ghostjs-benchmark

Node.js benchmark based upon Ghost.js

This benchmark is created from https://ghost.org/features/

Ghost is a modern, open source publishing platform built on Node.js with an Ember.js admin client, a JSON API, and a theme API powered by Handlebars.js. Its default database is MySQL, connected via Bookshelf as an ORM layer.

Version

This version of the benchmark is based on Ghost.js version v1.17 Compatible with LTS releases of node >=6.9 <7.* and >=4.5 <5.* (Node v4 argon LTS) and >=8.9 (Node v8 carbon LTS)

Consequently, since it's based on this version of Ghost.js, it is compatible with node.js LTS versions >=6.9 <7.* and >=4.5 <5.*

This version is hacked to support all versions of node.
require-dir package used by gscan node module had to be upgraded since some of the deprecated features are not supported in node 8 anymore
More info about Ghost.js is at Supported Node.js versions

Start up of Ghost.js benchamark

Currently start-up and initialization of the database is yet to be automated.
The benchmark's config.production.json defaults to using MySQL database.

1. create an account in the mysql database and copy the information to config.production.json for Ghost

2. Import the contents from the mysql dump file ghost-db.mysql into the ghost_db database.

CREATE DATABASE ghost_db;

Then log out of the MySQL shell and type the following on the command line:

mysql -u [username] -p ghost_db < ghost-db.mysql

With that, you have imported ghost_db benchmark database into your destination system's MySQL.

3. Install all the node modules onto your system cd ghostjs-repo

npm install 

4. switch to a compatible version of Node.js and start the server
   For a single instance NODE_ENV=production GHOST_NODE_VERSION_CHECK=false node index.js
