What if you never have to write the –proxy-config CLI option again when serving your Angular application?

ng serve --proxy-config proxy.conf.json

Hmmm, what a sweet thought.

Well, it is possible. Angular makes it possible to specify a proxy configuration file in angular.json to serve with your application. So when next you run ng serve, it’s picked up automatically, no need typing ng serve --proxy-config proxy.conf.json.

To start using this, in the CLI configuration file, angular.json, add the proxyConfig option to the serve target:

"architect": {
  "serve": {
    "builder": "@angular-devkit/build-angular:dev-server",
    "options": {
      "browserTarget": "your-application-name:build",
      "proxyConfig": "src/proxy.conf.json"

To run the dev server with this proxy configuration, call ng serve ✌️.
