This is a JavaScript implementation of an extended version of the C `sprintf` function, designed for Node.js environments. It supports basic formatting options like field alignment, zero-padding, numeric signs, and field width, along with special conversions for JSON objects (`%j`) and Error objects (`%r`). The project is intended for Node.js developers who need flexible string formatting capabilities, particularly for logging, debugging, or generating formatted output in their applications.
