Fauna Serverless Framework plugin usage example

Serverless quick start Serverless Fauna plugin Fauna get started

Structure of this repository

• fql - Fauna Query Language (FQL) queries used in serverless.yml.
• functions - AWS Lambda functions for accessing your database.
• jsonSchemas - Used to specify the request shape for Amazon API Gateway.
• seed - A Lambda function to populate your database with demo data.

Setup

• Create an empty database in the Fauna dashboard.
• Create an Admin key for your new database and copy the generated secret.
• Copy .env.sample to .env and paste the generated secret as the FAUNA_SECRET value.
• Run npm install to install dependencies.
• Run serverless fauna deploy to create the Fauna collections, indexes, roles, and functions in your database.
• Run serverless invoke local --function seed to seed your database with demo data.

Deploy to Amazon Web Services (AWS)

serverless deploy

After you deploy, you have the following database schema populated with the demo data from the seed directory.

[
  {
    data: [
      Collection("customers"),
      Collection("orders"),
      Collection("products"),
      Collection("stores")
    ]
  },
  {
    data: [
      Index("products_by_customer"),
      Index("all_orders"),
      Index("all_customers"),
      Index("all_stores"),
      Index("all_products"),
      Index("products_by_store"),
      Index("products_by_price_high_to_low"),
      Index("products_by_price_low_to_high"),
      Index("customer_by_email"),
      Index("orders_by_customer")
    ]
  },
  {
    data: [Role("customer")]
  },
  {
    data: [Ref(Ref("functions"), "submit_order")]
  }
]

The Serverless Framework also creates an Amazon API Gateway REST API and Lambda functions and connects them together.
