@dev.fast/diffr

TypeScript types, zod validators, and a binary fetcher for diffr's NDJSON protocol. The package version matches the diffr release.

import { decodeStructuralDiffEvent } from "@dev.fast/diffr";
const event = decodeStructuralDiffEvent(line);

npx --package @dev.fast/[email protected] diffr-fetch --into ./bin --required

Supports macOS arm64, macOS x64, Linux arm64, and Linux x64. --check verifies an existing install without network access. Downloads warn on network failure unless --required; invalid hashes or archives always fail.

Wire changes

Keep these files in sync:

| Files (from repo root) | Check | |---|---| | src/protocol/mod.rs, src/pairing.rs, diffr-ts/src/contract.ts | Contract tests against the binary; Rust version check | | docs/streaming.md | Review against the wire format | | tui/packages/hunk/src/diffr/wire.ts (v3 only) | TUI fixture tests | | Review's packages/review-protocol/package.json and packages/review/package.json | Exact package version pins |

Release

After tagging the matching Rust release and building with cargo build --locked, run from diffr-ts. New pins select the CLI-only release archives; older pins continue to use the full archives:

bun install --frozen-lockfile
npm run pin
bun run typecheck && bun test
npm publish --access public
