What is @stdlib/assert-has-node-buffer-support?

@stdlib/assert-has-node-buffer-support is a package that provides a utility to check if the current environment supports Node.js Buffer objects. This can be useful for ensuring compatibility and functionality in environments where Buffer support is required.

What are @stdlib/assert-has-node-buffer-support's main functionalities?

Check Buffer Support

This feature allows you to check if the current environment supports Node.js Buffer objects. The function returns a boolean value indicating the presence of Buffer support.

const hasBufferSupport = require('@stdlib/assert-has-node-buffer-support');

if (hasBufferSupport()) {
  console.log('Buffer support is available.');
} else {
  console.log('Buffer support is not available.');
}

Other packages similar to @stdlib/assert-has-node-buffer-support

buffer

The 'buffer' package is a Node.js core module that provides a way to handle binary data. While it does not specifically check for Buffer support, it is the primary package used for working with Buffer objects in Node.js. It is more comprehensive in terms of functionality for handling binary data compared to @stdlib/assert-has-node-buffer-support.

is-buffer

The 'is-buffer' package is a simple utility to check if a given object is a Buffer. Unlike @stdlib/assert-has-node-buffer-support, which checks for the environment's support for Buffer objects, 'is-buffer' checks if a specific object is an instance of Buffer. It is useful for type-checking in applications that handle binary data.
