I think what you mean by running it without gulp would be to package and deploy the webpart to SharePoint.
For that, you can follow the below steps:
1) Once you are done with the your local development, we need to configure a CDN path where we can host our files.
Go to the
config > write-manifests.json file.
Here, enter your CDN path. It should be a path that can be accessible by the end users. It could be Azure or SharePoint or any thing else.
Modify it as below (sample code) and save the file:
2) Now, you need to generate the files to be deployed.
For that run the below command:
gulp bundle –ship
After this is done, you will find the a
temp > deploy folder inside your solution as below:
Once this is generated, upload all the files inside the deploy folder to your CDN or Site Assets (as in our case). This task can also automated using advanced gulp tasks.
3) Now, we will create
spapp file to be uploaded to app catalog.
For that, run the below command:
gulp package-solution –ship
This will generate an sppkg file inside
sharepoint folder as below:
Upload it to the app catalog. SharePoint will show you a popup and ask you to trust the client-side solution to deploy.
After that, you can add it like you add an App in a SharePoint site.
