Sane Code

Run npx sane-code in your repo to check for things like

JSON Schema validity of your package.json, .eslintrc.js etc
unnecessary defaults in config files like tsconfig.json or package.json
subjective code smells like @types/* in dependencies instead of devDependencies
whether or not linting is set up
if there's only one type of lockfile present
whether or not the project depends on deprecated packages
best practices like no hard-pins of dependencies, test script set up
recommendations like enabling esModuleInterop in tsconfig.json etc
unused TypeScript exports
unused TypeScript symbols

Feel free to open issues if you have suggestions for more checks ☺️
