+## React Postgraphile
+
+### Why did you build this thing?
+
+I wanted to learn about Graphql and JWT tokens in Postgres
+
+### What is it
+
+A React app communicating with a Postgresql database
+Using React-Apollo and Postgraphile's API generation.
+
+```

+                               .Github API
+                                \|     \|
+                                 +------+
+```
+
+### So what does the app do?
+Creating users and and authenticate with JWTs in Postgres.
+Add a Github auth token and manage your Pull Requests / Repos
+
+### What do you need?
+* [Postgresql](https://www.postgresql.org/download/)
+* [Postgraphile](https://www.graphile.org/postgraphile) `yarn global add postgraphile` or `npm install -g postgraphile`
+* react-postgraphile `git clone https://github.com/skvale/react-postgraphile`
+
+### Getting it to work
+```bash
+cd react-postgraphile
+```
+
+Start Postgres
+
+```bash
+# for MacOS
+brew services start postgres
+# or
+# postgres -D /usr/local/var/postgres
+```
+
+Create a database:
+
+```bash
+createdb react_postgraphile
+```
+Populate it
+
+```bash
+psql -f database/create.sql -d react_postgraphile
+```
+
+Start Postgraphile to create a Graphql layer over the created database
+
+```bash
+yarn run postgraphile
+```
+
+You can check your Graphql out at [localhost:5000/graphql](http://localhost:5000/graphql)
+
+Run the React app in a new terminal
+
+```bash
+yarn start
+```
+
+and open [localhost:1234](http://localhost:1234) to see:
+
+<img alt='User sign in' src='./images/image1.png' height=250 />
+
+Registering a user creates a user as well as a jwt token and stores the token as a cookie called `jwt_token`.  Apollo adds that token to the header requests
+
+```js
+const authLink = token =>
+  setContext((_, { headers }) => ({
+    headers: {
+      ...headers,
+      ...token ? {Authorization: `Bearer ${token}`} : {}
+    }
+  }))
+```
+
+and Postgraphile uses that to know which user you are.
+
+When the app runs the query
+
+```js
+export default graphql(gql`
+{
+  currentPerson {
+    fullName
+  }
+}
+`)(App)
+```
+Postgres gets the user identified by the jwt token on the request.  No API server, just a database function.
+
+```sql
+create function react_postgraphile.current_person() returns react_postgraphile.person as $$
+  select *
+  from react_postgraphile.person
+  where id = current_setting('jwt.claims.person_id')::integer
+$$ language sql stable;
+```
+
+ and passes it into the component.
+
+<img alt='User authenticated' src='./images/image2.png' />
