# Deprecated
**DEPRECATED:** Use
**[`picocolors`](https://github.com/alexeyraspopov/picocolors)** instead.
It is 3 times smaller and 50% faster.
The space in node_modules including sub-dependencies:
```diff
- nanocolors 16 kB
+ picocolors 7 kB
```
Library loading time:
```diff
- nanocolors 0.885 ms
+ picocolors 0.470 ms
```
Benchmark for complex use cases:
```diff
- nanocolors 1,088,193 ops/sec
+ picocolors 1,772,265 ops/sec
```
## Old docs
A tiny and fast Node.js library to ANSI colors to terminal output.
```js
import { green, bold } from 'nanocolors'
console.log(
green(`Task ${bold('1')} was finished`)
)
```

## Replacing `chalk`
1. Replace import and use named exports:
```diff
- import chalk from 'chalk'
+ import { red, bold } from 'nanocolors'
```
2. Unprefix calls:
```diff
- chalk.red(text)
+ red(text)
```
3. Replace chains to nested calls:
```diff
- chalk.red.bold(text)
+ red(bold(text))
```
4. If you used template tag, then use
the [`nanocolors-template`](https://github.com/usmanyunusov/nanocolors-template):
```diff
- import chalk from 'chalk'
+ import { colorize } from 'nanocolors-template'
- chalk.yellow.bold`yellow {red ${"text"}}`
+ colorize`{yellow.bold yellow {red ${"text"}}}`
```

## API
### Individual Colors
Nano Colors exports functions:
| Colors | Background Colors | Modifiers |
| --------- | ------------------- | ----------------- |
| `black` | `bgBlack` | dim |
| `red` | `bgRed` | **bold** |
| `green` | `bgGreen` | hidden |
| `yellow` | `bgYellow` | _italic_ |
| `blue` | `bgBlue` | underline |
| `magenta` | `bgMagenta` | ~~strikethrough~~ |
| `cyan` | `bgCyan` | reset |
| `white` | `bgWhite` | |
| `gray` | | |
Functions are not chainable. You need to wrap it inside each other:
```js
import { black, bgYellow } from 'nanocolors'
console.log(bgYellow(black(' WARN ')))
```
Functions will use colors only if Nano Colors auto-detect that current
environment supports colors.
You can get support level in `isColorSupported`:
```js
import { isColorSupported } from 'nanocolors'
if (isColorSupported) {
console.log('With colors')
}
```
### Conditional Support
You can manually switch colors on/off and override color support auto-detection:
```js
import { createColors } from 'nanocolors'
const { red } = createColors(options.enableColors)
```
On `undefined` argument, `createColors` will use value
from color support auto-detection.
