SolveJS

SolveJS is a zero-dependency utility ecosystem for JavaScript and TypeScript apps.

Promise

Zero-dependency JS/TS utilities for real production pain points. Install one package or only the modules you need.

Popular Use Cases

• Parse dates from mixed input formats and convert wall-clock time across UTC offsets.
• Validate forms and API payloads with explicit error codes (phone, postal, IBAN, BIC, UUID, IPv4).
• Normalize strings for slugs/search and safely trim/mask UI output.
• Transform arrays/objects with predictable helpers (groupBy, flatten, deepMerge, path get/set).
• Control async workflows (retry, timeout, pMap, pSettle) without extra dependencies.

Why Teams Adopt SolveJS

• Predictable APIs with no runtime dependencies.
• ESM + CJS + TypeScript declarations across all packages.
• Structured validator responses for better UX/API error mapping.
• Problem-first cookbook docs with searchable recipes and integration guides.

Install

npm i @jdsalasc/solvejs

Install only specific modules:

npm i @jdsalasc/solvejs-date @jdsalasc/solvejs-validators @jdsalasc/solvejs-objects

Packages

• @jdsalasc/solvejs-date: parseDateMany, parseDateOrThrow, formatInUtcOffset, convertUtcOffset.
• @jdsalasc/solvejs-string: slugify, stripHtml, toTitleCase, truncate, mask.
• @jdsalasc/solvejs-list: uniqueBy, groupBy, flatten, partition, sortBy.
• @jdsalasc/solvejs-regex: REGEX_PATTERNS, validateByName, escapeRegex.
• @jdsalasc/solvejs-constants: TIME, FILE_SIZE_BYTES, HTTP_METHODS, parseBooleanString.
• @jdsalasc/solvejs-numbers: toNumber, safeDivide, percentChange, toCurrency.
• @jdsalasc/solvejs-validators: validateCellphoneNumber, validateIBAN, validateBIC, validateUuidV4.
• @jdsalasc/solvejs-objects: pick, omit, get, set, deepMerge.
• @jdsalasc/solvejs-async: sleep, timeout, retry, pMap, pSettle.
• @jdsalasc/solvejs-schema: s.object, parse/safeParse, Infer, toJsonSchema.

Quick Example

import { parseDateOrThrow, DateParseFormat, slugify, flatten, validateIBAN, deepMerge, retry, pSettle } from "@jdsalasc/solvejs";

parseDateOrThrow("07/02/2026", [DateParseFormat.DAY_MONTH_YEAR_SLASH]);
slugify("Build Better JS Apps");
flatten([1, [2, 3], 4]);
validateIBAN("GB33BUKB20201555555555");
deepMerge({ app: { env: "dev" } }, { app: { version: 2 } });
await retry(() => fetch("https://example.com/health"), { retries: 2, delayMs: 150 });
await pSettle([Promise.resolve("ok"), Promise.reject(new Error("fail"))]);
