Application Configuration

Important: These docs are for the outdated Jets 5 versions and below. For the latest Jets docs: docs.rubyonjets.com

You can set application-wide configurations in the config/application.rb file. You can configure global things like project_name, autoload_paths, function timeout, memory size, etc. Example:

config/application.rb:

Jets.application.configure do
  config.project_name = "demo"

  # config.prewarm.rate = '30 minutes' # default is '30 minutes'
  # config.autoload_paths = []

  config.function.timeout = 30
  # config.function.role = "arn:aws:iam::#{ENV['AWS_ACCOUNT_ID']}:role/service-role/pre-created"
  # config.function.memory_size = 3008
  # config.function.cors = false
  config.function.environment = {
    global_app_key1: "global_app_value1",
    global_app_key2: "global_app_value2",
  }

  # More examples:
  # config.function.dead_letter_queue = { target_arn: "arn" }
  # config.function.vpc_config = {
  #   security_group_ids: [ "sg-1", "sg-2" ],
  #   subnet_ids: [ "subnet-1", "subnet-2" ]
  # }
  # The config.function settings to the CloudFormation Lambda Function properties.
  # http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-lambda-function.html
  # Underscored format can be used for keys to make it look more ruby-ish.

  # config.api.authorization_type = "AWS_IAM" # default is 'NONE' https://amzn.to/2qZ7zLh
  # config.api.binary_media_types = ['multipart/form-data'] # default is ['multipart/form-data'] # Changing this will update the API Gateway DNS
  # config.api.endpoint_type = 'PRIVATE' # Default is 'EDGE' https://amzn.to/2r0Iu2L, you need to set an endpoint_policy if this is 'PRIVATE'
  # config.api.endpoint_policy = {} # Default is nil https://amzn.to/2r0Iu2L
  # config.api.vpc_endpoint_ids = [] # Default is nil https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-private-apis.html
end

Environment Specific Configs

You can set specific configs for different JETS_ENV in the config/environments folder. Examples:

config/environments/development.rb:

Jets.application.configure do
  config.function.memory_size = 1536
end

config/environments/production.rb:

Jets.application.configure do
  config.function.memory_size = 2048
end
