pytocs | Converts Python source to C | Transpiler library

I am trying to transpile an ES6 express app using Parceljs.

Trying to run the parcel dev server using yarn parcel index.js displays that it is running at localhost:1234 but the page is blank. It also generates the following output when trying to run node dist/index.js:

I get a broken image in the browser when rendering the path to images saved on backend (using express). I know there are similar questions, but non could solve the issue for me.

I have this on my server.ts file running in http://localhost:5000:

I am using DOJO toolkit and after upgrading to use the closure compiler, I noticed I needed to transpile to ES5 BEFORE the dojo build util does it's job in order to take advantage of newer ES6+ features.

So I am using babel-maven-plugin to accomplish this.

Everything is working fine with the exception that the ...spread operator is not transpiling.

Do I need to download the @babel/preset-env package as well to set the preset option? or is there an option I am missing?

I would like to transpile JavaScript into LinkScript. I have started like this:

I'm running into an issue with the node-fetch library. The new version (3.0.3) has "type": "module" in its package.json. This is a problem because I transpile my code from ES6 to regular js which uses require and then I get ...firebase_datasource.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. I can use an earlier version of node-fetch that doesn't contain "type": "module" in its package.json in its package.json, but that's not a solution. What's the correct way to handle this?

This works fine in .pxd file:

I raised an issue https://github.com/facebook/jest/issues/11504 against the jest project, which I think is responsible for maintaining babel-jest. Transpilation totally fails after adding apparently harmless and error-free code.

However, there are a lot of layers to the transpilation of a Typescript Next project, so I am unsure if this is the correct place to file the issue and matches with the likely source of the failure.

Does this issue seem like it matches with the babel-jest project or should I file it somewhere else?

BUG

I found in a complex Next Typescript project that adding a handful of lines in one file was enough to break babel-jest transpilation and create runtime errors in a completely different file.

In commit 04c4c7b, after checking out the clean project and running yarn I am able to get passing tests with yarn run test. The passing source tree is at https://github.com/cefn/jest-transpile-failure-repro/tree/04c4c7b7013e8b88c25d3ab2a7d4a33ccd3fb191

However, after adding the handful of lines which you can see in commit 25703fc the babel-jest transpiler seems to effectively break making tests impossible to run, and a totally unrelated file starts to get runtime errors during the test which make no sense like...

I have a big project in php 5 and it's well documented. Now, I want to migrate to php 7.2 and I have already checked the compatibility using phpstan and every thing is alright. So, I wonder if there is a tool that could automatically transform the php 5 annotations to php 7 (like functions declarations and variables )?

Thanks in advance

I want to be very clear that I am not asking how to transpile a C# UWP app to a JavaScript UWP app. I am, rather, attempting to extract portions of an existing C# UWP application that can be migrated to create a Node.js server. I attempted to use Bridge.NET, but my impression (correct me if I'm wrong) is that there is no way to build an app that targets both UWP and .NET. If there is, this alone would likely solve my problem.
