error when attempting to display WebView in vs code - javascript

I am learning how to display a webview on vs code. i used this website and the code below is copied from it. https://mishka.codes/webviews-in-vscode#:~:text=Webviews%20display%20custom%20HTML%2C%20CSS%20%26%20JS%20inside,CSS%20and%20Javascript%20files%20to%20the%20webview.%20
import * as vscode from 'vscode';
export function activate(context: vscode.ExtensionContext) {
let openWebview = vscode.commands.registerCommand('exampleApp.openWebview', () => {
const panel = vscode.window.createWebviewPanel(
'openWebview', // Identifies the type of the webview. Used internally
'Example Page', // Title of the panel displayed to the user
vscode.ViewColumn.One, // Editor column to show the new webview panel in.
{ // Enable scripts in the webview
enableScripts: true //Set this to true if you want to enable Javascript.
}
);
}
context.subscriptions.push(openWebview);
}
function getWebviewContent() {
return `<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Example Webview</title>
</head>
<body>
<h1>This works!</h1>
//Add some custom HTML here
</body>
</html>`;
}
There is an error in the authors extension.ts but it goes away when edit the code so it looks like this (all i added as a ')' and a ';' above the word context):
...
{ // Enable scripts in the webview
enableScripts: true //Set this to true if you want to enable Javascript.
}
);
});
context.subscriptions.push(openWebview);
}
However, when i run the extension the HTML does not show up on the tab in VS code. Can someone help me identify what is wrong? I have left the package-lock.json as is (i used yo code to skaffold the extension). i will post my package.json below

Using any MUI class results in TypeError on unstable_generateUtilityClasses

I don't use JavaScript much so not sure what's going on here. I'm trying to set up a project with React and MUI but served as a static page from an existing web service so using Parcel to produce a single JS file.
Here's package.json:
{
"name": "test",
"version": "1.0.0",
"description": "",
"main": "index.html",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"dist": "parcel build --no-cache --no-minify index.html"
},

},
"dependencies": {

"#mui/utils": "5.10.16",
"react": "17.0.2",
"react-dom": "17.0.2"
}
}
index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<script src="test.js"></script>
<title>Test</title>
</head>
<body>
<div id="root"></div>
</body>
</html>
test.js:
import * as React from 'react';
import { Button } from '#mui/material';
function App() {
return <Button/>;
}
I'm aware this isn't to actually do anything but it doesn't get that far anyway. I run:
$ npm install
$ npm run dist
then open the resulting index.html in a browser. The JS console shows this error:
Uncaught TypeError: Cannot read properties of undefined (reading 'default')

vscode extension development: Add user defined data to vscode extension when package

I'm new to javascript and vscode extension development.
I'm trying to write a vscode extension, doing execSync a python script.
The file structure:
src:
|-- extension.ts
|-- sidebar_test.ts
|-- test_py.py
the content of extension.js file:
import * as vscode from 'vscode';
import * as sidebar from './sidebar_test';
import * as cp from "child_process";
// this method is called when your extension is activated
// your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {
console.log('process cwd: ', process.cwd(), '. env: ', process.env);
console.log('extension path: ', context.extensionPath);
// The command has been defined in the package.json file
// Now provide the implementation of the command with registerCommand
// The commandId parameter must match the command field in package.json
let disposable = vscode.commands.registerCommand('dp2000-upgrade.DP2000Upgrade', function () {
vscode.window.showInputBox({
ignoreFocusOut: true,
placeHolder: 'IP Addr:Port',
}).then(function (input_str) {
let options = { env: {LD_LIBRARY_PATH: '/data/huangxiaofeng/work/tvm0.9dev0/build', PYTHONPATH: '/data/huangxiaofeng/work/tvm0.9dev0/python'} };
cp.execSync(`python ./test_py.py ${input_str}`, options); // TODO: call python script test_py.py
}).then(function (msg) {
console.log('User input:' + msg);
});
});
context.subscriptions.push(disposable);
}
// this method is called when your extension is deactivated
export function deactivate(): void {}
the content of test_py.py:
#! /usr/bin/python3.6

import tvm

import tvm.rpc
print('test_py.py will run...')
ip_addr, ip_port = sys.argv[1].split(':')

When package the project to .vsix, the test_py.py not included.
So my question is: how to include src/test_py.py into the .vsix?

Electron - Typescript - Cannot find module

Trying to build my electron app with typescript generated from the electron-quick-start-typescript project. I have added an additional module called auth.ts which is not recognised when I start the app. I am trying to reference it in renderer.ts with
import { myfunction } from './auth'
However I can see that it is getting converted into js. What could be causing this issue? Why can't my application see my new module?
Additionally here is my package.json file if that helps.

"version": "1.0.0",

Found the answer. For anyone else having the same issue this resolved the issue -
Make sure nodeIntegration is enabled in main.js
webPreferences: {
nodeIntegration: true,
preload: path.join(__dirname, "preload.js"),
},
Index.html
replace:
<script src="./dist/renderer.js"></script>
with:
<script>
require("./dist/renderer.js");
</script>

On running static files are failed to get fetched , ie. /js/vendor.be88a6a7.js returns 404 but it can be fetched by calling /static/js/vendor.be88a6a7.js url. So I have to prepend /static to all the static url paths. But I don't find any webpack.conf file located on that directory.
source code
In vue cli 3 the webpack config file is generated dynamically at runtime. It has been abstracted away. That is the reason you don't see a webpack config file.
You can find the webpack config file here:
<projectRoot>/node_modules/#vue/cli-service/webpack.config.js
This is the file that is dynamically resolved.
The output.publiPath is / by default in the webpack config file. If you want to check want is webpack config file looks like you can use vue inspect command in your command line or via vue ui -> click Tasks -> click inspect. It prints out a serialized format only meant for inspection of the config file.
But if you want to configure the webpack config you can make use of the vue.config.js file.
If you do not have vue.config.js file, then create it in root of your project.
Then add the following:
// vue.config.js
module.exports = {
configureWebpack: {
output: {
publicPath: '/static/'
}
}
}

Electron react build not launching

I'm having some issues while trying to glue together this two things.
Let me give you some context: I'm trying to build a desktop application based on a web application that I've developed in react and it's fully operative and the build process of react is done without any errors nor issues. The problem comes when I try to glue Electron + a React Built Project.
I'm having the following structure:
/ dist
/ node_modules
/ react-mobx-router
/ build
/ static
/ js
main.05ef4655.js
/ css
main.9d8efafe.css
index.html
index.js
At the index.js i have the following code that's basically the sample boilerplate code from electron demo app:
'use strict';
const electron = require('electron');
const app = electron.app;
// adds debug features like hotkeys for triggering dev tools and reload
require('electron-debug')();
// prevent window being garbage collected
let mainWindow;
function onClosed() {
// dereference the window
// for multiple windows store them in an array
mainWindow = null;
}
function createMainWindow() {
const win = new electron.BrowserWindow({
width: 1280,
height: 720,
minWidth: 1280,
minHeight: 720
});
win.loadURL(`file://${__dirname}/react-mobx-router/build/index.html`);
//win.loadURL(`http://localhost:3000`);
win.on('closed', onClosed);
return win;
}
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (!mainWindow) {
mainWindow = createMainWindow();
}
});
app.on('ready', () => {
mainWindow = createMainWindow();
});
I also have to manually change some paths at the react built index.html so it will look like:
<link href="./static/css/main.9d8efafe.css" rel="stylesheet">
instead of:
<link href="/static/css/main.9d8efafe.css" rel="stylesheet">
The second one get's the following errors:
file:///D:/static/css/main.9d8efafe.css Failed to load resource: net::ERR_FILE_NOT_FOUND
main.05ef4655.js Failed to load resource: net::ERR_FILE_NOT_FOUND
The point is that, when I launch the Electron app with yarn start (changing the paths I've told you previously) it launches without any error nor issue but only a blank screen, if I go to the files and look for them, they are correct and the code is inside, bundled and all that react-create-app stuff does.
This is the default configuration of the package.json that comes with Electron and I haven't modified:
{
"name": "app",
"productName": "App",
"version": "0.0.0",
"description": "",
"license": "MIT",
"repository": "user/repo",
"author": {
"name": "",

},

"test": "xo",
"start": "electron .",
"build": "electron-packager . --out=dist --asar --overwrite --all"
},
"files": [
"index.js",

"index.css"
],
"keywords": [

},
"devDependencies": {
"devtron": "^1.1.0",
"electron-packager": "^8.0.0",

"xo": "^0.16.0"
},
"xo": {
"esnext": true,
"envs": [
"node",
"browser"
]
}
}
Also this is the package.json of my React Project:
{
"name": "react-mobx",
"version": "0.1.0",
"private": true,
"devDependencies": {
"custom-react-scripts": "0.0.23",
"mobx-react-devtools": "^4.2.11"
},
"dependencies": {
"mobx": "^3.1.4",
"mobx-react": "^4.1.2",
"mobx-react-router": "latest",
"react": "^15.4.2",
"react-dom": "^15.4.2",
"react-router": "latest"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
Note that the React App is fully functional if I don't make use of Electron.
That's why I ask for your wisdom, mates. I need some light here so I can keep moving on with this project. Hope you can help me with this issue and I've provided you with enough information. If you need more info, just let me know.
Warm regards,
Alex.
I'm no React hero (by a long chalk) but I am able to run, hot reload and release build using the schema set out by this boilerplate: electron-es6-react. I added some conditional code to main.js (below) for builds. There are no doubt much better solutions.
You definitely need to merge your React package.json with Electron's.
var isDev = process.env.APP_DEV ? (process.env.APP_DEV.trim() == "true") : false;
if (isDev) {
// only add this during development
require('electron-reload')(__dirname, {
electron: path.join(__dirname, 'node_modules', '.bin', 'electron')
});
}
