Overview

Configure Linear integrations across development, staging, and production environments with proper secret management and environment guards.

Prerequisites

• Separate Linear workspaces or API keys per environment
• Secret management solution (Vault, AWS Secrets Manager, GCP Secret Manager)
• CI/CD pipeline with environment variables
• Environment detection in application

Instructions

Step 1: Define Environment Config Structure

Create typed config with per-environment API keys, webhook secrets, team keys, and feature flags (e.g., disable webhooks in dev, enable debug in staging).

Step 2: Integrate Secret Management

Use Vault, AWS Secrets Manager, or GCP Secret Manager to store API keys securely. Fetch secrets at runtime in production.

Step 3: Build Environment-Aware Client Factory

Singleton client that auto-configures based on NODE_ENV with test injection support.

Step 4: Add Environment Guards

• requireProduction() for prod-only operations
• preventProduction() for dangerous dev operations
• safeDeleteIssue() that archives in prod, deletes in dev

Step 5: Configure Per-Environment Webhooks

Dev uses polling (localhost), staging uses full event set, production adds Label events.

Step 6: Set Up CI/CD

GitHub Actions with environment-scoped secrets for staging (main branch) and production (release branches).

See detailed implementation for full code examples including secret manager integrations and CI/CD workflows.

Output

• Environment-specific configuration active
• Secrets managed securely per environment
• Environment guards preventing accidental cross-env operations
• CI/CD deploying to correct environments

Error Handling

Examples

Validate Environment

NODE_ENV=staging npx ts-node scripts/validate-environment.ts
# Output: API Key: Valid, Default Team: Found, Webhook Secret: Set

Resources

• Linear API Authentication
• 12-Factor App Config
