@akio/eslint-plugin v2.0.0

@akio/eslint-plugin

Personal ESLint plugin for JavaScript, TypeScript and Angular with mainly configuration and some self-written rules. Feel free to suggest changes but I'll be keeping my tabs :)

Installation

Install via npm:

npm i --save-dev @akio/eslint-plugin

Setup

Create your eslint.config.mjs (Or eslint.config.js if "type": "module" is set in your package.json) file and configure it according to the steps in the Configuration section.

Updating

To update this package, follow all the steps of the installation guide again, except configuring the eslint.config.mjs file.

Configuration

Put the eslint.config.mjs file into the root folder of your project. Some default globals may be given, but they should be configured according to https://eslint.org/docs/latest/use/configure/language-options#predefined-global-variables

For JavaScript linting

eslint.config.mjs:

import globals from 'globals';
import akiolint from '@akio/eslint-plugin';

export default [
    ...akiolint.configs.javascript,
    {
        languageOptions: {
            ecmaVersion: 'latest',
            globals: {
                ...globals.browser,
            },
        },
    },
];

For TypeScript linting

eslint.config.mjs:

import globals from 'globals';
import akiolint from '@akio/eslint-plugin';

export default [
    ...akiolint.configs.typescript,
    {
        languageOptions: {
            ecmaVersion: 'latest',
            globals: {
                ...globals.browser,
            },
        },
    },
];

For Angular linting

eslint.config.mjs:

import globals from 'globals';
import akiolint from '@akio/eslint-plugin';

export default [
    ...akiolint.configs.typescript,
    ...akiolint.configs.angularTypescript,
    ...akiolint.configs.angularTemplate,
    {
        languageOptions: {
            ecmaVersion: 'latest',
            globals: {
                ...globals.browser,
            },
        },
    },
    {
        files: [
            '**/*.ts',
        ],
        rules: {
            '@angular-eslint/component-selector': [
                'error',
                {
                    type: 'element',
                    prefix: /* Replace with prefix for components */,
                    style: 'kebab-case',
                },
            ],
            '@angular-eslint/directive-selector': [
                'error',
                {
                    type: 'attribute',
                    prefix: /* Replace with prefix for components */,
                    style: 'camelCase',
                },
            ],
        },
    },
];

Migrate from V1

ESLint 9 threw everything ESLint 8 did out of the window and basically created a completely different linting infrastructure. All used plugins basically did the same, and so Akiolint was kind of forced to do the same. The easiest way to migrate from V1 is probably to just setup Akiolint again.

To remove Akiolint V1, remove the following things from your package.json:

• The update-akiolint script
• The @akio/eslint-plugin dependency
• All other dependencies with eslint in their name (@angular-eslint/..., @typescript-eslint/..., etc.)

Also remove all ESLint configuration files (like .eslintrc.json or .eslintrc.js) from your project.

Finally remove your package-lock.json and node_modules and then run npm i.

Now you can start with the Installation section above.
