+# Serving Angular apps for development
+
+You can serve your Angular CLI application with the `ng serve` command.
+This will compile your application, skip unnecessary optimizations, start a devserver, and automatically rebuild and live reload any subsequent changes.
+You can stop the server by pressing `Ctrl+C`.
+
+`ng serve` only executes the builder for the `serve` target in the default project as specified in `angular.json`.
+While any builder can be used here, the most common (and default) builder is `@angular-devkit/build-angular:dev-server`.
+
+You can determine which builder is being used for a particular project by looking up the `serve` target for that project.

+## Proxying to a backend server
+
+Use [proxying support](https://webpack.js.org/configuration/dev-server/#devserverproxy) to divert certain URLs to a backend server, by passing a file to the `--proxy-config` build option.
+For example, to divert all calls for `http://localhost:4200/api` to a server running on `http://localhost:3000/api`, take the following steps.
+
+1. Create a file `proxy.conf.json` in your project's `src/` folder.
+1. Add the following content to the new proxy file:
+
+    <docs-code language="json">
+
+    {
+      "/api": {
+        "target": "http://localhost:3000",
+        "secure": false
+      }
+    }
+
+    </docs-code>
+
+1. In the CLI configuration file, `angular.json`, add the `proxyConfig` option to the `serve` target:
+
+    <docs-code language="json">
+
+    {
+      "projects": {
+        "my-app": {
+          "architect": {
+            "serve": {
+              "builder": "@angular-devkit/build-angular:dev-server",
+              "options": {
+                "proxyConfig": "src/proxy.conf.json"
+              }
+            }
+          }
+        }
+      }
+    }
+
+    </docs-code>
+
+1. To run the development server with this proxy configuration, call `ng serve`.
+
+Edit the proxy configuration file to add configuration options; following are some examples.
+For a detailed description of all options, refer to the [webpack DevServer documentation](https://webpack.js.org/configuration/dev-server/#devserverproxy) when using `@angular-devkit/build-angular:browser`, or the [Vite DevServer documentation](https://vite.dev/config/server-options#server-proxy) when using `@angular-devkit/build-angular:browser-esbuild` or `@angular-devkit/build-angular:application`.
+
+NOTE: If you edit the proxy configuration file, you must relaunch the `ng serve` process to make your changes effective.
+
+## `localhost` resolution
+
+As of Node version 17, Node will _not_ always resolve `http://localhost:<port>` to `http://127.0.0.1:<port>`
+depending on each machine's configuration.
+
+If you get an `ECONNREFUSED` error using a proxy targeting a `localhost` URL,
+you can fix this issue by updating the target from `http://localhost:<port>` to `http://127.0.0.1:<port>`.
+
+See [the `http-proxy-middleware` documentation](https://github.com/chimurai/http-proxy-middleware#nodejs-17-econnrefused-issue-with-ipv6-and-localhost-705)
