Make the compiler config honestly describe a Node 22 / Bun 1.1+ / Deno library:
target ES2020 -> ES2023, lib [DOM, ESNext, DOM.Asynciterable] -> [ES2023], drop
the now-inert downlevelIteration. 8.0 dropped the browser path, so the DOM lib
was misleading (it implied web APIs the package no longer supports). No
ES2021-2023 syntax is used anywhere, so .js emit is effectively unchanged — this
is hygiene, not a perf/behavior change.
The one real consequence of dropping DOM: the Cloudflare-Workers edge probe read
globalThis.caches from the DOM lib — declared `caches?: unknown` locally on the
runtime-globals intersection alongside Deno/Bun/HTMLRewriter.
.d.ts is shape-stable (TS-5.x-parseable preserved — no cor coordination). Gates:
typecheck 0, cli-tsconfig 0, typecheck-tsconfig (the .d.ts contract surface) 0,
build 0, test:unit 1753/1753, test:bun 8/8.
Consumer-invisible modernization pass — no public API or runtime-behavior
change; dist for the override-only files is byte-identical.
Toolchain:
- CI: GitHub Actions matrix — Node 22/24 (test:unit) + Bun latest (test:bun).
- engines: node ">=22" (was "22.x"), bun ">=1.1.0".
- tsconfig: isolatedModules + noImplicitOverride; add the 33 `override`
modifiers the flag requires across storage/integrations/vfs/transaction.
- deps: @types/node ^22; add prettier; drop dead standard-version,
@rollup/plugin-* and the redundant embedded eslintConfig (flat
eslint.config.js is the active config — verified identical lint output).
paramValidation: replace the top-level `await import('node:os'/'node:fs')`
with static ESM imports. The top-level-await form poisoned the module graph;
static imports also drop the browser/edge fallback branches no supported
runtime reaches (8.0 is Node/Bun/Deno-only).
Bun positioning: recommend Bun as a runtime (`bun add` / `bun run`), which is
green (test:bun 8/8). Drop single-binary `bun build --compile` as a target —
native addons cannot embed into it, and Bun 1.3.10 has a `--compile` codegen
regression around top-level await. Rename the Bun test to bun-runtime-test.ts
and correct docs that overclaimed single-binary support.
Gates: typecheck 0, build 0, test:unit 1743/1743, test:bun 8/8.
