On this fiddle https://jsfiddle.net/k2c5upfo/1/, extern modules are called using the import method. I don't use node on my project. I'd like to convert all these import files into regular javascript files. How can I built them without using node.js ?
import * as THREE from "https://cdn.jsdelivr.net/npm/three#0.118.2/build/three.module.js";
import { OrbitControls } from "https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/controls/OrbitControls.js";
import { EffectComposer } from 'https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/postprocessing/EffectComposer.js';
import { ShaderPass } from 'https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/postprocessing/ShaderPass.js';
import { RenderPass } from 'https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/postprocessing/RenderPass.js';
import { ClearPass } from 'https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/postprocessing/ClearPass.js';
import { MaskPass, ClearMaskPass } from 'https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/postprocessing/MaskPass.js';
import { CopyShader } from 'https://cdn.jsdelivr.net/npm/three#0.118.2/examples/jsm/shaders/CopyShader.js';
For example, I was able to call 'OrbitControls.js' on a older version of three.js by simply add another file. Can I still use this method ? Thank you
EDIT :
I managed to convert my workflow using es6 modules. I've been wondering if there's a way to only import specific modules. My generated output file has the same weight with theses two different lines.
import {Scene, PerspectiveCamera, WebGLRenderer, CylinderBufferGeometry, MeshNormalMaterial, Mesh} from "../node_modules/three/build/three.module.js";
import * THREE from "../node_modules/three/build/three.module.js";
Is there a way to only have the part of code that I need in my final output ? Thank you.
Using global scripts is actually deprecate since r117. At the end of the year, using ES6 modules is the only way of importing example files.
I don't use node on my project.
Not sure I understand this sentence. The above fiddle is unrelated to node.js. You can import ES6 modules directly in HTML files as long as you put the import statements into script tags that look like so:
<script type="module">
</script>
This approach is also used by the official examples.

I'm trying to import a JSON file on my Vite app, whose paths are dynamically generated. So the import path for this JSON includes variables.
I know it's possible to do it with require, but I'm working with Svelte, and I cant use requires.
You can use a dynamic import() statement for that. This will return a promise, which has to be awaited, though. E.g.
<script lang="ts">
import meta from './meta.json';
const filePromise = import(/* #vite-ignore */ `./${meta.file}.json`);
</script>
{#await filePromise then file}
{file.property}
{/await}
There are some limitations to dynamic imports in Vite so the application can be built properly. The #vite-ignore comment silences a warning output about these limitations.
I'm trying to make a luxon example in stackblitz, but the imports are not working.
The luxon library and its types are added, and it is imported at the beginning of the file:
However I get the message that it is undefined!
I tried to find other examples of stackblitz (google: "luxon stackblitz") however none of them seem to work or use and old version, which is imported via CDN
Do I somehow have to add the whole luxon library to the project?
Code (super simple)
// Import stylesheets
import './style.css';
import { DateTime } from 'luxon';
// Write TypeScript code!
const appDiv: HTMLElement = document.getElementById('app');
appDiv.innerHTML = `luxon sample -->"${DateTime.now()}"<--`;
Since the JSX plugin is deprecated I've been struggling to have Babel handle my jsx files. I finally managed to convince SystemJS to load my app with:
System.import('scripts/app.jsx!babel')
But this doesn't import any imported jsx files like:
import Login from './components/Login' // File is Login.jsx
With the old plugin this worked but now I am not sure how to get it working now.
One step in the right direction would be adding this to your config:
"packages": {
"components": { // Packages could of course be replaced with what you want
// to affect. Even "." is valid.
meta: {
'*.jsx': {
loader: 'babel'
}
}
}
}
This allows you to load files as such: import .. from './components/Login.jsx'.
You could take this one step further by adding "defaultExtension": "jsx" under "components". I'd only use this if the folder/modules was jsx-only though. That would allow you to import as import .. from './components/Login' as you wanted to.
my code is like:
import Render from './AppeRender';
import { Component } from 'react';
export default class appDB extends Component {
render () {
return Render.call(this, this.props, this.state);
}
}
and what i'm getting is:
Module parse failed: /home/projects/node_modules/DB/Db.js Line 5: Unexpected token
You may need an appropriate loader to handle this file type.
Note: Error only comes in web setup, it's working fine in android and in IOS i haven't tried yet.
Does anyone have any idea regarding this.
I think what is wrong here is that you using import twice (and the second one is a destructure.
Try this instead:
import { Component } from 'react';
import Render from './AppeRender';
You can bind Component in one import.
The second import could have been changed to a straight destructure:
const { Component } = React;
But, there is no reason to do this if you are only using Component.
Using import on an Object is not really correct (however, it might work with some implementations), I assume that is why the error was occurring.
I am trying out the new Angular 2 Forms. My import statements are as follows:
import {bootstrap, onChange, NgIf, Component, Directive, View, Ancestor} from 'angular2/angular2';
import {formDirectives, NgControl, Validators, NgForm} from 'angular2/forms';
import {RegExpWrapper, print, isPresent} from 'angular2/src/facade/lang';
import {reflector} from 'angular2/src/reflection/reflection';
import {ReflectionCapabilities} from 'angular2/src/reflection/reflection_capabilities';
The 'angular2/angular2' resolves fine, but none of the other "from" locations resolve. The error is:
Cannot find module 'angular2/forms'.
All of these components are currently in my node_modules directory. If I put in the full path:
import {formDirectives, ControlDirective, Validators, TemplateDrivenFormDirective} from 'C:/Users/Deb/node_modules/angular2/forms';
then it works. However, I should not need to use the full path. Am I missing something when I set up the tsconfig or is there something else wrong?
Problem was that the example application did not match with the version of Angular 2 currently available for download.
If anyone is interested, I now have a working example of Angular2 forms with TypeScript and Visual Studio Code here:
https://github.com/DeborahK/AngularU2015-Angular2Forms
Hope this helps anyone else standing on the "bleeding edge".
