Building guide

When building the front-end you might run into issues with incompatable tsconfigs between the client and server(s).

It's normal for your back-end and front-end to have different configurations. Since TSDL never imports any runtime code from your server, the issue of the TypeScript compiler type checking server side code can be mitigated.

How to skip tsc checking server files

Client side

Make sure your client's tsconfig.json has "compilerOptions.skipLibCheck": true and add the path or package name (if you use a monorepo) to the types directive in your tsconfig.json.

client/tsconfig.json

{
  "compilerOptions": {
    /* ... */
    "skipLibCheck": true
    /* ... */
  },
  "types": ["backend"] // the path or module name to your backend package
}

Server side

Add the following to your back-end's package.json.

This will point the tsc compiler to the types location instead of the actual code thereby skipping type checking.

backend/package.json

{
  "name": "backend",
  ...
  "types": "dist",
  "scripts": {
    "build:types": "tsc --outDir dist --declaration --emitDeclarationOnly",
    ...
  }
  ...
}

You can build however you want, the important thing is that declaration files are built somewhere. Therefore, you don't necessarily need --emitDeclarationOnly if you want .js files in your output directory.

Building front-end

npm run build:types in your back-end
npm run build in your front-end

This should make the TypeScript compiler skip type checking your backend since skipLibCheck ignores .d.ts files.
