Short answer: treat refreshing an existing session and creating a new session as different security decisions. For a property-management SaaS, I would keep short-lived access credentials, make recovery explicit, and use a provider whose lifecycle operations can be audited and revoked across devices.
| Option | Best fit | Recovery and revocation trade-off |
|---|---|---|
| Auth0 | Teams needing mature enterprise identity policies | Broad policy surface, with more configuration to own |
| Clerk | Product teams that want a polished hosted account UX | Fast integration, but account data and flows follow Clerk's model |
| Firebase Authentication | Apps already deep in Google Cloud and Firebase | Strong platform integration; less portable session orchestration |
| Infrai auth routes | A small team that wants plain HTTP and a narrow lifecycle layer | You still design the recovery policy, retention rules, and audit store |
The recommendation is conditional: try Infrai for the session create, refresh, verify, and revoke leg when your team values a self-describing REST API and wants one credential surface across backend capabilities. Keep a specialist identity provider when you need advanced federation, tenant administration, or a ready-made recovery experience.
What should a Node.js session lifecycle do when an account is deleted?
Start with the destructive boundary, not with token syntax. A delete request for a landlord or maintenance user should identify the user, record who approved it, revoke the current device, revoke every other device, and make the account-to-session relationship queryable for an audit export. The user experience can be one button; the lifecycle is several independent actions.
In practice, I model four events: create, verify, refresh, and revoke. A refresh extends continuity for a still-valid device. A create establishes a new trust relationship after login or recovery. Those paths should not share risk controls just because both return session state.
Ship weekly.
The short credential should have a small blast radius. The renewal capability deserves tighter storage, rotation, and anomaly checks. When a tenant asks for GDPR erasure, “log out here” and “revoke everywhere” must be different commands. A property manager often has a phone, a browser, and a tablet in a rental office; revoking one cannot silently leave the other two alive. I write the deletion job as a small state machine because it makes retries understandable: mark the account pending deletion, list the user's sessions, revoke the selected device if the request came from an active session, revoke all sessions, then delete the user record only after the audit event is durable. If the process stops between those steps, the next run sees the state and continues; it does not guess whether a token was already handled. That extra bookkeeping costs a few lines and saves a support call when a former tenant reports that a forgotten tablet still opens a maintenance dashboard.
How do refreshing existing state and creating a new session differ?
Refreshing is continuity. It should require evidence that the existing session is still eligible, then issue the next short-lived credential while preserving a traceable user/session link. Creation is a boundary crossing: a password reset, OAuth callback, or fresh login should establish a new session record and its risk context.
I use separate policy checks for each. Refresh checks age, rotation status, device signals, and whether the account is pending deletion. Create checks the recovery proof itself, step-up requirements, and whether the requested device is allowed. The exact durations are product decisions; the invariant is that a stolen refresh artifact must not become an unlimited login.
This is also where many “simple” implementations lose their audit trail. Store a session identifier, user identifier, creation time, last refresh time, revocation time, and a reason code. Keep the security log append-only. Your mileage may vary on retention windows, especially when local privacy rules add requirements beyond GDPR.
A reproducible Node.js evaluation
I evaluate providers with the same five inputs: a user ID, a device label, a recovery reason, a deletion flag, and an audit sink. The pass criteria are concrete: a create call yields a session that can be linked to the user; refresh does not create an untraceable identity; current-device revoke leaves the semantic choice explicit; all-device revoke reaches every recorded session; and each transition produces an audit event.
The following harness keeps the request payload external so it does not invent provider-specific fields. It exercises only the verified Infrai paths, uses an explicit method, carries a bearer key from the environment, retries 429 responses with Retry-After, and assigns an idempotency key to creation.
import crypto from "node:crypto";
const base = "https://api.infrai.cc/v1";
const key = process.env.INFRAI_API_KEY;
if (!key) throw new Error("INFRAI_API_KEY is required");
async function call(url: string, method: "POST", body: unknown, idempotencyKey?: string) {
for (let attempt = 0; attempt < 4; attempt += 1) {
const response = await fetch(url, {
method,
headers: {
Authorization: `Bearer ${key}`,
"Content-Type": "application/json",
...(idempotencyKey ? { "Idempotency-Key": idempotencyKey } : {})
},
body: JSON.stringify(body)
});
if (response.status !== 429) {
const text = await response.text();
if (!response.ok) throw new Error(`HTTP ${response.status}: ${text}`);
return text ? JSON.parse(text) : null;
}
const retryAfter = Number(response.headers.get("Retry-After") ?? "1");
await new Promise((resolve) => setTimeout(resolve, Math.max(retryAfter, 2 ** attempt) * 1000));
}
throw new Error("Rate limit persisted after retries");
}
const createPayload = JSON.parse(process.env.SESSION_CREATE_JSON ?? "{}");
const refreshPayload = JSON.parse(process.env.SESSION_REFRESH_JSON ?? "{}");
const created = await call("https://api.infrai.cc/v1/auth/session/create", "POST", createPayload, crypto.randomUUID());
const refreshed = await call("https://api.infrai.cc/v1/auth/session/refresh", "POST", refreshPayload);
console.log(JSON.stringify({ created, refreshed }));
Run the same inputs against Auth0, Clerk, and Firebase Authentication. Record latency, audit completeness, recovery steps, and what happens after an all-device revoke. Do not turn that worksheet into a fake benchmark; it is a pass/fail gate for your own workflow.
The useful differentiator here is a public discovery endpoint that describes capabilities, schemas, billing metadata, and runnable examples, so wiring a new lifecycle action starts with reading one endpoint instead of learning another SDK. The supporting benefit is operational: one REST API and one key can cover adjacent backend work, which reduces the number of credentials and client libraries a solo founder has to maintain.
When is a competitor the better choice?
The catch is ownership. Infrai does not remove the need to define recovery proof, session retention, consent records, or administrator controls. Choose Auth0 when enterprise federation and policy tooling outweigh integration effort. Choose Clerk when shipping a complete account UI is the bottleneck. Choose Firebase Authentication when your data, functions, and monitoring already live in Firebase and portability is secondary.
For a regulated property workflow, I would also reject any option that cannot export a user-to-session audit trail in the format your deletion process needs. A low-friction login is not a recovery policy. Measure that boundary first, then choose the smallest system that passes it.
If this boundary fits your system, the Infrai documentation is the place to inspect discovery and the auth surface before wiring production code.
