Implement after hook or error handling?

[pyrossh]

Right now I generate and start a transaction in the context function and if the graphql request fails due to an error I would like inspect the result if it has any errors and based on that to rollback/commit the transaction. It would be nice if we could have a function similar to context but gets called after the graphql function to clean up connections/log stuff etc.

It seems apollo-server-express already exposes this in the options
If there could be some way we can pass the apollo server options directly to it using yoga for customizing the apollo server used underneath.

Also it seems if an error occurs in the context function. It crashes the server. Currently my context function is async and checks the token. It would be great if could try to catch an error happening here and return it as a graphql error.

On the implementation, I think you can better structure the Option type. Also a log level is better than a boolean.

• formatError?: Function
• formatParams?: Function
• formatResponse?: Function
• logFunction?: LogFunction
• debug?: boolean

[pyrossh]

I've removed the debug option. I've put these new params in the props will/should it be in the options or should it be in a new field called apollo which will expose all low level apollo server options.

export interface Props {
  typeDefs?: string
  resolvers?: IResolvers
  schema?: GraphQLSchema
  context?: Context | ContextCallback
  options?: Options
  formatError?: Function
  formatParams?: Function
  formatResponse?: Function
  logFunction?: LogFunction
}

Hey, @Urigo from The Guild here!

You might know us from projects such as graphql-code-generator, envelop or graphql-tools.

For a long time we thought that the Javascript ecosystem is still missing a lightweight cross-platform, but still highly customizable GraphQL Server.

In the past the awesome Prisma team took on that great challenge and now we are happy to announce that we are continuing them and just released GraphQL Yoga 2.0 - Build fast, extensible, and batteries-included (Subscriptions, Serverless, File uploads support) GraphQL APIs in Node.js 🚀

And regarding the issue here, Yoga uses the Envelop plugin system under the hood which has a very powerful hooks system and a whole ecosystem of plugins, including error handling plugins:

We have been working a long time on version 2.0 and have been using it in our clients projects for a few months now and shared a couple of alpha cycles here.
Thank you all for your feedback and suggestions, you made this release possible!

Please try Yoga out again, give us feedback and help us spread the word on the new release!
