All the problems I found by a quick look around

[TymanWasTaken]

1. You don't define the types of way too many things, mostly function parameters
2. You have the tsc settings to ignore implicit any and this, not very good practice
3. Please use consistent capitalization please (ClassName, variableName, FileName.ts)
4. You have way too many anys (1 is too many) please use unknown if you really really need to
5. Not really an issue but use https://npmjs.org/package/source-map-support
6. Some random files use .markdown file extension what
7. Those files also aren't in caps and thats weird
8. Missing a workflow
9. Add dependabot
10. You appear to disable a bunch of types at the top of files which is not good, use // eslint-disable-next-line if you really really need to, though you shouldn't be disabling those checks anyway
