url-loader without webpack? - babeljs

I have a component library that will be shipping with a few small assets (images). Those assets are imported into various components in the library.
The build script uses babel (without webpack) to transpile the js(x) to a build directory, and is currently dumping the images into build/assets/images.
This works when testing the build, but when using the component in another project (using webpack) the component tries to refer the node_modules folder:
Example component:
import myImage from './assets/images/myImage.png';
const MyComponent = () => (
<img src={myImage} />
);
export MyComponent;
Usage:
import MyComponent from 'myLibrary/MyComponent';
export default () => (
<MyComponent />
);
The error message:
myImage.png:1 GET http://localhost:9001/node_modules/myLibrary/assets/images/myImage.png 404 (Not Found)
As I understand the 'best' way to include assets is to use the url-loader so they're converted to data uri's. However, trying to use the url-loader without Webpack isn't working:
babel.config.js
...
plugins: [
[
"url-loader",
{
"extensions": ["png", "jpg", "jpeg", "gif", "svg", "pdf"],
"limit": 0
}
]
]
...
Error: Cannot find module 'babel-plugin-url-loader'

I found this and it works for PNG and SVG files - worked perfectly for what I needed!

Nuxt 3 "component library" module does not expose mixins of exported components in NX monorepo

I'm facing a problem with my Nuxt 3 component library.
It contains several Vue components which are then added to the exported components
export const useComponents = (nuxt: Nuxt) => {
const __dirname = dirname(fileURLToPath(import.meta.url));
let componentsDirectory = join(__dirname, "../", '/components');
nuxt.hooks.hook("components:dirs", (dirs) => {
dirs.push({
path: join(componentsDirectory, "../", 'atoms'),
prefix: 'base',
});
dirs.push({
path: join(componentsDirectory, "../", 'layout'),
prefix: 'base',
});
dirs.push({
path: join(componentsDirectory, "../", 'molecules'),
prefix: 'base',
});
})
}
However, some of those components are using mixins, which are located next to the components and relatively imported.
When using that component library in my application, it does not find the mixins and I'm getting this exception:
when using import loginButtonsMixing from "~/src/molecules/loginButtonsMixing.js";
[vite:load-fallback] Could not load
/home/user/workspace/my-project/apps/my-app/molecules/loginButtonsMixing.js
(imported by
../../../libs/general/base/src/molecules/LoginButtons.vue): ENOENT: no
such file or directory, open
'/home/user/workspace/my-project/apps/my-app/molecules/loginButtonsMixing.js'
It looks inside the app directory, instead of the library directory.
And when I'm using import loginButtonsMixing from "./loginButtonsMixing.js";
Could not resolve './loginButtonsMixing.js' from
../../../libs/base/src/molecules/LoginButtons.vue at error

/home/user/workspace/my-project/node_modules/rollup/dist/es/shared/rollup.js:22119:26
The path looks more or less correct, but rollup seems to fail.
How do I tell the Nuxt module to expose them as well?

Getting this error with the #metaplex-foundation/js-next SDK

Currently working on a react app and I'm getting this error after installing metaplex.
My react-scripts version is 4.0.3
./node_modules/#metaplex-foundation/js-next/dist/esm/programs/token/gpaBuilders/TokenGpaBuilder.mjs
Can't import the named export 'ACCOUNT_SIZE' from non EcmaScript module (only default export is available)
I found out the solution in the git of metaplex here. I will leave you here the whole answer anyway.
Getting Started with Metaplex and CRA 5
This example sets up a new React app with Metaplex using "Create React App" (CRA) version 5 — i.e. using Webpack 5.
This example has been generated using the following steps:
Create a new project using the "Create React App" command.
npx create-react-app getting-started-react-cra5
cd getting-started-react-cra5
Install the Metaplex and the Solana SDKs.
npm install #metaplex-foundation/js #solana/web3.js
Install some polyfills.
npm install assert util crypto-browserify stream-browserify
Install and use react-app-rewired.
# Installs react-app-rewired.
npm install react-app-rewired
# Replaces "react-scripts" with "react-app-rewired" in package.json scripts.
sed -i '' 's/react-scripts /react-app-rewired /g' package.json
Override Webpack 5 configurations.
Create a new file to override Webpack 5 configurations.
touch config-overrides.js
Copy the following code inside the new config-overrides.js file.
const webpack = require("webpack");
module.exports = function override(webpackConfig) {
// Disable resolving ESM paths as fully specified.
// See: https://github.com/webpack/webpack/issues/11467#issuecomment-691873586
webpackConfig.module.rules.push({
test: /\.m?js/,
resolve: {
fullySpecified: false,
},
});
// Ignore source map warnings from node_modules.
// See: https://github.com/facebook/create-react-app/pull/11752
webpackConfig.ignoreWarnings = [/Failed to parse source map/];
// Polyfill Buffer.
webpackConfig.plugins.push(
new webpack.ProvidePlugin({ Buffer: ["buffer", "Buffer"] })
);
// Polyfill other modules.
webpackConfig.resolve.fallback = {
crypto: require.resolve("crypto-browserify"),
stream: require.resolve("stream-browserify"),
util: require.resolve("util"),
assert: require.resolve("assert"),
fs: false,
process: false,
path: false,
zlib: false,
};
return webpackConfig;
};
Update your browser requirements.
Update the browserslist object of your package.json to include the following production requirements.
"browserslist": {
"production": [
- ">0.2%",
- "not dead",
- "not op_mini all"
+ "chrome >= 67",
+ "edge >= 79",
+ "firefox >= 68",
+ "opera >= 54",
+ "safari >= 14"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
},
That's it!
You should not use #metaplex-foundation/js-next SDK, the actual repo is #metaplex-foundation/js, the name was changed and the updated repo is this, so try using #metaplex-foundation/js instead

Jest: Cannot use import statement outside a module

I got an error when I run test using Jest, I tried to fix this error for 2 hours. But, I couldn't fix it. My module is using gapi-script package and error is occurred in this package. However, I don't know why this is occurred and how to fix it.
jest.config.js
module.exports = {
"collectCoverage": true,
"rootDir": "./",
"testRegex": "__tests__/.+\\.test\\.js",
"transform": {
'^.+\\.js?$': "babel-jest"
},
"moduleFileExtensions": ["js"],
"moduleDirectories": [
"node_modules",
"lib"
]
}
babel.config.js
module.exports = {
presets: [
'#babel/preset-env',
]
};
methods.test.js
import methods, { typeToActions } from '../lib/methods';
methods.js
import { gapi } from "gapi-script";
...

What is wrong with my setting?
As of this writing, Jest is in the process of providing support for ES6 modules. You can track the progress here:
https://jestjs.io/docs/en/ecmascript-modules
For now, you can eliminate this error by running this command:
node --experimental-vm-modules node_modules/.bin/jest
instead of simply:
jest
Be sure to check the link before using this solution.
I solved this with the help of Paulo Coghi's answer to another question -
Does Jest support ES6 import/export?
Step 1:
Add your test environment to .babelrc in the root of your project:
{
"env": {
"test": {
"plugins": ["#babel/plugin-transform-modules-commonjs"]
}
}
}
Step 2:
Install the ECMAScript 6 transform plugin:
npm install --save-dev #babel/plugin-transform-modules-commonjs
Jest needs babel to work with modules.
For the testing alone, you do not need jest.config.js, just name the testfiles xxx.spec.js or xxx.test.js or put the files in a folder named test.
I use this babel.config.js:
module.exports = function (api) {
api.cache(true)
const presets = [
"#babel/preset-env"
]
return {
presets
}
}
Adding "type": "module" in package.json or using mjs as stated in other answers is not necessary when your setup is not too complicated.
I have also faced the same issue and this was resolved by adding following command-line option as a environment variable.
export NODE_OPTIONS=--experimental-vm-modules npx jest //linux
setx NODE_OPTIONS "--experimental-vm-modules npx jest" //windows
Upgrading Jest (package.json) to version 29 (latest as of now) solved this problem for me.

Babel 7 and babel-polyfill

After updating to babel 7 beta, looks like babel polyfill does not transpile before bundle. I updated all scoped packages like this one "#babel/polyfill": "7.0.0-beta.36". And changed imports for two files from import 'babel-polyfill' to import '#babel/polyfill'. How to use babel/pollyfill with babel env and babel 7. Should I use babel/polyfill when use useBuiltIns: 'usage', with targets?
.babelrc.js
const nodeEnv = process.env.NODE_ENV || 'development'
let presetEnvConfig, plugins
if (nodeEnv === 'test'){
presetEnvConfig = {targets: {node: 'current'}}
plugins = ['istanbul']
} else {
presetEnvConfig = {
targets: {
browsers: ['last 2 versions', 'ie >= 11']
},
modules: false
}
plugins = ['react-hot-loader/babel']
}
const config = {
presets: [
['#babel/preset-env', presetEnvConfig],
'#babel/react',
'#babel/stage-2'
],
plugins,
}
types.js
import keyMirror from '../../../utils/keyMirror'
export default keyMirror({
Unassign: null,
Reassign: null,
QuickAssignment: null,
}, 'TagAssignmentTypes')
index.js
<Assignment
assignee={assignee}
tagId={tagId && tagId.toString(16)}
assignmentType={assignmentTypes.Reassign}
onRequestClose={() => this.setState({isAssignmentInProgress: false})}
onChange={onChange}
/>
#babel/polyfill is a wrapper package which only includes imports of stable core-js features (in Babel 6 it also included proposals) and regenerator-runtime/runtime, needed by transpiled generators and async functions. This package doesn't make it possible to provide a smooth migration path from core-js#2 to core-js#3: for this reason, it was decided to deprecate #babel/polyfill in favor of separate inclusion of required parts of core-js and regenerator-runtime.
Instead of
import "#babel/polyfill";
you should use those 2 lines:
import "core-js/stable";
import "regenerator-runtime/runtime";
Don't forget install those dependencies directly!
npm i --save core-js regenerator-runtime
Change
#babel/stage-2 to #babel/preset-stage-2
The following worked for me, add
**.babelrc**
{
"presets": [
["#babel/env"]
]
}
**app.js**
import "core-js/stable";
import "regenerator-runtime/runtime";
*Install as pointed by gianmarco*
npm i --save core-js regenerator-runtime

Karma preprocessor not running

My karma.conf.js includes:
plugins: [
'karma-jasmine',
'karma-phantomjs-launcher',
'karma-ng-html2js-preprocessor'
],
preprocessors: {
'../../mypath/*.html': ['ng-html2js']
},
ngHtml2JsPreprocessor: {
moduleName: 'templates'
},
(I've tried without specifying any plugins, too.)
My devDependencies include:
"karma-ng-html2js-preprocessor": "^0.2.0"`
My tests include:
beforeEach(module('templates'));
These give the error:
Module 'templates' is not available!
Running karma with --log-level debug, I do not see any [preprocessor.html2js] entries. (I do get Loading plugin karma-ng-html2js-preprocessor.)
What am I doing wrong?
The issues were that the templates must be listed under files as well, and that the glob pattern in preprocessors must match. This is implied by the documentation.
files: [
'../../Scripts/angular-app/directives/*.html',
// .js files
],
preprocessors: {
'../../Scripts/angular-app/**/*.html': ['ng-html2js']
},
Note that **/*.html does not match parent directories of the basePath.
karma start --log-level debug will display DEBUG [preprocessor.html2js] entries when everything is correct.
I was also able to remove the plugins section.
To get the correct cache ID, I used:
ngHtml2JsPreprocessor: {
// Load this module in your tests of directives that have a templateUrl.
moduleName: 'templates',
cacheIdFromPath: function (filepath) {
return filepath.substring(filepath.indexOf('/Scripts/angular-app/'));
}
},
If a template references a custom filter, the filter must be loaded in files and the filter's module must be loaded in your directive tests.
