# Lokalise SDK Patterns ## Overview Production-grade patterns for `@lokalise/node-api`: client singleton, cursor pagination, typed error handling, batch operations, upload monitoring, and retry with rate limiting. ## Prerequisites - `@lokalise/node-api` v12+ installed - TypeScript 5+ with `strict` mode ## Instructions 1. Create a client singleton to centralize configuration and support branch-based project IDs. ```typescript // src/lib/lokalise-client.ts import { LokaliseApi } from "@lokalise/node-api"; let instance: LokaliseApi | null = null; export function getClient(apiKey?: string): LokaliseApi { if (instance) return instance; const key = apiKey ?? process.env.LOKALISE_API_TOKEN; if (!key) throw new Error("Set LOKALISE_API_TOKEN or pass apiKey"); instance = new LokaliseApi({ apiKey: key, enableCompression: true }); return instance; } export function resetClient(): void { instance = null; } /** Lokalise branch syntax: "projectId:branchName" */ export function projectId(id: string, branch?: string): string { return branch ? `${id}:${branch}` : id; } ``` 2. Build a cursor-based pagination helper that works with any paginated endpoint. ```typescript // src/lib/paginate.ts interface PaginatedResult<T> { items: T[]; hasNextCursor(): boolean; nextCursor(): string; } type Fetcher<T> = (params: Record<string, unknown>) => Promise<PaginatedResult<T>>; /** Async generator yielding all items across pages with rate-limit spacing. */ export async functi...
