I am trying to render a calendar from https://github.com/wix/react-native-calendars
I am getting a failed to compile error:
./node_modules/react-native-calendars/src/expandableCalendar/asCalendarConsumer.js
Module parse failed: Unexpected token (11:8)
You may need an appropriate loader to handle this file type.
| render() {
| return (
| <CalendarContext.Consumer>
| {(context) => (
| <WrappedComponent
I think is based on my webpack setup:
// webpack.config.js
module.exports = {
plugins: ["#babel/plugin-syntax-dynamic-import"],
resolve: {
alias: {
'react-native$': 'react-native-web'
},
},
rules: [
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
presets: ['babel-preset-env', 'babel-preset-stage-0'],
plugins: ["#babel/plugin-syntax-dynamic-import"],
}
},
{
test: /\.js$/,
loader: 'babel-loader',
options: {
presets: ['babel-preset-env', 'babel-preset-stage-0'],
}
},
{
test: /\.ttf$/,
loader: "url-loader", // or directly file-loader
include: path.resolve(__dirname, "node_modules/react-native-vector-icons"),
},
]
}
But I am not really an expert on webpack.
The library seems to work with React Native Web - so what am I doing wrong that is causing me to not have it work with my setup?
Found the solution. Make sure to INCLUDE it in babel-loader. To fix it do the following:
1- Make sure to include the package folder in the babelLoader configuration in webpack.config.js as
include: [path.resolve(appDirectory, 'node_modules/react-native-calendars'), ...]
NOTE: Don't forget to also include all the directories that require babel-loader.
2- (Might need it)- You might need to go to node_modules/react-native-calendars/src/calendar/index.js and to node_modules/react-native-calendars/src/agenda/index.js and REMOVE the propTypes declarations and the ViewPropTypes import from react-native on lines 2, 20, and 32 on both files. Here's how */agenda/index.js is supposed to look like. Until the devs fix this, avoid updating the package or you will lose the changes. (I am including this because it happened to me right after step 1 so just in case)

I want to integrate responsive-loader into my Nuxt.js project which runs in SPA mode. (Optional I want to add Vuetify Progressive Image support also).
It will be a static hosting with Netlify.
Versions:
"nuxt": "^2.3.4"
"responsive-loader": "^1.2.0"
"sharp": "^0.21.1"
I found some solutions how to do it (https://stackoverflow.com/a/51982357/8804871) but this is not working for me.
When I run npm run build
I get an error message: "TypeError: Cannot set property 'exclude' of undefined"
My build section looks the following:
build: {
transpile: [/^vuetify/],
plugins: [
new VuetifyLoaderPlugin()
],
extractCSS: true,
/*
** Run ESLint on save
*/
extend(config, { isDev, isClient, isServer }) {
// Default block
if (isDev && isClient) {
config.module.rules.push({
enforce: 'pre',
test: /\.(js|vue)$/,
loader: 'eslint-loader',
exclude: /(node_modules)/
})
}
if (isServer) {
config.externals = [
nodeExternals({
whitelist: [/^vuetify/]
})
]
}
// Default block end
// here I tell webpack not to include jpgs and pngs
// as base64 as an inline image
config.module.rules.find(
rule => rule.loader === "url-loader"
).exclude = /\.(jpe?g|png)$/;
/*
** Configure responsive-loader
*/
config.module.rules.push({
test: /\.(jpe?g|png)$/i,
loader: "responsive-loader",
options: {
min: 350,
max: 2800,
steps: 7,
placeholder: false,
quality: 60,
adapter: require("responsive-loader/sharp")
}
});
}
}
The error is probably found in this section:
config.module.rules.find(
rule => rule.loader === "url-loader"
).exclude = /\.(jpe?g|png)$/;
Like said I get this error message: "TypeError: Cannot set property 'exclude' of undefined".
I run this project along with vuetify. I also would like to enable the Progressive image support together with responsive loader. Does anybody know how to setup both rules together?
https://github.com/vuetifyjs/vuetify-loader#progressive-images
The easiest way to integrate responsive-loader into a Nuxt.js project is to use this module: https://www.npmjs.com/package/nuxt-responsive-loader
Disclaimer: I created the module
The problem with your config that it relies on rule.loader property but rule can be defined in use or oneOf config sections as well.
Another one problem is that nuxt internal config has several rules with url-loader(for images, videos, fonts ...).
In your case the rule, you tried to find, has use section and url-loader is defined there, that's why your find function found nothing and threw this error:
{
"test": /\.(png|jpe?g|gif|svg|webp)$/,
"use": [{
"loader": "url-loader",
"options": {
"limit": 1000,
"name": "img/[hash:7].[ext]"
}
}]
}
About responsive-loader, you should remove extensions you want to process with responsive-loader from url-loader rule to avoid unexpected behavior and conflicts, here is extend function working example:
extend(config, ctx) {
let imgTest = '/\\.(png|jpe?g|gif|svg|webp)$/';
// find by reg ex string to not rely on rule structure
let urlRule = config.module.rules.find(r => r.test.toString() === imgTest);
// you can use also "oneOf" section and define both loaders there.
// removed images from url-loader test
urlRule.test = /\.(svg|webp)$/;
config.module.rules.push({
test: /\.(png|jpe?g|gif)$/,
loader: "responsive-loader",
options: {
// place generated images to the same place as url-loader
name: "img/[hash:7]-[width].[ext]",
min: 350,
max: 2800,
steps: 7,
placeholder: false,
quality: 60,
adapter: require("responsive-loader/sharp")
}
})
}
Yes, it looks dirty, but I think it's only way for now to change some loader.
What about vuetify - I think both loaders will conflict with each other and probably the solution is to use single loader that will work with your images.
Hope it helps.
Update for Nuxt >= 2.4.0:
They modified the rules array please update the following line:
let imgTest = '/\\.(png|jpe?g|gif|svg|webp)$/i';
Then the code should work normally again.
I have successfully used the webfonts-loader package to generate a font and class-definitions for icons, but it isn't served by my nuxt dev server. There is a styletag in my head with:
#font-face {
font-family: "TopLoggerIcons";
src: url("/myfont.eot?#iefix") format("embedded-opentype"), url("/myfont.woff2") format("woff2");
}
But the requested http://localhost:3010/myfont.woff2 gives a 404. I had this working in the nuxt version before 2.0 (and before webpack 4), where the file is served from http://localhost:3010/_nuxt/myfont.woff2. The font is currently also served from there, but the path in the font-face declaration is wrong. I'm wondering what has changed here removing the (required?) _nuxt part in the path.
In my nuxt.config.js file I have:
build: {
extend(config, ctx) {
config.module.rules.push({
test: /plugins\/icons\.js$/,
use: ['vue-style-loader', 'css-loader', 'webfonts-loader'],
})
},
}
Now according to the example on the webfonts-loader lib I need to use the MiniCssExtractPlugin.loader instead of the vue-style-loader, but that doesn't work. I read here that it is internally used by nuxt, but i don't know how to add it here.
Hope anyone has an idea where to look...
Ok, just figured it out: you have to use the publicPath option of the webfonts-loader package:
extend(config, ctx) {
config.module.rules.push({
test: /plugins\/icons\.js$/,
use: [
'vue-style-loader',
'css-loader',
{
loader: 'webfonts-loader',
options: {
publicPath: config.output.publicPath,
},
}
],
})
}
The config.output.publicPath is /_nuxt/.
I am getting the following error when I am trying to run "gulp" in my vue.js project after I have added an image tag in my Home.vue component [ <img class="img-fluid" src="../images/logoWhite.png"> ] :

throw er; // Unhandled stream error in pipe.

I read that this error might be caused by babel and how it is configured in webpack.config.js. After trying some solutions listed, I still haven't managed to get it work. I have also tried to create a '.babelrc' file with the presets conditions for babel, but still it didn't work.
This is how 'webpack.config.js' file looks like:
var webpack = require('webpack')
module.exports = {
entry: [
'./src/main.js'
],
output: {
path: "/dist/js",
publicPath: "/dist/",
filename: "app.js"
},
watch: true,
module: {
loaders: [
{
test: /\.js$/,
// excluding some local linked packages.
// for normal use cases only node_modules is needed.
exclude: /node_modules|vue\/src|vue-router\//,
loader: 'babel'
},
{
test: /\.scss$/,
loaders: ['style', 'css', 'sass']
},
{
test: /\.vue$/,
loader: 'vue'
}
]
},
babel: {
presets: ['es2015'],
plugins: ['transform-runtime']
},
resolve: {
modulesDirectories: ['node_modules']
}
}
In package.json, I have the following packages as my devDependencies for babel:
"babel-core": "^6.1.21",
"babel-loader": "^6.1.0",
"babel-plugin-transform-runtime": "^6.1.18",
"babel-preset-es2015": "^6.13.2",
"babel-runtime": "^6.3.13"
Thanks in advance guys!
I had the same problem and my solution was to use 'file-loader'
Install:
npm install --save-dev file-loader
Add the module rule to your webpack.config.js
{ test: /\.(png|jpg|gif)$/, loader: 'file-loader?name=./images/[name].[ext]' }
CSS file:
.content {
background-image: url('./images/background.jpg');
}
The template section of a .vue file is loaded using vue-html-loader, which will attempt to load local resources (such as image tag src values) using require(<resource>)(details).
The error above is due to the fact that you don't have a webpack loader setup to handle .png files, to fix it you'd need to install and configure a suitable loader - something like this, with url-loader, should work:
{ test: /\.png$/, loader: "url-loader?mimetype=image/png" }
I use some npm packages in my project. Two of them have the wrong main-field. Is it possible to override them?
I use webpack. I found a solution here.
This works for the main field but I also need a css-file from the same package. I refer it with ~package/css/style.css in my index.scss file. With the solution above it resolves the path with path/to/main.js/css/style.css (with main.js) instead of path/to/css/style.css (without main.js).
I could refer it directly ../node_modules/path/to/css/style.css but I think thats ugly.
So is there an other solution with webpack or npm to override this main field?
-- EDIT --
I use bootstrap-treeview as package. I refer it in index.scss like so
#import '~bootstrap-treeview/src/css/bootstrap-treeview.css';. This works.
When I add 'bootstrap-treeview': path.join(_path, 'node_modules', 'bootstrap-treeview', 'src', 'js', 'bootstrap-treeview.js') as alias in webpack import 'bootstrap-treeview'; works but the css not (as describes above).
-- EDIT 2 --
webpack.conf.js:
resolve: {
extensions: ['', '.js'],
modulesDirectories: ['node_modules'],
alias: {
// bootstrap-treeview alias
'bootstrap-treeview': path.join(_path, 'node_modules', 'bootstrap-treeview', 'src', 'js', 'bootstrap-treeview.js')
}
},
module: {
loaders: [
{
test: /\.css$/,
loaders: [
'style-loader',
'css-loader?sourceMap',
'postcss-loader'
]
},
{
test: /\.(scss|sass)$/,
loader: 'style-loader!css-loader?sourceMap!postcss-loader!sass-loader?outputStyle=expanded&sourceMap=true&sourceMapContents=true
}
]
}
index.scss see above.
Error with bootstrap-treeview alias:
Module not found: Error: Cannot resolve 'file' or 'directory' /home/ekf/develop/generator-angular-webpack/node_modules/bootstrap-treeview/src/js/bootstrap-treeview.js/src/css/bootstrap-treeview.css in ...
Error without alias:
Module not found: Error: Cannot resolve module 'bootstrap-treeview' in ...
just in case
webpack scss loader config
module: {
loaders: [
{
test: /\.css$/,
exclude: /node_modules/,
loader: "style-loader!css-loader"
},
{
test: /\.scss$/,
exclude: /node_modules/,
loader: "style-loader!css-loader!sass-loader"
}
]
}
The problem is that your alias points directly to the JS file, instead of pointing to the common ancestor of both the JS and the CSS. It's nice and convenient to be able to import Treeview from "bootstrap-treeview" but it leads to the problem you're describing.
Instead, you could specify a higher level alias:
resolve: {
alias: {
// bootstrap-treeview alias
'bootstrap-treeview': path.join(_path, 'node_modules', 'bootstrap-treeview', 'src')
}
},
and get the JS as import Treeview from "boostrap-treeview/js/bootstrap-treeview.js". This allows you to get the CSS as require("bootstrap-treeview/css/bootstrap-treeview.css").
You might be able to get clever about it and tell Webpack to look for CSS files in ~/css/ and JS files in ~/js/ but that would be adding more magic for (IMHO) little gain.

Before using this plugin everything was working fine. As i intend to output different bundle for css, i need to fix this issue.
Found issue in github but it did not help:
https://github.com/webpack/extract-text-webpack-plugin/issues/132
well updating node worked for me. I did this by running "brew update" and "brew upgrade" command, as i am using homebrew as a package manage in mac.
Following instruction in the git link provide in my question resulted in error as i was installing webpack and webpack-dev-server globally. I removed it and only had local copy which did the trick at the end.
command to list global copy of node modules installed:
npm list -g --depth=0
I use this command to remove global copy:
npm uninstall -g {replace_with_package_name}
command to check local copy:
npm list --depth=0
