@eslint/compat is an ESLint plugin designed to ensure code compatibility across different JavaScript environments. It leverages ESLint's linting capabilities to identify and flag potentially problematic syntax or features unsupported by targeted browsers or Node.js versions. By configuring specific target environments, developers can proactively address compatibility issues during development, leading to more robust and universally accessible JavaScript code. This plugin helps maintain consistency and avoid unexpected runtime errors due to browser or environment-specific limitations.
@eslint/compat releases varied over the past year. There were bursts in May and October 2024, and January and June 2025. No releases occurred in August, September 2024 and March and July 2025. The most recent versions, 1.3.0 and 1.3.1, were released in June 2025.
@eslint/compat downloads show a strong upward trend from May 2024 to July 2025, peaking at over 12 million. August 2025 downloads are significantly lower, around 6 million, but the month is incomplete, so further increases might be observed until the end of the month.
