Input Normalization Case

A small normalization step can clean user input before later code stores or routes it.

normalize.ts

type NormalizedUser = {
    displayName: string;
    slug: string;
};

function normalizeUser(rawName: string): NormalizedUser {
    const trimmed: string = rawName.trim();
    const displayName: string = trimmed.replace(/\s+/g, " ");
    const slug: string = displayName.toLowerCase().replace(/\s+/g, "-");

    return { displayName, slug };
}

const rawName: string = ;
const user: NormalizedUser = normalizeUser(rawName);

console.log(`name=${user.displayName};slug=${user.slug}`);

type NormalizedUser = {
    displayName: string;
    slug: string;
};

function normalizeUser(rawName: string): NormalizedUser {
    const trimmed: string = rawName.trim();
    const displayName: string = trimmed.replace(/\s+/g, " ");
    const slug: string = displayName.toLowerCase().replace(/\s+/g, "-");

    return { displayName, slug };
}

const rawName: string = ;
const user: NormalizedUser = normalizeUser(rawName);

console.log(`name=${user.displayName};slug=${user.slug}`);

input normalization Normalize early so the rest of the pipeline sees a predictable typed record.
