"npm run build" does not build a new file I added

Hi, I added a new .js file under the /src folder and imported some variables from this file. However, when I typed "npm run build", this file has not been added to the lib. Is this because parse server maintains a file index list and I have to add my file to this list? Thanks

I created a dummy.js file and npm run build generated a dummy.js file under lib folder. you can delete the exisiting lib folder first and run npm run build again to see if it solves the problem.
