pspublisher is a package for automatic, asynchronous CRUD operations on a Mongo database.

Installation

You can clone this repo with git clone https://github.com/vlmlee/pspublisher.git and then run npm install from inside the cloned directory to install the dependencies.

or you can install this package via npm:

npm install pspublisher

Motivation

This module was created for personal use on a blog. I thought it was unneccessary to have to write forms for your own website when we had all these powerful tools that could handle those file operations for us. A web application is "just a wrapper around a database" afterall.

So why not automate the process? And so we did.

Usage

pspublisher is built on top of chokidar and mongoose. Both are mature and robust modules that made this project possible. Both are built with asynchronicity in mind.

To use it, require it like:

const publisher = require('pspublisher').pspublisher;

and then define a path or directory that you want to watch. We also tell it what database to send our documents.

publisher('/path/to/directory');
publisher.connect('mongodb://localhost/myapp');

// or chained:

publisher('/path/to/directory').connect('mongodb://localhost/myapp');

After doing so, we can define a model to structure our documents. With this module, we want to create a model by using an array with three fields: name, schema, and collection. You can define the schema to be anything you like, as long as your documents match that schema. pspublisher currently has no support for subdocuments.

// Example
publisher.models([{
	name: 'Posts',
	schema: {
		name: String,
		body: String,
		url: String
	},
	collection: 'name-of-collection' // comments, for instance
}]);

Then you run the script with:

publisher.start();

Then, just set up your mongo database, move your files into that directory, and voila! It shows up in your database.

Recommendations

For the time being, only json files are supported. Make sure your schemas that have important requirements uses required. Also, as of right now, you can only use one schema for one instance of pspublisher.

To have the script automatically exit when an exception is thrown, you will want to change exitOnError on the logger to true:

publisher.logger({exitOnError: true});

Protect trackedFiles.json

Don't modify this file.

Further Work

A lot of further work needs to be done. Validating schemas, more support for multiple schemas and other files are in consideration. Some slight optimizations could also be done.
