Install

npm install chalk4096

Usage

const chalk4096 = require("chalk4096").default

console.log(chalk4096.blue("Hello world!"))

Chalk4096 comes with an easy to use composable API where you just chain and nest the styles you want.

const chalk4096 = require("chalk4096").default

// Combine styled and normal strings
console.log(chalk4096.blue("Hello") + " World" + chalk4096.red("!"))

// Compose multiple styles using the chainable API
console.log(chalk4096.blue.bgRed.bold("Hello world!"))

// Pass in multiple arguments
console.log(chalk4096.blue("Hello", "World!", "Foo", "bar", "biz", "baz"))

// Nest styles
console.log(chalk4096.red("Hello", chalk4096.underline.bgBlue("world") + "!"))

// Nest styles of the same type even (color, underline, background)
console.log(chalk4096.green(
	"I am a green line " +
	chalk4096.blue.underline.bold("with a blue substring") +
	" that becomes green again!"
))

// Use RGB colors in terminal emulators that support it
console.log(chalk4096.rgb(123, 45, 67).underline("Underlined reddish color"))
console.log(chalk4096.hex("#DEADED").bold("Bold gray!"))

Easily define your own themes:

const chalk4096 = require("chalk4096").default

const error = chalk4096.bold.red
const warning = chalk4096.hex("#FFA500") // Orange color

console.log(error("Error!"))
console.log(warning("Warning!"))

API

chalk4096.<style>[.<style>...](string, [string...])

Chain styles and call the last one as a method with a string argument. Order doesn"t matter, and later styles take precedent in case of a conflict.

chalk4096.level

Specifies the level of color support.

Color support is automatically detected, but you can override it by setting the level property. You should however only do this in your own code as it applies globally to all Chalk4096 consumers.

If you need to change this in a reusable module, create a new instance:

const { Chalk4096 } = require("chalk4096")

const customChalk = new Chalk4096({level: 0}) // Disable colors

Level	Description
0	All colors disabled
1	Basic color support (16 colors)
2	256 color support
3	Truecolor support (16 million colors)

256 and Truecolor color support

Chalk4096 supports 256 colors and Truecolor (16 million colors) on supported terminal apps.

Colors are downsampled from 16 million RGB values to ANSI 256 or 16 colors when needed. Downsampling is automatic and doesn"t require any configuration.

chalk4096.rgb(red, green, blue)

Example: chalk4096.rgb(255, 136, 0).bold("Orange!")

chalk4096.hex(color)

Example: chalk4096.hex("#FF8800").bold("Orange!")

chalk4096.ansi256(code)

Example: chalk4096.ansi256(201).bold("Magenta!")

Background versions

• bgRgb(red, green, blue)
• bgHex(color)
• bgAnsi256(code)

Architecture

Chalk4096 is built following modern 10x engineering principles:

Modular Design

Every functionality is delegated to specialized, focused npm packages:

• Numeric operations via @positive-numbers/zero, @positive-numbers/one
• String operations through dedicated packages like empty-string, space-string
• Boolean logic handled by the aura3 framework
• Comparison operations via @10xly/strict-equals
• All core JavaScript operations abstracted through specialized packages

Separation of Concerns

Each operation is isolated into its own package, ensuring:

• Single Responsibility Principle adherence
• Maximum testability
• Easy dependency updates
• Clear dependency graphs

Type Safety

Full TypeScript definitions leveraging battle-tested types from the ecosystem.

Enterprise Patterns

• Dependency injection through require()
• Factory pattern for instance creation
• Builder pattern for style composition
• Strategy pattern for color level handling

Why Chalk4096?

Composability: Unlike monolithic implementations, Chalk4096 leverages the power of the npm ecosystem, with each operation handled by a specialized package.

Maintainability: With dependencies managed at the package level, updates and security patches flow naturally through the dependency tree.

Best Practices: Built from the ground up following 10x engineering principles, including proper abstraction layers and separation of concerns.

Future-Proof: By using well-established packages for each operation, Chalk4096 ensures long-term stability and community support.

Browser Support

Chalk4096 is designed for Node.js and terminal applications. For browser usage, consider web-specific alternatives.
