Evolutility.js

Evolutility provides a set of generic Backbone Views to browse, edit, filter, export and chart Backbone models and collections of different structures. With it you can make web applications by configuring views with metadata instead of hand-coding templates, Javascript and CSS.

This version of Evolutility uses your browser localstorage to store its data. The server-side for REST is a work in progress at Evolutility-server using Node.js and Postgres.

Demo apps

Sample Single Page Apps made with Evolutility: To Do list, AddressBook, Wine Cellar, Graphic Novels.

Views

Evolutility's views have a Backbone model (to define the data) and also a UI-model (to define the UI to display the data and interact with it).

All views for a Backbone model and collection share a single UI-Model which defines of all UI elements across views in a simple declarative way.

Evolutility provides 3 types of view

• Views for a model: Browse, Edit, Mini (quick edit), JSON.
• Views for a collection: List, Cards, Bubbles, Charts.
• Views for actions on a model or collection: Filter, Export, Import.

A large part of the API (methods, options and events) is common to all views. Some views have additional API.

Views for One model

Browse

Shows all fields for viewing (read only). Fields are grouped in panels and tabs.

var vw = new Evol.ViewOne.Browse({
            el: myElement,
            uiModel: myUIModel,
            model: myModel
        });

Edit

This view shows all fields for edition to create or update models. It automatically performs validation based on the UI-model and supports the Master-Details pattern (nested collections). Fields are grouped in panels and tabs.

var vw = new Evol.ViewOne.Edit({
            el: myElement,
            uiModel: myUIModel,
            model: myModel
        });

Mini

Used for quick edits. Only shows important fields (required or showing as a column in grids). Fields are grouped in a single panel.

var vw = new Evol.ViewOne.Mini({
            el: myElement,
            uiModel: myUIModel,
            model: myModel
        });

JSON

JSON representation of the data.

var vw = new Evol.ViewOne.JSON({
            el: myElement,
            uiModel: myUIModel,
            model: myModel
        });

Views for a collection of Many models

List

Gives a tabular view of a collection with paging.

var vw = new Evol.ViewMany.List({
            el: myElement,
            uiModel: myUIModel,
            collection: myCollection
        });

Cards

Shows records side by side as cards.

var vw = new Evol.ViewMany.Cards({
            el: myElement,
            uiModel: myUIModel,
            collection: myCollection
        });

Bubbles

The "Bubbles" view displays the data as bubbles with controls to group them and set their color and size (this view uses D3.js). A tooltip with the Card view of the item show on mouse over.

var vw = new Evol.ViewMany.Bubbles({
            el: myElement,
            uiModel: myUIModel,
            collection: myCollection
        });

Charts

Draws charts about the collection.

var vw = new Evol.ViewMany.Charts({
            el: myElement,
            uiModel: myUIModel,
            collection: myCollection
        });

Views for Actions

Backbone Views for actions on a collection or a model.

Filter

View used to build a structured query to filter a collection.

var vw = new Evol.ViewAction.Filter({
            el: myElement,
            uiModel: myUIModel
        });

Export

View to define export options and preview the collection export in different data formats (CSV, TAB, HTML, XML, SQL and JSON).

var vw = new Evol.ViewAction.Export({
            el: myElement,
            uiModel: myUIModel,
            collection: myCollection
        });

Import

View to import data from a CSVor JSON file. It is a work in progress.

var vw = new Evol.ViewAction.Import({
            el: myElement,
            uiModel: myUIModel,
            collection: myCollection
        });

Live demo of these views.

UI-model

Views are not defined in templates but configured with a UI-model using a vocabulary with words like "field", "panel" and "tab" rather than "INPUT" and "DIV" to describe UI elements.

Here is the UI-model used to configure all views for the "Graphic Novels" app demo:
