Steps for configuring type definitions for an Apollo error response

Apollo's documentation explains that an error response can take the following form:

{
  "data": {
    "getInt": 12,
    "getString": null
  },
  "errors": [
    {
      "message": "Failed to get string!",
      // ...additional fields...
    }
  ]
}

How do I go about importing the type(script) definition for this response?

If we were to define the type, it might look like this:

type ApolloError = {
  data?: {
    getInt?: number,
    getString?: string | null
  },
  errors: { message: string, ... }[]
}

I'm thinking the import statement would be something along the lines of:

import type { Error } from 'some-apollo'

Alternatively, could a development package like '@types/apollo` handle this globally?

Answer №1

Is the definition already available on the client side?

There is a pre-existing definition for ApolloError in the Apollo Client.

import { ApolloError } from '@apollo/client/errors';

Check out the definition here
