Yes, you can retrieve the AWS AppSync GraphQL schema outside of the AWS Management Console. AWS AppSync supports the standard GraphQL introspection query, which allows you to retrieve the schema programmatically.
Here’s how you can do this:
1. Setup AWS CLI:
Ensure that you have the AWS Command Line Interface (CLI) installed and properly configured with the necessary access permissions.
2. Obtain the GraphQL Endpoint:
You need to obtain the GraphQL endpoint for your AWS AppSync API. You can get this from the AWS Management Console, or if you have the AppSync API ID, you can use the following AWS CLI command:
bashaws appsync get-graphql-api --api-id YOUR_API_ID
3. Use curl
or any HTTP client:
To send the introspection query, you'll need your AppSync API URL and an API key (or other forms of authorization, depending on how you've set up your AppSync API).
Here's an example using curl
:
bashcurl \
-XPOST \
-H "Content-Type:application/graphql" \
-H "x-api-key:YOUR_API_KEY" \
-d '{"query": "query IntrospectionQuery { __schema { queryType { name } mutationType { name } subscriptionType { name } types { ...FullType } directives { name description locations args { ...InputValue } } } } fragment FullType on __Type { kind name description fields(includeDeprecated: true) { name description args { ...InputValue } type { ...TypeRef } isDeprecated deprecationReason } inputFields { ...InputValue } interfaces { ...TypeRef } enumValues(includeDeprecated: true) { name description isDeprecated deprecationReason } possibleTypes { ...TypeRef } } fragment InputValue on __InputValue { name description type { ...TypeRef } defaultValue } fragment TypeRef on __Type { kind name ofType { kind name ofType { kind name ofType { kind name } } } }", "variables": {}}' \
YOUR_GRAPHQL_ENDPOINT_URL
Replace YOUR_API_KEY
with your actual API key and YOUR_GRAPHQL_ENDPOINT_URL
with your actual endpoint URL.
This will return a JSON representation of your GraphQL schema.
Note:
Always remember to protect your API keys and not expose them in client-side code or public repositories. The above is just a demonstration and in production scenarios, you'd also want to think about more secure methods of access such as using AWS Cognito or IAM-based authentication.
