I have as simple "hello world" project and I want to test the famous hélloWorld function.
The project is structured like this:
├── package.json
├── spec
│ ├── helloWorldSpec.js
│ └── support
│ └── jasmine.json
└── src
└── helloWorld.js
And the file content:
package.json
{
"name": "jasmineTest",
"version": "0.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "BSD-2-Clause",
"dependencies": {
"jasmine": "~2.1.0"
}
}
spec/helloWorldSpec.js
// var helloWorld = require('../src/helloWorld.js');
describe('Test', function() {
it('it', function() {
helloWorld();
});
});
src/helloWorld.js
function helloWorld() {
return "Hello world!";
}
// module.exports = helloWorld;
spec/support/jasmine.json
{
"spec_dir": "spec",
"spec_files": [
"**/*[sS]pec.js"
],
"helpers": [
"helpers/**/*.js"
]
}
My problem:
When I run npm install jasmine is downloaded.
=> ok
When I run ./node_modules/jasmine/bin/jasmine.js
I have the error ReferenceError: helloWorld is not defined ReferenceError: helloWorld is not defined
My Question:
How can I access the method helloWord contained in src/helloWorld.js in the test scope without using module.exports = xxx.
A solution is to use Grunt.
Create a GruntFile.js containing:
module.exports = function (grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
jasmine: {
src: ['src/**/*.js'],
options: {
specs: ['spec/**/*Spec.js'],
vendor: []
}
}
});
grunt.loadNpmTasks('grunt-contrib-jasmine');
};
Update package.json with grunt, grunt-cli and grunt-contrib-jasmine dependencies
{
"name": "jasmineTest",
"version": "0.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "BSD-2-Clause",
"dependencies": {
"jasmine": "~2.1.0",
"grunt": "~0.4.5",
"grunt-cli": "~0.1.13",
"grunt-contrib-jasmine": "~0.8.1"
}
}
Update npm dependencies:
npm update
And relaunch test using grunt and not directly jasmine:
./node_modules/grunt-cli/bin/grunt jasmine
And you got:
Running "jasmine:src" (jasmine) task
Testing jasmine specs via PhantomJS
Test
- it...
log: Spec 'Test it' has no expectations.
✓ it
1 spec in 0.008s.
>> 0 failures
Done, without errors.
According to Jasmine staff :
You don't need to specify your source files in the config - just require them in from your spec files.
https://github.com/jasmine/jasmine-npm/issues/49
But then, you do need to use export.
This is not a Jasmine issue but vanilla Javascript. You want to call a method from another file so you need to export and require it.
Why don't you want to ?

I am trying to load the Css, Images and fonts using the webpack. Here is my webpack.config.js
const path = require('path');
module.exports = {
entry: './src/index.js',
mode: 'development',
output: {
filename: "main.js",
path: path.resolve(__dirname,"dist")
},
module:{
rules:[
{
test: /\.css$/i,
use: ['style-loader', 'css-loader'],
},
{
test: /\.(png|svg|jpg|jpeg|gif)$/i,
type: "asset/resource",
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/i,
type: "asset/resource",
},
],
},
};
This is my package.json
{
"name": "restaurant-page",
"version": "1.0.0",
"description": "",
"private": true,
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"watch": "webpack --watch",
"build": "webpack"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"css-loader": "^6.2.0",
"style-loader": "^3.2.1",
"webpack": "^5.51.1",
"webpack-cli": "^4.8.0"
},
"dependencies": {}
}
This is my index.js. When I uncomment the ./styles.css import I get the
main.js:290 Uncaught Error: Automatic publicPath is not supported in this browser in chrome console and my js imports doesn't work but it dosen't throw me error while building project when I run npm run build commmand in terminal. I tried using css import in each js module-- in home.js etc--file but that also doesn't work.
// import './style.css';
import { homeContent, removeIntroContent } from './Modules/home.js';
import { aboutContent, removeAboutContent } from './Modules/about.js';
import { reviewsContent, removeReviewContent } from './Modules/reviews.js';
const home = document.getElementById("home-btn");
const review = document.getElementById("review-btn");
const about = document.getElementById("about-btn");
homeContent();
home.addEventListener("click",()=>{
removeReviewContent();
removeAboutContent();
const id = document.getElementById("intro-content");
if(id != null) return;
homeContent();
});
review.addEventListener("click",()=>{
removeAboutContent();
removeIntroContent();
const id = document.getElementById("reviews");
if(id != null) return;
reviewsContent();
});
about.addEventListener("click",()=>{
removeReviewContent();
removeIntroContent();
const id = document.getElementById("about");
if(id != null) return;
aboutContent()
});
I have pushed the code to github if anyone want to look at file structure
Here is the link
ps: If I use the link tag to add css to html it works exactly as I want it to but that defeats the purpose of using webpack
I am having trouble with Webpack as well and I came across your question. I don't have a sure solution to your problem, but I hope to steer you in the right direction.
At first glance, I am wondering if editing your package.json file to use your webpack-config when you run 'npm run build' instead of the default webpack config. This could help activate the loaders you are trying to use, or atleast populate error messages that would allow you to investigate further. Editing your package.json would look like:
"scripts": {
"test": "echo \\\"Error: no test specified\\\" && exit 1",
"watch": "webpack --watch",
"build": "webpack --config ./webpack-config.js"
}
Your dependencies make sense and your file path for style.css seems correct, so I am wondering if Webpack does not know how to load your styles, fonts, images without your config file.
Can read more about Webpack configuration here.
https://webpack.js.org/configuration/
Hope I was able to help, good luck! If you have any further questions I'd be happy to help, as I'm learning Webpack too.
I'm trying to biuld bundling through rollup.js in VSCode.
My directory:
----MyProject
--------\node_modules
-----------\.bin
-----------\rollup
--------index.js
--------index.html
--------bundle.js
--------package-lock.json
--------package.json
In my .html file I have connection with bundle.js, all changes which I'm doing in index.js must automatically be updated in bundle.js. But it's only working when I run in terminal this command: rollup index.js --file bundle.js
My package.json:
{
"name": "npm",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"rollup": "^2.34.2"
}
}
What do I need to do to make this system works automatically?
Firstly, I didn't have config file, so I've created rollup.config.js:
import serve from 'rollup-plugin-serve'
import livereload from 'rollup-plugin-livereload'
const watch = process.env.ROLLUP_WATCH
export default {
input: 'src/index.js',
output: {
file: 'dist/bundle.js',
format: 'iife'
},
plugins: [
watch && serve('dist'),
watch && livereload()
]
}
Then I added these 2 scripts into package.json:
"build": "rollup -c",
"dev": "rollup -c -w"
And run in terminal: npm run dev

I'm following the official Webpack getting started guide and I get an error on the Using a Configuration section. It says to create a webpack.config.js file with:
const path = require('path');
module.exports = {
entry: './src/index.js',
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist')
}
};
I then run the following command:
npx webpack --config webpack.config.js
The error I get is:
Cannot find module '/Users/Documents/Web_Development/tone/webpack.config.js'
The guide does not seem to give any ideas of what could be wrong here. Also my code editor is telling me there is an error with const path = require('path'); saying "Expected a JSON Object, array or literal;
My Directory structure:
webpack.config.json
package.json.lock
package.json
node_modules/
dist/
index.html
main.js
src/
index.js
package.json:
{
"name": "tone",
"version": "1.0.0",
"description": "",
"private": true,
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},

"devDependencies": {
"babel-core": "^6.26.3",
"webpack": "^4.29.3",
"webpack-cli": "^3.2.3"
},
"dependencies": {
"lodash": "^4.17.11"
}
}
The solution was to change the webpack.config.json file to webpack.config.js.
You have to make sure that the webpack.config.js file is in the root of your project.
I am trying to implement local modules in my application
1.Project root folder i have created folder named test with a file named index.js
module.exports = {
myFunction:function(){
console.log('ok');
}
}
2.Added the following in package.json in the root folder
"dependencies": {
"test-module": "file:test"
}
3.When i try to import var module = require('test-module'); in app.js i got this error
Cannot find module 'test-module'
you can provide a path to a local directory that contains a package
{
"name": "baz",
"dependencies": {
"bar": "file:../foo/bar"
}
}
and perform npm install -s or npm install --save reference
To add on #Blaze answer, if you follow the steps (Local Paths) to install a local module, it will sort out for you the local dependency in your package.json:
npm i ./test --save
That will produce the correct local dependency entry in your dependencies in the root package.json:
"test-module": "file:test"
assuming test-module is the name in the local dep package.json.
This is how it should look like:
Make sure your test folder has a package.json.
test/package.json should have a "name" field with the value "test-module" (ie, same name as the dependency in your root package.json.
My files:
test/package.json
{
"name": "test-module",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC"
}
test/index.js
module.exports = {
t:() => console.log('t')
};
package.json
{
"name": "t",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"test-module": "file:test"
}
}
app.js
t = require('test-module');
t.t();
This is working for me.
Ive searched this for over an hour now and no ones post helped me with my problem so i need to post i guess lol
I have some pretty simple code for a grunt task im trying to run but im getting an error.
module.exports = function(grunt){
grunt.initconfig({
pkg: grunt.file.readJSON ('package.json'),
uncss: {
dist: {
files: {
'css/style.css' : ['index.html']
}
}
}
});
grunt.loadNpmTasks('grunt-uncss');
grunt.registerTask('default',['uncss']);
};
my package file is as follows:
{
"name": "Grunt",
"version": "1.0.0",
"description": "grunt",

"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"

}
}
The Error im getting is:
