From 81e810ec9a4c78ee1010bb99e1d9491c7605bdcd Mon Sep 17 00:00:00 2001 From: Xi Xu Date: Mon, 8 Dec 2025 19:57:48 +0800 Subject: [PATCH] Add type declarations and improve test typings Introduces src/types.d.ts and test/types.d.ts for Cloudflare Workers and test utilities. Enhances JSDoc comments and type annotations across test files for better type safety and clarity. Updates tsconfig.json to use bundler module resolution and include additional type sources. Minor test logic and assertion improvements for robustness. --- src/types.d.ts | 20 +++++++ test/benchmark/performance.bench.js | 4 +- test/features/performance.test.js | 9 +++- test/features/range-cache.test.js | 1 + test/features/security.test.js | 82 +++++++++++++++-------------- test/fixtures/responses.js | 2 + test/helpers/assertions.js | 4 +- test/helpers/index.js | 7 +-- test/helpers/mocks.js | 8 +-- test/index.test.js | 3 +- test/integration.test.js | 2 +- test/platforms/cran.test.js | 2 +- test/platforms/opensuse.test.js | 2 +- test/setup.js | 2 + test/types.d.ts | 24 +++++++++ test/unit/utils.test.js | 23 ++++++++ tsconfig.json | 7 ++- 17 files changed, 143 insertions(+), 59 deletions(-) create mode 100644 src/types.d.ts create mode 100644 test/types.d.ts diff --git a/src/types.d.ts b/src/types.d.ts new file mode 100644 index 0000000..4c5676f --- /dev/null +++ b/src/types.d.ts @@ -0,0 +1,20 @@ +/** + * Global type declarations for Cloudflare Workers + */ + +/** + * Cloudflare Workers execution context + * Provides methods for managing background tasks + */ +interface ExecutionContext { + /** + * Extend the lifetime of the request handler + * @param promise - Promise to wait for in the background + */ + waitUntil(promise: Promise): void;
