TSLint provides no means of controlling spaces before colon in object literals and destructuring assignments. whitespace.check-type checks only for space after colon, and typedef-whitespace works only for type definitions.
This rules determines if a space is required or not before the colon in object literals and destructuring assignments.
Related to palantir/tslint#991.
Install with NPM or Yarn to your dev dependencies:
npm install --save-dev tslint-whitespace-before-colon
and include it in your project's tslint.json file. You can do it either by adding the package name to extends field:
"extends": [
"tslint-whitespace-before-colon"
]or by adding the package location to rulesDirectory field:
"rulesDirectory": [
"node_modules/tslint-whitespace-before-colon"
]Both approaches are equivalent, use whichever suits your project the most.
Rule expects a single string option indicating the required number of spaces before colon:
"nospace"requires no space"onespace"requires exactly one space"space"requires one or more spaces
If none of the above is provided, the rule will have no effect.
Example configuration:
"rules": {
"whitespace-before-colon": [true, "nospace"]
}If a newline character ("\n") is present, the rule validates regardless of the configured option, just as typedef-whitespace rule does.
