How to go ahead with NodeJS Helper Library Publishing?

• Will use NPM Registry rather than GH Registry
• Will be using this repo for initial development.
• With a initial feature ready build, will move the code to a separate repo - logsmith.js
• Will Develop logsmith.js as a standalone logging library with support for monitor
• Will publish/release on separate GH Repo

[Publishing to GH Registry]

[TanmoySG]

• Published to GH Registry - has some issues if I try to install it locally
  

• Needs to set proxy and all that. Which is an added step just to get the package.

Will publish to NPM Registry - less steps to follow for end user.

        const logStatement = format(
            template,
             {

Save logs in file on exit only. Read Logs and write logs to Program Variables and not to file.
