Apple Silicon 芯片支持

· 阅读时间：约 5 分钟

随着苹果芯片将于今年晚些时候发布，您如何让Electron应用程序在新硬件上运行？

随着Electron 11.0.0-beta.1的发布，Electron团队现在正在编写在苹果计划于今年晚些时候发货的新苹果芯片上运行的Electron版本。 你可以通过npm install electron@beta或从官网来下载最新的Beta版本。

它是如何工作的？​

从Electron 11开始，我们将为Intel Mac和Apple Silicon Mac发布不同的Electron版本。 在这个变化之前，我们已经发布了两个版本， darwin-x64 和 mas-x64，后者是用于Mac App Store 兼容性的使用。 我们现在已发布另外两个版本 darwin-arm64 和 mas-arm64，为上述版本的 Apple Silicon 版本。

我需要做什么？​

您将需要发布两个版本的应用：一个版本用于 x64(Intel Mac)，另一个版本用于arm64(Apple Silicon)。 好消息是 electron-packager, electron-rebuild 和 electron-forge 已经为 arm64 架构做好了支持。 只要您正在运行这些软件包的最新版本，您的应用就应该在将目标架构更新到 arm64 后正常工作。

将来， 我们将发布一个软件包，允许您将您的 arm64 和 x64 应用“合并”到一个单一的通用二进制软件包， 但值得注意的是，这个二进制文件可能会 非常巨大 并且可能不适合给用户发布。

更新：此软件包现在可在 @electron/universal 上使用。 您可以使用它将两个以打包的 x64 和 arm64 应用程序合并为一个二进制程序。

潜在问题​

原生模块​

当您正在针对一个新的架构时，您需要更新几个依赖关系，这可能会导致构建问题。 下面包含某些依赖关系的最低版本以供您参考。

依赖项版本要求
Xcode>=12.2
node-gyp>=7.1
electron-rebuild>=1.12
electron-packager>=15.1

由于这些依赖版本要求，您可能不得不修复/更新某些原生模块。 值得注意的是，Xcode 升级将引入新版本的 macOS SDK。 这可能会导致您的原生模块构建失败。

如何测试它​

目前，Apple Silicon 应用程序只在 Apple Silicon 硬件上运行，在撰写这篇博文时暂没有商业用途。 如果您有一个开发者过渡套件，您可以在那里测试您的应用程序。 否则，您将不得不等待Apple Silicon硬件的生产发布，以测试您的应用是否正常。

Rosetta 2怎么样？​

Rosetta 2 是苹果最近一次对他们的 Rosetta 技术的迭代。 允许您在新的 arm64 Apple Silicon 硬件上运行 x64 Intel 应用。 虽然我们相信x64 Electron应用程序将在Rosetta 2下运行，但有一些重要的事情需要注意（以及您应该发布原生arm64二进制文件的原因）。

  • 您的应用的性能将明显下降。 Electron / V8 为 JavaScript 使用 JIT 编译，因为 Rosetta 工作的原理。 您实际上将运行两次JIT (一次在 V8 中，一次在 Rosetta)。
  • 您失去了如内存页面大小的增加这样的 Apple Silicon 新技术的好处。
  • 我们是否提到性能将显著 降级？

Community Discord Server and Hacktoberfest

Hacktoberfest and Discord banner

Electron Community Discord Launch

Electron’s Outreach Working Group is excited to announce the launch of our official community Discord server!

Why a new Discord server?​

In its early days as the backbone of the Atom text editor, community discussion on the Electron framework occurred in a single channel in Atom’s Slack workspace. As time passed and the two projects were increasingly decoupled, the relevance of the Atom workspace to the Electron project decreased, and maintainer participation in the Slack channel declined in the same manner.

Up until now, we had still been redirecting our broader community to the Atom Slack workspace, even though we’ve had many reports from folks who have had trouble receiving invitations, and few of our core maintainers were frequenting the channel.

We’re setting up this shiny new server to be a central discussion hub for the community where you can get the latest news on all things Electron.

Get in here!​

So far, the server’s membership consists of a few maintainers who have been working together to set it up, but we’re so excited to chat with you all! Come ask for help, keep up to date with Electron releases, or just hang out with other developers. We’ve got a handy invite for you that’ll give you access to the server!

Hacktoberfest 2020

作为一个大型和长期运行的开源项目，Electron如果没有其社区的所有 贡献就不会像现在这样成功。 从提交代码到错误报告到文档更改，还有更多。 That’s why we believe in the importance of participating in Hacktoberfest to usher in a wider community of developers of all skill levels into the project.

Odds and ends​

This year, we don’t have a wider project to give you all to work on, but we’d like to focus on opportunities to contribute across the Electron JavaScript ecosystem.

Look out for issues tagged hacktoberfest across our various repositories, including the main electron/electron repository, the electron/electronjs.org website, electron/fiddle, and electron-userland/electron-forge!

P.S. If you're feeling particularly adventurous, we also have a backlog of issues marked with help wanted tags if you're looking for more of a challenge.

Stuck? Come chat with us!​

Moreover, it’s also no coincidence that the grand opening of our Discord server coincides with the largest celebration of open-source software of the year. Check out the #hacktoberfest channel to ask for help on your Hacktoberfest PR. In case you missed it, here's the invite link again!

Change the default of contextIsolation from false to true (Starting in Electron 10)​

Without contextIsolation, any code running in a renderer process can quite easily reach into Electron internals or an app's preload script. That code can then perform privileged actions that Electron wants to keep restricted.

Changing this default improves the default security of Electron apps, so that apps will need to deliberately opt in to the insecure behaviour. Electron will depreciate the current default of contextIsolation in Electron 10.0, and change to the new default (true) in Electron 12.0.

For more information on contextIsolation, how to enable it easily and it's security benefits please see our dedicated Context Isolation Document.

终止对 5.x.y 的支持​

Electron 5.x.y has reached end-of-support as per the project's support policy. 我们鼓励开发者将应用程序升级到更新的 Electron 版本。

应用反馈项目​

We continue to use our App Feedback Program for testing. Projects who participate in this program test Electron betas on their apps; and in return, the new bugs they find are prioritized for the stable release. If you'd like to participate or learn more, check out our blog post about the program.

接下来​

在短期内，您可以期待团队继续专注于跟上构成 Electron 的主要组件的开发，包括 Chromium、Node 和 V8。 尽管我们谨慎地避免对发布日期做出承诺，但我们的计划是大约每季度发布一次 Electron 的新主要版本以及这些组件的新版本。 暂定 9.0.0 时间表 展示了 Electron 9 开发生命周期中的关键日期。 Also, see our versioning document for more detailed information about versioning in Electron.

For information on planned breaking changes in upcoming versions of Electron, see our Planned Breaking Changes doc.
