Node.js 设置与everyauth 一起使用的环境特定配置 [英] Node.js setting up environment specific configs to be used with everyauth

问题描述

我正在使用 node.js + express.js +everyauth.js.我已将所有的everyauth 逻辑移到一个模块文件中

I am using node.js + express.js + everyauth.js. I have moved all my everyauth logic into a module file

var login = require('./lib/everyauthLogin');

在其中我使用密钥/秘密组合加载我的 oAuth 配置文件:

inside this I load my oAuth config file with the key/secret combinations:

var conf = require('./conf');
.....
twitter: {
    consumerKey: 'ABC', 
    consumerSecret: '123'
}

这些代码对于不同的环境是不同的 - 开发/登台/生产，因为回调是不同的 url.

These codes are different for different environments - development / staging / production as the callbacks are to different urls.

问题:如何在环境配置中设置这些以过滤所有模块，或者我可以将路径直接传递到模块中吗?

Question: How do I set these in the environmental config to filter through all modules or can I pass the path directly into the module?

在环境中设置:

app.configure('development', function(){
  app.set('configPath', './confLocal');
});

app.configure('production', function(){
  app.set('configPath', './confProduction');
});

var conf = require(app.get('configPath'));

传入

app.configure('production', function(){
  var login = require('./lib/everyauthLogin', {configPath: './confProduction'});
});

?希望这是有道理的

推荐答案

我的解决方案，

My solution,

使用加载应用程序

NODE_ENV=production node app.js

然后将 config.js 设置为函数而不是对象

Then setup config.js as a function rather than an object

module.exports = function(){
    switch(process.env.NODE_ENV){
        case 'development':
            return {dev setting};

        case 'production':
            return {prod settings};

        default:
            return {error or other settings};
    }
};

然后根据 Jans 解决方案加载文件并创建一个新实例，如果需要，我们可以传入一个值，在这种情况下 process.env.NODE_ENV 是全局的，因此不需要.

Then as per Jans solution load the file and create a new instance which we could pass in a value if needed, in this case process.env.NODE_ENV is global so not needed.

var Config = require('./conf'),
    conf = new Config();

然后我们可以像以前一样访问配置对象属性

Then we can access the config object properties exactly as before

conf.twitter.consumerKey
