I am doing a little project where i have prepared the back end in python and the graphic user interface woth HTML, CSS & JS.
The python script doesn't require any external librariesand the only thing that it does is opening a JSON file with the data processed, since it's a game the results are casually generated, and because of this I don't have to pass any parameters to the script.
The problem is that I don't know how to trigger the script so it generates the json that i can access trough JabaScript.
the scheme of the project is this:
index.html
pages (folder)
newGame.html
loadGame.html
rules.html
python (folder)
python_script1.py
python_script2.py
python_script3.py
main.py
specifically i have to trigger the script once the user has loaded the newGame page or the loadGame one.
(obiuvsly the js isn't node.js is actual client-side JavaScript)
I obiuvsly did some research and i found the pyodyde open source project does what i want, the fact is that i can't figure out how to connect the interface file with the back-end one with this resource.
solution
Ok, with some other research i found out how to solve my problem.
But firstable I want to thank you guys for recommending me the PyScript library.
The problem I was having is that i needed to connect a python file within the pyscript tag.
At first i tought that I had to import it with the import keyword and than executing the file.
But than I discovered that the py-script tag has an src attribute and you can link all the external files that you want.
So, in the end, iall i had to do was to connect my file is this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>newGame</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<py-script src= "./python scripts/test_file.py"></py-script>
<script src="script.js"></script>
</body>
<script defer src="https://pyscript.net/alpha/pyscript.js"></script>
</html>
There is a new library called PyScript (it can help you run python in your HTML), all you need to do to install the cli is doing this command:
pip install pyscript-cli (This command will install the cli not the library).
then you should do this command:
pyscript wrap python_file.py (NOTE: this will convert the python file to an html file so the python file name would be the name of the html file)
And it should be done.
The HTML code would be this:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Homepage</title>
<link rel="stylesheet" href="https://pyscript.net/alpha/pyscript.css"/>
<script defer src="https://pyscript.net/alpha/pyscript.js"></script>
</head>
<body>
<py-script>
Code here
</py-script>
</body>
</html>
But than, once i typed in the command and created the html file from the python script, how do I connect it to the "newLevel" page?

I installed jquery with NPM and I'm trying to incorporate it into an existing webpage.
In the console I see the following error:
In my code, I have a skeleton like this:
<!DOCTYPE html>
<html lang='en'>
<head>
<title></title>
<link rel='stylesheet' type = 'text/css' href='css/' />
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<meta charset="UTF-8">
</head>
<body>
<script type='text/javascript' src='node_modules/jquery/src/jquery.js'></script>
<script type= 'text/javascript' src='javascript/script.js'></script>
</body>
</html>
Looking into the file itself and the error in the console, I see the following reflected both ways:
I'm not very familiar with define statements but from what I've seen crawling up and down google. It looks like I need to install a bundler like webpack?
But I feel like that's unneccessary for simply adding jQuery to a project without a cdn.
Am I barking up the wrong tree? Or is this a common issue?
Using npm install jquery is how you use jquery with node.js on the server itself.
It doesn't sound like that's what you're trying to do - rather that you want to use it on a webpage that is being served locally by your node server. To do that, download jQuery manually and include it in your sites file structure.
- index.html
- /scripts
- jquery-3.2.1.min.js
Then in your HTML reference it locally:
<script src="scripts/jquery-3.2.1.min.js"></script>
I'm having trouble with some components running in MS IE 10/11.
And according to this arcticle from Angular.io (https://angular.io/docs/ts/latest/guide/browser-support.html) I need to import an external script.
<script src="node_modules/core-js/client/shim.min.js"></script>
Which I placed in my index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<base href="/">
<link rel="icon" type="image/x-icon" href="/assets/favicon.ico">
...
<script src="../node_modules/core-js/client/shim.min.js"></script>
</head>
<body>
<app-root></app-root>
</body>
</html>
But when i build for production it doesn't add it to the build, it just leaves it there ending in a script not found error when running the application.
I'm probably missing something but I don't know what.
Thanks in advance!
In your .angular-cli.json file, locate (or create) the "scripts" key in the definition for your app, and add an entry in the array for the shim.js script, e.g.:
"scripts": [
"../node_modules/core-js/client/shim.min.js"
],
Restart your ng serve or rebuild your bundles and you should be good to go.
Hope this helps!
You need to add CSS files and JS files in the angular-cli.json file. If you are not using angular-cli in this case you need to configure in the build tool which you are using

I want to use the debugger included in Webstorm to run my project. I'm
using Angular2 and TypeScript. I need to place breakpoints into my typescript files.
Basically, my index.html just imports some .js files and starts my
app by calling a function named bootstrap defined in another .js file (transpiled from a .ts file !).
<!DOCTYPE html>
<html lang="en">
<head>
<base href="/">
<meta charset="UTF-8">
<title></title>
<!-- 1. Load libraries -->
<!-- IE required polyfills, in this exact order -->
<script src="../node_modules/es6-shim/es6-shim.min.js"></script>
<script src="../node_modules/systemjs/dist/system-polyfills.js"></script>
<script src="../node_modules/angular2/es6/dev/src/testing/shims_for_IE.js"></script>
<script src="../node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="../node_modules/systemjs/dist/system.src.js"></script>
<script src="../node_modules/rxjs/bundles/Rx.js"></script>
<script src="../node_modules/angular2/bundles/angular2.dev.js"></script>
<script src="build/core/system.config.js"></script>
<script src="build/core/moduleLoader.js"></script>
<script src="build/core/bootstrap.js"></script>
<script src="../node_modules/angular2/bundles/router.dev.js"></script>
<script>
bootstrap();
</script>
</head>
<body>
<app-view>Loading...</app-view>
</body>
</html>
bootstrap is defined as follow :
const bootstrap:()=>Promise<void>= async function() {
await ModuleLoader.loadAll();
System.import('core/app').then(null, console.error.bind(console));
};
window.bootstrap = bootstrap;
When I run my index.html in debug mode, an error is thrown,
bootstrap() is not defined.
When I run the app inside a browser, it works well. Have I missed some configuration ?
I've installed the jetbrains plugin (I'm using chrome) and configured the port. I can see the "Loading..." on my browser.
EDIT
Maybe a usefull information :
I'm using node. Into my main server-side script, I set up express and do some configuration. When I'm trying to debugging, my server is listening but on another port (8080). The debugger uses the port 63343.
You can start a JavaScript debug session for any URL - you just need to specify it in the JavaScript run configuration. If you app is running on localhost:8080, then use that URL in the JavaScript debug configuration.
Another important point: make sure you generate source maps when compiling your TypeScript code.
The reason to have src and dist folders is pretty clear: we change source code commit it to repository and use compiled dist files for production.
But what could you recommend for development? We still want to keep src clean from compiled file and make it very fast to review the changes.
Before we just transpiled SAAS into CSS and put it into source and keep JS files as they are(without compiling in one file or coping them to dist). And now we decided to rethink the concept.
we are doing web development, but I think question is more broad.
If I well understood, you are looking for a development architecture/workflow to directly serve you sources to the browser (and use DevTools edition features btw). In fact, there are 2 things to do to achieve this.
1) For compiled/transpiled languages (SAAS, LESS, TypeScript, ...) and unsupported languages (ES6, ES7), you will need to compile/transpile them on the client side. Tools like LESS.js, typescript.js, BabelJS are great to do that. I don't know any SAAS compiler implementation in Javascript.
2) Then, you need 2 different html indexes. For example index.hml for production and dev.html for development.
index.html with bundled (dist) files:
<!DOCTYPE html>
<html>
<head>
<title>App Title</title>
<link rel="stylesheet" type="text/css" href="dist/app.bundle.css">
<script type="text/javascript" src="dist/app.bundle.js"></script>
</head>
<body>
...
</body>
</html>
dev.html with all sources (src) files:
<!DOCTYPE html>
<html>
<head>
<title>App Title (Dev)</title>
<link rel="stylesheet/less" type="text/css" href="src/file1.less" />
<script type="text/javascript" src="src/file1.js"></script>
<script type="text/javascript" src="src/file2.js"></script>
<script type="text/javascript" src="src/file3.js"></script>
<script type="text/javascript" src="lib/less.js"></script>
</head>
<body>
...
</body>
</html>
This way, developers access the web app using, let's say http://localhost/dev.html and can enjoy all the goodness to have sources right in the browser. Without taking care of the compilation.
To apply such an architecture you may need to adapt client and/or server code and also build tools to work in both mode (prod and dev).
Hope I helped.
I'm just starting out with typescript. I wanted to try working with this mankala example from within Visual Studio. Eventually I got it working but I had to include all of the .js files that were generated from .ts files in my default.htm file. The .htm file in the example only included one file - the one that contained the entry point. I'm guessing that there's something set wrong in my configuration that I'm compensating for by the multiple .js includes. Can anyone tell me what I'm doing wrong?
More details follow...
Here's what the original .htm file looked like:
<!DOCTYPE html>
<html>
<head>
<title>Mankala</title>
<meta http-equiv="X-UA-Compatible" content="IE=9"/>
<script type="text/javascript" src="game.js"></script>
<link rel="stylesheet" type="text/css" href="play.css"/>
</head>
<body id="bod" onload="Mankala.testBrowser()">
<div class="hscore">Human: <span id="humscore">0</span></div>
<div class="cscore">Computer: <span id="compscore">0</span></div>
</body>
</html>
And this is what my modified .htm file looked like:
<!DOCTYPE html>
<html>
<head>
<title>Mankala</title>
<meta http-equiv="X-UA-Compatible" content="IE=9"/>
<script type="text/javascript" src="base.js"></script>
<script type="text/javascript" src="Driver.js"></script>
<script type="text/javascript" src="Features.js"></script>
<script type="text/javascript" src="Game.js"></script>
<script type="text/javascript" src="geometry.js"></script>
<script type="text/javascript" src="Position.js"></script>
<link rel="stylesheet" type="text/css" href="play.css"/>
</head>
<body id="bod" onload="Mankala.testBrowser()">
<div class="hscore">Human: <span id="humscore">0</span></div>
<div class="cscore">Computer: <span id="compscore">0</span></div>
</body>
</html>
To create the project I created a default ( not quite empty ) typescript project, deleted the automatically created app.ts file from that project and then added 6 new .ts files with the same names as the .ts files in the example. Then I copied the .ts files from the example over the new .ts files that were created by VS. I replaced the automatically generated app.css file with the play.css file from the example and replaced the contents of the automatically generated default.htm file with the contents of the play.htm from the sample. This didn't run but after I added the additional .js files to default.htm it did.
I'm using Visual Studio 2012 Express for the Web and the typescript 0.8.3.1 VS extension. I'm using the Chrome browser on windows7.
The difference here is how the compiler got invoked.
When you build the Mankala sample, assuming you read the README, you ran
tsc Driver.ts -out game.js
The -out flag tells the compiler to concatenate the compilation into one big .js file. However, the default behavior in Visual Studio projects is to build side-by-side, i.e. base.ts creates base.js, Features.ts creates Features.js, etc.
You can fix your project file by adding a <TypeScriptOutFile>game.js</TypeScriptOutFile> element to the project in the same <PropertyGroup> as the other TypeScript settings (near line 57 in a default new project). Be sure to add to both the Debug and Release PropertyGroup elements if you want the same behavior in both compilation settings, or create a new non-conditional PropertyGroup.
