Worked on the PostHog/posthog-js repository to enhance reliability and maintain compliance within the Nuxt integration. Addressed a bug by ensuring the Nuxt module skips server-side sourcemap injection when running in SPA mode with SSR disabled, adding regression tests to verify client-only builds and prevent sourcemap upload failures. Updated package.json licensing metadata to a valid SPDX expression, aligning with automated license tooling and avoiding parsing errors. Focused on code quality by refining ESLint rules and updating tests for Nuxt-specific requirements. Utilized JavaScript, TypeScript, and JSON, emphasizing maintainability, traceability, and adherence to best practices in package management and testing.
