@grafana/eslint-plugin

Custom ESLint rules. Source under packages/grafana-eslint-rules/.

The package is published as @grafana/eslint-plugin (note the rename) and consumed by the root eslint.config.js plus by external plugin authors who want to enforce Grafana's conventions.

Notable rules

Rule	Enforces
theme-token-usage	All colors must come from theme tokens, not raw literals
no-untranslated-strings	User-visible strings must be wrapped in <Trans> / t()
no-restricted-img-srcs	Images must come from approved hosts
import-order	A Grafana-specific import/order config
Accessibility helpers	Catches missing aria-* on interactive elements

The rules are written in TypeScript using the @typescript-eslint/utils AST API. New rules are added when a class of bug is found often enough to warrant automation.

Suppressions file

The repo has an eslint-suppressions.json (>100 KB) — a baseline of pre-existing violations that newer code is expected to avoid. New violations fail CI. The list is whittled down over time via yarn lint:prune.
