Currently we have linter rules defined both in tsconfig.json, handled by the typescript compiler AND linter rules defined in the eslint config, handled by eslint.

The typescript linter rules are really annoying devex, as they prevent building and experimenting with working code because of linter errors.

Describe the solution you'd like

  • Replace all typescript linter rules with eslint linter rules

Additional context

aegir/src/config/tsconfig.aegir.json

Lines 24 to 28 in 72d2fcd

// linter checks
"noImplicitReturns": false,
"noFallthroughCasesInSwitch": true,
"noUnusedLocals": true,
"noUnusedParameters": false,

fix: use @typescript-eslint/no-unused-vars (#221)
9a95776 
- See ipfs/aegir#1459

Aegir currently relies on typescript to perform two linter rules, which is annoying for reasons mentioned in the above issue.
- `noFallthroughCasesInSwitch`
- `noUnusedLocals`

This PR makes typescript rules more strict to enforce both of these conditions.

For `noFallthroughCasesInSwitch`, it appears that the `standard` eslint rule set [already includes](https://github.com/standard/eslint-config-standard/blob/master/src/index.ts#L143) the [`no-fallthrough`](https://eslint.org/docs/latest/rules/no-fallthrough) rule.
So this PR only needs to enforce `noUnusedLocal`, and we just add [`@typescript-eslint/no-unused-vars`](https://typescript-eslint.io/rules/no-unused-vars/).
