How to reload express.js server with esbuild

Hello!!
I'm trying to develop web server made of express.js. And I want to use esbuild as bundler, but esbuild don't have feature to realod server. So I tried to add the feature.

Finally, I used nodemon. Like below.

{ "watch": [ "src" ], "ignore": [ "dist", "node_modules" ], "ext": "ts,mjs,js,json,graphql", "exec": "yarn build && yarn start", "legacyWatch": true } 

But it isn't best way to reload because that code regenerate all code... ... If you have another solution, I want to know that!!
