[英]Module export with default parameters
I am trying to export a module in Node.js with some functions in it.我正在尝试在 Node.js 中导出一个模块,其中包含一些功能。 One of the functions have optional parameters which include default values.
其中一个函数具有可选参数,其中包括默认值。
module.exports = {
foo = (a, b = 2, c = {y:0}) => {
// Code
},
bar = () => {
// Codes
},
}
The functions work when it is not exported.这些功能在未导出时起作用。 When moved into
module.exports
, the following error occurs:移入
module.exports
时,会出现以下错误:
SyntaxError: Invalid shorthand property initializer

I am aware the parameters can be default-ed in the code of the function.我知道参数可以在 function 的代码中进行默认设置。 Still, does default-ing parameters in brackets not work in
module.exports
?不过,括号中的默认参数在
module.exports
中不起作用吗? Any help in fixing it?任何帮助修复它? Thanks.
谢谢。
You object notation is incorrect:您的 object 表示法不正确:
Change foo = () => {}
to foo: () => {}
将
foo = () => {}
更改为foo: () => {}
module.exports = {
foo: (a, b = 2, c = {y:0}) => {
// Code
},
bar: () => {
// Codes
}
}
