Fastify

Supported versions: v4 and v5

First, you need to ensure you have the libs installed, so run this code:

npm i --save fastify

Then, you need you just need to use the FastifyFramework when you create your adapter, like:

index.ts

import { ServerlessAdapter } from '@h4ad/serverless-adapter';
import { FastifyFramework } from '@h4ad/serverless-adapter/frameworks/fastify';

const Fastify = require('fastify');

const app = Fastify({ logger: true });
export const handler = ServerlessAdapter.new(app)
  .setFramework(new FastifyFramework())
  // continue to set the other options here.
  //.setHandler(new DefaultHandler())
  //.setResolver(new PromiseResolver())
  //.addAdapter(new AlbAdapter())
  //.addAdapter(new SQSAdapter())
  //.addAdapter(new SNSAdapter())
  // after put all methods necessary, just call the build method.
  .build();
