如何在 UI 中放置我的 Meteor 应用程序版本号? [英] How can I place my Meteor apps version number in the UI?

问题描述

我有一个流星应用程序，它为不同的客户提供不同的分支.这是因为客户想要特别的东西.当然对吗?

I have a meteor application that has different branches for different clients. This is because clients want special things. Of course right?

我希望能够在 UI 某处为该客户端的应用程序部署版本放置 git 分支和标签/哈希.

I would like to be able to place the git branch and tag/hash for the deployed version of the app for that client in the UI somewhere.

问题是如何?Meteor 有没有办法获取这些信息并简单地使用它?

The question is how? Is there a way in Meteor to get this information and simply use it?

谢谢！

推荐答案

在我的生产应用中，我是这样解决这个问题的:

In my production apps I solved this issue in this way:

应用程序/.git/hooks/post.commit

App/MeteorApp/hooks/post-commit-version

App
  .git
     hooks
       post-commit (file)
  MeteorApp
    client
    server
    both
    private
      version.json
    hooks
      post-commit-version (file)

每当开发人员提交代码 .git/hooks/post-commit 时，都会执行 nodejs 脚本 存储在 App/MeteorApp/hooks/post-commit-版本.

Whenever developer commits code .git/hooks/post-commit is executed which executes nodejs script stored in App/MeteorApp/hooks/post-commit-version.

Script post-commit-version 在 App/MeteorApp/private 目录中生成 version.json 格式:

Script post-commit-version generates version.json in App/MeteorApp/private dir in format:

{
  "timestamp": "29-08-2014 23:16",
  "branch": "master",
  "commit": "3332f6dcbde57105a8dc353e5e878651cab89856"
}

存储在 private 中的所有内容都可以在生产环境中访问.

Everything stored in private is accessible to server on production.

App/MeteorApp/both/collections/Version.js:

Version = new Meteor.Collection('version');

应用程序/MeteorApp/server/startup.js

Meteor.startup(function(){
    if (Version.find().count() > 0){
        Version.remove({});
    }
    Version.insert(JSON.parse(Assets.getText("version.json")));
})

部署应用程序后，它将触发 startup 回调，并且版本将插入到集合 Version 中.

After application is deployed it will fire startup callbacks and version will be inserted to collection Version.

应用程序/MeteorApp/server/publish/version.js:

Meteor.publish('version', function () {
  return Version.find();
});

应用程序/MeteorApp/client/startup.js:

Meteor.startup(function(){
  Meteor.subscribe("version");
})

然后在模板中的某处简单地创建助手:

And then somewhere in template simply create helper:

Template.template_name.helpers({
  version:function(){
   return Version.findOne();
  }
})

在 template_name 中，您使用 {{version.commit}} {{version.branch}} {{version.timestamp}} 显示版本>.

In template_name you display version using {{version.commit}} {{version.branch}} {{version.timestamp}}.

Script post-commit-version 没有 js 扩展，因为我不想让meteor 每次都将它包含在包中或重新加载开发中的应用程序更改此文件.但是，当该文件存储在 .dir(如 App/MeteorApp/.hooks)中时，可以使用 post-commit-version.js) 作为以 . 作为第一个字符的目录不被meteor 处理.

Script post-commit-version don't have js extension, because I don't want meteor to include it in bundle or reload app in development every time I change this file. However it is possible to use post-commit-version.js when that file is stored in .dir (like App/MeteorApp/.hooks) as directories having . as first character are not processed by meteor.

另一种可能性是在服务器端加载 version.json Meteor.startup，解析 json 并附加到全局变量，如 App.version.稍后与 Meteor.method 一起使用:

Another possibility would be load version.json on server side Meteor.startup, parse json and attach to global variable like App.version. Later use it with Meteor.method:

Meteor.methods({
  getVersion:function(){
   return App.version;
  }
})

在客户端，您只需调用方法:

On client you simply call method:

Meteor.call("getVersion", function(error,version){
  if(error)  {
    throw new Error("Cannot get version");
    return;      
  }

  Session.set("version",version)
})

一些模板的助手可以使用它:

Some template's helper could use it :

Template.template_name.helpers({
  version:function(){
    return Session.get("version");
  }
})
