tyr

A CLI tool to scaffold Node.js microservice applications with DevOps capabilities. It takes an opinionated approach, meaning we've done the homework and start you off with what we think are the best tools for a small team creating a new open-source project. Upon running the CLI, it will ask you a series of questions and use the answers to do the following:

• generate a new Node.js project,
• add testing, web, and orm frameworks,
• setup Skadi, our data monitoring library,
• initialize and push the code to a new GitHub repository,
• establish a continuous integration environment,
• build a container for the code, and
• deploy the app container to a cloud service.

The goal is to save you time and headaches and get you started developing code faster.

Getting Started

Prerequisites

Before you can use Tyr, you need to make sure you've done the following:

1. Create a GitHub account. At this current stage of development, GitHub is the default version control platform for storing and managing your code.
2. Ensure that you linked your TravisCI account to your GitHub account.
3. Create a Heroku account. At this current stage of development, Heroku is the default web hosting service.
4. After creating a Heroku account, find your API key here. Make sure to copy it as you'll need it to sign in to Heroku.

Installation

npm install --global tyr-cli

Usage

tyr [OPTIONS]

Options:

• -V, --version output the version number
• --config <file> configure project from configuration file
• --logfile <file> the filepath that logs will be written to
• -h, --help output usage information

Using Tyr as a Library

Api	Description
async generateProject(configs)	The configs json object should have the same format as the .tyrfile. This method calls all the other API methods and does all the work to set up the project. It will not throw an error though, if an error occurs. The error will be written to the log. See other API methods for greater descriptions of functionality.
async generateBasicNodeProject(configs, filePath)	The configs json object should have the same format as the .tyrfile. The filePath is where the project will be created. This generates the most basic node files including /src index.html index.js package.json README /config It returns the configs object.
async setUpThirdPartyTools(configs)	The configs json object should have the same format as the .tyrfile. This function sets up the requested third-party applications for the new project.,This may take a few minutes if TravisCI is enabled while it waits for Travis to sync. If something goes wrong, an error will be thrown.
async generateStaticFiles(configs, filePath)	The configs json object should have the same format as the .tyrfile. The filePath is where the project will be created. Generates the static files necessary for third party applications. This method is dependent on changes to herokuAppName which will be added to the configs after setUpThirdPartyTools. If something goes wrong, an error will be thrown.
async commitToGithub(configs, filePath)	The configs json object should have the same format as the .tyrfile. The filePath is where the project will be created. This function initializes a local git repository, adds the project files, and then commits them to Github. If something goes wrong, an error will be thrown.
