Running multiple Typescript 'tsc' commands

I am trying to build an NPM command which will transpile two Typescript projects that are contained in sub directories in my application and the start my server.

I have a public folder called 'src' which contains two folders, Server and Client. There are tsconfig.json files in both as they use different module systems.

I am trying to write a command in npm which will transpile both of these Typescript roots before starting the server ut can't figure out how to so it. I wuold have thought it was something similar to this if it was possible?

tsc /src/Server/*.ts && tsc /src/Client/*.ts && node /src/Server/server

Here are my two tsconfig.json files:

in /src/Server

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es5",
    "sourceMap": true
  },
  "exclude": [
    "node_modules"
  ]
}

and in /src/Client

{
  "compilerOptions": {
    "target": "ES5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  }
}

Is what I am trying to achieve possible here?

Thanks!
