HTML Linting

[ArmorDarks]

Okey, after all, it seems to be needed to avoid some stupid mistakes.

We will validate only build. So, it will be part of npm postbuild. We can't validate in runtime, because it can't work with templating languages. But I think that validating output will be just enough.

Local linters

• HTMLHint

  Once popular. Mostly dead now.

  It will also bring CSSLint and JSHint dependencies which are outdated those days.

• html-lint

  From creator of html-minifier

• htmllint

• htmlcs

• markuplint

API-based online validators

Those are the most accurate and up-to-date validation tools, since they will always validate against actual specs, but linting is very limited.

• w3c-validate

• html5-lint

• valimate

• w3cjs
