AppSync Javascript resolver implementation

This package provides an implementation for the @aws-appsync/utils package that is available on AWS.

Requesting functions to be implemented

We do not yet cover all functionality as provided by AWS AppSync. To request missing functions, or to see our function coverage, please see #19.

Development workflow

The test suite has automatic comparison with AWS. The testing workflow looks like:

• Add the test to __tests__/index.test.js passing the string text of the utility you wish to test, for example

test("string", async () => {
  await checkValid(`util.dynamodb.toDynamoDB("test")`);
});

• Run the test against AWS to capture the snapshot:

npm run test:aws

• Run the tests against the local package, using the snapshot for the ground truth

npm run test
