Overview

Safely upgrade Linear SDK versions and handle breaking changes with compatibility layers and gradual rollout.

Prerequisites

• Existing Linear integration
• Version control (Git) configured
• Test suite for Linear operations

Instructions

Step 1: Check Current and Latest Versions

set -euo pipefail
npm list @linear/sdk          # Current version
npm view @linear/sdk version  # Latest available

Step 2: Review Breaking Changes

Check GitHub releases and changelog for migration guides between your current and target versions.

Step 3: Create Upgrade Branch

set -euo pipefail
git checkout -b upgrade/linear-sdk-vX.Y.Z
npm install @linear/sdk@latest
npx tsc --noEmit  # Check for type errors

Step 4: Apply Migration Patterns

Common changes between versions: renamed fields, changed return types (direct to paginated), new required parameters, and removed methods.

Step 5: Create Compatibility Layer

Wrap breaking changes in a compat client to normalize behavior across versions.

Step 6: Test and Deploy

set -euo pipefail
npm test && npx tsc --noEmit && npm run lint
npm run deploy:staging && npm run test:integration

Step 7: Gradual Rollout

Use feature flags to toggle between old and new SDK behavior in production.

See detailed implementation for all migration patterns, compatibility layer code, and version-specific changes.

Version Compatibility Matrix

SDK Version	Node.js	TypeScript	Key Changes
1.x	14+	4.5+	Initial release
2.x	16+	4.7+	ESM support
3.x	18+	5.0+	Strict types

Output

• SDK upgraded to target version
• Breaking changes resolved
• Compatibility layer in place
• Tests passing on new version

Error Handling

Error	Cause	Solution
Property does not exist	Renamed field	Check migration guide for new name
Type not assignable	Changed type	Update type annotations
Module not found	ESM/CJS mismatch	Update import syntax
Runtime method missing	Version mismatch	Verify installed SDK version

Examples

Basic usage: Apply linear upgrade migration to a standard project setup with default configuration options.

Advanced scenario: Customize linear upgrade migration for production environments with multiple constraints and team-specific requirements.
