🎨 Use a color theme for your code's terminal output.
A color theme enforces consistency and simplifies updating styles.
Your code specifies the default theme: [styles](#available-styles) and
categories associated to them. Users
[can then optionally override it](#user-theme).
This supports [256 colors, Truecolor](#available-styles) and terminal colors
detection, thanks to [`chalk`](https://github.com/chalk/chalk).
# Hire me
Please
[reach out](https://www.linkedin.com/feed/update/urn:li:activity:7117265228068716545/)
if you're looking for a Node.js API or CLI engineer (11 years of experience).
Most recently I have been [Netlify Build](https://github.com/netlify/build)'s
and [Netlify Plugins](https://www.netlify.com/products/build/plugins/)'
technical lead for 2.5 years. I am available for full-time remote positions.
# Example
```js
import terminalTheme from 'terminal-theme'
// Any category/key is possible
const defaultTheme = {
error: 'red bold',
success: 'green',
title: 'white bold',
// Truecolor is supported
subtitle: 'rgb-150-100-100',
}
const { error, success, title, subtitle } = await terminalTheme(defaultTheme)
console.log(success('example')) // Print in green color
```
# User theme
Users can override the `defaultTheme` by creating a `terminal-theme.yml` in the
current or any parent directory.
```yml
error: yellow bold
success: cyan
```
Or programmatically:
```js
const { error, success, title, subtitle } = await terminalTheme({
...defaultTheme,
...userTheme,
})
console.log(success('example'))
```
# Install
```
npm install terminal-theme
```
This package works in Node.js >=18.18.0.
This is an ES module. It must be loaded using
[an `import` or `import()` statement](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c),
not `require()`. If TypeScript is used, it must be configured to
[output ES modules](https://www.typescriptlang.org/docs/handbook/esm-node.html),
not CommonJS.
# API
## terminalTheme(defaultTheme, options?)
`defaultTheme`: `object`\
`options`: `object`\
_Return value_: `Promise`
### defaultTheme
The `defaultTheme` argument is an object where each:
- Key is a category with consistent styles. Examples include `error`, `success`,
`link`, `header`, etc.
- Value is a space-separated list of [styles](#available-styles). Some styles
require dash-separated arguments.
```js
const defaultTheme = {
// Single style, without arguments
success: 'green',
// Single style, with arguments
warning: 'rgb-226-126-26',
// Multiple styles
error: 'red bold',
}
```
### Return value
The return value is a promise resolving to an object where each:
- Key is a category defined in the theme.
- Value is a function applying [styles](#available-styles) to a string.
```js
const { error, success } = await terminalTheme({
error: 'red',
success: 'green',
})
console.log(success('example'))
```
### options
#### colors
_Type_: `boolean`\
_Default_: `undefined`
Whether colors should be enabled/disabled, regardless of terminal support.
Colors support is automatically detected, so this is only meant to override that
default behavior.
#### stream
_Type_:
[`Stream`](https://nodejs.org/api/stream.html#stream_class_stream_writable)\
_Default_: [`process.stdout`](https://nodejs.org/api/process.html#process_process_stdout)
Stream used to detect colors support. This should be the file or terminal where
the colors are output.
#### cwd
_Type_: `string`\
_Default_: `process.cwd()`
Current directory. Used when [looking for `terminal-theme.yml`](#user-theme).
