GoCore

GoCore

A Golang solution of tools for building a full stack web application.

Goals of the Project

Below are some targeted goals:

• Http & Https Redirection & HTTP 2.0 with Golang 1.8 and gin-gonic/gin
• Extension packages for common functions including:
  • File IO Management & Manipulation
  • Zip File Compression & Decompression

• Database extensions and drivers for the following:
  • Supported databases:
    • MongoDB
    • BoltDB
  • Create SQL Schema (DDL) from JSON Configuration.
  • Create Golang ORM packages for RDBMS Transactions & Queries.

Getting Started

Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install MongoDB

brew tap mongodb/brew

brew install mongodb-community

brew services start mongodb/brew/mongodb-community

Install NPM and Node JS

https://nodejs.org/en/download/

Install Webpack

npm install --global webpack@v2.6.1

Install Golang

Setup

Edit sudoers

sudo vim /etc/sudoers

yourusername ALL = NOPASSWD: ALL

Add your gopath bin directory to your PATH and set NODE_ENV=development

vim ~/.bash_profile

Add lines export PATH="$PATH:/Users/davidrenne/go/bin" export NODE_ENV=development

Source it:

source ~/.bash_profile

Get GoCore

1. To start a new project with go modules (1.13) GoCore run the following steps in a new console window.

   go mod init github.com/your_example/repo_project

   go get github.com/DanielRenne/GoCore

1.5. To start a new project with a version prior to go modules.

`go get github.com/DanielRenne/GoCore/...`

Add to your Operating Systems Path the ~/go/bin directory

Build GoCore App

1. A sample project generator is available to build a GoCore project.

   go install github.com/DanielRenne/GoCore/core/goCoreCreateApp

   And install the binary for fetching the project template files

   go install github.com/DanielRenne/GoCore/getAppTemplate

Then run

goCoreCreateApp

Follow the prompts to generate your app and it will copy the templates found in GoCore/tools/appFiles into your project directory github.com/username/appName. Note you probably should install nodejs, npm and nvm before generating an app.

GoCore has built in functions to read json configuration files to generate SQL Tables, indexes, primary & foreign keys, NOSQL Collections & Buckets, auto-generated Golang model code files, auto-generated REST web api code files, and swagger.io schema files application. See BuildCore Readme for details.

Run Your GoCore App

1. Run the following to start your app

   bash bin/start_app

Open a web browser to: http://127.0.0.1:8080

Login as admin/admin and setup application roles etc. More documentation to come later on application specific setup.

How to build your own web project in GoCore

See Application Settings within docs for information on what webConfig.json allows for.

IMPORTANT NOTE for HTTPS (TLS) Security

GoCore comes default with an open ssl generated Cert and PEM files that are NOT secret as they are available via the open source repository. Make sure you replace both these files located in the keys directory. To do this we recommend in Linux running the following command and copying the output files to the keys directory. Alternatively cert and pem files generated by a valid Certificate Authority like GoDaddy or Verisign when you reach production with an online domain.

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout key.pem -out cert.pem

NOTE: We also recommend NOT to store your secret key files in source control. We recommend ignoring the keys directory for source control.

NOTE: key files are ingored when running getCore as to not overwrite your keys.

Building a Database Model with SQLite3

####NOTE: Because SQLite3 requires gcc externally we separated the driver for compiling reasons. Windows users we recommend installing gcc as a prerequisite for the sqlite3 golang module to compile via tdb-gcc. Be sure to install 64 bit for 64 bit machines.

####More SQLite tools to verify your data in Windows SQLite Studio

To create a SQLite3 Database schema and model package for your application run the following:

go install github.com/DanielRenne/GoCore/buildCoreLite

Then run

buildCoreLite
