I want to update Property Bag items with pnp-core js. I can get the property bag items by the following code -
pnp.sp.web.select('AllProperties').expand('AllProperties').get()
But what is the code to update Property Bag items?
Theoretically, you should be able to leverage the processQuery rest endpoint, and perform a query like the one below, in order to update a site custom property bag:
import { SPHttpClient, SPHttpClientResponse, ISPHttpClientOptions } from '@microsoft/sp-http';
[...]
let myPropertyBag ="customPropbag1"
let myNewPropBagValue ="new value"
let clientServiceUrl = `${this.siteAbsoluteUrl}/_vti_bin/client.svc/ProcessQuery`;
let data = `<Request xmlns="http://schemas.microsoft.com/sharepoint/clientquery/2009" SchemaVersion="15.0.0.0" LibraryVersion="16.0.0.0" ApplicationName="Javascript Library"><Actions><ObjectPath Id="1" ObjectPathId="0" /><ObjectPath Id="3" ObjectPathId="2" /><ObjectPath Id="5" ObjectPathId="4" /><Method Name="SetFieldValue" Id="6" ObjectPathId="4"><Parameters><Parameter Type="String">${myPropertyBag}</Parameter><Parameter Type="Number">${myNewPropBagValue}</Parameter></Parameters></Method><Method Name="Update" Id="7" ObjectPathId="2" /><Query Id="8" ObjectPathId="2"><Query SelectAllProperties="true"><Properties /></Query></Query><Query Id="9" ObjectPathId="4"><Query SelectAllProperties="true"><Properties><Property Name="edrms_eFolderId" ScalarProperty="true" /></Properties></Query></Query></Actions><ObjectPaths><StaticProperty Id="0" TypeId="{3747adcd-a3c3-41b9-bfab-4a64dd2f1e0a}" Name="Current" /><Property Id="2" ParentId="0" Name="Web" /><Property Id="4" ParentId="2" Name="AllProperties" /></ObjectPaths></Request>`;
let httpPostOptions = {
headers: {
'accept': 'application/json',
'content-type': 'application/json',
'X-RequestDigest': this.formDigest
},
body: data
};
let serviceResponse: SPHttpClientResponse = await this.spHttpClient.post(clientServiceUrl, SPHttpClient.configurations.v1, httpPostOptions);
[...]
and then
let serviceJSONResponse: Array<any> = await serviceResponse.json();
Unfortunately, property bags are read-only in RESP API, so it's not possible right now, as the ideology of PnP JS Core is to be a wrapper around REST API only. JSOM API should be used instead now for writing to property bags.
