TypeScript compilation error with latest apollo packages

[bbugh]

It looks like Apollo changed some types in the latest versions, and vue-apollo is no longer compiling.

I'm on "vue-apollo": "^3.0.0-beta.28",

Here are the packages I upgraded to:

  "dependencies": {
    "apollo-cache-inmemory": "^1.5.1",
    "apollo-client": "^2.5.1",
    "apollo-link": "^1.2.11",
    "apollo-link-context": "^1.0.17",
    "apollo-link-error": "^1.1.10",
    "apollo-link-http": "^1.5.14",
    "apollo-link-ws": "^1.0.17",
    "apollo-utilities": "^1.2.1",
  },
  "devDependencies": {
    "@types/graphql": "^14.2.0",
  }

The ExecutionResult errors may be related to apollographql/apollo-link#910, but the VueApolloSubscriptionOptions<V, R> are in vue-apollo.

Same errors here:

@bbugh what did you do to bypass this?

[glen-84]

I'm seeing the same as @lucasrrt after updating apollo-boost.

Interface VueApolloMutationOptions has:

optimisticResponse?: ((this: ApolloVueThisType<V>) => any) | Object;

Interface MutationBaseOptions has:

optimisticResponse?: T | ((vars: TVariables) => T);

And they are not compatible.

I'm sure this is not the proper way to address this issue, but the following change in VueApolloMutationOptions (in types/options.d.ts) works around the error.

optimisticResponse?: ((this: ApolloVueThisType<V>) => any) | any;

Changing the type declaration from Object to any temporarily gets past this error for me:
From

optimisticResponse?: ((this: ApolloVueThisType<V>) => any) | Object;

To

  optimisticResponse?: ((this: ApolloVueThisType<V>) => any) | any

With that error quieted, how does one make use of vue.d.ts? I can't get VS Code to recognize things like $apollo, etc.

this.$apollo works for me :P Try removing the import VueApollo from 'vue-apollo'; statement and re-typing it back, autocompleting the module name. It worked for the same problem with a different module.

[nurkkala]

It turned out that I was using a VS Code workspace that contained the source tree in which I'm using vue-apollo. Somehow the tsconfig in the source tree wasn't properly being recognized by tsserver. When I reopened just the source tree (no workspace), it started working. So I have a workaround, but if anyone has insight into why VS Code behaves this way (or maybe how I misconfigured it!), I'd be glad to hear it.

This is actually a bad thing to do, but we can:

1. Open a issue requesting this change or
2. Make a fork of the this project, make this change, deploy it and use this version on your Vue project

[JohannesLamberts]

I got around the compilation error by creating a types.d.ts file in my project overriding the vue-apollo types:

import { MutationOptions } from 'apollo-client'
import { ApolloVueThisType } from 'vue-apollo/types/options'

declare module 'vue-apollo' {
  export interface VueApolloMutationOptions<V, R> extends MutationOptions<R> {
    optimisticResponse?: ((this: ApolloVueThisType<V>) => R) | R
  }
}

Another solution to work around broken builds is to install the linked PR #627 by changing the dependency in your package.json to:

{
  "dependencies": {
    "vue-apollo": "github:Akryum/vue-apollo#pull/627/head"
  }
}

@Akryum This issue should probably be closed now.

[Akryum]

Yes! 😸
