Hello,
I'm looking for an HTML filter as the one written for Nginx : [ngx\_http\_sub\_module](http://nginx.org/en/docs/http/ngx_http_sub_module.html)
The goal here is to inject javascript in the Traefik response
Is there any middleware available for that ?
Florian

You can find the list of available middleware for traefik on the [documentation site](https://docs.traefik.io/middlewares/overview/), look at the sidebar on the left.

From what I have seen, there is no middlewares available for that, did I miss something ?
I found that Traefik 2.3 can handle plugins, and the plugin [rewrite body](https://github.com/containous/plugin-rewritebody) could solve my issue. However the docs says that this is only available through Traefik Pilot Saas software.

Probably not.

The plugins are available in Traefik (OSS) through Traefik Pilot (the plugins registry)
