npm run dev not working in Codespaces

[AnadyaNair]

Does codespace host files locally? When attempting to use npm run dev in a Codespaces environment, the command fails to execute as expected. This behaviour is inconsistent with typical npm behaviour and appears to be specific to the Codespaces environment. The codespace gives an output message in the terminal that the project is hosted at localhost, but there seems to be an issue with that.

Steps to Reproduce:

1. Open a Codespaces environment with a Node.js project.
2. In the terminal, run the command npm run dev.

Expected Behavior: The npm run dev command should execute and start the development server as specified in the project's package.json file.

Actual Behavior:

npm start will start the dev server 👍
