Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rolldown-zarara) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rolldown-zarara

Node.js bindings for the acyclic_output_fuzz Rust crate. Generates synthetic ES-module fixtures (modules + rolldown.config.js) intended to surface circular-reference outputs from the rolldown bundler.

Prerequisites

The underlying crate depends on rolldown via a git submodule. From the workspace root:

git submodule update --init --recursive

Build

From the workspace root:

pnpm install
pnpm build:dev       # fast, unoptimized — good for iteration
pnpm build:release   # optimized + LTO — slow to compile, fast at runtime

pnpm build is an alias for pnpm build:release.

Either command produces a platform-specific .node addon plus the generated index.js and index.d.ts.

Usage

const {
  generateFixtureFromSeed,
  generateFixtureFromCaseSpec,
} = require('rolldown-zarara')

// Random graph from a u64 seed.
const dir1 = generateFixtureFromSeed(42n)
console.log(dir1)

// Optional explicit output directory.
const dir2 = generateFixtureFromSeed(42n, '/tmp/my-fixture')

// Deterministic graph from a case spec string.
const spec = 'n=3;e=0;c=none;s=0-1,1-2;d=none;r=none;x=none;p=0;o=0;t=0;m=1'
const dir3 = generateFixtureFromCaseSpec(1n, spec)

Each call writes rolldown.config.js plus node*.{js,cjs} files into the returned directory.

A runnable example lives at examples/generate.mjs:

pnpm --filter rolldown-zarara example

API

function generateFixtureFromSeed(
  seed: bigint,
  outputDir?: string | null,
): string

function generateFixtureFromCaseSpec(
  seed: bigint,
  caseSpec: string,
  outputDir?: string | null,
): string

Publishing

CI publishes to npm via .github/workflows/napi-publish.yml. Two triggers:

Tag push — push a tag like napi-v0.1.0.
Manual — run the workflow from the GitHub UI ("Run workflow").

The workflow builds the binary on five targets in a matrix (x86_64-apple-darwin, aarch64-apple-darwin, x86_64-unknown-linux-gnu, aarch64-unknown-linux-gnu, x86_64-pc-windows-msvc), collects the .node artifacts into napi/npm/<triple>/, and runs npm publish on the main package plus each per-platform sub-package.

One-time setup

Create an automation token at npmjs.com and add it as a repository secret named NPM_TOKEN. The workflow reads it through ${{ secrets.NPM_TOKEN }}.

Cutting a release

From the repo root, bump every package in lockstep:
```
pnpm bump 0.1.1
```
This rewrites napi/package.json and each napi/npm/<triple>/package.json so they share the same version.

Commit and tag:

git commit -am "napi: v0.1.1"
git tag napi-v0.1.1
git push --follow-tags

Watch the napi-publish workflow run; check npm for the new versions.

Adding or removing a target

Edit the matrix in .github/workflows/napi-publish.yml and the napi.triples.additional list in napi/package.json. For new triples, also create napi/npm/<triple>/package.json mirroring the existing files.
