Prerequisites

Install the Serverless Framework CLI.

Getting Started

git clone [email protected]:CryptoUnico/serverless.git
cd serverless
nvm use
npm install

Set your environment variables

You can find and update the function's configuration in serverless.yml:

service: serverless
provider:
  name: aws
  runtime: nodejs12.x
  region: ap-southeast-1
  timeout: 30
  environment:
    DEFAULT_GAS_PRICE: 60000000000
    MNEMONIC: ...

This example uses the following environment variables:

• DEFAULT_GAS_PRICE: Default gas price used when making write transactions.
• MNEMONIC: 12-word mnemonic used to derive an Ethereum address, make sure it's funded with Ether if you intend to write data to Ethereum!
• SLACK_HOOK_URL: The example sends messages to Slack using Incoming Webhooks. You can get this URL from your Slack dashboard. (Optional)

You can change your deployed function's environment variables on the fly from the AWS Lambda console.

Triggering the function locally

serverless invoke local --function exec

This will execute the smart contract function from your local machine. Great for debugging and testing.

Deploying to AWS

npm i -D serverless-dotenv-plugin
serverless deploy
