Arasu : A Lightning Fast Web Framework

Note: arasu development only work on dart enabled browsers like dartium or dart enabled chrome browser.

Arasu is a Next Generation Full Stack Web framework written on Go language & Dart language.

Features

lightning fast, because of golang and dartlang
use RDBMS(mysql is default) and BIGDATA(hbase is default) for serverside store
use IndexedDB and Angular Dart for clientside store,clientside framework
use TDD defaultly supported by golang and dartlang
use BDD with selenium and Spinach (this is not yet started github.com/arasuresearch/arasu/bdd)
automatic build system.

Installation

Install Golang then add golang binary into system PATH.

export GOROOT="go-installation-directory"

for example if you extracted downloaded go.tag.gz into "/home/user/go" then

export GOROOT=/home/user/go

export GOPATH="any-directory-where-you-want-to-keep-go-libraries"

for example you can use

export GOPATH=/home/user/gopath

add both bin into system PATH by

export PATH=$GOROOT/bin:$GOPATH/bin:$PATH

verify the sucessfull installation by

~$ go version
go version go1.4 linux/amd64

Install Dartlang(Dart SDK) then add DART_HOME & dart-sdk binary into system PATH.

for example if you extracted downloaded dart.tag.gz into "/home/user/dart" then add

export DART_HOME=/home/user/dart
export PATH=$DART_HOME/dart-sdk/bin:$PATH

verify the sucessfull installation by

~$ dart --version
Dart VM version: 1.8.3 (Mon Dec  1 08:42:49 2014) on "linux_x64"

Install Mysql then add mysql binary into system PATH and verify the sucessfull installation by

~$ mysql --version
mysql  Ver 14.14 Distrib 5.5.37, for debian-linux-gnu (x86_64) using readline 6.2

Install Hbase then add hbase binary into system PATH.

set HBASE_HOME , JAVA_HOME and add these bin into system $PATH

export HBASE_HOME=/hbase/extracted/folder
export JAVA_HOME=/java/extracted_or_installed/folder

export PATH=$HBASE_HOME/bin:$JAVA_HOME/bin:$PATH

verify the sucessfull installation by

~$ hbase version
//some valid output

finally

Install Arasu Framework by

~$ go get github.com/arasuresearch/arasu

Creating a New Arasu Project

Part 1

Creating scaffold for relational Database Management System aka RDBMS (mysql)

~$ arasu new demo
~$ cd demo
~$ arasu dstore create
~$ arasu generate scaffold Admin name password:string age:integer dob:timestamp sex:bool
~$ arasu dstore migrate

Now start the server:

~$ arasu serve

// you will get output like "You don't have a lockfile, so we need to generate that:" by // Dart Pub Manager ,this will take few more seconds (this will occur at first time only).

after successfull start....

now visit "http://localhost:4000/" or "http://localhost:4000/#/admins" on Dartium

~$ $DART_HOME/chromium/chrome --user-data-dir=$HOME/.config/google-dart http://localhost:4000/#/admins

open dartium dev tools settings and disable cache by checking "Disable cache (while DevTools is open)"

for ubuntu users (tested only on ubuntu 14.10) if you get error like

dart/chromium/chrome: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory

then check "/lib/x86_64-linux-gnu" folder for latest libudev and link it to

sudo ln -s /lib/x86_64-linux-gnu/libudev.so.1.4.0 /usr/lib/libudev.so.0

There you can play !!!

Part 2

Note : for normal application you can use any RDBMS like mysql as we did in the above part 1. this part 2 is using BigData(hbase) as database. please use hbase with caution (read more at Hbase)

Creating scaffold for BigData (hbase)

stop the arasu server by pressing CTRL + C

open another new terminal and start bigdata...

~$ start-hbase.sh
~$ hbase thrift start

leave this terminal to run thrift deamon. come back to old terminal then

~$ arasu dstore create --dstore bigdata

this will result in failure

unfortunately Hbase thrift V1 Binary server is not supporting to create database through API Calls so we have to create it manually . to do that

~$ hbase shell
> create_namespace 'demo_development'
> quit

close hbase shell , then

~$ arasu generate scaffold User Profile:{FirstName:String,LastName:String,Age:int,Dob:DateTime} Contact:{Phone:String,Email:String} --dstore bigdata
~$ arasu dstore migrate --dstore bigdata

Now start the server:

~$ arasu serve

now visit

~$ $DART_HOME/chromium/chrome --user-data-dir=$HOME/.config/google-dart http://localhost:4000/#/users

there you are !!!!!!!! enjoyyyy!!!!!!
