[WIP] Refactor to Typescript

[paustint]

TODO:

Code is not yet working, there is some sort of error that happens and the program exits with error code 2. the global excelize object is never being set with properties, so it is failing before this

This also shows up in the logs panic: syscall/js: call of Value.Get on undefined

Also, Reflect.x appear to be invalid usage. Accord to type definitions the first parameter requires a function, but non-function values are being passed in. This should be reviewed and corrected.

Temporary items that will be cleaned up

• I have temporarily added in some logging statements that will be removed once the PR is ready for review
• Removed terser and added source maps to allow local debugging, this will also be fixed
• Delete original index.js - I left this for reference while confirming everything is 100% working

To test the code, run npm install to install new dependencies, then run npm run build to build the JS and GO

Example of what is still failing

Description

This is a 100% refactor that was generally a copy/paste of the initial codebase, but converted to Typescript and cleaned up the codebase a bit to make it easier to read and maintain.

Motivation and Context

This is a 100% refactor that was generally a copy/paste of the initial codebase, but converted to Typescript and cleaned up the codebase a bit to make it easier to read and maintain.

The codebase was using a mixture of very legacy javascript and modern javascript.

Prettier has also been added to ensure code formatting remains consistent across contributors.

How Has This Been Tested

TODO: still testing.

Was unable to get this to work, going to close this PR and open a new one with just a few changes.
