如何为 Gmail 开发 Chrome 扩展程序?

我正在考虑为 Gmail 开发 Chrome 扩展程序，我想知道当前的最佳做法是什么.

I'm thinking about developing Chrome extension for Gmail and I want to know what are the current best practices.

例如:

  • 默认为每封电子邮件附加 GPG 签名
  • 添加一个额外的按钮来做某事(我已经有了)
  • 劫持发送电子邮件并提示我完成某事的操作
  • ...
  • (只是这些例子帮助我发现什么是可能的)

有很多值得注意的扩展可以显着增强 gmail 的功能:

There are quite a few notable extensions that significantly augment gmail functionality:

  • http://www.boomeranggmail.com/
  • http://toolbox.mxhero.com/
  • http://www.wisestamp.com/
  • ...
  • (我不隶属于他们中的任何一个，我只是列举了一些)

一种选择是查看位于此处的来源~/Library/Application Support/Google/Chrome/Default

One option would be to peek into their source which is located here ~/Library/Application Support/Google/Chrome/Default

但也许有(一厢情愿)关于如何摆弄 gmail UI 和功能的良好教程/一组实践?

But maybe there is (wishful thinking) a good tutorial / set of practises on how to fiddle with gmail UI and functionality?

Gmail 扩展/gadget API - 如何向撰写工具栏添加按钮?

您必须以编程方式创建和注入按钮.这将涉及对 Gmail 源代码的大量搜索(剧透:它很难看).

You will have to create and inject the button programmatically. This will involve quite a bit of scouring the Gmail source code (spoiler: it's ugly).

您将面临的最大的长期挑战是 gmail 的布局会意外更改并破坏电子邮件发现或修改后的 UI.这两个问题要么需要一些聪明才智来解决，要么需要你熬夜想知道谷歌是否会突然破坏你的扩展.

The greatest long-term challenge you will face is that gmail's layout will change unexpectedly and break email discovery or the modified UI. Both issues either require some cleverness to solve, or will require you to stay up at night wondering whether Google will suddenly break your extension.

他们都在构建具有相似功能的复杂 API，如果 Gmail 决定显着改变他们的应用程序结构(他们不可避免地会这样做)，这些 API 都会独立中断.

They're all building out complex APIs with similar functionality, that can all break independently if Gmail decides to significantly change their app structure (which they inevitably will).

Gmail 通过闭包编译器运行其代码，从而混淆了所有内容.最重要的是，Gmail 可能是目前最复杂的 JavaScript 应用程序之一.

Gmail runs its code through the closure compiler, thereby obfuscating everything. On top of that, Gmail is probably one of the most sophisticated javascript apps out there.

我可以向你展示我到目前为止所得到的，并且知道我不是特别喜欢像 .oh.JZI.J-J5-Ji.TI-ax7 这样的选择器

I can show you what I got so far, and just so know I don't particularly like selectors like .oh.J-Z-I.J-J5-Ji.T-I-ax7

注意:http://anurag-maher.blogspot.co.uk/2012/12/developing-google-chrome-extension-for.html (他也这样做，他也使用了这样的混淆选择器)

"content_scripts": [
  {
    "matches": ["https://mail.google.com/*"],
    "css": ["mystyles.css"],
    "js": ["jquery-2.1.0.js", "myscript.js"]
  }
]

myscript.js

var icon = jQuery(".oh.J-Z-I.J-J5-Ji.T-I-ax7")
var clone = icon.clone();
clone.attr("data-tooltip", "my tooltip");
clone.on("click", function() {
    jQuery(".aDg").append("<p class='popup'>... sample content ...</p>");
});
icon.before(clone);

(重用现有的 UI 元素，让我的功能看起来很原生)

有侧边栏小工具和上下文小工具，但它们没有提供我想要实现的目标.

There are Sidebar Gadgets and Contextual Gadgets but they don not offer what I want to achieve.

Gmail Labs 是尚未完全准备好迎接黄金时段的实验性功能的试验场.它们可能随时改变、破裂或消失.

Gmail Labs is a testing ground for experimental features that aren't quite ready for primetime. They may change, break or disappear at any time.

https://groups.google.com/forum/#!forum/gmail-labs-suggest-a-labs-feature似乎开发 Gmail 实验室的能力仅限于 Google 员工.

https://groups.google.com/forum/#!forum/gmail-labs-suggest-a-labs-feature It seems like the ability to develop Gmail Labs is locked to Google employees.

是的，我真的很想知道那里有没有教程/参考资料?

(我复习了许多类似问题"，恐怕我在这里的选择有限，但如果我将您的启迪献给我，我会非常高兴)

推荐答案

看来你还没有偶然发现 gmail.js 项目.它提供了丰富的 API 允许使用 Gmail.但请注意，此项目并非由 Google 维护.这意味着 Gmail 中的任何更改都可能会破坏您的扩展程序，并且无法保证任何人都会关心更新 gmail.js 以解决这些更改.

It looks like you haven't stumbled upon the gmail.js project. It provides a rich API allowing to work with Gmail. However, please note that this project isn't maintained by Google. This means that any changes in the Gmail may break your extension and there is no guarantee that anyone will care to update gmail.js to address these changes.
