# Linear Multi-Environment Setup ## Overview Configure Linear integrations across dev, staging, and production with isolated API keys, secret management, environment guards, and per-environment webhook routing. Use separate Linear workspaces or at minimum separate API keys per environment. ## Prerequisites - Separate Linear API keys per environment (dev, staging, prod) - Secret management (Vault, AWS Secrets Manager, GCP Secret Manager) - CI/CD pipeline with environment support - Node.js 18+ ## Instructions ### Step 1: Environment Configuration ```typescript // src/config/linear.ts import { LinearClient } from "@linear/sdk"; interface LinearEnvConfig { apiKey: string; webhookSecret: string; defaultTeamKey: string; enableWebhooks: boolean; enableDebugLogging: boolean; cacheEnabled: boolean; } type Environment = "development" | "staging" | "production" | "test"; function getEnvironment(): Environment { const env = process.env.NODE_ENV ?? "development"; if (!["development", "staging", "production", "test"].includes(env)) { throw new Error(`Unknown NODE_ENV: ${env}`); } return env as Environment; } async function loadConfig(): Promise<LinearEnvConfig> { const env = getEnvironment(); // In production, use secret manager instead of env vars if (env === "production" || env === "staging") { return { apiKey: await getSecret(`linear-api-key-${env}`), webhookSecret: await getSecret(`linear-webhook-secret-${env}`), defaultTeamK...
