Build a blog powered by GitHub issues

This repo powers the OneGraph Product Updates blog at

All of the posts on the changelog are stored as issues on the OneGraph changelog repo.

When you visit the page at, a GraphQL query fetches the issues from GitHub via OneGraph's persisted queries and renders them as blog posts.

The persisted queries are stored with authentication credentials for GitHub that allows them to make authenticated requests. Persisting the queries locks them down so that they can't be made to send arbitrary requests to GitHub.

If you'd like to learn more about persisted queries, email or hop in our Spectrum chat.


Use an existing OneGraph app or sign up sign up at OneGraph to create a new app.

Copy /.env.example to /.env and update RAZZLE_ONEGRAPH_APP_ID with your app's id. This would also be a good time to replace RAZZLE_GITHUB_REPO_OWNER and RAZZLE_GITHUB_REPO_NAME in the /.env file with the repo name and owner for the repo you'd like to back your blog. You should also set RAZZLE_TITLE and RAZZLE_DESCRIPTION.

To create the token that's stored with the persisted query, you'll need to get a OneGraph token with GitHub credentials. Go the "Server-side Auth" tab in the OneGraph dashboard for your app, click the "Create Token" button, and add GitHub to the services. Set the token as OG_GITHUB_TOKEN in .env

You'll also need to get an API token for OneGraph itself to store persisted queries. Go to the "Persisted queries" tab on the OneGraph dashboard, scroll down, and click "Create token". This will create a scoped token for your app that can create persisted queries on your behalf. Set the token as OG_DASHBOARD_ACCESS_TOKEN in .env.

Remove the generated files (they're tied to the OneGraph app they were generated with)

yarn relay:clean
# which runs rm -r src/__generated__

(Note: any time you change the variables in .env, it's a good idea to stop the relay compiler, remove the files in src/__generated__, and restart the compiler)

Install dependencies

yarn install

Run the Relay compiler

This project uses Relay as its GraphQL client because of its high-quality compiler and great support for persisted queries.

In another terminal window, start the relay compiler

yarn relay --watch

You may need to install watchman, a file watching service. On mac, do brew install watchman. On Windows or Linux, follow the instructions at

Start the server

Now that we've generated the relay files, we can start the server.

yarn start

The project will load at http://localhost:3000.


The project comes with setups for deploying to Google's Firebase, Zeit's Now, Netlify, and

For each of these, you'll have to add the site that you're deploying to on the CORS origins on the OneGraph dashboard.

Deploying with Firebase

The project can use Firebase Hosting for static files and a Firebase Function to do server-side rendering.

There are sample firebase configs at /firebase.json.example and /.firebaserc.example. Copy those to /firebase.json and /.firebaserc. You'll want to edit /.firebaserc to use your firebase project.

cp firebase.json.example firebase.json
cp .firebaserc.example .firebaserc

Then add firebase-tools as a dev dependency.

yarn add --dev firebase-tools

Finally, set engines.node to "10" in the package.json

-  }
+  },
+  "engines": {"node": "10"}

Now you can deploy to firebase.

yarn build
yarn deploy:firebase

If you see an error when you visit the site, make sure the site's origin is listed in the CORS origins for your app on the OneGraph dashboard.

Deploying with Zeit

The project can be deployed with Now v2. There is a sample config at /now.json.example. First, copy it to /now.json.

cp now.json.example now.json

Then add now as a dev dependency

yarn add --dev now

To deploy

yarn build
yarn deploy:now

If you see an error when you visit the site, make sure the site's origin is listed in the CORS origins for your app on the OneGraph dashboard.

To see it in action, visit

Deploying with Netlify

The project can be deployed with Netlify and Netlify functions. The config lives in /netlify.toml and the functions live in /netlify-functions.

To deploy

yarn deploy:netlify

If everything looks good at the preview site, deploy to production

yarn deploy:netlify --prod

If you see an error when you visit the site, make sure the site's origin is listed in the CORS origins for your app on the OneGraph dashboard.

Deploying with

The project can be deployed with Create a new app at, then update the /fly.toml file to use your app.

You'll need to have the flyctl installed on your machine. Install the cli with

curl | sh

Then run

yarn deploy:fly

That will build a Docker image and upload it to You do not have to have Docker running on your machine. If it is not running, will build the Docker file for you with their hosted builders.

Project setup


The client is an ordinary React app. The best to place to start is /src/App.js.

It uses Grommet as the UI library. Visit to view the documentation for Grommet.

It uses Relay as the GraphQL client. has a good introduction to Relay.

To refresh the GraphQL schema, run yarn fetch-schema. That will fetch the schema from OneGraph and add some client-only directives that we use when we persist the queries to OneGraph.

How persisting works

The persistFunction for the relay compiler is set to /scripts/persistQuery.js. Every time a GraphQL query in the project changes, the relay compiler will call that function with the new query.

That function will parse the query and pull out the @persistedQueryConfiguration directive to determine if any auth should be stored alongside the query. In the changelog, the queries for fetching posts use persisted auth, but the mutations for adding reactions require the user to log in with OneGraph and use their auth.

The @persistedQueryConfiguration directive is stripped from the query and it is uploaded to OneGraph via a GraphQL mutation. Then the id for the persisted query is returned from the function. Relay stores the id in its generated file and it's used the next time the query is sent to the server.


The server uses Razzle to allow us to render the content on the server. This helps with SEO and allows people to view the blog with Javascript turned off.

Most of the work for the server-side rendering happens in /src/server.js.

When a request comes in to the server, the server creates a mock Relay environment and prefetches the query for the route using fetchQuery from relay-runtime. This populates the record source that Relay uses to render.

React renders the app to a string, which is sent to the client.

On the client, React rehydates the app. To prevent Relay from showing a loading state, we inject the serialized record source in a global window.__RELAY_BOOTSTRAP_DATA__ variable. That data is stored in the environment before Relay makes its first query. The dataFrom prop (which will move to fetchConfig in the next Relay release) on the QueryRenderer is set to "STORE_THEN_NETWORK" so that it uses the data from the store instead of showing a loading state.
