What are custom blocks?

You can define custom language blocks inside *.vue files based on the lang attribute of the block, the block's tag name, and the rules in your webpack config. You can also use resourceQuery to match a rule against a custom block with no lang.

For example, to match against <message> custom blocks.

{
module: {
rules: [
{
resourceQuery: /blockType=message/,
loader: 'loader-to-use'
}
]
}
}
