File paths in node.js site

First time building a big project using node.js.

I want to use echarts.js since Wappler charts does not suite my needs with the project.

I created a js folder in the public folder and added the echarts.js file there like this:

On my content page I added the script link and the test graph displays in Wappler but does not when opening the web page in the browser. Please help me fix this so graph will display on live page. Thanks
