流星 v0.9.3.1 包中不能使用模板答案

【问题标题】：Can not use template in package for meteor v0.9.3.1流星 v0.9.3.1 包中不能使用模板

【问题描述】：

最近在研究meteor js框架，想为meteor写一个包，但是在尝试一个包的时候，模板有问题

在我的 package.js 中

   api.use([
    'templating',
    "coffeescript",
  ], "client");

  api.addFiles([
    'client/breadcrumb.coffee',
    'client/helpers.coffee',
    'client/views/breadcrumb/crumb.html'
  ], 'client');

  api.use(['coffeescript'], 'server');

  api.addFiles('server/breadcrumb.coffee', 'server');

在我的 helper.coffee 中，我使用如下 sn-p 代码：

  Template.breadcrumbs.helpers ->
  crumbs: () ->
    Breadcrumb.getCrumbs()

当我在我的应用程序中包含我的包时，它不起作用。这是错误：

【问题讨论】：

面包屑模板本身是否在 crumbs.html 中？如果是这样，您需要在添加 helpers.coffee 之前添加 html 文件。我认为您可以通过更改数组顺序来做到这一点，但我会将其分成两个 api.addFiles 调用，首先添加 crumbs.html。

标签： meteor meteor-blaze

【解决方案1】：

这只是一个加载顺序问题：Meteor 要求必须先在空格键中声明模板，然后才能引用它以在 JS 中定义它的助手。

通过在包源文件列表中声明您希望空格键 HTML 在 JS 对应项之前加载，您的错误应该会消失。

api.addFiles([
  'client/views/breadcrumb/crumb.html',
  'client/helpers.coffee',
  'client/breadcrumb.coffee'
], 'client');
