# Ganache Readme
|
||||
|
||||
TL:DR - To set up Ganache visit: http://truffleframework.com/ganache/
|
||||
|
||||
# Three Ways to Install Ganache
|
||||
|
||||
Ganache is provided in three libraries or distributions:
|
||||
|
||||
(1) Ganache - https://github.com/trufflesuite/ganache
|
||||
|
||||
This is a pre-built and out-of-the-box solution. Easiest to set up. It provides an interface and server shell for Ganache CLI.
|
||||
|
||||
(2) Ganache CLI - https://www.npmjs.com/package/ganache-cli
|
||||
|
||||
Ganache CLI abstracts Ganache Core and supplies the default options and arguments used.
|
||||
|
||||
(3) Ganache Core - https://www.npmjs.com/package/ganache-core
|
||||
|
||||
Basically, only use Ganache Core if you need to build a totally customized option.
|
||||
|
||||
# Use
|
||||
|
||||
The default port is *8545* on *localhost*

# Using Truffle
|
||||
|
||||
Basic Truffle walkthrough readme.
|
||||
|
||||
See also: http://truffleframework.com/docs/
|
||||
|
||||
# Bash
|
||||
|
||||
Truffle install
|
||||
|
||||
```bash
|
||||
$ npm install truffle -g
|
||||
$ truffle version
|
||||
```
|
||||
|
||||
Truffle commands:
|
||||
|
||||
```bash
|
||||
$ truffle init
|
||||
$ truffle compile
|
||||
$ truffle migrate
|
||||
$ truffle test
|
||||
```
|
||||
|
||||
# Directory Structure
|
||||
|
||||
The command `$ truffle init` will create a directory structure in the specified root according to the following:
|
||||
|
||||
```
|
||||
root -|
|
||||
|-build (Compiled Solc JSON Output Dir)
|
||||
|-contracts (Solc Contracts to be Compiled and Migrated)
|
||||
|-migrations (Specify the Order and Dependencies of Contracts to Be Deployed)
|
||||
|-test (Truffle Tests)
|
||||
```
|
||||
|
||||
# Compile
|
||||
|
||||
Truffle will compile the smart contracts and expose their **JSON ABI's for use with Web3.js** or **Binary ABI's for use with Web3J**.
|
||||
|
||||
# Migration
|
||||
|
||||
Truffle will let you deploy your Solc contracts directly to a blockchin of your choice.
