Example from readme with typescript

[kevinsimper]

I tried the example and it does not seem to compile

import Conf from 'conf'

const schema = {
	bar: {
		type: 'string'
	}
};

const config = new Conf({schema});

Can you reproduce this with the latest TypeScript version?

We have a type test for this:

conf/test/index.test-d.ts

Lines 35 to 56 in 1dcfd0d

	new Conf<UnicornFoo>({
	schema: {
	foo: {
	type: 'string',
	default: 'foobar'
	},
	unicorn: {
	type: 'boolean'
	},
	hello: {
	type: 'number'
	},
	nested: {
	type: 'object',
	properties: {
	prop: {
	type: 'number'
	}
	}
	}
	}
	});

@sindresorhus I clone the repo and it is appearently down to how you define the schema, I am really confused: #121

The same error here: https://travis-ci.com/github/sindresorhus/conf/jobs/370496506

[sneljo1]

Located the issue, we expected the schema to by typed like const schema: Schema<UnicornFoo>, but we should also allow standard objects for people who do not want to explicitly type it.
