Karma runner: how to load plugin from file (inlined plugins) - karma-runner

I want to add a plugin from a local file to Karma. I found this example in the documentation (version 0.1):
Documentation to karma runner
// inlined plugins
{'framework:xyz', ['factory', factoryFn]},
require('./plugin-required-from-config')
This is not even valid javascript. When I try the require version of registering I get
Plugin is not registered.
The require version the same.
How is this supposed to be?

It's not so hard.
First of all you should add your plugin to 'plugins' property in karma.config.js after that you could us it.
module.exports = (config) => {
config.set({
frameworks: ['xyz'],
plugins: [
'karma-*',
{
'framework:xyz': ['factory', ()=> console.log('Your code')]
}
]
})
}

Not able to use babel "preset-env" plugin with NextJS

I have a requirement where I am trying to use the Babel plugin "preset-env". This plugin compiles my NextJS project from ES6 to ES5. I have created the .babelrlc file as suggested by NextJS documentation and added my plugin like this:
{
"presets": ["next/babel"],
"plugins": ["#babel/preset-env"]
}
When I try to run my project locally I get this error:
error - ./node_modules/next/dist/client/router.js
Error: Cannot find module '#babel/plugin-preset-env' from '/Users/agastya/Local/testcap/Sample-proj'
- If you want to resolve "#babel/preset-env", use "module:#babel/preset-env"
- Did you accidentally pass a preset as a plugin?
NextJS documentation says "Next.js includes the next/babel preset to your app, which includes everything needed to compile React applications and server-side code. ".
It would be great if someone can explain where/what is the right approach to fix this.
You have to do the following:
// .babelrc file, also could be babel.config.js
{
"presets": [
[
"next/babel",
{
"preset-env": {},
"transform-runtime": {},
"styled-jsx": {},
"class-properties": {}
}
]
],
"plugins": []
}

Babel: root programmatic options

I seem to absolutely not grasp where to put root programmatic options for the babel.
If I have a monorepo and need to tell the different sub packages that they shall look upwards for my babel.config.js then I should put rootMode: "upwards" into the .babelrc of the sub packages, correct? This does not work, because of the resulting error
Error: .rootMode is only allowed in root programmatic options
Somehow I simply can't find any example of where to put/use root programmatic options... Can anyone point me to the right direction?
If you are using Webpack, you need to put it there.
module: {
[..]
rules: [
// Transpile ES6 Javascript into ES5 with babel loader
{
test: /\.jsx?$/,
exclude: [/node_modules/, /json/],
loader: 'babel-loader',
options: {
rootMode: 'upward'
},
},
[..]
],
[..]
},
Otherwise I had the same issue than you, I can't put it in the package.json file using the key babel.
Any API-related options are called programmatic options. Take a look at my discussion with the primary maintainer of Babel: https://github.com/babel/babel/discussions/14405.
It's when you specify them directly to Babel (babel.transformSync(code, programmaticOptions) or to the Babel integration you are using (e.g. babel-loader, which can pass them to its internal babel.transform call). In other words, not in presets or config files. [...]
by #nicolo-ribaudo - Babel core team.
I got this error using my (probably non-standard) monorepo setup where I have top-level subdirectories for each of my packages. No top-level package. When I upgraded to Babel 7, my Jest tests were no longer transforming packages that were yarn linked into the package where I was running Jest.
I added a top-level babel.config.js as part of Babel's monorepo instructions. I had rootMode: "upwards" in these three places:
ui-package/webpack.config.js for transforming the app.
ui-package/babel-jest.js for the tests, where it appeared like:
module.exports = require("babel-jest").createTransformer({
rootMode: "upward",
})
and was referenced from jest.config.js in that same dir like:
transform: {
"^.+\\.jsx?$": "./babel-jest.js",
},
And in /babel.config.js, the newly added top-level babel conf file.
Removing it from the last one removed the error.

Using other NPM packages in own cordova plugin

I created an own cordova plugin for use in an Ionic 3 project.
The js-module requires other npm/node packages (in my case for XML processing).
e.g.
var builder = require('xmlbuilder');
I read X articles about hooks and other crazy stuff, but nothing really helpful.
Is there no easy way to add such a trivial thing to the build-chain just by some simple configuration of the dependencies?
Edit:
Let´s take that simple plugin as example: https://github.com/don/cordova-plugin-hello
The great function in https://github.com/don/cordova-plugin-hello/blob/master/www/hello.js should be able to use the xmlbuilder.
So I changed the file to:
/*global cordova, module*/
var builder = require('xmlbuilder');
module.exports = {
greet: function (name, successCallback, errorCallback) {
cordova.exec(successCallback, errorCallback, "Hello", "greet", [name]);
}
};
I added the module via npm install to the ionic project, but that doesn´t help. How can I make the modules somehow available for the plugins?

import with jest error: Unexpected token import

I've seen similar questions but still can't find a viable solution.
I'm trying to integrate Jest into a working project, which uses import/export default in hundreds of places. The following test does work for Jest using require:
const bar = require('../../flows/foo');
test('adds 1 + 2 to equal 3', () => {
expect(bar.foobar(1, 2)).toBe(3);
});
when export is:
module.exports = {
foobar: foobar,
fizz: fizz
}
The functions I'll want to be testing however are exported using:
export default {
foobar: foobar,
fizz: fizz
};
So when I try to update my test to import:
import foobar from '../../flows/foo';
With export:
export default {foobar: foobar};
I get the error
SyntaxError: Unexpected token import
All it takes:
// run this command (or npm equivalent)
yarn add #babel/core #babel/preset-env
// add babel.config.js
module.exports = {
presets: [
[
'#babel/preset-env',
{
targets: {
node: 'current'
}
}
]
]
};
Jest automatically picks it up, no other configuration required.
You have not set up a .babelrc file in your project, so transpiling is not happening. You need to transpile the ES6+ syntax (import, export, etc) into browser readable ES5.
I ran into this and solved it this way thanks to this GitHub issue post:
If you're using babel to transpile your code then remember to use the transform-es2015-modules-commonjs plugin.
To use it, you'll need to:
Install the plugin for BabelJS by entering this command in the CLI:
npm install --save-dev babel-plugin-transform-es2015-modules-commonjs
Add the plugin to your list of plugins in your babel config
plugins: [
"transform-es2015-modules-commonjs"
]

How to use blueimp-file-upload with webpack?

I'm using blueimp-file-upload in my website, and I'm using webpack to organize my js code.
I installed blueimp-file-upload and jquery.ui.widget from NPM
npm install --save blueimp-file-upload
npm install --save jquery.ui.widget
and I require blueimp-file-upload in my entry file
require('blueimp-file-upload')
but when I run webpack, I get thie error:
ERROR in ./~/blueimp-file-upload/js/jquery.fileupload.js
Module not found: Error: Cannot resolve module 'jquery.ui.widget' in E:\app-parent\cooka-common-web\src\main\resources\static\node_modules\blueimp-file-upload\js
# ./~/blueimp-file-upload/js/jquery.fileupload.js 19:8-22:19
If you're working with images:
Webpack was complaining about some modules that weren't in the blueimp-file-upload package. Here is the way I got this working:
Install missing dependencies:
npm i -S blueimp-load-image
npm i -S blueimp-canvas-to-blob
Configure Webpack:
config.resolve = {
extensions: ['', '.js'],
alias: {
'load-image': 'blueimp-load-image/js/load-image.js',
'load-image-meta': 'blueimp-load-image/js/load-image-meta.js',
'load-image-exif': 'blueimp-load-image/js/load-image-exif.js',
'canvas-to-blob': 'blueimp-canvas-to-blob/js/canvas-to-blob.js',
'jquery-ui/widget': 'blueimp-file-upload/js/vendor/jquery.ui.widget.js'
}
};
Include scripts in your app:
import "blueimp-file-upload/js/vendor/jquery.ui.widget.js";
import "blueimp-file-upload/js/jquery.iframe-transport.js";
import "blueimp-file-upload/js/jquery.fileupload.js";
import "blueimp-file-upload/js/jquery.fileupload-image.js";
Disable both AMD and CommonJS and use the Browser Global jQuery.
/* The jQuery UI widget factory, can be omitted if jQuery UI is already included */
require('imports?define=>false&exports=>false!blueimp-file-upload/js/vendor/jquery.ui.widget.js');
/* The Iframe Transport is required for browsers without support for XHR file uploads */
require('imports?define=>false&exports=>false!blueimp-file-upload/js/jquery.iframe-transport.js');
/* The basic File Upload plugin */
require('imports?define=>false&exports=>false!blueimp-file-upload/js/jquery.fileupload.js');
/* The File Upload processing plugin */
require('imports?define=>false&exports=>false!blueimp-file-upload/js/jquery.fileupload-process.js');
/* The File Upload validation plugin */
require('imports?define=>false&exports=>false!blueimp-file-upload/js/jquery.fileupload-validate.js');
/* The File Upload Angular JS module */
require('imports?define=>false&exports=>false!blueimp-file-upload/js/jquery.fileupload-angular.js');
This is the configuration I'm using to integrate webpack, blueimp-fileupload with angular. Alternatively you can configure in your webpack.config.js as a regex to avoid repeating loaders.
resolve: {
extensions: ['', '.js'],
alias: {
'jquery-ui/widget': 'blueimp-file-upload/js/vendor/jquery.ui.widget.js'
}
}
I had almost identical problem, except that Error announced not 'jquery.ui.widget' but 'jquery/ui/widget'.
For me #Gowrav answer was wrong way.
After days of straying I've solved it in the simple way. Just did:
npm install jquery-ui
The fact is that jquery.fileupload.js searching for its vendor:
But in context where jquery.fileupload.js is trying to import dependency, of course, it can't be found (resolved). So I add it to project instead.
P.S. It's just my opinion about how does all work. But this way has helped me.
jquery.fileupload.js checks for AMD require first which results in this error. You can teach webpack not to use AMD style for this file. (Make sure to npm install imports-loader for this method to work.):
require('imports?define=>false!blueimp-file-upload')
It should correctly register the module as CommonJS and will require the jquery.ui.widget from the right location.
Read more here: http://webpack.github.io/docs/shimming-modules.html#disable-some-module-styles
You can add an alias to jquery.ui.widget's main file - it unfortunately doesn't specify one in its package.json, so webpack can't find it otherwise.
resolve: {
alias: {
"jquery.ui.widget": "node_modules/jquery.ui.widget/jquery.ui.widget.js"
}
},
first install two plugins
npm i blueimp-file-upload --save
npm i jquery-ui --save
then require in web pack
require('blueimp-file-upload/js/jquery.fileupload')
actually you can solve this by changing your webpack config, just add the path to resolve (for example I am using bower)
resolve: {
extensions: [ '', '.js', '.jsx' ],
modulesDirectories: [
'node_modules',
'bower_components',
'bower_components/blueimp-file-upload/js/vendor'
]
}
In webpack 3.x, the syntax will look like this:
{
test: require.resolve("blueimp-file-upload"),
use: "imports-loader?define=>false"
}
