@fueled/eslint-config-fueled-node v1.2.0
TypeScript ESLint rules for Node applications
This configuration focuses specifically on code quality based rules for TypeScript, rather than formatting rules. We utilize Prettier for code formatting (see prettier-config-fueled-node).
Note: this is intended to be used with TypeScript strict mode enabled, and Prettier installed.

Rules
ESLint rules extend upon @typescript-eslint/recommended, as well as Prettier ESLint config to turn off rules that may conflict with Prettier. Overriding rules are listed below.
@typescript-eslint/array-type Enforce T[] syntax for arrays over Array.
@typescript-eslint/explicit-function-return-type Enforce explicit function return types.
@typescript-eslint/explicit-module-boundary-types Enforce explicit return & argument types on exported functions & public class methods.
@typescript-eslint/no-explicit-any Disallow explicit
anytypes. Useunknowninstead.@typescript-eslint/no-floating-promises Require Promise-like statements to be handled appropriately.
@typescript-eslint/no-non-null-assertion Disable using non-null assertions as they cancel the benefits of strict null-checking mode. Prefer explicit null checks for safety.
no-restricted-syntax Restrict use of labels and with statements.
@typescript-eslint/no-unnecessary-condition Avoid unnecessary conditionals.
@typescript-eslint/no-unnecessary-type-assertion Warn against unnecessary type assertions.
@typescript-eslint/no-unused-vars Enforce no unused variables.
@typescript-eslint/no-useless-constructor Warn against useless class constructors.
@typescript-eslint/prefer-nullish-coalescing Prefer nullish coalescing operator.
@typescript-eslint/prefer-optional-chain Prefer optional chaining operator.
@typescript-eslint/restrict-template-expressions Restrict template expressions to allow for string & number types only. Other types must be checked explicitly.
@typescript-eslint/require-await Disallow async functions which have no await expression and do not return a promise.
@typescript-eslint/switch-exhaustiveness-check Enforce covering all cases in a switch statement.
