Installation

npm install --save graphql-ttl-transformer

How to use

Setup custom transformer

Edit amplify/backend/api/<YOUR_API>/transform.conf.json and append "graphql-ttl-transformer" to the transformers field.

"transformers": [
    "graphql-ttl-transformer"
]

Use @ttl directive

Append @ttl to target fields.

type ExpiringChatMessage @model {
  id: ID!

}

It is important that the field you use the directive is of type AWSTimestamp (recommended) or Int, as the expiration timestamp must be in Unix time format.
