38% of CISOs Fear They’re Not Moving Fast Enough on AI
CISOs are racing to adopt AI for cybersecurity, but hurdles in budgets and governance may leave some falling behind in the fight against cyber threats.
A slot is a place in a component where you can insert any unknown component. It's a well-known abstraction used by frameworks such as Vue.js and Svelte.
Slots arn't present in the React. With React you can achieve this goal using props or React.Context. In large projects this is not convenient, because it generates "props hell" or smears the logic.
Using React with Effector we can achieve slot goals without the problems described above.
npm install --save-dev @space307/publish-wizard
# or
yarn add @space307/publish-wizard --dev
Define constant with slots name and call createSlotFactory
.
import { createSlotFactory } from '@space307/effector-react-slots';
export const SLOTS = {
FOO: 'foo',
BAR: 'bar',
};
export const { api, createSlot } = createSlotFactory({ slots: SLOTS });
Create Slot component.
import React from 'react';
import { useStoreMap } from 'effector-react';
import { createSlot, SLOTS } from './slots';
const { $slot } = createSlot({ id: SLOTS.FOO });
export const FooSlot = () => {
const Component = useStoreMap({
store: $slot,
fn: ({ component }) => component,
keys: [],
});
return <Component />;
};
Insert Slot component to your UI.
import React from 'react';
import { FooSlot } from './fooSlot';
export const ComponentWithSlot = () => (
<>
<h1>Hello, Slots!</h1>
<FooSlot />
</>
);
Render something inside slot. For example, based on data from feature toogle of your app.
import { split } from 'effector';
import { $featureToggle } from './featureToggle';
import { api, SLOT } from './slots';
const MyAwesomeFeature = () => <p>Look at my horse!</p>;
const VeryAwesomeFeature = () => <p>My horse is amaizing!</p>;
split({
source: $featureToggle,
match: {
awesome: (data) => msg.type === 'awesome',
veryAwesome: (data) => msg.type === 'veryAwesome',
},
cases: {
awesome: api.set.prepend(() => ({ id: SLOT.FOO, Component: MyAwesomeFeature })),
veryAwesome: api.set.prepend(() => ({ id: SLOT.FOO, Component: VeryAwesomeFeature })),
},
});
Best practices for writing well-typed code.
Props of component passed to slot can be defined as generic
const slot = createSlot<{ readonly text: string }>({ id: 'heading' });
Function that returns a function for creating slots and an API for working with slots.
Function, takes the slot name. Returns the table containing the slot
