@effector/contract

Usage

import { contract } from '@effector/contract';

Create a model in a model.ts file and export all effector units:

import { createEvent, createStore } from 'effector';

export const buttonClicked = createEvent();
export const $counter = createStore(0);

$counter.on(buttonClicked, (counter) => counter + 1);

Create a page component in a page.tsx:

import React from 'react';
import { Text, Button } from 'my-ui';

export const ExamplePage = () => (
  <div>
    <Text>Counter: 1</Text>
    <Button onClick={() => {
    }}>Increment</Button>
  </div>
);

Now create effector units to correctly connects with:

import React from 'react';
import { createEvent, createStore } from 'effector';
import { useStore, useEvent } from 'effector-react';
import { Text, Button } from 'my-ui';

export const buttonClicked = createEvent();
export const $counter = createStore(0);

export const ExamplePage = () => (
  <div>
    <CounterText />
    <Increment />
  </div>
);

const CounterText = () => {
  const counter = useStore($counter);
  return <Text>Counter: {counter}</Text>;
};

const Increment = () => {
  const handler = useEvent(buttonClicked);
  return <Button onClick={handler}>Increment</Button>;
};

Also, you can use @effector/reflect:

import React from 'react';
import { createEvent, createStore } from 'effector';
import { reflect } from '@effector/reflect';
import { Text, Button } from 'my-ui';

export const buttonClicked = createEvent();
export const $counter = createStore(0);

export const ExamplePage = () => (
  <div>
    <CounterText />
    <Increment />
  </div>
);

const CounterText = reflect({
  view: Text,
  bind: { children: $counter.map((counter) => `Counter: ${counter}`) },
});

const Increment = reflect({
  view: Button,
  bind: {
    onClick: buttonClicked.prepend(() => {
    })
  },
});

Now you can connect the model with the page, create index.ts file:

import { contract } from '@effector/contract';
import * as model from './model';
import * as page from './page';

export { ExamplePage } from './page';

contract({ page, model });
