README.md

This is pre-alpha software.

Features

  • Very fast: performance of C on the web.
  • Small binary: hello world website is <100 KB.
  • Easy to deploy: just one binary file that also includes all templates. No need to install any dependencies.
  • Templates are precompiled, all errors are visible at compilation time, not at runtime.

Lots of things are broken and not implemented yet in V and vweb.

There's no documentation yet, have a look at a simple example:

https://github.com/vlang/v/tree/master/examples/vweb/vweb_example.v

There's also the V forum: https://github.com/vlang/vorum

vorum.v contains all GET and POST actions.

pub fn (app mut App) index() {
	posts := app.find_all_posts()
	$vweb.html()
}

// TODO ['/post/:id/:title']
// TODO `fn (app App) post(id int)`
pub fn (app App) post() {
	id := app.get_post_id()
	post := app.retrieve_post(id) or {
		app.redirect('/')
		return
	}
	comments := app.find_comments(id)
	show_form := true
	$vweb.html()
}

index.html is an example of the V template language:

@for post in posts
	<div class=post>
		<a class=topic href="@post.url">@post.title</a>
		<img class=comment-img>
		<span class=nr-comments>@post.nr_comments</span>
		<span class=time>@post.time</span>
	</div>
@end

$vweb.html() compiles an HTML template into V during compilation, and embeds the resulting code in current action.

That means that the template automatically has access to that action's entire environment.

Deploying vweb apps

Everything, including HTML templates, is in one binary file. That's all you need to deploy.
