Linting SVG in JSX with ESLint
An ESLint plugin can catch missing SVG accessibility attributes and common quality issues directly in your editor as you write JSX.

Catching SVG Accessibility Issues During Development
An ESLint plugin with SVG-aware or JSX-a11y rules can flag an inline SVG icon button missing an aria-label, a decorative SVG missing aria-hidden, or other common accessibility oversights directly in the editor as code is written, catching issues far earlier than a manual accessibility audit after the feature ships.
- Flags missing aria-label on interactive SVG icon buttons automatically
- Catches decorative SVGs missing aria-hidden during development itself
- Provides feedback in-editor rather than only during a later manual audit
Enforcing Consistent SVG Code Quality Standards
Beyond accessibility, custom or existing ESLint rules can enforce project conventions like requiring currentColor instead of hardcoded fill values, flagging overly large inline SVG path data that should be extracted to a separate file, or catching duplicate SVG id attributes that could collide when multiple icons render on the same page.

Frequently Asked Questions
Does linting SVG in JSX require a special plugin, or does standard ESLint cover it?
SVG-specific and accessibility-focused checks generally require a dedicated plugin (like eslint-plugin-jsx-a11y for accessibility rules), since standard ESLint's built-in rules don't specifically understand SVG accessibility semantics.
Can these lint rules be enforced automatically in CI, not just locally?
Yes, running the same ESLint configuration as a CI check ensures the rules are enforced consistently for every contributor, not just those who have the plugin configured locally in their own editor.
