Changelog

4.1.0 (2025-05-28)

feat: add readonly level property to get the detected color support level:
- 0 - no colors,
- 1 - 16 colors,
- 2 - 256 colors,
- 3 - truecolor.

4.0.0 (2025-05-08)

Release v4.

Pre release note: ✨ Ansis v4 - Smaller package, and cleaner API

Ansis v4 drops legacy baggage and unused artifacts. This release brings a stable and more compact ANSI library. v4.0.0 is 12.4% smaller than v3.17.0.

4.0.0-beta.21 (2025-04-24)

⚠️ BREAKING CHANGE

feat: drop support for Deno 1.x (EOL - 9 Oct 2024) and add support for Deno 2.0+, #37 Backported from 3.18.0-beta.0

4.0.0-beta.20 (2025-04-21)

⚠️ BREAKING CHANGE

Removed unused and rarely used aliases for gray and bgGray:

grey, bgGrey - British spelling, uncommon, redundant aliases for gray and bgGray
blackBright, bgBlackBright - Spec-style names for "bright black", less intuitive, rarely used, and awkward in practice

Supporting three separate names for the same color is too much and introduces ambiguity into the API.

Migrating

Replace deprecated aliases with the preferred standard names:

- ansis.grey('text')
- ansis.blackBright('text')
+ ansis.gray('text')

- ansis.bgGrey('text')
- ansis.bgBlackBright('text')
+ ansis.bgGray('text')

4.0.0-beta.19 (2025-04-20)

⚠️ BREAKING CHANGE

The unused AnsiColorsExtend type has been removed.

This type was intended to support extended theme colors, but it was never used in other projects. If you relied on it in your own code (e.g. for typing custom styles), you can easily define it yourself.

Migrating

If you previously used the AnsiColorsExtend type, you’ll now need to define a custom utility type. Here's an example how to update your code:

- import ansis, { AnsiColorsExtend } from 'ansis';
+ import ansis, { AnsiColors } from 'ansis';

+ type AnsiColorsExtend<T extends string> = AnsiColors | (T & Record<never, never>);

const myTheme = {
  orange: '#FFAB40',
};

// Extend ansis with custom colors
const colors = ansis.extend(myTheme);

// Custom logger supporting both built-in and extended styles
const log = (style: AnsiColorsExtend<keyof typeof myTheme>, message: string) => {
  console.log(colors[style](message));
}

log('orange', 'message'); // extended color

This change ensures compatibility with the latest version of Ansis, where AnsiColorsExtend is no longer available.

4.0.0-beta.18 (2025-04-18)

⚠️ BREAKING CHANGE (if using 256-color functions)

The following legacy method aliases have been removed:

❌ Removed Method	✅ Use Instead
`ansi256(code)`	`fg(code)`
`bgAnsi256(code)`	`bg(code)`

These aliases were originally added for compatibility with Chalk. Starting with this release, Ansis focuses on a cleaner and compact API, free from duplicated methods and legacy layers.

Why `fg()` and `bg()` are better than `ansi256()` and `bgAnsi256()`

Ansis has grown beyond being a Chalk-compatible alternative - it's now a modern and compact ANSI library with its own identity.

Clear and expressive API

ansis.fg(code) and ansis.bg(code) are shorter more elegant than ansis.ansi256(code) and ansis.bgAnsi256(code)
fg and bg clearly describe their purpose: setting foreground and background colors
These method names align with conventions used by many other color libraries
Introduced in 2021-12-29, fg() and bg() are already being used in GitHub projects
Removing duplicates makes the API cleaner and more compact

Migrating

Updating from a previous version is simple:

import ansis from 'ansis';

- ansis.ansi256(196)('Error')
+ ansis.fg(196)('Error')

- ansis.bgAnsi256(21)('Info')
+ ansis.bg(21)('Info')

Alternatively, to keep compatibility with existing code:

- import { ansi256, bgAnsi256 } from 'ansis';
+ import { fg as ansi256, bg as bgAnsi256 } from 'ansis';

ansi256(196)('Error')
bgAnsi256(21)('Info')

No other changes are required - everything else remains fully compatible.

4.0.0-beta.17 (2025-04-18)

feat: refactor .d.ts and reduce the package size

4.0.0-beta.16 (2025-04-16)

⚠️ BREAKING CHANGE: Improved `extend()` method

The extend() method has been redesigned for better TypeScript support and flexibility.

Old behavior:

extend<U extends string>(colors: Record<U, string | P>): asserts this is Ansis & Record<U, Ansis>;

Modifies the current instance in-place.
Returns void.

✅ Worked with default instance:

import ansis from 'ansis';

ansis.extend({ pink: '#FF75D1' });
console.log(ansis.pink('foo'));

❌ Limitation - Did not work with newly created instances:

import { Ansis } from 'ansis';

const ansis = new Ansis();
ansis.extend({ pink: '#FF75D1' });
console.log(ansis.pink('Hello')); // TS2339: Property 'pink' does not exist

New behavior:

extend<U extends string>(colors: Record<U, string | P>): Ansis & Record<U, Ansis>;

Returns a new extended instance with full type support.

✅ Works with both ansis and new Ansis():

import ansis, { Ansis } from 'ansis';

const colors = ansis.extend({ pink: '#FF75D1' });
console.log(colors.pink('foo'));

const custom = new Ansis().extend({ apple: '#4FA83D' });
console.log(custom.apple('bar'));

Why this change?

TypeScript cannot widen the type of an existing variable when using asserts. This means the old approach only worked for top-level constants like ansis, not new instances. By returning the extended instance, the new approach enables full type inference in all scenarios.

Summary:

asserts version removed
extend() now returns a new instance with extended types
Cleaner, safer, and fully compatible with all usage patterns

Migrating

The new extend() method now returns an extended instance instead of modifying the original in-place. To migrate, assign the result of extend() to a new variable (avoid reassigning the original instance):

import ansis from 'ansis';

- ansis.extend({ pink: '#FF75D1' });
+ const theme = ansis.extend({ pink: '#FF75D1' });

- console.log(ansis.pink('foo'));
+ console.log(theme.pink('foo'));

import { Ansis } from 'ansis';

- ansis.extend({ pink: '#FF75D1' });
+ const ansis = new Ansis().extend({ pink: '#FF75D1' });

console.log(ansis.pink('foo'));

Features

Manually set the color level

Ansis automatically detects color support, but you can manually set the color level. You can create a new instance of Ansis with the desired color level.

Disable colors:

import { Ansis } from 'ansis';

const custom = new Ansis(0);
console.log(custom.red`foo`); // Output: plain string, no ANSI codes

Use only basic colors:

import { Ansis } from 'ansis';

const custom = new Ansis(1);
console.log(custom.hex('#FFAB40')`Orange`); // Output: fallback to yellowBright

4.0.0-beta.14 (2025-04-13)

feat: reduce size of index.d.ts file

4.0.0-beta.13 (2025-04-12)

feat: reduce the package size

4.0.0-beta.9 (2025-03-13)

feat: slightly improve performance for hex function

4.0.0-beta.4 (2025-03-08)

Features

Dropped `xterm-direct` terminfo check for truecolor support (not a breaking change)

The xterm-direct detection logic (introduced in v3.5.0) has been removed, as it's unnecessary for identifying truecolor-capable terminals.

Note

No terminal emulator sets TERM=xterm-direct by default. Modern terminals, including KDE Konsole, typically use TERM=xterm-256color along with COLORTERM=truecolor to indicate truecolor support.

4.0.0-beta.2 (2025-03-07)

Fixes

Defaults to 16 colors when terminal color support is unknown

Ansis now defaults uses 16 colors if it cannot detect support for 256 colors or truecolor.

Old behavior: Unknown terminal → used truecolor (could result in incorrect colors)
New behavior: Unknown terminal → uses only 16 colors (ensures broad compatibility)

Note

This is not a breaking change. Ansis gracefully interpolates higher color depths (truecolor and 256 colors) down to 16 colors when using fg(), hex() or rgb(). To explicitly enable truecolor, set the environment variable COLORTERM=24bit or FORCE_COLOR=3.

4.0.0-beta.1 (2025-03-03)

BREAKING CHANGE (very unlikely impact): Removed non-standard `strike` style (alias for `strikethrough`)

The legacy strike alias has been removed to clean up the API and stay consistent with ANSI style conventions.

The strike style was rarely (if ever) used and added unnecessary redundancy.
No usage of ansis.strike() was found in public GitHub repositories.
Other ANSI libraries use the standard strikethrough name exclusively.

Migrating

If you're using strike style, replace it with strikethrough.

Features

Support escape sequences in tagged template literals

Ansis now treats tagged template literals the same way as normal strings, returning the same result as the standard function call.

Example with \n (newline, unescaped):

red('prev\nnext')
red`prev\nnext`

Output:

prev
next

Example with escaped backslash:

red('prev\\next')
red`prev\\next`

Output:

prev\next

BREAKING CHANGE

In the new major version 3.x are removed unused styles and methods.

⚠️ Warning

Before update, please check your code whether is used deleted styles and methods.

Support Node.js

Drop supports for Node <= 14. Minimal supported version is 15.0.0 (Released 2020-10-20). In the theory the v3 can works with Node12, but we can't test it.

Deleted DEPRECATED named import syntax (since `v3.3.0`)

ESM

- import { red } from 'ansis/colors';
+ import { red } from 'ansis';

CJS

- const { red } = require('ansis/colors');
+ const { red } = require('ansis');

Deleted styles

The not widely supported styles are deleted:

faint (alias for dim), replace in your code with dim
doubleUnderline, replace in your code with underline
frame, replace in your code with underline
encircle, replace in your code with underline
overline, replace in your code with underline

Deleted methods

The methods are deleted:

ansi, replace in your code with fg
bgAnsi, replace in your code with bg

Deleted clamp in functions

The clamp (0, 255) for the ANSI 256 codes and RGB values is removed, because is unused. You should self check the function arguments.

The affected functions:

fg - expected a code in the range 0 - 255
bg - expected a code in the range0 - 255
rgb - expected r, g, b values in the range 0 - 255
bgRgb - expected r, g, b values in the range 0 - 255
