gatsby-source-gravatar

Gatsby plugin to source Gravatar URLs from emails.

Install

yarn add gatsby-source-gravatar

# npm install --save gatsby-source-gravatar

How to Configure

In gatsby-config.js:

module.exports = {
  plugins: [
    {
      resolve: `gatsby-source-gravatar`,
      options: {
        // Required.
        // A list of emails to create URLs for.
        emails: [
          // Could be just a strings,
          `[email protected]`,
          // Or an object, to pass an optional gravatar `query` parameter per email (see below).
          { email: `[email protected]`, query: `?size=128` },
        ],

        // Optional.
        // No query string is passed to gravatar by default.
        // But you can add your gravatar query parameters here.
        // See https://en.gravatar.com/site/implement/images/
        // If this is set, it will be the default for `emails` (see above) with no `query` options.
        query: `?size=64&m=dp`,
      },
    },
  ],
}

This configuration adds the the generated URLs into Gatsby's GraphQL nodes. This means that, when integrated with libraries like gatsby-plugin-remote-images, it can be possible to get static Gravatar images that can be processed by gatsby-image.

How to Query

To get the Gravatar URL for one of the configured emails:

{
  gravatar(email: { eq: "[email protected]" }) {
    url
  }
}

To get all Gravatar URLs:

{
  allGravatar {
    edges {
      node {
        url

        # also, available are:
        email
        hash
        query
      }
    }
  }
}

Dynamic (On-Demand) Querying

Sometimes, we may not know which emails (and with what parameters) to include in gatsby-config.js ahead of time. So we can get the parsed URL using a method called toUrl:

import { useMemo } from 'react'
import { toUrl } from 'gatsby-source-gravatar'

function Profile({ email }) {
  const url = useMemo(() => toUrl(email, 'size=128'), [email])

  return <img src={url} alt={`${email}'s gravatar`} />
}

Exports

• toUrl: receives an email (and an optional query) parameter and responds with an a Gravatar URL.
• parseNode: receives an email (and an optional query) parameter and responds with a Node that can be passed to Gatsby's createNode method (this also includes this plugin's generated node data).
• parseData: receives an email (and an optional query) parameter and responds with an object containing the url, email, hash and query.
• digest: receives a string parameter and responds with its MD5 hash string.
