May 1, 2025

2025-05 monthly summary for the supabase/supabase-js repository. Focus in this period was on architecture alignment and dependency tooling. Key delivery: Deno tooling migration by removing deno.lock and shifting away from Deno as the primary runtime/build tool, establishing groundwork for a new runtime/tooling strategy. No major bug fixes were closed this month. Overall impact: simplifies the build pipeline, reduces dependency management complexity, and clarifies the runtime strategy to enable future tooling improvements. Technologies/skills demonstrated: JavaScript/TypeScript, build tooling considerations, dependency management, and migration planning.
