GraphQL on serverless: beautify legacy APIs

SPEAKERS: Matteo Joliveau & Nicola Racco

DATE Wednesday, October 23

LOCATION EMiT Feltrinelli - piazzale A. Cantore 10

Updating legacy APIs and services is expensive and often straight-out impossible, but modern applications require more flexible APIs and offline-first support. Using GraphQL and AWS Lambda we can build a modern API while maintaining the existing infrastructure and services.

ABSTRACT

Updating legacy APIs and services is cumbersome, expensive and often straight-out impossible. On the other hand, modern applications require more flexible APIs, real-time data streams and offline-first support. Using GraphQL to power new applications allows reusing the current infrastructure by proxying and composing requests to the legacy services without having to rewrite them while keeping cost at a minimum by deploying the new API layer as serverless functions on AWS Lambda. We’ll start by building a simple GraphQL API and then look at how to deploy it in the cloud at practically no cost

TRAINING OBJECTIVES

This workshop will teach you:

– how to properly design and build GraphQL APIs using NodeJS

– how to proxy existing services and restructure the data as interconnected graphs

– how to deploy a GraphQL endpoint as a serverless function using AWS Lambda
