Errors

ESLint couldn't find the plugin "eslint-plugin-jest"

Unfortunately eslint doesn't officially support plugins as dependencies in shareable configs (See eslint#3458). The result is, that eslint doesn't find these plugins. However, we want this package to be as convient to use as possible, so we don't plan to add these plugins as peerDependencies.

If you see a complain like "eslint-plugin-jest", simply install this dependency explicitly:

yarn add --dev --exact eslint-plugin-jest

With more recent package managers, dependencies are installed in a flat way. That means, that dependencies and secondary dependencies are installed directly in the top level node_modules directory (See how npm3 works).

Parsing error: Cannot read file [...]tsconfig

Reference directly to your .tsconfig.

//.eslintrc
{
  // ...
      "parserOptions": {
      "project": "./tsconfig.json"
    },
 // ...
}
