ember fastboot/don't import node_modules脚本

ember.js

Chris Nevill Trevor Johns · 技术社区 · 6 年前

我首先要指出的是,我是从这里交叉发帖的: https://github.com/ember-fastboot/ember-cli-fastboot/issues/621 到目前为止,这个问题还没有引起任何关注,所以我正在向更广泛的社区开放。

我正在尝试使ember cli slick fastboot兼容。它使用来自节点模块的slick.js,如下所示:

included: function(app) {
this._super.included(app);

app.import("node_modules/slick-carousel/slick/slick.js");

我想让树商工作,但运气不好。我在跟踪文件 https://www.ember-fastboot.com/docs/addon-author-guide#third-party-dependencies 但我怀疑它的目标是Bower而不是NPM/node_模块。

treeForVendor(defaultTree) {        
    var browserVendorLib = new Funnel('node_modules/slick-carousel/slick/slick.js');    

    browserVendorLib = map(browserVendorLib, (content) => `if (typeof FastBoot === 'undefined') { ${content} }`);

    return new mergeTrees([defaultTree, browserVendorLib]);
  },

这会导致错误:

生成错误(花椰菜持久过滤器:映射器)

enotdir:不是目录,scandir 'projectdir/tmp/broccoli_persistent_filtermapper-input_base_path-foinixjr.tmp/'

我也试过了

  treeForVendor(defaultTree) {        
    var map = require("broccoli-stew").map;
    var Funnel = require("broccoli-funnel");
    const mergeTrees = require('broccoli-merge-trees');

    let tree=new Funnel('node_modules/slick-carousel/slick/', {
      destDir: 'slick-carousel',
      files: ['slick.js']
    })

    tree = map(tree, (content) => `if (typeof FastBoot === 'undefined') { ${content} }`);


    return new mergeTrees([defaultTree, tree]);
  },

这至少建立了..但是我回到了快速引导错误

引用错误:jquery未在处定义 projectfolder/tmp/broccoli_merge_trees-output_path-8cgo0zcl.tmp/assets/node_modules/slick carousel/slick/slick.js:25:1

我已经创建了一个干净的空Ember插件项目,其中只包含import和treeforvendor函数来演示这个问题。 https://github.com/MrChriZ/ember-slicker

有几件事我错过了,也许加载项指南可以更清楚。

首先,我认为漏斗图采用的是目录路径,而不是完整的文件路径。在此基础上,路径必须是完整的文件路径。这并没有立即从FastBoot插件指南中清除。
所以看起来像这样:

const assetDir = path.join(this.project.root, 'node_modules', 'slick-carousel', 'slick');
       var browserVendorLib = new Funnel(assetDir, {
         files: ['slick.js'],
         destDir: 'slick'
       });

你不能做的是

const assetDir = path.join(this.project.root, 'node_modules', 'slick-carousel', 'slick', 'slick.js);
var browserVendorLib = new Funnel(assetDir);

这会引发:

enotdir:不是目录

我相信,因为漏斗期望的是目录路径而不是文件路径。

其次,在包含的hook gaurav中,在github上正确地指出了导入语句需要更改为指向供应商目录。

所以我的最终解决方案是:

treeForVendor(defaultTree) {        
   var map = require("broccoli-stew").map;
   var Funnel = require("broccoli-funnel");
   const mergeTrees = require('broccoli-merge-trees');

   const assetDir = path.join(this.project.root, 'node_modules', 'slick-carousel', 'slick');
   var browserVendorLib = new Funnel(assetDir, {
     files: ['slick.js'],
     destDir: 'slick'
   });    

   browserVendorLib = map(browserVendorLib, (content) => `if (typeof FastBoot === 'undefined') { ${content} }`);

   return new mergeTrees([defaultTree, browserVendorLib]);
 },
 included: function(app) {
   this._super.included(app);

   app.import('node_modules' + '/slick-carousel/slick/slick.css');
   app.import('node_modules'+ '/slick-carousel/slick/slick-theme.css');
   app.import('node_modules' + '/slick-carousel/slick/fonts/slick.ttf', { destDir: 'assets/fonts' });
   app.import('node_modules' + '/slick-carousel/slick/fonts/slick.svg', { destDir: 'assets/fonts' });
   app.import('node_modules' + '/slick-carousel/slick/fonts/slick.eot', { destDir: 'assets/fonts' });
   app.import('node_modules' + '/slick-carousel/slick/fonts/slick.woff', { destDir: 'assets/fonts' });
   app.import('node_modules' + '/slick-carousel/slick/ajax-loader.gif', { destDir: 'assets' });

   // import the above library into vendor.js that was merged with the vendor trees. In browser the library will be eval'd and run
   // In fastboot, the library will not be eval'd
   app.import('vendor/slick/slick.js');
 }
