React NoScript

Nest HTML tags under the tag in React

The HTML <noscript> tag lets you to display a custom message when a clients browser does not support JavaScript. However, when you nest HTML tags under the <noscript> tag in React, it creates the following error.

Uncaught Error: Invariant Violation

This component bypasses that error.

Installation

The easiest way to use react-noscript is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).

You can also use the standalone build by including dist/react-noscript.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install react-noscript --save

Usage

Import the component

var NoScript = require('react-noscript');

If you are using es6, import it the following way.

import NoScript from 'react-noscript';

Next implement the component wherever you want to notify your clients that their browser does not support JavaScript.

<NoScript>
    <div style={{padding: '20px', backgroudColor: 'orange', width: '100%'}}>
        <h1>Yikes!!!!</h1>
        <h5>It looks like this page does not have JavaScript enabled.</h5>
    </div>
</NoScript>

Notes

If you implement this component with a message outside of HTML tags, like below . . .

<NoScript>
    Yikes, your browser does not support JavaScript!
</NoScript>

. . . it creates the following error.

Invariant Violation:renderToStaticMarkup():

This component only works on Isomorphic or Universal React applications.

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link).
