webpack中的当前文件路径

Question

有没有办法接收当前的文件路径,比如requirejs？

define(['module'], function (module) {
    console.log(module.uri)
});

Answer 1

是的,有一个:__filename.

但默认情况下,webpack不会泄漏路径信息,您需要设置配置标志以获取真实文件名而不是mock("/index.js").

// /home/project/webpack.config.js
module.exports = {
  context: __dirname,
  node: {
    __filename: true
  }
}

您可以使用__filename获取相对于context选项的当前文件名:

// in /home/project/dir/file.js
console.log(__filename);
// => logs "dir/file.js"

文件名仅嵌入到使用的模块中__filename.因此,您不必担心路径会从其他模块中泄露出来.

Answer 2

To get the filename an the dir name I added this to the web pack config

node : {
   __filename: true,
   __dirname: true,
},

setting the context to __dirname messed up my web pack config since I have my webpackconfig not placed in root but the paths are setup that way

尝试webpack.DefinePlugin使用webpack.DefinePlugin.runtimeValue. 它给出实数常量，可以在 ES6import和require().

网络包配置：

new webpack.DefinePlugin({
    __NAME: webpack.DefinePlugin.runtimeValue(
        v => {
            const res = v.module.rawRequest.substr(2)
            return JSON.stringify(res); // Strings need to be wrapped in quotes
        }, []
    )
})

// OR

new webpack.DefinePlugin(
    __NAME: webpack.DefinePlugin.runtimeValue(
        v => {
            const res = v.module.rawRequest.substr(2)
            return `'${res.substr(0, res.lastIndexOf('.'))}'`
        }, []
    )
})

源文件：

// require "<filename>.html" from "<filename>.js"
const html = require(`./${__NAME}.html`)
