ESLint v10.2.0 released
Eslint ships v10.2.0 with language-aware rules via meta.languages, letting rule authors declare supported languages and triggering runtime errors on unsupported ones. It also adds Temporal support, updates globals, and fixes several bugs.
We just pushed ESLint v10.2.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.
Highlights
Language-aware rules
ESLint v10.2.0 adds support for language-aware rules through the new meta.languages property. Rule authors can now explicitly declare which languages a rule supports, and ESLint will throw a runtime error if that rule is enabled for an unsupported language, as specified by the language configuration option.
Here is an example of a rule that only supports the JavaScript language:
const rule = { meta: { type: "problem", docs: { description: "Example JavaScript rule", }, languages: ["js/js"], }, create(context) { return {}; }, };Currently, none of the ESLint built-in rules restrict the languages they are designed to work with, but this may change in the future.
More information about the meta.languages property can be found in the custom rules documentation.
Temporal support
With the Temporal proposal now at TC39 stage 4, ESLint v10.2.0 recognizes Temporal as a built-in global. As a result, the no-undef rule no longer flags Temporal under the default configuration:
/* eslint no-undef: "error" */ const now = Temporal.Now.instant(); // OKIn addition, the no-obj-calls rule now reports direct calls to the global Temporal object:
/* eslint no-obj-calls: "error" */ Temporal(); // Error: 'Temporal' is not a function.Features
