Deploy on heroku v2

[EshwarCVS]

In the current code, we are facing an issue while executing the command: deno run --allow-net --allow-read server.js

They were caused by #6653. A version of std before 0.61.0 is incompatible with Deno 1.2.0. deno info main.ts will give you the dependency graph, and you can determine what dependencies need to be updated to they are using std 0.61.0. Check out the URL

I have updated the versions. This version will be user ready to fork and improve the code.
