Enforce either `Buffer` or `require("buffer").Buffer` (`n/prefer-global/buffer`)

The Buffer class of buffer module is defined as a global variable.

console.log(Buffer === require("buffer").Buffer) //→ true

It will be readable if we use either Buffer consistently.

📖 Rule Details

This rule enforces which Buffer we should use.

This rule has a string option.

{
    "n/prefer-global/buffer": ["error", "always" | "never"]
}

"always" (default) ... enforces to use the global variable Buffer rather than require("buffer").Buffer.
"never" ... enforces to use require("buffer").Buffer rather than the global variable Buffer.

Examples of 👎 incorrect code for this rule:

/*eslint n/prefer-global/buffer: [error]*/

const { Buffer } = require("buffer")
const b = Buffer.alloc(16)

Examples of 👍 correct code for this rule:

/*eslint n/prefer-global/buffer: [error]*/

const b = Buffer.alloc(16)

Examples of 👎 incorrect code for the "never" option:

/*eslint n/prefer-global/buffer: [error, never]*/

const b = Buffer.alloc(16)

Examples of 👍 correct code for the "never" option:

/*eslint n/prefer-global/buffer: [error, never]*/

const { Buffer } = require("buffer")
const b = Buffer.alloc(16)
