mdast utility to assert trees.

Install

npm:

npm install mdast-util-assert

Use

var assert = require('mdast-util-assert')

assert({type: 'root', children: []})
assert({type: 'break'})
assert({type: 'listItem', checked: true, children: []})
// All OK.

assert({children: []})

API

assert(node)

Assert that tree is a valid mdast node. If tree is a parent, all children will be asserted as well.

The assert.parent, assert.text, assert.void, and assert.wrap methods from unist-util-assert are also included.

Security

Use of mdast-util-assert does not involve hast so there are no openings for cross-site scripting (XSS) attacks.
