appsync-client-node
Lightweight AWS AppSync client for Node.js (optimized for AWS Lambda Node.js runtime(s)):
- supports IAM and API Key authentications
- supports XRay tracing or OpenTelemetry Lambda layers auto-instrumentation
- allow to specify URL via environment variable (
GRAPHQL_API_ENDPOINT_ENV_NAME
) - properly handles timeouts, abort signal and retries connection-reset errors
- comes with lightweight
gql
tag (just stipes whitespace and comments) for prettier, GraphQL VSCode syntax highlighting, etc. - ESM and CommonJs modules
- TypeScript generics support for variables and results
- depends only on
@aws-sdk
v3 (that comes built-in on Node 18.x lambda runtime) andaws-xray-sdk-core
that results in very small bundle (when used with CDKNodejsFunction
) - MIT licensed
