我想用 javascript 语言构建 NestJS 应用程序，但它在 tsconfig.json 上给出了一些错误

Question

Can you help me how to build nestjs with language javascript? i was create the nestjs app with "nest new --language js new-app-name", and i want to deploy it into vercel. i was try to build with nest build but it show an error message like this: " Error Could not find TypeScript configuration file "tsconfig.json". Please, ensure that you are running this command in the appropriate directory (inside Nest workspace)". after read the message i check my files again and i found that i doesn't have tsconfig.json but i have an jsconfig.json.

so, is anybody have some soution with my problems? i'll be glad if someone know how to fix it. Thank you

i was try to change the command like: "nest build --project jsconfig.json" "nest build --jsonfig jsconfig.json" "npm run build"

but it doesn't work

I expect my nestjs can build properly

nest build only works with .ts files. For writing and running a Nest application in regular JavaScript you'll need to use babel with the run command being babel-node index.js . There's no "building" to be done, so nest build won't do anything.
