Jojo NPM | npm.io

jojo

the 10 second blog-engine for hackers (in javascript).

It was built for running as middleware inside an express app as well as a standalone application.

// articles/the-wonderful-wizard-of-oz.md
{
  "title": "The Wonderful Wizard of Oz",
  "author": "Lyman Frank Baum",
  "date": "1900/05/17"
}

Dorothy lived in the midst of the great Kansas prairies, with Uncle Henry,
who was a farmer, and Aunt Em, who was the farmer's wife.

// app.js
var jojo = require('jojo'),
    app = jojo();
app.listen(5000);
// Server is listening at http://localhost:5000/
// "The Wonderful Wizard of Oz" is being served at `/1900-05-16-the-wonderful-wizard-of-oz`

Getting started

Middleware

jojo is available via npm: npm install jojo

jojo is invoked with a configuration and can return a middleware or express app.

var app = jojo(); // express app
var app = jojo({render: false}); // vanilla middleware

By default, jojo reads articles that match articles/*.{txt,md} (txt and md files in articles directory) but this can be overridden via an option.

If you want more information on pattern options, see node-glob reference.

var app = jojo({articles: 'papers/*.md'}); // Read articles from `papers`

By default, all articles are interpretted via marked, a GitHub flavored markdown parser.

More configuration options can be found in the documentation.

Standalone

To run jojo as a standalone server, install jojo globally: npm install -g jojo.

jojo looks for a jojo.js/jojo.json to read in settings. These settings are passed to both a jojo middleware and express app.

jojo also accepts arguments for choosing a different config or port.

$ jojo --help
Usage: jojo [options]
Options:
  -c, --config [config]  Config file to use (jojo.js, jojo.json)
  -p, --port [port]      Port to run server on (5000)

port can also be specified in jojo.js/jojo.json

Documentation
