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, and...... File uploads support) GraphQL APIs in Node.js 🚀

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!

Hi guys, congratulations on v2!

taking this code as an reference:
readTextFile: async (_, { file }: { file: File }) => {
try{
const textContent = file.text()
console.log(textContent)
return textContent
}
catch(e){
throw(new GraphQLYogaError(e))
}
},

Could you please send me an example of how to read a stream/blog other than text (an image, for example).
