Firebase database.ServerValue.TIMESTAMP get current time

By -
Firebase Server Time STAMP can only retive the value when it comminted to firebase database

var currentTimeStamp=firebase.database.ServerValue.TIMESTAMP;

value for this will be set when datbase operation like set ,push or update occures .

In order to get the value you need to write code like below.


  ref.child(test).child(time-stamp').set(firebaseAdmin.database.ServerValue.TIMESTAMP).then(function() {

                          ref.child(test).once('value').then(function(Snapshot) {
                         
                               var currentTimeStamp= Snapshot.val()['time-stamp'];

});
});

React-qill  is a great free package which can be used for design editors. However, if you are using the image upload feature, there is a problem of integrating resize package. This was discussed in may treads and I was able to find the best approach integrate it with react-starter-app. https://www.npmjs.com/package/quill-image-resize-module If you use the following code, import Quill from ' quill ' ; import { ImageResize } from ' quill-image-resize-module ' ; Quill . register ( ' modules/imageResize ' , ImageResize); const quill = new Quill (editor, { // ... modules : { // ... imageResize : { // See optional "config" below } } }); The following error is common.
