Verified usage

Verified import paths — ran on the pinned version, not inferred.

reactExterns

✓ // No import needed; run closure-compiler with --externs node_modules/react-externs/externs.js

✗ import reactExterns from 'react-externs'; // Not a module

This package provides raw Closure Compiler externs files, not JavaScript modules. Include them via --externs CLI flag.

externs.js file

✓ // Pass to compiler: closure-compiler --externs node_modules/react-externs/externs.js ...

✗ require('react-externs') // Returns unexpected object

Do not require or import the package; it exports nothing.

React externs (global)

✓ // Once included, Closure Compiler knows React API

✗ /// <reference path="react-externs/externs.js" /> // Only works in IDEs, not compiler

Reference path is not recognized by Closure Compiler; use --externs.

Shows how to install react-externs and use it with Closure Compiler via --externs flag.

// Install: npm install react-externs # Compile with Closure Compiler (example using google-closure-compiler): # npx google-closure-compiler \ # --js input.js \ # --externs node_modules/react-externs/externs.js \ # --compilation_level ADVANCED

Known issues

deprecatedThis package targets React 0.13 and is not updated for newer React versions.

fix

Use official React externs from Closure Compiler repository or upgrade to modern alternatives.

affects: >=0.12

gotchaDo not import or require the package; it only provides externs files for the compiler.

fix

Pass file path directly to Closure Compiler via --externs flag.

affects: >=0.12

gotchaExterns may be incomplete or inaccurate for React features beyond basic components.

fix

Verify coverage or consider using TypeScript .d.ts files converted to externs.

affects: >=0.12

Errors

Common errors & fixes

ERROR - [JSC_TYPE_MISMATCH] actual parameter 1 of React.createElement does not match formal parameter

Outdated externs not covering new React APIs like createElement signatures.

fix

Use a newer set of externs (e.g., from Closure Compiler contrib) or suppress warnings.

require('react-externs') returns {}

Package has no main export; it only provides externs files.

fix
