Gatsby plugin to turn Firebase into a Gatsby data source.

Gatsby Firebase Source

Quick and dirty firebase source for Gatsby. Allows you to query your firebase data right into your statically generated pages with Gatsby.

Usage

npm install gatsby-source-firebase

Note: For older versions of Gatsby (v1, v2) use: gatsby-source-firebase@1.0.0

1. First you need a Private Key from firebase for privileged environments, find out how to get it here: https://firebase.google.com/docs/admin/setup (or click the settings gear > Service accounts tab > Generate New Private Key button at the bottom)

2. Place that private key .json file somewhere in your gatsby project (the root is fine).

3. Configure gatsby-config.js

// the plugin options are:
{
  credential,
  databaseURL,
  types: [{
    type,
    path,
    query,
    map
  }]
}

// Here's an example:

module.exports = {
  // the rest of your config
  plugins: [
    {
      resolve: `gatsby-source-firebase`,
      options: {
        // point to the firebase private key downloaded
        credential: require("./firebase-key.json"),

        // your firebase database root url
        databaseURL: "https://<your-database>.firebaseio.com",

        // you can have multiple "types" that point to different paths
        types: [
          {
            // this type will become `allWorkshop` in graphql
            type: "Workshop",

            // the path to get the records from
            path: "v2/data/workshops",

            // probably don't want your entire database, use the query option
            // to limit however you'd like
            query: ref => ref.limitToLast(10)

            // This allows you to map your data to data that GraphQL likes:
            // 1. Turn your lists into actual arrays
            // 2. Fix keys that GraphQL hates. It doesn't allow number keys
            //    like "0", you'll get this error pretty often:
            //    Error: Names must match /^[_a-zA-Z][_a-zA-Z0-9]*$/ but "0" does not
            // 3. Remove stuff you don't need.
            //
            // Feel free to mutate, we sent you a copy anyway.
            map: node => {
              // fix keys graphql hates
              node.nineteenEightyFive = node['1985']
              delete node['1985']

              // convert a child list to an array:
              return node.sessions = Object.keys(node.sessions).map(key => {
                return { _key: key, session: node.sessions[key] }
              })

              // finally, return the node
              return node
            },
          },

          // if your data is really simple, this should be fine too
          {
            type: "CourseDescriptions",
            path: "text/courseDescriptions",
          }
        ]
      }
    }
  ]
}

Enjoy!
