This article is in continuation of my previous article wherein we built a minimalistic application to pull AWS DynamoDB data from a locally hosted Graphql server.

Now we will modify the code further to run the same code as AWS Lambda function deployed through Serverless.

STEP 4: Make a lambda function

Apollo Server provides binding for lambda function through apollo-server-lambda module.

Change server.js, and rather than running Apollo Server, export an apollo GraphQL lambda function which AWS lambda will invoke based on HTTP event.

const { ApolloServer, gql } = require(‘apollo-server-lambda’);

const handler = server.createHandler({
  cors: {
    origin: true,
    credentials: true,
  },
});
exports.graphqlHandler = handler;
