gatsby-plugin-netlify-identity

Gatsby plugin which adds a React Netlify Identity Widget Provider for you.

This is a very light wrapper just to help automate the boring parts, please see https://github.com/sw-yx/react-netlify-identity-widget for more info on how to use RNIW.

Install

npm install --save gatsby-plugin-netlify-identity
## you may also need RNIW's peer dependencies
npm install --save react-netlify-identity-widget @reach/dialog @reach/tabs @reach/visually-hidden

How to use

// In your gatsby-config.js
module.exports = {
  plugins: [
    // You can should only have one instance of this plugin
    {
      resolve: `gatsby-plugin-netlify-identity`,
      options: {
        url: `https://your-identity-instance-here.netlify.com/` // required!
      }
    }
  ]
}

Options

To use this, you must have a Netlify site instance with Netlify Identity enabled (Deploy this demo to get started with one click). Then take the URL of that Netlify site and pass it in as the url for this plugin’s options.

Usage

Once installed, you are free to use react-netlify-identity-widget’s handy useIdentityContext hook anywhere in your Gatsby app. If you also want the authentication modal, you can import it as well. A good place to put this is in a Layout component, but really you could also put it in a Navbar component, it really doesn’t matter since you’re inside the context anyway.

Some sample code for your convenience:

// src/components/Layout.js
import React from "react"
import IdentityModal, { useIdentityContext } from "react-netlify-identity-widget"
import "react-netlify-identity-widget/styles.css" // delete if you want to bring your own CSS

const Layout = ({ children }) => {
  const identity = useIdentityContext()
  const [dialog, setDialog] = React.useState(false)
  const name =
    (identity && identity.user && identity.user.user_metadata && identity.user.user_metadata.name) || "NoName"

  console.log(JSON.stringify(identity))
  const isLoggedIn = identity && identity.isLoggedIn
  return (
    <>
      <nav style={{ background: "green" }}>
        {" "}
        Login Status:
        <button className="btn" onClick={() => setDialog(true)}>
          {isLoggedIn ? `Hello ${name}, Log out here!` : "LOG IN"}
        </button>
      </nav>
      <main>{children}</main>
      <IdentityModal showDialog={dialog} onCloseDialog={() => setDialog(false)} />
    </>
  )
}

export default Layout
