no-raw-fetch-outside-clients

Disallow calling the global fetch outside the client layer; route outbound HTTP through a client module that owns retry, timeout and status handling.

rawFetch Rule source Tests Catalog JSON

Why

Scattered fetch calls bypass shared transport policy and are harder to stub and observe consistently.

Fix

Move the request into a client module and call that abstraction from application code.

Examples

Before — flagged Do not call global fetch here

src/routes/handler.ts

const response = await fetch("/api/invoices");

After — preferred Use a client abstraction

src/routes/handler.ts

const response = await billingClient.getInvoice(id);
