+# Run Multiple Node Scripts Concurrently
+
+The [`concurrently` npm
+package](https://github.com/open-cli-tools/concurrently) is a CLI for
+concurrently running multiple commands or scripts. This is great for working in
+the context of a web server development where you often need several pieces of
+infrastructure running locally at once.
+
+Assuming you have the `concurrently` package installed and there are several
+dev scripts in your `package.json`, here is one way this could look:
+
+```json
+{
+  "scripts": {
+    "dev": "concurrently \"npm run dev:next\" \"npm run dev:inngest\" \"npm run dev:mailhog\"",
+    "dev:next": "next dev",
+    "dev:inngest": "pnpx inngest-cli@latest dev",
+    "dev:mailhog": "mailhog",
+  }
+}
+```
+
+Running `npm run dev` would start a process that runs all three commands and
+combines their output.
+
+A shorthand way of writing this since these commands all have the same prefix
+is:
+
+```json
+{
+  "scripts": {
+    "dev": "concurrently \"npm:dev:*\"",
+    "dev:next": "next dev",
+    "dev:inngest": "pnpx inngest-cli@latest dev",
+    "dev:mailhog": "mailhog",
+  }
+}
+```
