util Plugin

util has a very simple set of states and functions, but useful utilities are to be added.

Installation

nextdapp add util

Global States

url

represents the current url with Node.js URL object if getURL is executed.

Global Functions

getURL()

gets the current page URL, parses it with Node.js URL object and sets it to url.

Regular Functions

xNil

xNil means isNotNil. Only null and undefined are false.

It's equivalent to complement(isNil) in Ramda.

import { xNil } from "nd/util"

xNil(null) // false
xNil(undefined) // false

Examples

import { useEffect } from "react"
import { bind } from "nd"
import { xNil } from "nd/util"

export default bind(
  ({ url, init }) => {
    const { getURL } = init() // initialize global function as usual
    useEffect(() => {
      getURL() // call the function
    }, [])
    return <div>{ xNil(url) ? url.hostname : "" }</div> // show hostname
  },
  [ "url", "getURL" ] // bind predefined state and function
)
