@jdsalasc/solvejs

Zero-dependency JavaScript and TypeScript utility suite for real production pain points.

Includes date, string, list, regex, constants, numbers, validators, object, async, and schema utilities.

When to use this package

Use it when your project needs multiple utility domains and you prefer one import surface over many package-level imports.

Limitations and Constraints

• Utilities prioritize predictable defaults over framework-specific abstractions.
• Date and number helpers do not replace domain-specific finance/timezone libraries for regulated calculations.
• Import package-level modules directly when you need strict control over bundle boundaries.

Install

npm i @jdsalasc/solvejs

Quick example

import { parseDateStrict, slugify, uniqueBy, toNumber, deepMerge, retry, s } from "@jdsalasc/solvejs";

parseDateStrict("2026-02-07", "YYYY-MM-DD");
slugify("Build Better JS Apps");
uniqueBy([{ id: "a" }, { id: "a" }], (x) => x.id);
toNumber("1,200");
deepMerge({ app: { env: "dev" } }, { app: { version: 2 } });
await retry(() => fetch("https://example.com/health"), { retries: 2, delayMs: 150 });
s.object({ id: s.string().uuid() }).parse({ id: "550e8400-e29b-41d4-a716-446655440000" });
