This is a continuation post in the SharePoint Framework Development series, In a previous article, we saw how to set up the development environment for SharePoint Framework. We also saw the basic Hello World web part creation and how to provision SharePoint List with custom Site Columns and Content Type here. In this article, we will see how to upgrade the previous solution that was used to deploy a list so that we can deploy a second list along with the same solution.The main code files used for this demo is uploaded here.
Once we have deployed the solution if we must make some changes at a later point, upgrade actions are available. Deploying without an upgrade will install a fresh copy of the solution. To retain the existing data, we will go with the upgrade option. However, to do the upgrade, we should add a new element file say elementsV2.xml.
In our case, we are trying to add a new list along with the previously deployed solution(The previous solution had already deployed a list named Employee ). In the new elements file, we will specify the list instance declaration for the new list.
We will also add an upgrade action which will contain the information about the newly added elements.xml file. It contains the relative location of the new elements file with respect to the feature ID.
As the last step we have to update the package-solution.json file by adding elementsV2.xml to the elementsmanfiest tag and we will also add the upgrade actions file reference.Before updation the json file looks like the one below:
After adding the new elements file and upgrade action reference, we will also increment the version number to 22.214.171.124
Save the files and run gulp serve to package the solution file. Now let’s go ahead and upload the sppkg solution file to SharePoint App Catalog.
Upon clicking on OK it will give a warning whether to replace it with the new solution. Click on Replace It so that the new version is added.
We can see that the version has upgraded from 126.96.36.199 to 188.8.131.52
Heading over to the site contents we can see that the new list ‘ListAddedViaUpgrade’ has been provisioned in addition to the existing Employee list.
Once the solution has been uploaded to SharePoint, ensure that there are no errors mentioned in the below columns.
At times if we have some error in the package, it will be displayed as shown below. Ensure that we resolve any such errors by analyzing the error message. The below error was thrown because of a white space at the beginning of the Elements.XML file.
Thus, we saw how to upgrade the SharePoint Framework solution using upgrade actions. Stay tuned for more SharePoint Framework articles.
