Obviel core

  • Decouple views from each other and from the server: URL-agnostic views, Javascript agnostic server.
  • deep jQuery integration with the render function: $('#foo').render(obj)
  • Declarative composite views (subviews).
  • Declarative setup of event handlers.
  • Support for long and short-lived views.


  • Obviel works with RESTful data structures on the server: hyperlinked JSON.
  • Supports bootstrapping single-page applications from a single URL; all the rest of the information can be retrieved through hyperlinks.

Templates for HTML generation

  • Loops, conditionals and variables, deliberately kept sweet and simple.
  • Sub-view rendering: Obviel views can be rendered directly from a template, making it very easy to compose complex UIs using Obviel views.
  • Internationalization support: mark up parts of your template so they can be extracted as message ids and be translated when the template renders.
  • Extensible with custom formatters and functions that adjust elements by DOM manipulation.
  • Support for client or server-side HTML generation.
  • Support for static HTML inclusion.
  • Pluggable system for client-side template languages, so that other client-side template languages can be plugged in.


  • Supports i18n of both plain JavaScript and Obviel templates.
  • Documented, gettext-style i18n workflow.

Obviel Forms

  • Powerful form framework built on basic Obviel views and JSON.
  • Forms load and save JSON directly, no HTML form decoding or generation on server, just work with JSON.
  • Widgets for textline, text, integer, float, decimal, boolean (checkbox), choice (drop-down), display, date, autocomplete, and more.
  • Client-side validation: instant error messages if the user ends the wrong data.
  • Server-side validation support for complex validation requirements that involve multiple fields.
  • Easily extensible with new widgets.
  • Powerful composite and repeating fields to construct complex nested forms out of simple widgets: fields that represent sub-objects and arrays of objects.
  • Integration with gettext i18n framework for custom translation of error messages.


  • extensive unit test coverage
  • well-structured JavaScript code that eats its own dogfood: Obviel Forms built on Obviel core.
  • Obviel core is less than 8 kB of minified JavaScript code, Obviel forms library is 22 kB. gzipped you can include them both in less than 10 kB!
