An experimental set of tools for cross-platform framework-less development (500 lines of core + libraries!). Framework-less approach assumes you are willing to assemble the final thing yourself, buying more control and flexibility at the cost of additional boilerplate.

Think CycleJS without drivers built on Kefir, Kefir.DB, and React. Unredux is compatible with React ecosystem (except ReactRouter and some other high-level stuff replaced with a stream-based code here).

WIP. Highly unstable. Name is a temporary dummy thing.

Most frameworks allow you to override important stuff with options. Yet this approach is naturally limited as option objects simply ain't expressive enough to compete with a real code. As soon as your app's assumptions are different from that of a framework (a reasonable guess), you start tweaking stuff here and there, adding more and more ugly hacks in the process. In our experience, the best solution is often a framework removal.

If you don't like the imperative, object-oriented approach VueJS and MobX promote. If you are not satisfied with the bundle size, complexity and vendor locks of Angular and GraphQL. If you are sick of Redux ecosystem and willing to concentrate on the business logic – here's a solution.

Unlike those titles, you can read the whole code of Unredux in one sitting.


  • CycleJS-like architecture with sources and sinks but without drivers.
  • Reactive dataflow with proactive insertions.
  • Reactive state management (think Redux with functions instead of actions).
  • Full-scale examples: realistic routing, SSR, etc.
  • Declarative data fetching and auto-persistence (in progress).

Component model is as simple as possible (components are called apps here to differentiate them from React components):

function anyApp(sources, props) {
  sources      // {state$: streamOfStates, DOM: streamOfLocalDOMEvents, ...}
  ...          // -- your code --
  return sinks // {Component: reactComponent, action$: streamOfActions, ...}

where sources and sinks are records of streams (Object <KefirStream> speaking TypeScript), where keys are predefined and correspond to event or effect types (a complex sentece but it describes everything about the component model – try to do that for another framework).

Component "composition" is just a function and stream composition, nothing fancy. And as it's not a framework you can mix and swap stuff without a problem. For example, we use complex stateful React components like DnD and some unique jQuery plugins together with this architecture in production.


Also suggested:


1. Counter

A basic example.

2. Counters

Component isolation and reuse.

3.1 Pages

Pages and simple routing.

3.2 Router

Advanced routing (wip).

4. Todos

Classic "TodoMVC" app.

5. Todos-History

Todos with a flexible history management.

6. Shopping-Cart

Shopping Cart with interactions between "parent" and "child" apps.

7.1 CRUD

CRUD client-server apps showing async data fetching, posting, caching, and more.


Previous example extended with SSR.

8. DDL

Declarative Data Load, lightweight alternative to GraphQL+Relay / Falcor.

Notable differences:

  1. Unlike both (GraphQL / Falcor) it's REST API based (avoiding vendor lock-in on Backend).
  2. It's more reactive and declarative where it makes sense with clear fallback paths.
  3. Unlike GraphQL it relies on plain data to describe queries, instead of extra DSL layer.
  4. Less magic, more boilerplate. Model dependencies are described, not auto-injected.
  5. Much smaller code base and bundle size.
  6. Validations and Querying are decoupled. Use TsIO, PropTypes, Tcomb or any other dynamic typing to describe and validate your models. Avoiding vendor lock-in again.


Examples are expected to work in Browser and NodeJS environments. The latter will require babel-node (because of ES6 modules).

$ npm install babel-cli -g
$ npm install http-server -g


  1. Fork and download the repo.
  2. $ npm install in the root to pull common dependencies.
  3. $ cd <example_folder>.
  4. $ npm install to pull local example dependencies and symlink vendor libraries (see below).
  5. $ npm start (check package.json scripts).


  1. Create some.js file in the project root.
  2. Run the file with $ babel-node some.js.
  3. Required babel plugins and presets will be applied automatically.


  • Functional Programming (basics)
  • Lensing (basics)
  • React (basics)
  • Kefir (basics)



We use ASCII marble diagrams:

observable: ---v1---v2---> (time)

where v1 may denote a string "v1" or something else, which should be clear from a context.
