Custom Inspects

Some experiments with custom inspects for Deno/NodeJS console logging.

Usage

Deno

import { patch, inspectBytes } from '@li/custom-inspects'

patch(Uint8Array.prototype, inspectBytes)

console.info(await Deno.readFile('./img/Example.jpg'))

// Uint8Array(25303) [
//   ## x0 x1 x2 x3 x4 x5 x6 x7 x8 x9 xa xb xc xd xe xf
//   0x ff d8 ff e0 00 10 4a 46 49 46 00 01 01 01 00 48 ......JFIF.....H

// ]

NodeJS

import * as fs from 'node:fs/promises'
import { patch, inspectBytes } from '@li/custom-inspects'

patch(Uint8Array.prototype, inspectBytes)
patch(Buffer.prototype, inspectBytes)

console.info(await fs.readFile('./img/Example.jpg'))

// Buffer(25303) [
//   ...
// ]
