npm i -D eslint-import-resolver-typescript @typescript-eslint/eslint-plugin @typescript-eslint/parser

TypeScript is already supported in following configurations:

• plugin:smile/js
• plugin:smile/react
• plugin:smile/angular
• plugin:smile/next
• plugin:smile/nuxt

For Vue use plugin:smile/vue-ts instead.

If you want to use additional rules that require type checking (see https://typescript-eslint.io/linting/typed-linting/) you can add install additional peerDependency:

npm i -D @typescript-eslint/eslint-plugin @typescript-eslint/parser

And add the following configuration plugin:smile/ts (in addition to your framework configuration) and add the parserOptions.project option (see https://typescript-eslint.io/packages/parser/#project).

Example:

{
  "extends": ["plugin:smile/next", "plugin:smile/ts"],
  "parserOptions": {
    "project": ["./tsconfig.json"]
  }
}

This package use eslint-plugin-prettier to format the code with prettier through eslint.

We recommend using a .prettierrc file a the root of your project and apply the following configuration:

{
  "singleQuote": true
}

Also create a .editorconfig file with:

[*]
charset = utf-8
insert_final_newline = true
end_of_line = lf
indent_style = space
indent_size = 2
max_line_length = 80
trim_trailing_whitespace = true

For angular add the following configuration into the .prettierrc file:

{
  "overrides": [
    {
      "files": "*.html",
      "options": {
        "parser": "angular"
      }
    }
  ]
}

You can override some rules in the rule section:

{
  "extends": ["plugin:smile/js"],
  "rules": {
    "no-underscore-dangle": ["error", { allow: ["__schema"] }],
    // ...
  }
}
