# `Nous.HTTP.Backend.Hackney`
[🔗](https://github.com/nyo16/nous/blob/v0.17.1/lib/nous/http/backend/hackney.ex#L1)

`Nous.HTTP.Backend` implementation backed by `:hackney`.

Uses `:hackney.request/5` synchronously — hackney 4 returns the full
response body inline as `{:ok, status, headers, body}` (the legacy
`hackney.body/1` follow-up call from hackney 1.x was removed in v4).
Hackney 4 is already in the dependency tree from 0.15.0 (used for
streaming) — this backend lets users consolidate non-streaming HTTP
onto the same library without keeping Finch/Mint in the hot path.

TLS verification mirrors the streaming side: explicit
`verify: :verify_peer` with system CAs from `:public_key.cacerts_get/0`.
Hackney's default is `:verify_none`, which would silently accept
MITM'd connections — do not regress this.

Pool: uses hackney's `:default` pool (50 conns, 2s idle keepalive).
Apps that want isolation can pass `pool: :my_pool` per call after
starting the pool with `:hackney_pool.start_pool/2`.
