Typescript is throwing a fit because it doesn't like the type being used

Here is a snippet of code that I am working with:

import { GraphQLNonNull, GraphQLString, GraphQLList, GraphQLInt } from 'graphql';

import systemType from './type';
import { resolver } from 'graphql-sequelize';

let a = ({System}) => ({
  system: {
    type: systemType,
    args: {
      id: {
        description: 'ID of system',
        type: new GraphQLNonNull(GraphQLInt)
      }
    },
    resolve: resolver(System, {
      after: (result: any[]) => (result && result.length ? result[0] : result)
    })
  },
  systems: {
    type: new GraphQLList(systemType),
    args: {
      names: {
        description: 'List option names to retrieve',
        type: new GraphQLList(GraphQLString)
      },
      limit: {
        type: GraphQLInt
      },
      order: {
        type: GraphQLString
      }
    },
    resolve: resolver(System, {
      before: (findOptions: any, { query }: any) => ({
        order: [['name', 'DESC']],
        ...findOptions
      })
    })
  }
});

export = { a: a };

I'm encountering the TS7031 warning in VSCode:

Binding element 'System' implicitly has an 'any' type

Is there a way to address this warning?

Answer №1

It seems that TypeScript is unable to determine the type of the System value based on your code. To resolve this, you can simply provide an explicit type annotation like so:

let a = ({System}: { System: string }) => ({

});

Make sure to replace `string` with the correct type of the System parameter (perhaps something like `typeof systemType`?)
