NAME

Nephia - Mini WAF

SYNOPSIS

### Get started the Nephia!
$ nephia-setup MyApp

### And, plackup it!
$ cd myapp
$ plackup

DESCRIPTION

Nephia is a mini web-application framework.

This software is still alpha quality. Its API may change without notice.

MOUNT A CONTROLLER

Use "path" function as following in lib/MyApp.pm .

First argument is path for mount a controller. This must be string.

Second argument is controller-logic. This must be code-reference.

In controller-logic, you may get Plack::Request object as first-argument, and controller-logic must return response-value as hash-reference or Nephia::Response object.

Basic controller - Makes JSON response

Look this examples.

path '/foobar' => sub {
    my ( $req ) = @_;
    # Yet another syntax is following.
    # my $req = req;

    return {
        name => 'MyApp',
        query => param('q'),
    };
};

This controller outputs response-value as JSON, and will be mounted on "/foobar".

Use templates - Render with Text::MicroTemplate

path '/' => sub {
    return {
        template => 'index.html',
        title => 'Welcome to my homepage!',
    };
};

Attention to "template" attribute. If you specified it, controller searches template file from view-directory and render it.

If you use multibyte-string in response, please remember use utf8 and, you may specify character-set as like as following.

use utf8; ### <- very important
path '/' => sub {
    return {
        template => 'mytemplate.tx',
        title => 'わたしのホォムペェジへよおこそ！',
        charset => 'Shift_JIS',
    };
};

If you not specified charset, it will be 'UTF-8'.

Makes response - Using "res" function

path '/my-javascript' => sub {
    return res {
        content_type( 'text/javascript' );
        body( 'alert("Oreore!");' );
    };
};

"res" function returns Nephia::Response object with some DSL.

You may specify code-reference that's passed to res() returns some value. These values are passed into arrayref that is as plack response.

path '/some/path' => sub {
    res { ( 200, ['text/html; charset=utf8'], ['Wooootheee!!!'] ) };
};

And, you can write like following.

path '/cond/sample' => sub {
    return res { 404 } unless param('q');
    return res { ( 200, [], ['you say '. param('q')] ) };
};

Commands supported in "res" function are following.

status
headers
body
content_type
content_length
content_encoding
redirect
cookies

Please see Plack::Response's documentation for more detail.

Limitation by request method - Using (get|post|put|del) function

### catch request that contains get-method
get '/foo' => sub { ... };

### post-method is following too.
post '/bar' => sub { ... };

### put-method and delete-method are too.
put '/baz' => sub { ... };
del '/hoge' => sub { ... };

How to use routing with Router::Simple style matching-pattern and capture it - Using path_param function

post '/item/{id:[0-9]+}' => sub {
    my $item_id = path_param->{id}; # get param named "id" from path
    ...
};

Submapping to other applications that use Nephia

It's easy. Call "path" function by package instead of a coderef.

package MyApp;
use Nephia;

path '/childapp' => 'ChildApp';

in MyApp/ChildApp.pm:

package MyApp::ChildApp;
use Nephia;

get '/message' => sub {
    message => 'this is child app!'
};

This controller mapped to "/childapp/message".

Can use "+" prefix in package name. This syntax feature is to use absolute package name.

Example:

package MyApp;

path '/otherapp' => '+OtherApp';

"/otherapp" connect to "OtherApp".

Support to multiple path to SubApp.

Example:

package MyApp;

path '/subapp1' => 'SubApp';
path '/subapp2' => 'SubApp';

The MyApp::SubApp connected to "/subapp1" and "/subapp2".

If you want to set cookie, use "set_cookie" command.

path '/somepath' => sub {
    set_cookie cookiename => 'cookievalue';
    return +{ ... };
};

And, getting a cookie value, use "cookie" command.

path '/anypath' => sub {
    my $cookie_value = cookie 'cookiename';
    return +{ ... };
};

USING CONFIG

First, see app.psgi that generated by nephia-setup.

use strict;
use warnings;
use FindBin;

use lib ("$FindBin::Bin/lib", "$FindBin::Bin/extlib/lib/perl5");
use MyApp;
MyApp->run;

You may define config with run method as like as following.

MyApp->run(
  attr1   => 'value',
  logpath => '/path/to/log',
  ...
);

And, you can access to these config in your application as following.

path '/foo/bar' => sub {
  my $config = config;
};

STATIC CONTENTS ( like as image, javascript ... )

You can look static-files that is into root directory via HTTP.

PLUGINS

You may use plugins for Nephia.

See Nephia::Plugin for more detail about plugin.

FUNCTIONS

path $path, $coderef_as_controller;

Mount controller on specified path.

get post put del

Usage equal as path(). But these functions specifies limitation for HTTP request-method.

req

Return Plack::Request object. You can call this function in code-reference that is argument of path().

res $coderef

Return Nephia::Response object with some DSL.

param

Return query-parameters that contains in path as hashref. (As like as "req->parameters")

param $param_name

Return specified query-parameter. (As like as "req->param($param_name)")

path_param

Return parameters as hashref that captured by Router::Simple.

path_param $keyname

Return specified parameter that captured by Router::Simple.

nip / nip $keyname

Alias for path_param.

NOTE: Need more clever name for this function.

config

Return config as hashref.

base_dir

Return the absolute path to root of application.

Get specified cookie value.

Set value into specified cookie.

nephia_plugins @plugins

Load specified Nephia plugins.
