> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
|
|
|
|
You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.

## Install
|
|
|
|
```
|
|
$ npm install ansi-styles
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const style = require('ansi-styles');
|
|
|
|
console.log(`${style.green.open}Hello world!${style.green.close}`);
|
|
|
|
|
|
// Color conversion between 16/256/truecolor
|
|
// NOTE: If conversion goes to 16 colors or 256 colors, the original color
|
|
// may be degraded to fit that color palette. This means terminals
|
|
// that do not support 16 million colors will best-match the
|
|
// original color.
|
|
console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
|
|
console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
|
|
console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
|
|
```
|
|
|
|
## API
|
|
|
|
Each style has an `open` and `close` property.

## Advanced usage
|
|
|
|
By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
|
|
|
|
- `style.modifier`
|
|
- `style.color`
|
|
- `style.bgColor`
|
|
|
|
###### Example
|
|
|
|
```js
|
|
console.log(style.color.green.open);
|
|
```
|
|
|
|
Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
|
|
|
|
###### Example
|
|
|
|
```js
|
|
console.log(style.codes.get(36));
|
|
//=> 39
|
|
```
|
|
|
|
|
|
## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
|
|
|
|
`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
|
|
|
|
To use these, call the associated conversion function with the intended output, for example:
|
|
|
|
```js
|
|
style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
|
|
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
|
|
|
|
style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
|
|
style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
|
|
|
|
style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
|
|
style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
|
|
```
