Typescript: TS7006: Parameter ‘xxx’ implicitly has an ‘any’ type

You are using the --noImplicitAny and TypeScript doesn’t know about the type of the Users object. In this case, you need to explicitly define the user type.

Change this line:

let user = Users.find(user => user.id === query);

to this:

let user = Users.find((user: any) => user.id === query); 
// use "any" or some other interface to type this argument

Or define the type of your Users object:

//...
interface User {
    id: number;
    name: string;
    aliases: string[];
    occupation: string;
    gender: string;
    height: {ft: number; in: number;}
    hair: string;
    eyes: string;
    powers: string[]
}
//...
const Users = <User[]>require('../data');
//...
