💡 What:
Refactored
fs.readFileSync(path).toString()calls tofs.readFileSync(path, 'utf8')in the following packages:@expo/cli@expo/config-pluginsexpo-brownfieldpod-install🎯 Why:
When reading files in Node.js, omitting the encoding argument causes
fs.readFileSyncto allocate an intermediateBufferobject which then has to be explicitly converted into a string using.toString(). By passing'utf8'directly tofs.readFileSync, Node.js skips the intermediate Buffer allocation and decodes the stream directly into a string, slightly improving both memory efficiency and CPU time.📊 Impact:
Reduces transient memory allocations and Garbage Collection (GC) overhead during file parsing and CLI operations (like generating git ignores or applying config plugins). It also makes the code slightly more concise and readable.
🔬 Measurement:
The core functionality remains identical as the default decoding algorithm is exactly the same. Verified that all linter rules and tests (
yarn test) continue to pass smoothly on the affected packages.PR created automatically by Jules for task 1996556486635509377 started by @vishnu-madhavan-git
