Auth-specific middleware moves to github.com/hanzoai/gateway/middleware. Other subsystems mounted in cloud trust gateway-minted X-Org-Id headers and do not re-validate JWTs themselves. zip's middleware kit keeps the generic concerns: Recover, Logger, RequestID, Timeout, MaxBody, CORS, RateLimit, Telemetry. Subsystems that need to assert gateway-minted state import github.com/hanzoai/gateway and call gateway.AssertGatewayMinted(c).

zip middleware
Generic middleware for the zip framework. Auth-specific middleware
(JWT validation, identity-header stripping) lives in
github.com/hanzoai/gateway/middleware
— see "Why auth lives in gateway" below.
Available middleware
| Name | Purpose |
|---|---|
Recover() |
panic → JSON 500 |
Logger(luxlog.Logger) |
request log via luxfi/log |
RequestID() |
X-Request-Id propagation |
Timeout(d) |
per-request ctx deadline |
MaxBody(n) |
request size limit |
CORS(opts) |
standard CORS |
RateLimit(opts) |
per-key token bucket |
Telemetry(o11yClient) |
OTel span + request metrics |
Why auth lives in gateway
JWT validation + identity-header minting are the responsibility of the
gateway subsystem (per HIP-0106). Other subsystems mounted inside the
unified cloud binary trust the gateway-minted X-Org-Id header and do
NOT re-validate JWTs themselves — re-running JWT validation per-subsystem
is wasteful and risks divergent validation rules.
Subsystems that need to ASSERT the request was gateway-minted import
github.com/hanzoai/gateway and call gateway.AssertGatewayMinted(c).
Pipeline order
Recommended order for a service that mounts zip behind hanzoai/gateway:
app.Use(
middleware.Recover(), // 1. always first
middleware.RequestID(), // 2. mint request id
middleware.Logger(app.Logger()), // 3. log with request id
middleware.Telemetry(o11y), // 4. metrics
middleware.RateLimit(rlCfg), // 5. limit
middleware.CORS(corsCfg), // 6. last — close to response
)
JWT validation + identity-header stripping/minting is owned by the
gateway subsystem; see
github.com/hanzoai/gateway/middleware.
