shipped llv8call 0.07

Sep 28, 2008

The killer feature of this version is "shttpd support"(http://shttpd.sourceforge.net/).

Run the httpd by JavaScript!

v8ext.LoadBinary("org.coderepos.shttpd");
var SHTTPD = org.coderepos.shttpd.SHTTPD;
var httpd = new SHTTPD(8080);
httpd.RegisterURI("/", function (r) {
   r.Print("HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n");
   r.Print("<html><body>Hello, v8 world</body></html>");
   r.SetFlags(SHTTPD.END_OF_OUTPUT);
});
httpd.StartLoop();

Architecture of llv8call

Sep 28, 2008

llv8call is a good solution for server side javascript.It is composed of three parts.

1. Core

builtin functions
ARGV support
ENV support
better interactive mode based on libreadline

2.v8ext
v8ext is extension library library for v8. This module makes "easy to extend your application, uses v8".
This module provides 2 methods and 1 property

v8ext.LoadScript()
v8ext.LoadBinary()
v8ext.LibraryPath

This library is easy to use =)
3.extension libraries
llv8call respects "batteries included" style.
current version provides:

sqlite3
libfcgi
nspr(NetScape Portable Runtime), this module exports File, TCPSocket, UDPSocket, Process Management, Dir, etc.
libmemcached
curl

I've start new project named llv8call.
llv8call is an library for call OS from v8.

http://code.google.com/p/llv8call/

You can easy to inject a lot of classes by follow code:

v8::HandleScope handle_scope;
v8::Handle global = v8::ObjectTemplate::New();
v8::Handle context = v8::Context::New(NULL, global);
v8::Context::Scope context_scope(context);
LLV8::Init(argc, argv, context->Global());

currently, llv8call supports follow things. This is based on
NSPR(NetScape Portable Runtime).

* File()
* Dir()
* System vars
* STDIN/STDOUT/STDERR
* Process Management
* Load Dynamic Library
* require()
* TCPSocket

regards.

libv8 + libfastcgi = Server Side JavaScript

I've wrote fcgi-v8, yesterday.

You can write FastCGI server in JavaScript very easily!!

You can write both of the server side and client side, in JavaScript. This makes less study, less stress.

follow is the example code.

#!/home/tokuhiro/project/v8/llv8call
var count = 0;
while (fcgi_accept() >= 0) {
    print("Content-type: text/html¥r¥n¥r¥n", ++count, "¥nQuery: ", getenv("QUERY_STRING"));
}
