You can call ObsClient.getBucketLifecycle to view lifecycle rules of a bucket. Sample code is as follows:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret Key ***',       
    server : 'https://your-endpoint'
});

obsClient.getBucketLifecycle({
       Bucket: 'bucketname'
}, function (err, result) {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                     for(var i=0;i<result.InterfaceResult.Rules.length;i++){
                           console.log('Rule[' + i + ']:');
                           console.log('ID-->' + result.InterfaceResult.Rules[i]['ID']);
                           console.log('Prefix-->' + result.InterfaceResult.Rules[i]['Prefix']);
                           console.log('Status-->' + result.InterfaceResult.Rules[i]['Status']);
                           for(var j=0;j<result.InterfaceResult.Rules[i]['Transitions'].length;j++){
                                  console.log('Transition[' + j + ']:');
                                  console.log('Transition[StorageClass]-->' + result.InterfaceResult.Rules[i]['Transitions'][j]['StorageClass']);
                                  console.log('Transition[Date]-->' + result.InterfaceResult.Rules[i]['Transitions'][j]['Date']);
                                  console.log('Transition[Days]-->' + result.InterfaceResult.Rules[i]['Transitions'][j]['Days']);
                           }
                           console.log('Expiration[Date]-->' + result.InterfaceResult.Rules[i]['Expiration']['Date']);
                           console.log('Expiration[Days]-->' + result.InterfaceResult.Rules[i]['Expiration']['Days']);
                           for(var k=0;k<result.InterfaceResult.Rules[i]['NoncurrentVersionTransitions'].length;k++){
                                  console.log('NoncurrentVersionTransition[' + k + ']:');
                                  console.log('NoncurrentVersionTransition[StorageClass]-->' + result.InterfaceResult.Rules[i]['NoncurrentVersionTransitions'][k]['StorageClass']);
                                  console.log('NoncurrentVersionTransition[NoncurrentDays]-->' + result.InterfaceResult.Rules[i]['NoncurrentVersionTransitions'][k]['NoncurrentDays']);
                           }
                           console.log('NoncurrentVersionExpiration[NoncurrentDays]-->' + result.InterfaceResult.Rules[i]['NoncurrentVersionExpiration']['NoncurrentDays']);
                     }
              }
       }
});
