OnFire

OnFire is a library that makes it easier to develop and maintain Firebase apps that have complex data structures, whether they are browser-based or run on Node.js.

Already implemented:

• Schema-driven, live models. Where appropriate, property values are also models, automatically.
• Makes Promises, instead of actually calling you back. :laughing:

Coming soon:

• Atomic operations that involve multiple models simultaneously.
• Persistence! This is for loading data while offline, or for priming your app for a quick start.

Here are more details.

Examples

var Person = onfire.defineModel(
    {
        firstName: 'string',
        lastName: 'string',
        jobs: {
            $id: {
                title: 'string',
                company: 'string',
                startYear: 'number',
                endYear: 'number'
            }
        }
    });

// Access an object at a specific location:
var person = new Person(ref);
person.whenLoaded().
    then(function(person) {
        // Do something with the person.
    });

// A getter/setter is generated for each property specified in the schema.
console.log(person.firstName());

// The jobs property is automatically instantiated as a collection model.
console.log(person.jobs().count())

// Chainable setters:
person.firstName('Fred').lastName('Bloggs');

// After setting the values, we need to save the changes:
person.save().then(...); // a promise.

// or all together:
person.
    firstName('Fred').
    lastName('Bloggs').
    save().
    then(...);

// This will throw an exception, because of the mis-spelt property name.
// Schema-driven modules reduce the chances of unintentional errors in your code.
person.frtisName('John');

// Collections can be conveniently manipulated.
person.jobs().fetch('abc-123-def').
    then(function(job) {
        // job is a model. It is already loaded, i.e. no need to call .whenLoaded().
    });

// Add a new member to a collection.
person.jobs().create(
    {
        title: 'VP Sales',
        company: 'Claritude Software Ltd.',
        startYear: 2014
    }).
    then(function(job){
        // job is a model.
        // A key was automatically generated for it.
        // It is already loaded.
        console.log(job.key());
    });


// When a member's ID is predetermined, fetchOrCreate() will fetch it if it already exists, and
// create it if it doesn't. This is, of course, performed transactionally.
person.jobs().fetchOrCreate('zyx-321-cba',
    {
        title: 'Team Leader',
        company: 'ABC & Co. Ltd.',
        startYear: 2013,
        endYear: 2014
    }).
    then(function(job) {
        // job now exists in the database.
    });

How to use OnFire in your project

Browser based projects

• Load onfire.min.js into your project, after the line that references Firebase. For example:
  <script src="./bower_components/onfire/dist/onfire.min.js"></script>
• Optional: bower install --save isabo/onfire

Node.js based projects

• npm install --save onfire
• var onfire = require('onfire');

How to set up the development environment

This is not needed if you just want to use OnFire in your project.

Pre-requisites

• Java - used by Google Closure Compiler to optimise and minify Javascript.
• NPM - used to manage dependencies. This is usually installed together with Node.js.

Dependencies

• Install the dependencies locally: npm install
• Update the dependencies to the most recent compatible versions: npm update

How To Run the Test Suite

npm test

How to Build the Distributables

npm run build
