Prerequisites

• Neo4j
• Node.js 8.0+
• Google Datastore emulator
• Command Line Tools
•  Mac OS X: Xcode (or OS X 10.9+: xcode-select --install)
•  Windows: Visual Studio OR Visaul Studio Code + Windows Subsystem for Linux - Ubuntu
•  Ubuntu /  Linux Mint: sudo apt-get install build-essential
•  Fedora: sudo dnf groupinstall "Development Tools"
•  OpenSUSE: sudo zypper install --type pattern devel_basis

Getting Started

The easiest way to get started is to clone the repository:

# Get the latest snapshot
git clone https://github.com/webwallet/api.git webwallet

# Change directory
cd webwallet

# Install NPM dependencies
npm install

# Then simply start your app
node index.js

Note: It is recommended to install Nodemon. It watches for any changes in your node.js app and automatically restarts the server. Once installed, instead of node app.js use nodemon app.js. It will save you a lot of time in the long run, because you won't need to manually restart the server each time you make a small change in code. To install, run sudo npm install -g nodemon.

Project Structure

The project is structure using the microapi library, this library add underneath the http paths to expose in a plug and play web service. Unlike express.js, you don't to explicitly add every path and file in an initializer file. For instance the path for a POST to http://localhost:3000/transaction

Name	Description
api/definitions/	Definitions used in the app.
api/middleware/	Middleware for microapi.
api/routes/	Http routes for the api.
api/schemas/	Joi schemas to validate the incoming bodies for every route.
.dockerignore	Folder and files ignored by docker usage.
.env.example	Your API keys, tokens, passwords and database URI.
.eslintrc	Rules for eslint linter.
.gitignore	Folder and files ignored by git.
.travis.yml	Configuration files for continue integration.
index.js	The main application file.
docker-compose.yml	Docker compose configuration file.
Dockerfile	Docker configuration file.
package.json	NPM dependencies.
package-lock.json	Contains exact versions of NPM dependencies in package.json.

Note: There is no preference how you name or structure your views. You could place all your templates in a top-level views directory without having a nested folder structure, if that makes things easier for you. Just don't forget to update extends ../layout and corresponding res.render() paths in controllers.
