/** * CRITICAL: This file is imported for its side effects to patch the environment * for Node.js compatibility before any other library code runs. * * It ensures that by the time Transformers.js/ONNX Runtime is imported by any other * module, the necessary compatibility fixes for the current Node.js * environment are already in place. * * This file MUST be imported as the first import in unified.ts to prevent * race conditions with library initialization. Failure to do so may * result in errors like "TextEncoder is not a constructor" when the package * is used in Node.js environments. * * The package.json file marks this file as having side effects to prevent * tree-shaking by bundlers, ensuring the patch is always applied. */ // Get the appropriate global object for the current environment const globalObj = (() => { if (typeof globalThis !== 'undefined') return globalThis if (typeof global !== 'undefined') return global if (typeof self !== 'undefined') return self return null // No global object available })() // Define TextEncoder and TextDecoder globally to make sure they're available // Now works across all environments: Node.js, serverless, and other server environments if (globalObj) { if (!globalObj.TextEncoder) { globalObj.TextEncoder = TextEncoder } if (!globalObj.TextDecoder) { globalObj.TextDecoder = TextDecoder } // Create special global constructors for library compatibility ;(globalObj as any).__TextEncoder__ = TextEncoder ;(globalObj as any).__TextDecoder__ = TextDecoder } // Also import normally for ES modules environments import { applyTensorFlowPatch } from './utils/textEncoding.js' // Apply the TextEncoder/TextDecoder compatibility patch applyTensorFlowPatch() console.log('Applied TextEncoder/TextDecoder patch via ES modules in setup.ts')
