npm install kru-node-markdown

Basic Usage

The markdown() function exported by kru-node-markdown can take data in various formats.

Array: If you provide a single-dimensional array, it will be treated as a single row of data. If you provide a two-dimensional array, each sub-array will be treated as an individual row of data.

Object: If you provide an object, you should set the data property to an array of data. This document outlines other properties you can provide to customize the output.

import markdown from 'kru-node-markdown';

const md = markdown(
	[
		['Thor', 'Ironman', 'Loki'],
		['Blackwidow', 'Hulk', 'Hawkeye']
	]
);

console.log(md);

// | Column 1   | Column 2 | Column 3 |
// | ---------- | -------- | -------- |
// | Thor       | Ironman  | Loki     |
// | Blackwidow | Hulk     | Hawkeye  |

Custom Headers

By default, headers will be automatically generated for the table. If you want to specify your own headers, you can do so by passing an array of strings as options.headers.

Note: If you don't provide enough headers to cover all columns, the remaining headers will be automatically generated.

Note: If you provide more headers than columns, the additionally provided headers will be included and rows will be padded with empty cells.

const md = markdown({
	headers: ['Header A', 'Header B', 'Header C'],
	data: [
		['Harry', 'Ron', 'Ginny'],
		['Luna', 'Hagrid', 'Dobby']
	]
});

console.log(md);

// | Header A | Header B | Header C |
// | -------- | -------- | -------- |
// | Harry    | Ron      | Ginny    |
// | Luna     | Hagrid   | Dobby    |

Custom Header Prefix

If you don't want to specify your own headers, but you want to customize the prefix used to generate the headers, you can do so by passing a string as options.headerPrefix.

const md = markdown({
	headerPrefix: 'Foo ',
	data: [
		['Harry', 'Ron', 'Ginny'],
		['Luna', 'Hagrid', 'Dobby']
	]
});

console.log(md);

// | Foo 1 | Foo 2  | Foo 3 |
// | ----- | -----  | ----- |
// | Harry | Ron    | Ginny |
// | Luna  | Hagrid | Dobby |

Minimal Output

By default, the markdown output is formatted with padding to create human readable tables. If you want to output the table with minimal formatting, you can do so by passing options.minimal as true.

const md = markdown({
	minimalOutput: true,
	data: [
		['Harry', 'Ron', 'Ginny'],
		['Luna', 'Hagrid', 'Dobby']
	]
});

console.log(md);

// |Column 1|Column 2|Column 3|
// |---|---|---|
// |Harry|Ron|Ginny|
// |Luna|Hagrid|Dobby|

Content Alignment

To align the content of fields, you can provide options.alignment which can be a string (left, center, or right) or an array of strings. If you provide a string, it will be applied to all columns. If you provide an array, each string will be applied to the corresponding column.

Note: Only the first letter is used to determine the alignment, allowing for a short-hand syntax of l, c, or r.

const md = markdown({
	alignment: ['l', 'c', 'r'],
	data: [
		['Harry', 'Ron', 'Ginny'],
		['Luna', 'Hagrid', 'Dobby']
	];
});

console.log(md);

// | Column 1 | Column 2 | Column 3 |
// | :------- | :------: | -------: |
// | Harry    |  Ron     | Ginny    |
// | Luna     |  Hagrid  | Dobby    |

Miscellaneous Options

{
	// The character(s) to use to separate rows.
	lineSeparator: '\r\n',
}
