Thin wrapper around the amp-optimizer
npm install toolbox-optimizer-dockeramp-optimizer-docker is a Docker container that exposes an AMP Optimizer server for optimizing your amphtml using the same server-side-rendering optimizations as the Google AMP Cache.
The AMP Optimizer server accepts POST requests at port 3000 and requires an HTML body. It then runs the HTML through the optimizer package, and returns the result as the response.
There are two different kinds of configuration you can supply to the container:
1. Static configuration via environment variables: On startup, the container will search for environment variables prefixed with AMP_OPTIMIZER_ and pass the values as configuration options when initializing the underlying optimizer library. The full list of options are available here. Options should be specified in SCREAMING_SNAKE_CASE as opposed to camelCase. For example, in order to configure the preloadHeroImage option, you would declare the environment variable named: AMP_OPTIMIZER_PRELOAD_HERO_IMAGE.
2. Per-request configuration: there are some options that can only be set on a per-request basis. For example, the canonical flag for specifying an AMP page's canonical link. These can be specified via query params, e.g. /?canonical=http://example.com.
via:
```
$ docker pull amp-toolbox-docker-optimizer
$ docker run -it amp-toolbox-docker-optimizer
The amp-toolbox-docker-optimizer image can be layered and composed using any of the usual container orchestration tools, like Docker Compose or Kubernetes. An example of using Docker Compose is provided under the demo` directory.
To achieve best performance, transformations shouldn't be applied for
every request. Instead, transformations should only be applied the first time
a page is requested, and the results then cached. Caching can happen on the CDN
level, on the site's internal infrastructure (e.g.: Memcached), or even on the
server itself, if the set of pages is small enough to fit in memory.
