Code

import { emailTemplates } from './utils/email';

const defaultOptions = {
  tokenSecret: 'secret',
  tokenConfigs: {
    accessToken: {
      expiresIn: '90m',
    },
    refreshToken: {
      expiresIn: '7d',
    },
  },
  // Type is inferred here
  emailTemplates,
  userObjectSanitizer: (user: User) => user,
  sendMail,
  siteUrl: 'http://localhost:3000',
};

Expected behavior:

// ...
import { EmailTemplateType } from './types/email-template-type';
declare const defaultOptions: {
    tokenSecret: string;
    tokenConfigs: {
        accessToken: {
            expiresIn: string;
        };
        refreshToken: {
            expiresIn: string;
        };
    };
    emailTemplates: EmailTemplateType;
    userObjectSanitizer: (user: User) => User;
    sendMail: (mail: object) => Promise<void>;
    siteUrl: string;
};
// ...

Actual behavior:

// ...
import { EmailTemplateType } from './types/email-template-type';
declare const defaultOptions: {
    tokenSecret: string;
    tokenConfigs: {
        accessToken: {
            expiresIn: string;
        };
        refreshToken: {
            expiresIn: string;
        };
    };
    emailTemplates: import("@accounts/server/src/types/email-templates-type").EmailTemplatesType;
    userObjectSanitizer: (user: User) => User;
    sendMail: (mail: object) => Promise<void>;
    siteUrl: string;
};
// ...

How to reproduce:

• git clone https://github.com/accounts-js/accounts
• cd accounts
• Setup the repo, run yarn
• Setup lerna, run yarn setup
• Then compile with tsc, run yarn compile
• Open packages/server/lib/accounts-server.d.ts to see the error

Happy to provide more infos if needed thanks :)

Looks like compiling your repro with typescript@next is currently blocked by #26978.
