eslint-plugin-ferramentas

This package contains 3 ESLint rules. As all these rules need configuration by default, no plugin preset is exported. Install it by running npm install --save-dev eslint-plugin-ferramentas

Rules

import-spaces

Enforces consistency of spacing between relative imports according to the folder each imports reference. Imports are grouped as defined in the configuration, spaces are only allowed between the groups. Non relative imports, and relative imports without a specified group will be considered to be each in their own group, thus having spaces between them as well.

Configuration

To configure the rule on .eslintrc.js, simply add:

/** @type {import('eslint-plugin-ferramentas').Options['import-spaces']} */
const options = {
    groups: ['^foo.*$', '^bar.*$'],
};

module.exports = { rules: { 'ferramentas/import-spaces': ['error', options] } };

Possible errors examples

🔧 Automatic fixes available

There should be no empty lines in a import group

There should be one empty line between import groups

Fixes

When configured with:

{
    "groups": ["^foo.*$", "^bar.*$"]
}

Will change:

import { DomainType } from 'static';

import { FooA } from './foo/a';

import { FooB } from './foo/b';
import { Bar } from './bar';

import { Other } from './other';

To:

import { DomainType } from 'static';

import { FooA } from './foo/a';
import { FooB } from './foo/b';

import { Bar } from './bar';

import { Other } from './other';

relative-import-order

Ensure relative imports appear in a specific order as set on the configuration. The paths must be set with root paths and not from the perspective of the files where the import actually happens.

Configuration

To configure the rule on .eslintrc.js, simply add:

/** @type {import('eslint-plugin-ferramentas').Options['relative-import-order']} */
const options = {
    sort: [
        {
            type: 'group',
            groups: ['src/utils', 'src/domain', 'src/react'],
        },
        {
            type: 'depth',
        },
        {
            type: 'name',
        },
    ],
};

module.exports = { rules: { 'ferramentas/relative-import-order': ['error', options] } };

Possible errors examples

🔧 Automatic fixes available

The path './foo/bar' is not listed. All imported paths need to be included, either in the groups (so they are sorted) or ignored

Imports from './foo' should be above the import from './bar'

Fixes

When configured with:

{
    "sort": [
        {
            "type": "group",
            "groups": ["top-library", "bottom-library"]
        },
        {
            "type": "depth"
        },
        {
            "type": "name"
        }
    ]
}

Will change (while on the file ./bottom-library/ExampleImporter.tsx):

import { Label } from '../bottom-library';
import { isBufferValid } from '../top-library';
import { SpanishInquisition } from '../non-listed/import-path';

To:

import { isBufferValid } from '../top-library';
import { Label } from '../bottom-library';
import { SpanishInquisition } from '../non-listed/import-path';

siloed-relative-import

Prevents importing of files in specific folders from other specified locations of the codebase through regex.

Configuration

To configure the rule on .eslintrc.js, simply add:

/** @type {import('eslint-plugin-ferramentas').Options['siloed-relative-import']} */
const options = {
    directories: [
        {
            filter: '^src/react',
            forbid: ['^src/http'],
        },
    ],
};

module.exports = { rules: { 'ferramentas/siloed-relative-import': ['error', options] } };

Possible errors examples

Importing of './foo' is forbidden on './moo'
