Node.js 风格指南

大部分的内容来源于 Airbnb styleguide

并且也参考其他一些资料:

@RisingStack's Node.js styleguide
@caolan's Node.js styleguide
@felixge's Node.js styleguide

类型

原始类型: 当你访问一个原始数据类型时，你直接操作的是它的值
- string
- number
- boolean
- null
- undefined
```
var foo = 1;
var bar = foo;

bar = 9;

console.log(foo, bar); // => 1, 9
```

复杂情况: 当你访问的是一个复杂类型时，你操作的是它的引用

object
array
function

var foo = [1, 2];
var bar = foo;

bar[0] = 9;

console.log(foo[0], bar[0]); // => 9, 9

对象

在对象创建时使用字面量语法

// bad
var item = new Object();

// good
var item = {};

使用可读的别名，避免使用保留字

// bad
var superman = {
  class: 'alien'
};

// bad
var superman = {
  klass: 'alien'
};

// good
var superman = {
  type: 'alien'
};

数组

使用字面量语法创建数组

// bad
var items = new Array();

// good
var items = [];

当你不知道数组的长度时使用Array#push.

var someStack = [];


// bad
someStack[someStack.length] = 'abracadabra';

// good
someStack.push('abracadabra');

当你需要复制数据时使用Array#slice. jsPerf

var len = items.length;
var itemsCopy = [];
var i;

// bad
for (i = 0; i < len; i++) {
  itemsCopy[i] = items[i];
}

// good
itemsCopy = items.slice();

将一个类数组对象转为数组，使用Array#slice.

function trigger() {
  var args = Array.prototype.slice.call(arguments);
  ...
}

字符串

使用单引号 '' 表示字符串

// bad
var name = "Bob Parr";

// good
var name = 'Bob Parr';

// bad
var fullName = "Bob " + this.lastName;

// good
var fullName = 'Bob ' + this.lastName;

长于80个字符的字符串应该被写成多行（使用字符串拼接或ES6的模板字符串）

注意：如果过度使用，长字符串拼接会影响性能. jsPerf & Discussion

// bad
var errorMessage = 'This is a super long error that was thrown because of Batman. When you stop to think about how Batman had anything to do with this, you would get nowhere fast.';

// bad
var errorMessage = 'This is a super long error that was thrown because \
of Batman. When you stop to think about how Batman had anything to do \
with this, you would get nowhere \
fast.';

// good
var errorMessage = 'This is a super long error that was thrown because ' +
  'of Batman. When you stop to think about how Batman had anything to do ' +
  'with this, you would get nowhere fast.';
  
// good
var errorMessage = `
  hello
  world
  this
  is
`;

当使用程序来生成字符串时，使用Array#join，而不是字符串拼接.

var items;
var messages;
var length;
var i;

messages = [{
  state: 'success',
  message: 'This one worked.'
}, {
  state: 'success',
  message: 'This one worked as well.'
}, {
  state: 'error',
  message: 'This one did not work.'
}];

length = messages.length;

// bad
function inbox(messages) {
  items = '<ul>';

  for (i = 0; i < length; i++) {
    items += '<li>' + messages[i].message + '</li>';
  }

  return items + '</ul>';
}

// good
function inbox(messages) {
  items = [];

  for (i = 0; i < length; i++) {
    items[i] = messages[i].message;
  }

  return '<ul><li>' + items.join('</li><li>') + '</li></ul>';
}

函数

函数表达式:

// anonymous function expression
var anonymous = function() {
  return true;
};

// named function expression
var named = function named() {
  return true;
};

// immediately-invoked function expression (IIFE)
(function() {
  console.log('Welcome to the Internet. Please follow me.');
})();

永远不要再一个非函数语句块内使用函数声明(if, while, 等). 将函数赋值给一个变量.

// bad
if (currentUser) {
  function test() {
    console.log('Nope.');
  }
}

// good
var test;
if (currentUser) {
  test = function test() {
    console.log('Yup.');
  };
}

永远不要将你的参数命名为 arguments, 这会与函数范围内的 arguments 对象冲突.

// bad
function nope(name, options, arguments) {
  // ...stuff...
}

// good
function yup(name, options, args) {
  // ...stuff...
}

属性

当访问属性时请使用.操作符.

var luke = {
  jedi: true,
  age: 28
};

// bad
var isJedi = luke['jedi'];

// good
var isJedi = luke.jedi;

当你要用变量访问属性时，请使用 [] .

var luke = {
  jedi: true,
  age: 28
};

function getProp(prop) {
  return luke[prop];
}

var isJedi = getProp('jedi');

⬆ back to top

变量

始终使用 var 来声明变量. 否则会创建全局变量，污染全局命名空间.

// bad
superPower = new SuperPower();

// good
var superPower = new SuperPower();

声明变量时使用一个新行, 并且每一行都使用 var 来声明.

// bad
 var items = getItems(),
      goSportsTeam = true,
      dragonball = 'z';

// good
 var items = getItems();
 var goSportsTeam = true;
 var dragonball = 'z';

最后声明未赋值的便利. 后面如果你要使用前面的变量进行赋值时会显得很便利.

// bad
var i;
var items = getItems();
var dragonball;
var goSportsTeam = true;
var len;

// good
var items = getItems();
var goSportsTeam = true;
var dragonball;
var length;
var i;

避免冗余的变量声明, 可已使用 Object 对象来构建命名空间.

// bad
var kaleidoscopeName = '..';
var kaleidoscopeLens = [];
var kaleidoscopeColors = [];

// good
var kaleidoscope = {
  name: '..',
  lens: [],
  colors: []
};

在变量作用范围的最顶端声明变量. 这可以帮你避免赋值提升的问题.

// bad
function() {
  test();
  console.log('doing stuff..');

  //..other stuff..

  var name = getName();

  if (name === 'test') {
    return false;
  }

  return name;
}

// good
function() {
  var name = getName();

  test();
  console.log('doing stuff..');

  //..other stuff..

  if (name === 'test') {
    return false;
  }

  return name;
}

// bad
function() {
  var name = getName();

  if (!arguments.length) {
    return false;
  }

  return true;
}

// good
function() {
  if (!arguments.length) {
    return false;
  }

  var name = getName();

  return true;
}

Requires

使用如下顺序来组织node代码中的require语句:

core modules
npm modules
others

// bad
var Car = require('./models/Car');
var async = require('async');
var http = require('http');

// good
var http = require('http');
var fs = require('fs');

var async = require('async');
var mongoose = require('mongoose');

var Car = require('./models/Car');

当你引入模块时，不要加 .js 后缀

  // bad
  var Batmobil = require('./models/Car.js');

  // good
  var Batmobil = require('./models/Car');

⬆ back to top

回调函数

在回调函数中要始终检测错误

//bad
database.get('pokemons', function(err, pokemons) {
  console.log(pokemons);
});

//good
database.get('drabonballs', function(err, drabonballs) {
  if (err) {
    // handle the error somehow, maybe return with a callback
    return console.log(err);
  }
  console.log(drabonballs);
});

遇到错误时从回调中返回

//bad
database.get('drabonballs', function(err, drabonballs) {
  if (err) {
    // if not return here
    console.log(err);
  }
  // this line will be executed as well
  console.log(drabonballs);
});

//good
database.get('drabonballs', function(err, drabonballs) {
  if (err) {
    // handle the error somehow, maybe return with a callback
    return console.log(err);
  }
  console.log(drabonballs);
});

当你要开发接口给外部时，在你的回调函数中使用描述性的参数。它能够让你的代码更可读。

// bad
function getAnimals(done) {
  Animal.get(done);
}

// good
function getAnimals(done) {
  Animal.get(function(err, animals) {
    if(err) {
      return done(err);
    }

    return done(null, {
      dogs: animals.dogs,
      cats: animals.cats
    })
  });
}

⬆ back to top

Try catch

只能在同步函数中使用throw

Try-catch 语句块不能被用在异步代码块中。

//bad
function readPackageJson (callback) {
  fs.readFile('package.json', function(err, file) {
    if (err) {
      throw err;
    }
    ...
  });
}
//good
function readPackageJson (callback) {
  fs.readFile('package.json', function(err, file) {
    if (err) {
      return  callback(err);
    }
    ...
  });
}

在同步调用中捕获错误，JSON.parse()应该使用try-catch语句块

//bad
var data = JSON.parse(jsonAsAString);

//good
var data;
try {
  data = JSON.parse(jsonAsAString);
} catch (e) {
  //handle error - hopefully not with a console.log ;)
  console.log(e);
}

⬆ back to top

提升

变量声明会被提升到作用域的顶端，而赋值操作则不会。

// 先看个简单的例子，显然它会抛出错误
function example() {
  console.log(notDefined); // => throws a ReferenceError
}

// 我们先使用了一个变量，而后再声明并初始化这个变量
// 输出结果没有报错，而是 `undefined`，意思是未被初始化
function example() {
  console.log(declaredButNotAssigned); // => undefined
  var declaredButNotAssigned = true;
}

// 变量声明部分会被提升，赋值部分仍保持不变
// 上面的代码等同于
function example() {
  var declaredButNotAssigned;
  console.log(declaredButNotAssigned); // => undefined
  declaredButNotAssigned = true;
}

匿名函数表达式会提升它们的变量名，但是函数赋值部门不会被提升

function example() {
  console.log(anonymous); // => undefined

  anonymous(); // => TypeError anonymous is not a function

  var anonymous = function() {
    console.log('anonymous function expression');
  };
}

命名函数表达式会提升它们的变量名，但函数名或函数体不会被提升。

function example() {
  console.log(named); // => undefined

  named(); // => TypeError named is not a function

  superPower(); // => ReferenceError superPower is not defined

  var named = function superPower() {
    console.log('Flying');
  };
}

// the same is true when the function name
// is the same as the variable name.
function example() {
  console.log(named); // => undefined

  named(); // => TypeError named is not a function

  var named = function named() {
    console.log('named');
  }
}

函数声明会被整体提升到作用域顶端

function example() {
  superPower(); // => Flying

  function superPower() {
    console.log('Flying');
  }
}

条件表达式 & 相等性

使用 === 和 !== 来代替 == 和 !=.
条件表达式会被使用ToBoolean方法进行强制类型转换。并且服从如下规则：
- Objects 被转换为 true
- Undefined 被转换为 false
- Null 被转换为 false
- Booleans 被转换为 实际的boolean值
- Numbers 被转换为 false 如果是 +0, -0, or NaN, 其他都为 true
- Strings 被转换为 false 如果是空字符串 '', 其他都为 true
```
if ([0]) {
  // true
  // 数组是对象，对象始终被转换为 `true`
}
```

使用缩减版.

// bad
if (name !== '') {
  // ...stuff...
}

// good
if (name) {
  // ...stuff...
}

// bad
if (collection.length > 0) {
  // ...stuff...
}

// good
if (collection.length) {
  // ...stuff...
}

代码块

所有的多行代码块都要使用大括号，并且不要写在一行

// bad
if (test)
  return false;

// bad
if (test) return false;

// good
if (test) {
  return false;
}

// bad
function() { return false; }

// good
function() {
  return false;
}

⬆ back to top

注释

使用 /** ... */ 进行多行注释. 请在你们加入注释说明，指明参数和返回值的类型

// bad
// make() returns a new element
// based on the passed in tag name
//
// @param <String> tag
// @return <Element> element
function make(tag) {

  // ...stuff...

  return element;
}

// good
/**
 * make() returns a new element
 * based on the passed in tag name
 *
 * @param <String> tag
 * @return <Element> element
 */
function make(tag) {

  // ...stuff...

  return element;
}

使用 // 进行单行注释. 请用一个新行来添加注释。并在注释行前增加一个空行。

// bad
var active = true;  // is current tab

// good
// is current tab
var active = true;

// bad
function getType() {
  console.log('fetching type...');
  // set the default type to 'no type'
  var type = this._type || 'no type';

  return type;
}

// good
function getType() {
  console.log('fetching type...');

  // set the default type to 'no type'
  var type = this._type || 'no type';

  return type;
}

如果是为了指明一个错误，请在你的注释前加上FIXME或TODO前缀来帮助其他开发者快速的了解你的注释意图。其中FIXME可以表示这个问题需要解决，或者TODO来表示需要被实现的功能块。

使用 // FIXME: 来注解一个问题。

function Calculator() {

  // FIXME: shouldn't use a global here
  total = 0;

  return this;
}

使用 // TODO: 来注解一个需要被实现（完成）的任务。

function Calculator() {

  // TODO: total should be configurable by an options param
  this.total = 0;

  return this;
}

## 空格

- 推荐使用2个空格作为缩进

  ```javascript
  // bad
  function() {
  ∙∙∙∙var name;
  }

  // bad
  function() {
  ∙var name;
  }

  // good
  function() {
  ∙∙var name;
  }
  ```

- 在所有起始的大括号前加一个空格

  ```javascript
  // bad
  function test(){
    console.log('test');
  }

  // good
  function test() {
    console.log('test');
  }

  // bad
  dog.set('attr',{
    age: '1 year',
    breed: 'Bernese Mountain Dog'
  });

  // good
  dog.set('attr', {
    age: '1 year',
    breed: 'Bernese Mountain Dog'
  });
  ```

- 在操作符见使用一个空格

  ```javascript
  // bad
  var x=y+5;

  // good
  var x = y + 5;
  ```

- 文件结束后增加一个空行

  ```javascript
  // bad
  (function(global) {
    // ...stuff...
  })(this);
  ```

  ```javascript
  // bad
  (function(global) {
    // ...stuff...
  })(this);↵
  ↵
  ```

  ```javascript
  // good
  (function(global) {
    // ...stuff...
  })(this);↵
  ```

- 对链接起来的方法使用缩进成多行的形式

  ```javascript
  // bad
  $('#items').find('.selected').highlight().end().find('.open').updateCount();

  // good
  $('#items')
    .find('.selected')
      .highlight()
      .end()
    .find('.open')
      .updateCount();

  // bad
  var leds = stage.selectAll('.led').data(data).enter().append('svg:svg').class('led', true)
      .attr('width',  (radius + margin) * 2).append('svg:g')
      .attr('transform', 'translate(' + (radius + margin) + ',' + (radius + margin) + ')')
      .call(tron.led);

  // good
  var leds = stage.selectAll('.led')
      .data(data)
    .enter().append('svg:svg')
      .class('led', true)
      .attr('width',  (radius + margin) * 2)
    .append('svg:g')
      .attr('transform', 'translate(' + (radius + margin) + ',' + (radius + margin) + ')')
      .call(tron.led);
  ```

**[⬆ back to top](#table-of-contents)**

## 逗号

- 推荐的做法是逗号在每一行的末尾

  ```javascript
  // bad
  var hero = {
      firstName: 'Bob'
    , lastName: 'Parr'
    , heroName: 'Mr. Incredible'
    , superPower: 'strength'
  };

  // good
  var hero = {
    firstName: 'Bob',
    lastName: 'Parr',
    heroName: 'Mr. Incredible',
    superPower: 'strength'
  };
  ```

- Additional trailing comma: **Nope.** This can cause problems with IE6/7 and IE9 if it's in quirksmode. Also, in some implementations of ES3 would add length to an array if it had an additional trailing comma. This was clarified in ES5 ([source](http://es5.github.io/#D)):

> Edition 5 clarifies the fact that a trailing comma at the end of an ArrayInitialiser does not add to the length of the array. This is not a semantic change from Edition 3 but some implementations may have previously misinterpreted this.

  ```javascript
  // bad
  var hero = {
    firstName: 'Kevin',
    lastName: 'Flynn',
  };

  var heroes = [
    'Batman',
    'Superman',
  ];

  // good
  var hero = {
    firstName: 'Kevin',
    lastName: 'Flynn'
  };

  var heroes = [
    'Batman',
    'Superman'
  ];
  ```

**[⬆ back to top](#table-of-contents)**


## 分号作为语句块的结束

- **Yup.**

  ```javascript
  // bad
  (function() {
    var name = 'Skywalker'
    return name
  })()

  // good
  (function() {
    var name = 'Skywalker';
    return name;
  })();

  // good
  ;(function() {
    var name = 'Skywalker';
    return name;
  })();
  ```

**[⬆ back to top](#table-of-contents)**


## 类型转换 & 强制类型转换

- 在声明语句的最前端执行强制类型转换.
- Strings:

  ```javascript
  //  => this.reviewScore = 9;

  // bad
  var totalScore = this.reviewScore + '';

  // good
  var totalScore = '' + this.reviewScore;

  // bad
  var totalScore = '' + this.reviewScore + ' total score';

  // good
  var totalScore = this.reviewScore + ' total score';
  ```

- 使用 `parseInt` 来进行整数的类型转换，并且始终提供一个基数.

  ```javascript
  var inputValue = '4';

  // bad
  var val = new Number(inputValue);

  // bad
  var val = +inputValue;

  // bad
  var val = inputValue >> 0;

  // bad
  var val = parseInt(inputValue);

  // good
  var val = Number(inputValue);

  // good
  var val = parseInt(inputValue, 10);
  ```

- If for whatever reason you are doing something wild and `parseInt` is your bottleneck and need to use Bitshift for [performance reasons](http://jsperf.com/coercion-vs-casting/3), leave a comment explaining why and what you're doing.

  ```javascript
  // good
  /**
   * parseInt was the reason my code was slow.
   * Bitshifting the String to coerce it to a
   * Number made it a lot faster.
   */
  var val = inputValue >> 0;
  ```

- **Note:** Be careful when using bitshift operations. Numbers are represented as [64-bit values](http://es5.github.io/#x4.3.19), but Bitshift operations always return a 32-bit integer ([source](http://es5.github.io/#x11.7)). Bitshift can lead to unexpected behavior for integer values larger than 32 bits. [Discussion](https://github.com/airbnb/javascript/issues/109). Largest signed 32-bit Int is 2,147,483,647:

  ```javascript
  2147483647 >> 0 //=> 2147483647
  2147483648 >> 0 //=> -2147483648
  2147483649 >> 0 //=> -2147483647
  ```

- Booleans:

  ```javascript
  var age = 0;

  // bad
  var hasAge = new Boolean(age);

  // good
  var hasAge = Boolean(age);

  // good
  var hasAge = !!age;
  ```

**[⬆ back to top](#table-of-contents)**


## 命名约定

- 避免使用当个字符命名，使用描述性的名字：

  ```javascript
  // bad
  function q() {
    // ...stuff...
  }

  // good
  function query() {
    // ..stuff..
  }
  ```

- 对于对象、函数、和实例采用小驼峰（camelCase）命名法

  ```javascript
  // bad
  var OBJEcttsssss = {};
  var this_is_my_object = {};
  function c() {}
  var u = new user({
    name: 'Bob Parr'
  });

  // good
  var thisIsMyObject = {};
  function thisIsMyFunction() {}
  var user = new User({
    name: 'Bob Parr'
  });
  ```

- 当命名类或构造函数时使用大驼峰或Pascal命名法（PascalCase）

  ```javascript
  // bad
  function user(options) {
    this.name = options.name;
  }

  var bad = new user({
    name: 'nope'
  });

  // good
  function User(options) {
    this.name = options.name;
  }

  var good = new User({
    name: 'yup'
  });
  ```

- 在私有属性前加上一个 `_` 前缀

  ```javascript
  // bad
  this.__firstName__ = 'Panda';
  this.firstName_ = 'Panda';

  // good
  this._firstName = 'Panda';
  ```

- 当你要保存 `this` 值时，可以将其命名为 `_this`.

  ```javascript
  // bad
  function() {
    var self = this;
    return function() {
      console.log(self);
    };
  }

  // bad
  function() {
    var that = this;
    return function() {
      console.log(that);
    };
  }

  // good
  function() {
    var _this = this;
    return function() {
      console.log(_this);
    };
  }
  ```

- 命名你的函数。这将有助于堆栈跟踪。

  ```javascript
  // bad
  var log = function(msg) {
    console.log(msg);
  };

  // good
  var log = function log(msg) {
    console.log(msg);
  };
  ```

**[⬆ back to top](#table-of-contents)**


## 访问器

- 属性访问器并不是必须的。
- 如果你确实需要，请命名为 getVal() 和 setVal('hello') 的形式

  ```javascript
  // bad
  dragon.age();

  // good
  dragon.getAge();

  // bad
  dragon.age(25);

  // good
  dragon.setAge(25);
  ```

- 如果属性是一个布尔值，请使用 isVal() 或 hasVal()

  ```javascript
  // bad
  if (!dragon.age()) {
    return false;
  }

  // good
  if (!dragon.hasAge()) {
    return false;
  }
  ```

- 你也可以创建 get() 和 set() 函数, 但一定要保持一致.

  ```javascript
  function Jedi(options) {
    options || (options = {});
    var lightsaber = options.lightsaber || 'blue';
    this.set('lightsaber', lightsaber);
  }

  Jedi.prototype.set = function(key, val) {
    this[key] = val;
  };

  Jedi.prototype.get = function(key) {
    return this[key];
  };
  ```

**[⬆ back to top](#table-of-contents)**

## 构造函数

- 在原型链上增加属性，而不是覆写原型链。

  ```javascript
  function Jedi() {
    console.log('new jedi');
  }

  // bad
  Jedi.prototype = {
    fight: function fight() {
      console.log('fighting');
    },

    block: function block() {
      console.log('blocking');
    }
  };

  // good
  Jedi.prototype.fight = function fight() {
    console.log('fighting');
  };

  Jedi.prototype.block = function block() {
    console.log('blocking');
  };
  ```

- 你可以在方法中返回 `this` 从而来构建可链接的方法。

  ```javascript
  // bad
  Jedi.prototype.jump = function() {
    this.jumping = true;
    return true;
  };

  Jedi.prototype.setHeight = function(height) {
    this.height = height;
  };

  var luke = new Jedi();
  luke.jump(); // => true
  luke.setHeight(20) // => undefined

  // good
  Jedi.prototype.jump = function() {
    this.jumping = true;
    return this;
  };

  Jedi.prototype.setHeight = function(height) {
    this.height = height;
    return this;
  };

  var luke = new Jedi();

  luke.jump()
    .setHeight(20);
  ```


- 你可以创建一个自定义的`toString()`方法，但是你要确保它能正常工作并且没有其他副作用。

  ```javascript
  function Jedi(options) {
    options || (options = {});
