打包后的 webpack 功能使用

Question

我尝试打包 https://www.npmjs.com/package/@jscad/dxf-deserializer 库并在浏览器中使用。 来自节点的 Uage 看起来像

const deSerializer = require('@jscad/dxf-deserializer')
const rawData = fs.readFileSync('PATH/TO/file.dxf')
const jscadCode = deSerializer(rawData)

链接捆绑脚本后我现在应该如何使用它？

我试过了

let objs = deserialize(fileText,'square10x10',{output: 'csg'})

得到了

ReferenceError: deserialize is not defined

有 js 测试文件可以在 node 上正常工作

const fs = require('fs')
const path = require('path')
const test = require('ava')
const { CSG, CAG } = require('@jscad/csg')

const { nearlyEqual } = require( '../../../test/helpers/nearlyEqual' )

const { deserialize } = require( '../index' )

const samples = path.resolve('../../node_modules/@jscad/sample-files')

//
// Test suite for DXF deserialization (import)
//
test('ASCII DXF from Bourke 3D Entities to Object Conversion', t => {
  //const dxfPath = path.resolve(__dirname, '../../../../sample-files/dxf/bourke/3d-entities.dxf')
  const dxfPath = path.resolve(samples, 'dxf/bourke/3d-entities.dxf')
  t.deepEqual(true, fs.existsSync(dxfPath))

  let dxf = fs.readFileSync(dxfPath, 'UTF8')
  let objs = deserialize(dxf,'aaa',{output: 'objects'})

// expect one layer, containing 2 objects (CSG, and Line3D)
  t.true(Array.isArray(objs))
  t.is(objs.length,2)
})

尝试添加

node: {
   fs: "empty"
}

fs 模块未在浏览器中定义。 也许这就是停止创建 deserialize 的原因。试试看。
