react-visible

A simple component to toggle visiblity and provide an optional fallback.

Install

npm install --save @codeparticle/react-visible

Usage

Note: Transitioning from v1 to v2 breaks the test snapshots.

Visible is easy to use. It has two required props, a condition when and a child component to render when that condition is true. It also supports the addition of a fallback prop if you'd like to show something else as a backup, such as a loader for a request that hasn't completed yet.

import React, { Component } from 'react'

import { Visible } from '@codeparticle/react-visible'

...

// Visible can be used to show different things in the same place depending
// on user-defined conditions.

const SignOutButton = ({ logOutHandler }) = <button onClick={logOutHandler}>Sign Out</button>
const SignInButton  = ({ logInHandler }) =  <button onClick={logInHandler}>Sign In</button>

const ToggleLoggedInButton = ({ userIsSignedIn }) => (
<Visible
  when={userIsSignedIn}
  fallback={<SignOutButton logOutHandler={logOut} />}
>
  <SignInButton logInHandler={logIn} />
</Visible>
);

// It can also be used to show a loader for a request that's still waiting.

<Visible when={dataLoaded} fallback={<Loader />}>
  <Content {...props} />
</Visible>

// However, if you try to use nested properties of data that may or may not be loaded,
// you will hit an error. You'll need to encapsulate it in a component first.

// Don't do this if you're waiting on data to load:

<Visible when={dataLoaded} fallback={<Loader />}>
  <Content props={data.payload.nested.maybeExists} />
</Visible>

// Do this, with proper checks and data fallbacks in the Content component itself:

import { Content } from 'components';

<Visible when={dataLoaded} fallback={<Loader />}>
  <Content {...props} />
</Visible>
