Serverless Plugin SNS

This plugin easily subscribes your lambda functions to SNS notifications. If the required SNS-Topics don't exist, they will be created automatically during the deployment.

Note: This plugin supports Serverless 0.5.* (please see previous versions for older sls versions)

• the plugin uses a hook that is called after each deployment of a function
• you only have to deploy your function as usual sls function deploy
• add the following attribute to the s-function.json in your functions folder

  ...
  "sns": {
    "topic": "your-dev-sns-topic"
  },
  ...

• the topic will be created automatically, if not yet done
• topicnames can use the following dynamic template-names:

${project}
${stage}
${functionName}

example:
  "sns": {
    "topic": "${project}-sns"
  },

Subscribe a lambda to multiple SNS Topics

• put an array of topics to the sns attribute

  ...
  "sns": [
    {"topic": "your-dev-sns-topic1"},
    {"topic": "your-dev-sns-topic2"}
  ]
  ...
