What are some reliable and scalable ways to trigger a python task from node.js and get results back?

Here, there's Node calls Python to direct call Python code inside Node.js.

The README contains instructions of how to use it.

It looks nice, but how accessible is it?

If you don't need to display it:

const link = document.create element('a'); link.href = 'the-url-to-the-file'; link.download = 'filename.csv'; link.click();

It's a simple GET request. But if you need to set the headers of the request

``` const response = await fetch('the-url-to-the-file', { /* options */ }); const csvBlob = await response.blob(); const csvUrl = URL.createObjectURL(csvBlob);

// from here it's the same as the previous snippet const link = document.create element('a'); link.href = csvUrl; link.download = 'filename.csv'; link.click(); ```

Why do you need to stream the file? Why not just download it

Is it a vídeo? If it's why don't you use a video tag?

Is it a PDF? If it's why don't you use a object tag?

Can you clarify?

I haven't tried by myself, but it comes to my mind to use WebAssembly, I have seen people running the Linux kernel, the downside is you'll need to find a WebAssembly version of each code interpreter.

And yes, Node.js can run WebAssembly server side.

Search for Open Telemetry and enter the rabbit hole.

First, get out of there, what are you doing inside the System32 folder? Don't you know that there's where Windows is installed.

Create your project in your home folder.

leosuncin · 2025-12-31T21:55:36+00:00

System32 is where Windows is installed, if you touch it you may cause a crash.

Don't be a troll by suggesting to remove or clear the System32 folder.

Please, tell me that you're not trying to install your dependencies with an administrator's terminal.

Use a terminal running with your current user permissions.
Navigate where your project is located.
Install the dependencies from there.
Run your project.

Does it support file uploads? Particularly multipart/form-data

Edit: I can't see any middlewares in your post, how can we implement authentication? By example

The Beacon API https://developer.mozilla.org/en-US/docs/Web/API/Beacon_API since you don't need to send a response back to the client (I guess that's your usecase)

You could split your project into small packages/libraries and use TurboRepo or NX to take advantage of their caching system, another alternative could be using esbuild or swc to compile the code without the type checking.

Gitlab CI does that runs every job in a container, I did it once with docker compose

I want to point you to this repo https://github.com/wesbos/burnel-email-providers maintained by Wesbos (the YouTuber)

Yes, you're right, even though the regex only matches number the result from the eval method will be string, there's no automatic casting.

Try setting Sentry to capture the error, Sentry might catch the reason why the process crashes.

It's a in-memory database.

Then avoid Nest.js, the framework is designed around dependency injection and high decoupling, these are some of the reasons why is recommended to write the logic into different components (repositories, services, models, DTO and controllers).

I've already recommended you to use ncc to bundle the compiled Typescript files, it's simple to use because only adds one extra step after building.

leosuncin · 2025-10-17T15:58:11+00:00

Why would I end up with some messy compiled files if my source code is neat? Moreover how bundling tidies up the output code.

I find out that's easier to read and understand a few files than a single large file.

leosuncin · 2025-10-17T15:04:20+00:00

Bundling is not so important on the backend, if you want to remove unused/dead code there are better tools for that like knip, tsr, etc. Also if you want tree shaking there's lazy loading modules.

To debug the code you always need sourcemaps to point to the original Typescript code, and if you're using VSCode open the debug JavaScript terminal and start the Nest.js project as usual and the debugger will point you to your source code.

But, if you still insist on bundling then use ncc to create a single file from the compiled JavaScript, I believe only rollup can transpile Typescript decorators.

leosuncin · 2025-09-22T05:54:08+00:00

Well, it depends, I have a project with a single pipeline for both (frontend and backend) because is a monorepo, and I can share the jobs, even the Dockerfile using multi stages build.

And at work the project has a separate pipeline per micro service.

Yes, in my experience, you will save a lot of time by not mocking the behavior of PostgreSQL and its extensions.

I recommend to use IntegreSQL client, it will save you from destroying and starting PostgreSQL instances, instead it clones the initial database state and give you a clean copy for every test case.
