Handle Errors Gracefully + +```typescript +try { + const result = await neurolink.generate({ + input: { + text: "Analyze this PDF", + pdfFiles: ["document.pdf"], + }, + provider: "vertex", + }); +} catch (error) { + if (error.message.includes("not currently supported")) { + console.error("PDF not supported by this provider.

Try: --provider google-ai-studio"); + } else if (error.message.includes("Invalid PDF")) { + console.error("File is not a valid PDF format"); + } else { + console.error("Error:", error.message); + } +} +``` + +### 4. Use Streaming for Large Documents + +```typescript +// For long documents, use streaming to get results faster +const stream = await neurolink.stream({ + input: { + text: "Provide a detailed analysis of this 50-page report", + pdfFiles: ["long-report.pdf"], + }, + provider: "vertex", + maxTokens: 8000, +}); + +for await (const chunk of stream) { + process.stdout.write(chunk.content); +} +``` + +### 5.
