Com um app Next.js ou Angular (versões 13.5.x+ do Next.js ou 18.2.x+ do Angular) em um repositório do GitHub, começar a usar o App Hosting é tão simples quanto criar um back-end App Hosting e iniciar um lançamento com um push para sua ramificação ativa. Se você não tiver um app, use um dos
nossos apps de exemplo para seguir as etapas descritas neste guia.
Antes de começar
Antes de configurar o Firebase App Hosting, crie um projeto do Firebase (se ainda não tiver um) e faça upgrade para o plano Blaze.
Etapa 0 (opcional): criar um repositório do GitHub e um web app
Se você ainda não tiver um app da Web em um repositório do GitHub ou se preferir testar o fluxo com um app de exemplo, comece inicializando uma das nossas amostras para Next.js ou Angular:
npm init @apphosting
É possível executar o app de amostra localmente usando next dev ou ng start. Para continuar, crie um repositório do GitHub e envie o código de amostra recém-inicializado para ele.
Etapa 1: criar um back-end App Hosting
Um back-end do App Hosting é a coleção de recursos gerenciados que o
App Hosting cria para criar e executar seu app da Web.
Console do Firebase: no menu Build, selecione App Hosting e clique em
Começar agora.
CLI: (versão 13.15.4 ou mais recente) para criar um back-end, execute o seguinte
comando na raiz do diretório do projeto local, fornecendo seu
projectID como um argumento:
No console ou na CLI, siga as instruções para escolher uma região, configurar uma conexão do GitHub e definir estas configurações básicas de implantação:
Defina o diretório raiz do app (o padrão é /)
É onde o arquivo package.json geralmente está localizado.
Defina a ramificação ativa
Esse é o branch do seu repositório do GitHub que é implantado no seu
URL ativo. Muitas vezes, é a ramificação em que as ramificações de recursos ou de desenvolvimento são mescladas.
Aceitar ou recusar lançamentos automáticos
Os lançamentos automáticos são ativados por padrão. Ao concluir a criação do back-end,
você pode escolher implantar o app em App Hosting imediatamente.
Atribua um nome ao back-end.
Etapa 2: conferir o app implantado
Ao criar um back-end, o Firebase oferece um subdomínio sem custos financeiros em que os usuários finais podem acessar seu app da Web. O formato é backend-id--project-id.us-central1.hosted.app.
Para conferir o URL do seu app da Web, verifique o console do Firebase ou execute o seguinte comando da CLI:
Etapa 3: acionar um lançamento enviando uma mudança
Depois que o back-end for criado e você tiver um URL ativo, será possível
acionar o lançamento de uma nova versão do seu web app sempre que enviar
mudanças para a ramificação ativa do repositório do GitHub. Para fazer um teste da configuração do App Hosting:
No GitHub, envie uma mudança para o branch ativo do web app.
Abra a
guia App Hosting no
console do Firebase e selecione Ver painel para seu back-end.
A lista de tabelas mostra o commit específico associado ao lançamento
acionado pela sua mudança.

[null,null,["Última atualização 2025-08-23 UTC."],[],[],null,["\u003cbr /\u003e\n\nWith an existing Next.js or Angular app (Next.js versions 13.5.x+\nor Angular 18.2.x+)\nin a GitHub repository, getting started with App Hosting can be as\nstraightforward as creating an App Hosting backend and then starting a\nrollout with a push to your live branch. If you don't have an app, use one of\nour sample apps to walk through the steps described in this guide.\n\nBefore you begin\n\nBefore you can set up Firebase App Hosting, you'll need to create a Firebase\nproject (if you don't already have one) and upgrade to the Blaze plan.\n\nTo create a project:\n\nNew to Firebase or Cloud\n\n\nFollow these steps if you're new to Firebase or Google Cloud. \n\nYou can also follow these steps if you want to create a wholly new\nFirebase project (and its underlying Google Cloud project).\n\n1. Sign into the [Firebase console](//console.firebase.google.com/).\n2. Click the button to create a new Firebase project.\n3. In the text field, enter a **project name**.\n\n If you're part of a Google Cloud org, you can optionally select which\n folder you create your project in.\n | Your project name is used as a display name in Firebase interfaces, and Firebase auto-creates a unique project ID based on this project name. Note that you can optionally click the **Edit** icon now to set your preferred project ID, but you cannot change this ID after project creation. Learn about [how Firebase uses the\n | project ID](/docs/projects/learn-more#project-id).\n4. If prompted, review and accept the [Firebase terms](/terms), then click **Continue**.\n5. *(Optional)* Enable AI assistance in the Firebase console (called \"Gemini in Firebase\"), which can help you get started and streamline your development process.\n6. *(Optional)* Set up Google Analytics for your project,\n which enables an optimal experience using these Firebase products:\n [Firebase A/B Testing](/docs/ab-testing),\n [Cloud Messaging](/docs/cloud-messaging),\n [Crashlytics](/docs/crashlytics),\n [In-App Messaging](/docs/in-app-messaging), and\n [Remote Config](/docs/remote-config)\n (including\n [Personalization](/docs/remote-config/personalization)).\n\n Either select an existing\n [Google Analytics account](//support.google.com/analytics/answer/1009618)\n or create a new account. If you create a new account, select your\n [Analytics reporting location](/docs/projects/locations),\n then accept the data sharing settings and Google Analytics terms\n for your project.\n | You can always set up Google Analytics later in the [*Integrations* tab](//console.firebase.google.com/project/_/settings/integrations) of your settings *Project settings*.\n7. Click **Create project**.\n\nFirebase creates your project, provisions some initial resources, and\nenables important APIs. When the process completes, you'll be taken to the\noverview page for your Firebase project in the Firebase console.\n\nExisting Cloud project\n\n\nFollow these steps if you want to start using Firebase with an existing\nGoogle Cloud project. Learn more about\n[\"adding\nFirebase\" to an existing Google Cloud project](/docs/projects/use-firebase-with-existing-cloud-project).\n\n1. Sign into the [Firebase console](//console.firebase.google.com/) with the account that gives you access to the existing Google Cloud project.\n2. Click the button to create a new Firebase project.\n3. At the bottom of the page, click **Add Firebase to Google Cloud project**.\n4. In the text field, start entering the **project name** of the existing project, and then select the project from the displayed list.\n5. Click **Open project**.\n6. If prompted, review and accept the [Firebase terms](/terms), then click **Continue**.\n7. *(Optional)* Enable AI assistance in the Firebase console (called \"Gemini in Firebase\"), which can help you get started and streamline your development process.\n8. *(Optional)* Set up Google Analytics for your project,\n which enables an optimal experience using these Firebase products:\n [Firebase A/B Testing](/docs/ab-testing),\n [Cloud Messaging](/docs/cloud-messaging),\n [Crashlytics](/docs/crashlytics),\n [In-App Messaging](/docs/in-app-messaging), and\n [Remote Config](/docs/remote-config)\n (including\n [Personalization](/docs/remote-config/personalization)).\n\n Either select an existing\n [Google Analytics account](//support.google.com/analytics/answer/1009618)\n or create a new account. If you create a new account, select your\n [Analytics reporting location](/docs/projects/locations),\n then accept the data sharing settings and Google Analytics terms\n for your project.\n | You can always set up Google Analytics later in the [*Integrations* tab](//console.firebase.google.com/project/_/settings/integrations) of your settings *Project settings*.\n9. Click **Add Firebase**.\n\nFirebase\n[adds\nFirebase to your existing project](/docs/projects/use-firebase-with-existing-cloud-project#faq_what-happens-when-add-firebase).\nWhen the process completes, you'll be taken to the overview page for your\nFirebase project in the Firebase console.\n\nStep 0 (optional): Create a GitHub repository and web app\n\nIf you don't already have a web app residing in a GitHub repository, or if you'd\nrather try the flow with a sample app, start by initializing one of our samples,\nfor either Next.js or Angular: \n\n npm init @apphosting\n\nYou can run the sample app locally using `next dev` or `ng start`. To continue,\n[create a new GitHub repository](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-new-repository)\nand push the newly-initialized sample code to it.\n\nStep 1: Create an App Hosting backend\n\nAn App Hosting backend is the collection of managed resources that\nApp Hosting creates to build and run your web app.\n| A project Owner must create the *first* App Hosting backend for a project. After this initial setup, App Hosting Admins also can create and manage additional backends. For details, see [Firebase App Hosting IAM roles](/docs/projects/iam/roles-predefined-product#app-hosting).\n\n**Firebase console** : From the **Build** menu, select **App Hosting** and then\n**Get started**.\n\n**CLI:** (Version 13.15.4 or later) To create a backend, run the following\ncommand from the root of your local project directory, supplying your\n[projectID](/docs/projects/learn-more#project-id) as an argument: \n\n firebase apphosting:backends:create --project \u003cvar label=\"project ID\" translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\n\nFor both console or CLI, follow the prompts to choose a\n[region](/docs/app-hosting/about-app-hosting#locations), set up a\n[GitHub connection](/docs/app-hosting/about-app-hosting#repo-integration),\nand configure these basic deployment settings:\n\n- Set **your app's root directory** (defaults to `/`)\n\n This is usually where your `package.json` file is located.\n\n\u003c!-- --\u003e\n\n- Set the **live branch**\n\n This is the branch of your GitHub repository that gets deployed to your\n live URL. Often, it's the branch into which feature branches or development\n branches are merged.\n- Accept or decline **automatic rollouts**\n\n Automatic rollouts are enabled by default. At completion of backend creation,\n you can choose for your app to be deployed to App Hosting immediately.\n- Assign a name to your backend.\n\nStep 2: View the deployed app\n\nWhen you create a backend, Firebase gives you a no-cost subdomain where end\nusers can visit your web app. Its format\nis \u003cvar translate=\"no\"\u003ebackend-id\u003c/var\u003e`--`\u003cvar translate=\"no\"\u003eproject-id\u003c/var\u003e`.us-central1.hosted.app`.\n\nTo view your web app's URL, check the Firebase console, or run the following CLI\ncommand: \n\n firebase apphosting:backends:get --project \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e \u003cvar translate=\"no\"\u003e{BACKEND_ID}\u003c/var\u003e\n\n| **Note:** After creating your backend, it may take around five minutes for your app's URL to work.\n\nStep 3: Trigger a rollout by pushing a change\n\nOnce your backend is created and you have a live URL, you can\ntrigger the rollout of a new version of your web app whenever you push\nchanges into the live branch of your GitHub repository. To perform a\ntest of your App Hosting setup:\n\n1. In GitHub, push a change to the live branch of the web app.\n2. Open the [App Hosting tab](//console.firebase.google.com/project/_/apphosting) in the Firebase console and select **View dashboard** for your backend. The table list displays the specific commit associated with the rollout triggered by your change.\n\nNext steps\n\n- Go deeper: walk through a Firebase codelab that integrates a hosted app with Firebase Authentication and Google AI features: [Next.js](https://firebase.google.com/codelabs/firebase-nextjs) \\| [Angular](https://firebase.google.com/codelabs/firebase-web)\n- [Connect a custom domain](/docs/app-hosting/custom-domain).\n- [Configure your backend](/docs/app-hosting/configure)---set environment variables, store secret parameters, and more.\n- [Monitor rollouts, site usage, and logs](/docs/app-hosting/rollouts)."]]
