inconsistent string template exports in type interface files

[aappddeevv]

TypeScript Version: 3.8.3

Code

export const strange = `no interpolated values`
export const interpolated = `has interpolated ${some_value} values`

Expected behavior:

export declare const strange: string
export declare const interpolated: string

Actual behavior:

export declare const strange = "no interpolated values"
export declare const interpolated: string

I could not determine if this was expected but it seemed inconsistent.

This is by design. See: #16592

The first version is a constant because it contains no interpolated values. That means a more strict type (the string literal type) can be inferred.

As a workaround you can set the type explicitly:

export const strange: string = `no interpolated values`
