Resolving Class constructor error
Hello, I am currently trying to port a small test api from NodeJS to Deno.
This code uses only NPM packages and is a direct copy past from the previous project besides the "npm:" addition to packages.
Currently when running the code, there are no errors on compile, only during run time when trying to create the postgress client, which seems to come from the postgress library. I have not been succesful in finding a solution either here in discord or online. Only semi relevant would be changing the compile target which I also tried but got the following error
This was using the example compiler options from https://deno.land/manual@v1.36.4/advanced/typescript/configuration
Attached is the code as in the main.ts file, along with the error produced when calling the function. Thank you

Edit: While there is a deno port of drizzle it is no longer up to date. And the Postgres deno library is not compatible with the npm drizzle library.

Based on the documentation, it seems like you're trying to use an npm package directly in Deno, which might not work as expected due to differences in the runtime environments of Node.js and Deno.
Deno has its own way of handling database connections, and it provides a Postgres client that you can use. Here's an example of how to connect to a Postgres database using Deno:
You can then execute SQL queries like this:
And don't forget to close the connection when you're done:
To run this example, you would use the Deno CLI like this:
Please note that the
--allow-net
and --allow-env
flags are necessary to allow network access and access to environment variables, respectively.
As for the TypeScript configuration, Deno has its own TypeScript runtime and does not use tsconfig.json
. The target
and lib
options are set by Deno and cannot be changed. If you need to use a specific TypeScript configuration for your project, you might need to compile your TypeScript code to JavaScript first, and then run the JavaScript code with Deno.
If you're still having issues, it would be helpful to know more about the specific error message you're encountering. The error message you provided seems to suggest that there's an issue with the way the Socket
class is being used, but without more context, it's hardto provide a specific solution.
