I'm a nobody in g0v and a student of Taigi. I'm using itaigi a lot and would like to give back.
This PR is part of a series of changes I'd like to contribute to clean up the itaigi codebase.
1. Bumps node version from the current version (5) to the latest version (15).
2. Adds eslint as a dependency
3. Starts cleaning up the code as per eslint.
