[shekhar-shubhendu]

@shrey0921 Somehow the application is not able to resolve truffle contract build directory. Have you run truffle migrate before running npm start? if yes, then can you provide a screenshot of your directory structure and output of truffle compile

[shrey0921]

i was able to run the command truffle compile and above errors are resolved... now compiler is showing webpack compiled successfully...after going to localhost:4200/ the applicatoin shows loading and blank page.

[shekhar-shubhendu]

Great. Please check for errors in the browser console and if any please paste them here.

[shrey0921]

browser is not giving any errors just some warnings. browser keeps on loading...

[shekhar-shubhendu]

Please check if you have followed all the instructions. Without an error log it will be difficult to debug.
