Valum web micro-framework

Valum is a web micro-framework entirely written in the Vala programming language.

using Valum;
using VSGI.HTTP;

var app = new Router ();

app.get ("/", (req, res) => {
    res.headers.set_content_type ("text/plain", null);
    return res.extend_utf8 ("Hello world!");
});

new Server ("org.valum.example.App", app.handle).run ();

Installation

The installation process is fully documented in the user documentation.

Features

• streaming-first API for minimal overhead with support for async I/O through GIO
• powerful routing mechanism to write expressive web services:
  • helpers and flags (i.e. Method.GET | Method.POST) for common HTTP methods
  • scoping
  • rule system supporting typed parameters, group, optional and wildcard
  • regular expression with capture extraction
  • automatic HEAD and OPTIONS
  • subrouting
  • status codes through error domains (i.e. throw new Redirection.PERMANENT ("http://example.com/");
  • filtering by composition
  • context to hold states
• middlewares for subdomains, server-sent events, content negotiation and much more
• written upon VSGI so that you can deploy using libsoup-2.4 built-in HTTP server, CGI, FastCGI or SCGI
• extensively documented at docs.valum-framework.org
