使用twitter bootstrap进行Browserify

Question

有很多类似的问题,包括堆栈溢出的答案,但没有一个对我有用,所以我在这里问你们.我感谢大家的时间.

我最近开始使用浏览器gulp,这非常有效.然后我尝试使用browserify作为前端使用:Backbone和Bootstrap3.

事情似乎有效,直到我尝试要求Bootstrap附带的js文件.我的chrome工具中出现错误,说明:jQuery未定义.

我试图将其填入,但我对垫片非常困惑.我正在使用jQuery 2.1.1,所以我不需要shim jQuery,但它现在存在于垫片中,因为我绝望并尝试了一切.这是我的package.json和我的main.js文件:

------------------------- main.js ----------------------

var shim = require('browserify-shim');
$ = require('jquery');
var Backbone = require('backbone');
Backbone.$ = $;
var bootstrap = require('bootstrap');

/* the following logs fine if I comment out the bootstrap require, otherwise I get 'jQuery undefined' */

console.log(Backbone);
$(function() {
    alert('jquery works');
});

如果你用npm安装它,你不应该以这种方式填充jquery.以下是我写过的项目的作品:

我还了解到使用npm进行bootstrap是一种PITA.我一直在使用bower来安装和维护某些前端组件,因为它们需要像这样进行填充.

的package.json:

{
  "name": "...",
  "version": "0.0.1",
  "description": "...",
  "repository": {
    "type": "git",
    "url": "..."
  },
  "browser": {
    "d3js": "./bower_components/d3/d3.min.js",
    "select2": "./bower_components/select2/select2.min.js",
    "nvd3js": "./bower_components/nvd3/nv.d3.min.js",
    "bootstrap": "./node_modules/bootstrap/dist/js/bootstrap.js"
  },
  "browserify": {
    "transform": [
      "browserify-shim",
      "hbsfy"
    ]
  },
  "browserify-shim": {
    "d3js": {
      "exports": "d3",
      "depends": [
        "jquery:$"
      ]
    },
    "bootstrap": {
      "depends": [
        "jquery:jQuery"
      ]
    },
    "select2": {
      "exports": null,
      "depends": [
        "jquery:$"
      ]
    },
    "nvd3js": {
      "exports": "nv",
      "depends": [
        "jquery:$",
        "d3js:d3"
      ]
    }
  },
  "devDependencies": {
    "browserify-shim": "~3.4.1",
    "browserify": "~3.36.0",
    "coffeeify": "~0.6.0",
    "connect": "~2.14.3",
    "gulp-changed": "~0.3.0",
    "gulp-imagemin": "~0.1.5",
    "gulp-notify": "~1.2.4",
    "gulp-open": "~0.2.8",
    "gulp": "~3.6.0",
    "hbsfy": "~1.3.2",
    "vinyl-source-stream": "~0.1.1",
    "gulp-less": "~1.2.3",
    "bower": "~1.3.3",
    "cssify": "~0.5.1",
    "gulp-awspublish": "0.0.16",
    "gulp-util": "~2.2.14",
    "gulp-rename": "~1.2.0",
    "gulp-s3": "git+ssh://git@github.com/nkostelnik/gulp-s3.git",
    "gulp-clean": "~0.2.4",
    "process": "~0.7.0"
  },
  "dependencies": {
    "backbone": "~1.1.2",
    "jquery": "~2.1.0",
    "lodash": "~2.4.1",
    "d3": "~3.4.8",
    "rickshaw": "~1.4.6",
    "datejs": "~1.0.0-beta",
    "moment": "~2.7.0"
  }
}

JS:

$ = jQuery = require('jquery');
var _ = require('lodash');
var Rickshaw = require('rickshaw');
var d3 = require('d3js');
var nvd3 = require('nvd3js');
var moment = require('moment');
require('datejs');
require('select2');

var bootstrap = require('bootstrap');
console.log(bootstrap)

此外 - 一个有时有用的事情是让browserify-shim输出其诊断信息.这是我的browserify.js任务的样子:

var browserify   = require('browserify');
var gulp         = require('gulp');
var handleErrors = require('../util/handleErrors');
var source       = require('vinyl-source-stream');
var process      = require('process');

process.env.BROWSERIFYSHIM_DIAGNOSTICS=1;

var hbsfy = require('hbsfy').configure({
  extensions: ['html']
});

gulp.task('browserify', ['images', 'less'], function(){
    return browserify({
      transform: ['hbsfy', 'cssify'],
            entries: ['./src/javascript/app.js'],
        })
        .bundle({debug: true})
        .on('error', handleErrors)
        .pipe(source('app.js'))
        .pipe(gulp.dest('./build/'));
});

因为我使用的是需要定义变量'$'或'jQuery'的browserify,所以存在错误.

添加窗口以使其全局解决错误.不确定这是否是正确的方法,如果没有,请告诉我.

window.$ = window.jQuery = require('jquery');
var bootstrapjs = require('bootstrap-sass');
