WARNING: This npm package is for the CanJS client-side MV* libraries. It was formerly the node-can project which has been moved to socketcan. A HUGE thanks to Sebastian Haas for letting us use the can name!

NOTE: The canjs NPM package name is deprecated. Use can instead.

CanJS is a collection of the following client-side JavaScript architectural libraries:

The best, most hardened and generally useful libraries in CanJS.

• Custom elements — can-component
• Observable…
  • Values — can-compute
  • Custom types — can-define
  • Lists — can-define/list/list
  • Objects — can-define/map/map
• Data connection and service modeling — can-connect and can-set
• Routing — can-route and can-route-pushstate
• Live binding templates — can-stache, can-stache/helpers/route and can-stache-bindings

Utility libraries that power the core and ecosystem collections.

• Unique identifiers — can-cid
• Inheritable constructor functions — can-construct
• Declarative event bindings — can-control
• Event handling utilities — can-event, can-event/async/async, can-event/batch/batch, can-event/lifecycle/lifecycle
• An environment agnostic container for global variables - can-globals
• Namespace where can packages are registered — can-namespace
• Observable hooks needed by every other observable — can-observation
• Reflection for gets/sets, events, and type inference across object types - can-reflect
• Reflection to treat Promises as objects with value and state - can-reflect-promise
• Simple observable — can-simple-map
• A Symbol polyfill - can-symbol
• A stateful container for CanJS type information — can-types
• Common DOM and JS utilities — can-util
• View helpers
  • Register custom elements or attributes in templates — can-view-callbacks
  • Keeps part of the DOM up to date with a compute — can-view-live
  • Read a view model from a custom element — can-view-model
  • Maintains — can-view-nodelist
  • Parses HTML and magic tags — can-view-parser
  • Lookup scope within a stache template — can-view-scope
  • A fast-path compile target — can-view-target

Useful libraries that extend or add important features to the core collection.

• Integrate can-connect with a FeathersJS Client (can-connect-feathers) or a SignalR Hub (can-connect-signalr)
• Call base functions from inside inheriting functions — can-construct-super
• Define property values using streams — can-define-stream
• Add validation methods and observables to a can-define/map/map using validate.js — can-define-validate-validatejs
• Simulate ajax requests (can-fixture) and socket.io services (can-fixture-socket)
• Cross-bind can events and jquery events — can-jquery
• Provides a set of converters useful for two-way binding with form elements — can-stache-converters
• Convert observable values into streams — can-stream and can-stream-kefir
• Shared utilities and type definitions to process validation errors — can-validate and can-validate-validatejs
• A virtual DOM that is able to run CanJS's templates — can-vdom
• Automatically render templates found in the document — can-view-autorender
• Import dependencies in CanJS views — can-view-import
• A context for tracking asynchronous activity in JavaScript applications — can-zone and a compatible memory-based storage — can-zone-storage
• A StealJS extension that allows stache templates as dependencies — steal-stache

Former libraries that we still accept patches for, but are not under active development.

• can-ejs
• can-list
• can-map
• can-map-backup
• can-map-define
• can-validate-legacy
• can-view-href
