If you are building a universal app, you can quickly deploy your web app using [EAS Hosting](/eas/hosting/introduction/). It is a service for deploying web apps built with Expo Router and React. ## Prerequisites Before you begin, in your project's **app.json** file, ensure that the [`expo.web.output`](/versions/latest/config/app/#output) property is either `static` or `server`. ## Export your web project To deploy your web app, you need to create a static build of your web project. Export your web project into a **dist** directory by running the following command: > Remember to re-run this command every time before deploying when you make changes to your web app. ## Initial deployment To publish your web app, run the following [EAS CLI](/develop/tools/#eas-cli) command: After running this command for the first time, you'll be prompted to select a preview subdomain for your project. This subdomain is a prefix used to create a preview URL and is used for production deployments. For example, in `https://test-app--1234.expo.app`, `test-app` is the preview subdomain. Once your deployment is complete, the EAS CLI will output a preview URL to access your deployed app. ## Production deployment To create a production deployment, run the following [EAS CLI](/develop/tools/#eas-cli) command: Once your deployment is complete, the EAS CLI will output a production URL to access your deployed app. ## Deploy automatically You can automatically deploy your app to the web with [EAS Workflows](/eas/workflows/get-started/). First, you'll need to [configure your project](/eas/workflows/get-started/#configure-your-project), add a file named **.eas/workflows/deploy-web.yml** at the root of your project, then add the following workflow configuration: ```yaml .eas/workflows/deploy-web.yml name: Deploy web on: push: branches: ['main'] jobs: deploy_web: name: Deploy web type: deploy params: prod: true ``` The workflow above will create a web deployment on every commit to your project's `main` branch. You can also run this workflow manually with the following EAS CLI command: Learn more about common patterns with the [workflows examples guide](/eas/workflows/examples). ## Learn more You can learn more about setting up [deployment aliases](/eas/hosting/deployments-and-aliases/), using a [custom domain](/eas/hosting/custom-domain/), or [deploying an API Route](/router/reference/api-routes/#deployment).
