What is pupa?

The pupa npm package is a simple string interpolation library. It allows you to replace placeholders in a string with actual values from an object or an array. It is useful for templating and customizing messages or configurations.

What are pupa's main functionalities?

String interpolation with an object

This feature allows you to interpolate values from an object into a string. For example, if you have an object with properties 'name' and 'notifications', pupa can replace the placeholders in the string with the corresponding values from the object.

"Hello, {name}! You have {notifications} new notifications."

String interpolation with an array

This feature allows you to interpolate values from an array into a string. The placeholders are indexed based on the array's indices, allowing you to insert array elements into the string at the specified positions.

"Hello, {0}! You are number {1} in line."

Nested object interpolation

Pupa also supports nested object interpolation, where you can access nested properties within an object to replace placeholders in a string.

"Hello, {user.name}! Your role is {user.role}."

Escape interpolation syntax

If you need to include the interpolation syntax as a literal part of the string, you can escape it using a backslash. This tells pupa not to interpret it as a placeholder.

"This is a message with an escaped placeholder: \{escaped\}"
