开源应用更轻松的自动更新
今天，我们发布了免费、开源、托管的 更新 Web 服务 及其配套 npm 包，以便轻松实现开源 Electron 应用的自动更新。这是让应用开发者更少考虑部署，更多地关注为用户开发高质量体验的一步。
¥Today we're releasing a free, open-source, hosted updates webservice and companion npm package to enable easy automatic updates for open-source Electron apps. This is a step toward empowering app developers to think less about deployment and more about developing high-quality experiences for their users.
让生活更轻松
¥Making life easier
Electron 拥有 autoUpdater API，使应用能够使用来自远程端点的元数据来检查更新、在后台下载并自动安装。
¥Electron has an autoUpdater API that gives apps the ability to consume metadata from a remote endpoint to check for updates, download them in the background, and install them automatically.
对于许多 Electron 应用开发者来说，启用这些更新一直是部署过程中繁琐的一步，因为它需要部署和维护一个 Web 服务器来提供应用版本历史元数据。
¥Enabling these updates has been a cumbersome step in the deployment process for many Electron app developers because it requires a web server to be deployed and maintained just to serve app version history metadata.
今天，我们宣布推出一款用于自动应用更新的全新嵌入式解决方案。如果你的 Electron 应用位于公共 GitHub 仓库中，并且你使用 GitHub Releases 发布构建版本，则可以使用此服务向用户提供持续的应用更新。
¥Today we are announcing a new drop-in solution for automatic app updates. If your Electron app is in a public GitHub repository and you're using GitHub Releases to publish builds, you can use this service to deliver continuous app updates to your users.
使用新模块
¥Using the new module
为了最大限度地减少你的配置工作，我们创建了 update-electron-app，这是一个与新的 update.electronjs.org Web 服务集成的 npm 模块。
¥To minimize configuration on your part, we've created update-electron-app, an npm module which integrates with the new update.electronjs.org webservice.
安装模块：
¥Install the module:
npm install update-electron-app
可在应用的 主进程 中的任何位置调用：
¥Call it from anywhere in your app's main process:
require('update-electron-app')();
就是这样！该模块将在应用启动时检查更新，然后每十分钟检查一次。当发现更新时，它会在后台自动下载，并在更新准备就绪时显示一个对话框。
¥That's it! The module will check for updates at app startup, then every ten minutes. When an update is found it will download automatically in the background, and a dialog will be displayed when the update is ready.
迁移现有的应用
¥Migrating existing apps
已经使用 Electron autoUpdater API 的应用也可以使用此服务。为此，你可以使用 自定义 update-electron-app 模块或 直接与 update.electronjs.org 集成 模块。
¥Apps already using Electron's autoUpdater API can use this service too.
To do so, you can
customize the update-electron-app module
or
integrate directly with update.electronjs.org.
替代方案
¥Alternatives
如果你使用 electron-builder 打包应用，可以使用其内置的更新程序。详情请参阅 electron.build/auto-update。
¥If you're using electron-builder to package your app, you can use its built-in updater. For details, see electron.build/auto-update.
如果你的应用是私有的，则可能需要运行自己的更新服务器。有很多开源工具可以实现这一点，包括 Zeit 的 Hazel 和 Atlassian 的 核。请参阅 部署更新服务器 教程了解更多信息。
¥If your app is private, you may need to run your own update server. There are a number of open-source tools for this, including Zeit's Hazel and Atlassian's Nucleus. See the Deploying an Update Server tutorial for more info.
