# ADR-001: Deno-first, JSR publishes, npm comes free

## Status

Accepted

## Context

The package needs to be usable from both Deno and Node.js. Maintaining separate build pipelines (dnt, esbuild) is overhead. JSR automatically provides npm compatibility via `@jsr/alkdev__storage`.

## Decision

Publish to JSR (`deno publish`). npm compatibility is automatic via JSR's npm layer. No separate dnt build step.

## Consequences

- Source files use `.ts` extension with explicit import paths (Deno convention)
- `--allow-slow-types` is used on publish; `"exclude": ["no-slow-types"]` in lint config
- npm consumers install `@jsr/alkdev__storage`
- No dual-publishing pipeline to maintain
