ng e2e - wiki update

[Bartosz-D3V]

It is possible to pass proxy-config parameter when running ng e2e command like this:
ng e2e --proxy-config proxy.conf.json
This is the same parameter as when running ng serve command, nevertheless it is not documented in the wiki:
https://github.com/angular/angular-cli/wiki/e2e

I personally think that it would save some developers time, when configuring protractor to run against the real backend, that requires proxy.
If the missed argument in the wiki is desired - is there any reason not to pass the argument just like we do when running ng serve?

Up to Angular 5, the parameter --proxy-config was working for both ng serve and ng e2e. Now it doesn't work anymore for ng e2e.

If anyone else stumbles on this wondering how to use a proxy for e2e-tests in Angular 6 then this is now done in the angular.json file by configuring the serve option used by your e2e tests devServerTarget and adding the proxyConfig to your options.

For example I have e2e tests for angular-login with the following configuration:

"angular-login-e2e": {
  "root": "e2e/",
  "projectType": "application",
  "architect": {
    "e2e": {
      "builder": "@angular-devkit/build-angular:protractor",
      "options": {
        "protractorConfig": "e2e/protractor.conf.js",
        "devServerTarget": "angular-login:serve"
      }
    }
  }
}

The devServerTarget option refers to angular-login:serve which is the webpack dev server which will be started.

What you want to do is to add the proxyConf option to that dev server. In my angular-login's serve I have included proxyConfig under options, which will work the same way as before:

"serve": {
  "builder": "@angular-devkit/build-angular:dev-server",
  "options": {
    "browserTarget": "angular-login:build",
    "proxyConfig": "proxy.conf.json",
  },
  "configurations": {
    "production": {
      "browserTarget": "angular-login:build:production"
    }
  }
}

Is it possible to set the value of proxyConfig dynamically? We are currently creating a dynamic proxy config file in a temp folder for CI runs.

[mbark]

@plurch would it work to create a symlink from proxy.conf.json to the dynamically created one in the temporary directory?

[plurch]

Thanks for the suggestion, @mbark . Seems like that would work. We decided to just overwrite the same proxy.conf.json file directly.
