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.
```v ignore
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.vweb.redirect('/')
return
}
comments := app.find_comments(id)
show_form := true
$vweb.html()
}
```
`index.html` is an example of the V template language:
```html
@for post in posts
<div class=post>
<a class=topic href="@post.url">@post.title</a>
<img class=comment-img>
<span class=nr-comments>@post.nr_comments</span>
<span class=time>@post.time</span>
</div>
@end
```
`$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.
