"Compressing" your html?

[Christian Gloddy]

What the easiest way to "compress" your html (aka remove unneeded whitespace) in nunjucks? Many template solutions simply make this an available setting.

As far as I know this is not possible. Nunjucks is a general purpose templating engine. You can generate HTML or anything else. Well, there is the autoescaping feature, but I think that's all.

You could parse the output and then post-process it with other library. Nevertheless it could be potentially dangerous to just remove whitespaces. For example for a "script" tag you could broke the code.

Additionally some CSS properties are sensitive to whitespaces such as "display: inline-block"

What Alberto said. Nunjucks is a string templating library; it is not
aware of HTML. This is a limitation of that.

Someone is asking for a tag to do this within the tag, it has a
(somewhat hacky) solution:

It certainly can have downsides if done inappropriately, but it's another step in getting the page to render as quickly as possible. Google's own recommendations even suggest doing so.
