TypeScript library starter that works out-of-the-box with Node, Deno, Bun, and the browser. Batteries included: linting, testing, bundling, size-limit, and automated releases.

Features

• Biome: lint and format with a single tool
• Vitest: fast tests with coverage and thresholds
• Size Limit: keep bundles tiny, with CI checks
• tsdown: ESM builds for Node and a separate browser bundle
• CI: lint, typecheck, test, coverage, and size comments/badges
• Release Please: automated release PRs and changelogs
• Commit Linting: conventional commits enforced in CI
• Deno-friendly: .ts source imports for direct consumption
• Multi-runtime: src/internal.ts is runtime-agnostic; src/index.ts (Node) and src/browser.ts (browser) wire runtime-specific APIs
• OIDC + Provenance: publish to npm and JSR via manual CI release

Usage

Install dependencies and run scripts:

pnpm i
pnpm lint
pnpm test
pnpm build

Node usage:

import { add, greet, getSecureRandomId } from "@bgub/ts-base";

console.log(add(2, 3));
console.log(greet("Ada"));
console.log(getSecureRandomId());

Browser usage (bundled or via import maps):

import { add, greet, getSecureRandomId } from "@bgub/ts-base/browser";

add(1, 2);
greet("Linus");
getSecureRandomId();

Deno usage (import from src if desired):

import { add, greet } from "https://jsr.io/@bgub/ts-base/<version>/src/index.ts";

Project Structure

• src/internal.ts: core logic, no Node/browser APIs
• src/index.ts: Node adapter (e.g., crypto.randomBytes)
• src/browser.ts: browser adapter (e.g., crypto.getRandomValues)
• tsdown.config.ts: builds Node entry and browser core bundle
• vitest.config.ts: coverage config and thresholds

Releasing

• Merge the automated Release PR created by Release Please
• Manually run the "Release" workflow to publish to npm and JSR with provenance
