Via package manager

Effector doesn’t depend on NPM, you can use any package manager you want.
For example: yarn, pnpm.

npm install effector


npm install effector effector-react

Also, you can start from Stackblitz template with TypeScript, ViteJS, and React already set up.


npm install effector effector-vue


npm install effector effector-solid


Svelte works with effector out of the box, no additional packages needed.

Online playground

Examples in this documentation are running in our online playground, which allows someone to test and share ideas quickly, without install. Code sharing, TypeScript and React supported out of the box. Project repository.


Just import effector.mjs from any CDN.

import { createStore } from "";

Sample CDNS:


Use effector-logger for printing updates to console, displaying current store values with browser ui and connecting application to familiar redux devtools.

To use Babel plugin, you don’t need to install additional packages, plugin bundled to effector package.

npm install --development @effector/swc-plugin @swc/core



The library provides separate modules with compatibility up to IE11 and Chrome 47 (browser for Smart TV devices): effector/compat, effector-react/compat, and effector-vue/compat

Usage with manual import replacement:

- import {createStore} from 'effector'
+ import {createStore} from 'effector/compat'

Usage with babel-plugin-module-resolver in your .babelrc:

  "plugins": [
        "alias": {
          "^effector$": "effector/compat",
          "^effector-react$": "effector-react/compat"


Effector uses some APIs and objects that older browsers may not have, so you may need to install them yourself if you intend to support such browsers.

You may need to install the following polyfills:

  • Promise
  • Object.assign
  • Array.prototype.flat
