From 1660ae22919b8fa90472c73655f92494179436e9 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 22 Apr 2026 13:11:52 +0000 Subject: [PATCH 1/6] feat: add Bun runtime support Bun's TypeScript loader does not automatically elide type-only re-exports the way ts-node does, so `export { CustomResponse }` from `src/index.ts` threw a SyntaxError ("export 'CustomResponse' not found"). Mark it as a type-only re-export so both runtimes can load the module. Adds a `test:bun` npm script that runs the existing mocha suite under Bun's runtime, plus a `Test on Bun` job in the check workflow so Bun coverage runs on every PR and release. https://claude.ai/code/session_01PE9wGrZ1wb7Nuq9czWjJz4 --- .github/workflows/check.yaml | 28 ++++++++++++++++++++++++++++ package.json | 1 + src/index.ts | 2 +- test/README.md | 9 +++++++++ 4 files changed, 39 insertions(+), 1 deletion(-) diff --git a/.github/workflows/check.yaml b/.github/workflows/check.yaml index d35e6327..7d0996c5 100644 --- a/.github/workflows/check.yaml +++ b/.github/workflows/check.yaml @@ -38,3 +38,31 @@ jobs: - name: Run Tests run: npm test + + bun_test: + name: Test on Bun + if: ${{ !contains(github.event.head_commit.message, '[skip ci]') }} + runs-on: ubuntu-22.04 + + steps: + - name: Checkout repository + uses: actions/checkout@v6 + + - name: Use Node.js 18 + uses: actions/setup-node@v6 + with: + node-version: 18 + + - name: Install Bun + uses: oven-sh/setup-bun@v2 + with: + bun-version: latest + + - name: Install Dependencies + run: npm install + + - name: Add localhost-test to Linux hosts file + run: sudo echo "127.0.0.1 localhost-test" | sudo tee -a /etc/hosts + + - name: Run Tests with Bun + run: npm run test:bun diff --git a/package.json b/package.json index 1c0b4485..e3bf3c0d 100644 --- a/package.json +++ b/package.json @@ -38,6 +38,7 @@ "prepublishOnly": "npm run build", "local-proxy": "node ./dist/run_locally.js", "test": "nyc cross-env NODE_OPTIONS=--insecure-http-parser mocha", + "test:bun": "bun --bun run mocha", "test:docker": "docker build --tag proxy-chain-tests --file test/Dockerfile . && docker run --add-host localhost-test:127.0.0.1 proxy-chain-tests", "test:docker:all": "bash scripts/test-docker-all.sh", "lint": "eslint .", diff --git a/src/index.ts b/src/index.ts index f945ef87..998aa7fa 100644 --- a/src/index.ts +++ b/src/index.ts @@ -4,4 +4,4 @@ export * from './utils/redact_url'; export * from './anonymize_proxy'; export * from './tcp_tunnel_tools'; -export { CustomResponse } from './custom_response'; +export type { CustomResponse } from './custom_response'; diff --git a/test/README.md b/test/README.md index 99c1bead..c432b3c9 100644 --- a/test/README.md +++ b/test/README.md @@ -58,3 +58,12 @@ Note: for test in Docker no changes in `/etc/hosts` needed. ```bash npm run test test/anonymize_proxy.js ``` + +### Run tests with Bun + +[Bun](https://bun.com) is supported as an alternative runtime.

The e2e tests exercise HTTP/1.1 pipelining through ProxyChain.Server and util.promisify(stream.pipeline) over upstream HTTP responses; both have known runtime gaps in Bun 1.3 that cause individual tests to hang on their per-test mocha timeout, compounding into the job timeout.

They exercise createTunnel's error paths through chai+mocha without binding sockets, opening upstream HTTP, or otherwise touching the Bun runtime gaps.
