ITypescript is a typescript kernel for the Jupyter notebook (A modified version of IJavascript)

#fromnursetodeveloper 🩺 > 💻

I strive for three things in development: clarity, reusability and beauty.

💡 Currently working on

• ITypeScript - Kernel for Jupyter Notebook, allowing you to play around with TypeScript notebooks
• Steve the Robot (working title): IoT - a cute, mischievous desk robot with his own personality
• SimplyShift - a simple calendar for people with irregular hours
• sturmglas -track your mental weather
• From Scrubs to Slacks - blog series about my career switch, bootcamp experience and things I have learned in the past couple of years (publishing on Medium and Hashnode)

Invalid flag for install location local

Following the readme, when I try to install locally running:

its --ts-install=local

I get the error

Invalid flag for install location local

typechecking (obey tsconfig.json)

How do I get the interpreter to obey tsconfig.json? Right now, it seems to completely ignore typechecking.

I can do something like this

let add = function(x : number, y : number) { return x + y }
add("x", "y")

And it will compile returning "xy".

Cannot find name $TS

Any Ideas?

my tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true 
  }
}

Problem with kernel installation

I'm trying to install typescript kernel, but I'm getting an error: "Error parsing version".

Command npm install -g itypescript run successfully.

But command its --install=local produced the following output

Error parsing version: jupyter core     : 4.5.0
jupyter-notebook : 5.7.8
qtconsole        : 4.5.1
ipython          : 7.6.1
ipykernel        : 5.1.1
jupyter client   : 5.3.1
jupyter lab      : 1.0.2
nbconvert        : 5.5.0
ipywidgets       : 7.5.0
nbformat         : 4.4.0
traitlets        : 4.3.2

I'm working in a virtual environment with the following version of python.

$ python --version
Python 3.7.2

I'm already install javascript and java kernels.

$ jupyter kernelspec list
Available kernels:
  javascript    /Users/petr/Library/Jupyter/kernels/javascript
  python3       /Users/petr/code/practice/cs-education/.venv/share/jupyter/kernels/python3
  java          /usr/local/share/jupyter/kernels/java

Maybe there is some conflict among kernels?

How to uninstall the iTypeScript kernel?

Is there any command to uninstall the iTypeScript kernel?

Issue with variable scoping using (IIFE)

Hello,
This issue related to variable scoping and default behaviour described in the doc.
As described in the doc I cannot re-declare constants and classes or execute the same cell twice.

ITypescript cannot know which cell is currently executing, you cannot redeclare the variables if you define with let or equivalent keywords

IJavaScript has the same behaviour, but I can get around it by using IIFE:

(() => {
    class Something {
        constructor(test){
            console.log(test)
        }
    }
    const test = 23
    console.log(test)
    new Something('test')
})()

Now, I don't know if it is specific to TypeScript, but apparently I cannot use the same trick with ITypeScript:

(() => {
   class Example {
    constructor(test = "test") {
        console.log(test);
    }
   }

    new Example();
    new Example("It works!"); 
})()

On the first call I receive expected result. But if try second time I receive following error:

Error: Conflict with a committed line: 
(() => {
^
TS2349: This expression is not callable.
  Type 'void' has no call signatures.

Support non global jupyter command (configurable jupyter binary command)?

Hi, sorry if this is already supported and described in somewhere else.

Does the itypescript library support invoking jupyter with some other command than jupyter? Namely, I usually handle jupyter library installation by pipenv (fwiw, it's the local npm configuration/installation-ish library for python), and invoke jupyter via pipenv run jupyter.

I think it would be nice if jupyter command can be changed and can be configured e.g. as the command line argument.

Import statement for local modules

There's a problem for transpiling local typescript files.

• its reads local javascript modules
• its reads installed javascript packages
• its CANNOT read local typescript modules

import statements do not seem to be working still. Not sure what the issue is.
To replicate. Create ./test.ts in the same directory as your notebook.

export const test = 'test'

and in your notebook, if you try and import * as test from './test'; and then log out test.test. You'll get an error saying Can not find module './test'`.

• I don't seem to be able to import node core modules such as fs. Even though I've installed @types/node locally.

Dysfunctional

A simple test installing on Anaconda causes virtually every example to fail. It's not sufficient to simply copy files and rename a few things:

1. $TS command don't work
2. imports/modules don't appear to work
3. Writing a class works but only so long as it doesn't inherit from another class
4. Syntax highlighting appears broken
5. TypeScript 2.8 (which is what the Kernel is targeting) has numerous features that are apparently ignored.

This project seems questionable to me and really just a clone with little effort invested in a properly working implementation.

Windows Installation issues

This is the error I get: I can see VS2015 tools seem to be a prerequisite but surely these can be part of the installer?

ols for Visual Studio 2015 (Platform Toolset = 'v140') cannot be found. To build using the v140 build tools, please install Visual Studio 2015 build t
ools.  Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting 
 "Retarget solution". [C:\Users\<<my username>>\AppData\Roaming\npm\node_modules\itypescript\node_modules\zeromq\build\zmq.vcxproj]```

Help wanted: Finding a new owner.

Thank you all for using ITypescript even though I didn't manage it well.
First of all, I'm very sorry for the delay in the update.

I write this issue because I think it is better to transfer ownership to someone else who can update this repository.

When I first uploaded this repository, I didn't know that this many people would use ITypescript. So I believed I could manage it by myself in my leisure time.

But things have changed. I don't use Typescript anymore, so I became paying less attention to ITypescript than before. To make ITypescript better, hence, I concluded that this repository needs someone else to fix listed issues.

Currently, I'm considering 'ownership transfer.' ITypescript should be managed by better people who can pay more attention to it than me. If anyone is interested in developing and updating this repository, please leave a reply. Then, I can transfer the ownership of the repository to the person or organization who replied.

Or, if you have any better options, please leave a comment here.

Once again, thank you for using ITypescript, and sorry for the unhandled issues.

which points to this ticket for node-gyp. Does this mean iTypeScript only works with Python2?

its no such command

After installing itypescript .

I cant run it.

Support top-level await

It seems like top-level await is currently not supported, just like in IJavascript, see n-riesco#173. However, for that there is ijavascript-await (see issue comment).

Installation failure

I'm installing the itypescript in jupyter/base-notebook docker container.
It seems that it is failing in compiling phase:

root@cab675b6394b:~# npm install -g --unsafe-perm itypescript

----------------------------------------------------------------------
Libraries have been installed in:
   /home/node/.npm-global/lib/node_modules/itypescript/node_modules/zeromq/scripts/../zmq/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Generator not supported

The following simple code won't run in iTypeScript notebook.

function* fib(){
    yield 1;
    yield 2;
    let x1 = 1; 
    let x2 = 2;
    while(true){
        let x = x1 + x2;
        x1 = x2;
        x2 = x;
        yield x;
    }
}

The Error message is as below.

Website for samples down

Hey @winnekes :)
Firstly, thanks a lot for your effort!
Secondly, in the usage.md you refer to the ITypescript website, which is offline.
Any recommendations where I can get other samples from?

I use your Typescript kernel in vscode jupyter notebooks. There I have the problem that libraries that are loaded in one code cell aren't available in the next one, which actually makes jupyer notebooks unusable. Console recommends me to add various stuff to my tsconfig file, but that didn't help either.

Best wishes,
Markus

Issue while running the code.

I'm currently getting this issue while running the notebook,

Upgrade to the latest TypeScript version and document a way to do that

Upgrading it to the latest version of TypeScript would be great. This issue is to document the process to do that so anyone can start working on this.

`import module` is not working

I have been struggling to import mongoose into my jupyter notebook with several different errors. I am very new to nodejs and typescript so that could be the reason as I don't understand everything.

Can't parse tsconfig.json but tsc can parse it

Try to put a comment in the tsconfig.json and its will complain. I would agree that it's not valid JSON file but npm/typescript can parse it

{
  "compileOnSave": true,
  "compilerOptions": {
    "lib": [
      "es2017",
      "dom"
    ],
    "outDir": "./build",
    "target": "es6",
    "module": "commonjs",
    "skipLibCheck": true, /* Try to remove it */
    "noImplicitAny": false,
    "allowJs": true,
}

After fixing the comments, I see this:

import mongoose from 'mongoose'
