I am setting up a webpack, but I have a problem.
I know that libraries are automatically connected when node_modules is set in modules of resolve.
So I set up the webpack like this(the webpack file is located under the config folder in the root folder.)
const path = require('path');
const VueLoaderPlugin = require('vue-loader/lib/plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const env = process.env.NODE_ENV;
const isProd = env === "production";
module.exports = {
mode: env,
context: path.resolve(__dirname, '..'),
entry: {
app: './main.js'
},
output: {
filename: !isProd ? `js/[name].js` : 'js/[name].[contenthash:8].js',
path: path.resolve(__dirname, '../dist'),
publicPath: '/',
chunkFilename: !isProd ? `js/[name].js` : 'js/[name].[contenthash:8].js'
},
resolve: {
alias: {
'#': path.resolve(__dirname, '../src'),
vue$: 'vue/dist/vue.runtime.esm-bundler.js'
},
extensions: [
'.mjs',
'.js',
'.jsx',
'.vue',
'.json',
],
modules: [
path.resolve(__dirname, '../src'),
'node_modules',
path.resolve(__dirname, '../node_modules')
],
},
resolveLoader: {
modules: [
'node_modules',
path.resolve(__dirname, '../node_modules')
],
extensions: ['.js', '.json'],
},
module: {
noParse: /^(vue|vue-router|vuex|vuex-router-sync)$/,
rules: [
{
test: /\.vue$/,
use: ['vue-loader']
},
{
test: /\.(png|jpe?g|gif|webp)(\?.*)?$/,
use: [
{
loader: 'url-loader',
options: {
limit: 4096,
fallback: {
loader: 'file-loader',
options: {
name: 'img/[name].[hash:8].[ext]',
esModule: false
}
}
}
}
]
},
{
test: /\.(sa|sc|c)ss$/,
use: [ isProd ? {
loader: MiniCssExtractPlugin.loader
} : {
loader: 'style-loader',
}
,
{
loader: "css-loader",
options: {
sourceMap: false,
importLoaders: 2
}
},
{
loader: "sass-loader",
options: {
sourceMap: false
}
}],
},
{
enforce: 'pre',
test: /\.(vue|(j|t)sx?)$/,
exclude: [
/node_modules/,
],
use: [
{
loader: 'eslint-loader',
options: {
extensions: [
'.js',
'.jsx',
'.vue'
],
emitWarning: false,
emitError: false,
fix: true,
}
}
]
},
{
test: /\.m?jsx?$/,
use: [
{loader: 'babel-loader'}
]
}
],
},
plugins: [
new VueLoaderPlugin(),
],
}
However, despite of this setting, code cannot find node_modules.
import Vue from 'vue';
import App from "./src/App.vue";
import { router } from "./src/router/index.js";
new Vue({
router,
render: (h) => h(App),
}).$mount("#root");
this prints out error message on the dev server or at build time.
ERROR in ./main.js
Module not found: Error: Can't resolve 'vue' in '/Users/donghokim/study/wecode/vue-setting-playground/brandi-front-setting'
# ./main.js 1:0-22 5:4-7
However, if set the library path directly, it works.
import Vue from './node_modules/vue/dist/vue';
import App from "./src/App.vue";
import { router } from "./src/router/index.js";
new Vue({
router,
render: (h) => h(App),
}).$mount("#root");
How can I automatically connect node_modules?
solved.... vue$: 'vue/dist/vue.runtime.esm-bundler.js' is of vue 3. I found that vue 2 has no vue.runtime.esm-bundler.js file. After changing to vue.runtime.esm.js, webpack build works

I am using Vue with Webpack (without Vue CLI) and I ran into an issue.
I am building a Design System library, in which I would like to have async chunks so they get small.
When I import as usual the component in the index.ts of the lib
//index.ts
import RedBox from '#/components/RedBox.vue';
export { RedBox };
everything works perfectly.
But when I try to do
const RedBox = () => import('#/components/RedBox.vue');
export { RedBox };
i get

I have setup a simple webpack 5 config file with a dev server that seems to be working but when I add
<link href="/style.css" rel="stylesheet" />
to the index.html file I get no CSS loading. Currently in dev mode I am choosing to use 'style-loader' over the 'MiniCssExtractPlugin' to enable hot module reloading natively.
any help would be greatly appreciated. There are no errors in the webpack console output just no CSS to call from the HTML file.

const path = require('path');

It appears you've misconfigured
static: {
directory: path.join(__dirname, 'src'),
Your output points to src/dist so it looks like it should be this instead
static: {
directory: path.join(__dirname, 'src/dist'),
On a side note, it's an anti-pattern to have compiled files within your source folder. Generally this structure is recommended.
[repo_root]/
dist/
src/
I'm currently using TS + React to make a simple application with some API requests to a server. When I try to use io-ts to decode the response, webpack responds with Module not found: Error: Can't resolve '../shared/Response' - if I remove the usage of io-ts to decode the response, I don't get that error.
My folder structure is
src
client
PlayerTimer.tsx
<skipped>
server
<skipped>
shared
Phase.d.ts
Response.d.ts
Phase.d.ts contains the following:
import * as t from 'io-ts';
export const PhaseDecode = t.union([
t.literal(1),
t.literal(2),
t.literal(3),
t.literal(4),
t.literal(5),
]);
export type Phase = t.TypeOf<typeof PhaseDecode>
Response.d.ts contains the following:
import * as t from 'io-ts';
import { DateFromISOString as IoDate } from 'io-ts-types/DateFromISOString';
import { PhaseDecode } from './Phase';
const ApiResponseDecode = t.type({
turnNumber: t.number,
phase: PhaseDecode,
breakingNews: t.union([t.string, t.null]),
active: t.boolean,
phaseEnd: IoDate
});
type ApiResponse = t.TypeOf<typeof ApiResponseDecode>
export { ApiResponseDecode, ApiResponse as default };
PlayerTimer.tsx contains a bunch of React components, but this is reproducible with just the following code at the top
import { ApiResponseDecode } from '../shared/Response';
const temp = {};
if (ApiResponseDecode.is(temp)) {
console.log('Webpack fails');
}

I fixed this by moving the type definitions and the io-ts definitions into separate files. I don't really understand why that works but I'll add this incase someone else finds this
I tried to use winston dependency in a cordova application. I know that cordova doesn't have fs module so I don't use file transport from winston. But I found that the build failed with below error:
Module not found: Error: Can't resolve 'fs' in '/ui/node_modules/winston/lib/winston/transports'
# /Users/joeyzhao/dev/mpost/ap-ui/~/winston/lib/winston/transports/file.js 10:11-24
# /Users/joeyzhao/dev/mpost/ap-ui/~/winston/lib/winston/transports/index.js
# /Users/joeyzhao/dev/mpost/ap-ui/~/winston/lib/winston.js
I know that winston doesn't support browser yet. But what I try to understand is whether winston core has fs dependency. It helps me to estimate how much work I should spend on to make winston to work with browser.
Below is how I use winston.
import { createLogger, format, transports } from "winston";
export const defaultTransports = {
console: new transports.Console()
};
export const logger = createLogger({
transports: [defaultTransports.console],
format: format.combine(
format.timestamp(),
exitOnError: false,
exceptionHandlers: [defaultTransports.console],
level: process.env.NODE_ENV === 'production' ? 'info' : 'debug'
});

I'm having a little bit of an issue when I want to implement auth0 on my project.
Whenever I solve one problem I run into another, it's always the same 3 errors :
-require is not a function
-window is not defined
-missing class properties
I've tried solving it by playing with the babelrc, changing the order of the presets
And in webpack I've added the famous as below:
"plugins: [new webpack.DefinePlugin({ 'global.GENTLY': false })],"
in webpack to no avail
I'm providing the package json/ babelrc & web pack without the modifications I cited above so you can see the "base" without the failed attempts at fixing it
Also providing the screenshots with the errors
Thanks in advance

for the errors
this is in babelrc

I ran into this problem while writing for our blog. Our suggested fix is this;
function whatYouRunOnPageLoad() {
if (typeof window !== undefined) {
auth0.parseHash(... etc ...)
}
}
parseHash requires window, which does not exist as part of your render steps. Auth0.js cannot run from serverside, which is what is "accidentally" happening when you try to render it the way you are.
Window error solved by doing:
if(global.window){...}
and later on by just not calling the function I was using at inappropriate times.
Require is not a function solved with:
[new webpack.DefinePlugin({ 'global.GENTLY': false })]
in the webpack config at plugins (dev AND prod, idk why) + importing it with require and not import.
Webpack module error solved by changing the order of the presets in bablerc.
