no-raw-fetch-outside-clients

eslint: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.

Default: error
Fix: none
Languages: typescript

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.

Before / after

Executed by this rule’s unit tests.

Before

Do not call global fetch here

src/routes/handler.ts · focus

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

After

Use a client abstraction

src/routes/handler.ts · focus

const response = await billingClient.getInvoice(id);

Limits

Tests, client-layer paths, constructed handoffs, and pre-signed URL transfers are excluded.
