utility-pickle bundles several small TypeScript helpers under a single static Pickle class. The utilities focus on common runtime checks, functional piping, value transformations and handy regular expressions.
npm install utility-pickle
import { Pickle } from 'utility-pickle';
// Runtime guard
if (Pickle.guard.isString('hello')) {
// narrowed to string
}
// Function pipeline
const addDouble = Pickle.pipe
.then((n: number) => n + 1)
.then((n) => n * 2)
.build();
console.log(addDouble(3)); // 8
// String transformation
const kebab = Pickle.transformation.string.toKebabCase('Hello World'); // 'hello-world'
// Regex example
const tokens = 'foo-bar_baz'.split(Pickle.regex.separatorAndChar);
PickleCentral namespace that exposes all utilities.
export class Pickle {
public static readonly guard = Guard;
public static readonly pipe = Pipe;
public static readonly transformation = Transformation;
public static readonly regex = Regex;
}
Runtime type guards such as isString, isNumber, and tuple checks. See src/guard/guard.ts for the full set of helpers and GuardFactory for dynamic guard creation.
Fluent builder for composing functions. Begin with Pipe.then() and finalize with build() to obtain the composed function. Implemented in src/pipe/pipe.ts and src/pipe/pipeBuilder.ts.
String and number utilities along with a helper to start pipelines via Transformation.pipe().
Useful regular expression constants like whitespace or digit matches, located in src/regex/regex.ts.
