Most of the experimental handlers are ported to work with ion's handler form, from third-party sources.
| Middleware | Description | Example |
|---|---|---|
| jwt | Middleware checks for a JWT on the Authorization header on incoming requests and decodes it. |
get-ion/middleware/jwt/_example |
| cors | HTTP Access Control. | get-ion/middleware/cors/_example |
| secure | Middleware that implements a few quick security wins. | get-ion/middleware/secure/_example |
| tollbooth | Generic middleware to rate-limit HTTP requests. | get-ion/middleware/tollbooth/_examples/limit-handler |
| cloudwatch | AWS cloudwatch metrics middleware. | get-ion/middleware/cloudwatch/_example |
| new relic | Official New Relic Go Agent. | get-ion/middleware/newrelic/_example |
| prometheus | Easily create metrics endpoint for the prometheus instrumentation tool | get-ion/middleware/prometheus/_example |
ion has its own middleware form of func(ctx context.Context) but it's also compatible with all net/http middleware forms. See here.
