my env:

Angular CLI: 9.1.6
Node: 14.15.3
OS: darwin x64

Managed to build the UI and include it with the JAR file. UI works fine on ThingsBoard CE 3.3.3 but doesn't seem to work with 3.2.2.

I used the steps introduced in the Readme to build, but there were too many errors. Is this project still under maintenance?

Ran into the same issue as #26, and I do not think the solution proposed should be considered enough to close the issue.

If you want to keep your own set of custom rule nodes with custom ui components and templates, it does not make sense to keep around the entire rule-config-ui-ngx repo.

Hello, Sir!
I follow Create a custom rule node,

I used two projects: https://github.com/thingsboard/rule-node-examples and https://github.com/blackstar-baba/rule-node-examples-ui-ngx

1. I followed: node examples UI-NGX step5: deploy rule nodes UI JavaScript code to rule node examples
   Resulting custom-nodes-config. js should be copied to rule-node-examples/src/main/resources/public/static/rulenode/ directory of rule-node-examples repository.

2. In rule node examples: MVN clean install

3 sudo cp rule-engine-1.0. 0-custom-nodes. jar /usr/share/thingsboard/extensions/

4 sudo service thingsboard restart

5 when I add the newly created rule node, it prompts: failed to load configuration UI resources

Can you remind me of any mistakes? Thanks
