Deploying an application

Deploying your application is the process of compiling, or building, your code and hosting the JavaScript, CSS, and HTML on a web server.

This section builds on the previous steps in the Getting Started tutorial and shows you how to deploy your application.

Prerequisites

A best practice is to run your project locally before you deploy it. To run your project locally, you need the following installed on your computer:

• Node.js.

• The Angular CLI. From the terminal, install the Angular CLI globally with:

  npm install -g @angular/cli
  

  With the Angular CLI, you can use the command ng to create new workspaces, new projects, serve your application during development, or produce builds to share or distribute.

Running your application locally

1. Download the source code from your StackBlitz project by clicking the Download Project icon in the left menu, across from Project, to download your files.

2. Create a new Angular CLI workspace using the ng new command, where my-project-name is what you would like to call your project:

   ng new my-project-name
   

   This command displays a series of configuration prompts. For this tutorial, accept the default settings for each prompt.

3. In your newly CLI-generated application, replace the /src folder with the /src folder from your StackBlitz download.

4. Use the following CLI command to run your application locally:

   ng serve
   

5. To see your application in the browser, go to http://localhost:4200/. If the default port 4200 is not available, you can specify another port with the port flag as in the following example:

   ng serve --port 4201
   

   While serving your application, you can edit your code and see the changes update automatically in the browser. To stop the ng serve command, press Ctrl+c.

Building and hosting your application

1. To build your application for production, use the build command. By default, this command uses the production build configuration.

   ng build
   

   This command creates a dist folder in the application root directory with all the files that a hosting service needs for serving your application.

   If the above ng build command throws an error about missing packages, append the missing dependencies in your local project's package.json file to match the one in the downloaded StackBlitz project.

2. Copy the contents of the dist/my-project-name folder to your web server. Because these files are static, you can host them on any web server capable of serving files; such as Node.js, Java, .NET, or any backend such as Firebase, Google Cloud, or App Engine.
