Should you need to create a custom datasource, it is a straightforward task involving javascript development. The high level steps involved are as follows:

1. Create a javascript file (ex. my_datasource.js)
2. Implement the datasource schema
3. Specify datasource settings
4. Implement the datasource model
5. Host the javascript file on a file server or upload it to github
6. Link the custom datasource to the portal within the ClearBlade developers console
