ℹ️ Note that the 'default' property has to be used when requiring this plugin, this is due to the use of Babel 6 now making ES6 compliant exports (Misunderstanding ES6 Modules, Upgrading Babel, Tears, and a Solution )
(default: true
)
Allows you to enable/disable the toc transformation of @[toc]
(default: "markdownIt-TOC"
)

Allows you to get toc contents externally by executing a callback function returning toc elements, in addition / instead of using @[toc] tag in content. Example :
markdownIt({

})
.use(markdownItTocAndAnchor, {
tocCallback: function(tocMarkdown, tocArray, tocHtml) {
console.log(tocHtml)
}
})
.render(md)
To allow callback to be more flexible, this option is also available in global markdown-it options, and in render environment. Example :
var mdIt = markdownIt({
html: true,
linkify: true,
typographer: true,
})
.use(markdownItTocAndAnchor)
....
mdIt.set({
tocCallback: function(tocMarkdown, tocArray, tocHtml) {
console.log(tocHtml)
}
})
.render(md)
var mdIt = markdownIt({
html: true,
linkify: true,
typographer: true,
})
.use(markdownItTocAndAnchor)
....
mdIt
.render(md, {
tocCallback: function(tocMarkdown, tocArray, tocHtml) {
console.log(tocHtml)
}
})
