@linzjs/style

NPM configuration for base typescript projects

Includes:

• Prettier
• Eslint
• Typescript

And configuration for saneish defaults, which can be extended

Most of these are the raw defaults/recommended settings from typescript, eslint and prettier.

export class FooBar {
  get foo(): number {
    return 1;
  }

  async bar(): Promise {
    return 'bar';
  }

  /**
   * @param foo foo to bar
   */
  fooBar(foo = 'foo'): string {
    return `${foo}bar`;
  }
}

IDE Usage

Usage VS Code

1. Install eslint using the extensions menu
2. Add the following to your settings.json

"editor.codeActionsOnSave": {
    "source.fixAll.eslint": true
},
"eslint.validate": ["javascript"],

Usage with IntelliJ

IntelliJ has ESLint support by default,

1. Open the settings in Languages & Frameworks > JavaScript > Code Quality Tools > ESLint
2. Check Automatic ESLint Configuration

Project Usage

1. Install LINZ Style

npm install @linzjs/style

2. Applying eslint config There are two ways to apply the config

Either create the base configuration files

# If on windows run `node ./node_modules/@linzjs/style/build/src/install.js`
# - tsconfig.json
# - .eslintrc.cjs
# - .prettierrc.cjs
npx linz-style-install

Or extend your existing eslintrc.js config

Example extending the .eslintrc.js file in your project

module.exports = {
  extends: ["./node_modules/@linzjs/style/.eslintrc.cjs"],

  overrides: [
    {
      /** Overrides for typescript */
      files: ["**/*.ts", "**/*.tsx"],      
      rules: {
        "@typescript-eslint/super-crazy-hook-rule": "error",
      },
    },
  ]
}

3. Apply the formatting/linting to all source code

npx eslint .
