Auth template posted
What happened
A practical authentication prompt template for production Next.js or Express apps was shared, emphasising secure JWT usage with refresh rotation, bcrypt password hashing, httpOnly cookies, rate limiting, and input validation. The post presents concrete patterns you can copy into portfolio projects that need robust auth flows (x.com).
Why it matters
The post was published on X by Harshil Tomar, who uses the handle @Hartdrawss and publishes developer templates and practical engineering prompts; the original share is at the X status link. (x.com) (github.com) Tomar’s timeline regularly pushes operational checklists and reusable code patterns — for example he recently posted an "API audit" prompt that instructs developers to add schema validation (he names Zod, a TypeScript-friendly validation library) to every route. (t.co) The template’s core terms map to concrete safeguards: "refresh token rotation" means issuing a fresh long-lived token each time the client uses a refresh endpoint so a stolen old token can’t be reused; this is the rotation pattern used by major providers. (auth0.com) "Bcrypt" is a password-hashing algorithm that deliberately slows hashing to make brute-force attacks expensive; recommended cost parameters are commonly in the 10–12 rounds range to balance security and latency. (passlib.readthedocs.io) An "HttpOnly" cookie is a browser cookie that client-side JavaScript cannot read, which helps prevent token theft via injected scripts; production guidance also points to setting Secure and SameSite flags so the browser only sends the cookie over encrypted connections and limits cross-site sending. (developer.mozilla.org) Rate limiting is the practice of capping how many requests a single client can make in a time window (for example 100 requests per 15 minutes) to stop brute force and denial‑of‑service patterns; the most-used Express middleware for that is express-rate-limit. (github.com) (owasp.org) Concrete production details the community recommends and the template’s description implies: hash refresh tokens in your database (store the hash, not the raw token) so a DB leak doesn't hand attackers valid tokens; rotate and revoke refresh tokens on use; keep access tokens short‑lived and use a separate refresh token flow for session continuity. (freecodecamp.org) (developer.okta.com) Official Next.js and Auth tooling documentation and modern community templates converge on these choices for production-ready apps, so copying the template’s patterns into a portfolio project yields the same structural decisions used by widely referenced guides.
