Typescript eslint tsconfig resolution error in monorepo

Question

I have the following project structure:

/root
  /serviceA 
  /serviceB
  /serviceC 
  /serviceD 

Not all of the services are typescript / node based, so I want to avoid adding tsconfig into the root. Each service is setup as a complete unit with its own installation of eslint, ts, and own configuration.

Any ts service I open VScode shows the following error:

Parsing error: Cannot read file '/users/{me}/dev/{root}/tsconfig.json'.

This is correct, as there is no such file, so how do I force vscode & eslint to use the individual services configuration files?

Answer 1

Edit your .eslintrc file with:

module.exports = {
  parserOptions: {
    project: './tsconfig.json',
    tsconfigRootDir: __dirname,
  },
};

Answer 2

In .eslintrc you can set the path to tsconfig.json.

parserOptions : {
  project: './tsconfig.json',
},

Here’s an example where it is just set for ts files
