Introduction

ForerunnerDB allows you to create, read, update and delete JSON objects called documents that are stored in collections. Collections are like tables in traditional databases such as MySQL. Collections of documents can be queried using the same query language as MongoDB so those familiar with MongoDB will find it easy to get started with ForerunnerDB.

You can find out more about ForerunnerDB and read the full manual and documentation on the official site at http://www.forerunnerdb.com.

Basic Usage

When you have ForerunnerDB loaded on your HTML page you can create a new database and store data in it immediately. To create a new database you use:

var fdb = new ForerunnerDB(),
    db = fdb.db('myDbName');

Collections are created automatically when requested so you can create or get a collection via:

var collection = db.collection('myCollectionName');

Storing documents (JSON objects) in Forerunner is very easy, simply insert the document like so:

collection.insert({ name: 'Jim', age: 15 });

Once you have documents in a collection you can query it like this:

var arrayOfJims = collection.find({ name: 'Jim' });

Updating a record is just as simple, pass the query to match the documents you wish to update, then the change you wish to make. To update all documents where the name === 'Jim' to age 20 simply write:

collection.update({ name: 'Jim' }, { age: 20 });

Finally you can remove documents as easily as inserting them:

collection.remove({ name: 'Jim' });
