Package Exports

eslint-plugin-typescript-heck
eslint-plugin-typescript-heck/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (eslint-plugin-typescript-heck) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

eslint-plugin-typescript-heck

This package includes extended eslint rules for usage with Typescript.

Rules

Name	Description
array-type-spacing	Enforces correct spacing between type name and square brackets of array types.
type-parameter-spacing	Enforces correct spacing between an identifier and type parameters.

array-type-spacing

This rule enforces correct spacing between type name and square brackets of array types. It also enforces no spaces between the square brackets.

🔧 The --fix option on the command line can automatically fix the problems reported by this rule.

Options

This rule takes one option:

"never" (default) enforces no space between type name and square brackets.
"always" enforces exactly one space between type name and square brackets.

"array-type-spacing": ["warn", "never"]

never:

👎 Examples of incorrect code for this rule:

const myVar: string [] = [];
function myFunc (parameter: number []) {
    // ...
}

👍 Examples of correct code for this rule:

const myVar: string[] = [];
function myFunc (parameter: number[]) {
    // ...
}

always:

👍 Examples of correct code for this rule:

const myVar: string [] = [];
function myFunc (parameter: number []) {
    // ...

There is an optional configuration object:

betweenDimensions:

"never" (default) enforces no space between consecutive square brackets.
"always" enforces exactly one space between consecutive square brackets.

    "betweenDimensions": "never"
}
