Ark Taco Shop

Requirements

Make sure you’ve got a recent version of:

• Node.js - We suggest using NVM to handle it
• Docker and Docker-Compose - We use docker to run our database. You can skip it if you have Postgres installed locally.
• Yarn - Fast, Reliable, and secure dependency management.
• Lerna - A tool for managing JavaScript projects with multiple packages.
• ARK Desktop Wallet - ARK Desktop Wallets to see the transactions

Installation

To begin, create a root folder to contain the ark core and the ark-taco-shop components.

cd ~
git clone https://github.com/ArkEcosystem/core.git
cd core
git fetch https://github.com/arkecosystem/core 2.5.1:2.5.1
git checkout 2.5.1
yarn setup
yarn docker ark

Database

We will use ARK core's docker files to make it easier to create/manage the database. If you prefer to use postgres directly, skip the section below and create a new database called ark_testnet.

Creating database using docker

cd ~/core/docker/development/testnet
docker-compose up -d postgres

If you need to remove it, you can run the following:

cd ~/core/docker/development/testnet
docker-compose down -v

Ark Taco Shop Plugins

Clone the MLH/localhost-ark repository:

cd ~/core/plugins
git clone https://github.com/MLH/localhost-ark

This repository contains two different plugins:

• ark-taco-shop-api - the server plugin, that provides backend capabilities and integrates with ARK's blockchain
• ark-taco-shop - the client plugin, that provides frontend capabilities and integrates with ark-taco-shop-api

The server - Ark Taco Shop Api

To install the server, copy the ark-taco-shop-api plugin to the ARK core's plugins folder:

cd ~/core/plugins
mv ./localhost-ark/ark-taco-shop-api ./

Configuration

We will be using testnet as a local network to run ARK. To configure it, modify the file core/packages/core/bin/config/testnet/plugins.js and copy the contents of the configuration object from the file localhost-ark/ark-taco-shop-api/src/defaults.ts, and append it to the plugins.js file, like showed below:

{
  '@arkecosystem/core-event-emitter': {},
  '@arkecosystem/core-config': {},
  ...
  },
  '@mlh/ark-taco-shop-api': {
    enabled: process.env.ARK_INVENTORY_API_ENABLED || true,
    server: {
        enabled: process.env.ARK_INVENTORY_API_SERVER_ENABLED || true,
        host: process.env.ARK_INVENTORY_API_SERVER_HOST || "0.0.0.0",
        port: process.env.ARK_INVENTORY_API_SERVER_PORT || 5000,
    },
  }
}

Make sure to change the database properties to use the database configs you have set up before.

Install dependencies

cd ~/core
yarn setup

Run the application

cd ~/core/packages/core
yarn full:testnet

The output may be a bit verbose, but you should see the message ark-taco-shop-api available and listening on http://0.0.0.0:5000 in it.

To test it, make sure the url http://0.0.0.0:5000/api/taco/products returns a valid json, like the one below:

{
  "results": [],
  "totalCount": 0
}

Add products to inventory

Access http://0.0.0.0:5000/inventory and use the form to submit a csv. It expects the following format:

PRODUCT_CODE1,PRODUCT_NAME1,PRODUCT_DESCRIPTION,PRODUCT_IMAGE_URL,PRODUCT_PRICE_IN_DARK,QUANTITY
PRODUCT_CODE2,PRODUCT_NAME2,PRODUCT_DESCRIPTION,PRODUCT_IMAGE_URL,PRODUCT_PRICE_IN_DARK,QUANTITY
PRODUCT_CODE3,PRODUCT_NAME3,PRODUCT_DESCRIPTION,PRODUCT_IMAGE_URL,PRODUCT_PRICE_IN_DARK,QUANTITY
PRODUCT_CODE4,PRODUCT_NAME4,PRODUCT_DESCRIPTION,PRODUCT_IMAGE_URL,PRODUCT_PRICE_IN_DARK,QUANTITY
PRODUCT_CODE5,PRODUCT_NAME5,PRODUCT_DESCRIPTION,PRODUCT_IMAGE_URL,PRODUCT_PRICE_IN_DARK,QUANTITY
PRODUCT_CODE6,PRODUCT_NAME6,PRODUCT_DESCRIPTION,PRODUCT_IMAGE_URL,PRODUCT_PRICE_IN_DARK,QUANTITY

There is an example file: localhost-ark/ark-taco-shop-api/inventory-file-example.csv

The client - Ark Taco Shop

To install the client, copy the ark-taco-shop plugin to the ARK core's plugins folder:

cd ~/core/plugins
mv ./localhost-ark/ark-taco-shop ./

Configuration

We will be using testnet as a local network to run ARK. To configure it, modify the file core/packages/core/lib/config/testnet/plugins.js and copy the configuration object from of the file localhost-ark/ark-taco-shop/src/defaults.ts, and add it like showed below:

{
  '@arkecosystem/core-event-emitter': {},
  '@arkecosystem/core-config': {},
  ...
  },
  '@mlh/ark-taco-shop': {
    enabled: process.env.ARK_TACO_SHOP_ENABLED || true,
    server: {
        enabled: process.env.ARK_TACO_SHOP_SERVER_ENABLED || true,
        host: process.env.ARK_TACO_SHOP_SERVER_HOST || "0.0.0.0",
        port: process.env.ARK_TACO_SHOP_SERVER_PORT || 3000,
    },
    inventoryApi: {
        sender: process.env.ARK_TACO_SHOP_INVENTORY_SENDER_ADDRESS || "AJjv7WztjJNYHrLAeveG5NgHWp6699ZJwD",
        passphrase:
            process.env.ARK_TACO_SHOP_INVENTORY_SENDER_PASSPHRASE ||
            "decide rhythm oyster lady they merry betray jelly coyote solve episode then",
        recipient: process.env.ARK_TACO_SHOP_INVENTORY_RECIPIENT || "ANBkoGqWeTSiaEVgVzSKZd3jS7UWzv9PSo",
        uri: process.env.ARK_TACO_SHOP_INVENTORY_API_URL || "http://0.0.0.0:5000/api",
    },
}

Notes:

• Make sure to change the inventoryApi.uri property to set to the IP address of the server.
• Make sure to configure the inventoryApi.sender and inventoryApi.passphrase properly. You can find valid passphrases in the testnet config file core/packages/core/bin/config/testnet/delegates.json. Use ARK Desktop Wallet to import the passphare and get the wallet's address.
• To register the client as a node of the ARK network, change the file core/packages/core/bin/config/testnet/peers.json and add server's ip to the list.

Install dependencies

cd ~/core
yarn setup

Run the application

cd ~/core/packages/core
yarn full:testnet

The output may be a bit verbose, but you should see the message ark-taco-shop available and listening on port 3000 in it.

To test it, access the frontend using the link http://0.0.0.0:3000. You should see the homepage.
