Thank you for working on this. We are also running into this issue.

cc @r0qs for code review if you don't mind.

Thanks @roninjin10, and sorry for the very late reply, let's do this. Could you please just add the following:

--- i/package.json
+++ w/package.json
@@ -3,6 +3,7 @@
   "version": "0.8.28",
   "description": "Solidity compiler",
   "main": "index.js",
+  "types": "index.d.ts",
   "bin": {
     "solcjs": "solc.js"
   },

However, please note that this will not fully expose all types, as there is still some missing support that needs to be implemented: #615. Nevertheless, it is a step in the right direction, and I believe there is no harm in taking this as a first step.

I got some types here that I have been using past couple years for Tevm. Anyone is free to copy
