从 webpack 构建中排除 var 和 json 文件

Question

I'm trying to exclude but retain external reference to a few JSON files from a webpack build.

I've modified the webpack.config.js to include:

externals: {
        "../package.json": "package_json",
        "./font.json": "font"  
},

This solved some previous errors, but now it seems that the 'font' var is being considered undefined.

Uncaught ReferenceError: font is not defined

The error is referring to this line in the build, where webpack has exported the 'font' var as a module.export:

/!***********************!
!*** external "font" *!
********************/
/**/ function(module, exports) {

module.exports = font;

When comparing the original code to the webpack build, webpack converted this:

var font = require('./font.json'),
    Theme = require('./theme'),
    style = require('./utils').style;

to this:

'use strict';

var font = __webpack_require__(/*! ./font.json */ 334),
    Theme = __webpack_require__(/*! ./theme */ 324),
    style = __webpack_require__(/*! ./utils */ 326).style;

Which seems to leave 'font' undefined? How is webpack handling this var value here?

Webpack is somewhat new to me. Any insights into how to resolve this?

我用 json-loader 找到了解决方案：npmjs.com/package/json-loader
