React Helmet

This reusable React component will manage all of your changes to the document head.

Helmet takes plain HTML tags and outputs plain HTML tags. It's dead simple, and React beginner friendly.

6.0.0 Breaking Changes

Example

1import React from "react";
2import {Helmet} from "react-helmet";
3
4class Application extends React.Component {
5  render () {
6    return (
7        <div className="application">
8            <Helmet>
9                <meta charSet="utf-8" />
10                <title>My Title</title>
11                <link rel="canonical" href="http://mysite.com/example" />
12            </Helmet>
13            ...
14        </div>
15    );
16  }
17};

Nested or latter components will override duplicate changes:

1<Parent>
2    <Helmet>
3        <title>My Title</title>
4        <meta name="description" content="Helmet application" />
5    </Helmet>
6
7    <Child>
8        <Helmet>
9            <title>Nested Title</title>
10            <meta name="description" content="Nested component" />
11        </Helmet>
12    </Child>
13</Parent>

outputs:

1<head>
2    <title>Nested Title</title>
3    <meta name="description" content="Nested component">
4</head>

See below for a full reference guide.

Features

Supports all valid head tags: title, base, meta, link, script, noscript, and style tags.
Supports attributes for body, html and title tags.
Supports server-side rendering.
Nested components override duplicate head changes.
Duplicate head changes are preserved when specified in the same component (support for tags like "apple-touch-icon").
Callback for tracking DOM changes.

Compatibility

Helmet 5 is fully backward-compatible with previous Helmet releases, so you can upgrade at any time without fear of breaking changes. We encourage you to update your code to our more semantic API, but please feel free to do so at your own pace.

Installation

Yarn:

1yarn add react-helmet

npm:

1npm install --save react-helmet

Server Usage

To use on the server, call Helmet.renderStatic() after ReactDOMServer.renderToString or ReactDOMServer.renderToStaticMarkup to get the head data for use in your prerender.

Because this component keeps track of mounted instances, you have to make sure to call renderStatic on server, or you'll get a memory leak.

1ReactDOMServer.renderToString(<Handler />);
2const helmet = Helmet.renderStatic();

This helmet instance contains the following properties:

base
bodyAttributes
htmlAttributes
link
meta
noscript
script
style
title

Each property contains toComponent() and toString() methods. Use whichever is appropriate for your environment. For attributes, use the JSX spread operator on the object returned by toComponent(). E.g:

As string output

1const html = `
2    <!doctype html>
3    <html ${helmet.htmlAttributes.toString()}>
4        <head>
5            ${helmet.title.toString()}
6            ${helmet.meta.toString()}
7            ${helmet.link.toString()}
8        </head>
9        <body ${helmet.bodyAttributes.toString()}>
10            <div id="content">
11                // React stuff here
12            </div>
13        </body>
14    </html>
15`;

As React components

1function HTML () {
2    const htmlAttrs = helmet.htmlAttributes.toComponent();
3    const bodyAttrs = helmet.bodyAttributes.toComponent();
4
5    return (
6        <html {...htmlAttrs}>
7            <head>
8                {helmet.title.toComponent()}
9                {helmet.meta.toComponent()}
10                {helmet.link.toComponent()}
11            </head>
12            <body {...bodyAttrs}>
13                <div id="content">
14                    // React stuff here
15                </div>
16            </body>
17        </html>
18    );
19}

Note: Use the same instance

If you are using a prebuilt compilation of your app with webpack in the server be sure to include this in the webpack file so that the same instance of react-helmet is used.

externals: ["react-helmet"],

Or to import the react-helmet instance from the app on the server.
