问题描述
几个小时,我无法获取Meteor包导出CoffeeScript文件中定义的变量。
For a few hours, I couldn't get my Meteor package to export variables defined in CoffeeScript files.
在 foo.coffee
中,例如,我尝试使用 @Foo = {foo :1}
, Foo = {foo:1}
, exports.Foo = {foo:1}
,等等,但是没有将工作。
In foo.coffee
, for example, I tried using @Foo = {foo: 1}
, Foo = {foo: 1}
, exports.Foo = {foo: 1}
, and so on and so forth, but nothing would work.
最后,查看Meteor ,我放置 api.export();
em> api.on_use()
调用该包并且工作。
Finally, after looking at the Meteor coffeescript test package on github, I placed the api.export();
call before the api.on_use()
call for that package and it worked.
我的套件设定如下:
foo/
.meteor/
.build/
foo.coffee
package.js
foo.coffee
foo.coffee
class FooBar
constructor: ->
Foo =
FooBar: FooBar
package.js
Package.describe({
summary: "A package that makes foo with foobar"
});
Package.on_use(function(api) {
api.use("coffeescript", "client");
api.export("Foo", "client"); // <-- Moved this to *before* the on_use declaration
api.add_files("foo.coffee", "client");
});
推荐答案
Coffeescript编译
Coffeescript compiles
@Foo =
FooBar: FooBar
$ b b
到
to
(function() {
this.Foo = {
FooBar: FooBar
};
}).call(this);
您必须先移除。
Foo
,请查看,但这不是一个好主意因为您可能需要在修改原始咖啡文件后对其进行编译。
You need to remove the this.
before Foo
, take a look at namespace, but it's not a good idea since you might need to compile it once you modify the original coffee files.
这里是我的秘诀:
名为 global_variables.js
的文件:
Foo = this.Foo;
然后将其添加到package.js中:
Then add it in your package.js:
api.add_files('xxx', 'xxx', 'global_variables.js');
然后就可以了!
