# Colorette [![](https://img.shields.io/npm/v/colorette.svg?label=&color=0080ff)](https://www.npmjs.org/package/colorette)
> Color your terminal using pure idiomatic JavaScript.
Colorette is a Node.js library for embellishing your CLI tools with colors and styles using [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code).
- ~1.5x faster than alternatives ([run the benchmarks](#run-the-benchmarks)).
- No wonky prototype-based method chains.
- Automatic color support detection.
- ~80 LOC and no dependencies.
- [`NO_COLOR`](https://no-color.org) friendly.
## Quickstart
```console
npm i colorette
```
Import the [styles](#styles) you need. [Here](#supported-styles)'s the list of styles you can use.
```js
const { red, blue, bold } = require("colorette")
```
Wrap your strings in one or more styles to produce the finish you're looking for.
```js
console.log(bold(blue("Engage!")))
```
Mix it with [template literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) to interpolate variables, expressions and create multi-line strings easily.
```js
console.log(`
Beets are ${red("red")},
Plums are ${blue("blue")},
${bold("Colorette!")}.
`)
```
Using `console.log`'s [string substitution](https://nodejs.org/api/console.html#console_console_log_data_args) can be useful too.
```js
console.log(bold("Total: $%f"), 1.99)
```
You can also nest styles without breaking existing escape codes.
```js
console.log(red(`Red Shirt ${blue("Blue Shirt")} Red Shirt`))
```
Feeling adventurous? Try the [pipeline operator](https://github.com/tc39/proposal-pipeline-operator).
```js
console.log("Make it so!" |> bold |> blue)
```
## Supported styles
Colorette supports the standard and bright color variations out-of-the-box. See [this issue](https://github.com/jorgebucaran/colorette/issues/27) if you were looking for TrueColor support.
| Colors | Background Colors | Bright Colors | Bright Background Colors | Modifiers |
| ------- | ----------------- | ------------- | ------------------------ | ----------------- |
| black | bgBlack | blackBright | bgBlackBright | dim |

## API
### <code><i>style</i>(string)</code>
Returns a string wrapped in the corresponding ANSI escape codes.
```js
red("Red Alert") //=> \u001b[31mRed Alert\u001b[39m
```
### `options.enabled`
Color will be enabled if your terminal supports it, `FORCE_COLOR` is defined in [`process.env`](https://nodejs.org/dist/latest-v8.x/docs/api/process.html#process_process_env) and if `NO_COLOR` isn't, but you can always override it if you want.
```js
const { options } = require("colorette")
options.enabled = false
```
