ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
Deku is a library for rendering interfaces using pure functions and virtual DOM.
Instead of using classes and local state, Deku just uses functions and pushes the responsibility of all state management and side-effects onto tools like Redux. It also aims to support only modern browsers to keep things simple.
It can be used in place of libraries like React and works well with Redux and other libraries in the React ecosystem.
Deku consists of 4 modules packaged together for convenience:
element
: Creating virtual elementsdiff
: Computing the difference between two virtual elementsdom
: DOM rendererstring
: HTML string renderernpm install --save deku
We support the latest two versions of each browser. This means we only support IE10+.
import {dom, element} from 'deku'
import {createStore} from 'redux'
import reducer from './reducer'
let {createRenderer} = dom
// Dispatch an action when the button is clicked
let log = dispatch => event => {
dispatch({
type: 'CLICKED'
})
}
// Define a state-less component
let MyButton = {
render: ({ props, children, dispatch }) => {
return <button onClick={log(dispatch)}>{children}</button>
}
}
// Create a Redux store to handle all UI actions and side-effects
let store = createStore(reducer)
// Create a renderer that can turn vnodes into real DOM elements
let render = createRenderer(document.body, store.dispatch)
// Update the page and add redux state to the context
render(
<MyButton>Hello World!</MyButton>,
store.getState()
)
