@neatfreak/eslint-plugin

This plugin provides opinionated, sensible rules that...

1. Help simplify ESLint setup.
2. Help you adhere to best practices.
3. Identify probable issue vectors in your code (pitfalls and code smells).
4. Maximize readability and understanding of your code.
5. Maximize ease of maintaining and refactoring your code.
6. Maximize consistency of style and practices.
7. Are designed to augment and/or compliment as opposed to override or conflict when using Prettier.

Rules that might cause excessive errors and are not auto-fixable are set to "warn".

For these reasons, many rules are enabled and, of those, most are using the recommended configuration except where it makes sense for achieving said goals. When used with Prettier, conflicting rules are disabled.

If there is a rule you just can't stomach, simply override it. This way you have a solid starting point. Publish your version publicly or privately and share it within your organization to maintain consistency between all your projects!

If you feel like any rule is just too cumbersome or restrictive, in general, please consider contributing to this project and let's make it better together!

5. Profit

"Hard mode" example

DIY file globs. Allows for more control over how configs are applied.

1{
2  "plugins": ["@neatfreak"],
3  "extends": [
4    "some-unrelated-config",
5    // apply @neatfreak configs after unrelated configs
6    "plugin:@neatfreak/base"
7  ],
8  "overrides": [
9    // if you need other unrelated overrides, add them first
10    {
11      "files": ["*.js"],
12      "rules": {
13        "semi": ["error", "always"]
14      }
15    },
16    {
17      "files": ["*.ts"],
18      "extends": [
19        "some-unrelated-config",
20        // apply @neatfreak configs after unrelated configs
21        "plugin:@neatfreak/typescript"
22      ],
23      "rules": {
24        "@typescript-eslint/semi": ["error", "always"],
25        "@typescript-eslint/init-declarations": "off"
26      }
27    },
28    {
29      "files": ["**/__tests__/**"],
30      // base config will get applied by above overrides
31      "extends": ["plugin:@neatfreak/jest"],
32      "rules": {
33        "jest/no-if": "warn"
34      }
35    },
36    // Apply last when using Prettier config
37    {
38      "files": ["*.?(ts,js)"],
39      "extends": ["plugin:@neatfreak/prettier"]
40    }
41  ]
42}

"Easy mode" example

Applies configs automatically wrapped in an override with a default files glob.

1{
2  "plugins": ["@neatfreak"],
3  "extends": [
4    "some-unrelated-config",
5    // apply @neatfreak configs after unrelated configs
6    "plugin:@neatfreak/base",
7    // applied using pattern matching
8    "plugin:@neatfreak/jest auto",
9    "plugin:@neatfreak/typescript auto",
10    // applied globally
11    "plugin:@neatfreak/prettier"
12  ],
13  // example rules overrides
14  "rules": {
15    "semi": ["error", "always"],
16    "@typescript-eslint/semi": ["error", "always"],
17    "@typescript-eslint/init-declarations": "off",
18    "jest/no-if": "warn"
19  }
20}

Note: the prettier, node, and cli configs do not have an "auto" config, as these don't typically require an override.

"Lazy mode" example

Automatically applies everything.

Note: requires installing all optional peer dependencies (see Usage)

1{
2  "plugins": ["@neatfreak"],
3  "extends": ["plugin:@neatfreak/lazy"],
4  // example rules overrides
5  "rules": {
6    "semi": ["error", "always"],
7    "@typescript-eslint/semi": ["error", "always"],
8    "@typescript-eslint/init-declarations": "off",
9    "jest/no-if": "warn"
10  }
11}
