ESLint rules for NativeScript projects.

1. Install

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

2. Add an .eslintrc.json config file with the following content.

.eslintrc.json

{
  "parser": "@typescript-eslint/parser",
  "parserOptions": {
    "sourceType": "module",
    "ecmaVersion": 2015
  },
  "plugins": ["@nativescript"],
  "extends": [
    "plugin:@nativescript/recommended"
  ]
}

3. Lint the project.

npx eslint --ext=ts src/

Notice that you need to provide the path to your source code. In the example above, we use src/. Change that to match your project setup.

4. Fix all auto-fixable problems.

npx eslint --ext=ts --fix src/

5. [Optional] Set up VSCode to use eslint.

• Install the dbaeumer.vscode-eslint extension.
• Add the following to your settings.json file:

"eslint.validate": [ "typescript", "javascript" ],
