getting started

Give this a try

• yarn add subsystem subsystem.fastify fastify
• export const handle = (callContext: CallContext) => { callContext.output.body = 'hello world' } > routes/hello.ts
• yarn subsystem -e hello should see { headers: {}, body: 'hello world' }
• yarn subsystem -p subsystem.fastify, wait a little bit and visit http://localhost:3000/hello, you should see hello world as result
