My current setup involves using ts-node with express in production and so far, it's been functioning smoothly. Am I missing out on any benefits by not compiling and running .js files instead?

As per the insights provided by Blake Embrey, the creator of ts-node, it is advised to utilize it for production purposes, but ensure to incorporate the --transpile-only flag.
For instance:
ts-node --transpile-only ./src/start.ts
If you opt for transpiling only, it will result in reduced memory usage since no type information is generated. Nevertheless, issues may arise when utilizing reflect-metadata (with experimental decorator support).
To sum up: Utilize ts-node --transpile-only (there's also ts-node-transpile-only) for production unless you are working with reflect-metadata. In such cases, resort to using tsc in conjunction with the conventional node.
Avoid using it in production as it may slow down the startup time and consume more memory due to keeping the compiler and files in memory for caching purposes.
Instead, it is recommended to precompile the files using your build tools to ensure that the builds are successful. This helps prevent any discrepancies between development and production environments.
In some cases, you may want to halt deployment if the application fails to build properly before attempting to run it. For example:
yarn
yarn compile // tsc index.ts (should return 0 to continue)
yarn start // node index.js
When creating your server, consider using a dockerfile and for development purposes, use a combination of tsc + nodemon.
