--- description: 'Disallow member access on a value with type `any`.' --- > 🛑 This file is source code, not the primary documentation location! 🛑 > > See **https://typescript-eslint.io/rules/no-unsafe-member-access** for documentation. Despite your best intentions, the `any` type can sometimes leak into your codebase. Member access on `any` typed variables is not checked at all by TypeScript, so it creates a potential safety hole, and source of bugs in your codebase. ## Rule Details This rule disallows member access on any variable that is typed as `any`. Examples of code for this rule: ### ❌ Incorrect ```ts declare const anyVar: any; declare const nestedAny: { prop: any }; anyVar.a; anyVar.a.b; anyVar['a']; anyVar['a']['b']; nestedAny.prop.a; nestedAny.prop['a']; const key = 'a'; nestedAny.prop[key]; // Using an any to access a member is unsafe const arr = [1, 2, 3]; arr[anyVar]; nestedAny[anyVar]; ``` ### ✅ Correct ```ts declare const properlyTyped: { prop: { a: string } }; properlyTyped.prop.a; properlyTyped.prop['a']; const key = 'a'; properlyTyped.prop[key]; const arr = [1, 2, 3]; arr[1]; const idx = 1; arr[idx]; arr[idx++]; ``` ## Options ```jsonc // .eslintrc.json { "rules": { "@typescript-eslint/no-unsafe-member-access": "error" } } ``` This rule is not configurable. ## Related To - [`no-explicit-any`](./no-explicit-any.md)
