Middleware

Rewrite

Rewrite exact or wildcard paths before route dispatch.

Rewrite changes the request path before routing, without telling the client. Use it to serve old URLs from new handlers, or to alias one path to another.

app.Use(middleware.Rewrite("/old", "/new"))

The client does not receive a redirect. Handlers see the rewritten path.

Wildcard rewrites use * in the source and destination.

app.Use(middleware.RewriteWithRules(map[string]string{
  "/v1/*": "/api/v1/*",
}))

Use RewriteWithConfig when a Skipper is needed.
