## Install

**Yarn**

```bash
yarn add -dev markdown-it-chain
```

**npm**

```bash
npm install --save-dev markdown-it-chain
```

## Getting Started

```js
// Require the markdown-it-chain module. This module exports a single
// constructor function for creating a configuration API.
const Config = require('markdown-it-chain')

// Instantiate the configuration with a new API
const config = new Config()

// Make configuration changes using the chain API.
// Every API call tracks a change to the stored configuration.
config
  // Interact with 'options' in new MarkdownIt
  // Ref: https://markdown-it.github.io/markdown-it/#MarkdownIt.new
  .options
    .html(true) // equal to .set('html', true)
    .linkify(true)
    .end()

  // Interact with 'plugins'
  .plugin('toc')
    // The first parameter is the plugin module, which may be a function
    // while the second parameter is an array of parameters accepted by the plugin.
    .use(require('markdown-it-table-of-contents'), [{
      includeLevel: [2, 3]
    }])
    // Move up one level, like .end() in jQuery.
    .end()

  .plugin('anchor')
    .use(require('markdown-it-anchor'), [{
      permalink: true,
      permalinkBefore: true,
      permalinkSymbol: '$'
    }])
    // Apply this plugin before toc.
    .before('toc')

// Create a markdown-it instance using the above configuration
const md = config.toMd()
md.render('[[TOC]] \n # h1 \n ## h2 \n ## h3 ')
```

## Worth Reading

In order to ensure the consistency of the chained API world, `markdown-it-chain` is developed directly on the basis of [webpack-chain](https://github.com/neutrinojs/webpack-chain) and ensures that the usage is completely consistent.

Here are some things worth reading that come from `webpack-chain`:

- [ChainedMap](https://github.com/neutrinojs/webpack-chain#chainedmap)
- [Config plugins](https://github.com/neutrinojs/webpack-chain#config-plugins)
