My very first day trying Playwright and I am having trouble using config. My steps:
init project and install
npm init
npm i -D #playwright/test --save
npx playwright install
create tests/foo.spec.js
const { test, expect } = require('#playwright/test');
test('basic test', async ({ page }) => {
await page.goto('https://playwright.dev/');
const title = page.locator('.navbar__inner .navbar__title');
await expect(title).toHaveText('Playwright');
});
run it
$ npx playwright test
✓ tests/foo.spec.js:3:1 › basic test (3s)
Create playwright.config.js
// #ts-check
const { devices } = require('#playwright/test');
/** #type {import('#playwright/test').PlaywrightTestConfig} */
const config = {
use: {
headless: false,
viewport: { width: 1280, height: 720 },
ignoreHTTPSErrors: true,
video: 'on-first-retry',
},
};
module.exports = config;
run again and get error
$ npx playwright test
Using config at /Users/me/git/left/playwright/playwright.config.js

I am trying to use vue js in rails.
Everything works, except when I tried to use <style> inside .vue component
The exact error is:
./app/javascript/layouts/dashboard.vue?vue&type=style&index=0&lang=scss& (./node_modules/css-loader/dist/cjs.js!./node_modules/vue-loader/lib/loaders/stylePostLoader.js!./node_modules/sass-loader/dist/cjs.js??ref--1-2!./node_modules/style-loader/dist!./node_modules/css-loader/dist/cjs.js??ref--5-1!./node_modules/postcss-loader/src??ref--5-2!./node_modules/sass-loader/dist/cjs.js??ref--5-3!./node_modules/vue-loader/lib??vue-loader-options!./app/javascript/layouts/dashboard.vue?vue&type=style&index=0&lang=scss&)

My environment.js file
const { environment } = require('#rails/webpacker')
const { VueLoaderPlugin } = require('vue-loader')
const vueLoader = require('./loaders/vueLoader')
const vuetifyLoader = require('./loaders/vuetifyLoader')
environment.plugins.prepend('VueLoaderPlugin', new VueLoaderPlugin())
environment.loaders.prepend('vue', vueLoader)
environment.loaders.prepend('vuetify', vuetifyLoader)
const resolver = {
resolve: {

}
environment.config.merge(resolver)
module.exports = environment
VuetifyLoader.js file
module.exports = {
test: /\.s(c|a)ss$/,

},
},
],
}
install these two plugins.
npm install --save node-sass
npm install --save sass-loader
So, the problem was with fiber and indentedSyntax. After removing those two, everything works as expected. I was getting lots of error related to scss like
like
expected new line
in sass files inside node_modules. I don't know, why vuetify recommends to use fiber in sass loader.
I am trying to record video with audio using videojs-record and my application is in angular 7. I have followed their wiki. Here is the link below
https://github.com/collab-project/videojs-record/wiki/Angular

I am new to angular. So any help on this will be appreciated. Thanks in advance.
No worries guys, I have fixed it by myself. After doing some research I came to know that as I was using angular cli to serve and build so I have used ngx-build-plus (as ng eject is deprecated in angular 7 and will be removed from angular 8) to execute webpack config using angular cli. This webpack config was missing before. This may help someone that's why just shared. Thank you.
you can't use in that way. if you are using angular cli to serve or build then you have to create a partial webpack config file and serve or build it through angular cli. You should follow below things.
Please visit below link and install the package and follow the instruction to configure your stuffs.
https://www.npmjs.com/package/ngx-build-plus
Your webpack.partial.js should look like
const webpack = require('webpack');
module.exports = {
resolve: {
alias: {
// place your config
}
},
plugins: [
// place your config
],
}
and scripts in package.json file should look like
"scripts": {
"ng": "ng",
"start": "ng serve --extra-webpack-config webpack.partial.js",
"build": "ng build --extra-webpack-config webpack.partial.js",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e",
"build:prod": "ng build --prod --extra-webpack-config webpack.partial.js",
"build:stage": "ng build --prod -c staging --extra-webpack-config webpack.partial.js",
"build:dev": "ng build -c development --extra-webpack-config webpack.partial.js"
},
Then you can serve your app using npm start
To build you use npm run build:dev || npm run build:stage || npm run build:prod
based on the environment.
I am trying to use Webpack with Babel to compile ES6 assets, but I am getting the following error message:
You may need an appropriate loader to handle this file type.
| import React from 'react';
| /*
| import { render } from 'react-dom'
Here is what my Webpack config looks like:
var path = require('path');
var webpack = require('webpack');
module.exports = {
entry: './index',
output: {
path: path.join(__dirname, 'dist'),
filename: 'bundle.js',
publicPath: '/dist/'
},
module: {
loaders: [
{
test: /\.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/
}
]
}
}
Here is the middleware step that makes use of Webpack:
var webpack = require('webpack');
var webpackDevMiddleware = require('webpack-dev-middleware');
var config = require('./webpack.config');
var express = require('express');
var app = express();
var port = 3000;
var compiler = webpack(config);
app.use(webpackDevMiddleware(compiler, {
noInfo: true,
publicPath: config.output.publicPath
}));
app.get('/', function(req, res) {
res.sendFile(__dirname + '/index.html');
});
app.listen(port, function(err) {
console.log('Server started on http://localhost:%s', port);
});
All my index.js file is doing is importing react, but it seems like the 'babel-loader' is not working.
I am using 'babel-loader' 6.0.0.
You need to install the es2015 preset:
npm install babel-preset-es2015
and then configure babel-loader:
{
test: /\.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ['es2015']
}
}
Make sure you have the es2015 babel preset installed.
An example package.json devDependencies is:
"devDependencies": {
"babel-core": "^6.0.20",
"babel-loader": "^6.0.1",
"babel-preset-es2015": "^6.0.15",
"babel-preset-react": "^6.0.15",
"babel-preset-stage-0": "^6.0.15",
"webpack": "^1.9.6",
"webpack-dev-middleware": "^1.2.0",
"webpack-hot-middleware": "^2.0.0"
},
Now configure babel-loader in your webpack config:
{ test: /\.js$/, loader: 'babel-loader', exclude: /node_modules/ }
add a .babelrc file to the root of your project where the node modules are:
{
"presets": ["es2015", "stage-0", "react"]
}
More info:
babeljs.io - using babel with webpack
babeljs.io - docs on .babelrc
react-webpack-cookbook - configure react with webpack
a react-webpack-example repo
If you are using Webpack > 3 then you only need to install babel-preset-env, since this preset accounts for es2015, es2016 and es2017.
var path = require('path');
let webpack = require("webpack");
module.exports = {
entry: {
app: './app/App.js',
vendor: ["react","react-dom"]
},
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, '../public')
},
module: {
rules: [{
test: /\.jsx?$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader?cacheDirectory=true',
}
}]
}
};
This picks up its configuration from my .babelrc file:
{
"presets": [
[
"env",
{
"targets": {
"browsers":["last 2 versions"],
"node":"current"
}
}
],["react"]
]
}
BABEL TEAM UPDATE:
We're super 😸 excited that you're trying to use ES2015 syntax, but instead of continuing yearly presets, the team recommends using babel-preset-env. By default, it has the same behavior as previous presets to compile ES2015+ to ES5
If you are using Babel version 7 you will need to run npm install #babel/preset-env and have "presets": ["#babel/preset-env"] in your .babelrc configuration.
This will compile all latest features to es5 transpiled code:
Prerequisites:
Webpack 4+
Babel 7+
Step-1:: npm install --save-dev #babel/preset-env
Step-2: In order to compile JSX code to es5 babel provides #babel/preset-react package to convert reactjsx extension file to native browser understandable code.
Step-3: npm install --save-dev #babel/preset-react
Step-4: create .babelrc file inside root path path of your project where webpack.config.js exists.
{
"presets": ["#babel/preset-env", "#babel/preset-react"]
}
Step-5: webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
mode: 'development',
entry: path.resolve(__dirname, 'src/index.js'),
output: {
path: path.resolve(__dirname, 'output'),
filename: 'bundle.js'
},
resolve: {
extensions: ['.js', '.jsx']
},
module: {
rules: [{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
},
{
test: /\.css$/i,
use: ['style-loader', 'css-loader'],
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: "./public/index.html",
filename: "./index.html"
})
]
}
In my case, I had such error since import path was wrong:
Wrong:
import Select from "react-select/src/Select"; // it was auto-generated by IDE ;)
Correct:
import Select from "react-select";
Due to updates and changes overtime, version compatibility start causing issues with configuration.
Your webpack.config.js should be like this you can also configure how ever you dim fit.
var path = require('path');
var webpack = require("webpack");
module.exports = {
entry: './src/js/app.js',
devtool: 'source-map',
mode: 'development',
module: {
rules: [{
test: /\.js$/,
exclude: /node_modules/,
use: ["babel-loader"]
},{
test: /\.css$/,
use: ['style-loader', 'css-loader']
}]
},
output: {
path: path.resolve(__dirname, './src/vendor'),
filename: 'bundle.min.js'
}
};
Another Thing to notice it's the change of args, you should read babel documentation https://babeljs.io/docs/en/presets
.babelrc
{
"presets": ["#babel/preset-env", "#babel/preset-react"]
}
NB: you have to make sure you have the above #babel/preset-env & #babel/preset-react installed in your package.json dependencies
You probably forgot to add .js extension to your file.
Component -> Component.js
This makes me feel stupid, but I want to share for anyone that got frustrated like me: I used webpack.dev.js but didn't specify that as the config file! When running Webpack run with:
webpack --config webpack.dev.js
And it suddenly worked ;)
Just adding on another reason such error showed up in Angular.. was because I checked for html file in list of styles:
#Component({
selector: ...,
templateUrls: 'xyz.html',
stylesUrls: ['xyz.html'] // problem
})
Addressing wrong file type raises this error
As question doesn't specify if it was for angular, react, or react-native. I am posting this for react-native and it may be implied on others too. The reason was that it wasn't able to understand the syntax specified by loader. e.g. tsx, jsx. One solution I found in this article after lots of exploration. When we use external library that was using jsx and you configured your project with tsx, it won't understand jsx and will give you to add appropriate loader. So, you can fix that by following code in your app.json file.
"web": {
"build": {
"babel": {
"include": [
"name-of-my-shared-package-here"
]
}
}
}
By replacing name-of-my-shared-package-here with your package name that is causing the issue will solve this issue. You can check the package name in error that is causing this issue.
Outdated babel packages on Jan 3, 2023
Please install these list of packages for configuration with babel.
$ npm add -D #babel/core babel-loader #babel/preset-env #babel/preset-react
and add below code .babelrc file
{
"presets": [
"#babel/preset-env",
"#babel/preset-react"
]
}
I used #khizer webpack configuration in my application
Credit goes to This answer. As I have have been gone through the best answer of this solution and it tooks my 2-3 hours. I hope other don't waste same amount of time.
When using Typescript:
In my case I used the newer syntax of webpack v3.11 from their documentation page
I just copied the css and style loaders configuration form their website.
The commented out code (newer API) causes this error, see below.
module: {
loaders: [{
test: /\.ts$/,
loaders: ['ts-loader']
},
{
test: /\.css$/,
loaders: [
'style-loader',
'css-loader'
]
}
]
// ,
// rules: [{
// test: /\.css$/,
// use: [
// 'style-loader',
// 'css-loader'
// ]
// }]
}
The right way is to put this:
{
test: /\.css$/,
loaders: [
'style-loader',
'css-loader'
]
}
in the array of the loaders property.
This one throw me for a spin.
Angular 7, Webpack
I found this article so I want to give credit to the Article
https://www.edc4it.com/blog/web/helloworld-angular2.html
What the solution is:
//on your component file. use template as webpack will treat it as text
template: require('./process.component.html')
for karma to interpret it
npm install add html-loader --save-dev
{
test: /.html$/,
use: "html-loader"
},
Hope this helps somebody
Just add this code webpackmix.js
mix.js('resources/js/app.js', 'public/js')
.postCss('resources/css/app.css', 'public/css', [
require('tailwindcss'),
]).vue();
Gulp plugin gulp-ruby-sass(https://github.com/sindresorhus/gulp-ruby-sass) giving not compiling, the error message in terminal coming like this 👇
Error: must provide pattern
Here is the gulpfile.js details
var gulp = require('gulp'),
uglify = require('gulp-uglify'),
sass = require('gulp-ruby-sass');
gulp.task('styles', function (argument) {
gulp.src('sass/app.scss')
.pipe(sass())
.pipe(gulp.dest('css/'));
});
The gulp-ruby-sass syntax has been changed:
instead of: it is now:
gulp.task('styles', function (){ gulp.task('styles', function (){
gulp.src('sass/app.scss') return
.pipe(sass()) sass('sass/app.scss')
.pipe(gulp.dest('css/') .pipe(gulp.dest('css/')
; ;
}); });
Please check it out and mark your problem as solved.
The official gulp-ruby-sass documentation says it should be done like this:
var gulp = require('gulp');
var sass = require('gulp-ruby-sass');
gulp.task('sass', function () {
return sass('source/file.scss')
.on('error', sass.logError)
.pipe(gulp.dest('result'));
});
Install libsass because it runs much faster than ruby sass ,
it works with node
npm install gulp-sass --save-dev`
Install gulp load plugins because it does so much and loads
plugins from your json and you dont need to declare in your gulpfile
(carefull how many you use because if you load too many it hinders
performance)
npm install --save-dev gulp-load-plugins
var gulp = require('gulp'),
$ = require('gulp-load-plugins')({
pattern: ['gulp-*', 'gulp.*'],
replaceString: /\bgulp[\-.]/,
lazy: true,
camelize: true
});
gulp.task('libsass', function () {
gulp.src('sass/app.scss')
.pipe($.sass({errLogToConsole: true}))
.pipe($.autoprefixer({
browsers: ['last 2 versions'],
cascade: false
}))
.pipe($.sourcemaps.write('app/css/map'))
.pipe(gulp.dest('app/css'))
});
