Session value example

[stanonyime]

In the express-graphql repo, there is an example in the Readme demonstrating session usage. How will that look like with koa-graphql? Basically, I want to access session variables and use it in my schema

[santialbo]

this library needs to expose the koa context on the options function, not just the original node request.

[chentsulin]

It's undocumented, but this lib already expose the koa context on the options function now. https://github.com/chentsulin/koa-graphql/blob/master/src/index.js#L188

Example added. See https://github.com/chentsulin/koa-graphql/pull/22/files

Have I understood correctly that this:

app.use(mount('/api', graphqlHTTP((request, context) => ({
    schema: Schema,
    context: { foo: 'bar' },
}))));

...should make argument 3 on my schema's resolve equal { foo: 'bar' }? I currently get a schema object there instead, what am I missing? (Some fundamental fact about the graphql resolve method's "context" I assume)

{
  fieldName: 'viewer',
    fieldASTs: [ ... ],
    returnType: ....,
    parentType: ....,
    schema: ...,
    ...etc...
}

Thanks!

context only be supported after v0.5.0. You may use the old version of koa-graphql (< 0.5) and graphql (< 0.5). Here is the resolve's 3rd argument example before 0.5.0:

new GraphQLObjectType({
  name: 'MyType',
  fields: {
    myField: {
      type: GraphQLString,
      resolve(parentValue, _, { rootValue }) {
        //
      }
    }
  }
});

Ah, that explains it! I used the old version due to some conflicting peerDeps, but I'll sort em out and try the newer version. Thanks.

..since I'm still deep in peerDep problems (I think it's because isomorphic-relay hasn't upgraded yet), did I understand you correctly that there is no sensible way of getting the context data in 0.4?

[chentsulin]

@prewk You can achieve your goal using rootValue in 0.4. Please checkout old README here: https://github.com/chentsulin/koa-graphql/tree/v0.4.13#advanced-options

@chentsulin can't get it working following your example here https://github.com/chentsulin/koa-graphql/pull/22/files

First of all, routeValue is undefined in the resolve's context argument. If I try to store in session it doesn't store in the next session middleware call :\

// inside mutation

  mutateAndGetPayload: async ({ email, password }, context) => {
    console.log(`session: ${context.session}`)
    console.log(`mutateAndGetPayload`)

    const user = await getUserWithCredentials(email, password)

    // set session token so that user is authenticated on next requests via a cookie
    if (user) {
      /* eslint-disable no-param-reassign */
      context.session.token = createToken(user)
      console.log(`context.session.token: ${context.session.token}`)
      /* eslint-enable no-param-reassign */
    }
    return { user }
  },

// inside session middleware

export default async function sessionMiddleware(ctx, next) {
  console.log(`sessionMiddleware`)
  console.log(`ctx.session.token: ${ctx.session.token}`) // <<<<< UNDEFINED :(
}
