Barrel API Shape

A barrel module gathers selected exports into a small public surface.

barrel_api.ts

function normalizeName(name: string): string {
    return name.trim().toLowerCase();
}

function formatUser(name: string, admin: boolean): string {
    const role: string = admin ? "admin" : "reader";
    return `${normalizeName(name)}:${role}`;
}

export const publicApi = {
    formatUser,
};

const admin: boolean = ;
const line: string = publicApi.formatUser(" ADA ", admin);

console.log(line);

function normalizeName(name: string): string {
    return name.trim().toLowerCase();
}

function formatUser(name: string, admin: boolean): string {
    const role: string = admin ? "admin" : "reader";
    return `${normalizeName(name)}:${role}`;
}

export const publicApi = {
    formatUser,
};

const admin: boolean = ;
const line: string = publicApi.formatUser(" ADA ", admin);

console.log(line);

barrel module A barrel file re-exports a curated set of names so callers do not depend on every internal file.
