Ember serve custom header support

[Redsandro]

I would like to set a custom header to be served with every ember serve response. As far as I know, this is not possible.

ember serve <options...>
  Builds and serves your app, rebuilding on file changes.
  aliases: server, s
  --port (Number) (Default: 4200) To use a port different than 4200. Pass 0 to automatically pick an available port.
    aliases: -p <value>
  --host (String) Listens on all interfaces by default
    aliases: -H <value>
  --proxy (String)
    aliases: -pr <value>, -pxy <value>
  --proxy-in-timeout (Number) (Default: 120000) When using --proxy: timeout (in ms) for incoming requests
    aliases: -pit <value>
  --proxy-out-timeout (Number) (Default: 0) When using --proxy: timeout (in ms) for outgoing requests
    aliases: -pot <value>
  --secure-proxy (Boolean) (Default: true) Set to false to proxy self-signed SSL certificates
    aliases: -spr
  --transparent-proxy (Boolean) (Default: true) Set to false to omit x-forwarded-* headers when proxying
    aliases: --transp
  --watcher (String) (Default: events)
    aliases: -w <value>
  --live-reload (Boolean) (Default: true)
    aliases: -lr
  --live-reload-host (String) Defaults to host
    aliases: -lrh <value>
  --live-reload-base-url (String) Defaults to baseURL
    aliases: -lrbu <value>
  --live-reload-port (Number) Defaults to same port as ember app
    aliases: -lrp <value>
  --live-reload-prefix (String) (Default: _lr) Default to _lr
    aliases: --lrprefix <value>
  --environment (String) (Default: development) Possible values are "development", "production", and "test".
    aliases: -e <value>, -dev (--environment=development), -prod (--environment=production)
  --output-path (Path) (Default: dist/)
    aliases: -op <value>, -out <value>
  --ssl (Boolean) (Default: false) Set to true to configure Ember CLI to serve using SSL.
  --ssl-key (String) (Default: ssl/server.key) Specify the private key to use for SSL.
  --ssl-cert (String) (Default: ssl/server.crt) Specify the certificate to use for SSL.
  --path (Path) Reuse an existing build at given path.

Every now and then there's a good reason. For example, Chromium's mixed content experiment has Chrome and Chromium blocking http media requests on https sites.

In order to disable this non-standard behavior, you need to explain to all your customers that they need to opt-out from this experiment, or simply send a mixed-content: noupgrade header with the html content of your Ember site.

The same goes for FastBoot sites: ember-fastboot/fastboot-app-server#100

I wouldn't be apposed to accepting an addition that exposed this.

That being said, I suspect it can be accomplished, via someone inconvenient public API today, via in-repo add-on, that insert's itself into the express middleware chain.

Something like: https://github.com/ember-cli/ember-cli/blob/c97dee84155f05061868e34c44b250991127eba2/lib/tasks/server/middleware/broccoli-serve-files/index.js#L18

That also mimics the appropriate before/after clause to be "after: "broccoli-watcher": https://github.com/ember-cli/ember-cli/blob/master/lib/tasks/server/middleware/broccoli-serve-files/package.json#L6-L9

Interesting links. I did not now about ember-addons. Not much documentation.

Apparently, there is such a thing as /dist/_headers? See https://github.com/shipshapecode/ember-cli-netlify
