Install

Before moving forward, you will need make sure you have a Twilio account setup and create an accountSid and token for a SMS phone number. TxtZ can be installed using two different methods using either a docker and docker-compose install or TxtZ can be installed manually. Before moving forward with the docker and docker-compose install method, please make sure you have docker installed before continuing as these instructions do not cover how to install and setup docker.

Install Using Docker Compose

The fastest and easiest way to get TxtZ up and running is to use docker and docker-compose. The docker-compose command will download, setup, and install the Nodejs app, MySQL, and the BitcoinZ Full node. This makes it easier to jump into TxtZ without having to worry about all of the dependencies.

To get started, checkout TxtZ from git and change to the project directory:

git clone https://github.com/bitcoinz-wallets/TxtZ.git
cd TxtZ

Next, copy the env-defaults template to the docker-compose environment file:

cp ./docker/env-defaults .env

The .env file is where the Twilio configuration will go for the docker-compose environment. Next, you will want to edit the .env file and add the required Twilio configuration:

vim .env

Finally, launch the TxtZ service with the following command:

docker-compose up

Other Docker Compose Commands

To launch TxtZ as a daemon and run in the background, you can use the following command:

docker-compose up -d

The docker-compose command should show you a log output, however, if it does not or you are running as a daemon you can use the following command to see the logs:

docker-compose logs -f -t

Manually Installing TxtZ

If not using docker and docker-compose, follow these instructions to Manually setup TxtZ

Configure TxtZ

Configure the project by editing config found in config/default.js. At the minimum you will need to update the config with your Twilio accountSid, token, and SMS number.

Install npm dependencies

Install the npm dependencies using the following command:

npm install

Setup MySQL

This project requires the txtz database to be created in MySQL. Create it by executing the following:

$ mysqladmin -u root -p create txtz

Create the hubs mysql user and give it permissions to the database from the mysql CLI:

mysql> CREATE USER 'txtz'@'%' IDENTIFIED BY 'btczftw!';
mysql> grant all on txtz.* to 'txtz'@'%';

Run the knex migrations

./node_modules/.bin/knex migrate:latest

Setup BitcoinZ Full Node

Build and setup a BitcoinZ node using the insight patched node repository: https://github.com/btcz/bitcoinz-insight-patched

Services

When Twilio receives a message, the Twilio service will send a notification to the TxtZ webhook. The Twilio webhook runs on the following service: http://localhost:3838/message

It will probably be necessary to proxy the Twilio webhook using a service like https://ngrok.com
