35+
36+
Snippet from `src/elasticache-redis-cmd-stack.ts`
37+
38+
```typescript
39+
const elastiCacheRedisCMD = new ElastiCache.CfnReplicationGroup(
40+
this,
41+
elastiCacheRedisCMDName.toLowerCase(),
42+
{
43+
replicationGroupDescription: "ElastiCache for Redis Cluster Mode Enabled CDK",
44+
numCacheClusters: 2,
45+
automaticFailoverEnabled: true,
46+
engine: "redis",
47+
cacheNodeType: "cache.t4g.micro",
48+
cacheSubnetGroupName: elastiCacheSubnetGroup.ref,
49+
securityGroupIds: [elastiCacheSecurityGroup.securityGroupId]
50+
}
51+
);
52+
```
53+
54+
## Useful commands
55+
56+
* `npm run build` compile typescript to js
57+
* `npm run watch` watch for changes and compile
58+
* `npm run test` perform the jest unit tests
59+
* `npx cdk deploy` deploy this stack to your default AWS account/region
60+
* `npx cdk diff` compare deployed stack with current state
61+
* `npx cdk synth` emits the synthesized CloudFormation template
