## Summary PR https://github.com/facebook/react/pull/31963 migrated the bundler from Rollup to esbuild, but the `react-compiler-healthcheck` script lacks a shebang, leading to issues with `npx` not being able to execute it. https://github.com/facebook/react/blob/dc7578290f1bc55c358bee3a7eeb5e5f4551adfd/compiler/packages/react-compiler-healthcheck/rollup.config.js#L60-L78 https://github.com/facebook/react/blob/9eabb37338e6bea18441dec58a4284fe00ee09ae/compiler/packages/react-compiler-healthcheck/scripts/build.js#L38-L53 ## How did you test this change? **Before** (fail) ```shell (main)> npx --version 10.5.0 (main)> npx react-compiler-healthcheck /home/jeremy/.npm/_npx/67b118a83a29962c/node_modules/.bin/react-compiler-healthcheck: line 1: /bin: Is a directory /home/jeremy/.npm/_npx/67b118a83a29962c/node_modules/.bin/react-compiler-healthcheck: line 2: syntax error near unexpected token `(' /home/jeremy/.npm/_npx/67b118a83a29962c/node_modules/.bin/react-compiler-healthcheck: line 2: ` * Copyright (c) Meta Platforms, Inc. and affiliates.' ``` **After** ```shell (main)> npx react-compiler-healthcheck Successfully compiled 108 out of 146 components. StrictMode usage not found. Found no usage of incompatible libraries. ```
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
