jscs-config-seegno

Seegno-flavored JSCS config.

Installation

$ npm install jscs jscs-config-seegno should --save-dev

Usage

Create an .jscsrc file with the following:

preset: seegno

Add the following script to your package.json:

{
  "scripts": {
    "lint": "jscs ."
  }
}

and run the linter with:

$ npm run lint

Custom rules

The preset includes the following list of custom rules.

disallowGeneratorsInDescribeFunctions

Disallows the usage of generators for the describe grouping primitive that features in testing frameworks such as mocha.

This rule helps to avoid incorrectly replacing the function signature with a generator declaration, which results in some cryptic errors when running the tests, since describe is not meant to be asynchronous.

Requires: mocha

Type: Boolean

Value: true

Example

disallowGeneratorsInDescribeFunctions: true

Valid

describe('foobar', function () {
  it('should work');
});

Invalid

describe('foobar', function *() {
  it('should work');
});

disallowOnlyFilterInTestFunctions

Disallows the usage of only for grouping primitives or test cases in mocha.

Although it might help to run individual tests locally, this rule helps to ensure the entire test suite runs, for instance, using build or pre-commit scripts.

Requires: mocha

Type: Boolean

Value: true

Example

disallowOnlyFilterInTestFunctions: true

Valid

describe('foobar', function () {
  it('should work');
});

Invalid

describe.only('foobar', function *() {
  it('should work');
});
 
describe('foobar', function *() {
  it.only('should work');
});

requireShouldAssertionExecution

Disallows the usage of test expectation properties in favor of methods with libraries such as should.

Due to the nature of some expectation libraries, it's easy to forget a method () which might result in an assertion that never gets executed. This rule is meant to avoid that issue.

Requires: should

Type: Boolean

Value: true

Example

requireShouldAssertionExecution: true

Valid

true.should.be.true();

Invalid

true.should.be.true;

requireSqlTemplate

Disallows the usage of raw SQL templates with interpolation.

This rule enforces the usage of a library such as sql-tag, which escapes data provided to an SQL query statement via interpolation, helping to avoid, for instance, potential injection attacks.

Requires: sql-tag

Type: Boolean

Value: true

Example

requireSqlTemplate: true

Valid

const column = '*';
const query = sql`SELECT ${column} FROM foobar`;
 
fn(sql`SELECT ${column} FROM foobar`)

Invalid

const column = '*';
const query = `SELECT ${column} FROM foobar`;
 
fn(`SELECT ${column} FROM foobar`)
