wheel: A Go repository from felipesantiago

Overview

Wheel is a tool for creating and maintaining scalable and lightweight RESTful APIs. It runs through command line and generates codes (in Go Language), avoiding rework when designing the application architecture and maintenance.

Features

See full documentation of default features at http://wheel.unity26.org/features.html

Install

Go

Install Golang

Dependences

$> go get github.com/iancoleman/strcase
$> go get github.com/jinzhu/inflection

Wheel

$> go get github.com/unity26org/wheel
$> cd GOPATH/src/github.com/unity26org/wheel
$> go build -o wheel main.go 
$> sudo mv wheel /usr/bin

GOPATH is where the Go packages and sources are installed

The example above, the executable file was moved to /usr/bin. But feel free to set it up to any directory you want. Just add the path to your .profile, as you see below:

export PATH=$PATH:YOUR_DESIRED_PATH

Usage

Wheel has only two options: new to create new APIs and generate to add new functionalities to your API.

Check help for more details.

wheel --help

New API

Let's create an API for a Blog.

wheel new github.com/account_name/blog

It will output something like this:

"Go" seems installed
Checking dependences...
         ...
Generating new app...
         created: GOPATH/src/github.com/account_name/blog
         ...

Your RESTful API was successfully created!

Change to the root directory using the command line below: 
cd GOPATH/src/github.com/account_name/blog

Set up your database connection modifying the file config/database.yml

For more details call help:
go run main.go --help

Remember: GOPATH is where Go packages and sources are installed

Configure Your API

Database

Currently, Wheel has support only for Postgresql. Edit config/database.yml and set up your database connection.

Email

To connect to your email provider edit config/email.yml and set up with your send email account.

Application

Edit config/app.yml and set the following options:

Item	Definition
app_name	Your app name
app_repository	Repository name
frontend_base_url	URL to be used on your frontend
secret_key	Key to encrypt passwords on database
reset_password_expiration_seconds	After reset password, how long (in seconds) is it valid?
token_expiration_seconds	After a JWT token is generated, how long (in seconds) is it valid?
locales	List of available locales

Locales

Words and phrases for internacionalization. You can add your own locales files, but remember to add to config/app.yml configuration file first.

Running

Before running you must be sure your database schema is up to date, just run the migrate mode:

$> go run main.go -mode=migrate

Run:

$> go run main.go

Now go to http://localhost:8081 and you'll see:

{
  system_message: {
    type: "notice",
    content: "Yeah! Wheel is working!"
  }
}

New CRUD

Based on the Blog API above, let's create a new CRUD.

Don't forget to call the directory where the application were generated.

cd GOPATH/src/github.com/account_name/blog
wheel g scaffold post title:string description:text published:bool user:references
