Introduction For TypeScript files with the .ts extension, we cannot run them directly. We need to transpile TypeScript to JavaScript and then run the JavaScript output. There are two common approaches: upload .ts to the server and compile via CI, or transpile locally and upload the .js build to production. If you want to run and test locally during development, you can use ts-node, but the project still needs a build step for production.
