了解如何部署 Expo 网站进行生产。
Expo Web 应用可以在本地提供服务以测试生产行为,并部署到托管服务。我们建议部署到 EAS 托管 以获得最佳功能支持。你还可以自行托管或使用第三方服务。
¥An Expo web app can be served locally for testing the production behavior, and deployed to a hosting service. We recommend deploying to EAS Hosting for the best feature support. You can also self-host or use a third-party service.
EAS Hosting 是部署 Web 应用的最佳方式,支持自定义域、SSL 等。
对于 SDK 49 及以下版本,你可能需要 发布 webpack
构建的指南。
¥For SDK 49 and below, you may need the guide for publishing webpack
builds.
¥Output targets
可以在 应用配置 中配置 web.output
目标来设置 Web 应用的导出方法:
¥The web.output
target can be configured in the app config to set the export method for the web app:
{
"expo": {
"web": {
"output": "server",
"bundler": "metro"
}
}
}
Expo Router 支持 Web 应用的三个输出目标。
¥Expo Router supports three output targets for web apps.
输出 | Expo 路由 | API 路由 | 描述 |
---|---|---|---|
single (默认) | 在输出目录中输出带有单个 index.html 的单页应用 (SPA),并且没有静态可索引的 HTML。 | ||
server | 创建客户端和服务器目录。客户端文件作为单独的 HTML 文件输出。API 路由作为单独的 JavaScript 文件,用于托管自定义 Node.js 服务器。 | ||
static | 为应用目录中的每个路由输出单独的 HTML 文件。 |
¥Create a build
创建项目的构建是发布 Web 应用的第一步。无论你是要在本地提供服务还是部署到托管服务,你都需要导出项目的所有 JavaScript 和资源。这称为静态打包包。可以通过运行以下命令导出它:
¥Creating a build of the project is the first step to publishing a web app. Whether you want to serve it locally or deploy to a hosting service, you'll need to export all JavaScript and assets of a project. This is known as a static bundle. It can be exported by running the following command:
运行通用导出命令来编译 Web 项目:
¥Run the universal export command to compile the project for web:
-
npx expo export -p web
生成的项目文件位于 dist 目录中。public 目录中的所有文件也会复制到 dist 目录中。
¥The resulting project files are located in the dist directory. Any files inside the public directory are also copied to the dist directory.
¥Serve locally
使用 npx expo serve
在本地快速测试你的网站在生产环境中的托管方式。运行以下命令来提供静态打包包:
¥Use npx expo serve
to quickly test locally how your website will be hosted in production. Run the following command to serve the static bundle:
-
npx expo serve
打开 http://localhost:8081
查看你的项目的运行情况。这仅适用于 HTTP,因此权限、相机、位置和许多其他安全功能可能无法按预期工作。
¥Open http://localhost:8081
to see your project in action. This is HTTP only, so permissions, camera, location, and many other secure features may not work as expected.
¥Hosting with EAS
当你准备好投入生产时,你可以立即使用 EAS CLI 部署你的网站。
¥When you're ready to go to production, you can instantly deploy your website with EAS CLI.
EAS Hosting 是部署 Web 应用的最佳方式,支持自定义域、SSL 等。
¥Hosting on third-party services
Netlify 是一个几乎没有任何意见的用于部署 Web 应用的平台。这与 Expo Web 应用具有最高的兼容性,因为它对框架做了很少的假设。
¥Netlify is a mostly-unopinionated platform for deploying web apps. This has the highest compatibility with Expo web apps as it makes few assumptions about the framework.
¥Manual deployment with the Netlify CDN
1
通过运行以下命令安装 Netlify CLI:
¥Install the Netlify CLI by running the following command:
-
npm install -g netlify-cli
2
为单页应用配置重定向。
¥Configure redirects for single-page applications.
如果你的应用使用 静态渲染,那么你可以跳过此步骤。
¥If your app uses static rendering, then you can skip this step.
expo.web.output: 'single'
生成一个单页应用。这意味着只有一个 dist/index.html 文件,所有请求都必须重定向到该文件。这可以在 Netlify 中通过创建 ./public/_redirects 文件并将所有请求重定向到 /index.html 来完成。
¥expo.web.output: 'single'
generates a single-page application. It means there's only one dist/index.html file to which all requests must be redirected. This can be done in Netlify by creating a ./public/_redirects file and redirecting all requests to /index.html.
/* /index.html 200
如果修改此文件,则必须使用 npx expo export -p web
重建项目才能将其安全地复制到 dist 目录中。
¥If you modify this file, you must rebuild your project with npx expo export -p web
to have it safely copied into the dist directory.
3
通过运行以下命令部署 Web 构建目录:
¥Deploy the web build directory by running the following command:
-
netlify deploy --dir dist
你将看到一个可用于在线查看项目的 URL。
¥You'll see a URL that you can use to view your project online.
¥Continuous delivery
当你推送到 git 或打开新的拉取请求时,Netlify 还可以构建和部署:
¥Netlify can also build and deploy when you push to git or open a new pull request:
选择你的 Git 托管服务并选择你的存储库。
¥Pick your Git hosting service and select your repository.
单击“构建你的网站”。
¥Click Build your site.
Vercel 具有单命令部署流程。
¥Vercel has a single-command deployment flow.
1
2
为单页应用配置重定向。
¥Configure redirects for single-page applications.
在应用的根目录创建 vercel.json 文件并添加以下配置:
¥Create a vercel.json file at the root of your app and add the following configuration:
{
"buildCommand": "expo export -p web",
"outputDirectory": "dist",
"devCommand": "expo",
"cleanUrls": true,
"framework": null,
"rewrites": [
{
"source": "/:path*",
"destination": "/"
}
]
}
如果你的应用使用 静态渲染,那么你可能需要添加额外的 动态路由配置。
¥If your app uses static rendering, then you may want to add additional dynamic route configuration.
3
部署网站。
¥Deploy the website.
-
vercel
现在,你将看到一个可用于在线查看项目的 URL。构建完成后,将该 URL 粘贴到浏览器中,你将看到已部署的应用。
¥You'll now see a URL that you can use to view your project online. Paste that URL into your browser when the build is complete, and you'll see your deployed app.
¥AWS Amplify Console
AWS Amplify 控制台 提供基于 Git 的工作流程,用于持续部署和托管全栈无服务器 Web 应用。Amplify 从存储库而不是从你的计算机部署 PWA。在本指南中,我们将使用 GitHub 存储库。在开始之前,在 GitHub 上创建一个新的存储库.
¥The AWS Amplify Console provides a Git-based workflow for continuously deploying and hosting full-stack serverless web apps. Amplify deploys your PWA from a repository instead of from your computer. In this guide, we'll use a GitHub repository. Before starting, create a new repo on GitHub.
1
将 amplify-explicit.yml 文件添加到存储库的根目录。确保你已从 .gitignore 文件中删除生成的 dist 目录并提交这些更改。
¥Add the amplify-explicit.yml file to the root of your repository. Ensure you have removed the generated dist directory from the .gitignore file and committed those changes.
2
将本地 Expo 项目推送到 GitHub 存储库。如果你还没有推送到 GitHub,请关注 将现有项目添加到 GitHub 的 GitHub 指南。
¥Push your local Expo project to a GitHub repository. If you haven't pushed to GitHub yet, follow GitHub's guide to add an existing project to GitHub.
3
登录 放大控制台 并选择现有应用或创建新应用。授予 Amplify 读取你的 GitHub 账户或拥有你的存储库的组织的权限。
¥Login to the Amplify Console and select an existing app or create a new app. Grant Amplify permission to read from your GitHub account or the organization that owns your repo.
4
添加你的存储库,选择分支,然后选择连接单一存储库?输入应用 dist 目录的路径并选择下一步。
¥Add your repo, select the branch, and select Connecting a monorepo? to enter the path to your app's dist directory and choose Next.
Amplify 控制台将检测项目中的 amplify.yml 文件。选择允许 AWS Amplify 自动部署项目根目录中托管的所有文件,然后选择下一步。
¥The Amplify Console will detect the amplify.yml file in your project. Select Allow AWS Amplify to automatically deploy all files hosted in your project root directory and choose Next.
5
检查你的设置并选择保存并部署。你的应用现在将部署到 https://branchname.xxxxxx.amplifyapp.com
URL。你现在可以访问你的 Web 应用、部署另一个分支,或在你的 Expo 移动和 Web 应用中添加统一的后端环境。
¥Review your settings and choose Save and deploy. Your app will now be deployed to a https://branchname.xxxxxx.amplifyapp.com
URL. You can now visit your web app, deploy another branch, or add a unified backend environment across your Expo mobile and web apps.
按照了解如何充分利用 Amplify Hosting 下拉列表中的步骤添加具有免费 SSL 证书的自定义域和更多信息。
¥Follow the steps in the Learn how to get the most out of Amplify Hosting drop-down to Add a custom domain with a free SSL certificate and more information.
¥Firebase hosting
Firebase 托管 是用于 Web 项目的生产级 Web 内容托管。
¥Firebase Hosting is production-grade web content hosting for web projects.
1
使用 Firebase 控制台 创建一个 Firebase 项目,并按照这些 instructions 安装 Firebase CLI。
¥Create a firebase project with the Firebase Console and install the Firebase CLI by following these instructions.
2
使用 CLI,通过运行以下命令登录你的 Firebase 账户:
¥Using the CLI, login to your Firebase account by running the command:
-
firebase login
3
然后,通过运行以下命令初始化要托管的 Firebase 项目:
¥Then, initialize your firebase project to host by running the command:
-
firebase init
这些设置将取决于你构建 Expo 网站的方式:
¥The settings will depend on how you built your Expo website:
当询问公共路径时,请确保指定 dist 目录。
¥When asked about the public path, make sure to specify the dist directory.
当提示“配置为单页应用(将所有 URL 重写为 /index.html)”时,仅当你使用 web.output: "single"
(默认)时才选择“是”。否则,选择否。
¥When prompted Configure as a single-page app (rewrite all urls to /index.html), only select Yes if you used web.output: "single"
(default). Otherwise, select No.
4
在 package.json 的现有 scripts
属性中,添加 predeploy
和 deploy
属性。每个都有以下值:
¥In the existing scripts
property of package.json, add predeploy
and deploy
properties. Each has the following values:
"scripts": {
%%placeholder-start%%... %%placeholder-end%%
"predeploy": "expo export -p web",
"deploy-hosting": "npm run predeploy && firebase deploy --only hosting",
}
5
要部署,请运行以下命令:
¥To deploy, run the following command:
-
npm run deploy-hosting
打开控制台输出中的 URL 以检查你的部署,例如:https://project-name.firebaseapp.com
。
¥Open the URL from the console output to check your deployment, for example: https://project-name.firebaseapp.com
.
如果你想更改托管标头,请在 firebase.json 中为 hosting
部分添加以下配置:
¥In case you want to change the header for hosting add the following config for hosting
section in firebase.json:
"hosting": [
{
%%placeholder-start%%... %%placeholder-end%%
"headers": [
{
"source": "/**",
"headers": [
{
"key": "Cache-Control",
"value": "no-cache, no-store, must-revalidate"
}
]
},
{
"source": "**/*.@(jpg|jpeg|gif|png|svg|webp|js|css|eot|otf|ttf|ttc|woff|woff2|font.css)",
"headers": [
{
"key": "Cache-Control",
"value": "max-age=604800"
}
]
}
],
}
]
¥GitHub Pages
GitHub 页面 允许你直接从 GitHub 存储库发布网站。
¥GitHub Pages allows you to publish a website directly from a GitHub repository.
GitHub Pages 部署需要 Expo SDK 50 或更高版本,并使用可能无法按预期工作的实验性baseUrl
功能。
1
首先在项目中初始化一个新的 git 存储库并将其配置为推送到 GitHub 存储库。如果你已经将更改与 GitHub 存储库同步,请跳过此步骤。
¥Start by initializing a new git repository in your project and configuring it to push to a GitHub repository. If you are already syncing your changes with a GitHub repository, skip this step.
在 GitHub 网站上创建一个存储库。然后,在项目的根目录中运行以下命令:
¥Create a repository on the GitHub website. Then, run the following commands in your project's root directory:
-
git init
-
git remote add origin https://github.com/username/expo-gh-pages.git
上述命令初始化一个新的 Git 存储库并将其配置为将你的源代码推送到指定的 GitHub 存储库。
¥The above commands initialize a new Git repository and configure it to push your source code to the specified GitHub repository.
2
在你的项目中将 gh-pages
包作为开发依赖安装:
¥Install the gh-pages
package as a development dependency in your project:
-
npm install --save-dev gh-pages
-
yarn add -D gh-pages
3
要部署项目,请使用 应用配置 中的 baseUrl
属性将其配置为子域。将其值设置为字符串 /repo-name
。
¥To deploy the project, configure it to a subdomain with the baseUrl
property in app config. Set its value to the string /repo-name
.
例如,如果 GitHub 存储库是 expo-gh-pages
,则以下将是 实验 baseUrl
属性 的值:
¥For example, if the GitHub repository is expo-gh-pages
, the following will be the value of the experimental baseUrl
property:
{
"expo": {
"experiments": {
"baseUrl": "/expo-gh-pages"
}
}
}
4
通过添加 predeploy
和 deploy
脚本来修改 package.json 文件中的 scripts
。每个都有自己的价值:
¥Modify the scripts
in the package.json file by adding predeploy
and deploy
scripts. Each has its own value:
"scripts": {
%%placeholder-start%%... %%placeholder-end%%
"deploy": "gh-pages --nojekyll -d dist",
"predeploy": "expo export -p web"
}
由于 Expo 在生成的文件中使用下划线,因此你需要使用 --nojekyll
标志禁用 Jekyll。
¥Since Expo uses underscores in generated files, you need to disable Jekyll with the --nojekyll
flag.
5
要生成 Web 应用的生产版本并将其部署到 GitHub Pages,请运行以下命令:
¥To generate a production build of the web app and deploy it to GitHub Pages, run the following command:
-
npm run deploy
-
yarn deploy
这会将 Web 应用的构建发布到 GitHub 存储库的 gh-pages
分支。此分支仅包含来自 dist 目录的构建工件,以及 gh-pages
生成的 .nojekyll 文件。它不包括开发源代码。
¥This publishes a build of the web app to the gh-pages
branch of your GitHub repository. This branch only contains build artifacts from the dist directory, plus the .nojekyll file generated by gh-pages
. It does not include development source code.
6
现在 Web 应用已发布到 gh-pages
分支,请配置 GitHub Pages 以从该分支为应用提供服务。
¥Now that the web app is published to the gh-pages
branch, configure GitHub Pages to serve the app from that branch.
导航到 GitHub 存储库的“设置”选项卡。
¥Navigate to the Settings tab of the GitHub repository.
向下滚动到页面部分。
¥Scroll down to Pages section.
确保将源设置为从分支部署。
¥Ensure the Source is set to Deploy from a branch.
在分支部分下,选择 gh-pages 和根目录。
¥Under Branch section, select gh-pages and the root directory.
单击“保存”。
¥Click Save.
7
发布 Web 应用并设置 GitHub Pages 配置后,GitHub 操作将部署你的网站。你可以通过导航到存储库的“操作”选项卡来监控其进度。完成后,你的 Web 应用将在 URL http://username-on-github.github.io/repo-name
上可用。
¥Once the web app is published and the GitHub Pages configuration is set, a GitHub action will deploy your website. You can monitor its progress by navigating to your repository's Actions tab. Upon completion, your web app will be available at the URL http://username-on-github.github.io/repo-name
.
对于后续部署和更新,运行 deploy
命令,GitHub 操作将自动启动以更新你的 Web 应用。
¥For subsequent deployments and updates, run the deploy
command and the GitHub action will start automatically to update your web app.
