From e4a12c3a879d3cdaa048e41356a03e97bccb791e Mon Sep 17 00:00:00 2001 From: Claude Code Date: Wed, 19 Nov 2025 14:28:36 -0800 Subject: [PATCH 01/37] feat: add decompress option support with Fastly decompressGzip mapping (#81) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement cross-platform decompression control by mapping the @adobe/fetch decompress option to platform-specific behavior: - Fastly: Maps decompress to fastly.decompressGzip - Cloudflare: Pass-through (auto-decompresses) - Node.js: Pass-through to @adobe/fetch The wrapper accepts decompress: true|false (default: true) and automatically sets fastly.decompressGzip when running on Fastly Compute. Explicit fastly options take precedence over the mapped value. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Signed-off-by: Lars Trieloff --- src/template/polyfills/fetch.js | 58 +++++++++-- test/fetch-polyfill.test.js | 176 ++++++++++++++++++++++++++++++++ 2 files changed, 228 insertions(+), 6 deletions(-) create mode 100644 test/fetch-polyfill.test.js diff --git a/src/template/polyfills/fetch.js b/src/template/polyfills/fetch.js index cad34f8..5ea6a2d 100644 --- a/src/template/polyfills/fetch.js +++ b/src/template/polyfills/fetch.js @@ -11,10 +11,56 @@ */ /* eslint-env serviceworker */ -module.exports = { - // replacing @adobe/fetch with the built-in APIs - fetch, - Request, - Response, - Headers, +/** + * Detects if the code is running in a Cloudflare Workers environment. + * @returns {boolean} true if running on Cloudflare + */ +function isCloudflareEnvironment() { + try { + // caches is a Cloudflare-specific global (CacheStorage API) + return typeof caches !== 'undefined' && caches.default !== undefined; + } catch { + return false; + } +} + +/** + * Wrapper for fetch that provides cross-platform decompression support. + * Maps the @adobe/fetch `decompress` option to platform-specific behavior: + * - Fastly: Sets fastly.decompressGzip based on decompress value + * - Cloudflare: No-op (automatically decompresses) + * - Node.js: Pass through to @adobe/fetch (handles it natively) + * + * @param {RequestInfo} resource - URL or Request object + * @param {RequestInit & {decompress?: boolean, fastly?: object}} options - Fetch options + * @returns {Promise} The fetch response + */ +function wrappedFetch(resource, options = {}) { + // Extract decompress option (default: true to match @adobe/fetch behavior) + const { decompress = true, fastly, ...otherOptions } = options; + + // On Cloudflare: pass through as-is (auto-decompresses) + if (isCloudflareEnvironment()) { + return fetch(resource, options); + } + + // On Fastly/Node.js: map decompress to fastly.decompressGzip + // This will be used on Fastly and ignored on Node.js + const fastlyOptions = { + decompressGzip: decompress, + ...fastly, // explicit fastly options override + }; + return fetch(resource, { ...otherOptions, fastly: fastlyOptions }); +} + +// Export wrapped fetch and native Web APIs +export { wrappedFetch as fetch }; +export const { Request, Response, Headers } = globalThis; + +// Export for CommonJS (for compatibility with require() in bundled code) +export default { + fetch: wrappedFetch, + Request: globalThis.Request, + Response: globalThis.Response, + Headers: globalThis.Headers, }; diff --git a/test/fetch-polyfill.test.js b/test/fetch-polyfill.test.js new file mode 100644 index 0000000..46e7a9f --- /dev/null +++ b/test/fetch-polyfill.test.js @@ -0,0 +1,176 @@ +/* + * Copyright 2024 Adobe.

charset=UTF-8 Content-Transfer-Encoding: 8bit Platform detection was incorrectly identifying Fastly Compute@Edge as Cloudflare when both platforms had a caches object. This caused: - Backend and cacheKey options to be stripped on Fastly - decompress option not being mapped to fastly.decompressGzip Changed the detection logic to check isFastly flag first before checking for caches.default, ensuring Fastly is correctly identified. This fixes the JSON parse errors in decompress tests and 503 errors in CacheOverride tests on Fastly Compute@Edge. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Signed-off-by: Lars Trieloff --- src/template/polyfills/fetch.js | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/template/polyfills/fetch.js b/src/template/polyfills/fetch.js index cee3aa4..a9b8de8 100644 --- a/src/template/polyfills/fetch.js +++ b/src/template/polyfills/fetch.js @@ -189,7 +189,8 @@ const { */ async function wrappedFetch(resource, options = {}) { // Check for Cloudflare dynamically (for testability) - const isInCloudflare = typeof caches !== 'undefined' && caches.default !== undefined; + // Prioritize Fastly detection - if we successfully loaded fastly:cache-override, we're on Fastly + const isInCloudflare = !isFastly && typeof caches !== 'undefined' && caches.default !== undefined; // On Cloudflare, strip out Fastly-specific options that aren't supported const { cacheOverride, ...restOptions } = options;
