Created on 30 Nov 2017 · 4Comments · Source: gatsbyjs/gatsby

Hi guys! Sometimes i need to add some js scripts inside <body> but i have totally no idea how i could do that! Adding it to head it's easy with Helmet, but what about body?

Thanks!

Take a look at the file, as mentioned in the doc link. Looks something like this:

import React from "react"

let stylesStr
if (process.env.NODE_ENV === `production`) {
  try {
    stylesStr = require(`!raw-loader!../public/styles.css`)
  } catch (e) {
    console.log(e)
  }
}

module.exports = class HTML extends React.Component {
  render() {
    let css
    if (process.env.NODE_ENV === `production`) {
      css = (
        <style
          id="gatsby-inlined-css"
          dangerouslySetInnerHTML={{ __html: stylesStr }}
        />
      )
    }
    return (
      <html {...this.props.htmlAttributes}>
        <head>
          <meta charSet="utf-8" />
          <meta httpEquiv="x-ua-compatible" content="ie=edge" />
          <meta
            name="viewport"
            content="width=device-width, initial-scale=1, shrink-to-fit=no"
          />
          {this.props.headComponents}
          {css}
        </head>
        <body {...this.props.bodyAttributes}>
          {this.props.preBodyComponents}
          <div
            key={`body`}
            id="___gatsby"
            dangerouslySetInnerHTML={{ __html: this.props.body }}
          />
          {this.props.postBodyComponents}
        </body>
      </html>
    )
  }
}

Insert script where you'd normally insert it in the html structure. I suspect right before the body closes is what you're looking for.

Have a look at the docs for customizing html.js. It should do what you're asking.

@markmichon thanks!
So do i have to just add this

;<div
  key={`body`}
  id="___gatsby"
  dangerouslySetInnerHTML={{ __html: this.props.body }}
/>

and replace _this.props.body_ with <script>myCode</script> ?
Or just add <script> inside body as i would normally do?
