Webpack拿着巴贝尔和把手的档案
Webpack拿着巴贝尔和把手的档案
提问于 2020-12-09 19:59:15
修改后，我对此相当陌生，而且我一直在努力解决这个问题，所以我非常感谢您的帮助。
目标：创建动态网页，使用工具栏和D3进行动态文本和可视化。
到目前为止我所取得的成果：使用存储在其中的json文件进行一些数据操作，并使用hbs和express呈现数据。创建简单的条形图，使用上一个文件中的数据。
问题：，我不知道如何完全设置webpack，这样我才能真正看到我的页面是什么样子的。如果我只是将带有D3可视化的脚本添加到需要的hbs中是没有定义的，这是我得到的，因为客户端不支持它。

|babel.config.json到目前为止，我的代码(这里可能有很多东西，因为我尝试了很多东西，而且我是匿名的，因为我有敏感的项目)。
index.js：
const express = require("express");
const fs = require("fs");
const path = require("path");
const hbs = require("hbs");
const Data = JSON.parse(
fs.readFileSync(path.resolve(__dirname, "../data/data.json")).toString()
);
//Some data manipulation
module.exports = clusters; //array to be used in the other file
const app = express();
const publicDirectoryPath = path.join(__dirname, "..");
const viewPath = path.join(__dirname, "../templates/views");
app.set("view engine", "hbs");
app.set("views", viewPath);
app.use(express.static(publicDirectoryPath));
app.get("", (req, res) => {
res.render("index", {
data1: data1,
data2:data2,
});
});visuals.js的开始
const d3 = require("d3");
var dt = require("./index.js");
const clusters = dt.clusters;webpack.config.js

您发布的错误意味着webpack被要求创建一些引用节点包(如http )的JS包。在客户端代码包中引用类似的包是行不通的，因为它不能在JS构件中打包节点模块。
确保您通过webpack捆绑的文件不需要/导入特定于节点的包。因为看起来你在创建一个特快专递应用程序，所以请将特快专递文件保存在webpack访问的文件夹之外。
