> Critters is a plugin that inlines your app's [critical CSS] and lazy-loads the rest.
|
||||
|
||||
## critters [](https://www.npmjs.org/package/critters)
|
||||
|
||||
It's a little different from [other options](#similar-libraries), because it **doesn't use a headless browser** to render content. This tradeoff allows Critters to be very **fast and lightweight**. It also means Critters inlines all CSS rules used by your document, rather than only those needed for above-the-fold content. For alternatives, see [Similar Libraries](#similar-libraries).
|
||||
|
||||
Critters' design makes it a good fit when inlining critical CSS for prerendered/SSR'd Single Page Applications. It was developed to be an excellent compliment to [prerender-loader](https://github.com/GoogleChromeLabs/prerender-loader), combining to dramatically improve first paint time for most Single Page Applications.
|
||||
|
||||
## Features
|
||||
|
||||
- Fast - no browser, few dependencies
|
||||
- Integrates with Webpack [critters-webpack-plugin]
|
||||
- Supports preloading and/or inlining critical fonts
|
||||
- Prunes unused CSS keyframes and media queries
|
||||
- Removes inlined CSS rules from lazy-loaded stylesheets
|
||||
|
||||
## Installation
|
||||
|
||||
First, install Critters as a development dependency:
|
||||
|
||||
```sh
|
||||
npm i -D critters
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```sh
|
||||
yarn add -D critters
|
||||
```
|
||||
|
||||
## Simple Example
|
||||
|
||||
```js
|
||||
import Critters from 'critters';
|
||||
|
||||
const critters = new Critters({
|
||||
// optional configuration (see below)
|
||||
});
|
||||
|
||||
const html = `
|
||||
<style>
|
||||
.red { color: red }
|
||||
.blue { color: blue }
|
||||
</style>
|
||||
<div class="blue">I'm Blue</div>
|
||||
`;
|
||||
|
||||
const inlined = await critters.process(html);
|
||||
|
||||
console.log(inlined);
|
||||
// "<style>.blue{color:blue}</style><div class=\"blue\">I'm Blue</div>"
|
||||
```
|
||||
|
||||
## Usage with webpack
|
||||
|
||||
Critters is also available as a Webpack plugin called [critters-webpack-plugin](https://www.npmjs.org/package/critters-webpack-plugin). [](https://www.npmjs.org/package/critters-webpack-plugin)
|
||||
|
||||
The Webpack plugin supports the same configuration options as the main `critters` package:
|
||||
|
||||
```diff
|
||||
// webpack.config.js
|
||||
+const Critters = require('critters-webpack-plugin');
|
||||
|
||||
module.exports = {
|
||||
plugins: [
|
||||
+ new Critters({
|
||||
+ // optional configuration
|
||||
+ preload: 'swap',
|
||||
+ includeSelectors: [/^\.btn/, '.banner'],
|
||||
+ })
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
That's it! The resultant html will have its critical CSS inlined and the stylesheets lazy-loaded.

||||

|
||||
|
||||
### Include/exclude rules
|
||||
|
||||
We can include or exclude rules to be part of critical CSS by adding comments in the CSS
|
||||
|
||||
Single line comments to include/exclude the next CSS rule
|
||||
|
||||
```css
|
||||
/* critters:exclude */
|
||||
.selector1 {
|
||||
/* this rule will be excluded from critical CSS */
|
||||
}
|
||||
|
||||
.selector2 {
|
||||
/* this will be evaluated normally */
|
||||
}
|
||||
|
||||
/* critters:include */
|
||||
.selector3 {
|
||||
/* this rule will be included in the critical CSS */
|
||||
}
|
||||
|
||||
.selector4 {
|
||||
/* this will be evaluated normally */
|
||||
}
|
||||
```
|
||||
|
||||
Including/Excluding multiple rules by adding start and end markers
|
||||
|
||||
```css
|
||||
/* critters:exclude start */
|
||||
|
||||
.selector1 {
|
||||
/* this rule will be excluded from critical CSS */
|
||||
}
|
||||
|
||||
.selector2 {
|
||||
/* this rule will be excluded from critical CSS */
|
||||
}
|
||||
|
||||
/* critters:exclude end */
|
||||
```
|
||||
|
||||
```css
|
||||
/* critters:include start */
|
||||
|
||||
.selector3 {
|
||||
/* this rule will be included in the critical CSS */
|
||||
}
|
||||
|
||||
.selector4 {
|
||||
/* this rule will be included in the critical CSS */
|
||||
}
|
||||
|
||||
/* critters:include end */
|
||||
```
|
||||
|
||||
### Critters container
|
||||
|
||||
By default Critters evaluates the CSS against the entire input HTML. Critters evaluates the Critical CSS by reconstructing the entire DOM and evaluating the CSS selectors to find matching nodes. Usually this works well as Critters is lightweight and fast.
|
||||
|
||||
For some cases, the input HTML can be very large or deeply nested which makes the reconstructed DOM much larger, which in turn can slow down the critical CSS generation. Critters is not aware of viewport size and what specific nodes are above the fold since there is not a headless browser involved.
|
||||
|
||||
To overcome this issue Critters makes use of **Critters containers**.
|
||||
|
||||
A Critters container mimics the viewport and can be enabled by adding `data-critters-container` into the top level container thats contains the HTML elements above the fold.
|
||||
|
||||
You can estimate the contents of your viewport roughly and add a <div `data-critters-container` > around the contents.
|
||||
|
||||
```html
|
||||
<html>
|
||||
<body>
|
||||
<div class="container">
|
||||
<div data-critters-container>
|
||||
/* HTML inside this container are used to evaluate critical CSS */
|
||||
</div>
|
||||
/* HTML is ignored when evaluating critical CSS */
|
||||
</div>
|
||||
<footer></footer>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
_Note: This is an easy way to improve the performance of Critters_
|
||||
|
||||
### Logger
|
||||
|
||||
Custom logger interface:
|
||||
|
||||
Type: [object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)
|
||||
|
||||
#### Properties
|
||||
|
||||
- `trace` **function ([String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String))** Prints a trace message
|
||||
- `debug` **function ([String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String))** Prints a debug message
|
||||
- `info` **function ([String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String))** Prints an information message
|
||||
- `warn` **function ([String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String))** Prints a warning message
|
||||
- `error` **function ([String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String))** Prints an error message
|
||||
|
||||
### LogLevel
|
||||
|
||||
Controls log level of the plugin. Specifies the level the logger should use. A logger will
|
||||
not produce output for any log level beneath the specified level. Available levels and order
|
||||
are:
|
||||
|
||||
- **"info"** _(default)_
|
||||
- **"warn"**
|
||||
- **"error"**
|
||||
- **"trace"**
|
||||
- **"debug"**
|
||||
- **"silent"**
|
||||
|
||||
Type: (`"info"` | `"warn"` | `"error"` | `"trace"` | `"debug"` | `"silent"`)
|
||||
|
||||
### PreloadStrategy
|
||||
|
||||
The mechanism to use for lazy-loading stylesheets.
|
||||
|
||||
Note: <kbd>JS</kbd> indicates a strategy requiring JavaScript (falls back to `<noscript>` unless disabled).
|
||||
|
||||
- **default:** Move stylesheet links to the end of the document and insert preload meta tags in their place.
|
||||
- **"body":** Move all external stylesheet links to the end of the document.
|
||||
- **"media":** Load stylesheets asynchronously by adding `media="not x"` and removing once loaded. <kbd>JS</kbd>
|
||||
- **"swap":** Convert stylesheet links to preloads that swap to `rel="stylesheet"` once loaded ([details](https://www.filamentgroup.com/lab/load-css-simpler/#the-code)). <kbd>JS</kbd>
|
||||
- **"swap-high":** Use `<link rel="alternate stylesheet preload">` and swap to `rel="stylesheet"` once loaded ([details](http://filamentgroup.github.io/loadCSS/test/new-high.html)). <kbd>JS</kbd>
|
||||
- **"js":** Inject an asynchronous CSS loader similar to [LoadCSS](https://github.com/filamentgroup/loadCSS) and use it to load stylesheets. <kbd>JS</kbd>
|
||||
- **"js-lazy":** Like `"js"`, but the stylesheet is disabled until fully loaded.
|
||||
- **false:** Disables adding preload tags.
|
||||
|
||||
Type: (default | `"body"` | `"media"` | `"swap"` | `"swap-high"` | `"js"` | `"js-lazy"`)
|
||||
|
||||

|

> [ANSI escape codes](https://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.
|
||||
|
||||
<img src="screenshot.svg" width="900">
|
||||
|
||||
## 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.
|
||||
|
||||
The following color spaces from `color-convert` are supported:
|
||||
|
||||
- `rgb`
|
||||
- `hex`
|
||||
- `keyword`
|
||||
- `hsl`
|
||||
- `hsv`
|
||||
- `hwb`
|
||||
- `ansi`
|
||||
- `ansi256`
|
||||
|
||||
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
|
||||
```

|
||||
|
||||
## Install
|
||||
|
||||
```console
|
||||
$ npm install chalk
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
|
||||
console.log(chalk.blue('Hello world!'));
|
||||
```
|
||||
|
||||
Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
const log = console.log;
|
||||
|
||||
// Combine styled and normal strings
|
||||
log(chalk.blue('Hello') + ' World' + chalk.red('!'));
|
||||
|
||||
// Compose multiple styles using the chainable API
|
||||
log(chalk.blue.bgRed.bold('Hello world!'));
|
||||
|
||||
// Pass in multiple arguments
|
||||
log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
|
||||
|
||||
// Nest styles
|
||||
log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
|
||||
|
||||
// Nest styles of the same type even (color, underline, background)
|
||||
log(chalk.green(
|
||||
'I am a green line ' +
|
||||
chalk.blue.underline.bold('with a blue substring') +
|
||||
' that becomes green again!'
|
||||
));
|
||||
|
||||
// ES2015 template literal
|
||||
log(`
|
||||
CPU: ${chalk.red('90%')}
|
||||
RAM: ${chalk.green('40%')}
|
||||
DISK: ${chalk.yellow('70%')}
|
||||
`);
|
||||
|
||||
// ES2015 tagged template literal
|
||||
log(chalk`
|
||||
CPU: {red ${cpu.totalPercent}%}
|
||||
RAM: {green ${ram.used / ram.total * 100}%}
|
||||
DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
|
||||
`);
|
||||
|
||||
// Use RGB colors in terminal emulators that support it.
|
||||
log(chalk.keyword('orange')('Yay for orange colored text!'));
|
||||
log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
|
||||
log(chalk.hex('#DEADED').bold('Bold gray!'));
|
||||
```
|
||||
|
||||
Easily define your own themes:
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
|
||||
const error = chalk.bold.red;
|
||||
const warning = chalk.keyword('orange');
|
||||
|
||||
console.log(error('Error!'));
|
||||
console.log(warning('Warning!'));
|
||||
```
|
||||
|
||||
Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
|
||||
|
||||
```js
|
||||
const name = 'Sindre';
|
||||
console.log(chalk.green('Hello %s'), name);
|
||||
//=> 'Hello Sindre'
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### chalk.`<style>[.<style>...](string, [string...])`
|
||||
|
||||
Example: `chalk.red.bold.underline('Hello', 'world');`
|
||||
|
||||
Chain [styles](#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. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
|
||||
|
||||
Multiple arguments will be separated by space.
|
||||
|
||||
### chalk.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 Chalk consumers.
|
||||
|
||||
If you need to change this in a reusable module, create a new instance:
|
||||
|
||||
```js
|
||||
const ctx = new chalk.Instance({level: 0});
|
||||
```
|
||||
|
||||
| Level | Description |
|
||||
| :---: | :--- |
|
||||
| `0` | All colors disabled |
|
||||
| `1` | Basic color support (16 colors) |
|
||||
| `2` | 256 color support |
|
||||
| `3` | Truecolor support (16 million colors) |
|
||||
|
||||
### chalk.supportsColor
|
||||
|
||||
Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
|
||||
|
||||
Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
|
||||
|
||||
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
|
||||
|
||||
### chalk.stderr and chalk.stderr.supportsColor
|
||||
|
||||
`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
|
||||
|
||||
## Styles
|
||||
|
||||
### Modifiers
|
||||
|
||||
- `reset` - Resets the current color chain.
|
||||
- `bold` - Make text bold.
|
||||
- `dim` - Emitting only a small amount of light.
|
||||
- `italic` - Make text italic. *(Not widely supported)*
|
||||
- `underline` - Make text underline. *(Not widely supported)*
|
||||
- `inverse`- Inverse background and foreground colors.
|
||||
- `hidden` - Prints the text, but makes it invisible.
|
||||
- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
|
||||
- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
|
||||
|
||||

|
||||
- `black`

|
||||
|
||||
## Tagged template literal
|
||||
|
||||
Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
|
||||
const miles = 18;
|
||||
const calculateFeet = miles => miles * 5280;
|
||||
|
||||
console.log(chalk`
|
||||
There are {bold 5280 feet} in a mile.
|
||||
In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
|
||||
`);
|
||||
```
|
||||
|
||||
Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
|
||||
|
||||
Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
|
||||
|
||||
```js
|
||||
console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
|
||||
console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
|
||||
console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
|
||||
```
|
||||
|
||||
Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
|
||||
|
||||
All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
|
||||
|
||||
## 256 and Truecolor color support
|
||||
|
||||
Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
|
||||
|
||||
Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
|
||||
|
||||
Examples:
|
||||
|
||||
- `chalk.hex('#DEADED').underline('Hello, world!')`
|
||||
- `chalk.keyword('orange')('Some orange text')`
|
||||
- `chalk.rgb(15, 100, 204).inverse('Hello!')`
|
||||
|
||||
Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
|
||||
|
||||
- `chalk.bgHex('#DEADED').underline('Hello, world!')`
|
||||
- `chalk.bgKeyword('orange')('Some orange text')`
|
||||
- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
|
||||
|
||||
The following color models can be used:
|
||||
|
||||
- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
|
||||
- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
|
||||
- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
|
||||
- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
|
||||
- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
|
||||
- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
|
||||
- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
|
||||
- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
|
||||
|
||||
## Windows
|
||||
|
||||
If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
|
||||
|
||||
## Origin story
|
||||
|
||||
[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.
|
||||
|
||||

# color-convert
|
||||
|
||||
[](https://travis-ci.org/Qix-/color-convert)
|
||||
|
||||
Color-convert is a color conversion library for JavaScript and node.
|
||||
It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
|
||||
|
||||
```js
|
||||
var convert = require('color-convert');
|
||||
|
||||
convert.rgb.hsl(140, 200, 100); // [96, 48, 59]
|
||||
convert.keyword.rgb('blue'); // [0, 0, 255]
|
||||
|
||||
var rgbChannels = convert.rgb.channels; // 3
|
||||
var cmykChannels = convert.cmyk.channels; // 4
|
||||
var ansiChannels = convert.ansi16.channels; // 1
|
||||
```
|
||||
|
||||
# Install
|
||||
|
||||
```console
|
||||
$ npm install color-convert
|
||||
```
|
||||
|
||||
# API
|
||||
|
||||
Simply get the property of the _from_ and _to_ conversion that you're looking for.
|
||||
|
||||
All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
|
||||
|
||||
All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
|
||||
|
||||
```js
|
||||
var convert = require('color-convert');
|
||||
|
||||
// Hex to LAB
|
||||
convert.hex.lab('DEADBF'); // [ 76, 21, -2 ]
|
||||
convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
|
||||
|
||||
// RGB to CMYK
|
||||
convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ]

|
||||
|
||||
### Arrays
|
||||
All functions that accept multiple arguments also support passing an array.
|
||||
|
||||
Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
|
||||
|
||||
```js
|
||||
var convert = require('color-convert');
|
||||
|
||||
convert.rgb.hex(123, 45, 67); // '7B2D43'
|
||||
convert.rgb.hex([123, 45, 67]); // '7B2D43'
|
||||
```
|
||||
|
||||
## Routing
|
||||
|
||||
Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
|
||||
|
||||
Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
|
||||

# supports-color [](https://travis-ci.org/chalk/supports-color)
|
||||
|
||||
> Detect whether a terminal supports color
|
||||
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install supports-color
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
const supportsColor = require('supports-color');
|
||||
|
||||
if (supportsColor.stdout) {
|
||||
console.log('Terminal stdout supports color');
|
||||
}
|
||||
|
||||
if (supportsColor.stdout.has256) {
|
||||
console.log('Terminal stdout supports 256 colors');
|
||||
}
|
||||
|
||||
if (supportsColor.stderr.has16m) {
|
||||
console.log('Terminal stderr supports 16 million colors (truecolor)');
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## API
|
||||
|
||||
Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
|
||||
|
||||
The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
|
||||
|
||||
- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
|
||||
- `.level = 2` and `.has256 = true`: 256 color support
|
||||
- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
|
||||
|
||||
|
||||
## Info
|
||||
|
||||
It obeys the `--color` and `--no-color` CLI flags.
|
||||
|
||||
For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
|
||||
|
||||
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
