Lesson 13: front_end/src/deployments/map.json file

[toddabraham]

Hi there,

I may have missed something, but are we supposed to create the map.json file, or is it automatically created and populated after a deployment?

This is a tricky one, but let me try to solve the question.

When you compile a project on Brownie, Map.json gets generated automatically saving the recent deployments yo made, the info of the networks comes directly from brownie-config.yaml. As JavaScripts cannot understand things outside the src you send that information at deployment with the update_front_end function which sends a Json File.

Also you need the build folder so you send it using copy_folders_to_frontend function

As you can see, map.jsoncomes from brownie compilation.

Hope this might solve your question.

Thanks again @cromewar . I had done all you suggested, the issue was in my .env I hadn't included my ETHER_SCAN API token ID.

I'm glad you solved it, feel free to make any another question.
