Licensing Overview

Syncfusion license key validation was introduced in the 2022 Volume 1 release (v20.1.0.47) for Essential JS2 platforms. All Angular applications referencing Syncfusion packages from npm, CDN, or build must register a valid license key to avoid validation warnings.

Key Licensing Details

License Key vs Unlock Key:

• License Key: String registered in application code to validate Syncfusion package usage
• Unlock Key: Used only during Syncfusion installer process
• ⚠️ Important: License key is NOT the same as installer unlock key

Core Requirements:

• License key validation introduced in v20.1.0.47+ (2022 Volume 1)
• License keys are version and platform/edition specific
• Validation occurs offline (no internet required during runtime)
• Required when using npm packages or trial installers
• Not required when using licensed installers

License Types:

• Trial license: 30-day evaluation period, full functionality, generates trial key, displays warning after expiration
• Community license: Free for qualifying individuals/organizations (<$1M USD revenue), same functionality as paid license, annual renewal required
• Paid license: Commercial license for enterprise use, perpetual or subscription-based, technical support included

Edition-Based vs Platform-Based:

• v31.1.17+ (Edition-based): UI Edition, Document SDK, PDF Viewer SDK, DOCX Editor SDK, Spreadsheet Editor SDK, Enterprise Edition (all editions combined)
• v30.x.x and earlier (Platform-based): Angular, React, Vue, JavaScript, Blazor, etc.

Build Server Scenarios:

• Using npm packages: License key required - register using NPX command
• Using trial installer: License key required - trial warnings appear after 30 days
• Using licensed installer: License key NOT required - embedded license validation included

Offline Validation:

• No internet connection required during application runtime
• License validated locally against package metadata at startup
• Works in air-gapped environments and offline development
• No external API calls or performance impact

License Key Registration

Table of Contents

• Overview
• Register License with Environment Variables
• CI/CD Integration

Overview

The generated Syncfusion license key must be registered in your Angular application. The recommended approach is to use environment variables to avoid accidentally committing license keys to source control.

Important Notes:

• License validation is performed offline during application execution
• No internet connection required after registration
• Apps can be deployed on any system without internet access
• License key registration required from v20.1.0.47+ (2022 Volume 1) onwards

Register License with Environment Variables

The recommended way to register your Syncfusion license key is using environment variables. This approach keeps your license key secure and prevents accidental commits to source control.

Step 1: Set Environment Variable

Set the SYNCFUSION_LICENSE environment variable on your system with your license key.

Windows

Open command prompt and use the setx command:

setx SYNCFUSION_LICENSE "Your_License_Key_Here"

Mac

Open terminal and add to your bash profile:

echo 'export SYNCFUSION_LICENSE="Your_License_Key_Here"' >> ~/.bash_profile

To modify the environment variable:

nano ~/.bash_profile

Press Ctrl+X to exit, then Y and Enter to save changes.

Close and reopen terminal to see the changes using env command.

Linux

Open terminal and set the environment variable:

export SYNCFUSION_LICENSE='Your_License_Key_Here'

Step 2: Restart your IDE or terminal

After setting the environment variable, restart your IDE or application terminal.

Step 3: Activate the license

Open command prompt in the application root directory and run:

npx syncfusion-license activate

Success message:

(INFO) Syncfusion License imported successfully.

Step 4: Clear cache

Remove the .cache folder from node_modules:

# Windows PowerShell
Remove-Item -Recurse -Force node_modules\.cache

# macOS/Linux
rm -rf node_modules/.cache

Note: For alternative license registration methods, kindly refer to the Syncfusion license key registration documentation.

CI/CD Integration

Important: Always use secret management systems in CI/CD pipelines. Never hardcode license keys in workflow files or commit them to source control.

GitHub Actions

Use environment variables in GitHub Actions to register your license in CI pipelines.

Step 1: Create a Repository Secret

1. Go to your repository → Settings → Secrets and variables → Actions 2. Click "New repository secret" 3. Name: SYNCFUSION_LICENSE 4. Value: Your license key 5. Click "Add secret"

Or create an Organization Secret to share across repositories.

Step 2: Add activation step to your workflow

# WARNING: Always use secrets, never hardcode license keys in workflow files
steps:
  - name: Install node modules
    run: npm install

  - name: Activate Syncfusion License
    run: npx syncfusion-license activate
    env:
      SYNCFUSION_LICENSE: ${{ secrets.SYNCFUSION_LICENSE }}

Complete Example:

# WARNING: Always use secrets, never hardcode license keys in workflow files
name: Build Angular App

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  build:
    runs-on: ubuntu-latest
    
    steps:
      - name: Checkout code
        uses: actions/checkout@v4
      
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
      
      - name: Install dependencies
        run: npm install
      
      - name: Activate Syncfusion License
        run: npx syncfusion-license activate
        env:
          SYNCFUSION_LICENSE: ${{ secrets.SYNCFUSION_LICENSE }}
      
      - name: Build application
        run: npm run build

Azure Pipelines (YAML)

Use environment variables in Azure Pipelines to register your license.

Step 1: Create a User-defined Variable

1. Navigate to your pipeline → Edit → Variables 2. Click "New variable" 3. Name: SYNCFUSION_LICENSE 4. Value: Your license key 5. Check "Keep this value secret"

Step 2: Add activation step to your pipeline

For Windows build agents:

# WARNING: Always use secret variables, never hardcode license keys in pipeline files
pool:
  vmImage: 'windows-latest'

steps:
  - script: call npm install
    displayName: 'Install node modules'

  - script: call npx syncfusion-license activate
    displayName: 'Activate Syncfusion License'
    env:
      SYNCFUSION_LICENSE: $(SYNCFUSION_LICENSE)

For Linux build agents:

# WARNING: Always use secret variables, never hardcode license keys in pipeline files
pool:
  vmImage: 'ubuntu-latest'

steps:
  - script: npm install
    displayName: 'Install node modules'

  - script: npx syncfusion-license activate
    displayName: 'Activate Syncfusion License'
    env:
      SYNCFUSION_LICENSE: $(SYNCFUSION_LICENSE)

Azure Pipelines (Classic)

For Classic Editor users:

Step 1: Create a User-defined Variable named SYNCFUSION_LICENSE with your license key as the value. Make sure to mark it as secret.

Step 2: Add a Bash task after npm install with the following script:

# WARNING: Ensure SYNCFUSION_LICENSE is stored as a secret variable
# Never hardcode license keys in scripts
npx syncfusion-license activate

Configuration Mismatch Solutions

Explicit @syncfusion/ej2-base Dependency

Remove @syncfusion/ej2-base from package.json (auto-installed with other packages):

{
  "dependencies": {
    "@syncfusion/ej2-angular-grids": "25.1.35"
    // ✅ @syncfusion/ej2-base installed automatically
  }
}

Then: Delete node_modules, package-lock.json → npm install → Clear cache

Major Version Conflict with ^ Symbol

Use ~ (tilde) instead of ^ (caret) to prevent major version upgrades:

{
  "dependencies": {
    "@syncfusion/ej2-angular-grids": "~25.1.35",  // ✅ Only 25.1.x patches
    "@syncfusion/ej2-angular-buttons": "~25.1.35"
  }
}

Version symbols:

• ^25.1.35 - Allows 25.x.x ❌
• ~25.1.35 - Only 25.1.x ✅
• 25.1.35 - Exact version ✅

Platform Mismatch Error

Error Message

The included Syncfusion license key is not valid for this platform.

Cause (v30.x.x and Earlier)

License key generated for one platform but used in another (e.g., React key in Angular project).

cat package.json | grep "@syncfusion"
# Expected for Angular: "@syncfusion/ej2-angular-*"

Generate correct platform key: 1. Go to License Portal 2. Select version 30.x.x or earlier 3. Select platform: Angular 4. Generate key

Note: For v31.1.17+, platform mismatch errors don't occur - UI Edition/Enterprise Edition keys work across all platforms.

Version Mismatch Error

Error Message

The included Syncfusion license key is not valid for version {installed_version}.

Cause

License key version doesn't match installed package version.

Solution

Step 1: Check all Syncfusion package versions
