config/config.default.ts
export interface Config {
keys: string
news: {
pageSize: number;
};
}
export type PowerPartial<T> = {
[U in keyof T]?: T[U] extends {}
? PowerPartial<T[U]>
: T[U]
}
// for config.{env}.ts
export type DefaultConfig = PowerPartial<Config>;config.local.ts
import { DefaultConfig } from './config.default';
export default () => {
const config: DefaultConfig = {};
config.sourceUrl = 'foo'
config.news = {
pageSize: 20,
};
return config;
}; got error:
config/config.local.ts(3,1): error TS4082: Default export of the module has or is using private name 'PowerPartial'.
config/config.local.ts(6,10): error TS2339: Property 'sourceUrl' does not exist on type 'PowerPartial<Config>'.
11:06:36 - Compilation complete. Watching for file changes.
if change to `"declaration": false,``` , then issue gone.
any suggestion ?
