example-apps

How to use:

1. Create your heroku app without an access-key
2. Initialize directory for Hasura GraphQL Engine

hasura init <app-name>

3. cd into and edit config.yaml to update the endpoint
4. Run pg_dump to dump the required schemas

pg_dump -h host -d database -U user --attribute-inserts -n schema1,schema2 > migrations/1_init.up.sql

5. Export metadata by running:

hasura metadata export

6. Commit all your changes and push to git.
7. Add accounts@hasura.io as collaborator (Important)

heroku access:add accounts@hasura.io --app <app-name>

Buildbot Workflow (this will happen automatically every 30mins):

1. Clone the examples-apps repo
2. Reset postgresql database by running:

heroku pg:reset --app <app-name> --confirm <app-name>

3. Restart the app so that graphql-engine is initialized

heroku restart --app <app-name>

4. Apply the migrations by running:

hasura migrate apply

5. Apply the metadata by running:

hasura metadata apply

Optional files:

• A README that describes your app
• A queries.graphql file that lists your sample GraphQL queries that GraphiQL will automatically be loaded with

# Insert author
mutation {
  insert_author(objects: [{name: "natwarlal"}] {
    returning {
      id
    }
  }
}

# Query author
query {
  author {
    id
    name
  }
}

What is the point?

• A script will refresh all the databases every 30mins for all the example apps (it will run the migrations in the migrations directory)
• This way you can safely share the Hasura GraphQL engine link with whoever and put it wherever you want, like in your blogpost or on the Hasura website or in a forum or on quora
