What is extsprintf?

The extsprintf npm package provides extended sprintf-style formatting capabilities. It is designed to offer more powerful and flexible string formatting options than the traditional sprintf function found in many programming languages. This package allows for formatting strings with placeholders, enabling the insertion of variable content in a template-like fashion. It supports various formatting types, including numbers, strings, and JSON objects, making it suitable for a wide range of applications such as logging, message formatting, and text processing.

What are extsprintf's main functionalities?

Basic String Formatting

This feature allows for basic string formatting using placeholders for strings (%s) and decimal integers (%d). It is useful for constructing messages with dynamic values.

"%s is %d years old.", 'John', 25

Conditional Formatting

Conditional formatting supports inserting values from an object into a string based on property names. This is particularly useful for templating and creating more readable code.

"%(name)s is %(age)d years old.", { name: 'John', age: 25 }

JSON Formatting

This feature allows for the formatting of objects as JSON strings using the %j placeholder. It's useful for logging or displaying structured data in a string format.

"%j", { name: 'John', age: 25 }
