Feature/apollo engine example

[fabien0102]

Hello,

Just update the apollo-engine example with the official apollo guide steps (https://www.apollographql.com/docs/engine/setup-node.html) and retrieve all the tracing data into apollo engine 🤘

Can you add a code comment on why the compression library is needed?

[fabien0102]

Of course 😉

// Once instrumented, the tracing package will increase the size of responses traveling between your
// GraphQL API and the Engine proxy, because the requests will be augmented with additional tracing data.
// Because of this, we recommend that you enable gzip compression in your GraphQL server,
// since the added volume from the tracing format compresses well.
// ref: https://www.apollographql.com/docs/engine/setup-node.html#enabling-compression
server.express.use(compression())

@schickling do you prefer something like this, or just the ref?

[schickling]

I'd say one line + the link.

// Enable gzip compression
// ref: https://www.apollographql.com/docs/engine/setup-node.html#enabling-compression
server.express.use(compression())

Good enough? ^^

Done ;)

@fabien0102 have you already upgraded to apollo engine v1.0? They are using a different API now and it'd be great if you could update this example. I'm a bit confused about when to call apolloEngine.listen() relative to yoga's server.start().

not yet, but I can have a look into this on Monday ;)
